Communication security is one of many informatics parts which have huge progress. Sensitive data are increasingly used in communication and that's the reason why is security requirement more timely and important. The risk of obtaining data through an attack increases with enhancing the power of today's computers. Paper attention is mainly devoted to sender authentication based on using digital signature and asymmetric encryption via one-way hash function to calculate public and private keys.

Road transport is one of the main inland transport modes providing flexible house to house services for the people all over the world Control of road traffic flows in urban areas in intersections are modelled in this article. Cost of CO2, CO, CH, NOx, PM and value of travel time had been used by the authors in order to estimate the cost of intersection. The article presents assumptions for constructing the controlling model and gives simulation results. Traffic flow parameters, such as traffic flow concentration and traffic flow speed are presented based on real traffic data of Budapest.

Cognitive Infocommunications (CogInfoCom) is an emerging discipline that investigates synergies between infocommunications and the cognitive sciences, with the goal of creating engineering applications in which systems with various levels of cognitive capability are enabled to work together more effectively. While infocommunications deals with the error-free encoding, transmission and decoding of raw data, CogInfoCom aims to transmit information at a higher, conceptual level in a way that appeals to the receiver's cognitive capabilities. Thus, CogInfoCom may have implications for a wide variety of fields in the future, including virtual reality, 3D Internet and Internet of Things. In this paper, we provide a brief, application-oriented overview of the existing background of CogInfoCom, and outline future perspectives for the field.

The main thesis of this paper considers the possibilities and difficulties of switching from hydromechanical engine control to FADEC (digital) engine control. Regarding different specifications and elements in system, possible errors, advantages and disadvantages, each method has its specific properties of behavior in specific environments and applications. When considering our controlled system, the MPM-20 small turbojet engine, it is a challenge to propose functional control system with backups and with slight possibility of errors during or before operation. In this paper we propose methods of backups for specific elements, prestart diagnostics and on-line diagnostics.

In this paper the author proves that efficiency of multi-objective algorithms can be compared to single-objective algorithms for scheduling jobs in grid environment. Algorithms are compared via efficiency of reaching best solutions given by objective function. There are two criteria (computation speed and computation cost) presented in objective function including users weights on those criteria. Single-objective algorithms are represented by genetic algorithm and simulated annealing. Class of multi-objective algorithms is represented by improved strong Pareto evolutionary algorithm (SPEA2) and archived multi-objective simulated annealing (AMOSA). Algorithms are compared with best available results (by setting the best input parameters found) in ten, twenty, forty, sixty, eighty and one hundred second runs for one hundred experiments each.

Space exploration is usual task in multi-robot coordination. There are several methods that are applied to this issue. To address this problem, we propose modification of PSO algorithm which is described in this paper. Beside the fact that in our method a virtual particles are meant to be embedded in a real robots, the main changes, compared to the classical PSO, are in a fitness function and a cognitive component.

The paper presents a theoretical background overview of the digital communication systems and the BPSK modulation and demodulation. The purposed design is the BPSK system. The BPSK modulation and demodulation represents an important modulation technique in terms of signal power. The BPSK system is simulated using Matlab/ Simulink environment and System Generator, a tool from Xilinx used for FPGA design as well as implemented on two Spartan 3E Starter Kit boards. The first board behaves as a modulator and the second as a demodulator. The modulator and demodulator algorithms have been implemented on FPGA using the VHDL language on Xilinx ISE 12.3. The local clock oscillator of the board is 50 Mhz which corresponds with a period of 20 ns. The frequency of the BPSK carrier is 31,250 kHz. Both, the modulator and demodulator, have been designed and simulated and theirs performances were evaluated by measurements.

The use of telecommunication methods for healthcare purposes is nowadays inevitable to provide satisfactory service. This article introduces and investigates the concept of a decision support system using telemedicine solutions, namely supporting the medical staff and the patient to treat diabetes by determining diet plans and monitoring food consumption (focusing on carbohydrate intake). The system's requirements are to support the monitoring of the patient's well-being, making a choice on the right therapy, the identification of deterioration of health and alert before the patient's situation gets worse. After summarizing the currently existing diet planning systems, the current article focuses on the presentation of the preliminary work, an application developed by Healthcare Technologies Knowledge Centre of Budapest University of Technology and Economics and the Dept. of Control Engineering and Information Technology. The article introduces in detail the homecare supporting system which is the base of the application, the next steps of the specification and the existing literature. Along with present tasks the future plans are also presented.

Since the birth of the subsumption architecture (SA) two decades ago, several derivations have been emerged from the original concept. The behavior-based architectures, one of the successors, have been successful to create simple behaviors in a system, resulting more complex behaviors by their interactions. The dynamic behavior network (DBN), introduced in this paper, does not specify a strict hierarchy between the behaviors, however, the stimulus levels and links determinate their actual states in a moment. The dynamic instantiation and destruction of the behaviors make the design and the development of the behaviors easier and the computational resources are utilized more efficiently. The concept of the DBN is presented in this paper, the common and new behavior patterns are examined as well as a practical application based on DBN is described.
