The ionosphere is exposed to forcing from below due to gravitational, geomagnetic and seismic activities, and above due to solar wind.These forces cause some medium and large scale irregularities and disturbances into the upper atmosphere and ionosphere.Some of these disturbances occur in the form of wave-like oscillations in the ionosphere which p
The modelling of an expert system for diagnosing the operational status of a diesel genset represents the final stage of the research undertaken so far on military gensets.The research was undertaken in several stages on a large number of gensets, and the results obtained at specific research stages were published at scientific-expert conferences.F
Abstract An ideal blackbody absorbs all light impinging on it, and it radiates electromagnetic waves with a broad spectrum that depends only on the temperature.Conversely, a white object is characterized by a finite reflectance to visible light, hence being the opposite of a blackbody.Challenging this concept, here we find that Stems various substa
