Abstract:In his 1905 special relativity paper, Einstein defined clock synchronization occurs when photon transmissions traverse a distance (or rod) with equal time spans in either direction. With a universal photon speed, he discovered clocks on the ends of a rod moving parallel with uniform velocity cannot be synchronized, but cloc

Abstract:Based on the double exponential distributions of trap states in the channel of the hydrogenated amorphous silicon thin film transistor (a-Si:H TFT), a new extraction method of the threshold voltage for a-Si:H TFTs has been developed. By taking advantage of the conductivity, the expression of the drain current corresponding

Abstract:In two new single n^+(p^+)-p(n)\ X(x)-alloy junction solar cells at 300 K,\ [X(x)\equivCdS_{1-x}{\rm Se}_x, CdS_{1-x}{\rm Te}_x],0\lex\le1, by basing on the same physical model-and-treatment method, as used in our recent works [1, 2], we obtain the highest (or maximal) efficiencies, \eta_{Imax.(IImax.)}, given in the foll

Abstract:In the n^+(p^+)-p(n) crystalline (X\equivGe, GaSb, CdTe or CdSe)-junction solar cells at 300K, due to the effects of impurity size, temperature, heavy doping, and photovoltaic conversion, we show that, with an increasing donor (acceptor)-radius r_{d\left(a\right)}, both the relative dielectric constant and photovoltaic conv

Abstract:The influence of the Coriolis inertial force, generated by orbital and spin motions of distant objects, on the energies of electromagnetic radiation during the exchange of photons between them is shown. The presence of a red or blue spectral shift arising from this influence has been demonstrated, which is fully consistent

Abstract:The physical properties of force diagrams of kinetic macroindentation of materials by the Brinell sphere are studied. Theoretical and experimental substantiation of physical concepts of the function and number of hardness, new analytical methods for analyzing data from the process of kinetic macroindentation. Universal phys

Abstract:The proton magnetic moment is computed by considering its quarks generated currents based in orbit-like circuits created as they are carted along by its hauler spin. Equations are derived for each quark magnetic moment for two possible rotations modes; needed quarks configurations for each rotation mode to obtain the experi

Abstract:Bulgarian Academy of Sciences transformation into experimental research institution during the second half of 20th century has examined briefly. New scientific branches together with new members of Bulgarian Academy of Sciences have shown. Self-made scientific apparatuses and new scientific and applied results have pointed out.

Abstract:A parametric description of the dependence of the average number of prompt neutrons on the mass of fragments ν(A) from the actinides ( ^{235}U and ^{238}U) photofission has been developed for the range of energies of the first chance of fission (from thresholds of (γ,f) reaction to thresholds of (γ,nf) react

Abstract:Nowadays more and more health risks are increasing. Beside the viruses, there are also other particles which have an impact on the human well-being. The so called volatile organic compounds (VOCs) are substances in the air and can be harmful in high concentrations. Therefore, the detection of VOC value is particularly important.
