The CBSE enables to reduce the time required for the development and testing, to create robust systems. However not all existing component-based software synthesis methods focus on the software quality. There is the need for the method which can ensure software quality (in terms of consistence of specification and implementation) preserving short time required for software development at the same time. The component-based system synthesis method based on the Curry-Howard protocol is presented in this paper as the solution for this problem. Authors presents some implementation details of this method also and argue that the component-based software synthesis problem and the solution can be stated in terms of abstract component model.

This paper intends to give an overview and identifies best practice designs for European feed-in tariffs targeted to support renewable generation. Furthermore, it introduces and compares feed-in premium designs of different European countries. The main purpose of this work is to develop optimal short-term planning models for price taker hydropower producer working in the existing regimes. Those models have to deal with the high level of uncertainty which is the water power introduces into the power system. We intend to provide guidance in decision-making aimed at maximizing the profit. A detailed analysis is made of a simpler reservoir configuration, which indicates that even though the problem is nonlinear, a bang-bang type of control is optimal, where the power stations are operated at maximum rates of flow. Some simple relationships between price and timing of decisions are calculated directly. A numerical algorithm is also developed. The task of a small HPP operation regime is solved for the maximum income within the cases of the known variation of prices at the market. An optimization tool known as generalized reduced gradient method for nonlinear optimization tasks is used to plan hydropower production under uncertainties.

Simultaneous data transmission over multiple paths can improve the performance of wireless ad-hoc network but interference still can be a problem. To avoid data rate degradation due to inter-path interference, smart routing and transmission strategies using smart antennas should be applied. Analytical method is used to determine how efficient application of smart antennas could be to cancel interference. A comparison of different smart antenna types is done revealing strengths and weaknesses both of directional and MIMO wireless ad-hoc networks.

FPGA implementation of a lattice-ladder multilayer perceptron structure together with its training algorithm in a full scale seems attractive, however there is a lack of preliminary results on the choice of implementation architecture. The aim of this investigation was to get insights on the selected neuron model fixed-point architecture (necessary to use word length) and its complexity (required number of LUT and DSP slices and BRAM size) by the evaluation of the reproduced by lattice-ladder neuron accuracy of bandwidth and central frequency as also as output signal normalized mean error. Thus the second order fixed-point normalized lattice-ladder neuron with its training algorithm was implemented in Artix-7 FPGA. The experiments were performed using various bandwidths and word length constrains. In general increase of word length yielded smaller mean errors. However the limited size BRAM used for trigonometric function LUTs was a bottleneck to improve the precision while doubling the number of DSP slices.

The location of the heart beats in ECG signals are easily detectable by QRS detectors. However the quality of the ECG signal may vary considerably over time. There could be various sources of distortions that changes the shape of the ECG signal and makes some parts of the signal not readable. The QRS detector usually finds additional QRS complexes that are actually not present in the ECG signal. Paper presents effective algorithm to reduce the amount of false heart beat detections together with the algorithm to adjust heart beat position in noisy signal according to blood pressure measurements.

The classic boost topology is a good choice for photovoltaics (PV) Maximum Power Point Tracking (MPPT) converters as it has small current ripple on the input. The efficiency is key parameter for PV-sources as it significantly influences solar system total payoff time. As the energy efficiency for classic converters with silicon-based switches is limited by today technology the GaN switches are chosen. The paper contains brief introduction and market research to set the initial tasks for design. The paper contains simulation results on prototype of boost MPPT converter. All the elements being used for model are device models provided by manufacturers. During the research expected efficiency curves are obtained. Design have been modeled with different GaN switch types for better FET choice. The model will be compared to the real prototype in future research.

Optimal coordinated control of diesel generators (DGs) and battery storage system (BSS) was proposed. Basic block scheme of a stand-alone Microgrid was shown. Objective function of optimal fuel consumption at intervals of transient processes was obtained. Objective function takes into account not only the diesel engine characteristics of the fuel consumption, but also efficiency of power converters charge and discharge and BSS charge and discharge efficiency. An example solution for generator HATZ 1D81C was given.

According to World Health Organization data about one billion of people worldwide are disabled people. About one third of these people are people with mobility or movements impairments. First problem is that for that kind people high precision prosthetic devices with neural control and feedback are very expensive. Second problem almost all average price prosthetic devices have visual feedback system which loads user vision. To solve these two problems decided develop prosthetic devices with other kind of feedback systems: thermal, electrical, pressure, vibration...etc. For using vibration feedback system vibration motors must work in wide range of frequency spectrum and produce controlled intensity in every frequency point. Unfortunately nowadays produced vibration motors cannot satisfy these requirements. In this paper represented three possible solutions of vibration devices for prosthetic feedback systems. Loudspeaker motor based system, linear motor based system and combined system. All three systems are modelled in comsoll metaphysics environment. Modelled parameters are flux density and force-frequency dependencies. As result the best candidate for vibration system is simple voice coil motor. It has linear force-frequency spectrum in wide range. Linear motor most have complex control system and have the same results as combined motor.
