exercises-protocols have been applied to improve low back pain. We compared the effect of supervised exercise therapy and home-based exercise therapy among patients with nonspecific chronic low back pain. Methods: 70 patients with nonspecific chronic low back pain were randomly (using a random number generator, excel) divided into two groups to compare the effects of two types of exercise therapy. After a common educational session to learn how to live with low back pain as well as to use core training protocols to strengthen the muscles, the subjects were randomly assigned to follow supervised exercise therapy (n = 31) or home-based exercise therapy (n = 34) for 20 weeks. Results: Although both types of exercise programs resulted in reduced pain, this factor decreased more significantly in supervised exercise program. All scores of fitness improved significantly in supervised exercise group. But only knee extensor strength score was increased in the home base exercise group. Conclusion: Comparing between two types of exercise, supervised group exercise showed more effective than the other one. Reduction in low back pain severity and improvement in muscle flexibility and strength can be more achieved by using a 20-week supervised exercise program compared to the home-based exercise program in patients with nonspecific chronic low back pain. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title="low back pain">low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=anthropometric%20parameters" title=" anthropometric parameters"> anthropometric parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=supervised%20exercise%20therapy" title=" supervised exercise therapy"> supervised exercise therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=home-based%20exercise%20therapy" title=" home-based exercise therapy"> home-based exercise therapy</a> </p> <a href="https://publications.waset.org/abstracts/70357/comparing-effects-of-supervised-exercise-therapy-versus-home-based-exercise-therapy-on-low-back-pain-severity-muscle-strength-and-anthropometric-parameters-in-patients-with-nonspecific-chronic-low-back-pain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70357.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">329</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> Microstructure Evolution and Pre-transformation Microstructure Reconstruction in Ti-6Al-4V Alloy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shreyash%20Hadke">Shreyash Hadke</a>, <a href="https://publications.waset.org/abstracts/search?q=Manendra%20Singh%20Parihar"> Manendra Singh Parihar</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajesh%20Khatirkar"> Rajesh Khatirkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present investigation, the variation in the microstructure with the changes in the heat treatment conditions i.e. temperature and time was observed. Ti-6Al-4V alloy was subject to solution annealing treatments in β (1066C) and α+β phase (930C and 850C) followed by quenching, air cooling and furnace cooling to room temperature respectively. The effect of solution annealing and cooling on the microstructure was studied by using optical microscopy (OM), scanning electron microscopy (SEM), electron backscattered diffraction (EBSD) and x-ray diffraction (XRD). The chemical composition of the β phase for different conditions was determined with the help of energy dispersive spectrometer (EDS) attached to SEM. Furnace cooling resulted in the development of coarser structure (α+β), while air cooling resulted in much finer structure with widmanstatten morphology of α at the grain boundaries. Quenching from solution annealing temperature formed α’ martensite, their proportion being dependent on the temperature in β phase field. It is well known that the transformation of β to α follows Burger orientation relationship (OR). In order to reconstruct the microstructure of parent β phase, a MATLAB code was written using neighbor-to-neighbor, triplet method and Tari’s method. The code was tested on the annealed samples (1066C solution annealing temperature followed by furnace cooling to room temperature). The parent phase data thus generated was then plotted using the TSL-OIM software. The reconstruction results of the above methods were compared and analyzed. The Tari’s approach (clustering approach) gave better results compared to neighbor-to-neighbor and triplet method but the time taken by the triplet method was least compared to the other two methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ti-6Al-4V%20alloy" title="Ti-6Al-4V alloy">Ti-6Al-4V alloy</a>, <a href="https://publications.waset.org/abstracts/search?q=microstructure" title=" microstructure"> microstructure</a>, <a href="https://publications.waset.org/abstracts/search?q=electron%20backscattered%20diffraction" title=" electron backscattered diffraction"> electron backscattered diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=parent%20phase%20reconstruction" title=" parent phase reconstruction"> parent phase reconstruction</a> </p> <a href="https://publications.waset.org/abstracts/24632/microstructure-evolution-and-pre-transformation-microstructure-reconstruction-in-ti-6al-4v-alloy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24632.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">446</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">65</span> HD-WSComp: Hypergraph Decomposition for Web Services Composition Based on QoS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samah%20Benmerbi">Samah Benmerbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Amroun"> Kamal Amroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkamel%20Tari"> Abdelkamel Tari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increasing number of Web service (WS)providers throughout the globe, have produced numerous Web services providing the same or similar functionality. Therefore, there is a need of tools developing the best answer of queries by selecting and composing services with total transparency. This paper reviews various QoS based Web service selection mechanisms and architectures which facilitate qualitatively optimal selection, in other fact Web service composition is required when a request cannot be fulfilled by a single web service. In such cases, it is preferable to integrate existing web services to satisfy user’s request. We introduce an automatic Web service composition method based on hypergraph decomposition using hypertree decomposition method. The problem of selection and the composition of the web services is transformed into a resolution in a hypertree by exploring the relations of dependency between web services to get composite web service via employing an execution order of WS satisfying global request. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=web%20service" title="web service">web service</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service%20selection" title=" web service selection"> web service selection</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service%20composition" title=" web service composition"> web service composition</a>, <a href="https://publications.waset.org/abstracts/search?q=QoS" title=" QoS"> QoS</a>, <a href="https://publications.waset.org/abstracts/search?q=hypergraph%20decomposition" title=" hypergraph decomposition"> hypergraph decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=BE%20hypergraph%20decomposition" title=" BE hypergraph decomposition"> BE hypergraph decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=hypertree%20resolution" title=" hypertree resolution"> hypertree resolution</a> </p> <a href="https://publications.waset.org/abstracts/23723/hd-wscomp-hypergraph-decomposition-for-web-services-composition-based-on-qos" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23723.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">509</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> Photon-Electron Interaction in the Different Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Borji">Vahid Borji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The interaction between photons and particles is a common phenomenon in nature that is discussed in order to obtain information about the environment and the conditions governing the phenomena. In the astrophysics, like others, we study these interactions to get useful knowledge and can be predict aftercoming events. One of the events is the transition of photon beam through medium with special conditions, like shocked medium. In our discussion, we have studied this situation and obtained results for different conditions that transition of photon depends on the energy of photon and distributions of electrons in medium. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cross%20section" title="cross section">cross section</a>, <a href="https://publications.waset.org/abstracts/search?q=astrophysics" title=" astrophysics"> astrophysics</a>, <a href="https://publications.waset.org/abstracts/search?q=GRB" title=" GRB"> GRB</a>, <a href="https://publications.waset.org/abstracts/search?q=photon" title=" photon"> photon</a> </p> <a href="https://publications.waset.org/abstracts/163852/photon-electron-interaction-in-the-different-medium" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163852.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">89</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">63</span> Elephant Herding Optimization for Service Selection in QoS-Aware Web Service Composition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samia%20Sadouki%20Chibani">Samia Sadouki Chibani</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelkamel%20Tari"> Abdelkamel Tari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Web service composition combines available services to provide new functionality. Given the number of available services with similar functionalities and different non functional aspects (QoS), the problem of finding a QoS-optimal web service composition is considered as an optimization problem belonging to NP-hard class. Thus, an optimal solution cannot be found by exact algorithms within a reasonable time. In this paper, a meta-heuristic bio-inspired is presented to address the QoS aware web service composition; it is based on Elephant Herding Optimization (EHO) algorithm, which is inspired by the herding behavior of elephant group. EHO is characterized by a process of dividing and combining the population to sub populations (clan); this process allows the exchange of information between local searches to move toward a global optimum. However, with Applying others evolutionary algorithms the problem of early stagnancy in a local optimum cannot be avoided. Compared with PSO, the results of experimental evaluation show that our proposition significantly outperforms the existing algorithm with better performance of the fitness value and a fast convergence. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-inspired%20algorithms" title="bio-inspired algorithms">bio-inspired algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=elephant%20herding%20optimization" title=" elephant herding optimization"> elephant herding optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=QoS%20optimization" title=" QoS optimization"> QoS optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=web%20service%20composition" title=" web service composition"> web service composition</a> </p> <a href="https://publications.waset.org/abstracts/64274/elephant-herding-optimization-for-service-selection-in-qos-aware-web-service-composition" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64274.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">327</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> In-Situ Synthesis of Zinc-Containing MCM-41 and Investigation of Its Capacity for Removal of Hydrogen Sulfide from Crude Oil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nastaran%20Hazrati">Nastaran Hazrati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Akbar%20Miran%20Beigi"> Ali Akbar Miran Beigi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Abdouss"> Majid Abdouss</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Vahid"> Amir Vahid</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydrogen sulfide is the most toxic gas of crude oil.

However, the complexities of the chemical composition of agarwood itself is the main challenge for establishment of an effective recovery method, which is able to ensure uniform qualities and standard for each batch of essential oil production. Agarwood markers are actually a blend of volatile and non-volatile compounds. While volatile molecules could be easily retrieved by the present distillation technique, the high solubility properties are the limiting factor for the latter. With regard to this, an elementary chemistry resolution study had been performed on commercial agarwood essential oil-water mixture, by the application of preparative HPLC and FTIR. Interpretation of the results leads to the theoretical postulation that, agarwood water mixture comprise of agarospirol, jinkohol, jinkoh eremol and khusenol. This study provides a pinpoint on the chemical characteristics of water soluble (non-volatile) agarwood compounds, therefore, will be an insight for researchers to develop a more strategic technique for their extraction. Thereafter the optimum quality of this essential oil could be controlled in a more improved way. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Agarwood" title="Agarwood">Agarwood</a>, <a href="https://publications.waset.org/abstracts/search?q=Aquillaria%20Malaccensis" title=" Aquillaria Malaccensis"> Aquillaria Malaccensis</a>, <a href="https://publications.waset.org/abstracts/search?q=agarospirol" title=" agarospirol"> agarospirol</a>, <a href="https://publications.waset.org/abstracts/search?q=jinkohol" title=" jinkohol"> jinkohol</a>, <a href="https://publications.waset.org/abstracts/search?q=jinkoh%20eremol" title=" jinkoh eremol"> jinkoh eremol</a>, <a href="https://publications.waset.org/abstracts/search?q=khusenol" title=" khusenol"> khusenol</a> </p> <a href="https://publications.waset.org/abstracts/16900/a-fundamental-study-on-the-molecular-chemistry-of-agarwood-water-mixture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16900.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">548</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> Fast Terminal Sliding Mode Controller For Quadrotor UAV</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Tabrizi">Vahid Tabrizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20GHasemi">Reza GHasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Vali">Ahmadreza Vali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents robust nonlinear control law for a quadrotor UAV using fast terminal sliding mode control.

However, many groups and different attitudes call themselves Salafis, but they all have common characteristics, the main of which is radical and retrograde interpretation of Islamic sources. Taqi Ad-Din Ahmad ibn Taymiyyah in the Muslim world was the first thinker who established these thoughts. The authors of this article initially tried to express the meaning of Salafism and its appellation in order to focus on the beliefs and thoughts of Ibn Taymiyyah. In this way, it was tried to extract the intellectual foundations of Ibn Taymiyya from the literature and scientific works of his own using a descriptive-analytical method. Extreme focus on the appearance of Quranic phrases and opposition to any new thing that did not exist in Qur'an, Sunnah and the first 3 centuries of Islam, are among the central feature of his thoughts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salafism" title="Salafism">Salafism</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibn%20Taymiyyah" title=" Ibn Taymiyyah"> Ibn Taymiyyah</a>, <a href="https://publications.waset.org/abstracts/search?q=radical%20literalism" title=" radical literalism"> radical literalism</a>, <a href="https://publications.waset.org/abstracts/search?q=monotheism" title=" monotheism"> monotheism</a>, <a href="https://publications.waset.org/abstracts/search?q=polytheism" title=" polytheism"> polytheism</a>, <a href="https://publications.waset.org/abstracts/search?q=takfir" title=" takfir"> takfir</a> </p> <a href="https://publications.waset.org/abstracts/18351/investigating-salafism-and-its-founder" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18351.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">621</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Failure Analysis of a 304 Stainless Steel Flange Crack at Pipeline Transportation of Ethylene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parisa%20Hasanpour">Parisa Hasanpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Borooghani"> Bahram Borooghani</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Asadi"> Vahid Asadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current research, a catastrophic failure of a 304 stainless steel flange at pipeline transportation of ethylene in a petrochemical refinery was studied.

Variety used was Shiroudi as a high yielding variety. Nitrogen management was in two methods. Amount of nitrogen at four levels (30, 60, 90, and 120 Kg N ha-1 and control) and nitrogen-splitting at four levels (T1: 50% in base + 50% in maximum tillering stage, T2= 33.33% basal +33.33% in maximum tillering stage +33.33% in panicle initiation stage, T3=25% basal+37.5% in maximum tillering stage +37.5% in panicle initiation stage, T4: 25% in basal + 25% in maximum tillering stage + 50% in panicle initiation stage). Results showed that nitrogen traits, total grain number, filled spikelets, panicle number per m2 had a significant correlation with grain yield. Results related to calibrated and validation of rice model methods indicated that correlation between rice yield and yield components was accurate. The correlation between panicle length and grain yield was minimum. Physiological indices was simulated with low accuracy. According to results, investigation of the correlation between rice traits in physiological, morphological and phenological characters and yield by modeling and simulation methods are very useful. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rice" title="rice">rice</a>, <a href="https://publications.waset.org/abstracts/search?q=physiology" title=" physiology"> physiology</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=yield%20traits" title=" yield traits "> yield traits </a> </p> <a href="https://publications.waset.org/abstracts/16185/assessment-the-correlation-of-rice-yield-traits-by-simulation-and-modelling-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16185.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Application of Imperialist Competitive Algorithm for Optimal Location and Sizing of Static Compensator Considering Voltage Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Rashtchi">Vahid Rashtchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashkan%20Pirooz"> Ashkan Pirooz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper applies the Imperialist Competitive Algorithm (ICA) to find the optimal place and size of Static Compensator (STATCOM) in power systems.

Many institutions in the world are defining their sustainable development path and some are following existing green building and sustainable campus rating/ranking systems, guidelines. In the context of higher education, Turkish universities have limited academic, social and financial support related to sustainable living, building, and campus studies. While some research has been conducted in the last 60 years by farsighted academics, most of these works are based on individuals’ or small organizations’ own interests and efforts, and they are not known enough by the population of universities and possible prospective investors. Regarding the recent fast and uncontrolled growth in the Turkish Higher Education environment, setting a campus sustainability indicator set is a necessity for sustainable development of universities. The main objective of this paper is to specify the applicable sustainability indicators in the national context of Turkey, and propose a model guideline for sustainable Turkish university campuses. The analysis of Turkish legislation on environmental issues, special conditions of Turkish Higher Education system, and Turkey’s environmental risks and challenges set the backbone of the study and distinguish the set of indicators from generalized guidelines. Finally, the paper outlines some concrete suggestions for Turkish Universities to integrate sustainability efforts in their regional context. It will be useful for campus sustainability managers and planners, interested in developing action plans in their national and regional scope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=campus%20sustainability" title="campus sustainability">campus sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability%20indicators" title=" sustainability indicators"> sustainability indicators</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkish%20universities" title=" Turkish universities"> Turkish universities</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20campus%20sustainability%20action%20plan" title=" national campus sustainability action plan"> national campus sustainability action plan</a> </p> <a href="https://publications.waset.org/abstracts/43668/framing-a-turkish-campus-sustainability-indicator-set" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43668.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">258</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> Justyna Skrzyńska, Zdzisław Kobos, Zbigniew Wochyński</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Bairami%20Rad">Vahid Bairami Rad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the tremendous progress in computer technology in the last decades, the capabilities of computers increased enormously and working with a computer became a normal activity for nearly everybody. With all the possibilities a computer can offer, humans and their interaction with computers are now a limiting factor. This gave rise to a lot of research in the field of HCI (human computer interaction) aiming to make interaction easier, more intuitive, and more efficient. To research eye gaze based interfaces it is necessary to understand both sides of the interaction–the human eye and the eye tracker. The first section gives an overview on the anatomy of the eye. The second section accuracy and calibration issue. The subsequent section presents data from a user study where eye movements have been recorded while watching a video and while surfing the Internet. Statistics on the eye movement during these tasks for several individuals provide typical values and ranges for fixation times and saccade lengths and are the foundation for discussions in later chapters. The data also reveal typical limitations of eye trackers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title="human computer interaction">human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=gaze%20tracking" title=" gaze tracking"> gaze tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=calibration" title=" calibration"> calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=eye%20movement" title=" eye movement"> eye movement</a> </p> <a href="https://publications.waset.org/abstracts/29656/justyna-skrzynska-zdzislaw-kobos-zbigniew-wochynski" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29656.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">537</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Investigating the Energy Gap and Wavelength of (AlₓGa₁₋ₓAs)ₘ/(GaAs)ₙ Superlattices in Terms of Material Thickness and Al Mole Fraction Using Empirical Tight-Binding Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matineh%20Sadat%20Hosseini%20Gheidari">Matineh Sadat Hosseini Gheidari</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Reza%20Yazdanpanah"> Vahid Reza Yazdanpanah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we used the empirical tight-binding method (ETBM) with sp3s* approximation and considering the first nearest neighbor with spin-orbit interactions in order to model superlattice structure (SLS) of (AlₓGa₁₋ₓAs)ₘ/(GaAs)ₙ grown on GaAs (100) substrate at 300K. In the next step, we investigated the behavior of the energy gap and wavelength of this superlattice in terms of different thicknesses of core materials and Al mole fractions. As a result of this survey, we found out that as the Al composition increases, the energy gap of this superlattice has an upward trend and ranges from 1.42-1.63 eV.

Better e-service quality will enhance the relationship with customers and their satisfaction. So the measurement of eservice quality is very important but it is a complex process due to the complex nature of services. Literature predicts that there is a lack of universal definition of e-service quality. The e-service quality measures in banking have great importance in achieving high customer base. This paper proposes a conceptual model for measuring e-service quality in Iranian Banking Iran. Nine dimensions reliability, ease of use, personalization, security and trust, website aesthetic, responsiveness, contact and speed of delivery had been identified. The results of this paper may help to develop a proper scale to measure the e-service quality in Iranian Banking Industry, which may assist to maintain and improve the performance and effectiveness of e-service quality to retain customers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electronic%20banking" title="electronic banking">electronic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimensions" title=" Dimensions"> Dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20service%20quality" title=" customer service quality"> customer service quality</a>, <a href="https://publications.waset.org/abstracts/search?q=electronic" title=" electronic"> electronic</a>, <a href="https://publications.waset.org/abstracts/search?q=communication" title=" communication"> communication</a> </p> <a href="https://publications.waset.org/abstracts/29099/evaluating-electronic-service-quality-in-banking-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29099.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">499</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Algorithms used in Spatial Data Mining GIS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Bairami%20Rad">Vahid Bairami Rad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Extracting knowledge from spatial data like GIS data is important to reduce the data and extract information. Therefore, the development of new techniques and tools that support the human in transforming data into useful knowledge has been the focus of the relatively new and interdisciplinary research area ‘knowledge discovery in databases’. Thus, we introduce a set of database primitives or basic operations for spatial data mining which are sufficient to express most of the spatial data mining algorithms from the literature. This approach has several advantages. Similar to the relational standard language SQL, the use of standard primitives will speed-up the development of new data mining algorithms and will also make them more portable. We introduced a database-oriented framework for spatial data mining which is based on the concepts of neighborhood graphs and paths. A small set of basic operations on these graphs and paths were defined as database primitives for spatial data mining. Furthermore, techniques to efficiently support the database primitives by a commercial DBMS were presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spatial%20data%20base" title="spatial data base">spatial data base</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20discovery%20database" title=" knowledge discovery database"> knowledge discovery database</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=spatial%20relationship" title=" spatial relationship"> spatial relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20data%20mining" title=" predictive data mining"> predictive data mining</a> </p> <a href="https://publications.waset.org/abstracts/29004/algorithms-used-in-spatial-data-mining-gis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29004.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">460</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">45</span> The Effect of Grading Characteristics on the Shear Strength and Mechanical Behavior of Granular Classes of Sands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salah%20Brahim%20Belakhdar">Salah Brahim Belakhdar</a>, <a href="https://publications.waset.org/abstracts/search?q=Tari%20Mohammed%20Amin"> Tari Mohammed Amin</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafai%20Abderrahmen"> Rafai Abderrahmen</a>, <a href="https://publications.waset.org/abstracts/search?q=Amalsi%20Bilal"> Amalsi Bilal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Shear strength of sandy soils has been considered as the important parameter to study the stability of different civil engineering structures when subjected to monotonic, cyclic, and earthquake loading conditions. The proposed research investigated the effect of grading characteristics on the shear strength and mechanical behaviour of granular classes of sands mixed with salt in loose and dense states (Dr=15% and 90%). The laboratory investigation aimed at understanding the extent or degree at which shear strength of sand-silt mixture soil is affected by its gradation under static loading conditions. For the purpose of clarifying and evaluating the shear strength characteristics of sandy soils, a series of Casagrande shear box tests were carried out on different reconstituted samples of sand-silt mixtures with various gradations. The soil samples were tested under different normal stresses (100, 200, and 300 kPa). The results from this laboratory investigation were used to develop insight into the shear strength response of sand and sand-silt mixtures under monotonic loading conditions. The analysis of the obtained data revealed that the grading characteristics (D10, D50, Cu, ESR, and MGSR) have a significant influence on the shear strength response. It was found that shear strength can be correlated to the grading characteristics for the sand-silt mixture. The effective size ratio (ESR) and mean grain size ratio (MGSR) appear as pertinent parameters to predict the shear strength response of the sand-silt mixtures for soil gradation under study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title="mechanical behavior">mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=silty%20sand" title=" silty sand"> silty sand</a>, <a href="https://publications.waset.org/abstracts/search?q=friction%20angle" title=" friction angle"> friction angle</a>, <a href="https://publications.waset.org/abstracts/search?q=cohesion" title=" cohesion"> cohesion</a>, <a href="https://publications.waset.org/abstracts/search?q=fines%20content" title=" fines content"> fines content</a> </p> <a href="https://publications.waset.org/abstracts/26025/the-effect-of-grading-characteristics-on-the-shear-strength-and-mechanical-behavior-of-granular-classes-of-sands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26025.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">373</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Computational Cell Segmentation in Immunohistochemically Image of Meningioma Tumor Using Fuzzy C-Means and Adaptive Vector Directional Filter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Anari">Vahid Anari</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Shahmohammadi"> Leila Shahmohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Diagnosing and interpreting manually from a large cohort dataset of immunohistochemically stained tissue of tumors using an optical microscope involves subjectivity and also is tedious for pathologist specialists.

It has various advantages like connecting the world, simplifying the difficult tasks done in past etc. Simultaneously it has demerits also; that is lack of authenticity and internet addiction. To find out the problems of internet addiction, a study conducted among the Postgraduate students of Pondicherry University and collected 454 samples. The study strictly focused to identify the internet addiction among students, influence and interdependence of personality on internet addiction among first years and second years. To evaluate this, we used two major analysis, these are Confirmatory Factor Analysis (CFA) to predict the internet addiction with the observed data and Logistic Regression to identify the difference between first years and second years in the case of internet addiction. Before applying to the core analysis, the data applied to some preliminary tests to check the model fit. The empirical findings shows that , the students of Pondicherry University are very much addicted to the internet, But there is no such huge difference between first years and second years in case of internet addiction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20addiction" title="internet addiction">internet addiction</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=Pondicherry%20University" title=" Pondicherry University"> Pondicherry University</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20study" title=" empirical study"> empirical study</a> </p> <a href="https://publications.waset.org/abstracts/24138/internet-addiction-among-students-an-empirical-study-in-pondicherry-university" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24138.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">459</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Factors Affecting Bus Use as a Sustainable Mode of Transportation: Insights from Kerman, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Rahmani">Fatemeh Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Navid%20Nadimi"> Navid Nadimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Khalifeh"> Vahid Khalifeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the near future, cities with medium populations will face traffic congestion, air pollution, high fuel consumption, and noise pollution. It is possible to improve the sustainability of cities by utilizing public transportation. A study of the factors that influence citizens' bus usage in medium-sized cities is presented in this paper. For this purpose, Kerman's citizens were surveyed online. The model was based on a binary logistic regression. A descriptive analysis revealed that simple measures like renewing the fleet, upgrading the stations, establishing a schedule program, and cleaning the buses could improve passenger satisfaction. In addition, the modeling results showed that future traffic congestion can be prevented by implementing road and parking lot pricing plans. Further, as the number and length of trips increase, the probability of citizens taking the bus increases. In conclusion, Kerman's bus system is both secure and fast, but these two characteristics can be improved to increase bus ridership. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainability" title="sustainability">sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=transportation" title=" transportation"> transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=bus" title=" bus"> bus</a>, <a href="https://publications.waset.org/abstracts/search?q=congestion" title=" congestion"> congestion</a>, <a href="https://publications.waset.org/abstracts/search?q=satisfaction" title=" satisfaction"> satisfaction</a> </p> <a href="https://publications.waset.org/abstracts/193855/factors-affecting-bus-use-as-a-sustainable-mode-of-transportation-insights-from-kerman-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193855.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">10</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Specialized Phytochemical Properties of Stachys inflata Eco-Types in Different Ecological Circumstances of Southern Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ghasem%20Khodahami">Ghasem Khodahami</a>, <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Rowshan"> Vahid Rowshan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Pakparvar"> Mojtaba Pakparvar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stachys forms one of the largest genera in the flowering plant family Lamiaceae. The number of species in the genus is estimated from about 300 to about 450 and comprises some 34 species in Iran. This genus is one of the richest sources of diterpenes which are particularly interesting because of their ecological role as antifeedants against different species of insects and for their role as the medicinal properties of the plants. The ecological distribution of Stachys inflata was studied and the resulted eco-types were sampled from four regions ranging 230-340 mm of rainfall and 1690-2125 m a.s.l of height In Fars Province Southern Iran. The essential oils of air-dried samples were obtained by hydrodistillation and analyzed by gas chromatography and gas chromatography/mass spectrometry. The number of secondary metabolites varied from 25 to 50 depending to ecological conditions. The main compounds in these areas were: Germacrene D, Bicyclogermacrene, spathulenol, δ-cadinene.

Based on atomic force microscopy (AFM) results, the rejuvenation process leads to an increase in nanoscale spatial heterogeneity manifested by the intensification of the local viscoelastic response of the BMG nanostructure. It means that the rejuvenation process induces more loose-packing structures which behave towards an external load in a viscoelastic way. Hence, it is suggested that the alteration of such heterogeneity may be attributed to the variation of positional atomic rearrangement during the evolution of structural rejuvenation. On the other side, the synchrotron X-ray diffraction (XRD) results indicate that the rejuvenation intensifies the variation of internal stresses at the atomic level. This conclusion unfolds that the increase of atomic-level stresses during rejuvenation induces structural disordering and nanoscale heterogeneity in the amorphous material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bulk%20metallic%20glass" title="bulk metallic glass">bulk metallic glass</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title=" heterogeneity"> heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=rejuvenation" title=" rejuvenation"> rejuvenation</a>, <a href="https://publications.waset.org/abstracts/search?q=nanostructure" title=" nanostructure"> nanostructure</a> </p> <a href="https://publications.waset.org/abstracts/121311/inherent-relation-between-atomic-level-stresses-and-nanoscale-spatial-heterogeneity-in-a-rejuvenated-bulk-metallic-glass" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121311.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">38</span> Automatic Detection of Proliferative Cells in Immunohistochemically Images of Meningioma Using Fuzzy C-Means Clustering and HSV Color Space</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Anari">Vahid Anari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mina%20Bakhshi"> Mina Bakhshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Visual search and identification of immunohistochemically stained tissue of meningioma was performed manually in pathologic laboratories to detect and diagnose the cancers type of meningioma.

Dataset including 150 images are used to test the scheme. The scheme uses Fuzzy C-means algorithm as a color clustering method based on perceptually uniform hue, saturation, value (HSV) color space. Since the cells are distinguishable by the human eye, the accuracy and stability of the algorithm are quantitatively compared through application to a wide variety of real images. <p
