Simualtion of electrochemical systems by analyzing impedance spectra

In this work is carried out simulation of electrochemical system: primary transducer - object by analyzing impedance spectra in different frequency ranges and for different concentrations of these objects. On the basis of modeling, the electrochemical processes occurring in the investigated system are interpreted using elements of the higher hierarchical level of construction of bipolar units

Development of Noise Measurements. Part 4. Problems and Methodology

Abstract: Succession of problems in measuring the parameters of noise processes has been settled following the experience of thermal noise study. An effect of uninformative noise signals on the result of measuring integral characteristics and possibility of optimizing the duration of measurement in the input circuit has been scrutinized. The methods of increasing the interference immunity of means of measuring the integral characteristics of noise signals have been analyzed. Copyright © 2013 IFSA

Development of Noise Measurements. Part 5. Miniature Gas Sensors and their Performance

This work is devoted to the study of the impact of fluctuation parameters on forming random error of temperature measurements of environment. That is particular value for gas fire alarm sensors because it facilitates of increase of their data reliability. Random error is demonstrated to increase significantly under the decrease of sensitive element dimensions that, however, is demanded for reduction of sensor thermal inertia constant

Development of Noise Measurements. Part 8. Nanometrology and Nanothermodynamics as its Scientific Basis

A number of nanoobjects information parameters have been studied on basis of which new nanometrology development directions have been displayed. It is shown that the further nanotechnology development must be grounded on the works which moreover simultaneously develop nanometrology principles. The basis of these works is thermodynamics as integral systems of thermodynamical coordinates which are marked out by the noncorrelated impact on objects. Under the transition into nanosphere some separate thermodynamic degrees of freedom are gradually changing because of surface tension forces prevails over gravity forces. The thermodynamics is complicated by taking into account nonlinearity and interrelations of its coordinates and new discovered physical effects

Development of Noise Measurements. Part 7. Coriolis Mass Flowmeter and its Errors

Coriolis mass flowmeter instrumental and dynamic errors are studied. They can be decreased by the thermocouple usage of R or S types instead of Pt100 sensors. The dynamic error analysis shows that it is able to improve the operation accuracy in the dynamic regime and eliminate the initial period of the flowmeter exploitation in the error compensation absence regime. In consequence of the instrumental error consideration the expediency of the differential thermocouples installation with the reduced performance dispersion, lowered by taking into account of local and extensive inhomogeneities as result of technological deviations of wire production

I-T converting element of quantum temperature standard

Possibility of researching the most contemporary measure of temperature on the basis of fundamental physical constants with involvement of the Standard of Electrical Resistance on the basis of Inverse of Conductance Quantum as well as the Standard of Voltage based on the Josephson junctions array is considered. Its realization depends mainly on the operation of unique electronic device, the work of which forms the basis of the transformation of pulses of electrical voltage into the calibrated jumps of temperature. On the one hand it should be super miniature and pass currents of magnitude of order 1 nA, and on the other hand it should perform the functions of active temperature-sensitive element

Development of software and hardware for the method of rehabilitation of patients with obliteration of atherosclerosis of the limb vessels

The theme of the project proposal relates to scientific research in the field of health care and medical technologies on the basis of the further development and implementation of hardware software, smart sensors, the technique of processing, normalizing and applying of information signals for the creation of means for adjusting the physiological state of the human body by the electro stimulation, agreed in real-time mode with cardiac rhythm. Interest in this topic is due to the manifestation of increasing the duration of the active period in the lives of a number of dangerous diseases, which, in the first place, include diseases of the cardiovascular system. Often, the cause of such diseases is age-related changes, as well as non-future behavior and human habits: smoking, lack of physical activity, unhealthy eating and excessive alcohol. Changing behavior, a person can also reduce the risk of cardiovascular disease
