Quality Driven Maintenance Policies for a Deteriorating System Subject To Non-Self Failures
No full textIn this study, we develop condition-based maintenance policies for a multi-state system subject to continuous-time Markovian deterioration that can result in non-self-announcing degradation including failure. Periodic inspections reveal the true state of the system; good, medium, poor, or failed. Upon receiving this piece of information, one of do-nothing, minor repair, major repair, fix repair, or replace maintenance actions is taken. On one hand, the system brings monetary rewards commensurate with system state-different rewards are earned per unit time spent in different states. On the other hand, quality loss that results from degraded system state is converted into monetary units-inspection and maintenance costs. Therefore, our objective is to determine the optimum inspection period and the corresponding maintenance policy that maximizes the expected long-run profit rate. We provide numerical examples to conduct sensitivity of the optimum inspection period and policy to system parameters, and to present the practical utility of our results
Search for Top-Philic Heavy Resonances in Pp Collisions at √s=13 Tev With the Atlas Detector
No full textAsearch for the associated production of a heavy resonance with a top-quark or a top-antitop-quark pair, and decaying into a t (t) over bar pair is presented. The search uses the vdata recorded by the ATLAS detector in pp collisions at root s = 13 TeV at the Large Hadron Collider during the years 2015-2018, corresponding to an integrated luminosity of 139 fb(-1). Events containing exactly one electron ormuon are selected. The two hadronically decaying top quarks from the resonance decay are reconstructed using jets clustered with a large radius parameter of R = 1. The invariant mass spectrum of the two top quark candidates is used to search for a resonance signal in the range of 1.0 TeV to 3.2 TeV. The presence of a signal is examined using an approach with minimal model dependence followed by a model-dependent interpretation. No significant excess is observed over the background expectation. Upper limits on the production cross section times branching ratio at 95% confidence level are provided for a heavy Z' boson based on a simplified model, for Z' mass between 1.0 TeV and 3.0 TeV. The observed (expected) limits range from 21 (14) fb to 119 (86) fb depending on the choice of model parameters.ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW, Austria; FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq, Brazil; FAPESP, Brazil; NSERC, Canada; NRC, Canada; CFI, Canada; CERN; ANID, Chile; CAS, China; MOST, China; NSFC, China; Minciencias, Colombia; MEYS CR, Czech Republic; DNRF, Denmark; DNSRC, Denmark; IN2P3-CNRS, France; CEA-DRF/IRFU, France; SRNSFG, Georgia; BMBF, Germany; HGF, Germany; MPG, Germany; GSRI, Greece; RGC, China; Hong Kong SAR, China; ISF, Israel; Benoziyo Center, Israel; INFN, Italy; MEXT, Japan; JSPS, Japan; CNRST, Morocco; NWO, Netherlands; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; JINR; MES of Russia; NRC KI, Russian Federation; MESTD, Serbia; MSSR, Slovakia; ARRS, Slovenia; MIZS, Slovenia; DSI/NRF, South Africa; MICINN, Spain; SRC, Sweden; Wallenberg Foundation, Sweden; SERI, Switzerland; SNSF, Switzerland; Canton of Bern, Switzerland; Canton of Geneva, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE, United States of America; NSF, United States of America; BCKDF, Canada; CANARIE, Canada; Compute Canada, Canada; CRC, Canada; COST, European Union; ERC, European Union; ERDF, European Union; Horizon 2020, European Union; Marie Sklodowska-Curie Actions, European Union; Investissements d'Avenir Labex, France; Investissements d'Avenir Idex, France; ANR, France; DFG, Germany; AvH Foundation, Germany; Herakleitos programme - EU-ESF, Greece; Thales programme - EU-ESF, Greece; Aristeia programme - EU-ESF, Greece; Greek NSRF, Greece; BSF-NSF, Israel; GIF, Israel; Norwegian Financial Mechanism 2014-2021, Norway; NCN, Poland; NAWA, Poland; La Caixa Banking Foundation, Spain; CERCA Programme Generalitat de Catalunya, Spain; PROMETEO Programme Generalitat Valenciana, Spain; GenT Programme Generalitat Valenciana, Spain; Goran Gustafssons Stiftelse, Sweden; Royal Society, United Kingdom; Leverhulme Trust, United KingdomWe thank CERN for the very successful operation of the LHC, as well as the support staff from our institutions without whom ATLAS could not be operated efficiently.

Design of the Onera M6 Wing by Shape Optimization Under Uncertainty
No full textAerodynamic shape optimization processes are often used for complex problems that meet single or multi-objective design requirements. The robust aerodynamic shape optimization techniques with a high number of design variables that consider uncertainties have a huge computational burden compared to the traditional aerodynamic shape optimization techniques without considering uncertainties. To overcome this issue, in this study, the proper orthogonal decomposition is integrated with the inductive design exploration method to use for the robust shape optimization of the ONERA M6 wing. The proper orthogonal decomposition method is utilized for reducing the number of design variables of the wing geometry. The cost due to the computational fluid dynamics analysis is mitigated by incorporating the proper orthogonal decomposition with a surrogate modeling technique called the radial basis function. The robust optimization is conducted by the proposed approach based on the inductive design exploration method by accounting for uncertainties of the Mach number in the transonic flow regime. The agreement between the performance predictions of the robust designs and the computational fluid dynamics analysis results showed the effectiveness of the proposed approach. © 2024 Gazi Universitesi Muhendislik-Mimarlik.

Community Education and Preparedness for Disaster Risk Reduction
No full textDisasters, which are rapidly increasing worldwide, have negative consequences due to the social, economic, and environmental impacts they create. Thus, disasters constitute a significant agenda due to their significant disruption of societal functioning and the inability of affected communities to cope with the adverse consequences by using their own resources. For sustainable and risk-informed development, engagement of all actors effectively in disaster risk reduction processes is of vital importance. Community involvement is central to these processes, thereby, devising methods to increase risk perception and developing positive outcome expectancy, self- and community efficacy, and skills for preparedness in communities are considered essential for strengthening risk reduction efforts. In this context, accompanied by investments in community education activities to foster necessary cognitions and behaviors for preparedness, it is also important to specifically target community engagement in disaster preparedness as part of disaster risk management. This chapter will focus on various theoretical models for disaster preparedness and research outcomes related to community education and engagement as well as provide a discussion of methods for the training of community members
Müon Çarpıştırıcılarında İkinci Aile Bağlantılı Yüklü Vektör-benzeri Leptonların Aranması
No full textVektör benzeri leptonlar (VBL), E6 Büyük Birleşim Teorisi ve Çeşni Demokrasisi Hipotezi kapsamında öngörülmektedir ve Standart Model'deki (SM) kütle hiyerarşisi gibi sorulara cevap verebilir. Müon çarpıştırıcıları, ulaşılabilir kütle merkezi enerjisi, ışınlık ve hassasiyet açısından VBL'lerin tespitinde avantaj sağlayabilir. LEP deneylerinde yüklü VBL'lerin kütle sınırı 101,2 GeV olarak belirlenmiştir. Bu tezde, ikinci SM ailesi leptonlarıyla bağlantılı yüklü VBL'lerin 3-6-10-14 TeV kütle merkezi enerjilerine sahip müon çarpıştırıcılarında gözlenme olasılıkları, tesir kesitleri hesaplanarak incelenmiştir. Çift üretimde kinematik limit civarındaki kütlelere kadar (1,5-3-5-7 TeV), tek üretimde ise karışım açısı değeri 0.0035'ten büyükse kütle merkezi enerjisine yakın kütlelere kadar 2. nesil yüklü VBL'lerin araştırılabileceği sonucuna varılmıştır. Tek üretimde VBL'lerin tespiti durumunda karışım açısı 0.0035'ten büyükse belirlenebilecektir. Müon çarpıştırıcılarında çift üretim için 6-10-14 TeV kütle merkezi enerjili seçenekler ve tek üretim için ele alınan tüm kütle merkezi enerjilerinde yüklü VBL kütlesinin LHC'de ulaşılan kütle limitlerinin çok daha üzerine kadar taranabileceği görülmüştür.Vector-like leptons (VBLs) are predicted by the E6 Grand Unified Theory and the Flavor Democracy Hypothesis, and they can potentially address issues such as the mass hierarchy in the Standard Model (SM). Muon colliders offer advantages in the detection of VBLs due to their achievable center-of-mass energy, luminosity, and precision. The mass limit for charged VBLs was determined to be 101.2 GeV in LEP experiments. This thesis investigates the detection probabilities of charged VBLs associated with the second SM family leptons at muon colliders with center-of-mass energies of 3-6-10-14 TeV, by calculating the cross sections. It was found that in pair production, masses up to the kinematic limit (1.5-3-5-7 TeV) can be probed, while in single production, second-generation charged VBLs can be investigated up to near the center-of-mass energy for mixing angles greater than 0.0035. If VBLs are detected in single production, the mixing angle will be determined if it is greater than 0.0035. For muon colliders, pair production at center-of-mass energies of 6-10-14 TeV and single production at all investigated energies can probe charged VBL masses significantly beyond the mass limits reached by the LHC
A New Perspective for Nanoconfined Polymer Crystals
No full textIX. Polymer Science and Technology Congress with International Participation 16-18 September 2024, Ankara METU Culture and Convention CenterNanoporous hard templates provide a two-dimensional confined space in which self- organization processes such as crystallization, protein secondary structure formation, and phase separation can be fundamentally different from those obtained in thin films and in bulk. A particular advantage of hard templates is that they provide a range of parameter space (pore diameter, curvature, nature of pore walls) that can induce or manipulate nucleation and crystal growth. Nowadays, a broad range of soft materials can be formed into nanotubes utilizing nanoporous hard templates containing arrays of self-ordered cylindrical nanopores. Understanding the crystallization, thermodynamics, and dynamics of soft materials under confinement allows for their rational design as functional devices with tunable mechanical strength, processability, and electronic and optical properties. The principal focus of this lecture is finding the basic underlying principles that give rise to nucleation and crystal growth in a range of soft materials (crystallizable polymers, amphiphilic molecules, liquid crystals, low-molecular-weight liquids, and biopolymers) under hard confinement. The confining geometry is also important since curvature affects Laplace pressure. In this context, we provide a detailed analysis of the impact of compartmentalization, space, curvature, interfacial interaction, and molecular weights on the nano-crystallization process
Search for Pair Production of Higgsinos in Events With Two Higgs Bosons and Missing Transverse Momentum in Formula Presented Formula Presented Collisions at the Atlas Experiment
No full textThis paper presents a search for pair production of higgsinos, the supersymmetric partners of the Higgs bosons, in scenarios with gauge-mediated supersymmetry breaking. Each higgsino is assumed to decay into a Higgs boson and a nearly massless gravitino. The search targets events where each Higgs boson decays into Formula Presented, leading to a reconstructed final state with at least three energetic Formula Presented-jets and missing transverse momentum. Two complementary analysis channels are used, with each channel specifically targeting either low or high values of the higgsino mass. The low-mass (high-mass) channel exploits Formula Presented of Formula Presented data collected by the ATLAS detector during Run 2 of the Large Hadron Collider. No significant excess above the Standard Model prediction is found. At 95% confidence level, masses between 130 GeV and 940 GeV are excluded for higgsinos decaying exclusively into Higgs bosons and gravitinos. Exclusion limits as a function of the higgsino decay branching ratio to a Higgs boson are also reported. © 2024 CERN, for the ATLAS Collaboration.Australian Research Council, ARC; Centre National pour la Recherche Scientifique et Technique, CNRST; Fundação para a Ciência e a Tecnologia, FCT; Cooperative Research Centres, Australian Government Department of Industry, CRCs; National Science Foundation, NSF; Science and Technology Facilities Council, STFC; H2020 Marie Skłodowska-Curie Actions, MSCA; Nederlandse Organisatie voor Wetenschappelijk Onderzoek, NWO; Ministry of Science and Technology, Taiwan, MOST; Israel Science Foundation, ISF; Leverhulme Trust; Baden-Württemberg Stiftung, BWS; Neubauer Family Foundation, NFF; Staatssekretariat für Bildung, Forschung und Innovation, SBFI; Javna Agencija za Raziskovalno Dejavnost RS, ARRS; Generalitat de Catalunya; Bundesministerium für Wissenschaft, Forschung und Wirtschaft, BMWFW; Austrian Science Fund, FWF; Agencia Nacional de Investigación y Desarrollo, ANID; Bundesministerium für Bildung und Forschung, BMBF; Helmholtz-Gemeinschaft, HGF; Danmarks Grundforskningsfond, DNRF; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq; Karlsruhe Institute of Technology, KIT; Canarie; Göran Gustafssons Stiftelser; European Commission, EC; Ministarstvo Prosvete, Nauke i Tehnološkog Razvoja, MPNTR; U.S. Department of Energy, USDOE; European Cooperation in Science and Technology, COST; International Council of Shopping Centers, ICSC; Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP; Institutul de Fizică Atomică, IFA; Natural Sciences and Engineering Research Council of Canada, NSERC; Nella and Leon Benoziyo Center for Neurological Diseases, Weizmann Institute of Science; Irish Rugby Football Union, IRFU; Chinese Academy of Sciences, CAS; Defence Science Institute, DSI; Agencia Nacional de Promoción Científica y Tecnológica, ANPCyT; Minerva Foundation; National Research Foundation, NRF; Royal Society of South Australia, RSSA; Generalitat Valenciana, GVA; CERN; Ministerstvo Školství, Mládeže a Tělovýchovy, MŠMT; National Research Council Canada, NRC; Brookhaven National Laboratory, BNL; Alexander von Humboldt-Stiftung, AvH; Multiple Sclerosis Scientific Research Foundation, MSSRF; Caring Futures Institute, Flinders University, CFI; British Columbia Knowledge Development Fund, BCKDF; Ministry of Education, Culture, Sports, Science and Technology, MEXT; National Natural Science Foundation of China, NSFC: NSFC 12275265, 12175119; National Natural Science Foundation of China, NSFC; 21/SCI/017; Fondo Nacional de Desarrollo Científico y Tecnológico, FONDECYT: 1230987, 1210400, 1190886; Fondo Nacional de Desarrollo Científico y Tecnológico, FONDECYT; Narodowe Centrum Nauki, NCN: NCN 2021/42/E/ST2/00350, NCN UMO-2019/34/E/ST2/00393, UMO-2021/40/C/ST2/00187, UMO-2020/37/B/ST2/01043, 2022/47/B/ST2/03059; Narodowe Centrum Nauki, NCN; Norges Forskningsråd: RCN-314472; Norges Forskningsråd; IN2P3-CNRS; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF: RPG-2020-004, SNSF—PCEFP2_194658; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF; Horizon 2020 Framework Programme, H2020: CHIST-ERA-19-XAI-00; Horizon 2020 Framework Programme, H2020; CC-IN2P3; Instituto Nazionale di Fisica Nucleare, INFN: 754496; Instituto Nazionale di Fisica Nucleare, INFN; Japan Society for the Promotion of Science, JSPS: JP21H05085, JP22H04944, 22H01227; Japan Society for the Promotion of Science, JSPS; Vetenskapsrådet, VR: VR 2022-03845; Vetenskapsrådet, VR; Deutsche Forschungsgemeinschaft, DFG: DFG—CR 312/5-1; Deutsche Forschungsgemeinschaft, DFG; CIDEGENT/2019/027, CIDEGENT/2019/023; Narodowa Agencja Wymiany Akademickiej, NAWA: PPN/PPO/2020/1/00002/U/00001; Narodowa Agencja Wymiany Akademickiej, NAWA; European Regional Development Fund, ERDF: IDIFEDER/2018/048, LCF/BQ/PI20/11760025; European Regional Development Fund, ERDF; SCI/013; 101033496; Agence Nationale de la Recherche, ANR: ANR-20-CE31-0013, ANR-11-LABX-0012, ANR-21-CE31-0022; Agence Nationale de la Recherche, ANR; Ministerio de Ciencia e Innovación, MCIN: RYC2019-028510-I, RYC2020-030254-I; Ministerio de Ciencia e Innovación, MCIN; Fundación BBVA, FBBVA: LEO22-1-603; Fundación BBVA, FBBVA; 2014-2021; Knut och Alice Wallenbergs Stiftelse: KAW 2017.0100, KAW 2018.0157, KAW 2019.0447; Knut och Alice Wallenbergs Stiftelse; Center for Advancing Research Impact in Society, ARIS: J1-3010; Center for Advancing Research Impact in Society, ARIS; European Research Council, ERC: ERC—948254; European Research Council, ER
Açık-döngü Fiber Optik Dönüölçer Sistemi Geliştirilmesi ve Göreceli Yoğunluk Gürültüsü Analizi
No full textFiber optik dönüölçer sistemleri özellikle yüksek hassasiyet ve doğruluk gerektiren uygulamalarda, örneğin askeri platformlarda, havacılık ve navigasyon sistemlerinde yaygın olarak kullanılmaktadır. Bu tez çalışmasında, açık döngü bir fiber optik dönüölçer sisteminin geliştirilmesi ve bu sistemlerdeki göreceli yoğunluk gürültüsü analizine odaklanılmıştır. Navigasyon seviyedeki bir fiber optik dönüölçer sistemi deneysel ve simülasyon ortamında kurulmuş ve elde edilen sonuçlar incelenmiştir. Kurulan fiber optik dönüölçer sisteminde yaklaşık olarak 1 km uzunluğunda fiber sarım bulunmakta ve benzetim çalışmalarının deneysel sisteme uygun olarak optimize edilmiştir. Simülasyon çalışmaları, VPI Photonics yazılımı kullanılarak gerçekleştirilmiştir. VPI Photonics, optik ve fotonik sistemlerin tasarımı ve analizi için güçlü bir simülasyon platformu sunmaktadır. Bu çalışmada, fiber optik dönüölçerlerde yaygın olarak kullanılan yükseltilmiş kendiliğinden emisyonlu ışık kaynağı tasarımları oluşturulmuş ve farklı konfigürasyonlar ile elde edilen simülasyon ve deneysel sonuçlar incelenmiştir. Farklı ışık kaynağı tasarımlarının göreceli yoğunluk gürültüsü üzerindeki etkileri de incelenmiştir. Bu gürültü analizlerinde, sistemde kullanılan ışık kaynağının optik spektral bant genişliğinin gürültü seviyesine etkisi incelenmiş ve elde edilen sonuçlar teorik hesaplamalarla desteklenmiştir. Daha sonra açık döngü bir fiber optik dönüölçer tasarımı yapılarak simülasyon ve deneysel sistem modelleri hazırlanmıştır. Dünya dönü hızlarının algılanması için sensör biriminin farklı açısal konumlandırılması göre 0 derece/saat ile 15 derece/saat hız aralığında ölçümler yapılmış ve elde edilen sonuçlar analiz edilmiştir. Laboratuvar ortamında optik masa üzerinde yapılan deneysel dünya dönüsü testleri ile simülasyon modeli sonuçlarının büyük oranda uyuştuğu gözlemlenmiştir. Daha sonra fiber optik dönüölçer performansını belirleyen bir değer olan açısal rastgele yürüyüş katsayısını iyileştirilmesine yönelik çalışmalar yapılmıştır. Bu değeri etkileyen en önemli faktörlerden biri de sistemdeki ışık kaynağının göreceli yoğunluk gürültüsüdür. Fiber optik dönüölçer sistemlerinin performansını etkileyen göreceli yoğunluk gürültüsünü düşürmek için yarı iletken optik amplifikatörler kullanılarak yenilikçi bir ışık kaynağı tasarımı yapılmış ve sistem performansı üzerindeki etkileri incelenmiştir. Gürültü düşürme yapılmamış ışık kaynağı ve gürültü seviyesi düşürülmüş ışık kaynağının testleri laboratuvar ortamında uzun süreli veri toplayarak gerçekleştirilmiş ve elde edilen sonuçlar analiz edilerek fiber optik dönüölçer sisteminin performansında önemli iyileştirmeler yapılmıştır.Fiber optic gyroscope systems are widely used in applications requiring high precision and accuracy, such as military platforms, aviation, and navigation systems. This thesis focuses on the development of an open-loop fiber optic gyroscope system and the analysis of relative intensity noise in these systems. A navigation-grade fiber optic gyroscope system was established in an experimental and simulation environment and the obtained results were examined. The established fiber optic gyroscope system has approximately 1 km of fiber coil and the simulation studies were optimized by the experimental system. Simulation studies were performed using VPI Photonics software. VPI Photonics offers a powerful simulation platform for the design and analysis of optical and photonic systems. In this study, amplified spontaneous emission light source designs, widely used in fiber optic gyroscopes, were established, and simulation and experimental results with different configurations were examined. The effects of varying light source designs on relative intensity noise were also investigated. In these analyses, the impact of the optical spectral bandwidth of the light source on the noise level was investigated and the obtained results were supported by theoretical calculations. Then, an open-loop fiber optic gyroscope design was built, and simulation and experimental system models were prepared. In order to detect the Earth's rotation speeds, measurements were made between 0 degrees/hour and 15 degrees/hour according to different angular positioning of the sensor unit, and the obtained results were analyzed. It was observed that the experimental Earth rotation tests performed on the optical table in the laboratory environment and the simulation model results were largely similar. Later, studies were carried out to improve the angular random walk coefficient, which is a value that determines the performance of the fiber optic gyroscope. One of the most important factors affecting this value is the relative intensity noise of the light source in the system. An innovative light source design was made using semiconductor optical amplifiers to reduce the relative intensity noise affecting the performance of fiber optic gyroscope systems and its effects on the system performance were investigated. The tests of the light source without noise reduction and the light source with reduced noise level were carried out by collecting long-term data in the laboratory environment and the obtained results were analyzed and significant improvements were made in the performance of the fiber optic gyroscope system
