spread across the United States, forcing cities to impose stay-at-home and shelter-in-place orders. Building operations had to adjust as non-essential personnel worked from home. But as buildings prepare for personnel to return, they need to plan for safe operations amid new COVID-19 guidelines. In this paper we propose a methodology for capacity and flow modeling of personnel within buildings to safely operate under COVID-19 guidelines. We model personnel flow within buildings by network flows with queuing constraints. We study maximum flow, minimum cost, and minimax objectives. We compare our network flow approach with a simulation model through a case study and present the results. Our results showcase various scenarios of how buildings could be operated under new COVID-19 guidelines and provide a framework for building operators to plan and operate buildings in this new paradigm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=network%20analysis" title="network analysis">network analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20simulation" title=" building simulation"> building simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19 "> COVID-19 </a> </p> <a href="https://publications.waset.org/abstracts/128718/building-capacity-and-personnel-flow-modeling-for-operating-amid-covid-19" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128718.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> An Assembly Line Designing Study for a Refrigeration Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emin%20Gundogar">Emin Gundogar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Erkayman"> Burak Erkayman</a>, <a href="https://publications.waset.org/abstracts/search?q=Aysegul%20Yilmaz"> Aysegul Yilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusret%20Sazak"> Nusret Sazak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When considering current competition conditions on the world, satisfying customer demands on time has become an important factor that enables the firms take a step further.

Selcuk Gecim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the article, the main goal is to study the effect of the plasmonic properties on the photocurrent generated by a photodetector. Fundamentally, a typical photodetector is designed and simulated using the finite element methods. To utilize the plasmonic effect, gold nanoparticles with different shape, size and morphology are buried into the intrinsic region. Plasmonic effect is arisen through the interaction of the incoming light with nanoparticles by which electrical properties of the photodetector are manipulated. In fact, using plasmonic nanoparticles not only increases the absorption bandwidth of the incoming light, but also generates a high intensity near-field close to the plasmonic nanoparticles. Those properties strongly affect the generated photocurrent. The simulation results show that using plasmonic nanoparticles significantly enhances the electrical properties of the photodetectors. More importantly, one can easily manipulate the plasmonic properties of the gold nanoparticles through engineering the nanoparticles' size, shape and morphology. Another important phenomenon is plasmon-plasmon interaction inside the photodetector. It is shown that plasmon-plasmon interaction improves the electron-hole generation rate by which the rate of the current generation is severely enhanced. This is the key factor that we want to focus on, to improve the photodetector electrical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=plasmonic%20photodetector" title="plasmonic photodetector">plasmonic photodetector</a>, <a href="https://publications.waset.org/abstracts/search?q=plasmon-plasmon%20interaction" title=" plasmon-plasmon interaction"> plasmon-plasmon interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Gold%20nanoparticle" title=" Gold nanoparticle"> Gold nanoparticle</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20properties" title=" electrical properties"> electrical properties</a> </p> <a href="https://publications.waset.org/abstracts/125857/photodetector-engineering-with-plasmonic-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125857.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Continuous Manufacturing of Ultra Fine Grained Materials by Severe Plastic Deformation Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asl%C4%B1%20G%C3%BCnay%20Bulutsuz">Aslı Günay Bulutsuz</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Emin%20Yurci"> Mehmet Emin Yurci</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Severe plastic deformation techniques are top-down deformation methods which enable superior mechanical properties by decreasing grain size. Different kind severe plastic deformation methods have been widely being used at various process temperature and geometries. Besides manufacturing advantages of severe plastic deformation technique, most of the types are being used only at the laboratory level. They cannot be adapted to industrial usage due to their continuous manufacturability and manufacturing costs.

In addition, Hopf bifurcation point detection was performed to show the effect of MGs on the system loadability margin. In the study results, it is seen that MGs affect system stability positively by increasing system loadability margin and has a damper effect on the critical modes of the system and the electromechanical local modes, but they make the damping amount of the electromechanical interarea modes reduce. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eigenvalue%20analysis" title="Eigenvalue analysis">Eigenvalue analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microgrid" title=" microgrid"> microgrid</a>, <a href="https://publications.waset.org/abstracts/search?q=Hopf%20bifurcation" title=" Hopf bifurcation"> Hopf bifurcation</a>, <a href="https://publications.waset.org/abstracts/search?q=oscillatory%20stability" title=" oscillatory stability"> oscillatory stability</a> </p> <a href="https://publications.waset.org/abstracts/75318/the-effect-of-microgrid-on-power-system-oscillatory-stability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75318.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">291</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Different Tillage Possibilities for Second Crop in Green Bean Farming</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yilmaz%20Bayhan">Yilmaz Bayhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20G%C3%BCzel"> Emin Güzel</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Bar%C4%B1%C5%9F%20%C3%96zl%C3%BCoymak"> Ömer Barış Özlüoymak</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20%C4%B0nce"> Ahmet İnce</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdullah%20Sessiz"> Abdullah Sessiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, determining of reduced tillage techniques in green bean farming as a second crop after harvesting wheat was targeted. To this aim, four different soil tillage methods namely, heavy-duty disc harrow (HD), rotary tiller (ROT), heavy-duty disc harrow plus rotary tiller (HD+ROT) and no-tillage (NT) (seeding by direct drill) were examined. Experiments were arranged in a randomized block design with three replications. The highest green beans yields were obtained in HD+ROT and NT as 5,862.1 and 5,829.3 Mg/ha, respectively. The lowest green bean yield was found in HD as 3,076.7 Mg/ha. The highest fuel consumption was measured 30.60 L ha<sup>-1 </sup>for HD+ROT whereas the lowest value was found 7.50 L ha<sup>-1</sup> for NT. No tillage method gave the best results for fuel consumption and effective power requirement. It is concluded that no-tillage method can be used in second crop green bean in the Thrace Region due to economic and erosion conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20bean" title="green bean">green bean</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20tillage" title=" soil tillage"> soil tillage</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=vegetative" title=" vegetative"> vegetative</a> </p> <a href="https://publications.waset.org/abstracts/68586/different-tillage-possibilities-for-second-crop-in-green-bean-farming" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68586.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Pre-Beneficiation of Low Grade Diasporic Bauxite Ore by Reduction Roasting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koksal%20Y%C4%B1lmaz">Koksal Yılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Birol"> Burak Birol</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhlis%20Nezihi%20Saridede"> Muhlis Nezihi Saridede</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdogan%20Yigit"> Erdogan Yigit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A bauxite ore can be utilized in Bayer Process, if the mass ratio of Al2O3 to SiO2 is greater than 10.

A morphology transition from needle like structure to hexagonal plates, and then needle-like again has been observed as the DI-H2O was added continuously (0.0 wt% to 3.0wt%).

In this regard, for Turkey a data relay system is attempted to be defined exchanging low data rate information (i.e. TTC) for Earth-observing LEO satellites appointing commercial GEO communication satellites all over the world. First, justification of this attempt is given, demonstrating duration enhancements in the link. Discussion of preference of RF communication is, also, given instead of laser communication. Then, preferred communication GEOs – including TURKSAT4A already belonging to Turkey- are given, together with the coverage enhancements through STK simulations and the corresponding link budget. Also, a block diagram of the communication system is given on the LEO satellite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication" title="communication">communication</a>, <a href="https://publications.waset.org/abstracts/search?q=GEO%20satellite" title=" GEO satellite"> GEO satellite</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20relay%20system" title=" data relay system"> data relay system</a>, <a href="https://publications.waset.org/abstracts/search?q=coverage" title=" coverage"> coverage</a> </p> <a href="https://publications.waset.org/abstracts/45926/authorization-of-commercial-communication-satellite-grounds-for-promoting-turkish-data-relay-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45926.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">441</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Impact of Fly Ash-Based Geopolymer Modification on the High-Temperature Properties of Bitumen</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Burak%20Yigit%20Katanalp">Burak Yigit Katanalp</a>, <a href="https://publications.waset.org/abstracts/search?q=Murat%20Tastan"> Murat Tastan</a>, <a href="https://publications.waset.org/abstracts/search?q=Perviz%20Ahmedzade"> Perviz Ahmedzade</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%A7Igdem%20Canbay%20Turkyilmaz"> çIgdem Canbay Turkyilmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Turkyilmaz"> Emrah Turkyilmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study evaluated the mechanical and rheological performance of fly ash-based geopolymer at high temperatures. A series of laboratory tests were conducted on neat bitumen and three modified bitumen samples, which incorporated fly ash-based geopolymer at various percentages.

The dynamic shear rheometer and rotational viscometer were employed to determine high-temperature properties, while conventional tests such as penetration and softening point were used to evaluate the physical properties of bitumen. The short-term aging resistance of the samples was assessed using the rolling thin film oven.

In turn, the macro scale behavior of the soil mass results from particle level interactions which are affected by particle shape. Sphericity, roundness and smoothness characterize different scales associated to particle shape. New experimental data and data from previously published studies are gathered into two databases to explore the effects of particle shape on packing as well as small and large-strain properties of sandy soils. Data analysis shows that increased particle irregularity (angularity and/or eccentricity) leads to: an increase in emax and emin, a decrease in stiffness yet with increased sensitivity to the state of stress, an increase in compressibility under zero-lateral strain loading, and an increase in critical state friction angle φcs and intercept Γ with a weak effect on slope λ. Therefore, particle shape emerges as a significant soil index property that needs to be properly characterized and documented, particularly in clean sands and gravels. The systematic assessment of particle shape will lead to a better understanding of sand behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=angularity" title="angularity">angularity</a>, <a href="https://publications.waset.org/abstracts/search?q=eccentricity" title=" eccentricity"> eccentricity</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20%20particle" title=" shape particle"> shape particle</a>, <a href="https://publications.waset.org/abstracts/search?q=behavior%20of%20soil" title=" behavior of soil"> behavior of soil</a> </p> <a href="https://publications.waset.org/abstracts/17611/the-influence-of-the-form-of-grain-on-the-mechanical-behaviour-of-sand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17611.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Anatomical and Pathological Evaluation of Anomaly Cases Presented to the Department of Pathology at the Kafkas University Faculty of Veterinary Medicine, between 2017 and 2019</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BClseren%20K%C4%B1rba%C5%9F%20Do%C4%9Fan">Gülseren Kırbaş Doğan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Karakurt"> Emin Karakurt</a>, <a href="https://publications.waset.org/abstracts/search?q=Mushap%20Kuru"> Mushap Kuru</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilmi%20Nuho%C4%9Flu"> Hilmi Nuhoğlu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Developmental anomalies can be caused by defects in bone tissue, cartilage tissue, or primitive mesenchymal tissue. Genetic-, environmental-, teratogenic-, faulty breeding selection–, or feeding-related anomalies can be observed either locally or systemically. This study aimed to evaluate in detail the various anomalies in six calves according to pathological and anatomical investigations. Six calves were delivered to the Department of Pathology at the Kafkas University Faculty of Veterinary Medicine between 2017 and 2019. These calves comprised one with anencephaly, one with the diencephalic syndrome, one with Schistosoma reflexum, two with anasarca, and one with nasal and calvarium openings. After necropsy, samples were taken from the organs, foreseen, and routine pathological examinations were performed. Following these procedures, the calves were brought to the anatomy laboratory and anatomically examined. As a result, various anomalies in 6 calves were evaluated according to pathological and anatomical investigations. These findings are believed to contribute to the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=anomaly" title=" anomaly"> anomaly</a>, <a href="https://publications.waset.org/abstracts/search?q=calf" title=" calf"> calf</a>, <a href="https://publications.waset.org/abstracts/search?q=pathology" title=" pathology"> pathology</a> </p> <a href="https://publications.waset.org/abstracts/110508/anatomical-and-pathological-evaluation-of-anomaly-cases-presented-to-the-department-of-pathology-at-the-kafkas-university-faculty-of-veterinary-medicine-between-2017-and-2019" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110508.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">181</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Mechanical Properties and Microstructures of the Directional Solidified Zn-Al-Cu Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehmet%20Izzettin%20Yilmazer">Mehmet Izzettin Yilmazer</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Cadirli"> Emin Cadirli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zn-7wt.%Al-2.96wt.%Cu eutectic alloy was directionally solidified upwards with different temperature gradients (from 6.70 K/mm to 10.67 K/mm) at a constant growth rate (16.4 Km/s) and also different growth rate (from 8.3 micron/s to 166 micron/s) at a constant temperature gradient (10.67 K/mm) using a Bridgman–type growth apparatus.The values of eutectic spacing were measured from longitudinal and transverse sections of the samples.

A projectile with a mass of 1.25 gr and density of 11.3 gr/cm3 was fired at the joints with a velocity of about 280 m/s using a specially designed experimental set-up, and the impact was recorded via a high-speed camera. The SLJs were manufactured from 6061 aluminum adherend (AA6061) material and an adhesive film. The joints, which have an adherend thickness of 4 mm and overlap length of 15 mm, were subjected to up to 3 shots for the ballistic test, followed by quasi-static tensile testing. The impacted joints, then, were compared to the non-impacted and one-shot impacted ones, which was a subject of investigation carried out before. It was found that while the joints subjected to 2 shots mechanically deteriorated, those subjected to 3 shots experienced a complete failure at the end of the experiment. A numerical study was also conducted using an ABAQUS package program. While the adherends were modelled using the Johnson-Cook deformation parameters, an elastoplastic behavior of the adhesive was used as input data in the analyses. It seems the experimental results confirm the numerical ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ballistic%20tests" title="ballistic tests">ballistic tests</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesive%20joints" title=" adhesive joints"> adhesive joints</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20analysis" title=" numerical analysis"> numerical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=SLJ" title=" SLJ"> SLJ</a> </p> <a href="https://publications.waset.org/abstracts/180863/effects-of-repeated-high-loadings-on-the-performance-of-adhesively-bonded-single-lap-joints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/180863.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Numerical and Experimental Investigations of Cantilever Rectangular Plate Structure on Subsonic Flutter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mevl%C3%BCt%20Burak%20Dalm%C4%B1%C5%9F">Mevlüt Burak Dalmış</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Yaman"> Kemal Yaman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, flutter characteristics of cantilever rectangular plate structure under incompressible flow regime are investigated by comparing the results of commercial flutter analysis program ZAERO<sup>©</sup> with wind tunnel tests conducted in Ankara Wind Tunnel (ART).

In this paper, we present a novel method to analyze the similarity between the substructures of the imaged region and a hand drawn template, on hip radiographs to detect obturator foramen accurately with integrated usage of Marker-controlled Watershed segmentation and Zernike moment feature descriptor. Marker-controlled Watershed segmentation is applied to seperate obturator foramen from the background effectively. Zernike moment feature descriptor is used to provide matching between binary template image and the segmented binary image for obturator foramens for final extraction. The proposed method is tested on randomly selected 100 hip radiographs.

The term procyclicality refers here the cyclical behavior of banks that lead them to follow the same patterns as the real economy. In this study, leverage which demonstrate how a bank manage its debt, is chosen as bank specific variable to see the effect of changes in it over the economic cycle. The procyclical behavior of Turkish banking sector (commercial, participation, development-investment banks) is tried to explain with analyzing the relationship between leverage and asset growth. On the basis of theoretical explanations, eight different leverage ratios are utilized in eight different panel data models to demonstrate the procyclicality effect of Turkish banks leverage using monthly data covering the 2005-2014 period. It is tested whether there is an increasing (decreasing) trend in the leverage ratio of Turkish banks when there is an enlargement (contraction) in their balance sheet. The major finding of the study indicates that asset growth has a significant effect on all eight leverage ratios. In other words, the leverage of Turkish banks follow a cyclical pattern, which is in line with those of earlier literature. <p class="card-text"><strong>Keywords:</strong> <a
