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

Hello, I was looking at The Thermal Expansion of Pure Metals: Copper, Gold, Aluminum, Nickel, and Iron at https://materialsdata.nist.gov/handle/11256/32 It has a spreadsheet. In the “Au data” sheet There is a temperature 38136. I think that ought to be 381.36. The value for 157 centigrade, 37.3417? Should it be 0.00373417? The value at 34.6 centigrade,

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

Nanofocused x-ray photon correlation spectroscopy – Data link broken thru DOI.org https://journals.aps.org/prresearch/abstract/10.1103/PhysRevResearch.4.L032012 Fivos Perakis, I was reading your article and wanted to look at the data, but the link is broken. And the DOI system form to report the error is also broken. The DOI form appears but accepts no input. In the PDF: “The

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

I’m interested in this research – could you provide the full-text for it? – Richard Collins https://www.researchgate.net/publication/345347726_Infrared_variability_due_to_magnetic_pressure-driven_jets_dust_ejection_and_quasi-puffed-up_inner_rims I found this on Arxiv. ResearchGate is saying “request full text” because they or you have to provide a pointer to the arxiv file. Or you have to manually download it. I am interested in your ideas about

https://www.researchgate.net/publication/353838684 Recommend you change the title to “Can we ever replace the gravitational force model with something more practical, so we control the forces?” Mircea, Did you ever get an answer to your question? Masses with relatively small number of free charges per kilogram can have electrical forces equivalent to the gravitational force.

Electromagnet for Attracting Copper, Aluminum and Non-Ferrous Metals like GOLD! https://www.youtube.com/watch?v=_mQeaKkaEcQ Yes, vary the frequency and measure the force response. A spectrum is easier to use and understand. There should be specific resonances for each kind and shape of material. Electric and magnetic polarization studies of materials have been tried since earliest days, but have
