From individual memory to organizational memory (intelligence of organizations)

Andrea Bencsik I. Marosi V. Lore

Publication Name: World Academy of Science Engineering and Technology

Publication Date: 2009-08-01

Volume: 56

Issue: Unknown

Page Range: 1-6

Description:

Intensive changes of environment and strong market competition have raised management of information and knowledge to the strategic level of companies. In a knowledge based economy only those organizations are capable of living which have up-to-date, special knowledge and they are able to exploit and develop it. Companies have to know what knowledge they have by taking a survey of organizational knowledge and they have to fix actual and additional knowledge in organizational memory. The question is how to identify, acquire, fix and use knowledge effectively. The paper will show that over and above the tools of information technology supporting acquisition, storage and use of information and organizational learning as well as knowledge coming into being as a result of it, fixing and storage of knowledge in the memory of a company play an important role in the intelligence of organizations and competitiveness of a company.

AESTHETIC EXISTENCE AND THE THERAPY OF PASSIONS IN THE WORLD OF GEORGE SANTAYANA

Nóra Horváth

Publication Name: Pragmatism Today

Publication Date: 2023-12-01

Volume: 14

Issue: 2

Page Range: 22-39

Description:

The protagonist of my study, George Santayana, by idealizing love and sublimating sexual desires, has become the author of an aesthetics of existence elevated to literature and philosophy. He made self-cultivation and a life of satisfying desires a philosophical problem. His life's work is based on aesthetics, but it cannot be clearly placed within either Pragmatism or Platonism. My interpretation of Santayana from the perspective of the philosophy of desire takes the philosopher out of the conservative interpretative framework. His philosophy was centred on sensory perception, and although he sought spiritualism through his Platonism, his The Sense of Beauty is based on pleasure. His personal life and individual motivations are a vague background to his poetry and theoretical writings, and it is therefore necessary to view his creative world as a whole.

A COMPARATIVE STRUCTURAL ANALYSIS OF FOUR RADIOSONDE MODELS

János Jósvai Norbert Hegyi

Publication Name: Transactions on Aerospace Research

Publication Date: 2021-12-01

Volume: 2021

Issue: 4

Page Range: 68-81

Description:

In this study, we first performed a comprehensive structural analysis of four models of radiosondes (devices intended for use as the meteorological probe of a sounding balloon) manufactured by three different companies - Graw, Vaisala and Meteomodem. The radiosondes were disassembled for visual inspection and manual measurement, three-dimensional computed tomography images were taken of their inner structure, and the outer shapes of the radiosondes were scanned with a structured-light three-dimensional scanner. The structural properties of the radiosondes thus identified were then compared to one other, based on which the Meteomodem M10 was ranked as the least harmful in a potential collision. Next, the Meteomodem M10 radiosonde was used in collision tests with a heavy target and with a pumpkin model, in order to evaluate the possible damage caused by and to the radiosonde in different types of collisions.

Development of a sustainable optimization model for the rehabilitation of transport infrastructure

András Bakó László Gáspár

Publication Name: Acta Polytechnica Hungarica

Publication Date: 2018-01-01

Volume: 15

Issue: 1

Page Range: 11-33

Description:

About twenty years ago, the research activities aiming at the development of the optimal maintenance and rehabilitation strategies (models) of roads and bridges started in several countries, including Hungary. In the first foreign models, the deterioration depending on time and other parameters was given by Markov transition probability matrices. Due to the inaccuracies and inconsistencies of earlier models, a continuous model upgrading could have been carried out by many researchers world-wide. Besides, basically new models appeared in the literature, which are able to describe the actual processes more reliably. The research work of the authors of the paper has concentrated on Pavement Management Systems (PMSs) and Bridge Management Systems (BMSs). Since a common financing of roads and bridges is typical, a combined model of road pavement and bridge managements was developed by the authors increasing considerably the efficient use of available funds.

Procedure for Battery Module Assessment in Hybrid Vehicles

Szabolcs Kocsis Szurke

Publication Name: 2024 23rd International Symposium on Electrical Apparatus and Technologies Siela 2024 Proceedings

Publication Date: 2024-01-01

Volume: Unknown

Issue: Unknown

Page Range: Unknown

Description:

Electric and hybrid vehicles are becoming increasingly popular among environmentally conscious consumers, significantly impacting the automotive industry and the development of battery technologies. Fast diagnostic solutions are becoming critical as battery systems wear out over time and performance degrades. This study aims to investigate the battery system of a dedicated electric vehicle, the Toyota Prius, and its condition diagnostics. The test was performed by querying and saving the data using a custom Arduino-based specific measurement tool. The battery modules in the system were tested separately during the evaluation. During the condition assessment, the deviation from the average voltage of different sizes is analyzed and weighted individually depending on the size of the deviation. The analyses also cover more static and dynamic driving styles. The results show the influence of the driving style on the module voltage deviation. Furthermore, the method allows the detection and localization of weak battery modules in the system.

Testing Road Vehicle User Interfaces Concerning the Driver’s Cognitive Load

Péter Földesi Szabolcs Fischer Szabolcs Szalai Mykola Sysyn Gabor Kovacs Dmytro Kurhan Viktor Nagy

Publication Name: Infrastructures

Publication Date: 2023-03-01

Volume: 8

Issue: 3

Page Range: Unknown

Description:

This paper investigates the usability of touch screens used in mass production road vehicles. Our goal is to provide a detailed comparison of conventional physical buttons and capacitive touch screens taking the human factor into account. The pilot test focuses on a specific Non-driving Related Task (NDRT): the control of the on-board climate system using a touch screen panel versus rotating knobs and push buttons. Psychological parameters, functionality, usability and, the ergonomics of In-Vehicle Information Systems (IVIS) were evaluated using a specific questionnaire, a system usability scale (SUS), workload assessment (NASA-TLX), and a physiological sensor system. The measurements are based on a wearable eye-tracker that provides fixation points of the driver’s gaze in order to detect distraction. The closed road used for the naturalistic driving study was provided by the ZalaZONE Test Track, Zalaegerszeg, Hungary. Objective and subjective results of the pilot study indicate that the control of touch screen panels causes higher visual, manual, and cognitive distraction than the use of physical buttons. The statistical analysis demonstrated that conventional techniques need to be complemented in order to better represent human behavior differences.

On the topological characterization of 3-D polyhedral microstructures

Ágnes Csizmazia Imre Felde Tamás Réti

Publication Name: Materials Science Forum

Publication Date: 2007-01-01

Volume: 537-538

Issue: Unknown

Page Range: 563-570

Description:

To characterize topologically the polycrystalline microstructure of single-phase alloys computer simulations are performed on 3-dimensional cellular models. These infinite periodic cellular systems are constructed from a finite set of space filling convex polyhedra (grains). It is shown that the appropriately selected topological shape factors can be successfully used for the quantitative characterization of computer-simulated microstructures of various types.

Fast tomographic reconstruction on parallel hardware

Gabor Takacs G. Veres Zoltán Horváth

Publication Name: Aip Conference Proceedings

Publication Date: 2010-12-01

Volume: 1281

Issue: Unknown

Page Range: 1793-1796

Description:

Tomographic reconstruction is the mathematical procedure of approximating a function f, based on the integrals of f along a set of line sections. The need for fast tomographic reconstruction arises for example in the challenging problem of real time control of some plasma parameters in a fusion reactor. In this paper, we present a fast algorithm for tomographic reconstruction. A good property of our approach is that it fits well to hardware with two levels of parallelism (e.g. a GPU cluster). We also propose an objective evaluation method for measuring the quality of reconstruction on real datasets where f is unknown. We will demonstrate that our algorithm is able to perform more than 50 000 reconstructions per second at reasonably good quality, running on a relatively cheap hardware. © 2010 American Institute of Physics.
