In this paper, the geosteering technology of drilling tool, relatively bottom of oil horizon in oil and gas reservoir was proposed. A theoretical model of borehole logging tool, transmitting and receiving ultra-wideband (UWB) electromagnetic pulses was proposed. The pulsed voltage at the output of the receiving antenna of borehole electromagnetic logging tool (BELT), located near the oil-water contact (OWC) was simulated, used experimentally tasted models of complex dielectric permittivity (CDP) of oil-saturated rock. The principal possibility of detecting the reflected pulse from transition layer which separates the oil-saturated rock from water-saturated rock and determine the distance to OWC was shown.

In this paper, we propose a subspace algorithm for the identification of linear-time-invariant discrete-time systems with more outputs than inputs from measured power spectrum data. The proposed identification algorithm is interpolatory and strongly consistent when the corruptions in the spectrum measurements have a bounded covariance function. Asymptotic performance of the proposed algorithm is illustrated by means of a numerical example.

Due to the randomness of the biochemical process at the molecular level, genetic regulatory networks are inherently noisy. They are also subjected to extrinsic noises which are external to the gene expression. In this paper, we consider genetic regulatory networks with non-vanishing additive noises and investigate stochastic asymptotic boundedness of them. By using itô's differential formula and Lyapunov-Krasovskii functional, we derive sufficient conditions so that system solution be bounded (in expectation) by a monotone function of the supremum of the covariance of the noise. All these conditions are presented in terms of linear matrix inequalities (LMIs). Finally, Numerical example illustrates the usefulness and applicability of the proposed conditions.

Thin films of gallium oxide have been deposited in vacuum on the GaAs substrates by thermal evaporation of powder Ga2O3. The capacity-voltage and siemens-voltage characteristic of Ga2O3-GaAs structures were investigated. It was shown that the greater the action time of high-temperature treatment in the flow of inactive gas (Ar), the lower the capacitance of the dielectric and thus lower permittivity (ε) of Ga2O3. This phenomenon can be explained by the change structure of Ga2O3 and its reconfiguration in the more conductive phase with a small quantity of the dielectric constant. The amount of surface-states density at the interface of annealed MOS structures decreases to 1·1012 cm−2 eV−1.

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.

Arc antenna arrays for high frequency band are examined. The optimal length of log-periodic array elements is discussed. The expression for array dimensions are derived which ensure constant beam width within frequency range. It is shown by means of computational modeling that for keeping of constant beam width the length of element should be extended.
