International Conference on Information technology Interfaces

作者： Z. Baracskai J. Velencei Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

Knowledge has become the most important producer of wealth in society and in organizations. Corporate success in today's economy comes from being able to acquire, codify, and transfer knowledge more effectively and with greater speed. Important aspect of knowledge management is extraction of the personal tacit knowledge and putting it into words and order, so that others can attain it and use it. Big enterprises need concept maps. In places where the knowledge workers are familiar it is a waste of money. Where more than 200 people use knowledge it is very time demanding to find requisite knowledge

International Symposium on Intelligent Systems and Informatics (SISY)

作者： J. Gati Gy. Kartyas Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

By the development of communication in computer systems, development and application of Internet mediated teaching systems in the communication intensive higher education one of the main concerns in applied informatics. As these applications became more complex and by increased demand for better utilization of computer technology, direction of development changed to replace the conventional documentation style systems by more advanced model based systems. The authors made an analysis on one of these attempts from the point of view application of model based virtual higher education programs in the practice of engineering education. In this paper, representative issues and methods are introduced and discussed including versatile course based on student profile, definition and constraining of courses, topics and procedures, and extension to industrial modeling system.

Power Tech Conference

作者： P. Handl Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

Nowadays environmental aspects play a determining role in overhead line designing. The compaction of the transmission lines means a reduction of the dimensions of the towers and the length of the insulators, so the lightning and switching withstand voltage of the insulator configuration of a compact line can be lower, than that of a conventional line. The behaviour of the insulators stressed by standard waves is known usually. On the other hand, the voltage stress of the insulators differs from the standard 1.2/50 /spl mu/s waveform considering a real line, because of the reflections on the grounding, on the neighbouring towers etc. In the paper simulation results will be published, taking into account also the difference between the real wave shapes and the standard one. To obtain such results, the calculation of the disruptive effect (DE) has been implemented to estimate the withstand of the insulators to nonstandard voltage stress and on the other hand to determine the probability of a back-flashover initiated by lightning strokes. To find the optimal number and location of line arresters or find an other way to reduce the number of back-flashover a detailed analysis of the processes initiated by lightning strokes is required.

International Conference on Systems, Signals and Image Processing, IWSSIP

作者： Lajos Varga Zsolt Kollár Péter Horváth Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

This paper presents a modified Staggered MultiTone (SMT) receiver structure tailored to cognitive radio applications. SMT schemes employing Fast Fourier Transform (FFT) in the receiver for demodulation are discussed in the first part. The second part deals with Recursive Discrete Fourier Transform (R-DFT) originating from measurement systems. The recursive structure is suggested as an alternative to FFT for demodulation and spectral sensing. The paper concludes with a discussion of the advantages of the proposed receiver architecture especially in cognitive radio applications, and the investigation of the required signal processing complexity.

IEEE Region 8 International Symposium on Video/Image Processing and Multimedia Communications (EURASIP)

作者： J. Levendovszky L. Kovacs G. Jeney Department of Telecommunications Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

The paper is concerned with developing novel multiuser detection algorithms. The main stress is on blind decorrelation of weakly stationary processes which can successfully combat multiuser interference (MUI) and intersymbol interference (ISI). The detector architecture includes an adaptive channel identifier (capable of blind decorrelation), followed by a stochastic Hopfield net which performs the task of multiuser detection. The key contribution to mobile communication lies in two factors: (i) blind decorrelation which can identify the channel even in the case of fading; (ii) the use of the stochastic Hopfield net which can guarantee good performance due to its ability to reach the global minimum of the associated quadratic form. The proposed detector structure is proven to be superior to the RAKE or Viterbi receivers. The results are demonstrated by simulations as well.

International Conference on Microwaves, Radar and Wireless Communications

作者： Attila Zolomy Tibor Toro Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

In case of integrated digital radio chips devoted to low cost, licence free short range radio systems the necessary bill of material and the battery life are one of the most important issues. The targeted RF power level determines whether a low or a high Q output architecture (output driver stage+optional matching+antenna) gives better result. It is shown that in case of the most commonly used radiated power ranges (-20...+10 dBm) for this radios, the high impedance configuration is advantageous. The high Q configuration is applied in a general purpose 0.6 mum BiCMOS transmitter chip operating in the 315, 434, 868 and 915 MHz bands. Novell printed high Q antenna topologies ad matching network are presented as well.

IEEE Design and Diagnostics of Electronic Circuits and Systems (DDECS)

作者： Andras Timar Marta Rencz Department of Electron Devices Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

In the past few decades, medical and biological researches gained more and more attention. The ever-growing need for such researches caused many medical applications to develop. Collecting data from a living human body is a complex task and needs circumspection. In this paper, specific issues of the most important part of such a data acquisition system is presented, the design of a low pass filter. The major issue to overcome in the design of a system that is aimed at being built into the human body is creating large value capacitances needed to the realization of filters for the specific application. After presenting the special requirements for low pass filters for medical applications the method of creating large capacitors is presented in details in the paper.

International Conference on Transparent Optical Networks

作者： P. Szegedi Budapest University슠of슠Technology슠and슠Economics Budapest Hungary

The paper is motivated by changes experienced in the fields of traffic types and volumes, network structures and market trends; it concentrates on the metro core. Assuming a possible RPR-WDM network architecture, a cost-effective way is proposed for increasing network load without increasing the electrical components of the network nodes, so without increasing dramatically the provider's capex. Based on flexible optical devices, an automatic logical node reordering process to improve the RPR (resilient packet ring) layer performance is proposed.

International Conference on Software, Telecommunications and Computer Networks (SoftCOM)

作者： Gabor Nemeth Gabor Arpad Nemeth Communication Department Budapest University슠of슠Technology슠and슠Economics Hungary Department of Telecommunications and Media Informatics Budapest University슠of슠Technology슠and슠Economics Hungary

The previously separate fields of computing and communications are converging rapidly. Besides, the intelligence aspects necessitate the integration of formerly separate various processing modes. The emerging intelligent network aims to provide advanced services, extending well beyond the traditional voice, data transfer and computing services, handling intelligence aspects of possibly imprecise and inconsistent information as well. These services are offered on dynamically varying network structures and processing nodes for arbitrary number of users in a transparent way. The widely used design models are based on separate problem classes, thus their extension to these problems is very difficult, if possible at all. A generic model for the clarification of the issues involved and determining the theoretical limitations is investigated, thus forming a starting point for various design models with precisely known limitations.
