Twin concept of fine structure constant as the 'self number-archetype' in perspective of the Pauli-Jung correspondence

Peter Varlaki Imre J. Rudas

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2009-12-01

Volume: 6

Issue: 2

Page Range: 77-108

Description:

The paper-similarly to our earlier publications since 1993 - is trying to 'synchronize' early quantum physics, the Kalmanian representation theory, Jungian analytic psychology, and certain aesthetical categories. The number '137', the so-called inverse Fine Structure Constant (IFSC), is placed at the centre of this heuristic and epistemological experiment, along with the scientific cooperation of Pauli and Jung. A new possibilistic twin concept of "controlling-observing equations" is proposed for the reinterpretation of the FSC and other Number Archetypes on the basis of the Hermeneutic and symbolic languages found in the W. Pauli and C. G. Jung " Correspondence". The first part of the paper deals in first line with the introduction of the possibilistic twin concept of FSC together with its interpretation according to the hermeneutical "tradition" of the Pauli-Jung collaboration.

Nonlinear two-dimensional motional finite element modeling of a Rotational eddy current field problem

Miklós Kuczmann Daniel Marcsa

Publication Name: Przeglad Elektrotechniczny

Publication Date: 2009-12-01

Volume: 85

Issue: 12

Page Range: 110-113

Description:

Rotational eddy current field problems with nonlinear effect can be solved by different potential formulations combining motion voltage term. The potential formulations are the motional Az.ast; - A - potential formulation and the motional T,φ - φ - potential formulation taking the nonlinearity of the material into account. The nonlinearity has been handled by the fixed point iteration technique (FPT). The paper presents and compares these formulations through the modified version of TEAM Problem No. 30a, which contains two induction motors.

Comprehensive investigation of the corrosion state of the heat exchanger tubes of steam generators

No authors available

Publication Name: European Corrosion Congress 2009, EUROCORR 2009

Publication Date: 2009-12-01

Volume: 2

Issue:

Page Range: 1212-1220

Description:

Evaluating the water chemistry in the primary circuit and the effect of chemical decontamination of the heat exchanger tubes performed by the AP-CITROX procedure at Paks NPP (Hungary), a project dealing with the comprehensive investigation of the general corrosion state of the steam generators (SGs) has been initiated. Owing to the fact that there is no investigation method available for the in-situ monitoring of the inner surfaces of heat exchanger tubes, a research program based on sampling as well as on ex-situ electrochemical and surface analytical measurements were developed and elaborated. In the time period of 2000-2008 - within the frame of the above project - 45 stainless steel specimens, cut out from various locations of the steam generators of the Paks NPP were investigated. Besides to the corrosion characteristics (corrosion rate, thickness and chemical composition of the protective oxide-layer) surface properties (morphology, chemical and phase compositions) of the passive layer formed on the inner surface of above heat exchanger tubes were studied, too. The passivity of the inside surface of the stainless steel specimens was measured by voltammetry, the morphology, chemical and phase compositions of the oxide layer formed on the surface were analyzed by SEM-EDX, XRD and CEMS methods. The great number of experimental results allowed us to develop an electronic database which involves the results of the above corrosion experiments, and also some special characteristics of the tubes (e.g. location in the SGs, surface pretreatment by decontamination, if any, etc). Evaluating the main relations among these parameters may contribute to the identification of important processes affecting the corrosion state of steam generators, and highly decisive concerning a life time prolongation project of VVER-type nuclear reactors. In the present work we provide a brief overview on these experiments, some characteristic results, the database developed, as well as some novel findings.

The application of fuzzy logic for the solving of conflicts in the dispositional tasks of a railway traffic control center

Tibor Héray Gabor Rozsa István Tömpe László T. Kóczy

Publication Name: IEEE AFRICON Conference

Publication Date: 2009-12-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

The paper considers a railway timetable related problem in a simplified form, generated by the delay of one or several incoming trains at a given station. Usually there are connecting trains in the timetable, especially in up to date periodic timetables and thus incoming delays might indicate the necessity of introducing a delay with connecting outgoing trains. A hierarchical fuzzy rule base is applied in order to determine the optimal outgoing delay, taking also usual restrictions into consideration. Three examples are shown. © 2009 IEEE.

Page Range: 1508-1513

Description:

In our previous work we proposed a Multilayer Perceptron Neural Networks (MLP NN) consisting of fuzzy flipflops (F3) based on various operations. We showed that such kind of fuzzy-neural network had good learning properties. In this paper we propose an evolutionary approach for optimizing fuzzy flip-flop networks (FNN). Various popular fuzzy operation and three different fuzzy flip-flop types will be compared from the point of view of the respective fuzzy-neural networks' approximation capability.

Comparison of railway track transition curves

Szabolcs Fischer

Publication Name: Pollack Periodica

Publication Date: 2009-12-01

Volume: 4

Issue: 3

Page Range: 99-110

Description:

There are no design parameters related to speeds exceeding 160 km/h in the effective Hungarian railway design rules. In the relevant international standard (ENV 13803) a similar speed limit is 300 km/h. This paper deals with the comparative of these regulations. Parameters of two transition curves used in Hungary and other used in Austria are determined. The importance of the new design parameters provided by ENV 13803 is assessed. It is demonstrated that the usability of the clothoide transition curves is unnecessarily restricted for the speeds v≤120 km/h in the Hungarian regulations. © 2009 Akadémiai Kiadó.

Crisis, value, survival - Cross-reply to Kálmán Kulcsárs introduction: "modernization, regime change and the hungarian reality"

Károly Varga

Publication Name: Tarsadalomkutatas

Publication Date: 2009-12-01

Volume: 27

Issue: 4

Page Range: 401-422

Description:

The Editor-in-Chief of Társadalomkutatás starts the debate from one of the main topics of his research oeuvre, from modernisation as a 'dress rehearsal' of the scale of pilot study for the Delphi volume of discussions under preparation and to be edited by Kálmán Kulcsár and the present author. The first response to the paper is the present one, reversing the perspective of Professor Kulcsár's paper which is progressing in the history of concepts, and the author starts from the fact of the present global crisis and goes back in quest of elements that contain crisis potential right from the outset and can be grasped in the set of values of modernisation. Listing the relevant theses of several authors he presents evidence that besides the undoubtedly evolutionary achievements of modernisation some problematic factors as parasitic side-effects have been maturing in the value control of the process. Based on Hellemans he presents that in the face of the initial resistance of the institution of traditionally conservative values (such as the Roman Catholic Church) some basic values of modernisation would continue to show the direction, while he stresses of the discussion of modernisation between Daniel Bell and Habermas of the '70s that the forecast of disintegration implied in "consume hedonism" condemned by Bell proved to be more realistic than the perspective of the "project of modernisation" defended by Habermas. The current statements of the two authors already support this. In harmony with Bell's line Hofstede makes the fundamentally short-term orientation of the American set of values for the global crisis, contrasting it to the Chinese par excellence long-term one. Wallerstein's theory of centre and periphery also originates the present crisis from old contradictions, among others from the schizophrenic situation of the periphery which can only expect to enjoy the advantages of getting organically included in world economy only at the cost of the rapid amortisation of its human capital. The human capital model of Schulz may be linked to this, while it directs attention to the trend threatening survival in Hungary in view of domestic male mortality. It is at this point that my paper joins the conclusions of Professor Kulcsár's opening paper namely that the modernisation of the globalised world liveable by us as well is the adaptation of the society by its own conditions, together with the continuous improvement of those conditions. Thus following the warning of Domokos Kosáry we may avoid the present variant of dual mistake committed in the 20th century: namely disregarding the current space of mobility in global politics, and self-exposure to the 'favours' of great powers as well as of multinationals. © 2009, Akadémiai Kiadó.

Improving pavement performance by compact-asphalt technology

Peter Fuleki

Publication Name: Pollack Periodica

Publication Date: 2009-12-01

Volume: 4

Issue: 3

Page Range: 111-120

Description:

A quite considerable part of the Hungarian road infrastructure is in critical condition due to the steady traffic growth of heavy good vehicles and increasing frequency of extreme weather conditions. The author analyzed the most typical deterioration problems of asphalt pavements, their possible causes and the reasons of shortened service life of these pavements. The impacts of construction compact-asphalt technology' modifications on the asphalt pavements were studied. Based on laboratory analysis of appropriate specimens, as a result of these technology modifications, changing characteristics of the asphalt pavement were revealed and more reliable data were provided for lifecycle costing and maintenance parameters used as input in the economic analysis. © 2009 Akadémiai Kiadó.

Publication Name: Studies in Computational Intelligence

Publication Date: 2009-12-01

Volume: 243

Issue: Unknown

Page Range: 447-456

Description:

Several optimalization algorithms have been proposed for the solution of the basic network flow algorithms, such as the minimal and the multiterminal minimal path of a network having cost (distance) function, maximal flow of a capacitated network. In this paper we present these algorithms in a special network in which on the edges a gain function is given. On the edge (x,y) of the network a t(x,y) transportation cost is defined. In the course of the transportation on the edge (x,y) the goods loose a part of there weight. If one unit of goods is transported from point x to point y then k(x,y) unite of goods arrive at point y, where 0
