As close as possible to the ungraspable - Somaesthetical and Deleuzian investigations on the Choreographical work of Pál Frenák

Nóra Horváth

Publication Name: Pragmatism Today

Publication Date: 2018-01-01

Volume: 9

Issue: 1

Page Range: 80-90

Description:

According to Shusterman with the notion of somaesthetics he wants to remind the contemporary readers that "philosophy could and should be practiced with one's body rather than being confined to "the life of the mind" (Shusterman 2012, 141.)" Consequently a philosophy can be expressible by one's body especially by a dancer's body or by a choreographer's work. I consider it to be a problem that a performance is not only the artwork of a creator but also the embodiment of the choreographer's philosophy. Not every dance choreographer has his own philosophy but those who have a characteristic "universe" and a peculiar style. I am going to reveal Pál Frenák's dance philosophy of somatic style while searching for that "existential weight" behind his works that is a crucial element in his artistic universe. How is it possible to approach a philosophy emotionally? Where is the limit between sense and sensibility in the reception of a dance performance? Instead of the analysis of concrete meanings of movements in one piece of art, dance philosophy should examine those processes that lead to a certain set of emotions and associations. I feel that conversation on contemporary dance would be a relevant topic in relation to somaesthetics. In my paper, I would like to attune somaesthetics and the Deleuzian sign theory to show the spiritual richness of the oeuvre of Pál Frenák.

Description:

Modeling traffic processes on large-scale road networks leads to the application of positive non-linear systems, Luenberger (1979). Running profiles can be gained from the applied large-size network model based on previous validations, which are sufficiently complex, complicated and built up by accelerations, decelerations and frequent stops. To develop accelerated methods for analyzing complex environmental impact on urban trajectories Our planned researches on emission encourage the further standardization and beyond that, the bilateral interoperability. According to our goals we point out on the differences, which have to be taken into account in the urban traffic also, and of which the lab measurements may vary. Real processes operate like this, which differ from those applied in laboratories and on roller brake test bench. In reality, however, vehicle emission strongly depends on driving style; moreover, it is also affected by any change in traffic flow. Significant differences can be realized in various regions and countries. The role of the optimal vehicle control is highlighted in every case. The same can be stated of the environmental loads of pollutant emissions and concerning the vehicle and environment dynamic. The detailed analysis introduced above has big impact on further automotive researches as being rapid and applicable for big number of vehicles providing statistical support.

Development opportunities for mobile and ICT learning in teacher education

Szilvia Petzné Tóth Bernadett Éva Pápai József Reider

Publication Name: Annales Mathematicae Et Informaticae

Publication Date: 2023-01-01

Volume: 59

Issue: Unknown

Page Range: 131-145

Description:

Learning is nowadays a continuous intellectual readiness to be able to cope with the current needs of the world of work. Students’ knowledge must be adapted accordingly and they must be capable of continuous development throughout their lives [8]. Changes in teaching-learning habits have already been observed at the beginning of the 21st century and those involved in education need to adapt to these changes with the appropriate transition to digital education what is more important today than ever be-fore. We asked our teacher-candidate students in an online questionnaire at the beginning and at the end of the “Teaching Methods in Mathematics” course. Our non-representative survey provided valuable data for course de-velopment. The aim of the survey was to find out students’ perceptions of the methods and tools they had learned in education. In the questionnaire at the beginning of the semester, we inquired our students about the types of work and methods they were familiar with, and then they gave their opinions about the different ICT tools, educational programmes and applications and how they were used. At the end of the semester, we interwieved them again whether they still held similar views on the subject or they had managed to change their views during the course.

Vibration levels in vans as a function of payload and leaf spring sheet number

Péter Böröcz

Publication Name: Journal of Testing and Evaluation

Publication Date: 2018-01-01

Volume: 46

Issue: 1

Page Range: Unknown

Description:

Measuring the vehicle vibration environment is essential to understanding and simulating the adequacy of a packaged-product system and its ability to ensure protection from transportation hazards. In the transportation industry, various vehicles are used to perform shipping tasks, including light commercial vehicles that became the most popular vehicles in single unit and lightweight package transportation. In this study, the transport vibration levels in vans were measured as a function of payload and number of leaf spring sheets used. The vans consisted of one with a 20 % payload of total capacity and another with an 80 % payload. The vans were divided into two groups: Those with a single leaf spring and those with a double leaf spring. The measurement conditions were the motorway and speed between 110 and 130 km/h. The results revealed that transport vibration levels are affected by payload and the number of spring sheets. A low payload and single leaf spring contributed to the highest transport vibration levels. The power density level peaks were between 1.5 and 3.5 Hz, then around 15 Hz.

Impact of temperature and pressure of supercritical CO2 media on the physicochemical properties and electrochemical performance of rGO-Sulfur cathodes for rechargeable Li-S batteries

Tamás Szabó Márton Szabados Dóra Zalka Márton Kőrösi Péter B. Nagy Anna Bulátkó Lakshmi Shiva Shankar Edit Székely Krisztina László Robert Kun

Publication Name: Journal of Power Sources

Description:

Supercritical carbon dioxide (scCO2) is a non-toxic, inert, and widely used solvent in green chemistry, offering tunable properties such as density, diffusivity, viscosity, and polarity, adjustable through temperature, pressure, or co-solvent addition. This study employs the Design of Experiment (DoE) methodology to optimize scCO2-assisted synthesis of Li-S battery cathodes, presenting the first systematic investigation of how scCO2 conditions affect the structural and surface properties of reduced graphene oxide (rGO) during sulfur decoration. Results show that temperature and pressure significantly influence sulfur integration and cathode performance. By combining DoE with detailed electrochemical impedance analysis using complex nonlinear least squares fitting, the study provides deeper insight into composite electrochemical behavior under varying conditions. An optimal rGO structure with low charge transfer resistance, enabling efficient ion and electron transport, was obtained at 150 bar and 60 °C, balancing sulfur loading and pore accessibility. Conversely, harsher conditions (180 bar, 80 °C) caused sulfur agglomeration and higher resistance, reducing performance. These findings highlight the necessity of precisely controlling scCO2 synthesis parameters to enhance cathode structure and improve electrochemical performance and long-term stability of Li-S batteries.

Sustainable corporate environmental information disclosure: Evidence for green recovery from polluting firms of China

Laszlo Vasa Qin Chen Fengjiao Long Jian Wang Lu Xu

Publication Name: Frontiers in Environmental Science

Publication Date: 2022-09-29

Volume: 10

Issue: Unknown

Page Range: Unknown

Description:

For a greener society, good corporate environmental information disclosure is crucial. This study empirically examines the influence of media attention and state-owned equity, and their interaction on corporate environmental information disclosure by A-share heavily polluting firms in the Shanghai and Shenzhen stock markets from 2015 to 2019. The results show that state-owned equity can improve the level of corporate environmental information disclosure; however, it mainly affects financial environmental information disclosure. Media attention also improves the level of corporate environmental information disclosure, but only for non-financial environmental information. Moreover, media attention and state-owned equity have a certain substitution effect on environmental information disclosure: a higher state-owned equity ratio weakens the positive effect of media attention on environmental information disclosure. To improve environmental information disclosure, the government must clarify disclosure standards to improve the comparability of environmental information. In addition, media and shareholders can fully leverage their external and internal supervisory roles to promote the environmental responsibilities of firms. Our findings can be useful for further promoting corporate environmental information disclosure and developing relevant policies.

Experimental Analysis of a Turbocharger: Influence of Oil Supply Temperature and Pressure on the Bifurcation Phenomenon in Subsynchronous Frequencies

Cs Tóth-Nagy Márk Pesthy Máté Boros

Publication Name: Lubricants

Publication Date: 2025-03-01

Volume: 13

Issue: 3

Page Range: Unknown

Description:

This study presents an experimental analysis of a turbocharger equipped with a semi-floating bearing system, with a particular focus on the bifurcation phenomenon within the subsynchronous vibration spectrum. A predefined design of experiments (DoE) methodology was employed to determine the measurement domains to be analyzed, where the primary input parameters included the lubricant supply temperature and pressure values. The bifurcation phenomenon in relation to the physical parameters of the system is observed via vibration and displacement sensors in two directions, enabling the collection of subsynchronous frequency data for further insights into the influence of lubricant parameters on the rotor system. While the nonlinear effect of oil temperature is well studied in the literature. However, the combined effect of oil supply temperature and pressure was not yet examined, which was the focus of the present study. This paper aims to investigate its coupled effects on the bifurcation phenomenon associated with both lubricant temperature and pressure. The occurrence of the introduced phenomenon is further examined to enhance the understanding of the uncharted behavior of turbocharger rotors and other rotor-bearing-based machinery.

Page Range: 323-335

Description:

After the Hungarian transition, the joining the EU and by the employment agreements among the European countries the west-wards migration brisked up. The high unemployment, the marketable professions and knowledge of languages helped the qualified experts to emigrate for better job and salary or prestige into the western European countries. Researching the Hungarian migrant potential it is verifiable; learnt material/occupancy and knowledge gained in Hungary almost lost as the employees that migrate, do not strive to get a job in accordance with their knowledge but in case they do so, it is without success. The brain waste tendency and underemployment is to be mentioned better, than the brain drain in case of the Hungarian high-skilled (BA, MA) employees obtaining a job abroad. This study is about to reveal the problems of mentioned above and this study is supported by the result of the survey made in the EU-15 among the Hungarian economics graduated migrants, examines the causes and in the focus there are the migrant motivations of the high-skilled young generation after the crisis. The survey's period is 2012-13 and it was carried out in a form of a questionnaire.
