A new digital technique for objective differential diagnosis of the septic process severity was developed and experimentally tested by phase mapping of microscopic images of histological sections of polycrystalline internal organs and blood films of laboratory rats. the results of statistical analysis of histological sections of the internal organs of rats from control group 1 and research groups 2 to 4 with different severity of septic pathology are presented.
Bases of construction of optoimmittance logic are formulated, marketability’s of optoimmittance logical elements are considered, that will allow extending functional possibilities and improving the technical parameters of different informative devices. The classification, technical implementation, the basic parameters and characteristics of optoimmitance logical elements are presented. The speed of optoimmittance logical elements is analyzed.
Glitches appear in digital-to-analog converters and lead to significant limitations of conversion accuracy and speed, which is critical for DAC and limits their usage, especially in the direct digital synthesis systems. This paper researches the causes, the specificity of the appearance of glitches in DAC and the possibility of using weight redundancy in order to reduce glitches in DAC. There had been suggested and analyzed the mathematical model of glitches in DAC with weight redundancy. There had also been proved that glitch amplitude is significantly influenced by the value of the voltage control of the DAC and the parasitic capacities of the digital keys. There had been shown that the attenuation time (duration) of the glitch is significantly influenced by the value of load resistance. The paper shows the expediency of using the DAC based on redundant positional number systems including Fibonacci p-codes. The simulation results prove that with the increase of the parameter p, the characteristics of glitch are significantly improved in comparison with the classical binary system, namely the amplitude and the attenuation time of glitch decrease.
