Decision support system for evaluating existing apartment buildings based on fuzzy signatures

Gergely Molnarka László T. Kóczy

Publication Name: International Journal of Computers Communications and Control

Publication Date: 2011-01-01

Volume: 6

Issue: 3

Page Range: 442-457

Description:

In historical district at European cities it is a major problem how to take decision on renovating or replacing existing buildings. This problem is imminent in Budapest (Hungary) in many traditional districts such as the Ferencváros district where we selected a compound area for further examination. By financial aid for the renovation of these buildings which awarded by Municipal Assembly of this district in question there is much uncertainty and confusion concerning how to decide whether or not and how to reconstruct a building where new private owners apply for support. In this paper we propose a formal evaluation method based on fuzzy signature rule bases (the formal being a special case of L-fuzzy object). Using the available expert knowledge we propose a fuzzy signature model including relevance weights and weighted aggregations for each node and parent node, respectively, so that as a result a single membership value may be calculated for each building in question. Linguistic labels for decision (such as worthless, average, highly valuable, etc.) are generated from the values thus obtained. Such linguistic calculations might be of help for the Municipal Assembly awarding financial support. A complete example wit 26 buildings is presented. © 2006-2011 by CCC Publications.

Continuity and Discontinuity in the Interaction of Regional and Corporate Cultures: Potsdam (Germany) and Győr (Hungary)

Miklós Losoncz

Publication Name: European Planning Studies

Publication Date: 2011-01-01

Volume: 19

Issue: 11

Page Range: 1995-2008

Description:

The paper compares the specific identical and different features of the relationship and interaction between corporate and regional cultures in Potsdam (Germany), on the one hand, and in Gyo{double acute}r (Hungary), on the other hand, based on the empirical research results obtained in the Corporate Culture and Regional Embeddedness project. The major conclusion is that regional and, to some extent, broadly defined corporate cultures survived the socialist episode of history in both regions to a more pronounced extent than in the rest of the respective countries, thereby representing a high degree of continuity. Although the driving forces were different, embedded in a set of specific factors, the mobilization of this social capital produced a vicious circle after the transition to market economy in both regions, making the adjustment to the new situation more successful than in the other regions. © 2011 Copyright Taylor and Francis Group, LLC.

Transient analysis module from an object oriented electrical circuit designer application

Miklós Kuczmann Éva Katona

Publication Name: Przeglad Elektrotechniczny

Publication Date: 2011-01-01

Volume: 87

Issue: 3

Page Range: 89-92

Description:

The paper deals with a software module, developed by the first Author, from a complex electrical circuit designer application. This analysis module presents the transient response of the designed network to the excitation applied to it. The results can be calculated by some different type ordinary differential equation solvers. The most important aim of this part of the research is creating a new algorithm, which the all different type ordinary differential equation solvers can be used with one algorithm.

Ethical labyrinth in the period of knowledge acquisition and sharing of knowledge management systems

Bencsik Andrea

Publication Name: Problems and Perspectives in Management

Publication Date: 2011-01-01

Volume: 9

Issue: 3

Page Range: 93-99

Description:

To create a knowledge management system within a company is a very demanding goal. Organizations have to satisfy a lot of demands and prerequisites to make an operable system which can support management and which can realize business success. Knowledge management is influenced by organizational culture, by leadership and by people's attitudes - and this can obstruct knowledge acquisition and sharing, or can facilitate business success. It means that the business's ethical questions have to be managed and problems in this area have to be solved. Most companies do not deal with ethical questions. If they do deal with them, ethical problems will be the center of attention only in the external relationships of companies. According to a famous management slogan, "first we have to make order inside the company" (Oakley & Krug, 1997). Internal order will bring along order in external relationships, too. This means that you should make order first in your internal processes, systems and human relationships from the point of view of ethical problems. This paper approaches ethical problems theoretically, which can help in coming up with the creation and actuation of a knowledge management system to continue empirical surveys. These questions will be created at the end of this theoretical paper. On the basis of these questions it will be conducted an empirical survey at some companies. © Andrea Bencsik, 2011.

Active vibration control using DEAP actuator

A. Nagy

Publication Name: Mechatronics Recent Technological and Scientific Advances

Publication Date: 2011-01-01

Volume: Unknown

Issue: Unknown

Page Range: 331-335

Description:

The dielectric electro active polymers actuators (DEAP) have several advantages over the conventional actuators, for example low cost, small weight and silent working. Because of the properties of the polymers, the precise control of this actuator type requires some special considerations. In this paper a dynamic model of a DEAP actuator was created. Additionally a closed loop control of a DEAP actuator in a vibration attenuator application was demonstrated.

Optimal design of a magneto-rheological clutch

Dávid Törocsik P. Horváth

Publication Name: Mechatronics Recent Technological and Scientific Advances

Publication Date: 2011-01-01

Volume: Unknown

Issue: Unknown

Page Range: 89-93

Description:

Appliances using magneto-rheological fluid (MRF) can find application in shock absorbers, brakes and clutches. Until now the spread of MRF clutches was limited by the moderate torque they can transmit. This paper summarizes the factors influencing the torque transmitted. During the design process of a prototype MRF clutch its most important geometric data have been determined by means of simulation of the magnetic circuit.

A kantian pattern of knowledge, the observation representation

Claudiu Pozna Áron Ballagi Radu Emil Precup László T. Kóczy

Publication Name: Siisy 2010 8th IEEE International Symposium on Intelligent Systems and Informatics

Publication Date: 2010-12-30

Volume: Unknown

Issue: Unknown

Page Range: 405-412

Description:

This paper suggests a new pattern of human knowledge. Its execution represents an important stage in the general framework of aiming the building of an artificial cognitive system. First the general presentation of the artificial cognitive system, its objective, main principles and implementation phases are highlighted. The known patterns, which have a cultural (philosophical, psychological and linguistic) origin are then analyzed. Finally the details concerning the proposed pattern are pointed out. ©2010 IEEE.

Nonlinearity in the finite element simulations

Miklós Kuczmann

Publication Name: Przeglad Elektrotechniczny

Publication Date: 2010-12-20

Volume: 86

Issue: 12

Page Range: 83-86

Description:

The paper presents the four possible nonlinear schemes to solve nonlinear static magnetic field problems and eddy current field problems by the fixed point technique while using the polarization formulation to linearize the nonlinear curve of the constitutive law of ferromagnetic materials. The finite element method (FEM) has been chosen as a numerical tool to present the applicability of the technique.
