</p> <p class="card-text"><strong>Abstract:</strong></p> Self-assembly of a series of ZnX2 (X- = Cl-, Br-, and I-) with 2,3-bis(4’-nicotinamidephenoxy)naphthalene (L) as a new bidentate pyridyl-donor ligand yields systematic metallacyclodimeric unit, [ZnX2L]2. The supramolecule constitutes a characteristically stacked forming both 1D suprachannels and cages. Weak C-H⋯π and inter-digitated π⋯π interactions are main driving forces in the formation of both suprachannels and cages. The slightly different features between the suprachannel and cage have been investigated by 1H NMR and TG analysis, which solvent quantitatively exchange within only suprachannels. Photo-unstable CH2I2 molecules are stabilized via capturing within suprachannels, which is monitored by UV-Vis spectroscopy. Furthermore, the photoluminescence intensity, from the chromophore naphthyl moiety of [ZnCl2L]2, gradually decreases with the addition of CH2I2. And washing off the CH2I2 by dichloromethane returned the PL intensity back to its approximately original signal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metallacyclodimer" title="metallacyclodimer">metallacyclodimer</a>, <a href="https://publications.waset.org/abstracts/search?q=suprachannel" title=" suprachannel"> suprachannel</a>, <a href="https://publications.waset.org/abstracts/search?q=%CF%80%E2%8B%AF%CF%80%20interaction" title=" π⋯π interaction"> π⋯π interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20recognition" title=" molecular recognition"> molecular recognition</a> </p> <a href="https://publications.waset.org/abstracts/85931/metallacyclodimeric-array-containing-both-suprachannels-and-cages-selective-reservoir-and-recognition-of-diiodomethane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85931.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">322</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">283</span> Tolerating Input Faults in Asynchronous Sequential Machines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jung-Min%20Yang">Jung-Min Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A method of tolerating input faults for input/state asynchronous sequential machines is proposed. A corrective controller is placed in front of the considered asynchronous machine to realize model matching with a reference model. The value of the external input transmitted to the closed-loop system may change by fault. We address the existence condition for the controller that can counteract adverse effects of any input fault while maintaining the objective of model matching. A design procedure for constructing the controller is outlined. The proposed reachability condition for the controller design is validated in an illustrative example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asynchronous%20sequential%20machines" title="asynchronous sequential machines">asynchronous sequential machines</a>, <a href="https://publications.waset.org/abstracts/search?q=corrective%20control" title=" corrective control"> corrective control</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20tolerance" title=" fault tolerance"> fault tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20faults" title=" input faults"> input faults</a>, <a href="https://publications.waset.org/abstracts/search?q=model%20matching" title=" model matching"> model matching</a> </p> <a href="https://publications.waset.org/abstracts/41919/tolerating-input-faults-in-asynchronous-sequential-machines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41919.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">424</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">282</span> Comparison of Wind Fragility for Window System in the Simplified 10 and 15-Story Building Considering Exposure Category </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Viriyavudh%20Sim">Viriyavudh Sim</a>, <a href="https://publications.waset.org/abstracts/search?q=WooYoung%20Jung"> WooYoung Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Window system in high rise building is occasionally subjected to an excessive wind intensity, particularly during typhoon.

The probability of failure for individual window was determined with Monte Carlo Simulation method. Then, lognormal cumulative distribution function was used to represent the fragility. The results showed that windows located on the edge of leeward wall were more susceptible to wind load and the probability of failure for each window panel increased at higher floors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title="wind fragility">wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=window%20system" title=" window system"> window system</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20rise%20building" title=" high rise building"> high rise building</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20disaster" title=" wind disaster"> wind disaster</a> </p> <a href="https://publications.waset.org/abstracts/61408/comparison-of-wind-fragility-for-window-system-in-the-simplified-10-and-15-story-building-considering-exposure-category" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61408.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">314</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">281</span> The Flexural Strength of Fiber-Reinforced Polymer Cement Mortars Using UM Resin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Min%20Ho%20Kwon">Min Ho Kwon</a>, <a href="https://publications.waset.org/abstracts/search?q=Woo%20Young%20Jung"> Woo Young Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun%20Su%20Seo"> Hyun Su Seo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A Polymer Cement Mortar (PCM) has been widely used as the material of repair and restoration work for concrete structure; however a PCM usually induces an environmental pollutant. Therefore, there is a need to develop PCM which is less impact to environments. Usually, UM resin is known to be harmless to the environment. Accordingly, in this paper, the properties of the PCM using UM resin were studied. The general cement mortar and UM resin was mixed in the specified ratio. A certain percentage of PVA fibers, steel fibers and mixed fibers (PVA fiber and steel fiber) were added to enhance the flexural strength. The flexural tests were performed in order to investigate the flexural strength of each PCM. Experimental results showed that the strength of proposed PCM using UM resin is improved when they are compared with general cement mortar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymer%20cement%20mortar" title="polymer cement mortar">polymer cement mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=UM%20resin" title=" UM resin"> UM resin</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=PVA%20fiber" title=" PVA fiber"> PVA fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20fiber" title=" steel fiber"> steel fiber</a> </p> <a href="https://publications.waset.org/abstracts/3903/the-flexural-strength-of-fiber-reinforced-polymer-cement-mortars-using-um-resin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3903.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">343</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">280</span> Big Data Analysis with RHadoop</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ji%20Eun%20Shin">Ji Eun Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Ho%20Jung"> Byung Ho Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Dong%20Hoon%20Lim"> Dong Hoon Lim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is almost impossible to store or analyze big data increasing exponentially with traditional technologies. Hadoop is a new technology to make that possible. R programming language is by far the most popular statistical tool for big data analysis based on distributed processing with Hadoop technology. With RHadoop that integrates R and Hadoop environment, we implemented parallel multiple regression analysis with different sizes of actual data. Experimental results showed our RHadoop system was much faster as the number of data nodes increases. We also compared the performance of our RHadoop with lm function and big lm packages available on big memory. The results showed that our RHadoop was faster than other packages owing to paralleling processing with increasing the number of map tasks as the size of data increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20data" title="big data">big data</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadoop" title=" Hadoop"> Hadoop</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20regression%20analysis" title=" parallel regression analysis"> parallel regression analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=R" title=" R"> R</a>, <a href="https://publications.waset.org/abstracts/search?q=RHadoop" title=" RHadoop "> RHadoop </a> </p> <a href="https://publications.waset.org/abstracts/36106/big-data-analysis-with-rhadoop" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36106.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">437</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">279</span> Remanufacturing and Integrity Assessment of a 27-Year-Old 25kV Gas Insulated Switchgear: A Comprehensive Study on Dismantling, Inspection, and Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yechan%20Kim">Yechan Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Bonhyuk%20Ku"> Bonhyuk Ku</a>, <a href="https://publications.waset.org/abstracts/search?q=Minkyung%20Jung"> Minkyung Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoungku%20Kang"> Hyoungku Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presents the remanufacturing of a 25kV gas insulated switchgear (GIS) that operated indoors for 27 years before being decommissioned due to aging.

In this paper, wind fragility of window glass in residential apartment was determined to compare the difference between two window configuration models. Monte Carlo Simulation method had been used to derive damage data and analytical fragilities were constructed. Fragility of window system showed that window located in leeward wall had higher probability of failure, especially those close to the edge of structure. Between the two window models, Model 2 had higher probability of failure, this was due to the number of panel in this configuration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20fragility" title="wind fragility">wind fragility</a>, <a href="https://publications.waset.org/abstracts/search?q=glass%20window" title=" glass window"> glass window</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20rise%20building" title=" high rise building"> high rise building</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20disaster" title=" wind disaster"> wind disaster</a> </p> <a href="https://publications.waset.org/abstracts/61409/wind-fragility-of-window-glass-in-10-story-apartment-with-two-different-window-models" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61409.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">257</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">276</span> A Pedagogical Study of Computational Design in a Simulated Building Information Modeling-Cloud Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaehwan%20Jung">Jaehwan Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung-Ah%20Kim"> Sung-Ah Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Building Information Modeling (BIM) provides project stakeholders with various information about property and geometry of entire component as a 3D object-based parametric building model.

Recently, three-dimensional culture of astrocytes were actively applied to understand in vivo astrocyte works. Electrospun nanofibers are attractive for 3D cell culture system because they have a high surface to volume ratio and porous structure, and have already been used for 3D astrocyte cultures. In this research, the stiffness of cellulose acetate (CA) nanofiber was controlled by heat treatment. As stiffness increased, astrocyte cell viability and adhesion increased. Reactivity of astrocyte was also upregulated in stiffer CA nanofiber in terms of GFAP, an intermediate filament protein.

To increase the safety of this type of structure, a thorough analysis for displacement and bearing stress was performed for an extreme condition where a full cycle swing occurs. Different masses, ranging from 40 kg to 220 kg, and velocities were applied on the swing. Then, based on the solution of differential dynamics equation, swing velocity response to harmonic force was obtained. Moreover, the resistance capacity was estimated based on ACI steel structure design guide. Subsequently, numerical analysis was performed in ABAQUS to obtain the stress on each frame of the swing. Finally, the analysis shows that the expansion of swing structure frame section was required for mass bigger than 150kg. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swing%20structure" title="swing structure">swing structure</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement" title=" displacement"> displacement</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20stress" title=" bearing stress"> bearing stress</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20loads%20response" title=" dynamic loads response"> dynamic loads response</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a> </p> <a href="https://publications.waset.org/abstracts/88558/dynamics-analyses-of-swing-structure-subject-to-rotational-forces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88558.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">378</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">268</span> Analysis of the Recovery of Burnility Index and Reduction of CO2 for Cement Manufacturing Utilizing Waste Cementitious Powder as Alternative Raw Material of Limestone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kwon%20Eunhee">Kwon Eunhee</a>, <a href="https://publications.waset.org/abstracts/search?q=Park%20Dongcheon"> Park Dongcheon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jung%20Jaemin"> Jung Jaemin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In countries around the world, environmental regulations are being strengthened, and Korea is no exception to this trend, which means that environment pollution and the environmental load have recently become a significant issue.

In this research, the PET-based conductive fiber was prepared by silver conductive ink continuous coating. The conductive fiber showed low fiber resistance (10-¹~10Ω/cm), and the conductive behavior still had good performance (fiber resistance:10-¹~10Ω/cm， percentage of fiber resistance change:<60%) after the water wash durability test (AATCC-135， 30 times). This research provides a better solution to resolve the issues of resistance increase after the water wash process due to the damage to the conductive fiber structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PET" title="PET">PET</a>, <a href="https://publications.waset.org/abstracts/search?q=conductive%20fiber" title=" conductive fiber"> conductive fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=e-textiles" title=" e-textiles"> e-textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=wearable%20devices" title=" wearable devices"> wearable devices</a> </p> <a href="https://publications.waset.org/abstracts/166142/characteristics-of-pet-based-conductive-fiber" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166142.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">101</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">264</span> A Wireless Sensor Network Protocol for a Car Parking Space Monitoring System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jung-Ho%20Moon">Jung-Ho Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Myung-Gon%20Yoon"> Myung-Gon Yoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a wireless sensor network protocol for a car parking monitoring system. A wireless sensor network for the purpose is composed of multiple sensor nodes, a sink node, a gateway, and a server. Each of the sensor nodes is equipped with a 3-axis AMR sensor and deployed in the center of a parking space. The sensor node reads its sensor values periodically and transmits the data to the sink node if the current and immediate past sensor values show a difference exceeding a threshold value. The operations of the sink and sensor nodes are described in detail along with flow diagrams. The protocol allows a low-duty cycle operation of the sensor nodes and a flexible adjustment of the threshold value used by the sensor nodes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=car%20parking%20monitoring" title="car parking monitoring">car parking monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor%20node" title=" sensor node"> sensor node</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20network" title=" wireless sensor network"> wireless sensor network</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20protocol" title=" network protocol"> network protocol</a> </p> <a href="https://publications.waset.org/abstracts/11153/a-wireless-sensor-network-protocol-for-a-car-parking-space-monitoring-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11153.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">538</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">263</span> A Set of Microsatellite Markers for Population Genetics of Copper-Winged Bat (Myotis rufoniger) Using Saliva DNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junghwa%20An">Junghwa An</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungkyoung%20Choi"> Sungkyoung Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Eun%20Ye"> Eun Ye</a>, <a href="https://publications.waset.org/abstracts/search?q=San%20Hoon%20Han"> San Hoon Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Gun%20Choi"> Young-Gun Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chul%20Oun%20Jung"> Chul Oun Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The copper-winged bat (Myotis rufoniger) is the widely distributed medium body-sized bat in Asia, including Korea. This bat population has been decreasing because of habitat loss. This study reported the isolation and characterization of ten polymorphic microsatellite loci in endangered M. rufoniger. To do genetic studies, we use saliva DNA of bats during winter sleep period. The number of alleles per locus ranged from 2 to 9, and the observed and expected heterozygosities ranged from 0.063 to 0.750 and from 0.063 to 0.865, respectively. The average polymorphic information content (PIC) value of these markers was 0.37. Two loci of M. rufoniger showed departure from Hardy-Weinberg equilibrium(HWE). This demonstrated that the ten microsatellite loci can be used as genetic markers for further investigation of the copper-winged bat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=copper-winged%20bat" title="copper-winged bat">copper-winged bat</a>, <a href="https://publications.waset.org/abstracts/search?q=microsatellite" title=" microsatellite"> microsatellite</a>, <a href="https://publications.waset.org/abstracts/search?q=population%20genetics" title=" population genetics"> population genetics</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Korea" title=" South Korea"> South Korea</a> </p> <a href="https://publications.waset.org/abstracts/46642/a-set-of-microsatellite-markers-for-population-genetics-of-copper-winged-bat-myotis-rufoniger-using-saliva-dna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46642.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">262</span> The Vision Baed Parallel Robot Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20Lim">Sun Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyun%20Jung"> Kyun Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we describe the control strategy of high speed parallel robot system with EtherCAT network.

Additionally, the analysis of seismic fragility was based on Monte Carlo Simulation method combined with a 2D nonlinear finite element in ABAQUS platform with the consideration of deterioration of concrete. Finally, the comparison of seismic fragility of model pre- and post-deterioration was made to study the performance of weir.

In this study, with respect to the stress reduction that occurs over time, we carried out the theoretical review of the main cause based on the field measurements. As a result, the main cause of reduction in the cable-band bolt axial force was confirmed by the plastic deformation of the zinc plating layer used in the main cable wire, and thus, the theoretical process was established for the practical use in the field. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cable-band%20Bolts" title="cable-band Bolts">cable-band Bolts</a>, <a href="https://publications.waset.org/abstracts/search?q=field%20test" title=" field test"> field test</a>, <a href="https://publications.waset.org/abstracts/search?q=maintenance" title=" maintenance"> maintenance</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20reduction" title=" stress reduction"> stress reduction</a> </p> <a href="https://publications.waset.org/abstracts/36196/a-case-study-on-tension-drop-of-cable-band-bolts-in-suspension-bridge" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36196.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">332</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">258</span> Thermal Fatigue Behavior of Austenitic Stainless Steels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jung-Ho%20Moon">Jung-Ho Moon</a>, <a href="https://publications.waset.org/abstracts/search?q=Tae%20Kwon%20Ha"> Tae Kwon Ha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Continually increasing working temperature and growing need for greater efficiency and reliability of automotive exhaust require systematic investigation into the thermal fatigue properties especially of high temperature stainless steels.

This paper addresses corrective control for asynchronous machines with switching capability. The considered asynchronous machine consists of a set of different submachines and switches to each machine according to a constant switching sequence. The control goal is to design a corrective controller such that the closed-loop system can match the behavior of a reference model. The reachability of the switched asynchronous machine is described by a logic calculation of the reachability of submachines. The design procedure of the proposed corrective controller is outlined, and the applicability of the proposed scheme is validated in an example. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=switched%20asynchronous%20sequential%20machines" title="switched asynchronous sequential machines">switched asynchronous sequential machines</a>, <a href="https://publications.waset.org/abstracts/search?q=corrective%20control" title=" corrective control"> corrective control</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20feedback" title=" state feedback"> state feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=switching%20sequences" title=" switching sequences"> switching sequences</a> </p> <a href="https://publications.waset.org/abstracts/14853/on-control-of-asynchronous-sequential-machines-with-switching-capability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14853.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">457</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">255</span> Stress Variation of Underground Building Structure during Top-Down Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soo-yeon%20Seo">Soo-yeon Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Seol-ki%20Kim"> Seol-ki Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Su-jin%20Jung"> Su-jin Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the construction of a building, it is necessary to minimize construction period and secure enough work space for stacking of materials during the construction especially in city area.
