Publication Name: Proceedings of the European Conference on Innovation and Entrepreneurship, ECIE

Publication Date: 2015-01-01

Volume: 2015-January

Issue:

Page Range: 787-795

Description:

The authors will introduce Gyor as a significant member and centre both of this region and the Central European automotive industrial concentration. The study gives an overview of the emergence of the special Triple Helix Model in the analysed Hungarian town. Based on the results of the research programme 'Gyor Regional Vehicle Industrial District as a New Direction and Investment of Regional Development' (TÁMOP-4.2.2.A-11/1/KONV-2012-0010) completed in 2014, the authors will present the "Model of Gyor". The paper outlines the most significant theoretical and empirical results of the research which serves further development prospects, paths and examples to other Hungarian towns or to towns with similar industrial background around the world. The model represents the urban network structure as a 'living system' of Gyor that includes the university, the automotive industry and related innovative companies like Audi and the town (local government) as a coordinating factor.

'Lovers of Beauty': The oeuvres of george santayana, fred holland day and edward perry warren as exemplifications of aesthetics of existence influenced by the platonic eros

Nóra Horváth

Publication Name: Brno Studies in English

Publication Date: 2015-01-01

Volume: 41

Issue: 2

Page Range: 5-21

Description:

My theory is about the lovers of beauty who tried to aestheticize their existences in different ways, but with the same goal: To make life into an oeuvre. George Santayana created an aesthetic ontology, Fred Holland Day made a photo composition (Beauty is Truth), which is the essence of his aesthetics of existence, and Edward Perry Warren spiritualized the Male ideal shaped through the praising of the Uranian Eros. They used the Hellenic idea as a life-giving energy, they re-eroticised the philosophical thoughts about self-creation and the aesthetic way of life. The serious questions of private perfection and self-creation can be the basis of an ethics of personality. According to Agnes Heller it is always the ethics of one person. We have to illustrate it, if we want to speak about it. So, we have to examine one paradigmatic case to illustrate the essence of it.

Topological and energetic conditions for lithographic production of carbon nanotubes from graphene

Ibolya Zsoldos Istvan Laszlo David Fulep

Publication Name: Journal of Nanomaterials

Publication Date: 2015-01-01

Volume: 2015

Issue: Unknown

Page Range: Unknown

Description:

Density Functional Based Tight-Binding (DFTB) molecular dynamics (MD) simulations were performed for producing carbon nanotubes from graphene nanoribbons. The constant temperature simulations were controlled with the help of Nosé-Hoover thermostat. In our systematic study we obtained critical curvature energies and determined topological conditions for nanotube production from two parallel graphene nanoribbons. We obtained linear relationship between the curvature energy and the square of the curvature.

Enhancement and assessment of engineering soft skills in a game-based learning environment

No authors available

Publication Name: Proceedings of the European Conference on Games-based Learning

Publication Date: 2015-01-01

Volume: 2015-January

Issue:

Page Range: 178-185

Description:

Engineering education literature shares a consensual vision of the importance of soft skills for every workplace. Despite of the growing demand for graduates with high EQ (Emotional Intelligence Quotient), one of the main challenges of the industry is the lack of soft skills, in particular, communication and negotiation skills, problem-solving skills, interpersonal skills, as well as critical and creative thinking skills. This paper investigates the enhancement of skills in a game-based learning environment, which was specifically designed to develop both hard (technical) and soft (personal) skills of engineering students through hands on experiences and observations. The acquired data is gathered using data triangulation, and it consists of self-assessments, observations, questionnaires and technical measurements. Preliminary results indicate that the environment has a significant impact on soft skill development, and show a correlation between soft-skill development and the level of motivation and self-evaluation.

Parallel edge finite elementmethod to solve eddy current field problems

No authors available

Publication Name: Acta Technica CSAV (Ceskoslovensk Akademie Ved)

Publication Date: 2015-01-01

Volume: 60

Issue: 3

Page Range: 277-290

Description:

Two non-overlapping domain decomposition methods are presented and compared. They are used for parallelization of the finite element method with edge element approximation. In this case, the methods under investigation are the Schur complement method and the Lagrange multiplier based finite element tearing and interconnecting method, and their solvers. The performance of these methods and solvers is investigated in detail for two-dimensional eddy current field problems as case studies.

Multi-physics thermal analysis of permanent magnets motors with exterior rotor

No authors available

Publication Name: Civil-Comp Proceedings

Publication Date: 2015-01-01

Volume:

Issue:

Page Range: Unknown

Description:

This paper presents a magneto-thermal analysis of an external-rotor permanent magnet synchronous machine based on finite element method. The model developed can be used to predict the temperature distribution inside the motor during the rated operation. Electromagnetic computation is carried out with the aid of two twodimensional finite-element simulations of the cross-section of the permanent magnet motor [1]. In addition, the magnetic core losses of the stator and rotor are modelled based on the results from the electromagnetic analysis and a post-processing formula based on the loss-separation principle. To analyse the process of heat transfer in an electrical machine, empirical correlations are used to describe the convective heat transfer from the different surfaces of the permanent magnet motor. The heat transfer coefficients are determined using dimensionless numbers and the Nusselt number [2]. After the loss calculation, the temperatures of the machine are calculated using a three-dimensional finite element method. The results obtained from the model are compared with the experimental results from testing the prototype electric motor.

Numerical modeling of levees according to Eurocode 7

Edina Koch Ákos Wolf Róbert Szepesházi

Publication Name: Geotechnical Engineering for Infrastructure and Development Proceedings of the Xvi European Conference on Soil Mechanics and Geotechnical Engineering Ecsmge 2015

Publication Date: 2015-01-01

Volume: 4

Issue: Unknown

Page Range: 2019-2024

Description:

In many European countries, flood protection and development of levees has a great importance due to ever-increasing flood levels. The final version of Eurocode 7 includes three chapters that govern the levee design. They suggest mainly conventional concepts and principles but do not provide a comprehensive design methodology for use in practice as it was formerly given in the national standards. Analytical seepage calculations used in present-day practice are based on numerous simplifying assumptions, so they often do not simulate actual conditions. The method of slices, generally used for stability analysis, is sometimes criticized for theoretical reasons. Recently, development of numerical modeling and software have employed coupled finite element analysis for mechanical and hydraulic problems. A single FEM model can apply to levee design, stability analysis, underseepage and through seepage, and analysis of seepage forces. This paper reports research results gained about modeling levees by Plaxis to meet the requirements of the Eurocode 7.

Saturation optimization of selective waste collection vehicles based on real-Time info-communication system

István Lakatos Ádám Titrik Dávid Czeglédi

Publication Name: Proceedings of the ASME Design Engineering Technical Conference

Publication Date: 2015-01-01

Volume: 9

Issue: Unknown

Page Range: Unknown

Description:

New technology trends are spreading in selective waste collection, which apply real-Time based info-communication systems defining the saturation of the containers. Merely defining the routes to containers is not enough; saturation of the waste gathering vehicle should also be measured for optimization. In practice, the compression scale of homogenous recyclable waste types is different meaning that saturation optimization cannot be based on this value. This study aims to provide answers to the above-mentioned problem. In order to have an extended analysis the whole city traffic should be taken into account as waste collection traffic may be obstructed by traffic itself. The RPC (Route Planning Center) will apply optimal control for the entire traffic network, which is elaborated by a network analyst pre-calculating network state parameters. The extended approach is based on a determined complex road network modelling technique. Thus further research will be able to integrate the circumstances of the entire traffic network like the definition of traffic network dependent optimal trajectory in chapter 8.
