Signal Decomposition and Feature Extraction Techniques: Application to Seismic Mitigation of Vibration-sensitive Eq Shieh-Kung Huang, This is very informative. I will only suggest a few things. Vibration isolation is now needed for buildings, as an integral part of energy harvesting, to allow orders of magnitude improvement in seismometers and gravimeters, and for gravitational wave

I have learned its limitations and by careful adjustment to the way I write, I can get it go generate words in the directions I want to go. I realized most people cannot absorb

Accelerometers and gradiometers get better at higher frequencies, use the Internet to multiply capabilities many fold https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering These “updates” are just things I think are important to remember, and what I can find time and energy to write down. If you see something you disagree with, write me or make a comment. I got a

https://www.researchgate.net/project/Solar-System-Gravimetry-and-Gravitational-Engineering/ Calibrating all gravitational sensors into a single imaging array: I was thinking about this some more. The gravitational potential from the sun and moon changes significantly during the year and over the course of the day. And the absolute values (for the usual network few hundred samples per second and slower) change slowly. Your

https://www.researchgate.net/publication/359389325_ON_THE_NORMAL_HEIGHT_DIFFERENCES_DETERMINATION_FROM_GEOPOTENTIAL_DIFFERENCES/comments Using real time comparisons via electromagnetic signals gets more complicated. Trying to use high speed storage of the signals gets memory intensive and expensive. As much of the data is nearly the same. The reason I used the vector tidal gravity signals for calibration and standardization is that each location can compare to

Low Cost, Time-of-Flight Gravimeter Arrays https://hackaday.io/project/164550-low-cost-time-of-flight-gravimeter-arrays More information posted at ResearchGate on 3 axis gravimeters RichardCollins • 07/19/2022 at 17:15 • 0 comments My main “job” is the Internet Foundation, so I am constantly monitoring global issues, methods and activities on the Internet. But I have a heart for research groups and gravitational noise detector

The Planck Temperature – Absolute Hot: What is the hottest temperature possible https://www.youtube.com/watch?v=ofzlBP6_5iw If you had a $Thank button, I would have sent you a donation to encourage you to keep going and work harder. You have the right kind of curiosity, but you need to keep digging and read harder papers. Tone down “strange”

This intro added 10 Jul 2022 in update to “Solar System Gravimetry and Gravitational Engineering ” Comment on “MegaAmpere to MegaGauss” – Using laser fluctuations to measure gravitational potential turbulence To generate intense fields to control the motion of matter. To emulate gravitational acceleration so precisely there is almost no error in position or other

For more than 50 years I have been trying to understand the gravitational potential. I used it for orbit determinations when I worked at my first job at the CIA, then later worked on a NASA project to determine the geopotential itself using satellite orbits and measurements to solve for the shape and properties of
