The results of investigation of spectroscopic dependence of absolute current sensitivity of metal-semiconductor-metal (MSM) photodetector on the basis of GaAs, compensated Cr, with interdigitated contact electrodes are presented. Measuring was carry out at a uninterrupted exposure over the range of wave lengths 350–1100 nm at a various bias voltage on a photodetector. It is ascertained, that photodetector have high sensitivity in both fields — fundamental absorption, and in the impurity absorption. It is shown, that at energy of quanta greater 2.1eV and a bias voltage above 3V the effect of intrinsic amplification is watched.

In this paper is introduced the Orbcomm system as a wide area packet switched and global two-way data transfer network providing satellite communication, tracking, monitoring and logistics services between mobile, remote, semi fixed or fixed Subscriber Communication Units (SCU) in Mobile Satellite Communications (MSC) and Gateway Earth Stations (GES) or Gateway Control Centres (GCC) accomplished via LEO satellites and Network Control Centres (NCC). Orbcomm Global, L.P., from Dulles, Virginia, USA equally owned by Teleglobe and the Orbital Sciences Corporation, provides global services via the world's first LEO satellite-based data and messaging communications system. The US Federal Communications Commission (FCC) granted Orbcomm a commercial license in October 1994 and the Commercial service began in 1998. Orbital Sciences was the prime contractor for the design project of Orbcomm satellites. The Company owns and operates a network consisting in 36 Little LEO satellites and several GES deployed around the world, connecting small, low-power and commercially proven SCU terminals to private and public networks, including the Internet. Orbcomm delivers information to and from virtually anywhere in the world on a nearly real-time basis to the Terrestrial Telecommunication Network (TTN). The Orbcomm ground segment and subscriber transmitters (Tx) that provide a continuous 4.8 to even 9.6 Kb/s stream of downlink packet data to the receivers (Rx), and vice versa.

In this paper, a modified Kalman filter is proposed to estimate speed. At first, the influence of the magnetic saturation is taken into account in the modelling. In the second part, the direct torque control (DTC) is elaborated; the control of the speed loop is ensured by an IP controller, the flux and the torque are estimated from source voltages and measured currents. The last part of this work is devoted to the operating system without mechanical sensor, using a Kalman filter as a speed observer. Simulation results are presented to verify the effectiveness of the proposed approach.

This paper presents a method to design a predictive controller for a single Inverted Pendulum (SIP) system. The design goal is to balance the pendulum in the inverted position in the presence of parameter variations and measurement white noise Using linearization technique, the model of SIP system is transformed to a linear polytopic system. Since we need to estimation of states, a new robust model predictive control (RMPC) strategy is developed for this system with considering white measurement noise. Simulation results are presented to show the robustness of the closed-loop system against parameter variations and measurement white noise.

In this paper the results of multichannel GaAs detectors testing in integral mode are presented. It is shown that for x-ray quanta at the energy range 40–75 keV and exposure dose more than 1,5 mR the noise characteristics of the detectors are mostly depends on photon noise. It is experimentally proved that negative potential on irradiated contact and an inclination of detectors at a small angle to a direction of falling of radiation allow to increase sensitivity of detectors considerably.

Genetic algorithms (GA) are stochastic search procedures which have been used for solving many complex optimization problems. It is obvious that GA collect and exploit some statistical information about the search space, but this information isn't processed in explicit way. In this paper, we consider GA with binary representation and its explicit statistics in a form of probability distribution of unit-values. The binary GA convergence property is discussed and a new convergence prediction method is proposed. The results of the prediction algorithm effectiveness investigation over the set of complex continuous and discrete deceptive problems are presented.
