The passengers are subjected to queues and delays during the check-in process. These delays and queues are due to constraints in the capacity of service facilities. In this project, the airport terminal is decomposed into several check-in areas. The airport check-in scheduling problem requires both a deterministic (integer programming) and stochastic (simulation) approach. Integer programming formulations are provided to minimize the total number of counters in each check-in area under the realistic constraint that counters for one and the same flight should be adjacent and the desired number of counters remaining in each area should be fixed during check-in operations. By using simulation, the airport system can be modeled to study the effects of various parameters such as number of passengers on a flight and check-in counter opening and closing time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport%20terminal" title="airport terminal">airport terminal</a>, <a href="https://publications.waset.org/abstracts/search?q=integer%20programming" title=" integer programming"> integer programming</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/14259/airport-check-in-optimization-by-ip-and-simulation-in-combination" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14259.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">389</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">2401</span> Numerical Simulation and Experimental Validation of the Hydraulic L-Shaped Check Ball Behavior</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinji%20Kajiwara">Shinji Kajiwara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The spring-driven ball-type check valve is one of the most important components of hydraulic systems: it controls the position of the ball and prevents backward flow. To simplify the structure, the spring must be eliminated, and to accomplish this, the flow pattern and the behavior of the check ball in L-shaped pipe must be determined. In this paper, we present a full-scale model of a check ball made of acrylic resin, and we determine the relationship between the initial position of the ball, the position and diameter of the inflow port. The check flow rate increases in a standard center inflow model, and it is possible to greatly decrease the check-flow rate by shifting the inflow from the center. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulics" title="hydraulics">hydraulics</a>, <a href="https://publications.waset.org/abstracts/search?q=pipe%20flow" title=" pipe flow"> pipe flow</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20visualization" title=" flow visualization"> flow visualization</a>, <a href="https://publications.waset.org/abstracts/search?q=check%20ball" title=" check ball"> check ball</a>, <a href="https://publications.waset.org/abstracts/search?q=L-shaped%20pipe" title=" L-shaped pipe "> L-shaped pipe </a> </p> <a href="https://publications.waset.org/abstracts/24526/numerical-simulation-and-experimental-validation-of-the-hydraulic-l-shaped-check-ball-behavior" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24526.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">300</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">2400</span> Microstructure and SEM Analysis of Joints Fabricated by FSW of Aluminum Alloys 5083 and 6063</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaskirat%20Singh">Jaskirat Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Roshan%20Lal%20Virdi"> Roshan Lal Virdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khushdeep%20Goyal"> Khushdeep Goyal </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to perform a microstructural analysis of Friction Stir Welded joints of aluminum alloys 6063 and 5083, also to check the properties of the weld zone by SEM analysis.

In the world, all countries attach great importance to the coastal zone management and the coastal zone economy. In China, the government has developed a number of related coastal management policies and institutional, such as marine functional zoning, main function zoning, integrated coastal zone management, to ensure the sustainable utilization of the coastal zone and promote the development of coastal economic. However, in practice, the effect is not satisfactory. This paper analyses the coastal areas of coastal zone management on coastal economic growth contribution based on coastal areas economic development data with the 2007-2015 in China, which uses the method of the evaluation index system of coastal zone management institutional efficiency. The results show that the coastal zone management institutional objectives are not clear, and the institutional has high repeatability. At the same time, over management of coastal zone leads to low economic efficiency because the government management boundary is blurred. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=institutional%20overlap" title="institutional overlap">institutional overlap</a>, <a href="https://publications.waset.org/abstracts/search?q=over%20management" title=" over management"> over management</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20zone%20management" title=" coastal zone management"> coastal zone management</a>, <a href="https://publications.waset.org/abstracts/search?q=coastal%20zone%20economy" title=" coastal zone economy"> coastal zone economy</a> </p> <a href="https://publications.waset.org/abstracts/74771/institutional-superposition-over-management-and-coastal-economic-development-coastal-areas-in-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74771.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">393</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">2397</span> The Antecedents of Facebook Check in Adoption Intention: The Perspective of Social Influence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hsiu-Hua%20Cheng">Hsiu-Hua Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, the competition between websites becomes intense.

In this work, we suggest a modified or L2-adjusted check loss which rounds the sharp corner in the middle of check loss. It has a large effect of guarding against over fitted model in some extent. Through various simulation settings of linear and non-linear regressions, the improvement of check loss by L2 adjustment is empirically examined.

Over twenty years of peer-reviewed research demonstrates the powerful effects of this Positive Behavioral Interventions and Supports (PBIS) practice when implemented with fidelity. However, literature to date has not explicitly connected this intervention with Positive Psychology. Aims This session will illustrate the powerful role Positive Psychology and core elements of PERMA play in the worldwide success of this intervention and how more explicitly aligning Positive Behavioral Interventions and Supports (PBIS) practices with Positive Psychology might remove common barriers to current implementation. Method Students receiving the Check-In, Check-Out intervention experience a warm, positive greeting from a caring adult (CICO Coach) before entering their first class of the day. Teachers then provide high frequency positive feedback to the students at the end of each time block, or segment, of the day. An “optimistic close” to the day is then provided by the same CICO Coach at the end of the school day via the “check-out” process, where students assess the day’s accomplishments and goal-set for the next day. Results CICO clearly aligns with the Positive Psychology core elements of PERMA (Positive Emotion, Engagement, Relationships, Meaning and Accomplishments) and could be further strengthened through explicit integration. Conclusion The already powerful impact and reach of the Check-In, Check-Out intervention can be further enhanced and expanded through greater alignment with Positive Psychology elements and practices. Initiating this important alignment with CICO also offers promise for further integration of Positive Psychology and Positive Behavioral Interventions and Supports. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=positive%20pscyhology" title="positive pscyhology">positive pscyhology</a>, <a href="https://publications.waset.org/abstracts/search?q=check-In%20check-out" title=" check-In check-out"> check-In check-out</a>, <a href="https://publications.waset.org/abstracts/search?q=schools" title=" schools"> schools</a>, <a href="https://publications.waset.org/abstracts/search?q=alignment" title=" alignment"> alignment</a> </p> <a href="https://publications.waset.org/abstracts/171764/leveraging-positive-psychology-practices-to-elevate-the-impact-of-check-in-check-out-cico-in-schools" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171764.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">66</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">2392</span> Predicting Medical Check-Up Patient Re-Coming Using Sequential Pattern Mining and Association Rules</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rizka%20Aisha%20Rahmi%20Hariadi">Rizka Aisha Rahmi Hariadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20Ou-Yang"> Chao Ou-Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Han-Cheng%20Wang"> Han-Cheng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesri%20Govindaraju"> Rajesri Govindaraju</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As the increasing of medical check-up popularity, there are a huge number of medical check-up data stored in database and have not been useful. These data actually can be very useful for future strategic planning if we mine it correctly. In other side, a lot of patients come with unpredictable coming and also limited available facilities make medical check-up service offered by hospital not maximal. To solve that problem, this study used those medical check-up data to predict patient re-coming. Sequential pattern mining (SPM) and association rules method were chosen because these methods are suitable for predicting patient re-coming using sequential data. First, based on patient personal information the data was grouped into … groups then discriminant analysis was done to check significant of the grouping. Second, for each group some frequent patterns were generated using SPM method. Third, based on frequent patterns of each group, pairs of variable can be extracted using association rules to get general pattern of re-coming patient. Last, discussion and conclusion was done to give some implications of the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=patient%20re-coming" title="patient re-coming">patient re-coming</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20check-up" title=" medical check-up"> medical check-up</a>, <a href="https://publications.waset.org/abstracts/search?q=health%20examination" title=" health examination"> health examination</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=sequential%20pattern%20mining" title=" sequential pattern mining"> sequential pattern mining</a>, <a href="https://publications.waset.org/abstracts/search?q=association%20rules" title=" association rules"> association rules</a>, <a href="https://publications.waset.org/abstracts/search?q=discriminant%20analysis" title=" discriminant analysis"> discriminant analysis</a> </p> <a href="https://publications.waset.org/abstracts/27462/predicting-medical-check-up-patient-re-coming-using-sequential-pattern-mining-and-association-rules" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27462.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">640</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">2391</span> The Conceptual Exploration of Comfort Zone by Using Content Analysis </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lilla%20Szab%C3%B3%20Hangya">Lilla Szabó Hangya</a>, <a href="https://publications.waset.org/abstracts/search?q=Szilvia%20Jambori"> Szilvia Jambori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comfort zone is less studied area in the field of psychology. One of the most important definitions is that comfort zone is a psychological state in which things feel familiar to a person with low level of anxiety and stress. But the validity of comfort zone does not confirm till now. The aim of our pilot research is to test which psychological factors could determine how young adults behave during their decision process to stay in one’s comfort zone or to leave it. Every person has a number of comfort zones, so we are not able to measure it directly, only those personality traits which predict if someone leaves his comfort zone easier or harder. In our study at first we wanted to clarify the meaning of comfort zone. 110 young adults (male: 37, female: 73; ages from 18 to 70, average age: 26,6) took part in the study. Beside their demographic datas we asked them what does the comfort zone mean for them. The results showed that the meaning of the comfort zone can be grouped in five dimensions: comfort (49,6 %), leaving it-change (8,1%), ambivalent feelings (10,6%), related to other people (10,6%), pursuit of self-realization (16,8%). Our results demonstrated age related characteristics. For young people at the age of 19 the comfort zone is related to other people, because during adolescents peer relationships become more important. Subjects at the age 20-30 answered that the comfort zone means comfort and stability for them. Their life becomes stable for a while, they are studying or working. But at the age of 25, when they finish university, most of them answered comfort zone means a changing process for them. On the other hand for subjects at the age of 27 the means of the comfort zone is pursuit of self-realization. After that period at the age of 31 when they have families and stable job the stability will also dominant. We saw that the comfort zone has much more meaning besides a pleasant psychological trait. Further we would like to determine which psychological factors relate to comfort zone, and what kind of personality traits could predict leaving or staying in one’s comfort zone. We want to observe the relationship between comfort zone and subjective well-being, life satisfaction self-efficacy or self-esteem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comfort%20zone" title="comfort zone">comfort zone</a>, <a href="https://publications.waset.org/abstracts/search?q=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=personality%20trait" title=" personality trait"> personality trait</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adults" title=" young adults"> young adults</a> </p> <a href="https://publications.waset.org/abstracts/71275/the-conceptual-exploration-of-comfort-zone-by-using-content-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71275.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">340</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">2390</span> Optimizing the Passenger Throughput at an Airport Security Checkpoint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kun%20Li">Kun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Yuzheng%20Liu"> Yuzheng Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiuqi%20Fan"> Xiuqi Fan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-security standard and high efficiency of screening seem to be contradictory to each other in the airport security check process. Improving the efficiency as far as possible while maintaining the same security standard is significantly meaningful. This paper utilizes the knowledge of Operation Research and Stochastic Process to establish mathematical models to explore this problem. We analyze the current process of airport security check and use the M/G/1 and M/G/k models in queuing theory to describe the process. Then we find the least efficient part is the pre-check lane, the bottleneck of the queuing system. To improve passenger throughput and reduce the variance of passengers’ waiting time, we adjust our models and use Monte Carlo method, then put forward three modifications: adjust the ratio of Pre-Check lane to regular lane flexibly, determine the optimal number of security check screening lines based on cost analysis and adjust the distribution of arrival and service time based on Monte Carlo simulation results. We also analyze the impact of cultural differences as the sensitivity analysis. Finally, we give the recommendations for the current process of airport security check process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=queue%20theory" title="queue theory">queue theory</a>, <a href="https://publications.waset.org/abstracts/search?q=security%20check" title=" security check"> security check</a>, <a href="https://publications.waset.org/abstracts/search?q=stochatic%20process" title=" stochatic process"> stochatic process</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo%20simulation" title=" Monte Carlo simulation"> Monte Carlo simulation</a> </p> <a href="https://publications.waset.org/abstracts/72716/optimizing-the-passenger-throughput-at-an-airport-security-checkpoint" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72716.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">200</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">2389</span> Communication Development for Development Communication: Prospects and Challenges of New Media Technologies in South East Zone, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20I.%20Ekwueme">O.

There is an assumption that we cannot have development communication without communication development, but we are not sure if new media technologies contribute to development in the South-East zone, Nigeria. The study employed mixed method and discovered that new media technologies have a very minimal relationship to development in the South-East zone, Nigeria. It was discovered that the media report on development news is basically informative instead of interactive. The South-East zone is scarcely covered unlike other zones. It argued that the communication technologies introduced in Nigeria was as a result of their struggle for independence. It was recommended that media organisations in the South-East zone should give adequate coverage to the zone, and be more interactive. <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=development" title=" development"> development</a>, <a href="https://publications.waset.org/abstracts/search?q=new%20media" title=" new media"> new media</a>, <a href="https://publications.waset.org/abstracts/search?q=technologies" title=" technologies"> technologies</a> </p> <a href="https://publications.waset.org/abstracts/7966/communication-development-for-development-communication-prospects-and-challenges-of-new-media-technologies-in-south-east-zone-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7966.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">340</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">2388</span> CFD Study for Normal and Rifled Tube with a Convergence Check</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharfi%20Dirar">Sharfi Dirar</a>, <a href="https://publications.waset.org/abstracts/search?q=Shihab%20Elhaj"> Shihab Elhaj</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20El%20Fatih"> Ahmed El Fatih</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computational fluid dynamics were used to simulate and study the heated water boiler tube for both normal and rifled tube with a refinement of the mesh to check the convergence.

Protection system consists of many subsystems like relays, circuit breakers, instrument transformers, auxiliary DC system, auxiliary relays etc. Although the fundamental protective and relay operating concepts are similar throughout the world, there are very significant differences in their implementation. These differences arise through different traditions, operating philosophies, experiences and national standards. Protection system mis-operation due to problem in one or more of its subsystem or inadequate knowledge of numerical relay settings and configuration are very common throughout the world. Protection system mis-operation leads to unstable and unreliable grid operation. In this paper we will discuss about the fundamental concepts of protective relaying and the reasons for protection system mis-operation due to one or more of its subsystems. Many real-world case studies of protection system mis-operation from Indian power sector are discussed in detail in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auxiliary%20trip%20relays" title="auxiliary trip relays">auxiliary trip relays</a>, <a href="https://publications.waset.org/abstracts/search?q=bus%20zone" title=" bus zone"> bus zone</a>, <a href="https://publications.waset.org/abstracts/search?q=check%20zone" title=" check zone"> check zone</a>, <a href="https://publications.waset.org/abstracts/search?q=CT%20saturation" title=" CT saturation"> CT saturation</a>, <a href="https://publications.waset.org/abstracts/search?q=dead%20zone%20protection" title=" dead zone protection"> dead zone protection</a>, <a href="https://publications.waset.org/abstracts/search?q=DC%20ground%20faults" title=" DC ground faults"> DC ground faults</a>, <a href="https://publications.waset.org/abstracts/search?q=DMT" title=" DMT"> DMT</a>, <a href="https://publications.waset.org/abstracts/search?q=DR" title=" DR"> DR</a>, <a href="https://publications.waset.org/abstracts/search?q=end%20fault%20protection" title=" end fault protection"> end fault protection</a>, <a href="https://publications.waset.org/abstracts/search?q=instrument%20transformer" title=" instrument transformer"> instrument transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=SOTF" title=" SOTF"> SOTF</a>, <a href="https://publications.waset.org/abstracts/search?q=STUB" title=" STUB"> STUB</a> </p> <a href="https://publications.waset.org/abstracts/171178/protection-system-mis-operations-fundamental-concepts-and-learning-from-indian-power-sector" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171178.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">76</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">2386</span> Solution to Riemann Hypothesis Critical Strip Zone Using Non-Linear Complex Variable Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Manojkumar%20Sabanayagam">Manojkumar Sabanayagam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Riemann hypothesis is an unsolved millennium problem and the search for a solution to the Riemann hypothesis is to study the pattern of prime number distribution. The scope of this paper is to identify the solution for the critical strip and the critical line axis, which has the non-trivial zero solutions using complex plane functions. The Riemann graphical plot is constructed using a linear complex variable function (X+iY) and is applicable only when X>1. But the investigation shows that complex variable behavior has two zones. The first zone is the transformation zone, where the definition of the complex plane should be a non-linear variable which is the critical strip zone in the graph (X=0 to 1). The second zone is the transformed zone (X>1) defined using linear variables conventionally. This paper deals with the Non-linear function in the transformation zone derived using cosine and sinusoidal time lag w.r.t imaginary number ‘i’. The alternate complex variable (Cosθ+i Sinθ) is used to understand the variables in the critical strip zone. It is concluded that the non-trivial zeros present in the Real part 0.5 are because the linear function is not the correct approach in the critical strip.

The quality of antenatal care can be monitored through the content of services received and the kind of information mothers are given during their visit. Objective: The paper tries to examine the association between ANC check-ups and size/ birth weight. It also focuses on investigating the relationship between utilization of recommended prenatal care for mothers and its effect on infant survival in Nepal. Data and methods: This paper uses data from Nepal demographic Health Survey 2011. To understand the relationship bi-variate statistical analysis and logistic regressions has been done. Maternal health care utilization include ANC check-ups i.e. the type of ante-natal care providers, the number and timing of the visit. The various components of the check-ups include intake of iron tablets/syrups, intestinal parasitic drugs, etc. Results: The results show that women who had no antenatal care visits about 40% had small sized babies at the time of birth compared to women to had at least 3 ANC check up. Women who had at least 3 check-ups 17% of the babies have a small size. It has also been found that about 50 % of the women prefer ANC check-ups during pregnancies which have resulted in lowering the infant mortality by about 40% during 1996-2011. Conclusion: Ante natal care check is care and monitoring of the pregnant woman and her foetus throughout pregnancy. ANC checks have an effect on the infant health and child survival. A woman who had at least three check-ups the possibilities of adverse effect on infant health and infant survival was significantly lower. The findings argue for a more enhanced focus on ANC check-ups for improving the maternal and child health in Nepal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal" title="maternal">maternal</a>, <a href="https://publications.waset.org/abstracts/search?q=health" title=" health"> health</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=outcome" title=" outcome"> outcome</a> </p> <a href="https://publications.waset.org/abstracts/44148/maternal-health-care-utilization-and-its-effect-on-pregnancy-outcome-in-nepal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44148.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">240</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">2383</span> Biogenic-Sedimentary Structures of the Ordovician-Khabour Formation from the Northern Thrust Zone, Kurdistan, Iraq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waleed%20Sulaiman%20Shingaly">Waleed Sulaiman Shingaly</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Ordivician-Khabour Formation from the Northern Thrust Zone of Iraqi-Kurdistan comprises between 500 and 800 m of alternating predominantly greenish-grey sandstones, siltstones and shales.

Ethologically these ichnogenera display dwelling and feeding activities of the infaunal organisms. This association of ichnofossils contains elements of the Skolithose and Cruziana ichnofacies. The presence of Skolithos ichnofacies indicates sandy shifting substrate and high energy conditions in foreshore zone while the Cruziana ichnofacies indicate unconsolidated, poorly sorted soft substrate and low energy condition in the shore face/offshore zone. These ichnogenera indicate shoreface-offshore zone of shallow-marine environment for the deposition of the rocks of the Khabour Formation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ichnofossils" title="Ichnofossils">Ichnofossils</a>, <a href="https://publications.waset.org/abstracts/search?q=shoreface-offshore%20zone" title=" shoreface-offshore zone"> shoreface-offshore zone</a>, <a href="https://publications.waset.org/abstracts/search?q=Khabour%20Formation" title=" Khabour Formation"> Khabour Formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Iraq" title=" Iraq"> Iraq</a> </p> <a href="https://publications.waset.org/abstracts/21587/biogenic-sedimentary-structures-of-the-ordovician-khabour-formation-from-the-northern-thrust-zone-kurdistan-iraq" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21587.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">524</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">2382</span> Passenger Preferences on Airline Check-In Methods: Traditional Counter Check-In Versus Common-Use Self-Service Kiosk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cruz%20Queen%20Allysa%20Rose">Cruz Queen Allysa Rose</a>, <a href="https://publications.waset.org/abstracts/search?q=Bautista%20Joymeeh%20Anne"> Bautista Joymeeh Anne</a>, <a href="https://publications.waset.org/abstracts/search?q=Lantoria%20Kaye"> Lantoria Kaye</a>, <a href="https://publications.waset.org/abstracts/search?q=Barretto%20Katya%20Louise"> Barretto Katya Louise</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study presents the preferences of passengers on the quality of service provided by the two airline check-in methods currently present in airports-traditional counter check-in and common-use self-service kiosks. Since a study has shown that airlines perceive self-service kiosks alone are sufficient enough to ensure adequate services and customer satisfaction, and in contrast, agents and passengers stated that it alone is not enough and that human interaction is essential. In reference with former studies that established opposing ideas about the choice of the more favorable airline check-in method to employ, it is the purpose of this study to present a recommendation that shall somehow fill-in the gap between the conflicting ideas by means of comparing the perceived quality of service through the RATER model. Furthermore, this study discusses the major competencies present in each method which are supported by the theories–FIRO Theory of Needs upholding the importance of inclusion, control and affection, and the Queueing Theory which points out the discipline of passengers and the length of the queue line as important factors affecting quality service. The findings of the study were based on the data gathered by the researchers from selected Thomasian third year and fourth year college students currently enrolled in the first semester of the academic year 2014-2015, who have already experienced both airline check-in methods through the implication of a stratified probability sampling. The statistical treatments applied in order to interpret the data were mean, frequency, standard deviation, t-test, logistic regression and chi-square test. The final point of the study revealed that there is a greater effect in passenger preference concerning the satisfaction experienced in common-use self-service kiosks in comparison with the application of the traditional counter check-in. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=traditional%20counter%20check-in" title="traditional counter check-in">traditional counter check-in</a>, <a href="https://publications.waset.org/abstracts/search?q=common-use%20self-service%20Kiosks" title=" common-use self-service Kiosks"> common-use self-service Kiosks</a>, <a href="https://publications.waset.org/abstracts/search?q=airline%20check-in%20methods" title=" airline check-in methods"> airline check-in methods</a> </p> <a href="https://publications.waset.org/abstracts/21176/passenger-preferences-on-airline-check-in-methods-traditional-counter-check-in-versus-common-use-self-service-kiosk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21176.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">406</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">2381</span> Development of Piezoelectric Gas Micropumps with the PDMS Check Valve Design</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiang-Ho%20Cheng">Chiang-Ho Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hon-Yi%20Cheng"> Hon-Yi Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming-Yu%20Lai"> Ming-Yu Lai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the design and fabrication of a novel piezoelectric actuator for a gas micropump with check valve having the advantages of miniature size, light weight and low power consumption. The micropump is designed to have eight major components, namely a stainless steel upper cover layer, a piezoelectric actuator, a stainless steel diaphragm, a PDMS chamber layer, two stainless steel channel layers with two valve seats, a PDMS check valve layer with two cantilever-type check valves and an acrylic substrate. A prototype of the gas micropump, with a size of 52 mm × 50 mm × 5.0 mm, is fabricated by precise manufacturing.

The groundwater-surface water interface, or the hyporheic zone, is known for its impressive self-purification capacity of water bodies. Redox gradients present in this zone provide a wide range of electron acceptors and harbour diverse microbial communities. Biotic transformations of pharmaceuticals in this zone have been demonstrated, but not much information is available on the kind of communities bringing about these transformations. Therefore, bioreactors using sediment from the hyporheic zone of a river in Berlin were set up and fed with iopromide, a recalcitrant iodinated X-ray contrast medium. Iopromide, who’s many oxic and anoxic transformation products have been characterized, was shown to be transformed in such a bioreactor as it passes along the gradient. Many deiodinated transformation products of iopromide could be identified at the outlet of the reactor. In our experiments, it was seen that at the same depths of the column, the transformation of iopromide increased over time. This could be an indication of the microbial communities in the sediment adapting to iopromide. The hyporheic zone, with its varying redox conditions, mainly due to the upwelling and downwelling of surface and groundwater levels, could potentially provide microorganisms with conditions for the complete transformation of recalcitrant pharmaceuticals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iopromide" title="iopromide">iopromide</a>, <a href="https://publications.waset.org/abstracts/search?q=hyporheic%20zone" title=" hyporheic zone"> hyporheic zone</a>, <a href="https://publications.waset.org/abstracts/search?q=recalcitrant%20pharmaceutical" title=" recalcitrant pharmaceutical"> recalcitrant pharmaceutical</a>, <a href="https://publications.waset.org/abstracts/search?q=redox%20gradients" title=" redox gradients"> redox gradients</a> </p> <a href="https://publications.waset.org/abstracts/114009/transformation-of-iopromide-due-to-redox-gradients-in-sediments-of-the-hyporheic-zone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114009.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">128</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">2379</span> Development of a New Piezoelectrically Actuated Micropump for Liquid and Gas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chiang-Ho%20Cheng">Chiang-Ho Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chih-Jer%20Lin"> Chih-Jer Lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun-Ying%20Lee"> Chun-Ying Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to present the design, fabrication and test of a novel piezoelectric actuated, check-valves embedded micropump having the advantages of miniature size, light weight and low power consumption.

The study area consists of microcline granite with grain size of medium to coarse. 2-D Resistivity Imaging survey is used to detect subsurface layer for many years by making measurements on the ground surface.

Climate change, lack of water resources and dried freshwater of Zayandehrood resulted in increased entropy and activated a dynamic which in turn is converted to Playa. The morphometry of 61 polygonal clay microforms in wet zone soil, 52 polygonal clay microforms in pediplain zone soil and 63 microforms in sulfate soil, is evaluated by fractal model. After calculating the microforms’ area–perimeter fractal dimension, their turbulence level was analyzed. Fractal dimensions (DAP) obtained from the microforms’ analysis of pediplain zone, wet zone, and sulfate soils are 1/21-1/39, 1/27-1/44 and 1/29-1/41, respectively, which is indicative of turbulence in these zones. Logarithmic graph drawn for each region also shows that there is a linear relationship between logarithm of the microforms’ area and perimeter so that correlation coefficient (R2) obtained for wet zone is larger than 0.96, for pediplain zone is larger than 0.99 and for sulfated zone is 0.9. Increased turbulence in this region suggests morphological transformation of the system and lagoon’s conversion to a new ecosystem which can be accompanied with serious risks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fractal" title="fractal">fractal</a>, <a href="https://publications.waset.org/abstracts/search?q=Gavkhouni" title=" Gavkhouni"> Gavkhouni</a>, <a href="https://publications.waset.org/abstracts/search?q=microform" title=" microform"> microform</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/81310/geomorphology-evidence-of-climate-change-in-gavkhouni-lagoon-south-east-isfahan-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81310.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">271</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">2375</span> Analysis of the Plastic Zone Under Mixed Mode Fracture in Bonded Composite Repair of Aircraft </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20Oudad">W.

Many industrial examples show the presence of mode II and mixed mode I + II. In the present work the three-dimensional and non-linear finite element method is used to estimate the performance of the bonded composite repair of metallic aircraft structures by analyzing the plastic zone size ahead of repaired cracks under mixed mode loading. The computations are made according to Von Mises and Tresca criteria. The extension of the plastic zone which takes place at the tip of a crack strictly depends on many variables, such as the yield stress of the material, the loading conditions, the crack size and the thickness of the cracked component, The obtained results show that the presence of the composite patch reduces considerably the size of the plastic zone ahead of the crack. The effects of the composite orientation layup (adhesive properties) and the patch thickness on the plastic zone size ahead of repaired cracks were analyzed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack" title="crack">crack</a>, <a href="https://publications.waset.org/abstracts/search?q=elastic-plastic" title=" elastic-plastic"> elastic-plastic</a>, <a href="https://publications.waset.org/abstracts/search?q=J%20integral" title=" J integral"> J integral</a>, <a href="https://publications.waset.org/abstracts/search?q=patch" title=" patch"> patch</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20zone" title=" plastic zone"> plastic zone</a> </p> <a href="https://publications.waset.org/abstracts/30283/analysis-of-the-plastic-zone-under-mixed-mode-fracture-in-bonded-composite-repair-of-aircraft" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30283.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">445</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">2374</span> Development Process and Design Methods for Shared Spaces in Europe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazuyasu%20Yoshino">Kazuyasu Yoshino</a>, <a href="https://publications.waset.org/abstracts/search?q=Keita%20Yamaguchi"> Keita Yamaguchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Toshihiko%20Nishimura"> Toshihiko Nishimura</a>, <a href="https://publications.waset.org/abstracts/search?q=Masashi%20Kawasaki"> Masashi Kawasaki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shared Space, the planning and design concept that allows pedestrians and vehicles to coexist in a street space, has been advocated and developed according to the traffic conditions in each country in Europe.

Meanwhile, in the oscillation period, the oscillations amplitude is not significant. The result of simulation emphasizes that the PID controller designed using the seeker optimization algorithm has a robust function and a better performance for oscillations damping compared to the traditional PID controller. The proposed controller’s performance has been compared to the performance of PID controller regulated with Particle Swarm Optimization (PSO) and. Genetic Algorithm (GA) and Artificial Bee Colony (ABC) algorithms in order to show the superior capability of the proposed SOA in regulating the PID controller. The simulation results emphasize the better performance of the optimized PID controller based on SOA compared to the PID controller optimized with PSO, GA and ABC algorithms. <p
