The system enables real-time observation of both the pilot's actions and vehicle parameters. The vehicle's pilot drives according to a predetermined driving strategy, optimized for minimizing energy consumption during vehicle operation. The telemetry system aims to provide real-time information about the pilot's driving and deviations from the predetermined strategy, offering additional opportunities for correction during operation. Additionally, it facilitates real-time observation of all vehicle and sensor data on the vehicle's CAN network. The paper discusses the determination of the driving strategy and presents its graphical representation for the pilot. A detailed description of the telemetry system's operation through wireless connection is provided in the paper. In terms of implementation, the driving strategy was formulated using MATLAB through optimization, while graphical display, data collection, and telemetry system development were implemented in the LabVIEW environment. The functionality of the created energy-efficient driving support framework was examined under real driving conditions. The application of the telemetry system and proposed hybrid optimization approach helped to further reduce the energy consumption by 8.54%.

The exploration of these n-best networks has proven pivotal for making informed decisions. Nevertheless, existing studies in this domain have not attempted to study the favourability of these generated networks based on their respective dynamic control performance. This performance metric reflects the network's ability to maintain target temperature even under disturbances. The network topologies play important role in both economic (i.e., total annual cost (TAC)) and dynamic control aspects. To address this gap, this work introduces a hybrid approach. First, all combinatorically feasible heat recovery networks are generated using P-HENS. Thereafter, each network undergoes dynamic control performance evaluation through Aspen Plus simulations. The final step involves optimization of the network structures based on fuzzy method which avoids over-prioritization. To illustrate the efficacy of the proposed methodology, it is applied to solve a 5-stream problem. Results showed that Network A with the least TAC ($122,249) is not necessarily associated with the greatest dynamic performance (with failure rate of 15 %). Network C which offers the balance performance (with TAC of $122,666 and failure rate of 0 %) is chosen. © 2024, AIDIC Servizi S.r.l.}, year = {2024}, eissn = {2283-9216}, pages = {73-78} } @article{MTMT:35535751, title = {Driving Strategy Optimization in Experimental Electric Vehicles: A Study on Optimization Algorithms}, url = {https://m2.mtmt.hu/api/publication/35535751}, author = {Pusztai, Zoltán and Szauter, Ferenc and Friedler, Ferenc}, doi = {10.3390/engproc2024079042}, journal-iso = {ENGENG PROC}, journal = {ENGINEERING PROCEEDINGS}, volume = {79}, unique-id = {35535751}, year = {2024}, eissn = {2673-4591} } @article{MTMT:34864486, title = {The P-graph application extension in multi-period P2P energy trading}, url = {https://m2.mtmt.hu/api/publication/34864486}, author = {Kong, Karen Gah Hie and Lee, Alvin Guo Jian and Teng, Sin Yong and Leong, Wei Dong and Orosz, Ákos and Friedler, Ferenc and Sunarso, Jaka and How, Bing Shen}, doi = {10.1016/j.rser.2024.114544}, journal-iso = {RENEW SUST ENERG REV}, journal = {RENEWABLE & SUSTAINABLE ENERGY REVIEWS}, volume = {200}, unique-id = {34864486}, issn = {1364-0321}, year = {2024}, eissn = {1879-0690}, orcid-numbers = {Teng, Sin Yong/0000-0002-2988-8053; Friedler, Ferenc/0000-0002-8069-8562; Sunarso, Jaka/0000-0002-5234-7431; How, Bing Shen/0000-0002-0969-9167} } @article{MTMT:34450618, title = {Electrification of oil refineries through multi-objective multi-period graph-theoretical planning: A crude distillation unit case study}, url = {https://m2.mtmt.hu/api/publication/34450618}, author = {Sahl, Abdulqader Bin and Orosz, Ákos and How, Bing Shen and Friedler, Ferenc and Teng, Sin Yong}, doi = {10.1016/j.jclepro.2023.140179}, journal-iso = {J CLEAN PROD}, journal = {JOURNAL OF CLEANER PRODUCTION}, volume = {434}, unique-id = {34450618}, issn = {0959-6526}, year = {2024}, eissn = {1879-1786}, orcid-numbers = {Sahl, Abdulqader Bin/0000-0002-9578-1107; How, Bing Shen/0000-0002-0969-9167; Friedler, Ferenc/0000-0002-8069-8562; Teng, Sin Yong/0000-0002-2988-8053} } @article{MTMT:34202437, title = {Technoeconomic Assessment of Recycling Routes for Chemicals: A Case Study of n-Hexane}, url = {https://m2.mtmt.hu/api/publication/34202437}, author = {Pimentel, Jean and Gerardo, Ruiz-Mercadob and Friedler, Ferenc}, doi = {10.3303/CET23103059}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {103}, unique-id = {34202437}, issn = {1974-9791}, abstract = {The circular economy has become one of the most popular topics in worldwide sustainability research. The imperious necessity of reducing resource consumption and decreasing waste generation has led to reincorporating materials at the end-of-life (EoL) stage into the productive chain. Nonetheless, the presence of hazardous substances in the EoL stage materials poses a significant challenge for the transition toward the production model. The adequate transformation of these materials into feedstocks requires their correct allocation into recovery plants and final destinations. Such an allocation can be decided by resorting to optimisation by generating the best alternative networks, from where the stakeholders may decide the most suitable recycling scheme. In this work, a graph-theoretic approach is introduced to identify the best alternatives to reincorporate industrial EoL chemicals into the productive chain. This contribution presents the initial approach to this problem, demonstrated through a case study considering the data reported on the public-access release inventory data for n-hexane. Different recycling routes are proposed for the case study by optimising the total treatment cost, and their advantages and disadvantages are discussed; moreover, their efficiency concerning the circular economy is measured by comparing the amount of recovered chemicals. By generating plausible recycling alternatives, this work contributes positively to analysing potential alternatives for circular economy and resource conservation in industry.}, year = {2023}, eissn = {2283-9216}, pages = {349-354}, orcid-numbers = {Pimentel, Jean/0000-0003-3359-4848} } @article{MTMT:34140047, title = {Retrofit heat exchanger network optimization via graph-theoretical approach: Pinch-bounded N-best solutions allows positional swapping}, url = {https://m2.mtmt.hu/api/publication/34140047}, author = {Teng, Sin Yong and Orosz, Ákos and How, Bing Shen and Jansen, Jeroen J. and Friedler, Ferenc}, doi = {10.1016/j.energy.2023.129029}, journal-iso = {ENERGY}, journal = {ENERGY}, volume = {283}, unique-id = {34140047}, issn = {0360-5442}, year = {2023}, eissn = {1873-6785}, orcid-numbers = {Teng, Sin Yong/0000-0002-2988-8053; Friedler, Ferenc/0000-0002-8069-8562} } @article{MTMT:34126562, title = {Energy Efficient Drive Management of Lightweight Urban Vehicle}, url = {https://m2.mtmt.hu/api/publication/34126562}, author = {Pusztai, Zoltán and Szauter, Ferenc and Friedler, Ferenc}, doi = {10.3303/CET23103043}, journal-iso = {CHEM ENG TR}, journal = {CHEMICAL ENGINEERING TRANSACTIONS}, volume = {103}, unique-id = {34126562}, issn = {1974-9791}, year = {2023}, eissn = {2283-9216}, pages = {253-258} } @article{MTMT:34064369, title = {Optimization of vertical farms energy efficiency via multiperiodic graph-theoretical approach}, url = {https://m2.mtmt.hu/api/publication/34064369}, author = {Pimentel, Jean and Balázs, László and Friedler, Ferenc}, doi = {10.1016/j.jclepro.2023.137938}, journal-iso = {J CLEAN PROD}, journal = {JOURNAL OF CLEANER PRODUCTION}, volume = {416}, unique-id = {34064369}, issn = {0959-6526}, year = {2023}, eissn = {1879-1786}, orcid-numbers = {Pimentel, Jean/0000-0003-3359-4848; Balázs, László/0000-0001-7319-9389; Friedler, Ferenc/0000-0002-8069-8562} }
