Shape memory wires are used to reinforced curved composite panel in a smart way. One-dimensional thermodynamic constitutive model by Liang and Rogers is used for estimating the structural recovery stress. The two degrees-of-freedom mass-spring model is used for evaluation of the contact force between the curved composite panel and the impactor. This work is benefited from the Hertzian linear contact model which is linearized for the impact analysis of curved composite panel. The governing equations of curved panel are provided by first-order shear theory and solved by Fourier series related to simply supported boundary condition. For this purpose, the equation of doubly curved panel motion included the uniform in-plane forces is obtained. By the present analysis, the curved panel behavior under low-velocity impact, and also the effect of the impact parameters, the shape memory wire and the curved panel dimensions are studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20curved%20shell" title="doubly curved shell">doubly curved shell</a>, <a href="https://publications.waset.org/abstracts/search?q=SMA%20wire" title=" SMA wire"> SMA wire</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20response" title=" impact response"> impact response</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20material" title=" smart material"> smart material</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloy" title=" shape memory alloy"> shape memory alloy</a> </p> <a href="https://publications.waset.org/abstracts/49593/dynamic-response-of-doubly-curved-composite-shell-with-embedded-shape-memory-alloys-wires" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49593.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">405</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">77</span> Mourning Motivations for Celebrities in Instagram: A Case Study of Mohammadreza Shajarian's Death</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Afshordi">Zahra Afshordi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Instagram, as an everyday life social network, hosts from the ultrasound image of an unborn fetus to the pictures of newly placed gravestones and funerals. It is a platform that allows its users to create a second identity independently from and at the same time in relation to the real space identity. The motives behind this identification are what this article is about. This article studies the motivations of Instagram users mourning for celebrities with a focus on the death of MohammadReza Shajarian. The Shajarian’s death had a wide reflection on Instagram Persian-speaking users. The purpose of this qualitative survey is to comprehend and study the user’s motivations in posting mourning and memorializing content. The methodology of the essay is a hybrid methodology consisting of content analysis and open-ended interviews. The results highlight that users' motives are more than just simple sympathy and include political protest, gaining cultural capital, reaching social status, and escaping from solitude. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20study" title="case study">case study</a>, <a href="https://publications.waset.org/abstracts/search?q=celebrity" title=" celebrity"> celebrity</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=Instagram" title=" Instagram"> Instagram</a>, <a href="https://publications.waset.org/abstracts/search?q=mourning" title=" mourning"> mourning</a>, <a href="https://publications.waset.org/abstracts/search?q=qualitative%20survey" title=" qualitative survey"> qualitative survey</a> </p> <a href="https://publications.waset.org/abstracts/132655/mourning-motivations-for-celebrities-in-instagram-a-case-study-of-mohammadreza-shajarians-death" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132655.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">156</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">76</span> Studying the Theoretical and Laboratory Design of a Concrete Frame and Optimizing Its Design for Impact and Earthquake Resistance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrdad%20Azimzadeh">Mehrdad Azimzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammadreza%20Jabbari"> Seyed Mohammadreza Jabbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Hosseinzadeh%20Alherd"> Mohammadreza Hosseinzadeh Alherd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper includes experimental results and analytical studies about increasing resistance of single-span reinforced concreted frames against impact factor and their modeling according to optimization methods and optimizing the behavior of these frames under impact loads.

The aim of this study is to Bioinformatically identify Rare Codon Clusters (RCC) in proteins structure of HBV. For detection of protein family accession numbers (Pfam) of HBV proteins; used of uni-prot database and Pfam search tool were used. Obtained Pfam IDs were analyzed in Sherlocc program and RCCs in HBV proteins were detected. In further, the structures of TrEMBL entries proteins studied in PDB database and 3D structures of the HBV proteins and locations of RCCs were visualized and studied using Swiss PDB Viewer software. Pfam search tool have found nine significant hits and 0 insignificant hits in 3 frames. Results of Pfams studied in the Sherlocc program show this program not identified RCCs in the external core antigen (PF08290) and truncated HBeAg protein (PF08290). By contrast the RCCs become identified in Hepatitis core antigen (PF00906) Large envelope protein S (PF00695), X protein (PF00739), DNA polymerase (viral) N-terminal domain (PF00242) and Protein P (Pf00336). In HBV genome, seven RCC identified that found in hepatitis core antigen, large envelope protein S and DNA polymerase proteins and proteins structures of TrEMBL entries sequences that reported in Sherlocc program outputs are not complete. Based on situation of RCC in structure of HBV proteins, it suggested those RCCs are important in HBV life cycle. We hoped that this study provide a new and deep perspective in protein research and drug design for treatment of HBV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rare%20codon%20clusters" title="rare codon clusters">rare codon clusters</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20B%20virus" title=" hepatitis B virus"> hepatitis B virus</a>, <a href="https://publications.waset.org/abstracts/search?q=bioinformatic%20study" title=" bioinformatic study"> bioinformatic study</a>, <a href="https://publications.waset.org/abstracts/search?q=infectious%20disease" title=" infectious disease "> infectious disease </a> </p> <a href="https://publications.waset.org/abstracts/24687/bioinformatics-identification-of-rare-codon-clusters-in-proteins-structure-of-hbv" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24687.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">488</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">73</span> Numerical Modeling of Turbulent Natural Convection in a Square Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Sedighi">Mohammadreza Sedighi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Said%20Saidi"> Mohammad Said Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hesamoddin%20Salarian"> Hesamoddin Salarian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A numerical study has been performed to investigate the effect of using different turbulent models on natural convection flow field and temperature distributions in partially heated square cavity compare to benchmark.

Thirty and two different models were studied by different parameters. These studies could calculate displacement at any height of the wall for frictional-cohesive soils. The main purpose of this research is to determine the most effective soil characteristics in reducing the wall displacement. Comparing different models showed that the overall increase in internal friction angle, angle of friction between soil and wall and modulus of elasticity reduce the replacement of the wall. In addition, increase in special weight of soil will increase the wall displacement. Based on results, it can be said that all wall displacements were overturning and in the backfill, soil was bulging. Results show that the highest impact is seen in reducing wall displacement, internal friction angle, and the angle friction between soil and wall. One of the advantages of this study is taking into account all the parameters of the soil and walls replacement distribution in wall and backfill soil. In this paper, using the finite element method and considering all parameters of the soil, we investigated the impact of soil parameter in wall displacement. The aim of this study is to provide the best conditions in reducing the wall displacement and displacement wall and soil distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=retaining%20wall" title="retaining wall">retaining wall</a>, <a href="https://publications.waset.org/abstracts/search?q=fem" title=" fem"> fem</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20and%20wall%20interaction" title=" soil and wall interaction"> soil and wall interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20of%20internal%20friction%20of%20the%20soil" title=" angle of internal friction of the soil"> angle of internal friction of the soil</a>, <a href="https://publications.waset.org/abstracts/search?q=wall%20displacement" title=" wall displacement"> wall displacement</a> </p> <a href="https://publications.waset.org/abstracts/44288/studying-the-impact-of-soil-characteristics-in-displacement-of-retaining-walls-using-finite-element" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44288.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">387</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">71</span> Vertical and Lateral Vibration Analysis of Conventional Elevator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Saviz">Mohammadreza Saviz</a>, <a href="https://publications.waset.org/abstracts/search?q=Sina%20Najafian"> Sina Najafian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents an analytical study of vibration moving elevator and shows the elevator 2D dynamic model to evaluate the vertical and lateral motion.

The study samples were divided into two groups (N1 =360 and N2=354) for exploratory and confirmation analysis. Exploratory factorial analysis was applied to confirm the construct validity of CYRM-28. Results: The results showed that this scale has useful validity content, and the study samples include three factors of individuals, context, and relational in child and youth resilience measure-28. However, from a total of 28 main items, only 15 items could identify these factors. Discussion: The resilience process among young immigrants is mainly explained by individuals, social and cultural conditions. For instance, young immigrants search the resilience process in conditions that caused their immigration. In this context, some questions about the content of security and personal promotion in society could identify three main factors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CYRM-28" title="CYRM-28">CYRM-28</a>, <a href="https://publications.waset.org/abstracts/search?q=factorial%20analysis" title=" factorial analysis"> factorial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=resilience" title=" resilience"> resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=Afghan%20young%20immigrants" title=" Afghan young immigrants"> Afghan young immigrants</a> </p> <a href="https://publications.waset.org/abstracts/138188/resilience-in-refuge-context-the-validity-assessment-using-child-and-youth-resilience-measure-28-among-afghan-young-immigrants-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138188.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">139</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">69</span> Review in Role of Geotextile on Soil Improvement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20Ghavam%20Shirazi">Sandra Ghavam Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20Ramezan%20Shirazi"> Mohsen Ramezan Shirazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Golhashem"> Mohammadreza Golhashem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays by development of construction in modern world new techniques are introduced to civil engineering.

With the possibility of commonly using common resources, an increase of inter-organizational projects, cooperation, outsourcing, and the increase in the number of people who work remotely or flexitime, an extensive and active presence of high-performance teams is a must. Virtual teams are a challenge by themselves. Their members remove the barriers of cultures, time regions and organizations, and they often communicate through electronic devices over considerable distances. Firstly, we examine the management of virtual teams by considering different issues such as cultural and personal diversities, communications and arrangement issues. Then we will examine individuals, processes and the existing tools in a team. The main challenge is managing high-performance virtual teams. First of all, we must examine the concept of performance. Then, we must focus on teams and the best methods of managing them. Constant improvement of performance, together with precisely regulating every individual’s method of working, increases the levels of performance in the course of time. High-performance teams exploit every issue as an opportunity for achieving high performance. And we know that doing projects with high performance is among every organization or team’s objectives. Performance could be measured using many criteria, among which carrying out projects in time, the satisfaction of stakeholders, and not exceeding budgets could be named. Elements such as clear objectives, clearly-defined roles and responsibilities, effective communications, and commitment to collaboration are essential to a team’s effectiveness. Finally, we will examine roles, systems, processes and will carry out a cause-and-effect analysis of different criteria in improving a team’s performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20teams" title="virtual teams">virtual teams</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=process" title=" process"> process</a>, <a href="https://publications.waset.org/abstracts/search?q=improvement" title=" improvement"> improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=effectiveness" title=" effectiveness"> effectiveness</a> </p> <a href="https://publications.waset.org/abstracts/146003/managing-high-performance-virtual-teams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146003.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">148</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">66</span> Explaining the Steps of Designing and Calculating the Content Validity Ratio Index of the Screening Checklist of Preschool Students (5 to 7 Years Old) Exposed to Learning Difficulties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sajed%20Yaghoubnezhad">Sajed Yaghoubnezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sedygheh%20Rezai"> Sedygheh Rezai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Aim: Since currently in Iran, students with learning disabilities are identified after entering school, and with the approach to the gap between IQ and academic achievement, the purpose of this study is to design and calculate the content validity of the pre-school screening checklist (5-7) exposed to learning difficulties. Methods: This research is a fundamental study, and in terms of data collection method, it is quantitative research with a descriptive approach. In order to design this checklist, after reviewing the research background and theoretical foundations, cognitive abilities (visual processing, auditory processing, phonological awareness, executive functions, spatial visual working memory and fine motor skills) are considered the basic variables of school learning. The basic items and worksheets of the screening checklist of pre-school students 5 to 7 years old with learning difficulties were compiled based on the mentioned abilities and were provided to the specialists in order to calculate the content validity ratio index. Results: Based on the results of the table, the validity of the CVR index of the background information checklist is equal to 0.9, and the CVR index of the performance checklist of preschool children (5 to7 years) is equal to 0.78. In general, the CVR index of this checklist is reported to be 0.84.

Examining lexical errors committed by EFL learners is a challenging area of investigation which can shed light on the process of second language acquisition. Despite the considerable number of investigations into grammatical errors, few studies have tackled formal and semantic errors of lexis committed by EFL learners. The current study aimed at examining Persian learners’ formal and semantic errors of lexis in English. To this end, 60 students at three different proficiency levels were asked to write on 10 different topics in 10 separate sessions. Finally, 600 essays written by Persian EFL learners were collected, acting as the corpus of the study. An error taxonomy comprising formal and semantic errors was selected to analyze the corpus. The formal category covered misselection and misformation errors, while the semantic errors were classified into lexical, collocational and lexicogrammatical categories. Each category was further classified into subcategories depending on the identified errors. The results showed that there were 2583 errors in the corpus of 9600 words, among which, 2030 formal errors and 553 semantic errors were identified. The most frequent errors in the corpus included formal error commitment (78.6%), which were more prevalent at the advanced level (42.4%). The semantic errors (21.4%) were more frequent at the low intermediate level (40.5%). Among formal errors of lexis, the highest number of errors was devoted to misformation errors (98%), while misselection errors constituted 2% of the errors. Additionally, no significant differences were observed among the three semantic error subcategories, namely collocational, lexical choice and lexicogrammatical. The results of the study can shed light on the challenges faced by EFL learners in the second language acquisition process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collocational%20errors" title="collocational errors">collocational errors</a>, <a href="https://publications.waset.org/abstracts/search?q=lexical%20errors" title=" lexical errors"> lexical errors</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20EFL%20learners" title=" Persian EFL learners"> Persian EFL learners</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20errors" title=" semantic errors"> semantic errors</a> </p> <a href="https://publications.waset.org/abstracts/103271/the-study-of-formal-and-semantic-errors-of-lexis-by-persian-efl-learners" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103271.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">142</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">64</span> An Agent-Based Modeling and Simulation of Human Muscle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sina%20Saadati">Sina Saadati</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Razzazi"> Mohammadreza Razzazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this article, we have tried to present an agent-based model of human muscle.

It is also useful in the development of a prosthesis that receives the electromyography signals and generates force as a reaction. Since we have focused on computational efficiency in this research, the model can compute the calculations very fast. As far as it concerns prostheses, the model can be known as a charge-efficient method. In this paper, we are about to illustrate an agent-based model.

Despite the significant power of Java, There is not an easy method to render a 3-dimensional human model. In this article, we are about to develop a library which helps modelers present a 3D human model and control it with Java. The library runs two server programs. The first one is a web page server that can connect to any browser and present an HTML code. The second server connects to the browser and controls the movement of the model. So, the modeler will be able to develop a simulation and display a good-looking human model without any knowledge of any graphical tools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agent-based%20modeling%20and%20simulation" title="agent-based modeling and simulation">agent-based modeling and simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20model" title=" human model"> human model</a>, <a href="https://publications.waset.org/abstracts/search?q=graphics" title=" graphics"> graphics</a>, <a href="https://publications.waset.org/abstracts/search?q=Java" title=" Java"> Java</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20systems" title=" distributed systems"> distributed systems</a> </p> <a href="https://publications.waset.org/abstracts/150176/tracy-a-java-library-to-render-a-3d-graphical-human-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150176.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">111</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">61</span> Design and Performance Evaluation of Synchronous Reluctance Machine (SynRM)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Aghazadeh">Hadi Aghazadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Naeimi"> Mohammadreza Naeimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ebrahim%20Afjei"> Seyed Ebrahim Afjei</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Siadatan"> Alireza Siadatan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Torque ripple, maximum torque and high efficiency are important issues in synchronous reluctance machine (SynRM).

The flow is assumed to be multiphase as the formation of vapor by pressure drop is visualized. For pressure and velocity linkage, the coupled algorithm is used. Since the cavitation phenomenon inherently is unsteady, the quasi-steady approach is utilized for saving time and resources in the current study. Schnerr-Sauer cavitation model is used, which was capable of predicting flow behavior both at the initial and final steps of the cavitation process. Two different turbulent models were used in this study to clarify which one is more capable in predicting cavitation inception and super-cavitation. It was found that K-ε was more compatible with the Shnerr-Sauer cavitation model; therefore, the mentioned model is used for the rest of this study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=RANS" title=" RANS"> RANS</a>, <a href="https://publications.waset.org/abstracts/search?q=cavitation" title=" cavitation"> cavitation</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel" title=" fuel"> fuel</a>, <a href="https://publications.waset.org/abstracts/search?q=injector" title=" injector"> injector</a> </p> <a href="https://publications.waset.org/abstracts/138110/utilization-of-schnerr-sauer-cavitation-model-for-simulation-of-cavitation-inception-and-super-cavitation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138110.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">209</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">59</span> Enhancing Predictive Accuracy in Pharmaceutical Sales through an Ensemble Kernel Gaussian Process Regression Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Mirshekari">Shahin Mirshekari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Moradi"> Mohammadreza Moradi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Jafari"> Hossein Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jafari"> Mehdi Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ensaf"> Mohammad Ensaf</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research employs Gaussian Process Regression (GPR) with an ensemble kernel, integrating Exponential Squared, Revised Matern, and Rational Quadratic kernels to analyze pharmaceutical sales data.

Also, three different fluids, namely the University of Wisconsin solution, gelatin, and blood was used to investigate the effect of different fluids on flow inside the coronary artery. A code based on Reynolds Stress Navier Stokes (RANS) equations was written and implemented with the real boundary condition that was calculated based on MRI images. In order to improve the accuracy of the current numerical scheme, hex dominant mesh is utilized.

Fiber Reinforced Polymer (FRP) bar is an acceptable solution to replace steel to mitigate corrosion problem. Since FRP is a brittle material its use in seismic region has been a concern. FRP RC structures can be made ductile by employing a ductile material such as Shape Memory Alloy (SMA) at the plastic hinge region and FRP at the other regions on the other hand SMA is highly resistant to corrosion. Shape Memory Alloy has the unique ability to undergo large inelastic deformation and regain its initial shape through stress removal therefore utilizing composite SMA-FRP bars not only have good corrosion resistance but also have good performance in seismic region. The result show indicate that such composite SMA-FRP bars can substantially reduce the residual drift with adequate energy dissipation capacity during earthquake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=steel%20bar" title="steel bar">steel bar</a>, <a href="https://publications.waset.org/abstracts/search?q=shape%20memory%20alloy" title=" shape memory alloy"> shape memory alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=FRP" title=" FRP"> FRP</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a> </p> <a href="https://publications.waset.org/abstracts/47187/investigate-the-performance-of-sma-frp-composite-bars-in-seismic-regions-under-corrosion-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47187.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">395</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">54</span> Investigate and Solving Analytic of Nonlinear Differential at Vibrations (Earthquake)and Beam-Column, by New Approach “AGM”</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Akbari">Mohammadreza Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Pooya%20Soleimani%20Besheli"> Pooya Soleimani Besheli</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Khalili"> Reza Khalili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Akbari"> Sara Akbari </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, we investigate building structures nonlinear behavior also solving analytic of nonlinear differential at vibrations.

Therefore, it is vital to economize the energy consumption and also find the solution with regard to this issue. One of the systems for the sake of heating the building is floor heating. As a matter of fact, floor heating performance is based on convection and radiation. Actually, in addition to creating a favorable heating condition, this method leads to energy saving. It is the goal of this article to outline the constructal theory and introduce the optimization method in branch networks for floor heating. There are several steps in order to gain this purpose. First of all, the pressure drop through the two points of the network is calculated. This pressure drop is as a function of pipes diameter and other parameters. After that, the amount of heat transfer is determined. Consequently, as a result of the combination of these two functions, the final function will be determined. It is necessary to mention that flow is laminar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=constructal%20theory" title="constructal theory">constructal theory</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=floor%20heating%20system" title=" floor heating system"> floor heating system</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20flow" title=" turbulent flow"> turbulent flow</a> </p> <a href="https://publications.waset.org/abstracts/54375/optimization-of-floor-heating-system-in-the-incompressible-turbulent-flow-using-constructal-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54375.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">319</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">52</span> The Trend of Injuries in Building Fire in Tehran from 2002 to 2012</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Ashouri">Mohammadreza Ashouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Bayatian"> Majid Bayatian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of fire data is a way for the implementation of any plan to improve the level of safety in cities. Such an analysis is able to reveal signs of changes in a given period and can be used as a measure of safety. The information of about 66,341 fires (from 2002 to 2012) released by Tehran Safety Services and Fire-Fighting Organization and data on the population and the number of households provided by Tehran Municipality and the Statistical Yearbook of Iran were extracted. Using the data, the fire changes, the rate of injuries, and mortality rate were determined and analyzed. The rate of injuries and mortality rate of fires per one million population of Tehran were 59.58% and 86.12%, respectively. During the study period, the number of fires and fire stations increased by 104.38% and 102.63%, respectively. Most fires (9.21%) happened in the 4th District of Tehran. The results showed that the recorded fire data have not been systematically planned for fire prevention since one of the ways to reduce injuries caused by fires is to develop a systematic plan for necessary actions in emergency situations. To determine a reliable source for fire prevention, the stages, definitions of working processes and the cause and effect chains should be considered. Therefore, a comprehensive statistical system should be developed for reported and recorded fire data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fire%20statistics" title="fire statistics">fire statistics</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20analysis" title=" fire analysis"> fire analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=accident%20prevention" title=" accident prevention"> accident prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran" title=" Tehran"> Tehran</a> </p> <a href="https://publications.waset.org/abstracts/97571/the-trend-of-injuries-in-building-fire-in-tehran-from-2002-to-2012" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97571.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">184</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">51</span> Design of an Acoustic System for Small-Scale Power Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Judaki">Mohammadreza Judaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Hosein%20Mohammadnezhad%20Shourkaei"> Hosein Mohammadnezhad Shourkaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Usually, noise generated by industrial units, is a pollution and disturbs people and causes problems for human health and sometimes these units will be closed because they cannot eliminate this pollution. Small-scale power plants usually are built close to residential areas, and noise generated by these power plants is an important factor in choosing their location and their design. Materials used to reduce noise are studied by measuring their absorption and reflection index numerically and experimentally. We can use MIKI model (Yasushi Miki, 1990) to simulate absorption index by using software like Ansys or Soundflow and compare calculation results with experimental simulation data. We consider high frequency sounds of power plant engines octave band diagram because dB value of high frequency noise is more noticeable for human ears. To prove this, in this study we first will study calculating octave band of engines exhausts and then we will study acoustic behavior of materials that we will use in high frequencies and this will give us our optimum noise reduction plan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20materials" title="acoustic materials">acoustic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=eliminating%20engine%20noise" title=" eliminating engine noise"> eliminating engine noise</a>, <a href="https://publications.waset.org/abstracts/search?q=octave%20level%20diagram" title=" octave level diagram"> octave level diagram</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20plant%20noise" title=" power plant noise"> power plant noise</a> </p> <a href="https://publications.waset.org/abstracts/93255/design-of-an-acoustic-system-for-small-scale-power-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93255.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">144</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> The Effects of Spark Plasma on Infectious Wound Healing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erfan%20Ghasemi">Erfan Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Khani"> Mohammadreza Khani</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Mahmoudi"> Hamidreza Mahmoudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ali%20Nilforoushzadeh"> Mohammad Ali Nilforoushzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Shokri"> Babak Shokri</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouria%20Akbartehrani"> Pouria Akbartehrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Given the global significance of treating infectious wounds, the goal of this study is to use spark plasma as a new treatment for infectious wounds. To generate spark plasma, a high-voltage (7 kV) and high-frequency (75 kHz) source was used. Infectious wounds in the peritoneum of mice were divided into control and plasma-treated groups at random. The plasma-treated animals received plasma radiation every 4 days for 12 days, for 60 seconds each time. On the 15th day after the first session, the wound in the plasma-treated group had completely healed. The spectra of spark plasma emission and tissue properties were studied. The mechanical resistance of the wound healed in the plasma treatment group was considerably higher than in the control group (p<0.05), according to the findings. Furthermore, histological evidence suggests that wound re-epithelialization is faster in comparison to controls. Angiogenesis and fibrosis (collagen production) were also dramatically boosted in the plasma-treated group, whereas the stage of wound healing inflammation was significantly reduced. Plasma therapy accelerated wound healing by causing considerable wound constriction. The results of this investigation show that spark plasma has an influence on the treatment of infectious wounds. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=infectious%20wounds" title="infectious wounds">infectious wounds</a>, <a href="https://publications.waset.org/abstracts/search?q=mice" title=" mice"> mice</a>, <a href="https://publications.waset.org/abstracts/search?q=spark%20plasma" title=" spark plasma"> spark plasma</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/140938/the-effects-of-spark-plasma-on-infectious-wound-healing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140938.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">295</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> Architectural Design, Low Energy, and Isolation Materials to Have Sustainable Buildings in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammadreza%20Azarnoush">Mohammadreza Azarnoush</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Bayati"> Ali Bayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamileh%20Azarnoush"> Jamileh Azarnoush</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays according to increasing the population all around the world, consuming of fossil fuels increased dramatically. Many believe that most of the atmospheric pollution comes by using fossil fuels. The process of natural sources entering cities shows one of the large challenges in consumption sources management. Nowadays, everyone considers the consumption of fossil fuels and also reduction of consumption civil energy in megacities as playing a key role in solving serious problems such as air pollution, producing greenhouse gasses, global warming, and damage ozone layer. In the construction industry, we should use the materials with the lowest need to energy for making and carrying them, and also the materials which need the lowest energy and expenses to recycling. In this way, the kind of usage material, the way of processing, regional materials, and the adoption to the environment is critical. Otherwise, the isolation should be use and mention in the long term. Accordingly, in this article, we investigate the new ways in order to reduce environmental pollution and save more energy by using materials that are not harmful to the environment, fully insulated materials in buildings, sustainable and diversified buildings, suitable urban design and using solar energy more efficiently in order to reduce energy consumption. <p
