With a focus on more conscious design and racing we developed a vehicle dynamics simulation program, which can be used to generate the dynamics functions of the cars from their technical characteristics and data. In this publication, we deal with the optimization of the technical parameters of the above-mentioned cars for various competition tasks using our simulation program. This is a completely new field of application of the used optimization methods. This concept and idea can effectively help student teams all over the world to prepare for various domestic and international competitions. One of the applied methods is a graphic procedure, the other one is the widely used “adaptive simulated annealing” (ASA). After a brief description of the simulation program, the applied optimization methods and developed MATLAB codes for them are described. Finally, to demonstrate the effectiveness of the methods, we optimize the parameters of a prototype race car for different competition tasks and present the obtained results.}, year = {2023}, eissn = {2076-3417}, orcid-numbers = {Szántó, Attila/0000-0001-9524-841X; Hajdu, Sándor/0000-0002-6959-4746; Szíki, Gusztáv Áron/0000-0001-6356-5373} } @article{MTMT:33132975, title = {Measurement System for the Experimental Study and Testing of Electric Motors at the Faculty of Engineering, University of Debrecen}, url = {https://m2.mtmt.hu/api/publication/33132975}, author = {Szíki, Gusztáv Áron and Szántó, Attila and Kiss, János and Juhász, György and Csernusné Ádámkó, Éva}, doi = {10.3390/app121910095}, journal-iso = {APPL SCI-BASEL}, journal = {APPLIED SCIENCES-BASEL}, volume = {12}, unique-id = {33132975}, abstract = {The Faculty of Engineering of the University of Debrecen has a long-standing tradition of developing electric and pneumatic-driven prototype race cars. These vehicles are regular participants in domestic and international university competitions. For more conscious development, thus, for more successful racing, a vehicle dynamics simulation program was developed by our research group. One of the main parts of the above program is the simulation of the drive system, including the electric motor. The input data for the motor simulation programs are the electromagnetic and dynamic characteristics of the motor. Most of these characteristics are usually not specified in the motor catalogue; thus, they have to be measured. In this paper, a detailed description of a recently developed measurement system (MS), which is capable of measuring all the above-mentioned characteristics, is presented. Additionally, by applying it, test measurements can also be performed on the motors to check the accuracy of the output functions generated by the simulation programs. Several experimental arrangements and procedures for specific experimental tasks are also presented here as examples for the application of the MS.}, year = {2022}, eissn = {2076-3417}, orcid-numbers = {Szíki, Gusztáv Áron/0000-0001-6356-5373; Szántó, Attila/0000-0001-9524-841X; Juhász, György/0009-0008-3906-2918; Csernusné Ádámkó, Éva/0000-0001-8638-9165} } @book{MTMT:30917266, title = {Mérnöki fizika}, url = {https://m2.mtmt.hu/api/publication/30917266}, isbn = {9789633188361}, author = {Szíki, Gusztáv Áron and Szántó, Attila}, publisher = {Debrecen University Press}, unique-id = {30917266}, year = {2019}, orcid-numbers = {Szíki, Gusztáv Áron/0000-0001-6356-5373; Szántó, Attila/0000-0001-9524-841X} } @article{MTMT:3184199, title = {Measurement of proton induced gamma-ray emission cross sections on Na from 1.0 to 4.1 MeV}, url = {https://m2.mtmt.hu/api/publication/3184199}, author = {Chiari, M and Alves, E and Bogdanović, Radović I and Cruz, J and Csedreki, László and Fonseca, M and Galaviz, D and Henriques, A and Jakšić, M and Jesus, AP and Kakuee, O and Kiss, Árpád Zoltán and Lagoyannis, A and Lourenço, F and Luís, H and Machado, J and Melon, B and Nuviadenu, CK and Salvestrini, L and Sharifzadeh, N and Siketić, Z and Szíki, Gusztáv Áron and Szikszai, Zita and Teubig, P and Velho, P and Zamboni, I and Zarza, M}, doi = {10.1016/j.nimb.2017.01.043}, journal-iso = {NUCL INSTRUM METH B}, journal = {NUCLEAR INSTRUMENTS & METHODS IN PHYSICS RESEARCH SECTION B-BEAM INTERACTIONS WITH MATERIALS AND ATOMS}, volume = {441}, unique-id = {3184199}, issn = {0168-583X}, abstract = {Abstract Differential cross sections for proton induced γ-ray emission from the reactions 23Na(p,p′γ)23Na (Eγ = 441 and 1636 keV) and 23Na(p,α′γ)20Ne (Eγ = 1634 keV) were measured for proton energies from 1.0 to 4.1 MeV in five different ion beam laboratories. Backscattered protons were collected simultaneously for normalization purposes, avoiding the measurement of the absolute values of the collected beam charge. The overall uncertainty was estimated to be around 7–8% for the cross section of the 441 keV γ-ray line from the 23Na(p,pγ1-0)23Na reaction, and of 8–12% for the cross section of the 1634–1636 keV γ-ray lines from the 23Na(p,αγ1-0)20Ne and 23Na(p,pγ2-1)23Na reactions. To check the possible anisotropy of the emitted 441 keV γ-ray, angular distribution measurements were performed at 1292, 1468, 1931, 2083 and 2851 keV proton energy, where sharp and well separated resonances occur in the excitation function; moreover, in the energy range from 2.5 to 4.1 MeV proton energy, differential cross sections at 0°, 45° and 90° were measured as well.}, keywords = {SODIUM; CROSS-SECTIONS; PROTON; Angular distribution; PIGE}, year = {2019}, eissn = {1872-9584}, pages = {108-118}, orcid-numbers = {Szíki, Gusztáv Áron/0000-0001-6356-5373} } @article{MTMT:3252547, title = {On computable classes of equidistant sets. equidistant functions}, url = {https://m2.mtmt.hu/api/publication/3252547}, author = {Vincze, Csaba and Vámosiné Varga, Adrienn and Oláh, Márk and Fórián, László}, doi = {10.18514/MMN.2018.2145}, journal-iso = {MISKOLC MATH NOTES}, journal = {MISKOLC MATHEMATICAL NOTES}, volume = {19}, unique-id = {3252547}, issn = {1787-2405}, year = {2018}, eissn = {1787-2413}, pages = {677-689}, orcid-numbers = {Vámosiné Varga, Adrienn/0000-0001-7914-2180} } @CONFERENCE{MTMT:26585302, title = {Zártcellás fémhabok belső szerkezetnek elemzése}, url = {https://m2.mtmt.hu/api/publication/26585302}, author = {Mankovits, Tamás and Varga, Tamás Antal and Kocsis, Imre Tibor and Manó, Sándor and Budai, István}, booktitle = {OGÉT 2017: XXV.
