Güneş Bağlantılı Pasif Stratejilerin Erken Tasarım Sürecine Entegre Edilmesi: Kümülatif Bir İş Akışı Önerisi
No full textGünümüzde, küresel enerji ve iklim krizinin etkileri, mimari uygulamalarda enerji verimliliğinin önemini giderek daha fazla vurgulamaktadır. Mevcut yapıların enerji verimliliğini sağlamak, yapının mevcut durumundan kaynaklanan sınırlamalar nedeniyle önemli zorluklar barındırmaktadır. Bu nedenle, enerji verimliliği ile ilgili kararların erken tasarım aşamalarında alınması daha avantajlıdır. Ancak, bu erken tasarım aşaması, çok sayıda alternatifin bulunması, çeşitli olası senaryoların mevcudiyeti ve sınırlı veri nedeniyle doğası gereği karmaşıktır. Bu aşamada, mimarların kullanımına sunulan iklimsel verilerin artırılması, bu parametrelerle uyumlu tasarım önerilerinin geliştirilmesine katkı sağlayarak tasarım sürecinin etkinliğini artırmaktadır. Bu tez, bu doğrultuda iklimsel verilerin erken tasarım sürecine entegre edilmesini amaçlamaktadır. Güneşle ilgili enerji verimli tasarım, enerji verimliliği bağlamında önemli bir husus olarak öne çıkmaktadır. Tasarımın erken aşamalarında güneşin etkilerinin anlaşılması, kütle formu, plan düzeni, yapı kabuğu ve malzeme seçimi gibi çeşitli tasarım kararlarını büyük ölçüde etkilemektedir. Ancak, bu enerji verimli tasarım viii yöntemlerinin uygulanması da belirli zorluklar getirmektedir. Bu nedenle, enerji verimli tasarımda analiz yöntemlerini ve tasarım stratejilerini kullanmada belirli bir sıra ve sınıflandırmanın oluşturulması kritik öneme sahiptir. Bu çalışma, enerji verimli stratejilerin erken tasarım sürecine, önceki stratejilerin etkinliğini olumsuz etkilemeden tutarlı bir sırayla entegre edilmesini hedeflemektedir. Bu bağlamda, kütle çalışmaları ile başlayıp daha ayrıntılı tasarım kararlarına doğru ilerleyen kümülatif bir süreç planı ve iş akışı önerilmektedir. Bu iş akışı, mimari tasarım sürecini aşamalara ayıran ve her aşamanın başında sunulan strateji önerileriyle tasarıma katkı sağlamayı amaçlayan bir uyarı-öneri algoritması olarak işlev görmektedir. Bu iş akışının entegrasyonunu ve avantajlarını gözlemlemek amacıyla, güneş maruziyeti açısından zorlu koşullara sahip İzmir şehrinde bir vaka çalışması gerçekleştirilmiştir. Vaka çalışmasının sonuçları, bu iş akışının mimari proje süreçlerini yavaşlatmadan öneriler sunma potansiyeline sahip olduğunu göstermektedir. İş akışı, tasarıma 17 farklı stratejinin entegrasyonunu değerlendirmiş ve bazı stratejilerin birbiriyle uyumlu olduğunu, bazılarının ise alternatif olarak çalıştığını ortaya koymuştur. Farklı aşamalardaki projelere uygulanabilirlik, bazı öneriler kullanılmasa bile iş akışının devam edebilmesi gerçeğiyle gösterilmiştir. Enerji verimli tasarımda, tutarlı bir sıra ve eleme yöntemiyle mümkün kılınan kümülatif bir yaklaşım, bu çalışmada önerilen iş akışıyla elde edilebilir.In contemporary times, the effects of the global energy and climate crisis have increasingly underscored the importance of energy efficiency in architectural practices. Achieving energy efficiency in existing structures presents significant challenges, as the interventions that can be made are limited due to the building's pre-existing state. Consequently, making decisions regarding energy efficiency during the early design stages is more advantageous. However, this early design phase is inherently complex due to the abundance of alternatives, the variety of potential scenarios, and the limited data available. At this stage, increasing the climatic data available to architects contributes to the development of design proposals that align with these parameters, thereby enhancing the effectiveness of the design process. This thesis, therefore, aims to integrate climatic data into the early design process. Solar-related energy-efficient design emerges as a significant consideration within the context of energy efficiency. Understanding the effects of the sun during the early stages of design greatly influences various design decisions, such as massing, plan layout, building envelope, and material selection. However, the implementation of these energy-efficient design methods also brings certain challenges. Therefore, it is vi crucial to establish a specific sequence and classification to use analysis methods and design strategies in energy-efficient design. This study seeks to integrate energy-efficient strategies into the early design process in a consistent order that does not negatively affect the effectiveness of previous strategies. In this context, a cumulative process plan and workflow are proposed, beginning with massing studies and progressing towards more detailed design decisions. This workflow functions as a warning-suggestion algorithm, which divides the architectural design process into stages and aims to contribute to the design through strategy suggestions presented at the beginning of each stage. To observe the integration and advantages of this workflow, a case study was conducted in the city of İzmir, which poses challenging conditions in terms of solar exposure. The results of the case study indicate that this workflow has the potential to provide recommendations without slowing down the architectural project processes. The workflow evaluated the integration of 17 different strategies into the design, revealing that some strategies are compatible with each other, while others serve as alternatives. Applicability to projects at different stages is demonstrated by the fact that the workflow can continue even if certain recommendations are not used. In energy-efficient design, a cumulative approach made possible through a consistent sequence and elimination method is achievable with the workflow proposed in this study

Exergetic and Exergoeconomic Assessments of a Diesel Engine Operating on Dual-Fuel Mode With Biogas and Diesel Fuel Containing Boron Nitride Nanoparticles
No full textThis study investigates the exergetic and exergoeconomic analyses of a diesel engine operated on dual-fuel mode with fuelled both diesel fuel–boron nitride nanofuel and biogas purchased commercially. The experiments were performed for diesel fuel, diesel + 100 ppm boron nitride nanoparticle, diesel + 100 ppm boron nitride nanoparticle + 0.5 L min−1 biogas, diesel + 100 ppm boron nitride nanoparticle + 1.0 L min−1 biogas and diesel + 100 ppm boron nitride nanoparticle + 2.0 L min−1 biogas at various engine loads (2.5 Nm, 5.0 Nm, 7.5 Nm, and 10.0 Nm) and fixed crankshaft speed of 1500 rpm. The obtained experimental data were used to realize exergetic and exergoeconomic analyses. Among the fuels considered in this study, diesel + 100 ppm boron nitride nanoparticle nanofuel had the best exergetic and exergoeconomic results. As a result, at engine load of 10 Nm, the exergy efficiency of test engine and specific exergy cost of crankshaft work were obtained to be 29.12% and 124.86 US GJ−1 for diesel fuel, 25.50% and 141.92 US GJ−1 for diesel + 100 ppm boron nitride nanoparticle + 1.0 L min−1 biogas, and 21.09% and 171.92 US$ GJ−1 for diesel + 100 ppm boron nitride nanoparticle + 2.0 L min−1 biogas, respectively. It is clear that biogas addition to combustion made worse the exergetic and exergoeconomic performances of test engine. As a conclusion, it can be said that diesel + 100 ppm boron nitride nanoparticle nanofuel can be used as alternative fuel to D100 in terms of exergy and exergoeconomics. © Akadémiai Kiadó, Budapest, Hungary 2023

Crushing Performance of an Additively Manufactured Bio-Inspired Hybrid Energy Absorption Profile
No full textBio-inspired structures have applications in various industries, including automotive, defense, aerospace, and biomedical industries, owing to their combination of high-strength and lightweight properties. To enhance their energy absorption performance, a novel design was developed by integrating a spiral component, inspired by the cross section of the date palm tree trunk (Latin: Phoenix dactylifera), into an empty aluminum tube. The energy absorption performance of a bio-inspired hybrid energy-absorbing profile (BIHEAP) was experimentally and numerically investigated. To ensure the reliability of the numerical studies, finite element models were generated using ANSYS LS-DYNA and subsequently validated through axial crushing tests. Design optimization studies were carried out using surrogate-based models, such as the response surface model and Kriging surrogate models, to increase the energy absorption performance of the BIHEAP, which has three different design variables (spiral revolution, wall thickness, and number of spiral tubes). The initial design of the BIHEAP exhibited a specific energy absorption capacity (SEA) and crush force efficiency (CFE) that surpassed those of the empty aluminum tube by 17.2 % and 4.6 %, respectively. The optimized BIHEAP design demonstrated SEA and CFE values that were 21.4 % and 32 % greater than those of the empty aluminum tube, respectively. When the initial and optimized BIHEAP design were compared, it was found that SEA and CFE was increased by 3.5 % and 26.1 %, respectively.Scientific and Technological Research Council of Turkey (TUEBIdot;TAK) [222M364]; TOBB University of Economics and Technology; Graduate School of Engineering and ScienceThe authors acknowledge the The Scientific and Technological Research Council of Turkey (TUEB ; Idot;TAK) award number 222M364 and TOBB University of Economics and Technology, Graduate School of Engineering and Science for providing funding and scholarship for the first author

Search for the Zγ Decay Mode of New High-Mass Resonances in Pp Collisions at S=13 Tev With the Atlas Detector
No full textThis letter presents a search for narrow, high-mass resonances in the Zγ final state with the Z boson decaying into a pair of electrons or muons. The s=13 TeV pp collision data were recorded by the ATLAS detector at the CERN Large Hadron Collider and have an integrated luminosity of 140 fb−1. The data are found to be in agreement with the Standard Model background expectation. Upper limits are set on the resonance production cross section times the decay branching ratio into Zγ. For spin-0 resonances produced via gluon–gluon fusion, the observed limits at 95% confidence level vary between 65.5 fb and 0.6 fb, while for spin-2 resonances produced via gluon–gluon fusion (or quark–antiquark initial states) limits vary between 77.4 (76.1) fb and 0.6 (0.5) fb, for the mass range from 220 GeV to 3400 GeV. © 2023 The Author(s)IN2P3-CNRS; CC-IN2P3; 2014-2021; SCI/013; U.S. Department of Energy, USDOE; Alexander von Humboldt-Stiftung, AvH; Alabama Space Grant Consortium, ASGC; Brookhaven National Laboratory, BNL; Karlsruhe Institute of Technology, KIT; H2020 Marie Skłodowska-Curie Actions, MSCA; Multiple Sclerosis Scientific Research Foundation, MSSRF; CERN; Göran Gustafssons Stiftelser; Natural Sciences and Engineering Research Council of Canada, NSERC; National Research Council Canada, NRC; Canada Foundation for Innovation, CFI; Science and Technology Facilities Council, STFC; Leverhulme Trust; European Research Council, ERC; European Cooperation in Science and Technology, COST; Australian Research Council, ARC; National Stroke Foundation, NSF; Neurosurgical Research Foundation, NRF; Helmholtz-Gemeinschaft, HGF; Minerva Foundation; Deutsche Forschungsgemeinschaft, DFG; Agence Nationale de la Recherche, ANR; Japan Society for the Promotion of Science, JSPS; Ministry of Education, Culture, Sports, Science and Technology, MEXT; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF; Danmarks Grundforskningsfond, DNRF; Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP; National Natural Science Foundation of China, NSFC; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT; Fundação para a Ciência e a Tecnologia, FCT; Bundesministerium für Bildung und Forschung, BMBF; Chinese Academy of Sciences, CAS; Austrian Science Fund, FWF; Generalitat de Catalunya; Ministry of Science and Technology of the People's Republic of China, MOST; Agencia Nacional de Promoción Científica y Tecnológica, ANPCyT; Nederlandse Organisatie voor Wetenschappelijk Onderzoek, NWO; Bundesministerium für Wissenschaft, Forschung und Wirtschaft, BMWFW; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq; Nella and Leon Benoziyo Center for Neurological Diseases, Weizmann Institute of Science; Israel Science Foundation, ISF; Instituto Nazionale di Fisica Nucleare, INFN; Narodowe Centrum Nauki, NCN; Javna Agencija za Raziskovalno Dejavnost RS, ARRS; Ministarstvo Prosvete, Nauke i Tehnološkog Razvoja, MPNTR; Ministerio de Ciencia e Innovación, MICINN; Centre National pour la Recherche Scientifique et Technique, CNRST; Staatssekretariat für Bildung, Forschung und Innovation, SBFI; British Columbia Knowledge Development Fund, BCKDF: 21/SCI/017; European Regional Development Fund, ERDF; Defence Science Institute, DSI; Narodowa Agencja Wymiany Akademickiej, NAWA; Institutul de Fizică Atomică, IFA; Agencia Nacional de Investigación y Desarrollo, ANID; Royal Society of South Australia, RSSA; Irish Rugby Football Union, IRF
Exergetic and Exergoeconomic Assessments of a Diesel Engine Fuelled With Waste Chicken Fat Biodiesel-Diesel Blends
No full textResearchers have constantly been looking for renewable alternative fuels due to high fuel price volatility, energy security concerns, and produced harmful emissions. One of the promising alternatives is to produce biodiesel from waste economical feedstock such as chicken fat. Esterification and transesterification are used to create methyl ester from chicken fat. Then, 25%, 50%, 75%, and 100% of chicken oil biodiesel are volumetrically blended with diesel fuel. Diesel engine is loaded between 0% and 100% at 3000 rpm rated speed. Exergetic and exergoeconomic assessments of diesel engine fuelling with blends of chicken biodiesel were conducted in the present study. Diesel oil performed most efficiently in terms of exergy. For B100, the worst exergetic results are attained. The exergy efficiency of test engine at 75% engine load was 33.25% for the D100 and 27.85% for the B100. D100 produced the best exergoeconomic findings, while adding biodiesel to D100 made the exergoeconomic parameters worse. Crankshaft work had a particular exergy cost of 110.02 /GJ for B100 at 75% of engine output power. In the conclusion, it is noted that the waste chicken fat methyl ester can be used at low fractions as a substitute for traditional diesel fuel without modifying the engine, and this is a promising solution for waste management, turning waste products into an energy source, and dwindling fossil fuel reserves. © 2024 Elsevier Lt
Search for a Cp-Odd Higgs Boson Decaying Into a Heavy Cp-Even Higgs Boson and a Z Boson in the L+l-T(t)over and Ν(ν)over-Barb(b)over Final States Using 140 Fb-1 of Data Collected With the Atlas Detector
No full textA search for a heavy CP-odd Higgs boson, A, decaying into a Z boson and a heavy CP-even Higgs boson, H, is presented. It uses the full LHC Run 2 dataset of pp collisions at root s = 13TeV collected with the ATLAS detector, corresponding to an integrated luminosity of 140 fb(-1). The search for A -> ZH is performed in the l(+)l(-)t (t) over bar t and nu(nu) over barb (b) over bar final states and surpasses the reach of previous searches in different final states in the region with m(H) > 350 GeV and m(A) > 800 GeV. No significant deviation from the Standard Model expectation is found. Upper limits are placed on the production cross-section times the decay branching ratios. Limits with less model dependence are also presented as functions of the reconstructed m(t (t) over bar) and m(b (b) over bar) distributions in the l(+)l(-)t (t) over bar and nu(nu) over barb (b) over bar channels, respectively. In addition, the results are interpreted in the context of two-Higgs-doublet models
