Application of adaptive classification of tensotremorograms for revealing the pathological states of human motor control system

In this paper the adaptive binary classifier is applied for the classification of the tensotremorogramm (TTG) time series. The idea is to reveal pathological states of human motor control system. Adaptive binary classifier being a new type of trained classifiers can be trained on the data for healthy subjects. Then the trained classifier can be used for the examinees division into healthy and sick patients. It is shown, that the trained adaptive binary classifier is able to classify the patients with acceptable accuracy. Other method of classification-Neural Clouds-has also been used. The comparison both methods has been done.     

A Millimetre-Wave Cuboid Solid Immersion Lens with Intensity-Enhanced Amplitude Mask Apodization

Photonic jet is a narrow, highly intensive, weak-diverging beam propagating into a background medium and can be produced by a cuboid solid immersion lens (SIL) in both transmission and reflection modes. Amplitude mask apodization is an optical method to further improve the spatial resolution of a SIL imaging system via reduction of waist size of photonic jet, but always leading to intensity loss due to central masking of the incoming plane wave. In this letter, we report a particularly sized millimetre-wave cuboid SIL with the intensity-enhanced amplitude mask apodization for the first time. It is able to simultaneously deliver extra intensity enhancement and waist narrowing to the produced photonic jet. Both numerical simulation and experimental verification of the intensity-enhanced apodization effect are demonstrated using a copper-masked Teflon cuboid SIL with 22-mm side length under radiation of a plane wave with 8-mm wavelength. Peak intensity enhancement and the lateral resolution of the optical system increase by about 36.0% and 36.4% in this approach, respectively.     

A high-temperature accessory for measurements of the spectral characteristics of thermoluminescence

A high-temperature accessory for a commercial fluorescence spectrometer, which allows performing luminescent studies of solid samples in the range up to 773 K, is described. The modes of linear heating with rates of 0.1–10 K/s, temperature control with an accuracy of <0.5 K, and an arbitrary temperaturetime profile were realized. The operation of a Perkin Elmer LS55 spectrometer at high temperatures was demonstrated by the example of investigating the spectral and kinetic regularities of thermoluminescence in hexagonal boron nitride using the developed module.     

Mechanisms of the self-propagating high-temperature synthesis, phase composition, and magnetic properties of complex oxide ferrimagnets with M structure

Mechanisms of the combustion of reagent mixtures that form complex oxide ferrimagnets (hexaferrites with M structure) are investigated. The phase composition of the end product is found, depending on technological conditions that include self-propagating high-temperature synthesis with preliminary mechanical activation and/or subsequent ferritization. The basic static and dynamic magnetic properties of an end product synthesized in the optimum mode are determined. An energy-saving technique for manufacturing hexaferrites with M structure, making it possible to lower production costs substantially, is proposed.     

Mathematical description of a boiler house operating jointly with a wind power plant and heat storage

A heat supply system is considered that contains, along with a boiler house, a wind power plant and heat storage. Methodical approaches for determining the operating modes of the heat storage jointly with the wind power plant are developed. A mathematical model of the heat storage is obtained using which a numerical experiment can be carried out. Results determining the positive energy effect from using a system combining a wind power plant and heat storage are presented.     

Magnetic properties and microstructure of SHS-Produced co-containing hexaferrites of the Me<Subscript>2</Subscript>W system

BaCo_{2 − x} Zn _x Fe₁₆O₂₇ hexaferrite powders were prepared by mechanoactivated SHS. The ferrites were characterized by XRD and phase analyses. The values of specific saturation magnetization, field of magnetocrystalline anisotropy, spin reorientation transition, and Curie’s temperatures were derived from static and dynamic measurements of respective magnetic properties. The spectra of magnetic permeability and dielectric permittivity were measured within the microwave range.     

Estimation of possible participation of wind power installations in compensation of heating demands

Application of wind power installations for heat supply of consumers in northern regions with enhanced potential of wind energy is considered. The influence of wind on heat consumption regimes is analyzed. Possible participation of wind power installations in heat supply of consumers on the Barents seashore is estimated.     

Reconstruction of the temperature field in a solid from a limited number of measurements

We have obtained extrapolation formulas for calculating the temperatures, temperature gradients, and heat fluxes in a solid heated by a varying thermal flux from the results of temperature measurements at two points. The applicability limits and errors of the proposed formulas have been investigated.Translated from Inzhenerno-Fizicheskii Zhurnal, Vol. 17, No. 3, pp. 553–558, September, 1969.
