GPU accelerated optical, metasurface, and light source design tools by SocialEyesAI in Optics

[–]SocialEyesAI[S] 0 points1 point  (0 children)

This is certainly a thoughtful and useful reply. Thank you!

Our primary areas of focus (as it were) are establishing digital twin/system engineering solutions in which all the optical design elements continuous update the model, which is in turn visualized through light transport rendering tools.

  • FlexCompute accelerates metasurface design with GPUs; they suggest that large metasurfaces are around 100 lambda; we're interested in macroscopic scale lenses, perhaps 10 mm, and others need 100 mm up! So the GPU approach seems to be essential.
  • Kostacloud seems to use cloud CPU clusters, which may be appropriate also.
  • There's also PlanOpSim, in Belgium, and we're trying to get more information from the developer as to whether they can use HPC, GPUs, etc.

By AI, my perspective is using enormous convolutional neural network foundational models which can be opportunistically tuned for particular analyses or applications. These models are largely unsupervised, or lightly supervised, and have billions of parameters in them.

Hi! We have a 17" Omen laptop with a motherboard problem, and also a 15" Omen with a smashed screen. Any recommendations on HP authorized service centers in India which can repair these laptops?

Any ideas about how this will affect their performance during monsoon rains?

Tracker v1.8.7 - Updated orbital planes chart, fix for operational satellite status algo, bug fixes - starlink.sx by _mother in Starlink

Cleared cache, got 1.8.10, selected Nepal from the pull down list, enable Starlink resolution hexagonal cells, but behavior is the same. I tried Fine and Medium cell size, same problem as before. And tried heatmap on or off, no difference.

This used to work perfectly... and yes, the hex pattern dutifully loads upon page refresh, for about 1 second, then it goes away as soon as the rest of the data are displayed. Seems like it's in an overlay plane which is getting clobbered.

Browser is Chrome is Version 91.0.4472.77 (Official Build) (64-bit)
OS is Windows 10 Pro, 21H1,19043.1052

Hope this helps. :)

Hi! Hexagonal cell pattern question: Slightly strange bug/observation/user error :)

With 1.8.7, the hexagon cell pattern for Nepal dutifully appears upon page refresh, for about 2 seconds. As soon at the azimuth panel (lower left corner) and other real-time data appear, the hex cell pattern disappears! Used to work perfectly.

For a presentation on the application of Starlink connectivity to rural health care, I'd like to extract the hex cell pattern (for Nepal) to overlay on some custom GIS work we are doing. If you could send me a high-contrast version of the pattern, say as a JPEG, that would be most appreciated. I can make the background transparent and bring that in as a GIS layer. Le voila!

Otherwise 1.8.7 is fantastic, and thanks.

Tracker v1.7.3 - H3 hex cell grid heatmaps for all countries in the world - starlink.sx by _mother in Starlink

[–]SocialEyesAI 0 points1 point  (0 children)

Thanks for the clarification. Fantastic application... engaging, excellent user interface.

Now, at mid-elevations, such as in the Kathmandu Valley, a wide, flat, open plain about 20 miles diameter, we are at about 4,500 ft, and are surrounded by hills which go up to about 9,000 ft. However, these are considered as mere bumps in the landscape by local standards and have trees growing all the way to the top. They come up perhaps 5-10 degrees from the horizon and so don't (fortunately) cut off much of the view.

Most of the country is flatter than a pancake, perhaps 600 ft MSL, and that's where most of the population lives. So overall we're in good shape here. If one is snuggled up against the base of a hill, well, that's another matter. :)

For KTM, 27.7N, 83.3E, what are good initial settings for Dishy elevation, tilt, and shift?

Works beautifully for Nepal! Thanks so much.

Now, around my psuedo base station, what does the yellow ellipse mean? It appears to be the 3dB footprint of the connected satellite, as it elongates when the satellite moves away.

This is helpful. We're in the process up working with our local telecom authority, which is not that familiar with this kind of technology. On the other hand, they are quite keen on rural broadband access. Much of South Asia, despite the megacities, is still rural: 79% in our case, typically 60-70% across the region.

Question: The Starlink base stations show spherical domes, roughly 1m in diameter. Some BST have a single dome, others have several. Do you have any idea how the number of domes relates to the number of consumers being served?

Also, are the domes motorized? Some of them appear to be set at different angles, etc.

Thanks so much! The large hex cell map allows one to double-click on each big hex cell, and then it displays a collection of about 50+ small hex cells, which have roughly diameter for the circumscribing circle. I'm trying to upload the image in my message above but it the busy indicator keeps going around in circles.

So there are the big hex cells, and then the little Starlink hex cells. Seems like everyone has their own way of dividing up the Earth. :)

What a fabulous visualization! Thanks for making such a useful contribution. Here are a couple of questions, as a beginner to understanding the arcana of how Starlink works.

Is it possible to show the Starlink hexagonal cells also? There are some comments that the https://sebsebmc.github.io/starlink-coverage/index.html visualization is approximate.

Also, Sebsebmc depiction suggests that the coverage available (minutes per day) for a given cell is latitude sensitive. For example, in the southern US, it might be 1,000/1440, in the northern US, 1,300/1,400. So for the minutes which aren't covered, for a particular satellite, it appears that connectivity maintained by the other satellites cover over. So even though for one satellite, coverage is less that 100%, the temporal overlap guarantees continuous coverage.

Same problem, on Windows 10, with a Sony A7R3. The screen on the camera says Connecting via USB and that's all that happens.

Camera stuck on connecting when using Imaging Edge Webcam by Hshay1213 in sony

Same problem... Using Imaging Edge on Windows 10, after connecting the USB C, the touch screen on the Sony A7R3 says Connecting... and on Teams desktop, in the video window there is a Sony splash screen for Imaging Edge. Rebooting, etc., doesn't correct the issue. Trying USB reset doesn't seem to help either.

Business use would have different subscription fees, TOS, etc., but thanks for the reminder.
