An improved index of interactivity for fuzzy numbers

József Mezei Peter Varlaki Robert Fuller

Publication Name: Fuzzy Sets and Systems

Publication Date: 2011-02-16

Volume: 165

Issue: 1

Page Range: 50-60

Description:

In this paper we will introduce a new index of interactivity between marginal possibility distributions A and B of a joint possibility distribution C. The starting point of our approach is to equip each γ-level set of C with a uniform probability distribution, then the probabilistic correlation coefficient between its marginal probability distributions is interpreted as an index of interactivity between the γ-level sets of A and B. Then we define the index of interactivity between A and B as the weighted average of these indexes over the set of all membership grades. This new index of interactivity is meaningful for the whole family of joint possibility distributions. © 2010 Elsevier B.V. All rights reserved.

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.

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.

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.

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.

Solution of the TEAM workshop problem No. 7 by the finite element method

Miklós Kuczmann Gergely Kovács

Publication Name: Przeglad Elektrotechniczny

Publication Date: 2011-01-01

Volume: 87

Issue: 3

Page Range: 99-102

Description:

This paper presents some potential formulations which can be derived from the "quasi-static" Maxwell's equations. The simulation results of the potential formulations are compared with each others focusing their CPU times and their accuracy - and with the measurement results, as well. The model -which was simulated - the TEAM workshop problem No. 7. The magnetic flux density and the eddy current were shown by the results of the simulation.

Meshfree vectorial interpolation based on the generalized stokes problem

Csaba Gáspár

Publication Name: Lecture Notes in Computational Science and Engineering

Publication Date: 2011-01-01

Volume: 79 LNCSE

Issue: Unknown

Page Range: 65-80

Description:

A vectorial interpolation problem is considered. In addition to the interpolation conditions taken at discrete points, a global, divergence-free condition is also prescribed. Utilizing the idea of the multi-elliptic interpolation, the divergencefree interpolation problem is converted to a generalized Stokes problem. To numerically solve this new problem, an Uzawa-type method and the method of fundamental solutions are proposed. In the second method, a linear system with large and dense matrix is to be solved, while in the first method, this problem is avoided. © 2011 Springer-Verlag Berlin Heidelberg.
