Focal plane array (FPA)-based infrared thermography (IRT) method was used in dynamic regime to investigate the human organism systemic reaction developed in response to a dry heat transient application to a part of body (forearm). The used infrared camera high performance (100 fps) and high temperature sensitivity (of the order of 0.01 °C) enabled high-precision measurement not only of the extremities...
A comparative study of normal human liver ferritin and livers from normal chicken and chicken with Marek disease was made by Mössbauer spectroscopy. Small differences of quadrupole splitting and isomer shift were found for human liver ferritin and chicken liver. Mössbauer parameters for liver from normal chicken and chicken with Marek disease were the same.
The superconductor-ferromagnetic transistors (SFTs) with the SISFIFS structure (where S, I, and F denote a superconductor (Nb), an insulator (AlOx), and a ferromagnetic material (Ni), respectively) are promising for various applications in superconducting electronics. Specifically, as current amplifiers, they can be used as line drivers and cell selectors in cryogenic memory. Here we report on results...
In this work the issues of frequency estimation of a harmonic signal mixed with additive white Gaussian noise and bipolar chaotic impulse interference by the method of maximum likelihood were reviewed. Estimates obtained by both likelihood functions that taking into account and excluding the interference parameters were analyzed. The influence of fluctuation of parameters of the signal and noise on...
In this work there were reviewed the issues of robustness of frequency estimation of harmonic signal mixed with additive Gaussian noise and chaotic impulse interference by the method of maximum likelihood. There were analyzed estimates obtained by both taking into account and excluding the likelihood function of interference parameters. It was investigated the influence of a priori information about...
In many cases one can be faced with situation of unknown and unstable statistical models of signals and interferences. In this paper the nonparametric approach to synthesis of signal detection algorithms is considered in conditions of the nonparametric aprioristic uncertainty of signal and interference situations
The task of the known form signal detection on background of non-correlated normal interference with unknown variance is considered. The invariant to shift and scale parameters algorithm based on order statistics is suggested. The analysis of quality characteristics of the algorithm has been carried out
