Characterization of absorption lines of the degraded deoxyribonucleic acid (DNA) in the range of 0.1 - 1 THz measured by terahertz pulsed and continuous spectroscopy. DNA intramolecular vibrations, vibrations of the hydrogen bonds between two strands of DNA and vibrations responsible for the changes in molecular conformation of DNA when dissolved in water through the formation of intermolecular hydrogen bonds were classified.

This paper describes the greatest science theory which connected different electrical and magnetic effects in one harmonious Maxwell's theory. The amazing result of this theory was the proof of electromagnetic waves existence as the basis of all electricity and optics phenomena. Crucial Hertz's and Lebedev's experiments confirmed this discovery. A short overview of radio communication discovery is also given. All this made the Maxwell's electrodynamics as one of the fundamental laws of nature.

The application of wavelet analysis used to model an electric load retrospective data representation is considered. "A trous" algorithm's application substantiation for the wavelet transform realization is adduced. Furthermore, it is shown that this model allows to increase the forecasting system's accuracy without overloading the system with a large amount of additional information.

Electromagnetic stirring of the melt is an effective and powerful method to influence on directional solidification of different metals and alloys. Three-dimensional numerical modelling is needed to predict or optimize the magnetic field used for the melt flow control. In the paper one created electromagnetic model for three-phases rotational stirrer is described. The model was used to investigate the uniformity of the rotational magnetic field in the melt and its sensitivity to the system geometry. The results of investigation are demonstrated by examples. The model was successfully used to design and modify one laboratory three-phases stirring installation.

At the present time network communication is an important issue where erratic human behavior plays a major role, so the problem of network server efficiency analysis comes up. However, traditional models with Poisson arrival jobs flow are not accurate enough for such cases, so G/M/1 or G/G/1 models with non-exponential distribution of inter-arrival times and either exponentially or non-exponentially distributed service time could be an alternative. Here we introduce the Weibull/M/1 and Weibull/Weibull/1 queues - single server queues where inter-arrival time follows Weibull distribution, and service time follows either exponential or Weibull distributions. We found approximate analytical and numerical efficiency estimates for these queuing systems.

It is important to manufacture hermetic structures based on composite materials for space industry. The composite materials are used in production of aircrafts, satellites, space shuttles, coating of thermal insulation of the space probes. Technology and equipment for measuring the helium permeability of the composite materials is described in this study. The apparatus for the helium flux measuring through material is based on a mass spectrometry leak detector. The test composite samples are made from polymers, coated with metals. A vacuum testing chamber was developed for the installation of the sample, its pre-drainage and creating a pressure gradient of helium relative to the outer and inner side of the test object.

It is well known that electromagnetic fields (EMF) are presented or produced on Utilities elements especially distribution feeders (DFs), which due to the demand, these have increased their capacity. However, DFs are operating near of their limits, which have produced an increase in EMF values, being a preoccupation for their possible effects on the human health. In this context, it is necessary to determine EMF values, which are exposed the population in order to guarantee the functioning of Utilities. In this research by using the Quickfield software based on Finite Elements (FE), EMF values on distribution feeders corresponding to three real electrical substations are determined. Furthermore, these simulated values are compared with measured values and reference threshold values suggested by international norms. Results show that the simulation procedure is effective to determine EMF on distribution feeders.

This paper presents electromagnetic forces investigation of variable speed induction motor. Initially electromagnetic forces of induction motor at nonsinusoidal power supply are analyzed. Proposed radial electromagnetic forces math model allows to take into account higher time harmonics of voltage source inverter supply. Then based on analysis of electromagnetic forces spectral content field oriented control scheme of induction motor drive is proposed. A distinctive feature of this scheme is radial electromagnetic forces minimization at any operating point by rotor flux optimization. Experimental examination of proposed scheme by emulating in Matlab shows reducing of radial electromagnetic forces versus conventional field oriented control.

The purpose structure of the Smart Grid within the industrial electric networks is proposed. The most important part of the intelligent systems for continuous control and diagnostics of the power transformers is mentioned. The paper considers functions of the systems for diagnostics of technical state of the high-voltage transformer equipment. Monitoring systems introduced at the power transformers of the shop of the electric networks and transforming substations and of the combined heat and power plant at OJSC Magnitogorsk Iron and Steel Works are described. The module structure of the system is examined. The paper shows temperature trends of the upper oil layers and partial discharges at the high-voltage inputs. It provides an example of preliminary failure localization according to the parameters of the partial discharges. It also sets a challenge to develop methods of the multi-parameter diagnostics which help to localize and identify a failure according to the set of diagnostic features. Economic efficiency of introduction of the technical state monitoring systems is generally estimated.
