The effect of the volume flow rate of the heat transfer fluid (air) on the thermal parameters of the solar air collector with a single air pass without using fins under the absorbing plate have been investigated experimentally and theoretically. We use a new design of solar air collector which aims to optimize these parameters in the region cited above. Our solar air collector was realized at t...

In this paper we present a new differential logic unit with duplicated functional outputs. The logic functions as well as their inverses are implemented within a single Logic Unit (LU) cell. The hardware overhead for the implementation of the proposed LU is lower than the hardware overhead required for standard LU implemented with standard CMOS logic style. This new implementation is attractive...

The CBM muon detection system is designed to measure muon pairs from the decay of vector mesons (ρ, ω, φ, J/ψ) produced in heavy-ion collisions. At FAIR energies the muon momenta can be rather low, and, therefore, we developed a muon detection concept which a dynamical definition of absorber thickness according to the muon momentum. The actual design of the muon detector system consists of 6 ha...

A practical problem that arises when using acousto-optic modulators sAOMsd to scan the laser frequency is the dependence of the beam diffraction angle on the modulation frequency. Alignment problems with AOM-modulated laser beams can be effectively eliminated by using the AOM in the double-pass configuration, which compensates for beam deflections. On a second pass through the AOM, the beam wit...
