Those features are usually 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1117-1 00:05:41.853 --> 00:05:46.194 searched and mapped by field work in regional, small and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1117-2 00:05:46.194 --> 00:05:47.167 local region. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1139-0 00:05:47.497 --> 00:05:50.941 So our understanding of small scale geomorphic evidence 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1139-1 00:05:50.941 --> 00:05:53.893 remains limited in a comprehensive and big-data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1139-2 00:05:53.893 --> 00:05:54.877 context. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1162-0 00:05:56.327 --> 00:06:01.371 You figure out a way to automatically search for and map 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1162-1 00:06:01.371 --> 00:06:03.567 those small-scale features. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1169-0 00:06:03.577 --> 00:06:05.627 We can ask the following questions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1179-0 00:06:05.857 --> 00:06:08.707 How are the small scale-features spatially distributed? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1202-0 00:06:08.817 --> 00:06:12.032 How are they correlated with the each other? And how are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1202-1 00:06:12.032 --> 00:06:14.127 they correlated with large-scale features? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1211-0 00:06:14.517 --> 00:06:16.807 How do they reflect the ground motions? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1219-0 00:06:16.817 --> 00:06:20.087 Can they probabilistically inform future ruptures? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1228-0 00:06:20.297 --> 00:06:21.827 And how can they improve 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1233-0 00:06:21.837 --> 00:06:22.657 hazard analysis? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1273-0 00:06:24.087 --> 00:06:27.981 So in my previous work I had opportunity to look at the rocky 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1273-1 00:06:27.981 --> 00:06:31.435 fault scarp and the formation and the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1273-2 00:06:31.435 --> 00:06:35.517 development of rocky fault scarp involved three major processes. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-0 00:06:35.847 --> 00:06:40.514 Initially we have volcanic cooling which forms those 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-1 00:06:40.514 --> 00:06:46.237 columnar joints which are those large boulders, and then we have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-2 00:06:46.237 --> 00:06:51.255 to collect 14 which create displacements and also expose 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-3 00:06:51.255 --> 00:06:56.626 those large boulders to the surface and the border is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-4 00:06:56.626 --> 00:07:02.085 on the top, maybe top hold and fracture into small pieces and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1354-5 00:07:02.085 --> 00:07:06.927 the last process is referred as geomorphic fracturing. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1380-0 00:07:07.117 --> 00:07:11.821 It's probably very obvious that there are many large rocks on 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1380-1 00:07:11.821 --> 00:07:13.187 rocky fault scarp. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1398-0 00:07:13.397 --> 00:07:18.375 Our hypothesis is rock distributions reflected the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1398-1 00:07:18.375 --> 00:07:21.827 processes of rocky fault scarp development. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1418-0 00:07:23.817 --> 00:07:29.557 Of course, while engineering challenges, how can we map and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1418-1 00:07:29.557 --> 00:07:31.757 detect all these rocks? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-0 00:07:31.767 --> 00:07:36.656 Because the number is too large, so I came up with a data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-1 00:07:36.656 --> 00:07:41.714 processing pipeline which start from piloted aircraft 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-2 00:07:41.714 --> 00:07:46.519 system and using structure promotion we can get 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-3 00:07:46.519 --> 00:07:51.746 also map and DEM nothing new here and then we have used deep 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-4 00:07:51.746 --> 00:07:56.382 learning which is one branch of machine learning. Machine 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-5 00:07:56.382 --> 00:08:01.440 learning models and we have posted data processing and then 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1496-6 00:08:01.440 --> 00:08:03.547 we created a semantic map. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1554-0 00:08:03.617 --> 00:08:08.220 If you are familiar with GIS as you can consider a semantic map 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1554-1 00:08:08.220 --> 00:08:12.464 as a shapefile which composed of a large number of polygon 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1554-2 00:08:12.464 --> 00:08:16.923 vectors and each polygon vector describes outline of rock and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1554-3 00:08:16.923 --> 00:08:21.383 with a semantic map we can do geomorphic analysis and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1554-4 00:08:21.383 --> 00:08:24.547 trying to answer some scientific questions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1587-0 00:08:26.647 --> 00:08:32.532 And my research book, one of my research books is applying 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1587-1 00:08:32.532 --> 00:08:38.417 those cutting edge technologies for geoscience. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1602-0 00:08:38.707 --> 00:08:42.971 And when I'm applying some machine learning model to this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1602-1 00:08:42.971 --> 00:08:45.837 application, there are two challenges. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1615-0 00:08:46.017 --> 00:08:50.077 One is the first one is annotation map splitting. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1660-0 00:08:50.227 --> 00:08:53.918 That means when we have, when we use deep learning model, we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1660-1 00:08:53.918 --> 00:08:57.850 cannot train deep learning model with entire map because the map 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1660-2 00:08:57.850 --> 00:09:01.601 is too large and then you create a lot that requires a lot of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1660-3 00:09:01.601 --> 00:09:04.747 computation and memory for the deep learning model. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1695-0 00:09:04.897 --> 00:09:08.926 What we usually do is we split a large map, a large high 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1695-1 00:09:08.926 --> 00:09:13.238 resolution map to image tiles and the same time it will also 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1695-2 00:09:13.238 --> 00:09:16.207 split annotation map to annotation tiles. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1711-0 00:09:16.337 --> 00:09:21.207 So annotation map is something we draw those polygons on [indiscernible] 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1716-0 00:09:21.577 --> 00:09:21.877 [noise] 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1770-0 00:09:21.887 --> 00:09:26.151 [indiscernible] and it provides a subset of training data set to the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1770-1 00:09:26.151 --> 00:09:30.272 [indiscernible] model to train it, and once we have the [indiscernible] 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1770-2 00:09:30.272 --> 00:09:34.180 learning model, once we train the [indiscernible] 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1770-3 00:09:34.180 --> 00:09:38.657 learning model, we can use it to to predict other sites. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1780-0 00:09:39.047 --> 00:09:42.097 And one challenge is we have a large annotation map. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1796-0 00:09:42.107 --> 00:09:45.512 How can we split the large annotation map to annotation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1796-1 00:09:45.512 --> 00:09:45.877 tiles? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-0 00:09:46.167 --> 00:09:50.074 The other one is once we have the well trained [indiscernible] 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-1 00:09:50.074 --> 00:09:54.400 learning model and we get the prediction tiles and how can we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-2 00:09:54.400 --> 00:09:58.656 merge them to get a prediction map and those are the two 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-3 00:09:58.656 --> 00:10:02.563 challenges that hasn't been solved before and there are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-4 00:10:02.563 --> 00:10:07.098 probably other ways you can you can kind of solve this these two 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-5 00:10:07.098 --> 00:10:11.214 challenges and my focus my research focus is to come 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-6 00:10:11.214 --> 00:10:15.052 up, come up algorithms and data structure and then can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-7 00:10:15.052 --> 00:10:19.029 efficiently solve these two problems because when we are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-8 00:10:19.029 --> 00:10:23.494 dealing with large scale maps in remote sensing and computation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/1911-9 00:10:23.494 --> 00:10:25.517 efficiency is very important. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-0 00:10:25.567 --> 00:10:31.108 And so some results here from these 200 meter by 500 meter 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-1 00:10:31.108 --> 00:10:36.836 study area, we detected more than 200,000 thousand rocks and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-2 00:10:36.836 --> 00:10:42.940 on this major fault scarp, there are more than 30,000 rocks from 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-3 00:10:42.940 --> 00:10:49.044 this semantic map, we can create a heat maps by showing rocks 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-4 00:10:49.044 --> 00:10:54.773 or green size in meters and green size feet we can get today the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-5 00:10:54.773 --> 00:10:59.938 histogram of green size because we approximate each 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-6 00:10:59.938 --> 00:11:05.948 individual rock with a ellipse and then we use the eccentricity 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2018-7 00:11:05.948 --> 00:11:10.737 of the ellipse to represent the narrowness of the rock. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2048-0 00:11:11.007 --> 00:11:14.801 So we can get eccentricity distribution and shows the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2048-1 00:11:14.801 --> 00:11:18.594 narrow list distribution of those rocks and also rose 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2048-2 00:11:18.594 --> 00:11:22.247 diagram showing the rock orientation distributions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2072-0 00:11:24.627 --> 00:11:30.218 And then we study the coalition between rock size distribution 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2072-1 00:11:30.218 --> 00:11:33.057 and a fault scarp height. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2111-0 00:11:33.167 --> 00:11:37.812 What we found is on our higher fault scarp we have smaller big 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2111-1 00:11:37.812 --> 00:11:42.383 in green size and those are the rocks we present in the rocks 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2111-2 00:11:42.383 --> 00:11:43.857 here and the bottom. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2125-0 00:11:44.007 --> 00:11:46.627 That means a higher rock, higher fault scarp, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2153-0 00:11:46.807 --> 00:11:51.922 There are smaller those fractured rocks and those 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2153-1 00:11:51.922 --> 00:11:57.501 smaller rocks are kind of caused by a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2153-2 00:11:57.501 --> 00:11:59.547 geomorphic fracturing. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2179-0 00:11:59.737 --> 00:12:04.168 So that means that kind of indicate higher for the scarp 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2179-1 00:12:04.168 --> 00:12:08.287 has probably accumulated more geomorphic fracturing. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2208-0 00:12:08.397 --> 00:12:12.880 fault scarp and we found that 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2208-1 00:12:12.880 --> 00:12:15.767 there are larger boulders on the top. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2221-0 00:12:16.217 --> 00:12:20.589 And those larger boulders are are displaced by tectonic 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2221-1 00:12:20.589 --> 00:12:21.107 faulting. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2237-0 00:12:21.557 --> 00:12:25.027 So which also kind of indicate our higher fault scarp 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2241-0 00:12:25.037 --> 00:12:27.727 has accumulated more tectonic faulting. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2282-0 00:12:29.827 --> 00:12:34.395 This is probably very obvious, but this is kind of the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2282-1 00:12:34.395 --> 00:12:39.118 studies about the rock evidence of large scale 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2282-2 00:12:39.118 --> 00:12:42.757 geomorphic features and processes development. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2294-0 00:12:42.767 --> 00:12:45.607 In the process, we also 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2329-0 00:12:45.617 --> 00:12:49.835 examined or inspect uh particle transportation model, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2329-1 00:12:49.835 --> 00:12:53.985 so the medium size of the rock of the rocks are similar to a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2329-2 00:12:53.985 --> 00:12:55.277 size of a football. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2361-0 00:12:55.447 --> 00:12:59.081 If you think you can imagine you stand on the top of the Rocky 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2361-1 00:12:59.081 --> 00:13:01.157 for Skype and you throw a football. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2397-0 00:13:02.647 --> 00:13:06.581 And ideally with owl, ideally without some considering any 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2397-1 00:13:06.581 --> 00:13:10.514 friction and football will end up with orientation that is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2397-2 00:13:10.514 --> 00:13:13.047 parallel to the photo scope of trees. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2425-0 00:13:13.607 --> 00:13:18.695 And we studied rock orientation distribution and its correlation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2425-1 00:13:18.695 --> 00:13:23.704 with the the full scope height to support such kind of particle 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2425-2 00:13:23.704 --> 00:13:25.347 transportation model. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2437-0 00:13:28.117 --> 00:13:30.487 And a rock is just a rock. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2459-0 00:13:30.497 --> 00:13:34.717 Distribution is just one geomorphic evidence of footing, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2459-1 00:13:34.717 --> 00:13:38.641 and there are, as we just mentioned, there are other 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2459-2 00:13:38.641 --> 00:13:39.307 features. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2466-0 00:13:39.457 --> 00:13:42.887 For example, rocket cracks and displays the rocks. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2487-0 00:13:43.117 --> 00:13:47.830 This is from our Turkey earthquake earlier this year and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2487-1 00:13:47.830 --> 00:13:50.227 the rock was was here before. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2512-0 00:13:50.297 --> 00:13:55.104 It's about 2 meter height walk and from the earthquake the walk 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2512-1 00:13:55.104 --> 00:13:57.657 was displaced by 1.5 to 2 meters. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2526-0 00:13:58.527 --> 00:14:03.337 We should have triggered a creep and seismic rockfall. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2544-0 00:14:03.547 --> 00:14:09.448 And then you may expect on on for the trees, the vegetation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2544-1 00:14:09.448 --> 00:14:12.497 distributions can be different. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2565-0 00:14:15.807 --> 00:14:21.177 So for my research here at Caltech, I want to kind of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2565-1 00:14:21.177 --> 00:14:22.867 generalize those. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2581-0 00:14:22.927 --> 00:14:28.471 The rock, the feature detection from rock detection to a more 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2581-1 00:14:28.471 --> 00:14:32.137 general photo related feature detection. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2599-0 00:14:32.347 --> 00:14:37.844 For example, rock cracks at both the fractures that trigger the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2599-1 00:14:37.844 --> 00:14:39.647 creep and vegetation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2644-0 00:14:42.917 --> 00:14:48.675 And we are thinking about, I mean, Kate, Devin and me, we are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2644-1 00:14:48.675 --> 00:14:54.711 thinking about those study area candidates around Salton Sea, as 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2644-2 00:14:54.711 --> 00:14:59.447 you can see the photo structures on quite complex. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2675-0 00:14:59.517 --> 00:15:04.831 And this is also an area that is with less well understood and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2675-1 00:15:04.831 --> 00:15:07.867 there are many funders as medicity. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2707-0 00:15:07.877 --> 00:15:12.644 There are swarm of earthquakes, so if we we will see if we have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2707-1 00:15:12.644 --> 00:15:17.038 opportunity to so to have new earthquake and see how those 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2707-2 00:15:17.038 --> 00:15:20.687 features might, how those fractures may develop. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2736-0 00:15:23.767 --> 00:15:29.076 And they're constantly saying such a Jong, uh, light show on 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2736-1 00:15:29.076 --> 00:15:31.077 Twitter, which is cool. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2738-0 00:15:31.087 --> 00:15:31.387 OK. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2750-0 00:15:31.397 --> 00:15:35.317 We have Joe phone containment, but what about for signs? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2763-0 00:15:35.907 --> 00:15:38.477 So it's a swarm UAV mission planning. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2777-0 00:15:38.647 --> 00:15:42.663 This is quite important because after an earthquake it's 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2777-1 00:15:42.663 --> 00:15:44.777 important to scale up quickly. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2784-0 00:15:44.787 --> 00:15:46.217 Scale up your mapping. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2819-0 00:15:46.687 --> 00:15:51.097 For example, if we can find a new fractures and how can we use 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2819-1 00:15:51.097 --> 00:15:55.157 this new fractures to guide which is in the field so they 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2819-2 00:15:55.157 --> 00:15:58.657 can have a better idea of the earthquake effects? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2829-0 00:16:03.107 --> 00:16:06.757 Next is a technology development. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2838-0 00:16:07.367 --> 00:16:11.397 Next, technology development is automate augmented mapping. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2875-0 00:16:11.407 --> 00:16:15.444 So previous work I didn't assume we have any prior knowledge of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2875-1 00:16:15.444 --> 00:16:19.166 the of the study area, but that's not true because in most 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2875-2 00:16:19.166 --> 00:16:21.437 cases we have some prior knowledge. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2912-0 00:16:21.707 --> 00:16:25.282 If we have those prior knowledge, for example, if we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2912-1 00:16:25.282 --> 00:16:29.464 know the photo map and then we can use this photo map to have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2912-2 00:16:29.464 --> 00:16:31.757 information guided path planning. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2920-0 00:16:31.927 --> 00:16:35.887 To which we can improve the Joan mapping efficiency. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2939-0 00:16:39.027 --> 00:16:43.517 Also, we want to support this research photo zone mapping. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2968-0 00:16:43.527 --> 00:16:47.606 We we want to look at the the coalitions between features and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2968-1 00:16:47.606 --> 00:16:50.697 features and features and the ground emotions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2995-0 00:16:50.927 --> 00:16:55.779 And if we like, we do find those correlations, these strong 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/2995-1 00:16:55.779 --> 00:17:00.227 correlations, and we can do active search and mapping. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3041-0 00:17:00.237 --> 00:17:04.232 That means if we can find the feature A and also feature A and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3041-1 00:17:04.232 --> 00:17:07.719 feature B have strong correlations, and very likely we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3041-2 00:17:07.719 --> 00:17:11.650 will find if we find feature a from the drone and very likely 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3041-3 00:17:11.650 --> 00:17:14.567 the drone can also find feature being nearby. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3054-0 00:17:15.077 --> 00:17:16.587 Similar idea. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3084-0 00:17:16.727 --> 00:17:21.038 If we find earthquake and follow the ground, motion has some 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3084-1 00:17:21.038 --> 00:17:24.642 correlation with the some features and we have new 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3084-2 00:17:24.642 --> 00:17:29.093 earthquake that we can probably use this information to search 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3084-3 00:17:29.093 --> 00:17:30.577 new new new raptures. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3108-0 00:17:32.517 --> 00:17:36.149 OK, moving from Photozone mapping to fragile Judge Koh 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3108-1 00:17:36.149 --> 00:17:40.507 features, I specifically look at the precariously balanced rocks. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3127-0 00:17:40.577 --> 00:17:44.870 So those are the rocks that are balanced down but not attached 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3127-1 00:17:44.870 --> 00:17:45.687 to pedestal. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3171-0 00:17:45.907 --> 00:17:50.412 So if you go to field, you see a PR and that might indicate for a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3171-1 00:17:50.412 --> 00:17:54.507 while there hasn't been large earthquakes and also not just 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3171-2 00:17:54.507 --> 00:17:55.667 the PR's on ours. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3194-0 00:17:55.677 --> 00:18:00.845 Ours, we also found PPRS on Mars, so those are the photos 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3194-1 00:18:00.845 --> 00:18:02.627 from Mars 2020 over. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3208-0 00:18:04.037 --> 00:18:08.655 And there are many ways you can study the the fragility of PBR 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3208-1 00:18:08.655 --> 00:18:10.487 and one simple parameter. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3241-0 00:18:10.497 --> 00:18:14.621 One intuitive parameter is minimum contact angle, so you 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3241-1 00:18:14.621 --> 00:18:18.890 can see after an earthquake if PBR is toppled and then the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3241-2 00:18:18.890 --> 00:18:21.567 minimum contact angle will increase. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3252-0 00:18:21.577 --> 00:18:25.107 So this minimum contact angle is 1 parameter. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3259-0 00:18:25.117 --> 00:18:28.137 You can describe how fragile a PBR is. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3276-0 00:18:30.437 --> 00:18:33.967 And a reason a reason to research by two men. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3296-0 00:18:34.257 --> 00:18:38.346 And they are looking at this study area and between the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3296-1 00:18:38.346 --> 00:18:41.047 border of California and the Nevada. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3312-0 00:18:41.117 --> 00:18:47.265 So even before 2000 and the James James Booty founded those 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3312-1 00:18:47.265 --> 00:18:47.777 PR's. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3329-0 00:18:48.357 --> 00:18:50.747 Uh, it's quite pretty. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3351-0 00:18:50.757 --> 00:18:55.416 And there's just balanced here, but after a recent earthquake, a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3351-1 00:18:55.416 --> 00:18:59.717 man be magnitude 6 earthquake and the PR's are still there. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3358-0 00:19:00.877 --> 00:19:02.777 But they also observed the rock falls. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3400-0 00:19:03.857 --> 00:19:09.259 So what they found is OK, the PGA is PGA of point, 3G is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3400-1 00:19:09.259 --> 00:19:14.945 probably large enough to table PBR, but they also found the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3400-2 00:19:14.945 --> 00:19:18.167 tuition is too small to table it. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3423-0 00:19:18.247 --> 00:19:24.510 So to tumble PMR to topple PR, you need both large PGA and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3423-1 00:19:24.510 --> 00:19:28.437 duration, so that bring us bring us. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3441-0 00:19:28.447 --> 00:19:32.268 That brings us a questions or what constitutes fragile 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3441-1 00:19:32.268 --> 00:19:34.907 judgable features in a broader sense. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3492-0 00:19:35.007 --> 00:19:39.994 So we know PR's and Rock Peters are typically considered as 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3492-1 00:19:39.994 --> 00:19:45.480 fragile geological features, but in this case we have block falls 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3492-2 00:19:45.480 --> 00:19:50.716 and and but we didn't observe the table PBR, so our how can we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3492-3 00:19:50.716 --> 00:19:53.957 quantify the the fragility of an area? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3520-0 00:19:53.967 --> 00:19:58.467 Can we also come up with some idea to to quantify the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3520-1 00:19:58.467 --> 00:20:01.967 fragility of lab, landslide and rockfall? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3590-0 00:20:02.217 --> 00:20:07.069 And also previously I mean existing researchers only look 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3590-1 00:20:07.069 --> 00:20:12.255 at no one or several individual specific PBR's, but there are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3590-2 00:20:12.255 --> 00:20:17.358 many PR's and if we can map and do, if we can map and detect 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3590-3 00:20:17.358 --> 00:20:22.795 those large number of PR's, how can a large number of FGFS offer 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3590-4 00:20:22.795 --> 00:20:25.137 insights into going motions? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3615-0 00:20:25.527 --> 00:20:29.439 Because if we have a few samples and we the samples might be 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3615-1 00:20:29.439 --> 00:20:32.517 biased by free, look at the large distribution. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3628-0 00:20:32.597 --> 00:20:35.327 And might be a better or more accurate representation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3646-0 00:20:37.907 --> 00:20:41.857 So in my previous work I have this data processing pipeline. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-0 00:20:42.067 --> 00:20:45.768 I have US survey and soft structure from motion and we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-1 00:20:45.768 --> 00:20:49.805 have also mosaic and use the same 2 drug detection model to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-2 00:20:49.805 --> 00:20:54.043 detect the PBR's and also map and then we use the bounding box 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-3 00:20:54.043 --> 00:20:58.080 to crop the PR's on point cloud and we have another machine 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-4 00:20:58.080 --> 00:21:01.983 learning deep learning module to do the segmentation rock 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3718-5 00:21:01.983 --> 00:21:02.857 segmentation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3721-0 00:21:03.407 --> 00:21:04.417 Rock segmentation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3729-0 00:21:04.427 --> 00:21:07.317 So this method is offboard method. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3737-0 00:21:07.407 --> 00:21:08.417 What does it that means? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3760-0 00:21:08.977 --> 00:21:12.856 So outward method is separates the data collection and data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3760-1 00:21:12.856 --> 00:21:13.567 processing. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3807-0 00:21:13.637 --> 00:21:18.371 So in this case we have to pre plan a flight trajectory for the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3807-1 00:21:18.371 --> 00:21:23.031 drone and the drone collect the data and then we can come back 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3807-2 00:21:23.031 --> 00:21:27.248 to office and then we can process the data on the laptop 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3807-3 00:21:27.248 --> 00:21:28.727 or survey or server. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3851-0 00:21:30.727 --> 00:21:35.193 And the problem is if we we plan a flight trajectory for the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3851-1 00:21:35.193 --> 00:21:39.367 drone and in some case the minimum contact angle is very 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3851-2 00:21:39.367 --> 00:21:43.833 small and the drone may miss this, this very important basal 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3851-3 00:21:43.833 --> 00:21:45.297 contact information. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3864-0 00:21:46.087 --> 00:21:52.357 So to solve this problem I come up with a onboard method. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3873-0 00:21:52.467 --> 00:21:57.817 So we build these customized UV from scratch. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3880-0 00:21:57.907 --> 00:22:00.117 This one has two companion computers. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3893-0 00:22:00.127 --> 00:22:02.177 One is in charge of trajectory planning. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3934-0 00:22:02.607 --> 00:22:07.356 Another one has an age GPU that enables onboard machine learning 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3934-1 00:22:07.356 --> 00:22:11.593 in real time and RTK GPS and two stereo cameras 1/4 joint 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3934-2 00:22:11.593 --> 00:22:15.027 localization, the other one for drone mapping. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3985-0 00:22:15.997 --> 00:22:20.321 So again, the off board method is kind of separate the data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3985-1 00:22:20.321 --> 00:22:24.717 processing and the data, data collection and data processing 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3985-2 00:22:24.717 --> 00:22:29.040 and on board method because we we we we equipped those very 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3985-3 00:22:29.040 --> 00:22:33.364 powerful computers and we can integrate data collection and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3985-4 00:22:33.364 --> 00:22:34.517 data processing. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/3995-0 00:22:37.577 --> 00:22:39.667 So the idea is very straightforward. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4010-0 00:22:39.677 --> 00:22:42.107 So we haven't drawn do this. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4032-0 00:22:42.117 --> 00:22:45.869 Do this survey from a high lawn mower survey from a high 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4032-1 00:22:45.869 --> 00:22:46.527 elevation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4069-0 00:22:46.917 --> 00:22:51.627 Once it can detect the PBR from this camera and the real time 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4069-1 00:22:51.627 --> 00:22:55.957 machine learning and then it will move around to collect 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4069-2 00:22:55.957 --> 00:22:59.908 images from multiple perspectives to verify if it's 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4069-3 00:22:59.908 --> 00:23:00.667 PR or not. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4085-0 00:23:00.797 --> 00:23:03.298 Because if we use machine learning, we may have false 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4085-1 00:23:03.298 --> 00:23:03.807 detections. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4121-0 00:23:03.957 --> 00:23:08.398 This this process to just verify the PBR candidates and once the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4121-1 00:23:08.398 --> 00:23:12.565 PR is verified they will fly closer to the PBR and conduct a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4121-2 00:23:12.565 --> 00:23:15.297 circular motion to map it in real time. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4126-0 00:23:18.817 --> 00:23:19.247 Cool. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4147-0 00:23:19.257 --> 00:23:23.836 Once we can map once, we can map PR's and then we need to study 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4147-1 00:23:23.836 --> 00:23:25.267 the dynamics of PBS. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4161-0 00:23:25.507 --> 00:23:31.447 And so I build a virtual shake robot and a mini shake robot. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4174-0 00:23:31.857 --> 00:23:34.467 It's essentially the those are shake tables. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4216-0 00:23:34.477 --> 00:23:38.764 I I call it robots because I use the technologies and concepts in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4216-1 00:23:38.764 --> 00:23:42.531 robots like the control and perception model and also use 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4216-2 00:23:42.531 --> 00:23:46.558 the tools in robotics to build those two virtual and physical 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4216-3 00:23:46.558 --> 00:23:47.207 shippable. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4232-0 00:23:48.297 --> 00:23:50.887 And you can see and it's not just the the the. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4254-0 00:23:50.947 --> 00:23:54.245 The model is pretty straightforward and base near 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4254-1 00:23:54.245 --> 00:23:58.267 linear rail and a pedestal and PVR which very training here. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4305-0 00:23:58.277 --> 00:24:03.325 It's actually 22.5 meter height and also we can replace the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4305-1 00:24:03.325 --> 00:24:08.793 pedestal with realistic terrains and mapped by UV and do uh from 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4305-2 00:24:08.793 --> 00:24:14.008 the meaning from the mini shake table and we can use it to to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4305-3 00:24:14.008 --> 00:24:17.457 study the overturning of 3D printed PBR. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4321-0 00:24:17.547 --> 00:24:22.917 So this is a small downsized 3D printed PBR. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4331-0 00:24:23.007 --> 00:24:25.637 Just just the purpose is to verify the simulation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4336-0 00:24:28.027 --> 00:24:28.697 OK. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4361-0 00:24:28.827 --> 00:24:32.411 I particularly look at it two processes, one is overturning, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4361-1 00:24:32.411 --> 00:24:34.937 so this is a short term reaction from PBR. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4396-0 00:24:34.947 --> 00:24:39.840 So with the ground motion, if a PBR will topple, be not be not 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4396-1 00:24:39.840 --> 00:24:44.577 and and the other one is a long term long term PBR response. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4404-0 00:24:44.587 --> 00:24:46.297 Recall large displacement. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4449-0 00:24:46.307 --> 00:24:50.640 So once the PR is toppled and the what the trajectory it can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4449-1 00:24:50.640 --> 00:24:54.546 possibly have and we have 12 parallel simulations here 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4449-2 00:24:54.546 --> 00:24:58.382 because people are not symmetric, I mean the geometry 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4449-3 00:24:58.382 --> 00:25:00.157 people are not symmetric. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4465-0 00:25:00.167 --> 00:25:03.887 So we want to study the overturning response with with 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4465-1 00:25:03.887 --> 00:25:06.457 respect to different ground emotions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4474-0 00:25:06.547 --> 00:25:08.297 So for those 12 similar. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4488-0 00:25:08.307 --> 00:25:12.758 So those for those 12 parallel simulations, they have different 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4488-1 00:25:12.758 --> 00:25:14.427 initial PR orientations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4497-0 00:25:17.137 --> 00:25:18.367 So why don't we learn this? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4501-0 00:25:20.317 --> 00:25:20.787 Uh. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4519-0 00:25:20.797 --> 00:25:25.170 From overturning experiment we can get upper bound ground 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4519-1 00:25:25.170 --> 00:25:26.527 motion constraint. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4525-0 00:25:26.657 --> 00:25:27.767 So the red dots. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4536-0 00:25:27.777 --> 00:25:30.587 So this is the overturning response diagram. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4563-0 00:25:30.657 --> 00:25:34.623 So the reader dots represent the status that PR is coupled from 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4563-1 00:25:34.623 --> 00:25:38.217 the ground motion, and the Buddhas represent the balanced 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4563-2 00:25:38.217 --> 00:25:38.527 ctas. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4590-0 00:25:39.017 --> 00:25:42.573 So if you go to field, if you find the PR, that means if you 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4590-1 00:25:42.573 --> 00:25:45.137 find the PR, that means the quantum motion. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4615-0 00:25:47.157 --> 00:25:53.774 Is is not hasn't he hasn't exceeded this this this upper 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4615-1 00:25:53.774 --> 00:25:55.747 bound constraint. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4665-0 00:25:55.757 --> 00:26:00.301 This boundary and from a large displacement experiment and for 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4665-1 00:26:00.301 --> 00:26:04.989 example, if you go to field and you feel you, you can see if you 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4665-2 00:26:04.989 --> 00:26:09.677 find a tuple PBR and if you also happen to know it's trajectory. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4706-0 00:26:09.687 --> 00:26:14.052 For example, if we say if you know the trajectory is 30 meters 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4706-1 00:26:14.052 --> 00:26:18.002 and then from this large displacement experiment we know 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4706-2 00:26:18.002 --> 00:26:22.298 the ground motion for example this one has to be greater than 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4706-3 00:26:22.298 --> 00:26:23.337 this threshold. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4725-0 00:26:23.587 --> 00:26:27.690 Otherwise, if it's smaller, it cannot really result trajectory 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4725-1 00:26:27.690 --> 00:26:28.797 that is 30 meter. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4745-0 00:26:28.867 --> 00:26:32.987 So from the large displacement experiment, we can we can get a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4745-1 00:26:32.987 --> 00:26:35.407 lower bounded one motion constraint. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4776-0 00:26:35.817 --> 00:26:39.808 So with so we can combine overturning and large 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4776-1 00:26:39.808 --> 00:26:44.546 displacement, we can have a better upper bound and lower 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4776-2 00:26:44.546 --> 00:26:49.617 bound ground motion constraints for for the hazard analysis. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4791-0 00:26:52.407 --> 00:26:54.797 And there are some limitations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4832-0 00:26:54.807 --> 00:26:59.460 In my previous previous work, the off word method off word off 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4832-1 00:26:59.460 --> 00:27:03.743 word mapping method because I used deep learning model to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4832-2 00:27:03.743 --> 00:27:08.100 segment point clouds and it is supervised machine learning 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4832-3 00:27:08.100 --> 00:27:08.617 models. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4883-0 00:27:08.627 --> 00:27:12.880 That means I need annotations and annotating a point clouds is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4883-1 00:27:12.880 --> 00:27:17.066 very different annotating images because annotating point has 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4883-2 00:27:17.066 --> 00:27:21.117 very time consuming and for the onboard mapping method, the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4883-3 00:27:21.117 --> 00:27:23.817 flight time is quite quite a challenge. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4925-0 00:27:24.107 --> 00:27:27.877 And also I didn't consider obstacles because in reality and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4925-1 00:27:27.877 --> 00:27:31.520 there are there might be obstacles around PR, for example 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4925-2 00:27:31.520 --> 00:27:34.347 vegetations or PR that is very close to all. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4950-0 00:27:35.287 --> 00:27:40.610 And the virtual Shaker World War Two only has one one degree, one 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4950-1 00:27:40.610 --> 00:27:44.077 emotion, and this is one major limitation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4979-0 00:27:44.187 --> 00:27:50.166 So for for the PBR study, we are looking at the same study area 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4979-1 00:27:50.166 --> 00:27:54.837 and that's Jim Broom and Trugman Dukan to before. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/4998-0 00:27:57.247 --> 00:28:01.407 Now we just went there like uh, from from Friday to no. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5007-0 00:28:01.417 --> 00:28:05.067 From Sunday to and we come back, we came back yesterday night. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5036-0 00:28:06.707 --> 00:28:10.499 And so to improve the off boarding method, I have this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5036-1 00:28:10.499 --> 00:28:13.257 idea of semantic structure from motion. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5057-0 00:28:13.267 --> 00:28:17.434 So structure from motion is not new, but how can we use create 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5057-1 00:28:17.434 --> 00:28:20.277 semantics for structure motions, products? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5083-0 00:28:20.387 --> 00:28:23.759 So if we can combine deep learning and structure from 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5083-1 00:28:23.759 --> 00:28:27.568 motion, we can get the point cloud that is, that is for each 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5083-2 00:28:27.568 --> 00:28:28.817 point is classified. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5098-0 00:28:31.357 --> 00:28:35.507 And also off word method has some limitations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5119-0 00:28:35.517 --> 00:28:38.875 It couldn't really see the basal contact information, but it 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5119-1 00:28:38.875 --> 00:28:41.682 still can provide us some information about the PR 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5119-2 00:28:41.682 --> 00:28:42.287 candidates. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5180-0 00:28:42.397 --> 00:28:46.196 So some of them, even them, are not that fragile, but it can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5180-1 00:28:46.196 --> 00:28:49.373 provide the candidates information for the onboard 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5180-2 00:28:49.373 --> 00:28:52.923 method and then onboarding method can save the five time 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5180-3 00:28:52.923 --> 00:28:56.785 and skip skip searching, skip the time for searching and only 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5180-4 00:28:56.785 --> 00:28:59.587 focus on the mapping of those PR candidates. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5192-0 00:29:02.057 --> 00:29:04.147 And what I'm particularly interesting. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5195-0 00:29:04.407 --> 00:29:04.667 Uh. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5222-0 00:29:04.677 --> 00:29:09.337 Combining UAV, LIDAR and structure for motion so from UB 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5222-1 00:29:09.337 --> 00:29:11.707 Lidar it can, it can provide. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-0 00:29:12.057 --> 00:29:16.904 It can provide a good accuracy about the about the point cloud, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-1 00:29:16.904 --> 00:29:21.525 but in the resolution that are very good and I also couldn't 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-2 00:29:21.525 --> 00:29:25.614 provide a good texture and precision is not very good 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-3 00:29:25.614 --> 00:29:30.083 because the precision of the points might uh slow floating 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-4 00:29:30.083 --> 00:29:34.703 around some centimeter and UAB structure from motion mapping 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-5 00:29:34.703 --> 00:29:39.475 system and can provide a good position and also the texture is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-6 00:29:39.475 --> 00:29:43.943 also good but the quality is not very good and also it has 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5322-7 00:29:43.943 --> 00:29:47.957 problem of global deformation and local deformation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5373-0 00:29:48.117 --> 00:29:51.990 The global deformation can be corrected by ground control 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5373-1 00:29:51.990 --> 00:29:56.263 points, but if we want to study small skill features like those 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5373-2 00:29:56.263 --> 00:30:00.336 triggered creep that only have the development of three to 7 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5373-3 00:30:00.336 --> 00:30:04.543 millimeters a year, we do need to to fix the local deformation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5373-4 00:30:04.543 --> 00:30:05.077 problem. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5400-0 00:30:05.827 --> 00:30:11.354 So if we can combine LIDAR and structure from motion, and to do 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5400-1 00:30:11.354 --> 00:30:16.277 that can provide us a, maybe a new novel mapping system. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5426-0 00:30:18.617 --> 00:30:22.473 And also virtual Shaker robot that kind of want to expand the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5426-1 00:30:22.473 --> 00:30:26.142 from one one degree granting motion to three degree ground 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5426-2 00:30:26.142 --> 00:30:26.577 motion. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-0 00:30:28.587 --> 00:30:32.697 And in you may see that can there are many projects, many 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-1 00:30:32.697 --> 00:30:36.522 development, technology development and but projects, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-2 00:30:36.522 --> 00:30:40.348 but there are quite a large overlap between these two 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-3 00:30:40.348 --> 00:30:44.529 studies for for example, the semantic structure for motion 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-4 00:30:44.529 --> 00:30:48.142 can be used for photozone mapping and also fragile 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5486-5 00:30:48.142 --> 00:30:49.417 tragical features. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5507-0 00:30:50.027 --> 00:30:54.122 And this is one advantage of this of of such kind of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5507-1 00:30:54.122 --> 00:30:54.817 research. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5523-0 00:30:54.927 --> 00:30:58.592 Once the technology is developed, we can we can easily 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5523-1 00:30:58.592 --> 00:31:01.657 transfer that the technology to other domain. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5530-0 00:31:04.057 --> 00:31:05.737 And project management. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-0 00:31:05.957 --> 00:31:10.412 So we usually have off board, off board or offline method that 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-1 00:31:10.412 --> 00:31:14.796 use commercial drones and we just use a drone to collect data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-2 00:31:14.796 --> 00:31:18.685 and then we focus on data processing also have onboard 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-3 00:31:18.685 --> 00:31:22.786 method and onboard requires hardware development and this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-4 00:31:22.786 --> 00:31:26.675 sounds easy, but it's quite there are many components, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-5 00:31:26.675 --> 00:31:30.847 mechanical design, electrical design and you need to think 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5610-6 00:31:30.847 --> 00:31:32.827 about what sensors you need. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5621-0 00:31:32.837 --> 00:31:35.774 You need to use and in the battery management 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5621-1 00:31:35.774 --> 00:31:36.667 communication. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5659-0 00:31:37.067 --> 00:31:41.043 The communication between the UV and the operator and if you want 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5659-1 00:31:41.043 --> 00:31:44.718 to have multiple UV mapping system you also need to consider 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5659-2 00:31:44.718 --> 00:31:48.393 communication among Jones and simulation tests, because once 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5659-3 00:31:48.393 --> 00:31:49.417 you develop this. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5677-0 00:31:50.737 --> 00:31:54.007 Hardware and you just go to feel the very likely you will. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5686-0 00:31:54.017 --> 00:31:55.567 You will crash it so. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5716-0 00:31:55.677 --> 00:31:58.999 So usually we have we will test the Jones and test the software 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5716-1 00:31:58.999 --> 00:32:01.957 in a simulation and we are ready and we have field test. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5766-0 00:32:03.047 --> 00:32:06.632 So the off board method is the offline method is more 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5766-1 00:32:06.632 --> 00:32:10.217 straightforward and the online method is require more 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5766-2 00:32:10.217 --> 00:32:14.466 technology development, but the online method is also promising 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5766-3 00:32:14.466 --> 00:32:18.648 and can do many things that the the off boarding method cannot 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5766-4 00:32:18.648 --> 00:32:18.847 do. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5776-0 00:32:21.357 --> 00:32:22.697 Let's go back to these. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5779-0 00:32:22.707 --> 00:32:23.287 Uh. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5795-0 00:32:23.327 --> 00:32:27.012 Ultimate issues science because I'm very interested in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5795-1 00:32:27.012 --> 00:32:29.357 philosophy of some of methodology. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5800-0 00:32:30.087 --> 00:32:31.997 So all this is start from. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5809-0 00:32:32.827 --> 00:32:36.237 Umm geoscientific observations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5820-0 00:32:36.247 --> 00:32:39.457 But what if geoscientific observations are not accessible 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5820-1 00:32:39.457 --> 00:32:40.397 or interpretable? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5837-0 00:32:40.607 --> 00:32:43.117 This sounds are abstract question, but it's quite common. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5864-0 00:32:43.127 --> 00:32:47.412 So before Mars Rover, close range marks observations are not 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5864-1 00:32:47.412 --> 00:32:51.345 accessible and volcanoes and deep oceans are not easily 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5864-2 00:32:51.345 --> 00:32:52.117 accessible. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5871-0 00:32:52.207 --> 00:32:54.477 Nowadays we have too much data. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5878-0 00:32:54.927 --> 00:32:55.857 There's too much data. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5895-0 00:32:55.867 --> 00:33:00.581 We cannot really interpolate them by person, so in this case, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5895-1 00:33:00.581 --> 00:33:01.417 how can we? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5902-0 00:33:01.507 --> 00:33:03.807 How can we handle those situations? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5941-0 00:33:04.317 --> 00:33:08.192 So what I'm what's the automated jewel size is proposing is to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5941-1 00:33:08.192 --> 00:33:11.576 use robots to make the sides more accessible and using 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5941-2 00:33:11.576 --> 00:33:14.897 machine learning to make the data more interpretable. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5978-0 00:33:16.287 --> 00:33:21.109 And then we kind of expanded the idea of automatic Jose as to a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5978-1 00:33:21.109 --> 00:33:25.555 general automated Jews as so we can use robots and machine 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/5978-2 00:33:25.555 --> 00:33:29.397 learning to to assist Geo scientific observations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6016-0 00:33:29.467 --> 00:33:34.515 So I I for a short time short term, I don't think we can like 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6016-1 00:33:34.515 --> 00:33:39.319 really use robots and the machine running to replace human 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6016-2 00:33:39.319 --> 00:33:40.377 observations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6032-0 00:33:40.527 --> 00:33:44.007 But now we can do this very high likelihood. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6061-0 00:33:44.017 --> 00:33:48.991 We can use these tools to assist observations, so this idea is we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6061-1 00:33:48.991 --> 00:33:52.307 will have more exploration driven research. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6089-0 00:33:52.617 --> 00:33:56.048 So sometimes we just have to explore more, collect more data 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6089-1 00:33:56.048 --> 00:33:59.705 and honest data, understand the data better, and then we can ask 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6089-2 00:33:59.705 --> 00:34:01.167 more meaningful questions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6107-0 00:34:03.667 --> 00:34:07.179 And then particularly interested in one application, it's 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6107-1 00:34:07.179 --> 00:34:09.237 disaster decision support system. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6135-0 00:34:09.357 --> 00:34:13.917 This is different from early warning, so this is we we have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6135-1 00:34:13.917 --> 00:34:17.717 data from centralized robots and sensor networks. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6155-0 00:34:17.807 --> 00:34:22.241 How can we use this data and combine them to build a disaster 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6155-1 00:34:22.241 --> 00:34:23.957 decision support system? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6163-0 00:34:24.007 --> 00:34:26.877 So once earthquake were tornado? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6196-0 00:34:26.987 --> 00:34:32.580 Hurricane Arthur and and then we can integrate this data and use 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6196-1 00:34:32.580 --> 00:34:37.657 that to assist a search and rescue and also maybe observe. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6208-0 00:34:38.147 --> 00:34:43.667 Uh recover weight to your long term and that's my presentation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6212-0 00:34:43.677 --> 00:34:44.877 Thank you every. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6221-0 00:34:45.007 --> 00:34:48.157 Thank you, everyone and I'm happy to take questions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6228-0 00:34:54.747 --> 00:34:55.647 Thank you so much. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6243-0 00:34:56.477 --> 00:35:02.924 Umm, so there's there's people clapping here, I guess well of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6243-1 00:35:02.924 --> 00:35:04.067 my Moffett. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6249-0 00:35:04.077 --> 00:35:05.237 Menlo gets warmed up. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6257-0 00:35:05.247 --> 00:35:06.587 If there's any questions in the room. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6259-0 00:35:07.967 --> 00:35:08.227 Yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6261-0 00:35:08.287 --> 00:35:08.937 Yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6270-0 00:35:08.987 --> 00:35:10.967 So thanks for really excited presentation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6307-0 00:35:11.047 --> 00:35:16.447 I was wondering on the so the figure you showed where you had 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6307-1 00:35:16.447 --> 00:35:21.759 the PGA versus ratio PGA PGB toppling versus not there was a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6307-2 00:35:21.759 --> 00:35:22.717 clear line. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6415-0 00:35:22.727 --> 00:35:27.244 But to me, whether rock was gonna toggle or not, if a given 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6415-1 00:35:27.244 --> 00:35:31.686 acceleration, for example do obviously some uncertainty in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6415-2 00:35:31.686 --> 00:35:36.279 there so you don't know the contact between the rock and its 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6415-3 00:35:36.279 --> 00:35:38.537 pedestal and strong it is ohh. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-0 00:35:38.547 --> 00:35:42.726 Thinking about ways to address or include that kind of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-1 00:35:42.726 --> 00:35:47.285 uncertainty in uh in these in these types of plots, because 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-2 00:35:47.285 --> 00:35:52.072 part of the question goes to to understand what ground motions 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-3 00:35:52.072 --> 00:35:56.783 have happened in the past after we think about whether or not 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-4 00:35:56.783 --> 00:36:01.494 brown motion has been exceeded about the and based on whether 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6419-5 00:36:01.494 --> 00:36:04.077 or not a fragile too one feature. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6446-0 00:36:04.767 --> 00:36:09.563 So but if you have a bunch of fragile job geologic features, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6446-1 00:36:09.563 --> 00:36:14.594 maybe there's probability that some fraction of them believe in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6446-2 00:36:14.594 --> 00:36:14.987 that. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6456-0 00:36:16.267 --> 00:36:16.567 Sure. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6460-0 00:36:16.577 --> 00:36:17.847 Of my concert? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6462-0 00:36:18.437 --> 00:36:18.747 Yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6472-0 00:36:18.757 --> 00:36:21.777 So the first part is. So this is a. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6487-0 00:36:21.897 --> 00:36:27.085 This is a overturning response from experiment from one ground 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6487-1 00:36:27.085 --> 00:36:28.567 emotion direction. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-0 00:36:28.737 --> 00:36:32.864 So in simulation it's deterministic and we can we can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-1 00:36:32.864 --> 00:36:37.067 eventually we do need a probabilistic model if we want 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-2 00:36:37.067 --> 00:36:41.651 to incorporate it for hazard analysis and what we can do is 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-3 00:36:41.651 --> 00:36:46.466 we can do Monte Carlo and for example we can change the we can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-4 00:36:46.466 --> 00:36:51.051 kind of like slightly disturb the orientation a little bit, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-5 00:36:51.051 --> 00:36:55.483 not very large distribution distribution change not large 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6570-6 00:36:55.483 --> 00:36:58.157 orientation change but very small. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6593-0 00:36:58.167 --> 00:37:02.054 And we do a Monte Carlo simulations and we can get, uh, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6593-1 00:37:02.054 --> 00:37:06.287 we can build a probabilistic model for overturning response. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6601-0 00:37:07.447 --> 00:37:08.697 And I didn't capture. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6613-0 00:37:08.707 --> 00:37:12.617 The later part is there also that the question not really. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6648-0 00:37:12.627 --> 00:37:17.578 So I guess the other piece is just the sort of segmentation 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6648-1 00:37:17.578 --> 00:37:22.364 that between off the pedestal potentially and how how you 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6648-2 00:37:22.364 --> 00:37:24.427 understands the range of. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6652-0 00:37:26.177 --> 00:37:27.127 Possibilities. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6662-0 00:37:27.197 --> 00:37:30.587 Yeah, it's very it's very difficult the. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6689-0 00:37:31.587 --> 00:37:36.144 So the dynamics of PR is very complex, is definitely 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6689-1 00:37:36.144 --> 00:37:40.357 nonlinear, and even small change in the contact. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6706-0 00:37:40.367 --> 00:37:47.127 My hugely affected the fragility and there are hard research by 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6706-1 00:37:47.127 --> 00:37:48.817 Christine Wedge. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6721-0 00:37:48.967 --> 00:37:52.037 They did some work about the very sophisticated, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6721-1 00:37:52.037 --> 00:37:54.167 sophisticated models of studying. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6738-0 00:37:55.567 --> 00:37:58.929 Follow the contact how most small change of contact affect 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6738-1 00:37:58.929 --> 00:37:59.727 the fragility. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6761-0 00:38:00.017 --> 00:38:05.681 So I'm just thinking, well, we can build, we can build a very 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6761-1 00:38:05.681 --> 00:38:10.887 accurate world, very complex model for individual PBR's. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6799-0 00:38:11.197 --> 00:38:15.833 But if we really nap a large number of PR to see if we can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6799-1 00:38:15.833 --> 00:38:20.547 map 101,000 PBR, do we still need a very accurate model for 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6799-2 00:38:20.547 --> 00:38:21.647 individual PR? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6813-0 00:38:22.637 --> 00:38:26.687 Because we have a large number of people's, maybe we will see. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6835-0 00:38:26.697 --> 00:38:30.539 I don't know, but there's a very good opportunity that we can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6835-1 00:38:30.539 --> 00:38:33.947 that can provide a different perspective, right? Yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6861-0 00:38:38.277 --> 00:38:43.582 So the potential of repeat surveys to potentially look for 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6861-1 00:38:43.582 --> 00:38:48.347 creep along faults scribes Ridgecrest comes to mind. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6913-0 00:38:48.827 --> 00:38:52.914 Do you think you can get you the resolution to maybe tease out 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6913-1 00:38:52.914 --> 00:38:56.157 whether there is slow deformation happening along 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6913-2 00:38:56.157 --> 00:39:00.179 those uh surface exposures of rupture is and whatnot, is that 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/6913-3 00:39:00.179 --> 00:39:03.487 do you think that's possible with this technology?

few days ago, there are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8847-1 00:50:07.625 --> 00:50:12.066 and then they can new generation of RTK then do that does not 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8847-2 00:50:12.066 --> 00:50:15.217 require base station with quite surprising. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8858-0 00:50:15.347 --> 00:50:17.619 I don't know how how they did that, but there's some 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8858-1 00:50:17.619 --> 00:50:18.347 technology there. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8861-0 00:50:20.277 --> 00:50:21.987 Umm uh. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8869-0 00:50:24.117 --> 00:50:25.397 Yeah, let me think. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8877-0 00:50:26.867 --> 00:50:27.777 Yeah, I don't know. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8874-0 00:50:27.137 --> 00:50:27.487 OK. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8882-0 00:50:27.497 --> 00:50:27.847 Thank you. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8901-0 00:50:27.787 --> 00:50:33.670 Like a large RTQ is, is is one challenge and also there are 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8901-1 00:50:33.670 --> 00:50:37.787 many other challenges like communication. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8926-0 00:50:37.797 --> 00:50:42.201 I think that's some more, more important in this case, like how 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8926-1 00:50:42.201 --> 00:50:45.847 for example like in the field of work and yesterday. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8993-0 00:50:46.537 --> 00:50:52.262 So we are trying to map a very the Centennial plov and it's 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8993-1 00:50:52.262 --> 00:50:58.369 very deep and and when the drone is flying to the other side of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8993-2 00:50:58.369 --> 00:51:04.285 the slope and the huge huge a blocks of voters that block the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/8993-3 00:51:04.285 --> 00:51:04.857 radio. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9023-0 00:51:05.037 --> 00:51:08.507 And then when the radio is blocked and they don't have to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9023-1 00:51:08.507 --> 00:51:12.037 take off and take off and come back to the home point, no. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9043-0 00:51:12.047 --> 00:51:15.295 But I want to continue the mission and finish the mapping 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9043-1 00:51:15.295 --> 00:51:15.687 for me. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9063-0 00:51:15.757 --> 00:51:19.446 But somehow because the radio is disconnected and then they don't 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9063-1 00:51:19.446 --> 00:51:20.787 have to have to go back. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9088-0 00:51:20.897 --> 00:51:24.825 So I think the communication, for example, how can we use the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9088-1 00:51:24.825 --> 00:51:28.183 mobile communication communication radio tower to do 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9088-2 00:51:28.183 --> 00:51:29.767 a relay of communication. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9101-0 00:51:29.777 --> 00:51:33.971 I think those are the more challenging tasks for this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9101-1 00:51:33.971 --> 00:51:35.757 technology development. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9106-0 00:51:37.727 --> 00:51:38.107 Thank you. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9108-0 00:51:39.247 --> 00:51:40.157 Yeah, sure. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9115-0 00:51:40.627 --> 00:51:41.657 So are there other? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9118-0 00:51:41.017 --> 00:51:41.347 Out. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9122-0 00:51:41.707 --> 00:51:42.007 Ohh yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9130-0 00:51:42.777 --> 00:51:45.727 Yeah, this is 10 minute, Moffett Austin talk. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9133-0 00:51:45.737 --> 00:51:46.167 Thank you. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9156-0 00:51:46.177 --> 00:51:49.477 So and so I'll say that we're looking at urban things in the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9156-1 00:51:49.477 --> 00:51:50.937 Hayward fault this weekend. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9185-0 00:51:51.287 --> 00:51:53.990 And I'm wondering how technically and maybe like in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9185-1 00:51:53.990 --> 00:51:57.368 terms of regulation challenging is to do this kind of mapping in 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9185-2 00:51:57.368 --> 00:51:59.967 urban environments as mostly desert environments. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9194-0 00:52:01.337 --> 00:52:03.107 That's that's definitely quite a challenging. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9230-0 00:52:03.157 --> 00:52:07.875 I don't know how I can personally work with if AI to to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9230-1 00:52:07.875 --> 00:52:13.098 to work on, to work around those airspace regulations for for 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9230-2 00:52:13.098 --> 00:52:14.277 some airspace. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9253-0 00:52:14.287 --> 00:52:18.759 No, we cannot definitely fly, for example, those prohibited, 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9253-1 00:52:18.759 --> 00:52:21.837 uh, spare airspace 4 restricted airspace. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9281-0 00:52:21.847 --> 00:52:26.659 We can get permissions and also if if a has a regulation that 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9281-1 00:52:26.659 --> 00:52:30.849 you cannot really operate multiple Jones and the same 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9281-2 00:52:30.849 --> 00:52:31.237 time. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9317-0 00:52:31.427 --> 00:52:35.451 So we have to, we have to do something I have because I have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9317-1 00:52:35.451 --> 00:52:39.673 multiple UAV research is not a new I, but I don't know how much 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9317-2 00:52:39.673 --> 00:52:42.377 they they have done with the field work. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9332-0 00:52:42.387 --> 00:52:45.627 So I need to this is 1 professor. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9361-0 00:52:45.637 --> 00:52:50.158 I'm going to have a meeting later today and he did a lot of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9361-1 00:52:50.158 --> 00:52:55.132 work and Caltech, about Joan and also where we are thinking about 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9361-2 00:52:55.132 --> 00:52:56.337 multi UV system. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9368-0 00:52:56.447 --> 00:52:57.667 So of course I will see. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9384-0 00:52:58.207 --> 00:53:02.567 Uh, what do you have done about the multi UV system? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9401-0 00:53:02.577 --> 00:53:06.055 I mean how they work with if, how they work with the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9401-1 00:53:06.055 --> 00:53:06.777 regulation. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9419-0 00:53:07.177 --> 00:53:12.167 Uh ohso ration and also how they deal with these regulations. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9453-0 00:53:12.377 --> 00:53:15.124 I mean, logistics and regulations are are very 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9453-1 00:53:15.124 --> 00:53:18.805 important and yeah, we have we think we have to do, we have to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9453-2 00:53:18.805 --> 00:53:21.727 do something, but it's it's a very good question. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9476-0 00:53:23.857 --> 00:53:27.787 I and I've got one questions in action, neither I've offered. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9484-0 00:53:28.057 --> 00:53:31.007 So things first is young for a really impressive talk. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9530-0 00:53:31.717 --> 00:53:35.265 I was really intrigued by your ideas about automated 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9530-1 00:53:35.265 --> 00:53:39.483 geoscience, and I I share the idea that there's this challenge 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9530-2 00:53:39.483 --> 00:53:43.366 and having an excess of data that might make it even more 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9530-3 00:53:43.366 --> 00:53:47.315 difficult to actually explore that data to answer pressing 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9530-4 00:53:47.315 --> 00:53:48.587 research questions. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9555-0 00:53:49.077 --> 00:53:52.827 Can you talk about how you would use machine learning for 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9555-1 00:53:52.827 --> 00:53:56.770 interpreting the massive amounts of data that you're kind of 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9555-2 00:53:56.770 --> 00:53:57.287 working? 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9575-0 00:53:57.297 --> 00:54:01.569 Collect especially in light of the biases that machine learning 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9575-1 00:54:01.569 --> 00:54:02.837 methods often have. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9578-0 00:54:04.167 --> 00:54:04.557 Yeah. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-0 00:54:04.567 --> 00:54:09.428 For example you know mass Rover and there are many interesting 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-1 00:54:09.428 --> 00:54:13.904 rocks on Mars and and they they are building a a data a a 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-2 00:54:13.904 --> 00:54:18.688 category or no inven inventory of those rocks on Mars pattern 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-3 00:54:18.688 --> 00:54:23.472 was one when the when the when the Rover is is already moving 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-4 00:54:23.472 --> 00:54:28.333 already collected those those blocks but when we see they have 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-5 00:54:28.333 --> 00:54:33.040 to snow to you only need to do you only need to register new 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-6 00:54:33.040 --> 00:54:37.978 rocks that is not existed that does not exist in their existing 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-7 00:54:37.978 --> 00:54:42.376 database so they use So what they do is they have a much 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-8 00:54:42.376 --> 00:54:47.160 Rover and then they will they will have some more operator to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-9 00:54:47.160 --> 00:54:51.867 see a lot of missing a lot of images every day and then they 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-10 00:54:51.867 --> 00:54:56.883 need to say OK this is rocket is new and I need to put that into 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-11 00:54:56.883 --> 00:55:01.667 my database but the problem is they have a large database and 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-12 00:55:01.667 --> 00:55:06.605 the operators sometimes if you confused like is this we already 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-13 00:55:06.605 --> 00:55:11.312 registered So what they do is they have the machine learning 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-14 00:55:11.312 --> 00:55:16.019 is they have these called a novel novelty detection so based 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-15 00:55:16.019 --> 00:55:20.571 on their existing database between machine machine machine 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-16 00:55:20.571 --> 00:55:25.433 learning model and then when we see a new new rock that is not 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-17 00:55:25.433 --> 00:55:30.062 in the existing database and then they will be destroyed so 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-18 00:55:30.062 --> 00:55:35.001 in this case we have to you have to use machine learning and to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-19 00:55:35.001 --> 00:55:39.862 learn and then we can OK that's an interesting lesson you rock 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-20 00:55:39.862 --> 00:55:44.183 and also like distributed acoustic system and they also 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-21 00:55:44.183 --> 00:55:48.890 use machine learning to to pick to pick the the face I don't 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-22 00:55:48.890 --> 00:55:53.442 know exactly how they did that but they say I can acoustic 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-23 00:55:53.442 --> 00:55:58.149 signals they are there are is complicated and in most of the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-24 00:55:58.149 --> 00:56:03.088 time it's not an interesting and the when the earthquake occurs 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-25 00:56:03.088 --> 00:56:07.949 and the data can be different but we cannot really monitor the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-26 00:56:07.949 --> 00:56:12.964 data we we all the time so they have a machine learning model to 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-27 00:56:12.964 --> 00:56:18.057 monitor the data and and know OK that's a that's a novelty that's 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-28 00:56:18.057 --> 00:56:22.764 a novel thing that we haven't seen before and then we can we 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-29 00:56:22.764 --> 00:56:27.316 can we can record it or we can inspect it I mean this this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-30 00:56:27.316 --> 00:56:32.023 methodology is new and I'm still thinking about what are the 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-31 00:56:32.023 --> 00:56:36.730 challenges and what are the opportunities there because that 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-32 00:56:36.730 --> 00:56:41.437 can really change our way of thinking of the problems we can 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/9999-33 00:56:41.437 --> 00:56:42.517 have maybe if 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10005-0 00:56:49.127 --> 00:56:49.867 Awesome. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10020-0 00:56:50.027 --> 00:56:53.877 I think on that very positive, inspiring note, we can wrap this 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10020-1 00:56:53.877 --> 00:56:54.057 up. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10035-0 00:56:55.067 --> 00:56:58.617 So thanks everybody for joining us and have a great Wednesday. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10038-0 00:56:59.367 --> 00:57:00.017 Thank everyone. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10051-0 00:57:06.057 --> 00:57:06.667 Wow. 3a125a5c-cc4a-477f-8c1c-61d5bdb4bf00/10058-0 00:57:07.017 --> 00:57:08.477 That's like, that's pretty cool, actually.
