_____________________________________________________________________________ Ransomware has been widely touted as a highly dangerous, sophisticated and destructive breed of malware. And some of it certainly is. But based on recent academic research into constraints, commonalities and advancements across 15 ransomware families, many of the ransomware families in the wild today are not necessar...

The paper reviews modern gravimeters of aviation gravimetric systems, their design and principle operation. Their advantages disadvantages, features functioning processing the received data are analyzed. It is shown that high-precision measurements gravitational acceleration (g) extremely relevant necessary for many fields science technology. main characteristics known given. has been establish...

Low noise underground environments offer conditions allowing to assess ultimate performance of high sensitivity sensors such as accelerometers, gyrometers, seismometers... Such facilities are for instance ideal for observing the tiny signals of interest for geophysical studies. Laboratoire Souterrain à Bas Bruit (LSBB) in which we have installed our cold atom gravimeter, provides such an enviro...

Gravimeters are used to measure density anomalies under the ground. They are applied in many different fields from volcanology to oil and gas exploration, but present commercial systems are costly and massive. A new type of gravity sensor has been developed that utilises the same fabrication methods as those used to make mobile phone accelerometers. In this study, we describe the first results ...
