Number archetypes in system realization theory concerning the fine structure constant

Peter Varlaki László Nádai József Bokor

Publication Name: 12th International Conference on Intelligent Engineering Systems Proceedings Ines 2008

Publication Date: 2008-09-02

Volume: Unknown

Issue: Unknown

Page Range: 83-92

Description:

In this paper we analyze in detail the central role of number '137', the so-called Fine Structure Constant in the collaboration of Pauli and Jung. First, we present the fascination or the obsession of Pauli for the interpretation of number '137'. Second, we treat the spontaneous messages originating from unconscious concerning number '137' in the well-known dreams of Pauli. We restrict our investigations to the dreams containing the especially important formulae of Fine Structure Constant (4π3 + π2 + π), and also that containing the so-called background models of mathematical control systems. Third, we shortly mention four of the numerous synchronicities arising during the Pauli-Jung collaboration. © 2008 IEEE.

Numbers and system representations in perspective of the Pauli-Jung correspondence

Peter Varlaki László Nádai József Bokor

Publication Name: Sami 2008 6th International Symposium on Applied Machine Intelligence and Informatics Proceedings

Publication Date: 2008-08-25

Volume: Unknown

Issue: Unknown

Page Range: 11-18

Description:

The paper deals with the basic features of the so-called synchronistic stochastic (control) systems on the basis of the extended Kalmanian system and realization theory, using the synchronicity paradigm of Jung and Pauli. It is shown that the introduced additive geometric structure number (characterizing the representation structure of synchronistic stochastic systems) is theoretically equivalent to the fine structure constant (determining e.g. the fine structure of hydrogen spectra) redefined by the authors of this paper. Finally the redefined form of fine structure constant as additive structure number (mediator number or identificator number) and the amplified interpretation of structural patterns of some important objects of cultural history, as well as the hypothetically related natural and geometric structure numbers, are compared. © 2008 IEEE.

Logistic conception for real-time based info-communication system applied in selective waste gathering

I. Lakatos Ádám Titrik T. Péter

Publication Name: 2017 IEEE 14th International Scientific Conference on Informatics Informatics 2017 Proceedings

Publication Date: 2017-03-27

Volume: 2018-January

Issue: Unknown

Page Range: 203-209

Description:

Decreasing of available raw materials, fossil energy source and new approach made recycling necessary and inevitable. For recycling selective waste areas have been placed, where inhabitants can drop their waste for free. Waste containers have different saturation time, while gathering process is predefined, therefore independently whether it is needed or not they will be emptied. Further problem is that there is no optimization on the way to the container, which results in serious environmental load (noise and air pollution). This study deals with high level route optimization to minimize environmental load concerning noise and air pollution and by the application of real-time communication the appropriate containers are only going to be emptied.

Fuzzy logic in agricultural and environmental research

Attila Piros Károly Tatárvári

Publication Name: Agrokemia Es Talajtan

Publication Date: 2017-06-01

Volume: 66

Issue: 1

Page Range: 201-222

Description:

The papers presented support the summaries of McBratney and Odeh (1997) and Jetter and Kok (2014), who stated during the detailed evaluation of the present state of fuzzy modelling, that fuzzy systems and models may be the important research methods of the future. "Soft" computing methods are gaining ever more ground in the field of soil, agricultural and environmental sciences. The possibility of setting boundaries that are not defined as categories with precisely set, distinctive definitions, and of working with data that are not easily quantifiable and insecure presents a great advantage. Provided a satisfactory mathematical and interdisciplinary research background is available, this is a comparatively simple, fast and cost-effective method, which is more exact than conventional ones, and which supplies results that can also be understood by laymen.

IS THE ENGINEERING STUDENTS' SELF-ASSESSMENT ACCURATE? ANALYSING MIDTERM TESTS IN TERMS OF SELF-ASSESSMENT ACCURACY

Nárcisz Kulcsár

Publication Name: Sefi 2022 50th Annual Conference of the European Society for Engineering Education Proceedings

Publication Date: 2022-01-01

Volume: Unknown

Issue: Unknown

Page Range: 2028-2033

Description:

There is a high drop-out rate in engineering higher education, the reasons can be grouped into four categories: economic explanations, individual pedagogical-psychological, learning-related reasons, socio-cultural influences. This paper discusses the problem of the accuracy of self-assessment among the individual pedagogical and psychological reasons. During the maths midterm tests, students self-assessed on each task, which was compared with the points given by the teacher. More than 80% of students overestimated their actual performance in all midterms, and this overestimation was moderate. Based on the relationship between accuracy scores and test results, students who achieved better results in the midterms gave more accurate self-assessments than those who performed poorly, which confirms the Dunning-Kruger effect in engineering education. Feedback based on their performance may affect the accuracy of self-assessment. Feedback from the midterm caused a significant improvement in self-assessment for students who met mid-term requirements, while there was no such improvement for those who did not. Thus, underperforming students did not benefit enough from the feedback from the first midterm, and the accuracy of their self-assessment did not improve. The fact that there is a significant difference in the accuracy of self-assessment between students who fulfilled mid-term requirements and those who did not. The self-assessments of the former was closer to the teacher's evaluation than those of the latter. This may be problematic because weaker students are less aware of their deficiencies due to their inaccurate self-assessment, and thus they may stop their preparation short of what is necessary, and may not ask for help when needed.

Theoretical Investigation of the Effect of Changes in Some Geometrical Parameters from the Point of View of the Energetic Behavior of the Roller Gearing Gearbox

József Polák

Publication Name: Chemical Engineering Transactions

Publication Date: 2023-01-01

Volume: 107

Issue: Unknown

Page Range: 379-384

Description:

In the article, the energetic analysis of the propulsion unit is presented by examining the geometrical parameters determining the friction phenomena at the ball-track connection. The novelty of the topic stems from the fact that the propulsion unit under investigation is a Hungarian invention, the energy analysis of which has not yet been dealt with in any form. To carry out the investigation, a mathematical model had to be created, which was built on the basis of analytical principles. With the help of the model, the energetic behavior of the propulsion unit can be analyzed at a theoretical level. To construct the mathematical model, the principles, research results, and models used in the case of ball bearings and ball screw drives were used, transformed, and applied in a suitable way. After the parameter tests, the analysis extended to the entire gear model, so the losses outside the ball-track connection, e.g., bearing friction, seal friction, oil friction, air friction, etc. losses, were also implemented in the mathematical model. By exploring the full efficiency field of the gearbox, it is possible to build a mathematical model that can be used to implement the propulsion unit model in an energy optimization algorithm for a given vehicle, engine-propulsion unit-vehicle combination.
