The paper considers two wideband signal design approaches, namely the tabu search and the genetic algorithm, by the criteria of minimizing the sidelobe levels that is essential in the performance of radar, positioning and other radio electronic systems. Both algorithms are compared in the achieved minimum sidelobe levels as well as calculation time required.

Often designs of modern computing systems shall consider energy consumption problems. One possible solution of these problems was found in self-timed design approach. A self-timed circuit is not bound to specific external and internal conditions this make a design very adaptive to energy control. Performance and energy consumption mostly depends on value of supply voltage. A self-timed circuit can operate under ultra-low-supply-voltage therefore, it take very important part in Green computing. Obviously, the same problems appear in high reliable designs of digital devices especially in computing systems for critical application fields such as aerospace microelectronics. Advanced approach to design of energy-aware & naturally reliable computing is described and simulation results are presented.

In this paper, a PWM control strategy of SRM is briefly introduced at first, and then there follows the analysis of ideal flux model by that strategy. An excellent and reliable driver circuit is strongly needed to maintain a normal operation of SRM, and IR2110 is a good choice to ensure accurate switching operation of power electronic devices. A new form of peripheral circuit of IR2110 is suggested with a special charge loop of bootstrap capacitor, which can provide faultless output of trigger switching signals. No doubt, precise flux model demands an exact value of winding resistance and less deviation in integral circuit. Therefore, a newly flux-detecting circuit is eventually proposed to guarantee a better performance of linkage detection.

The paper discusses the impact of electric vehicles on household electric energy consumption. The estimation of daily and annual energy demand of an electric vehicle from an average household is investigated and expressed as the probability of energy required to charge the vehicle battery. A variety of scenarios of electric vehicles' performance for present day and future were analysed using a Matlab simulation to estimate the energy demand. The data used for the simulation are based on UK travel patterns and the National Travel Survey. The results demonstrate that, despite of significant increase of electric vehicles in future, the estimated energy demand by the vehicles from households will be reduced due to increase of the number of charging stations in other locations.

The present paper describes the framework for creating data mining algorithms from thread-safe functional blocks. This framework requirements decomposition of algorithms into independently functioning blocks. These blocks must have unified interfaces and implement pure functions. The framework allows create new data mining algorithms from existing blocks and improves the existing algorithms by optimizing single blocks or the whole structure of the algorithms. This becomes possible due to a number of important properties such as thread-safety inherent in pure functions and hence functional blocks.

Color filter array (CFA) used in CCD and CMOS-sensor to acquire color images determinate the end quality of the image. In this paper the question of the requirements for the CFA to provide both high sensitivity and resolution is discussed. By optimizing the key parameters of the CFA new filters are obtained. The computer simulation proved that proposed CFA outperform known CFA by meanings of objective and subjective image quality.

The present paper discusses radio monitoring tasks and their solution using DFT-modulated filter banks. Filter bank software-hardware implementations are studied on the basis of Central Processing Unit (CPU) and Compute Unified Device Architecture (CUDA) with the use of Graphics Processing Unit (GPU). It is shown that CUDA technology is efficient for processing large datasets and outperforms computational results on CPU. The paper also considers signal classification in real time for different signal-to-noise ratios using a binary tree together with the iterative AdaBoost technique. Experiments show that it is possible to reach the total classification error of 10% for signals handled in radio monitoring tasks.

The object of the research is a modified Bloom filter with counters representing the probabilistic data structure that contains information about the items in a data store. As a result of filter operation false-negative responses are excluded, however occurrence of false-positives is possible. The system is developed in Java using jCuda libraries to parallelize the algorithm on GPGPU systems. The article presents the mathematical evaluation of the probability of false-positives for the modified Bloom filter with counters. A statistical analysis has been made for runs with different parameters: number of hash functions, length of the counter, filter size, number of added elements. The article presents corresponding graphs of the probability distribution of false-positives.
