In the culling decision process, the farmer has to take into account a number of factors, the complexity of which makes the decision-making task difficult. A crucial factor is the evolution of reproductive indicators. The aim of the research was to develop a microsimulation method that can be used to easily investigate the impact on profitability of increasing pregnancy rates and when the culling decision is made. In the microsimulation, the stock was examined without changing any other conditions. A microsimulation method has been developed to determine with high accuracy the effect of the pregnancy rate and the increase in culling days on the economic indicators of individual dairy farms. By microsimulation, the effect of changing these two parameters on the expected milk production of cows, the most important economic indicator for cattle farms, was investigated. The other parameters of economic importance were simulated using a cattle farm database. The purpose of microsimulation is to assist in producing certain managerial decisions in order to achieve better profitability and economic efficiency. In summary, the results showed that increasing the pregnancy rate can successfully reduce the length of the calving interval, but the improved pregnancy rate did not show a significant increase in milk production. In order to obtain results that can be used by farms, the authors intend to further develop the model in the future, adapting it to farms and taking into account their specificities.}, year = {2024}, eissn = {2076-2615}, orcid-numbers = {Tóth, Violetta/0000-0002-1394-716X; Mikó, Edit/0000-0001-6389-3502; Csendes, Tibor/0000-0002-1136-127X; Bánhelyi, Balázs/0000-0003-4408-9054} } @article{MTMT:34177876, title = {Testing the selection heuristic of the Accelerated Branch and Bound method}, url = {https://m2.mtmt.hu/api/publication/34177876}, author = {Heinc, Emília and Bánhelyi, Balázs}, journal-iso = {ANN MATH INFORM}, journal = {ANNALES MATHEMATICAE ET INFORMATICAE}, unique-id = {34177876}, issn = {1787-5021}, year = {2024}, eissn = {1787-6117}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054} } @article{MTMT:34177869, title = {Comparing structural constraints for accelerated branch and bound solver of process network synthesis problems}, url = {https://m2.mtmt.hu/api/publication/34177869}, author = {Heinc, Emília and Bánhelyi, Balázs}, doi = {10.14232/actacyb.297735}, journal-iso = {ACTA CYBERN-SZEGED}, journal = {ACTA CYBERNETICA}, unique-id = {34177869}, issn = {0324-721X}, year = {2024}, eissn = {2676-993X}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054} } @inproceedings{MTMT:34405554, title = {Metamaterials for Enhancing Reflection and Transmission}, url = {https://m2.mtmt.hu/api/publication/34405554}, author = {Vass, Dávid Imre and Szenes, András László and Bánhelyi, Balázs and Czirjákné Csete, Mária}, booktitle = {17th International Congress on Artificial Materials for Novel Wave Phenomena, Metamaterials 2023}, doi = {10.1109/Metamaterials58257.2023.10289339}, unique-id = {34405554}, year = {2023}, pages = {78-80}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054; Czirjákné Csete, Mária/0000-0002-3755-714X} } @inproceedings{MTMT:33723593, title = {Metamaterial properties of layered Babinet complementary patterns}, url = {https://m2.mtmt.hu/api/publication/33723593}, author = {Bánhelyi, Balázs and Tóth, Emese and Fekete, Olivér Antal and Czirjákné Csete, Mária}, booktitle = {17th International Congress on Artificial Materials for Novel Wave Phenomena, Metamaterials 2023}, doi = {10.1109/Metamaterials58257.2023.10289493}, unique-id = {33723593}, year = {2023}, pages = {81-83}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054; Czirjákné Csete, Mária/0000-0002-3755-714X} } @article{MTMT:33720276, title = {Metamaterial properties of Babinet complementary complex structures}, url = {https://m2.mtmt.hu/api/publication/33720276}, author = {Tóth, Emese and Bánhelyi, Balázs and Fekete, Olivér Antal and Czirjákné Csete, Mária}, doi = {10.1038/s41598-023-31685-7}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {33720276}, issn = {2045-2322}, abstract = {Single and multiple layers of sub-wavelength periodic Babinet complementary patterns composed of rounded nano-object miniarrays were investigated. In case of illumination with linearly and circularly polarized light the azimuthal orientation and handedness (in)dependence of (cross-polarized) copolarized transmitted signal components was proven for all types of patterns. Considerable (weak) asymmetric transmission was demonstrated in extended bands exclusively for both types of copolarized (cross-polarized) signals transmitted through single layer of convex miniarrays. Three-dimensional structures constructed with convex–concave–convex complex pattern-layers resulted in a negative index at the visible region boundary both for linearly and circularly polarized light illuminations. This is because dipolar modes on the convex nano-objects are synchronized with co-existent reversal dipoles on the concave nano-objects via interlayer coupling. Although during linearly polarized light illumination, the interlayer interaction decouples the localized and propagating modes excitable on the concave pattern in the 90° azimuthal orientation, the synchronization via tilted-rotating nanoring dipoles is almost perfect in the 0° azimuthal orientation. For circularly polarized light illumination, both the dispersion maps and the negative index phenomena synthesize the characteristics of the two orthogonal linearly polarized light illuminations. Important aspect is the appearance of a small/intermediate (large) time-averaged amplitude magnetic dipole due to the tilted (twisted) electric dipole on the concave nanoring, which less/more quickly turns (continuously rotates) with large/intermediate (small) out-of-plane tilting, when illumination is realized with linearly polarized light in the 90°/0° azimuthal orientation (with circularly polarized light). The location of the negative index can be predicted based on the copolarized transmittance signals computed for circularly polarized light illumination by using the linear base representation of Jones transmission matrix elements.}, year = {2023}, eissn = {2045-2322}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054; Czirjákné Csete, Mária/0000-0002-3755-714X} } @article{MTMT:33640115, title = {Plasmonic nanoresonator distributions for uniform energy deposition in active targets}, url = {https://m2.mtmt.hu/api/publication/33640115}, author = {Vass, Dávid Imre and Szenes, András László and Tóth, Emese and Bánhelyi, Balázs and Papp, István and Biró, Tamás Sándor and Csernai, László Pál and Kroó, Norbert and Czirjákné Csete, Mária}, doi = {10.1364/OME.471980}, journal-iso = {OPT MATER EXPRESS}, journal = {OPTICAL MATERIALS EXPRESS}, volume = {13}, unique-id = {33640115}, issn = {2159-3930}, year = {2023}, pages = {9-27}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054; Biró, Tamás Sándor/0000-0001-6188-8478; Czirjákné Csete, Mária/0000-0002-3755-714X} } @inproceedings{MTMT:33789583, title = {Individual plasmonic nanoresonators for lasing and spasing}, url = {https://m2.mtmt.hu/api/publication/33789583}, author = {Vass, Dávid Imre and Szenes, András László and Bánhelyi, Balázs and Czirjákné Csete, Mária}, booktitle = {Proceedings Frontiers in Optics + Laser Science 2022}, doi = {10.1364/FIO.2022.JW5A.55}, unique-id = {33789583}, abstract = {Plasmonic nanoresonators of different core-shell composition were optimized to maximize the stimulated emission in the near-field (NF-c-type), and to enter into the spasing operation region (NF-c * -type) by increasing the dye concentration in the gain medium.}, year = {2022}, orcid-numbers = {Bánhelyi, Balázs/0000-0003-4408-9054; Czirjákné Csete, Mária/0000-0002-3755-714X} } @inproceedings{MTMT:33789581, title = {Enhancement of lasing via complex plasmonic structures}, url = {https://m2.mtmt.hu/api/publication/33789581}, author = {Tóth, Emese and Fekete, O. and Bánhelyi, Balázs and Czirjákné Csete, Mária}, booktitle = {Proceedings Frontiers in Optics + Laser Science 2022}, doi = {10.1364/FIO.2022.JW4A.89}, unique-id = {33789581}, abstract = {Spectral engineering was realized by tailoring complex patterns of spherical plasmonic nanoresonators achievable via integrated lithography.
