This paper is about modification of data hiding method in executable files. The previous embedding method hides a secret message in an unused space of the executable file. Statistical difference exists between a program code and an embedded message, which makes this embedding method vulnerable to statistical attacks. This paper offers to encode a message before embedding so that the probability distribution of secret message bytes and the program code bytes were indistinguishable. The proposed approach improves robustness of data hiding method to statistical attacks.

In this paper the possibility of nonlinear correction in «D» class power amplifier and in time- proportional automatic control systems (TCS) is considered when tight counter coupling is invalid for stability reasons. With this end in view it is offered to introduce an additional feedback coupling circuit in the scheme via physical model of the main TCS path. Performance evaluation of the suggested correction method is done taking as an example essentially time proportional «D» class amplifier.

This paper considers procedures in output circuit of powerful two-step «D» class amplifiers operating at low clock frequencies [1]. It is shown that because of resonant phenomena due to output capacity of two-step active elements, essential decrease of commutative loss in no no-signal condition is possible. Correlation received allows to determine optimal clock frequency dependent on pulse leading-edge time of output voltage.

A three-channel multi-standard PAL/NTSC video encoder mixed-signal IP core for digital TV and multimedia applications has been designed. The IP core with about 1.56 mm² is proposed to be fabricated using a standard 0.18 µm CMOS technology flow with analog options followed by packaging using plastic QFN-type package. In the first part of the paper, design- and layout-related data are presented.

We describe and experimentally investigate a method to construct forecasting algorithms for
stationary and ergodic processes based on universal measures (or so-called universal data
compressors). Using some geophysical and economical time series as examples, we show that
the precision of thus obtained predictions is higher than that of known methods.

This paper considers the current problems of the existing economical methods to analyze process approach models while developing effective information management systems (IMS). A new method to analyze the effeciency of model's economical aspect is suggested, having no limitations that exist in the rapidly developing Goldratt Theory of constraints. Also, a technology of break-even analysis is examined (The AS IS model) as an instrument implementing this method.
The method and the technology were tested at the company "SOLOS" dealing with the production of bookstand metal constructions.

Spectral-based algorithms of estimating receiving signal parameters in adaptive arrays, particularly the number of sources and direction-of-arrival (DOA) are described in this paper. This paper provides Bartlett and Capon algorithms that are directly dependent upon physical size of the array, MUSIC and ESPRIT algorithms with the resolution capability not limited by the array aperture.

In the present paper we suggest the method of hiding message in the least significant bits of raster images which was complemented and improved by using well-known scheme ±1. In contrast to ±1 method, our scheme codes embedded message under rates of appearing values 0 and 1 in the least significant bits for the purpose of statistic minimum distortion peculiar to empty container. The algorithm of embedding bits in the image matrix is similar to method ±1. Steganalysis of developed algorithm is running and its advantage in comparison to primary one is demonstrated.

This article is devoted to the causative verbs. The category of causative is one of the actual problem in modern linguistics. Today theory of causative has many unsolved questions, though there is enough plenty of scientific jobs devoted to the given theme. The article's author has tried to specify semantics of causative verbs, to give definition to the given group of verbs.
