This contribution investigates different coding methods in application to the compression of thermographic images which were captured on-line for an off-line inspection of welding joints. On-line recording of images enables a complete quality checking. The standard coding algorithm JPEG (Joint Photographic Experts Group), a wavelet-based coding scheme and a DPCM-based (differential pulse code modulation) algorithm are compared with regard to the requirements of real-time applications and minimal loss of information.

The paper represents a totally controlled switches based active current rectifier working in a PWM mode vector mathematical model. The active current rectifier has certain advantages of output current management, energy recuperation, supply line power factor management and forming near sinusoidal line currents. The developed model can be used for electric drive vector control system synthesis. The presented approach also can be applied to current source inverter operating mode analysis. Simulation results are presented.

The possibilities and singularities of the use of the maximum likelihood method, for an improvement in the estimation of denominator polynomial factors at reconstruction of object discrete transfer function on noisy estimation of its impulse response, are considered. The application of this method reduces the necessity of a nonlinear algebraic system solution. A special iterative algorithm of solution of the system is proposed, on which each step, the solution of two linear systems is made. In this case the reconstruction error of the required factors is generated by an arbitrary choice of shaping filter transfer function order, and by the iterative character of a nonlinear system solution. The procedure of indirect monitoring of the obtained estimation effectiveness, by means of inspection of indices of centrality, whiteness and normality of generating noise estimation, is proposed.

New technologies and industrial setups, of powdered material heating directly in a plasma column, have appeared with the development of electric furnaces with hollow cathode arc plasma generators. This has essentially improved the efficiency and economics of producing high melting temperature and high activity metals. The electric furnace for tantalum ingot melting is described, and some melting parameters are given.

The ultrasonic and microwave irradiator for treatment of inner cavities, fabricated on the lateral surface of urological metallic tube with embedded piezoceramic plate, is considered. An analytical model for estimation of insonation intensity is developed, and parameters for matching with lossy media are obtained. The developed mathematical model is validated by experiment.

The application of the model of plasma gap for process of low-temperature plasmachemical treatment of units of cathode-ray and photoelectronic devices (CRPhED) is considered. The model allows to consider potential distribution in the gap as similar to potential distribution without plasma. The model gives the possibility to calculate potential on the electrodes, necessary for the quality cleaning of workpieces.
