The continually increasing population, the rising economic activity and the permanent race for the rise of economic prosperity, led us to the increase of motorisation. Transportation sector has an important role, because it is not only using the lacking fossil energy sources and polluting the environment, but because of our social and economic structure it is the sector that can hardly change because of the big social resistance. One of the substantial preconditions for the change into an environmental friendly, sustainable system is correct data provision to the regulator (quality and quantity as well). One way for reduction of transport related environmental pollution is to give right price signal to the users with internalisation of transport related external costs. In our article we tried to examine the route choice behaviour in Hungary focusing on toll roads. Our aim in this paper is to analyze the correlation of control possibilities of such econometric phenomena with mathematic tools.

This paper presents a novel method for control cooperating robots without any explicit communication line. We have proposed a fuzzy communication philosophy and implementation technique, where the codebooks are built up by signatures. Fuzzy signatures are used as complex state description method for intention guessing and action selection. Finally some real scenarios of autonomous mobile robot cooperation are presented.

This paper presets a new algorithm for nonlinear distortion cancellation and channel re-estimation in an iterative manner. Whereas in practical OFDM systems, in which nonlinear amplifiers are used, data as well as pilot symbols are nonlinearly distorted. As perfect channel state information is often assumed in many works and papers, the effect of nonlinear distortion on pilot symbols is often not accounted for, and only data symbols are considered. However, as pilot symbols are used to obtain channel state information, distortion inflicted to pilot symbols by nonlinear amplification is of great importance, and for this reason should be accounted for. To address this issue, simple algorithm will be introduced for joint data recovery and channel re-estimation in an iterative manner. This algorithm iteratively estimates nonlinear distortion and then uses it to compensate this nonlinear distortion present at data and pilot symbols, which are then used for subsequent and more precise channel re-estimation. As it is shown in this paper, proposed algorithm can be used to reduce nonlinear distortions even in a situation, when highly nonlinear amplifiers are applied.

The programmable analog circuit (field-programmable analog array), as a new component and a new technology appeared some twenty years ago. As a result of the continuous development, these devices programmed on a digital surface make an analog circuit topology with component parameters also given as programmable. FPAAs can be used for the realization of different functional units, circuits, circuit elements. The advantage of FPAAs in the field of reconfigurable circuit planning is significant. It is beneficial in self-developing circuit applications. In microcontroller environment we can use these FPAA circuit in different useful application as an predictive-, and a characteristic prediction circuit solution. We describe a control solution of an industrial machine control as a demonstration of applicability of microcontroller and FPAA circuit cooperation.

With the newest medical researches and studies increase equipment's rate of health centers. By contrast to it, any parts of medicine in SR and abroad don't utilize all actual knowledge's and possibilities. One of this is the measurement of intra-abdominal pressure in critical ill patients. From the results of analysis the most often intra-abdominal pressure measurement is via bladder. This is not invasive method with high significant weight. The measurement techniques what are in present time usually used does not meet criteria for modern diagnostic methods. This paper describes the verification of measuring system for intra-abdominal pressure measurement. The measuring system is the basic part of proposal device for automated measurement of intra-abdominal pressure.

Pulse Wave Analysis is a new technique to determine age and disease related changes in pulse wave morphology. We developed a software tool to extract information from an approximately one minute long data flow registered by photoplethysmography. The results of the computation, presented in both numerical and graphical forms, provide diagnostic value in assessing vascular health.

Software product lines are a successful approach to software reuse. To a significant extent, the development of product lines is complicated by crosscutting concerns. This is especially true for product line configuration. Aspect-oriented programming can often help to develop product lines more effectively, but this is not always so. This paper shows it is possible to sublimate the expert knowledge about using aspect-oriented programming in product line development in the form of independently applicable guidelines by proposing an approach to expressing such guidelines. A complete guideline entitled Implementing Mandatory Features with no Crosscutting Concerns is presented as an example. The guidelines have been evaluated in a product line case study that confirmed their applicability. The results of this study obtained by the application of a number of metrics are provided and discussed in the paper.

Paper is focused at connections between human patterns, social care systems and mainstream technologies. Ambient technology should provide higher level of autonomy, security and quality of life. This means usability of those services easy and effective to use, comfortable, and easy to operate with. Important point of assistive support based on mainstream systems are features of design for all. Services are presented at FU Laboratory at Technical university of Kosice as result of MonAMI project. The target groups are seniors and persons with disabilities living alone or in sheltered households.

This paper deals with some methods of artificial intelligence which are applicable and useable in an engine control. This research is directed towards the jet engine application, specifically on the Saphir-5 engine. The main goal of the work is to substitute current control system with the system FADEC coupled with an expert system which should introduce some level of intelligence in the control circuit.

In this paper, imaging method for moving target tracking by a multistatic ultra-wideband radar system is described. The task of moving target tracking consists in estimation of a target trajectory based on processing of raw radar data obtained from all receiving channels of a radar system. Then, the imaging method applied for target tracking consists of such signal processing phases as raw radar data pre-processing, background subtraction, fusion of the data obtained by receiving antennas of a radar, detection, localization and tracking itself. The performance of the imaging method described in this paper is demonstrated by signal processing obtained by M-sequence UWB radar for a scenario represented by through wall tracking of a single moving target. The obtained results confirm the excellent performance of the discussed method.
