An extended method for calculating heat transfer coefficients using programs
for automated analysis of the thermal regime of TRIANA (ASONIKA-T) radio-electronic
equipment for various designs is proposed. Based on the analysis of the obtained
heat transfer coefficients, it is shown how to set realistic values for the convective
heat transfer coefficient in SOLIDWORKS Simulation and other CAE thermal analysis
systems. The possibilities of using the total heat transfer coefficient, taking into account
convection and radiation, to speed up calculations without compromising the accuracy
of the results are demonstrated.

Superconducting properties of metallic micro- and nanowires can be entirely different from those of bulk superconductors. Of particular interest is the nonequilibrium current-induced state of a quasi-one-dimensional superconducting channel. The most interesting phenomenon here is the stepped I–V characteristic, explained by a process known as phase slip center activation. If the origin of such step-like ...

This paper compares the ranging precision of direct time-of-flight (dToF) and non-line-of-sight (NLOS) LiDAR architectures, both using a superconducting nanowire single-photon detector (SNSPD). Both systems operate at 1550 nm with a 50 ps pulsed laser and time-correlated single-photon counting (TCSPC). The dToF configuration achieved approximately 100 µm precision at 10 m, while the NLOS configuration achieved 500 µm precision for ...
