... But there also exists a practical angle: in a world increasingly dependent on electricity and electronics, the "space weather" outside the atmosphere can have serious effects, in particular on human communications.

... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...

... Research . Projects . ... The name of the project APEX is a reduction from words " Active Plasma Experiments " . The core of the project are active experiments with injection of electron and (or) plasma beams from a board of the satellite with simultaneous registration of the phenomena, produced by interaction of injected beam with background plasma. ... Active experiments utilise modulated electron beam accelerator and source of modulated xenon plasma beam on the main spacecraft APEX. ...

After fragments of the Vortex sleeves separated, whirlwinds of second and third orders ("NC" - new micro-vortex) were generated- future planet cores and their satellites - all of them developing independently, governed by the common laws of development of cosmogenic vortexes. ... Our planet's core today is comprised of considerably deteriorated cosmogenic vortex; consequently, the Earth has a moderated magnetic field. ...

... The necessity of simultaneous access to one communication channel by many users, e.g., in satellite communication systems or cellular telephony, has led to the development of the corresponding standards: FDMA (Frequency Division Multiple Access) and TDMA (Frequency Division Multiple Access). ... There is a number of ideas for chaotic signal applications in multiple-access systems, but as a rule, chaotic signals are used there only as efficient and versatile means of quasi-noise signal formation. ...

... As seen from the alpha particle testing, the spectrometry performance of the CPS32 is limited by peripheral hits and pixel-to-pixel variability, issues unrelated to radiation effects. ... First, it is important to note that, up to the 10 krad dose tested, the CPS32 remained entirely functional. The dominant total dose effect was an increase in the 25єC dark current of 0.58 nA/cm 2 /krad. ... Thus, for imaging, the dark current FPN is likely to be the main performance limitation. ...
