Nucleolus Based Cost Allocation Methods for a Class of Constrained Lane Covering Games
No full textOner, Nihat/0000-0002-8067-224XIn truckload transportation procurement networks, shippers purchasing the services of truckload carriers seek to form multi-company tours which consist of regularly scheduled shipments with minimal empty truck movements with the aim of getting better rates from the carriers in return. Identifying the minimum cost collaborative solution and sharing the costs in a fair manner are two interrelated and critical tasks for the success of such networks. The restrictions on the tours which can be formed make both of these tasks very challenging. In this paper, we take a cooperative game theory approach and study the resulting constrained lane covering game. We first show the set of conditions which must be satisfied for the game to have a non -empty core. We propose nucleolus based cost allocation methods. We also develop column and row generation methods for solving these mathematical models. We compare our proposed cost allocation models with alternative cost allocation methods and each other using a set of core stability metrics through computational experiments on randomly generated instances from the literature.Scientific and Technological Research Council of Turkey (TUBITAK) [112M227]Acknowledgment The research presented in this paper was partially supported by the Scientific and Technological Research Council of Turkey (TUBITAK) through grant 112M227
An Analysis of the Transformation of Public Space Designs in Architecture /
No full textSince ancient Greece, users can create public and private spheres with the architectural spaces they produce by taking action. It can be claimed that the concept of the public sphere has undergone changes and transformations with various factors in historical processes. At this point, this thesis explores the conditions that make up the public sphere and the architectural/spatial discussions on the production of public space in the context of the factors affecting social life by creating breaks in historical processes within the framework of the view and evaluation of events by thinkers and architects. In this context, this study presents research on the existence and qualities of public space. In this study, in the context of the historical reading process and the conditions affecting the existing social structure, the current state of the public space and its content on architectural thoughts and practices are discussed. It is a study based on the program/action and structural qualities of the architectural content of the public space through the events, thinkers, and architects determined at this point. The study analyzes the changes and transformations in design and structural elements, such as the sizes of public spaces, ground-surface relations, and interactions of architectural elements. In this context, the thesis uses three primary methods: literature research, tabulation, and comparative analysis. The first method that constitutes the study is the literature search on how the definition and content of the public sphere in philosophy are created. With this method, the concept and definitions of public sphere of the thinkers Hannah Arendt, Jürgen Habermas, Richard Sennett, Oskar Negt-Alexander Kluge, Henri Lefebvre, Jacques Derrida and William Gibson were reached. The second research method of the study is analysis and classification. In the first part of the research, the definitions and expansions of the public sphere and the public space programs and contents pointed out by the selected thinkers were examined. In the period determined by the discourses of these thinkers and the definitions of the public sphere, the practices of space to produce public space in the context of the works of architects such as Herman Hertzberger, Rem Koolhaas, Bernard Tschumi, Marcos Novak, and Bjarke Ingels were also examined. As a result of this research and analysis process, the technological, political, economic, artistic, health, social and architectural changes that change the historical methods and the intellectual and practical counterparts of the architectural content that establishes the public space are brought together with tabulation. The last method of the study is a process for designing contemporary images of public space. It includes a method to define and discuss the architectural contents of the public space of conditions affecting the social structure, such as climate change, the Covid-19 pandemic, economic and political changes, and technological developments, which are included in the current conditions that emerged during the analysis process of the tabulation. Thus, the factors affecting the design and production of public space in today's architectural thoughts and practices, architectural programs, intellectual and structural elements in the production of public space, and how the public space will be formed are discussed through understanding the present and the near future.Antik Yunan'dan itibaren kullanıcılar eylemde bulunarak ürettiği mimari mekanlar ile kamusal ve özel alanlar oluşturabilirler. Kamusal alan kavramının ise tarihsel süreçlerdeki çeşitli faktörler ile değişim ve dönüşümlere uğradığı iddia edilebilir. Bu noktada bu tez tarihsel süreçlerde kırılmalar yaratarak toplumsal yaşantıyı etkileyen faktörler bağlamında, düşünürler ve mimarların olaylara bakış ve değerlendirmeleri çerçevesinde kamusal alanı oluşturan koşulları ve kamusal mekanın üretilmesine yönelik mimari/mekansal tartışmaları araştırmaktadır. Bu kapsamda bu çalışma kamusal mekanın varlığı ve nitelikleri üzerine bir araştırma sunmaktadır. Bu çalışmada tarihsel okuma süreci ile mevcut toplumsal yapıyı etkileyen koşullar bağlamında, kamusal mekanın güncel halini ve mimari düşünce ve pratiklerine yönelik içeriği tartışılmaktadır. Bu noktada belirlenen olaylar, düşünürler ve mimarlar ile kamusal mekanın mimari içeriğinin program/eylem ve yapısal nitelikleri üzerine kurulu bir çalışmadır. Çalışma kamusal mekanların büyüklükleri, zemin-yüzey ilişkileri, mimari elemanların etkileşimleri gibi tasarımsal ve yapısal unsurlardaki değişimleri ve dönüşümleri analiz etmektedir. Bu bağlamda tez literatür araştırması, tablolama ve karşılaştırmalı analiz gibi üç temel yöntem kullanır. Çalıştırmayı oluşturan birinci yöntem felsefede kamusal alan tanım ve içeriğinin nasıl oluşturulduğuna yönelik literatür araştırmasıdır. Bu yöntem ile tezde yer verilen düşünürler Hannah Arendt, Jürgen Habermas, Richard Sennett, Oskar Negt-Alexander Kluge, Henri Lefebvre, Jacques Derrida ve William Gibson'ın kamusal alan kavramı ve tanımlarına ulaşılmıştır. Çalışmanın ikinci araştırma yöntemi ise analiz ve sınıflandırmadır. Araştırmanın ilk bölümünde seçilen düşünürlerin kamusal alan tanımları ve açılımları ile işaret ettikleri kamusal mekan programları ve içerikleri incelenmiştir. Bu düşünürlerin söylemleri ve kamusal alan tanımları ile belirlenen dönem içerisinde Herman Hertzberger, Rem Koolhaas, Bernard Tschumi, Marcos Novak ve Bjarke Ingels gibi mimarların çalışmaları bağlamında kamusal mekanı üretmeye yönelik mekan pratikleri de incelenmiştir. Bu araştırma ve analiz sürecinin sonucunda ise tarihsel süreçleri değiştiren teknolojik, politik, ekonomik, sanat, sağlık, sosyal ve mimari değişimler ile kamusal mekanı kuran mimari içeriğin düşünsel ve pratik karşılıkları tablolama ile bir araya getirilmiştir. Çalışmanın son yöntemi ise kamusal mekanın güncel karşılıklarını tasarlamaya yönelik bir süreçtir. Yapılan tablolamanın analiz sürecinde ortaya çıkan güncel koşulların barındırdığı iklim değişikliği, Covid-19 pandemisi, ekonomik ve politik değişimler ve teknolojik gelişmeler gibi toplumsal yapıyı etkileyen koşulların kamusal mekanın mimari içeriklerini tanımlamaya ve tartışmaya yönelik bir süreci içerir. Böylece günümüz mimari düşünce ve pratiklerinde kamusal mekanın tasarım ve üretimini etkileyen faktörler, mimari programlar ve kamusal mekanın üretilmesindeki düşünsel ve yapısal etkenler ile kamusal mekanın nasıl oluşacağı, bugünü ve yakın geleceği anlamak üzerinden tartışılmıştır

Pidram: a Holistic End-To Fpga-Based Framework for Processing-In
No full textCommodity DRAM-based processing-using-memory (PuM) techniques that are supported by off-the-shelf DRAM chips present an opportunity for alleviating the data movement bottleneck at low cost. However, system integration of these techniques imposes non-trivial challenges that are yet to be solved. Potential solutions to the integration challenges require appropriate tools to develop any necessary hardware and software components. Unfortunately, current proprietary computing systems, specialized DRAM-testing platforms, or system simulators do not provide the flexibility and/or the holistic system view that is necessary to properly evaluate and deal with the integration challenges of commodity DRAM-based PuM techniques. We design and develop Processing-in-DRAM (PiDRAM), the first flexible end-to-end framework that enables system integration studies and evaluation of real, commodity DRAM-based PuM techniques. PiDRAM provides software and hardware components to rapidly integrate PuM techniques across the whole system software and hardware stack. We implement PiDRAM on an FPGA-based RISC-V system. To demonstrate the flexibility and ease of use of PiDRAM, we implement and evaluate two state-of-the-art commodity DRAMbased PuM techniques: (i) in-DRAM copy and initialization (RowClone) and (ii) in-DRAM true random number generation (D-RaNGe). We describe how we solve key integration challenges to make such techniques work and be effective on a real-system prototype, including memory allocation, alignment, and coherence. We observe that end-to-end RowClone speeds up bulk copy and initialization operations by 14.6x and 12.6x, respectively, over conventional CPU copy, even when coherence is supported with inefficient cache flush operations. Over PiDRAM's extensible codebase, integrating both RowClone and D-RaNGe end-to-end on a real RISC-V system prototype takes only 388 lines of Verilog code and 643 lines of C++ code.Semiconductor Research Corporation; ETH Future Computing LaboratoryWe thank the reviewers of MICRO 2021, HPCA 2022, and TACO for feedback.

Dialogue Between Architecture and Material Sciences for Sustainable Urban Ecosystems: Biodegradable Polymer Plastic Seed Capsule Production Process for Porous Concrete Structures
No full textThe presented study introduces an interdisciplinary and inter-scale collaborative research project of the Department of Material Science and Nanotechnology Engineering and the Department of Architecture. The main objective of the project is to investigate appropriate methods of developing polymer capsules made of upcycled waste plastics for plant seeds, which are to place in permeable/porous concrete mixture. Furthermore, we plan to modify recycled plastic to make it biodegradable. Porous concrete is a special type of concrete with a high permeability rate due to its material composition. It is composed of narrowly-graded course aggregate, cement or cementitious materials, and water. It does not include sand. Therefore, it is able to transmit water and air because of its inner voids, 15-35% compared to conventional concrete. The voids are considered for seed capsules. The teams of Material Science and Nanotechnology Engineering and Architecture discussed and elaborated on the issues and problems of developing waste plastic upcycling for biodegradable seed capsules in porous concrete. The recycling of waste plastic, thermal conditions of porous concrete during curing, uniformity, controllability, versatility, mass-productivity, high efficiency, and reproductivity of polymer encapsulation methods for properly scaled dimensions have been considered. The process has been formulated but could not have been tested due to the pandemic. It is planned to carry out the project in early 2022. It is our utmost concern to initiate projective and experimental research for innovate technological advancement and know-how to introduce, develop and settle new, smart, resilient, and sustainable human-nature ecosystems and biodiversity by means of creative dialogue/collaboration among various disciplines and professions
Constraints on Higgs Boson Production With Large Transverse Momentum Using H -> B(b)over-Bar Decays in the Atlas Detector
No full textThis paper reports constraints on Higgs boson production with transverse momentum above 1 TeV. The analyzed data from proton-proton collisions at a center-of-mass energy of 13 TeV were recorded with the ATLAS detector at the Large Hadron Collider from 2015 to 2018 and correspond to an integrated luminosity of 136 fb(-1.) Higgs bosons decaying into b (b) over bar are reconstructed as single large-radius jets recoiling against a hadronic system and are identified by the experimental signature of two b-hadron decays. The experimental techniques are validated in the same kinematic regime using the Z -> b (b) over bar process. The 95% confidence-level upper limit on the cross section for Higgs boson production with transverse momentum above 450 GeV is 115 fb, and above 1 TeV it is 9.6 fb. The Standard Model cross section predictions for a Higgs boson with a mass of 125 GeV in the same kinematic regions are 18.4 fb and 0.13 fb, respectively.ANPCyT, Argentina; YerPhI, Armenia; ARC, Australia; BMWFW, Austria; FWF, Austria; ANAS, Azerbaijan; SSTC, Belarus; CNPq, Brazil; FAPESP, Brazil; NSERC, Canada; CFI, Canada; NSFC, China; MEYS CR, Czech Republic; DNRF, Denmark; DNSRC, Denmark; IN2P3-CNRS, France; CEA-DRF/IRFU, France; BMBF, Germany; MPG, Germany; Hong Kong SAR, China; ISF, Israel; Benoziyo Center, Israel; INFN, Italy; MEXT, Japan; JSPS, Japan; CNRST, Morocco; RCN, Norway; MEiN, Poland; FCT, Portugal; MNE/IFA, Romania; NRC KI, Russian Federation; MESTD, Serbia; MSSR, Slovakia; ARRS, Slovenia; MIZS, Slovenia; MICINN, Spain; SRC, Sweden; Wallenberg Foundation, Sweden; SNSF, Switzerland; MOST, Taiwan; TAEK, Turkey; STFC, United Kingdom; DOE, United States of America; NSF, United States of America; BCKDF, Canada; CANARIE, Canada; CRC, Canada; COST, European Union; ERDF, European Union; Marie Sklodowska-Curie Actions, European Union; Investissements d'Avenir Labex, France; ANR, France; DFG, Germany; AvH Foundation, Germany; BSF-NSF, Israel; GIF, Israel; Norwegian Financial Mechanism 2014-2021, Norway; NCN, Poland; La Caixa Banking Foundation, Spain; CERCA Programme Generalitat de Catalunya, Spain; Generalitat Valenciana, Spain; Goran Gustafssons Stiftelse, Sweden; Royal Society, United Kingdom; Leverhulme Trust, United Kingdom; NRC, Canada; CERN; ANID, Chile; CAS, China; MOST, China; Minciencias, Colombia; SRNSFG, Georgia; HGF, Germany; GSRI, Greece; RGC, China; NWO, Netherlands; JINR; MES of Russia, Russian Federation; DSI/NRF, South Africa; SERI, Switzerland; Canton of Bern, Switzerland; Canton of Geneva, Switzerland; Compute Canada, Canada; ERC, European Union; Horizon 2020, European Union; Investissements d'Avenir Idex, France; Greek NSRF, Greece; Herakleitos programme - EU-ESF, Greece; Thales programme - EU-ESF, Greece; Aristeia programme - EU-ESF, Greece; NAWA, PolandWe thank CERN for the very successful operation of the LHC, aswell as the support staff fromour institutionswithout whom ATLAS could not be operated efficiently.

The Association Between Commuting, Mood and Job Performance: the Structural Equation Modelling Approach
No full textCommuting demands a considerable amount of time from a worker's daytime. Numerous studies have shown the relationship between commuting and mood, and even job performance. Contradictory findings are also present in the literature regarding the association between commuting, mood and job performance. Therefore, the aim of the present study is to examine the association between commuting, negative upon arrival at work and individual job performance, given the special focus on the mediating role of negative mood. Two hundred and twenty-six participants were recruited via snowball sampling. Participants were asked to answer questions about commute duration and distance, to rate their mood upon arrival at work and to fill in the individual work performance questionnaire. Results showed that commute duration and distance was associated with job performance through mood upon arrival at work. It is believed that this study provides valuable information regarding the mediating role of mood upon arrival at work
Radiofrequency Catheter Ablation of Patients With Permanent Junctional Reciprocating Tachycardia and Long-Term Follow-Up Results
No full textBackground Permanent junctional reciprocating tachycardia (PJRT) is an infrequent form of atrioventricular re-entrant tachycardia. We report the clinical and electrophysiological properties of PJRT and outcomes of radiofrequency catheter ablation (RCA) in a large group of patients. Methods We included 62 patients with the diagnosis of PJRT. Radiofrequency catheter ablation was performed in all. Results Location of accessory pathway was right posteroseptal in 37 (59,7%) cases, right midseptal in 3 (4,8%), left posterior in 7 (11,3%), left lateral in 5 (8,1%), left posterolateral in 3 (4,8%), left anterolateral in 2 (3,2%), left posteroseptal in 2 (3,2%), middle cardiac vein in 2 (3,2%), and left coronary cusp in 1 (1,6%). Single procedure success rate was 90.3%. None of patients had recurrence during follow-up after repeat ablations. Overall long-term success rate was 98.4%. Left ventricular systolic function recovered in all patients with tachycardia-induced cardiomyopathy (TIC). Conclusion Retrograde decremental accessory pathways are mainly located in posteroseptal region. Radiofrequency catheter ablation is a safe and effective approach in patients with PJRT
Performance Analysis of Feature Sets for Harmonic Radar To Classify Electronic Devices
No full text6th International Symposium on Multidisciplinary Studies and Innovative Technologies, ISMSIT 2022 -- 20 October 2022 through 22 October 2022 -- 184355In this study, we exploit new feature sets to classify electronic devices via harmonic radar. Nonlinear characteristics of the devices are recorded as a response to a frequency-swept signal with constant power. The harmonic characteristics of electronic devices are described by statistical and Fourier feature sets. Contrary to previous studies, statistical and Fourier feature sets are composed of both feature parameters and harmonic information. Exploiting these feature sets provides a good baseline for performance comparison rather than analyzing the classification performance of the harmonics individually. The performance assessment is performed by Monte Carlo simulations. © 2022 IEEE
Choroidal Vascular Index in Patients With Attention-deficit/Hyperactivity Disorder and Methylphenidate
No full textArticle; Early AccessPurpose:To investigate choroidal vascularity in children with attention-deficit/hyperactivity disorder (ADHD) who were not receiving therapy, children with ADHD who were regularly taking methylphenidate (MPH), and healthy controls.Methods: The study included three groups: patients with newly diagnosed ADHD without treatment, patients diagnosed as having ADHD who were already being treated with oral MPH, and controls. Both choroidal vascularity index (CVI) and choroidal thickness were measured using an enhanced-depth imaging mode of spectral-domain optical coherence tomography (EDIOCT) (Spectralis; Heidelberg Engineering GmbH).Results: There was a significant difference in CVI and stromal area between groups. Post-hoc univariate analysis showed that CVI was significantly lower in patients with ADHD treated with MPH compared with the other groups (P .001, for each); however, there was no difference between the treatment-free ADHD group and controls (P = .305). In contrast, stromal area was significantly higher in patients with ADHD treated with MPH than the other groups (P .001, for each group). The correlation of CVI with MPH treatment duration in patients with ADHD treated with MPH showed a significant, moderate negative correlation (P = .01, r = - 0.66).Conclusions: CVI is reduced in patients with ADHD treated with MPH, and the decrease in CVI becomes significant with increasing duration of MPH treatment. This result reflects an indirect effect of MPH treatment on choroidal vascular structures.[J Pediatr Ophthalmol Strabismus. 20XX;X(X):XX-XX.
