on population assessments are essential for global ecosystem assessment because the temporal change of biomass in such a database reflects the status of global ecosystem properly. However, the available assessment data usually have limited sample sizes and the ratio of populations with low abundance of biomass (collapsed) to those with high abundance (non-collapsed) is highly imbalanced. To allow for the imbalance and uncertainty involved in the ecological data, we propose a binary regression model with mixed effects for inferring ecosystem status through an asymmetric logistic model. In the estimation equation, we observe that the weights for the non-collapsed populations are relatively reduced, which in turn puts more importance on the small number of observations of collapsed populations. Moreover, we extend the asymmetric logistic regression model using propensity score to allow for the sample biases observed in the labeled and unlabeled datasets. It robustified the estimation procedure and improved the model fitting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=double%20robust%20estimation" title="double robust estimation">double robust estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20binary%20data" title=" ecological binary data"> ecological binary data</a>, <a href="https://publications.waset.org/abstracts/search?q=mixed%20effect%20logistic%20regression%20model" title=" mixed effect logistic regression model"> mixed effect logistic regression model</a>, <a href="https://publications.waset.org/abstracts/search?q=propensity%20score" title=" propensity score"> propensity score</a> </p> <a href="https://publications.waset.org/abstracts/65277/robustified-asymmetric-logistic-regression-model-for-global-fish-stock-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65277.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">266</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">55</span> Slip Limit Prediction of High-Strength Bolt Joints Based on Local Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chang%20He">Chang He</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Tamura"> Hiroshi Tamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katsuchi"> Hiroshi Katsuchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaqi%20Wang"> Jiaqi Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the aim is to infer the slip limit (static friction limit) of contact interfaces in bolt friction joints by analyzing other bolt friction joints with the same contact surface but in a different shape.

When the ratio of the translation speed of a target to its vibration frequency is large, obtaining its frequency response in image intensities becomes difficult because one or no waves are observable at the same pixel. Our method can precisely localize moving objects with vibration by virtually translating multiple image sequences for pixel-level short-time Fourier transform to observe multiple waves at the same pixel.

How the optimal circuit can be signed was the most important issue to get the best performance. This architecture had succeeded for line based telephone system. The second generation was host centric network and Internet based on this architecture has very succeeded world widely. And Internet became as new social infrastructure. Currently the architecture of the network is based on the location of the information. This future network is called Information centric network (ICN). The information-centric network (ICN) has being researched by many projects and different architectures for implementation of ICN have been proposed. The goal of this study is to compare performances of those ICN architectures. In this paper, the authors propose general ICN model which can represent two typical ICN architectures and compare communication performances using request routing. Finally, simulation results are shown. Also, we assume that this network architecture should be adapt to energy on-demand routing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ICN" title="ICN">ICN</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20centric%20network" title=" information centric network"> information centric network</a>, <a href="https://publications.waset.org/abstracts/search?q=CCN" title=" CCN"> CCN</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a> </p> <a href="https://publications.waset.org/abstracts/68439/study-on-energy-performance-comparison-of-information-centric-network-based-on-difference-of-network-architecture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68439.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">337</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> Temperature-Based Detection of Initial Yielding Point in Loading of Tensile Specimens Made of Structural Steel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aqsa%20Jamil">Aqsa Jamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamura%20Hiroshi"> Tamura Hiroshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Katsuchi%20Hiroshi"> Katsuchi Hiroshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Jiaqi"> Wang Jiaqi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The yield point represents the upper limit of forces which can be applied to a specimen without causing any permanent deformation. After yielding, the behavior of the specimen suddenly changes, including the possibility of cracking or buckling. So, the accumulation of damage or type of fracture changes depending on this condition. As it is difficult to accurately detect yield points of the several stress concentration points in structural steel specimens, an effort has been made in this research work to develop a convenient technique using thermography (temperature-based detection) during tensile tests for the precise detection of yield point initiation. To verify the applicability of thermography camera, tests were conducted under different loading conditions and measuring the deformation by installing various strain gauges and monitoring the surface temperature with the help of a thermography camera. The yield point of specimens was estimated with the help of temperature dip, which occurs due to the thermoelastic effect during the plastic deformation. The scattering of the data has been checked by performing a repeatability analysis. The effects of temperature imperfection and light source have been checked by carrying out the tests at daytime as well as midnight and by calculating the signal to noise ratio (SNR) of the noised data from the infrared thermography camera, it can be concluded that the camera is independent of testing time and the presence of a visible light source. Furthermore, a fully coupled thermal-stress analysis has been performed by using Abaqus/Standard exact implementation technique to validate the temperature profiles obtained from the thermography camera and to check the feasibility of numerical simulation for the prediction of results extracted with the help of the thermographic technique. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=signal%20to%20noise%20ratio" title="signal to noise ratio">signal to noise ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=thermoelastic%20effect" title=" thermoelastic effect"> thermoelastic effect</a>, <a href="https://publications.waset.org/abstracts/search?q=thermography" title=" thermography"> thermography</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20point" title=" yield point"> yield point</a> </p> <a href="https://publications.waset.org/abstracts/151454/temperature-based-detection-of-initial-yielding-point-in-loading-of-tensile-specimens-made-of-structural-steel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151454.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">107</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">48</span> Measurement of Reverse Flow Generated at Cold Exit of Vortex Tube </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hazwan%20bin%20Yusof">Mohd Hazwan bin Yusof</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katanoda"> Hiroshi Katanoda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to clarify the structure of the cold flow discharged from the vortex tube (VT), the pressure of the cold flow was measured, and a simple flow visualization technique using a 0.75 mm-diameter needle and an oily paint is made to study the reverse flow at the cold exit.

The goal of our paper is to enrich visualization of tag clouds. A font distribution algorithm has been proposed to calculate a novel metric based on frequency and content, and to classify among classes from this metric based on power law distribution and percentages. The suggested algorithm has been validated and verified on the tag cloud of a real-world thesis portal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tag%20cloud" title="tag cloud">tag cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=font%20distribution%20algorithm" title=" font distribution algorithm"> font distribution algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency-based" title=" frequency-based"> frequency-based</a>, <a href="https://publications.waset.org/abstracts/search?q=content-based" title=" content-based"> content-based</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20law" title=" power law"> power law</a> </p> <a href="https://publications.waset.org/abstracts/8529/frequency-and-content-based-tag-cloud-font-distribution-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8529.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">505</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">46</span> Energy Separation Mechanism in Uni-Flow Vortex Tube Using Compressible Vortex Flow </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katanoda">Hiroshi Katanoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hazwan%20bin%20Yusof"> Mohd Hazwan bin Yusof</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A theoretical investigation from the viewpoint of gas-dynamics and thermodynamics was carried out, in order to clarify the energy separation mechanism in a viscous compressible vortex, as a primary flow element in a uni-flow vortex tube.

The questionnaire sheet used for this research was organized into the following categories: tension/tiredness, drowsiness while driving, and the nap situation during night-time work. The number of taxi drivers was 127 and the number of bus drivers was 40. Concerning the results of a comparison of nap hours of taxi and bus drivers, the taxi drivers’ nap hours are overwhelmingly shorter, and also the frequency of drivers who feel drowsiness is higher. The burden on bus drivers does not change because of the system of a two-driver rotation shift. In particular, the working environment of the taxi driver may lead to greater fatigue accumulation than the bus driver’s environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bus%20and%20taxi" title="bus and taxi">bus and taxi</a>, <a href="https://publications.waset.org/abstracts/search?q=drowsiness" title=" drowsiness"> drowsiness</a>, <a href="https://publications.waset.org/abstracts/search?q=fatigue" title=" fatigue"> fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=nap" title=" nap"> nap</a> </p> <a href="https://publications.waset.org/abstracts/32338/comparative-study-of-fatigue-and-drowsiness-in-the-night-time-passenger-transportation-industry-in-japan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32338.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">327</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> Ultraviolet Lasing from Vertically-Aligned ZnO Nanowall Array</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masahiro%20Takahashi">Masahiro Takahashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosuke%20Harada"> Kosuke Harada</a>, <a href="https://publications.waset.org/abstracts/search?q=Shihomi%20Nakao"> Shihomi Nakao</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitsuhiro%20Higashihata"> Mitsuhiro Higashihata</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Ikenoue"> Hiroshi Ikenoue</a>, <a href="https://publications.waset.org/abstracts/search?q=Daisuke%20Nakamura"> Daisuke Nakamura</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatsuo%20Okada"> Tatsuo Okada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Zinc oxide (ZnO) is one of the light emitting materials in ultraviolet (UV) region. In addition, ZnO nanostructures are also attracting increasing research interest as building blocks for UV optoelectronic applications. We have succeeded in synthesizing vertically-aligned ZnO nanostructures by laser interference patterning, which is catalyst-free and non-contact technique. In this study, vertically-aligned ZnO nanowall arrays were synthesized using two-beam interference. The maximum height and average thickness of the ZnO nanowalls were about 4.5 µm and 200 nm, respectively. UV lasing from a piece of the ZnO nanowall was obtained under the third harmonic of a Q-switched Nd:YAG laser excitation, and the estimated threshold power density for lasing was about 150 kW/cm2. Furthermore, UV lasing from the vertically-aligned ZnO nanowall was also achieved. The results indicate that ZnO nanowalls can be applied to random laser. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=zinc%20oxide" title="zinc oxide">zinc oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanowall" title=" nanowall"> nanowall</a>, <a href="https://publications.waset.org/abstracts/search?q=interference%20laser" title=" interference laser"> interference laser</a>, <a href="https://publications.waset.org/abstracts/search?q=UV%20lasing" title=" UV lasing"> UV lasing</a> </p> <a href="https://publications.waset.org/abstracts/23913/ultraviolet-lasing-from-vertically-aligned-zno-nanowall-array" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23913.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">504</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">42</span> Winged Test Rocket with Fully Autonomous Guidance and Control for Realizing Reusable Suborbital Vehicle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Koichi%20Yonemoto">Koichi Yonemoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Yamasaki"> Hiroshi Yamasaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Masatomo%20Ichige"> Masatomo Ichige</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuke%20Ura"> Yusuke Ura</a>, <a href="https://publications.waset.org/abstracts/search?q=Guna%20S.%20Gossamsetti"> Guna S.

However, in the IP network, the responsibility for management of multicast groups is distributed among network routers, which causes some limitations such as delays in processing group events, high bandwidth consumption and redundant tree calculation. Software Defined Networking (SDN) represented by OpenFlow presented as a solution for many problems, in SDN the control plane and data plane are separated by shifting the control and management to a remote centralized controller, and the routers are used as a forwarder only. In this paper we will proposed fast switching mechanism for solving the problem of link failure in multicast tree based on Tabu Search heuristic algorithm and modifying the functions of OpenFlow switch to fasts switch to the pack up sub tree rather than sending to the controller. In this work we will implement multicasting OpenFlow controller, this centralized controller is a core part in our multicasting approach, which is responsible for 1- constructing the multicast tree, 2- handling the multicast group events and multicast state maintenance. And finally modifying OpenFlow switch functions for fasts switch to pack up paths. Forwarders, forward the multicast packet based on multicast routing entries which were generated by the centralized controller. Tabu search will be used as heuristic algorithm for construction near optimum multicast tree and maintain multicast tree to still near optimum in case of join or leave any members from multicast group (group events). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multicast%20tree" title="multicast tree">multicast tree</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20define%20networks" title=" software define networks"> software define networks</a>, <a href="https://publications.waset.org/abstracts/search?q=tabu%20search" title=" tabu search"> tabu search</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenFlow" title=" OpenFlow"> OpenFlow</a> </p> <a href="https://publications.waset.org/abstracts/47773/fast-switching-mechanism-for-multicasting-failure-in-openflow-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47773.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">263</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> Characterization of Monoclonal Antibodies Specific for Synthetic Cannabinoids</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Nakayama">Hiroshi Nakayama</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuji%20Ito"> Yuji Ito</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Synthetic cannabinoids have attracted much public attention recently in Japan. 1-pentyl-3-(1-naphthoyl)-indole (JWH-018), 1-pentyl-2-methyl-3-(1-naphthoyl) indole (JWH-015), 1-(5-fluoropentyl)-3- (1-(2,2,3,3- tetramethylcyclopropyl)) indole (XLR-11) and 1-methyl-3- (1-admantyl) indole (JWH-018 adamantyl analog) are known as synthetic cannabinoids and are also considered dangerous illegal drugs in Japan. It has become necessary to develop sensitive and useful methods for detection of synthetic cannabinoids. We produced two monoclonal antibodies (MAb) against synthetic cannabinoids, named NT1 (IgG1) and NT2 (IgG1), using Hybridoma technology. The cross-reactivity of these produced MAbs was evaluated using a competitive enzyme-linked immunosorbent assay (ELISA). In the results, we found both of these antibodies recognize many kinds of synthetic cannabinoids analog. However, neither of these antibodies recognizes naphtoic acid, 1-methyl-indole and indole known as a raw material of synthetic cannabinoid. Thus, the MAbs produced in this study could be a useful tool for the detection of synthetic cannabinoids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ELISA" title="ELISA">ELISA</a>, <a href="https://publications.waset.org/abstracts/search?q=monoclonal%20antibody" title=" monoclonal antibody"> monoclonal antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=sensor" title=" sensor"> sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20cannabinoid" title=" synthetic cannabinoid"> synthetic cannabinoid</a> </p> <a href="https://publications.waset.org/abstracts/51072/characterization-of-monoclonal-antibodies-specific-for-synthetic-cannabinoids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51072.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">355</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">39</span> BECOME: Body Experience-Based Co-Operation between Juveniles through Mutually Excited Team Gameplay</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsugunosuke%20Sakai">Tsugunosuke Sakai</a>, <a href="https://publications.waset.org/abstracts/search?q=Haruya%20Tamaki"> Haruya Tamaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryuichi%20Yoshida"> Ryuichi Yoshida</a>, <a href="https://publications.waset.org/abstracts/search?q=Ryohei%20Egusa"> Ryohei Egusa</a>, <a href="https://publications.waset.org/abstracts/search?q=Etsuji%20Yamaguchi"> Etsuji Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shigenori%20Inagaki"> Shigenori Inagaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusako%20Kusunoki"> Fusako Kusunoki</a>, <a href="https://publications.waset.org/abstracts/search?q=Miki%20Namatame"> Miki Namatame</a>, <a href="https://publications.waset.org/abstracts/search?q=Masanori%20Sugimoto"> Masanori Sugimoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Mizoguchi"> Hiroshi Mizoguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We aim to develop a full-body interaction game that could let children cooperate and interact with other children in small groups.

These included shouting time, watching each other, and jumping in a constant rhythm as if they were skipping rope. In this manner, we observed the children playing the game while cooperating with each other.

The prefrontal blood flow distribution pattern when advanced second-language listeners listened to a second language (L2) was most similar to that when listening to their first language (L1) among the patterns of mean and standard deviation. In experiments with 25 healthy subjects, the maximum blood flow was localized to the left BA46 of advanced listeners. The blood flow presented is robust to baseline drift and stably localizes regional brain activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NIRS" title="NIRS">NIRS</a>, <a href="https://publications.waset.org/abstracts/search?q=oxy-hemoglobin" title=" oxy-hemoglobin"> oxy-hemoglobin</a>, <a href="https://publications.waset.org/abstracts/search?q=baseline%20drift" title=" baseline drift"> baseline drift</a>, <a href="https://publications.waset.org/abstracts/search?q=blood%20flow" title=" blood flow"> blood flow</a>, <a href="https://publications.waset.org/abstracts/search?q=working%20memory" title=" working memory"> working memory</a>, <a href="https://publications.waset.org/abstracts/search?q=BA46" title=" BA46"> BA46</a>, <a href="https://publications.waset.org/abstracts/search?q=first%20language" title=" first language"> first language</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20language" title=" second language"> second language</a> </p> <a href="https://publications.waset.org/abstracts/22459/a-novel-nris-index-to-evaluate-brain-activity-in-prefrontal-regions-while-listening-to-first-and-second-languages-for-long-time-periods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22459.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">559</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">36</span> Study on Planning of Smart GRID Using Landscape Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sunglim%20Lee">Sunglim Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Susumu%20Fujii"> Susumu Fujii</a>, <a href="https://publications.waset.org/abstracts/search?q=Koji%20Okamura"> Koji Okamura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Smart grid is a new approach for electric power grid that uses information and communications technology to control the electric power grid. Smart grid provides real-time control of the electric power grid, controlling the direction of power flow or time of the flow. Control devices are installed on the power lines of the electric power grid to implement smart grid. The number of the control devices should be determined, in relation with the area one control device covers and the cost associated with the control devices. One approach to determine the number of the control devices is to use the data on the surplus power generated by home solar generators. In current implementations, the surplus power is sent all the way to the power plant, which may cause power loss. To reduce the power loss, the surplus power may be sent to a control device and sent to where the power is needed from the control device. Under assumption that the control devices are installed on a lattice of equal size squares, our goal is to figure out the optimal spacing between the control devices, where the power sharing area (the area covered by one control device) is kept small to avoid power loss, and at the same time the power sharing area is big enough to have no surplus power wasted. To achieve this goal, a simulation using landscape ecology method is conducted on a sample area. First an aerial photograph of the land of interest is turned into a mosaic map where each area is colored according to the ratio of the amount of power production to the amount of power consumption in the area. The amount of power consumption is estimated according to the characteristics of the buildings in the area. The power production is calculated by the sum of the area of the roofs shown in the aerial photograph and assuming that solar panels are installed on all the roofs. The mosaic map is colored in three colors, each color representing producer, consumer, and neither. We started with a mosaic map with 100 m grid size, and the grid size is grown until there is no red grid. One control device is installed on each grid, so that the grid is the area which the control device covers. As the result of this simulation we got 350 m as the optimal spacing between the control devices that makes effective use of the surplus power for the sample area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=landscape%20ecology" title="landscape ecology">landscape ecology</a>, <a href="https://publications.waset.org/abstracts/search?q=IT" title=" IT"> IT</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20grid" title=" smart grid"> smart grid</a>, <a href="https://publications.waset.org/abstracts/search?q=aerial%20photograph" title=" aerial photograph"> aerial photograph</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/3371/study-on-planning-of-smart-grid-using-landscape-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3371.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">444</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">35</span> Rasch Analysis in the Development of 'Kohesif-Ques': An Instrument to Measure Social Cohesion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paramita%20Sekar%20Ayu">Paramita Sekar Ayu</a>, <a href="https://publications.waset.org/abstracts/search?q=Sunjaya%20Deni%20Kurniadi"> Sunjaya Deni Kurniadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yamazaki%20Chiho"> Yamazaki Chiho</a>, <a href="https://publications.waset.org/abstracts/search?q=Hilfi%20Lukman"> Hilfi Lukman</a>, <a href="https://publications.waset.org/abstracts/search?q=Koyama%20Hiroshi"> Koyama Hiroshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social cohesion, or closeness among members of society, is an important determinant of population health. A cohesive society is a crucial societal condition for a positive life evaluation and subjective wellbeing, and people living in a cohesive society are happier and more satisfied with life and achieve better health status. The objective of this study was to compose and validate a questionnaire for measuring social cohesion with Rasch analysis. We develop a set of 13 questions to measure 4 dimensions of social cohesion. Random samples of 166 Bandung citizens’ were selected to answer the questionnaire. To evaluate the questionnaire’s validity and reliability, Rasch analysis (a psychometric model for analyzing categorical data on questionnaire responses) was carried out using Winsteps version 3.75.0. Rasch analysis was performed on the response given to 13 items included in the questionnaire. The reliability coefficient, Cronbach’s alpha was 0.70, model RMSE 0.08, SD 0.54, separation 7.14, and reliability of 0.98. ‘Kohesif-Ques’ is a useful instrument to assess social cohesion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rasch%20analysis" title="rasch analysis">rasch analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=rasch%20model" title=" rasch model"> rasch model</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20cohesion" title=" social cohesion"> social cohesion</a>, <a href="https://publications.waset.org/abstracts/search?q=quesionnaire" title=" quesionnaire"> quesionnaire</a> </p> <a href="https://publications.waset.org/abstracts/97217/rasch-analysis-in-the-development-of-kohesif-ques-an-instrument-to-measure-social-cohesion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97217.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">177</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">34</span> Interaction between Unsteady Supersonic Jet and Vortex Rings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazumasa%20Kitazono">Kazumasa Kitazono</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Fukuoka"> Hiroshi Fukuoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nao%20Kuniyoshi"> Nao Kuniyoshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Minoru%20Yaga"> Minoru Yaga</a>, <a href="https://publications.waset.org/abstracts/search?q=Eri%20Ueno"> Eri Ueno</a>, <a href="https://publications.waset.org/abstracts/search?q=Naoaki%20Fukuda"> Naoaki Fukuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshio%20Takiya"> Toshio Takiya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The unsteady supersonic jet formed by a shock tube with a small high-pressure chamber was used as a simple alternative model for pulsed laser ablation. Understanding the vortex ring formed by the shock wave is crucial in clarifying the behavior of unsteady supersonic jet discharged from an elliptical cell. Therefore, this study investigated the behavior of vortex rings and a jet. The experiment and numerical calculation were conducted using the schlieren method and by solving the axisymmetric two-dimensional compressible Navier–Stokes equations, respectively. In both, the calculation and the experiment, laser ablation is conducted for a certain duration, followed by discharge through the exit. Moreover, a parametric study was performed to demonstrate the effect of pressure ratio on the interaction among vortex rings and the supersonic jet. The interaction between the supersonic jet and the vortex rings increased the velocity of the supersonic jet up to the magnitude of the velocity at the center of the vortex rings. The interaction between the vortex rings increased the velocity at the center of the vortex ring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=shock-wave" title=" shock-wave"> shock-wave</a>, <a href="https://publications.waset.org/abstracts/search?q=unsteady%20jet" title=" unsteady jet"> unsteady jet</a>, <a href="https://publications.waset.org/abstracts/search?q=vortex%20ring" title=" vortex ring"> vortex ring</a> </p> <a href="https://publications.waset.org/abstracts/50911/interaction-between-unsteady-supersonic-jet-and-vortex-rings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50911.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">470</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">33</span> An Experimental Study on Intellectual Concentration Influenced by Indoor Airflow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyoko%20Ito">Kyoko Ito</a>, <a href="https://publications.waset.org/abstracts/search?q=Shinya%20Furuta"> Shinya Furuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Daisuke%20Kamihigashi"> Daisuke Kamihigashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimi%20Ueda"> Kimi Ueda</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirotake%20Ishii"> Hirotake Ishii</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Shimoda"> Hiroshi Shimoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Fumiaki%20Obayashi"> Fumiaki Obayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazuhiro%20Taniguchi"> Kazuhiro Taniguchi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to improve intellectual concentration, few studies have verified the effect of indoor airflow among the thermal environment conditions, and the differences of the season in effects have not been studied.

In the previous study, an effective airflow in summer was proposed and the improvement of intellectual concentration by evaluation experiment was confirmed. Therefore, an airflow profile in winter was proposed with reference to the airflow profile in summer. The airflows are a combination of a simulative airflow and mild airflow. An experiment has been conducted to investigate the influence of a room airflow in winter on intellectual concentration. As a result of comparison with no airflow condition, no significant difference was found.

In this paper, we construct mathematical model of the unconstrained bed monitoring system, and we apply the unconstrained bed sensing method to the system for detecting scratching motion. The proposed sensors are placed under the three bed feet. When the person is lying on the bed, the output signals from the sensors are proportional to the magnitude of the vibration due to the scratching motion. Hence, we could detect the subject’s scratching motion from the output signals from ceramic sensors. We evaluated two scratching motions using the proposed system in the validity experiment as follows: First experiment is the subject’s scratching the right side cheek with his right hand, and; second experiment is the subject’s scratching the shin with another foot. As the results of the experiment, we recognized the scratching signals that enable the determination when the scratching occurred. Furthermore, the difference among the amplitudes of the output signals enabled us to estimate where the subject scratched. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconstrained%20bed%20sensing%20method" title="unconstrained bed sensing method">unconstrained bed sensing method</a>, <a href="https://publications.waset.org/abstracts/search?q=scratching" title=" scratching"> scratching</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20movement" title=" body movement"> body movement</a>, <a href="https://publications.waset.org/abstracts/search?q=itchy" title=" itchy"> itchy</a>, <a href="https://publications.waset.org/abstracts/search?q=piezoceramics" title=" piezoceramics"> piezoceramics</a> </p> <a href="https://publications.waset.org/abstracts/1382/development-of-scratching-monitoring-system-based-on-mathematical-model-of-unconstrained-bed-sensing-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1382.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">411</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">31</span> Health-Related QOL of Motorists with Spinal Cord Injury in Japan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroaki%20Hirose">Hiroaki Hirose</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Ikeda"> Hiroshi Ikeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Isao%20Takeda"> Isao Takeda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Japanese version of the SF-36 has been employed to assess individuals’ health-related QOL (HRQOL).

A total of 100 motorists with a spinal cord injury participated in this study. Participants’ HRQOL was evaluated using the Japanese version of the SF-36 (second edition). The score for each subscale was standardized based on data on the Japanese population.

However, it is difficult to secure a sufficient base area for shafts in an urban area because many streets are narrow with a complex layout. As a result, construction in such urban areas is generally very demanding. In urban areas, there is a strong requirement for a safe, reliable and economical construction method that does not disturb the public’s daily life and urban activities. With this in mind, we developed a new construction method called the 'shield switching type micro-tunneling method' which integrates the micro-tunneling method and shield method. In this method, pipeline is constructed first for sections that are gently curved or straight using the economical micro-tunneling method, and then the method is switched to the shield method for sections with a sharp curve or a series of curves without establishing an intermediate shaft.

The Mg, P and S distribution in µ-XRF mapping images correspond to the dark and light bands along the annual growth rings observed in microscopic images of the coral skeleton. The µ-XRF mapping data showed a positive correlation (r = 0.6) between P and S distribution in the coral skeleton. A contrasting distribution pattern of S and Mg along the axial skeleton of P. japonicum indicates a weak negative correlation (r = -0.2) between these two trace elements. The distribution pattern of S, P and Mg reveals linkage between their distributions and the formation of dark/light bands along the annual growth rings in the axial skeleton of P. japonicum.

Subsequently, we synchronized LiDAR distance measurements that were corrected by using attitude information from gyroscope with PPK GPS coordinates for generation of precision topographic maps, which could be further utilized for such applications like precise land leveling and drainage management. The results indicated that LiDAR distance measurements and PPK GPS altitude reached good accuracy of less than 0.015 m. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=land%20survey" title="land survey">land survey</a>, <a href="https://publications.waset.org/abstracts/search?q=light%20detection%20and%20ranging" title=" light detection and ranging"> light detection and ranging</a>, <a href="https://publications.waset.org/abstracts/search?q=post%20processing%20kinematic%20global%20positioning%20system" title=" post processing kinematic global positioning system"> post processing kinematic global positioning system</a>, <a href="https://publications.waset.org/abstracts/search?q=precision%20agriculture" title=" precision agriculture"> precision agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=topographic%20map" title=" topographic map"> topographic map</a>, <a href="https://publications.waset.org/abstracts/search?q=unmanned%20aerial%20vehicle" title=" unmanned aerial vehicle"> unmanned aerial vehicle</a> </p> <a href="https://publications.waset.org/abstracts/80276/topographic-mapping-of-farmland-by-integration-of-multiple-sensors-on-board-low-altitude-unmanned-aerial-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80276.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">236</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">27</span> Comparison of Allelopathic Activity of Some Edible Mushroom and Wild Mushroom in Japan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Asma%20Osivand">Asma Osivand</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Mardani"> Hossein Mardani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Araya"> Hiroshi Araya</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshiharu%20Fujii"> Yoshiharu Fujii</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wild mushrooms have always been considered as valuable source of bioactive compounds, while edible mushrooms have been known for their importance as food source. However, their interaction with plants through chemicals that could lead to find new biochemical have not been well undertaken. A special bioassay method (Sandwich method) was applied to compare eight common edible mushrooms (Pleurotus eryngii, Pleurotus citrinopileatus, Pleurotus ostreatus, Lentinula edodes, Grifola frondosa, Flammulina velutipes, Hypsizygus tessellatus and Pholiota namako) with some wild species (Ganoderma appelanatum, Amanita pantherina, Artomyces pyxidatus, Morchella conica, Tricholosporum porphyrophyllum, Trametes hirsuta) for their phytotoxicity against lettuce. Among all tested edible mushrooms, application of 5 mg of P. ostreatus showed stronger allelopathic activity by inhibiting the growth of radicle and hypocotyl of lettuce by 84% and 63% respectively. Moreover, same amount of T. porphyrophyllum exerted 77% and 67% growth inhibition on radicle and hypocotyl of lettuce. In general, biochemicals contributed in tested mushrooms could be the main cause for their inhibitory activity and could lead to find new allelochemicals. <p
