As the quantum detectors get more sensitivity they should be picking up fluctuations in the local gravitational potential and electromagnetic background fields of the earth. But I have not seen anyone running a detector continuously for the days or weeks or months needed to do the required correlations to trace things out. Nor, do I

Jordan, Image Acquisition Toolbox: Your online, and now the attached price list, is not appropriate for “Home” users. Today someone fixed the website issue where the license information was not accessible. I could not open my account information. Now, when I look at my account information, “Manage Products”, it has “But Add-Ons” as a working

LOL! When I clicked OK it failed because it could not read my email address. I used mixed case, that is probably why it failed. Why do I even bother trying to help anyone. I can act in good faith and try to do my best to document something. But the systems on the Internet

https://www.facebook.com/groups/172438633343696/permalink/877591389495080/ I am looking at daytime uses of all sky cameras. Satellite images are a bit too bulky and not enough resolution for correlations. Need multiple cameras to recover 3D of clouds. I have seen groups aiming at comets, planes, clouds, rain, sky color, daytime astronomy (is possible), sun and moon tracking, shadows, reflections, multispectral,

Robin, Haje, I am looking at global sensor networks, and got to magnetotelluric arrays. For background I was reading about natural signals that can be used for calibration and reference and came to http://ampere.jhuapl.edu/index.html To be explicit, I was at https://en.wikipedia.org/wiki/Birkeland_current and clicked on the link to Project Ampere that took me to https://web.archive.org/web/20050211120508/http://dysprosium.jhuapl.edu/ Then

https://www.researchgate.net/post/Is_there_any_paper_scientific_document_that_shows_how_much_mA_is_typically_considered_as_the_input_current_in_the_ERT_and_IP_fields2 Mostafa Ebrahimi, When you ask questions like this, spell out what all the acronyms. IP is mostly “intellectual property” or other things on the Internet. “electrical resistivity tomography” “induced polarization” gives 42,100 entries on Google search. That means it is fairly mature. If you are actively surveying a large region you might

£700 vs £7,000,000: Astrophotography Shoot Out https://www.youtube.com/watch?v=4rCyC3_YIME Ryan Fay? Your link in the description is broken (luckyimage) should probably be https://www.astrobiscuit.com/deepspaceluckyimaging There are better ways to combine images from many different sensors. You talked about hundreds?, thousands?, millions?, billions? of people combining images to improve earth surface imaging. Take the human out of the loop.

Strings are just one example of the larger problem of sequences and patterns (any dimensions). This morning, I am just surveying the Internet for rock types and measurements used in geochemistry. There are many methods and representations. Does the student like to explore, to gather, to find general patterns, to share what they have found,

Hello, I was at https://www.virgo-gw.eu/#about and clicked on “Click here for more information on the Virgo experiment and its science.” to find that the link is broken. “page not found” “There is no offer for the moment, stay tuned” I am looking at the O3a data at https://www.gw-openscience.org/archive/links/O3a_16KHZ_R1/V1/1238166018/1253977218/simple/ I can download it and read it

https://iopscience.iop.org/article/10.1088/1361-6382/ab685e Dear HotJar and IOP Readers, Your questions are too specific. I came here because of a search on Google for gravitational waves software, particularly how the signal on the two arms of each detector is extracted from the single interference strain data. Now your articles are all in text and pictures, so I have
