an image processing algorithm to measure water droplets characteristics during dropwise condensation on pillared surfaces. The main problem in this process is the similarity between shape and size of water droplets and the pillars. The developed method divides droplets into four main groups based on their size and applies the corresponding algorithm to segment each group. These algorithms generate binary images of droplets based on both their geometrical and intensity properties. The information related to droplets evolution during time including mean radius and drops number per unit area are then extracted from the binary images. The developed image processing algorithm is verified using manual detection and applied to two different sets of images corresponding to two kinds of pillared surfaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dropwise%20condensation" title="dropwise condensation">dropwise condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=textured%20surface" title=" textured surface"> textured surface</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20processing" title=" image processing"> image processing</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed" title=" watershed"> watershed</a> </p> <a href="https://publications.waset.org/abstracts/77857/segmentation-of-gray-scale-images-of-dropwise-condensation-on-textured-surfaces" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77857.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">223</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">25</span> Comparing Friction Force Between Track and Spline Using graphite, Mos2, PTFE, and Silicon Dry Lubricant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20De%20Maaijer">M.

With the advancement of research on recycled aggregates, it has become possible to replace natural aggregates with recycled aggregates and to achieve a reduction in energy consumption of materials during construction. The purpose of this paper is to quantitatively compare the emergy consumption of natural aggregate concrete (NAC) and recycled aggregate concrete (RAC). To do so, the emergy analysis method is adopted. Using this technique, it can effectively analyze different forms of energy and substance. The main analysis object is the direct and indirect emergy consumption of the stages in concrete production. Therefore, for indirect energy, consumption of production machinery and transportation vehicle also need to be considered. Finally, the emergy values required to produce the two concrete types are compared to analyze whether the RAC can reduce emergy consumption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20construction" title="sustainable construction">sustainable construction</a>, <a href="https://publications.waset.org/abstracts/search?q=NAC" title=" NAC"> NAC</a>, <a href="https://publications.waset.org/abstracts/search?q=RAC" title=" RAC"> RAC</a>, <a href="https://publications.waset.org/abstracts/search?q=emergy" title=" emergy"> emergy</a>, <a href="https://publications.waset.org/abstracts/search?q=concrete" title=" concrete"> concrete</a> </p> <a href="https://publications.waset.org/abstracts/116662/construction-sustainability-improvement-through-using-recycled-aggregates-in-concrete-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/116662.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">149</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">22</span> Interaction of between Cd and Zn in Barley (Hordeum vulgare L.)

Children, including 280 female students of Shahriar police officers, were selected by random sampling method, and they have been investigated through Alfred B. Hillburn's family emotional climate questionnaire (1964), King and Ammon's emotional expression questionnaire (1990), and Pitrinen, Sweeney, and Falto's academic well-being questionnaire (2014). The data were analyzed using statistical methods of correlation coefficient and stepwise multiple regression under the SPSS23 program. The results reveal that the variables of family emotional climate and emotional expression can explain 36.4% of the variance in academic well-being. This finding reveals that with an increase of standard deviation on the scores of family emotional climate and emotional expression, 0.513 and 0.155 standard deviations are added to the scores of academic well-being, respectively. The emotional climate of the family has a superior distinctive role in predicting the educational well-being of female students. Thus, the emotional climate of the family and the style of emotional expression play a meaningful role in the academic well-being of students with the military parent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emotional%20climate" title="emotional climate">emotional climate</a>, <a href="https://publications.waset.org/abstracts/search?q=family" title=" family"> family</a>, <a href="https://publications.waset.org/abstracts/search?q=emotional%20expression%20style" title=" emotional expression style"> emotional expression style</a>, <a href="https://publications.waset.org/abstracts/search?q=academic%20well-being" title=" academic well-being"> academic well-being</a> </p> <a href="https://publications.waset.org/abstracts/154692/the-role-of-familys-emotional-climate-and-emotional-expression-style-in-academic-well-being-of-students-with-military-parent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154692.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">109</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">20</span> Investigation on Mesh Sensitivity of a Transient Model for Nozzle Clogging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Barati">H.

Key steps of clogging are considered: transport of particles by turbulent flow towards the nozzle wall; interactions between fluid flow and nozzle wall, and the adhesion of the particle on the wall; the growth of the clog layer and its interaction with the flow. The current paper is to investigate the mesh (size and type) sensitivity of the model in both two and three dimensions. It is found that the algorithm for clog growth alone excluding the flow effect is insensitive to the mesh type and size, but the calculation including flow becomes sensitive to the mesh quality. The use of 2D meshes leads to overestimation of the clog growth because the 3D nature of flow in the boundary layer cannot be properly solved by 2D calculation. 3D simulation with tetrahedron mesh can also lead to an error estimation of the clog growth. A mesh-independent result can be achieved with hexahedral mesh, or at least with triangular prism (inflation layer) for near-wall regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clogging" title="clogging">clogging</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20casting" title=" continuous casting"> continuous casting</a>, <a href="https://publications.waset.org/abstracts/search?q=inclusion" title=" inclusion"> inclusion</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=submerged%20entry%20nozzle" title=" submerged entry nozzle"> submerged entry nozzle</a> </p> <a href="https://publications.waset.org/abstracts/74984/investigation-on-mesh-sensitivity-of-a-transient-model-for-nozzle-clogging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74984.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">283</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">19</span> Aerodynamic Performance of a Pitching Bio-Inspired Corrugated Airfoil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Zarafshani">Hadi Zarafshani</a>, <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour"> Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Teimori"> Shahin Teimori</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Barati"> Sara Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, the aerodynamic performance of a rigid two-dimensional pitching bio-inspired corrugate airfoil was numerically investigated at Reynolds number of 14000. The Open Field Operations And Manipulations (OpenFOAM) computational fluid dynamic tool is used to solve flow governing equations numerically. The k-ω SST turbulence model with low Reynolds correction (k-ω SST LRC) and the pimpleDyMFOAM solver are utilized to simulate the flow field around pitching bio-airfoil. The lift and drag coefficients of the airfoil are calculated at reduced frequencies k=1.24-4.96 and the angular amplitude of A=5<sup>°</sup>-20<sup>°</sup>. Results show that in a fixed reduced frequency, the absolute value of the sectional lift and drag coefficients increase with increasing pitching amplitude. In a fixed angular amplitude, the absolute value of the lift and drag coefficients increase as the pitching reduced frequency increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-inspired%20pitching%20airfoils" title="bio-inspired pitching airfoils">bio-inspired pitching airfoils</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenFOAM" title=" OpenFOAM"> OpenFOAM</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20Reynolds%20k-%CF%89%20SST%20model" title=" low Reynolds k-ω SST model"> low Reynolds k-ω SST model</a>, <a href="https://publications.waset.org/abstracts/search?q=lift%20and%20drag%20coefficients" title=" lift and drag coefficients"> lift and drag coefficients</a> </p> <a href="https://publications.waset.org/abstracts/87363/aerodynamic-performance-of-a-pitching-bio-inspired-corrugated-airfoil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/87363.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">190</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">18</span> Different Methods Anthocyanins Extracted from Saffron</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hashem%20Barati">Hashem Barati</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshin%20Farahbakhsh"> Afshin Farahbakhsh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flowers of saffron contain anthocyanins. Generally, extraction of anthocyanins takes place at low temperatures (below 30 °C), preferably under vacuum (to minimize degradation) and in an acidic environment. In order to extract anthocyanins, the dried petals were added to 30 ml of acidic ethanol (pH=2). Amount of petals, extraction time, temperature, and ethanol percentage which were selected. Total anthocyanin content was a function of both variables of ethanol percent and extraction time.To prepare SW with pH of 3.5, different concentrations of 100, 400, 700, 1,000, and 2,000 ppm of sodium metabisulfite were added to aqueous sodium citrate. At this selected concentration, different extraction times of 20, 40, 60, 120, 180 min were tested to determine the optimum extraction time. When the extraction time was extended from 20 to 60 min, the total recovered anthocyanins of sulfur method changed from 650 to 710 mg/100 g. In the EW method Cellubrix and Pectinex enzymes were added separately to the buffer solution at different concentrations of 1%, 2.5%, 5%, 7%, 10%, and 12.5% and held for 2 hours reaction time at an ambient temperature of 40 °C. There was a considerable and significant difference in trends of Acys content of tepals extracted by pectinex enzymes at 5% concentration and AE solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saffron" title="saffron">saffron</a>, <a href="https://publications.waset.org/abstracts/search?q=anthocyanins" title=" anthocyanins"> anthocyanins</a>, <a href="https://publications.waset.org/abstracts/search?q=acidic%20environment" title=" acidic environment"> acidic environment</a>, <a href="https://publications.waset.org/abstracts/search?q=acidic%20ethanol" title=" acidic ethanol"> acidic ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=pectinex%20enzymes" title=" pectinex enzymes"> pectinex enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=Cellubrix%20enzymes" title=" Cellubrix enzymes"> Cellubrix enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20metabisulfite" title=" sodium metabisulfite"> sodium metabisulfite</a> </p> <a href="https://publications.waset.org/abstracts/48478/different-methods-anthocyanins-extracted-from-saffron" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48478.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">513</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">17</span> Life Course Events, Residential and Job Relocation and Commute Time in Australian Cities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solmaz%20Jahed%20Shiran">Solmaz Jahed Shiran</a>, <a href="https://publications.waset.org/abstracts/search?q=Elizabeth%20Taylor"> Elizabeth Taylor</a>, <a href="https://publications.waset.org/abstracts/search?q=John%20Hearne"> John Hearne</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Over the past decade a growing body of research, known as mobility biography approach has emerged that focuses on changes in travel behaviour over the life course of individuals. Mobility biographies suggest that changes in travel behaviour have a certain relation to important key events in life courses such as residential relocation, workplace changes, marriage and the birth of children. Taking this approach as the theoretical background, this study uses data from the Household, Income and Labor Dynamics Survey in Australia (HILDA) to model a set of life course events and their interaction with the commute time. By analysing longitudinal data, it is possible to assign different key events during the life course to change a person’s travel behaviour. Changes in the journey-to-work travel time is used as an indication of travel behaviour change in this study. Results of a linear regression model for change in commute time show a significant influence from socio-demographic factors like income and age, the previous home-to-work commute time and remoteness of the residence. Residential relocation and job change have significant influences on commute time. Other life events such as birth of a child, marriage and divorce or separation have also a strong impact on commute time change. Overall, the research confirms previous studies of links between life course events and travel behaviour. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=life%20course%20events" title="life course events">life course events</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20mobility" title=" residential mobility"> residential mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=travel%20behaviour" title=" travel behaviour"> travel behaviour</a>, <a href="https://publications.waset.org/abstracts/search?q=commute%20time" title=" commute time"> commute time</a>, <a href="https://publications.waset.org/abstracts/search?q=job%20change" title=" job change"> job change</a> </p> <a href="https://publications.waset.org/abstracts/103636/life-course-events-residential-and-job-relocation-and-commute-time-in-australian-cities" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103636.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">205</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">16</span> The Metacognition Levels of Students: A Research School of Physical Education and Sports at Anadolu University</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dilek%20Yal%C4%B1z%20Solmaz">Dilek Yalız Solmaz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Meta-cognition is an important factor for educating conscious individuals who are aware of their cognitive processes.

Method: For this purpose, in a descriptive-correlation study, 222 mothers and children aged 1 to 5 years in Tehran, who had the opportunity to answer an online questionnaire, were selected by random sampling and to the depression scales of the Kroenke and Spitzer Patient Health Questionnaire, Cohen's stress and Self-efficacy of Berkeley mothers answered. Pearson correlation test and path analysis were used for data analysis. Findings: The findings showed that maternal depression had an indirect and significant effect on child obesity, and the effect of stress and depression on child obesity was indirect and non-significant. Therefore, the model has a good fit with the research data, and stress and depression indirectly predicted child obesity with the mediating role of self-efficacy. Conclusion: The hypothesized model tested based on mother's stress and depression with the mediating role of mother's self-efficacy was a good model in explaining the prediction of child obesity. Based on the findings of this research, a practical framework can be provided to explain the psychological factors of the mother in relation to child obesity and its treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress" title="stress">stress</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20obesity" title=" child obesity"> child obesity</a>, <a href="https://publications.waset.org/abstracts/search?q=depression" title=" depression"> depression</a> </p> <a href="https://publications.waset.org/abstracts/181528/determining-the-relationship-between-maternal-stress-and-depression-and-child-obesity-the-mediating-role-of-maternal-self-efficacy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181528.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">71</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">14</span> Stabilization Control of the Nonlinear AIDS Model Based on the Theory of Polynomial Fuzzy Control Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahrokh%20Barati">Shahrokh Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we introduced AIDS disease at first, then proposed dynamic model illustrate its progress, after expression of a short history of nonlinear modeling by polynomial phasing systems, we considered the stability conditions of the systems, which contained a huge amount of researches in order to modeling and control of AIDS in dynamic nonlinear form, in this approach using a frame work of control any polynomial phasing modeling system which have been generalized by part of phasing model of T-S, in order to control the system in better way, the stability conditions were achieved based on polynomial functions, then we focused to design the appropriate controller, firstly we considered the equilibrium points of system and their conditions and in order to examine changes in the parameters, we presented polynomial phase model that was the generalized approach rather than previous Takagi Sugeno models, then with using case we evaluated the equations in both open loop and close loop and with helping the controlling feedback, the close loop equations of system were calculated, to simulate nonlinear model of AIDS disease, we used polynomial phasing controller output that was capable to make the parameters of a nonlinear system to follow a sustainable reference model properly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polynomial%20fuzzy" title="polynomial fuzzy">polynomial fuzzy</a>, <a href="https://publications.waset.org/abstracts/search?q=AIDS" title=" AIDS"> AIDS</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20AIDS%20model" title=" nonlinear AIDS model"> nonlinear AIDS model</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20control%20systems" title=" fuzzy control systems"> fuzzy control systems</a> </p> <a href="https://publications.waset.org/abstracts/36231/stabilization-control-of-the-nonlinear-aids-model-based-on-the-theory-of-polynomial-fuzzy-control-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36231.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">468</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">13</span> Fault Detection and Isolation in Sensors and Actuators of Wind Turbines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahrokh%20Barati">Shahrokh Barati</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ramezani"> Reza Ramezani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the countries growing attention to the renewable energy producing, the demand for energy from renewable energy has gone up among the renewable energy sources; wind energy is the fastest growth in recent years. In this regard, in order to increase the availability of wind turbines, using of Fault Detection and Isolation (FDI) system is necessary. Wind turbines include of various faults such as sensors fault, actuator faults, network connection fault, mechanical faults and faults in the generator subsystem. Although, sensors and actuators have a large number of faults in wind turbine but have discussed fewer in the literature. Therefore, in this work, we focus our attention to design a sensor and actuator fault detection and isolation algorithm and Fault-tolerant control systems (FTCS) for Wind Turbine. The aim of this research is to propose a comprehensive fault detection and isolation system for sensors and actuators of wind turbine based on data-driven approaches. To achieve this goal, the features of measurable signals in real wind turbine extract in any condition. The next step is the feature selection among the extract in any condition. The next step is the feature selection among the extracted features. Features are selected that led to maximum separation networks that implemented in parallel and results of classifiers fused together. In order to maximize the reliability of decision on fault, the property of fault repeatability is used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FDI" title="FDI">FDI</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20turbines" title=" wind turbines"> wind turbines</a>, <a href="https://publications.waset.org/abstracts/search?q=sensors%20and%20actuators%20faults" title=" sensors and actuators faults"> sensors and actuators faults</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20energy" title=" renewable energy"> renewable energy</a> </p> <a href="https://publications.waset.org/abstracts/39446/fault-detection-and-isolation-in-sensors-and-actuators-of-wind-turbines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39446.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">400</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">12</span> Identity Crisis and Class Difference in Charles Dickens' 'Great Expectations'</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramin%20Barati">Ramin Barati</a>, <a href="https://publications.waset.org/abstracts/search?q=Atefeh%20Salemi"> Atefeh Salemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Victorian era, the society had been surrounded by extreme class ranking in order to identify the people of the classes and to intensify power relationships due to the growth of industry in Charles Dickens's (1812-1870) Great Expectations (2003) in which he illustrates the clash and dichotomy in the 19th century London. The classes in Victorian period have socially divided the population into two parts, the lower and the upper class of the community. In such a panopticon society, the major character Pip was the best example of the working class who was under the domination of violence, malice, and abuse of Miss Havisham as a member of the ruling class in order to take revenge on her failures. The conflict and disunity represented in vindictiveness and the sense of revenge applied by Miss Havisham against his victim Pip, made him experience alienation and eventually suffer from identity crisis. This paper considers New Historicism based on the theories of the French critic Michel Foucault (1926-1984). The social concept, panopticism, was called after the panopticon society, basically elaborated by Foucault in his book Discipline and Punish (1975) and he considers the panopticon as a sign of punitive community of surveillance. This paper evaluates the problems of a dual society to show that the people of the lower class are under the domination of capitalist society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=class" title="class">class</a>, <a href="https://publications.waset.org/abstracts/search?q=identity%20crisis" title=" identity crisis"> identity crisis</a>, <a href="https://publications.waset.org/abstracts/search?q=violence" title=" violence"> violence</a>, <a href="https://publications.waset.org/abstracts/search?q=panoptic%20society" title=" panoptic society"> panoptic society</a>, <a href="https://publications.waset.org/abstracts/search?q=domination" title=" domination"> domination</a> </p> <a href="https://publications.waset.org/abstracts/97813/identity-crisis-and-class-difference-in-charles-dickens-great-expectations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97813.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">239</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">11</span> Development of Mineral Carbonation Process from Ultramafic Tailings, Enhancing the Reactivity of Feedstocks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Gardideh">Sara Gardideh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansoor%20Barati"> Mansoor Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mineral carbonation approach for reducing global warming has garnered interest on a worldwide scale. Due to the benefits of permanent storage and abundant mineral resources, mineral carbonation (MC) is one of the most effective strategies for sequestering CO₂. The combination of mineral processing for primary metal recovery and mineral carbonation for carbon sequestration is an emerging field of study with the potential to minimize capital costs. A detailed study of low-pressures–solid carbonation of ultramafic tailings in a dry environment has been accomplished. In order to track the changing structure of serpentine minerals and their reactivity as a function of temperature (300-900 ᵒC), CO₂ partial pressure (25-90 mol %), and thermal preconditioning, thermogravimetry has been utilized. The incongruent CO₂ van der Waals molecular diameters with the octahedral-tetrahedral lattice constants of serpentine were used to explain the mild carbonation reactivity. Serpentine requires additional thermal-treatment to remove hydroxyl groups, resulting in the chemical transformation to pseudo-forsterite, which is a mineral composed of isolated SiO₄ tetrahedra linked by octahedrally coordinated magnesium ions. The heating treatment above 850 ᵒC is adequate to remove chemically bound water from the lattice. Particles with a diameter < 34 (μm) are desirable, and thermally treated serpentine at 850 ᵒC for 2.30 hours reached 65% CO₂ storage capacity. The decrease in particle size, increase in temperature, and magnetic separation can dramatically enhance carbonation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20size" title="particle size">particle size</a>, <a href="https://publications.waset.org/abstracts/search?q=thermogravimetry" title=" thermogravimetry"> thermogravimetry</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal-treatment" title=" thermal-treatment"> thermal-treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=serpentine" title=" serpentine"> serpentine</a> </p> <a href="https://publications.waset.org/abstracts/162718/development-of-mineral-carbonation-process-from-ultramafic-tailings-enhancing-the-reactivity-of-feedstocks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162718.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">10</span> Evaluating News in Press about Konya in Context of City Image</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nur%20Gorkemli">Nur Gorkemli</a>, <a href="https://publications.waset.org/abstracts/search?q=Basak%20Solmaz"> Basak Solmaz </a> </p> <p class="card-text"><strong>Abstract:</strong></p> With globalization, competition between cities increased and therefore cities started to give more importance to be a more differentiated one among thousands of their competitors. In order to become a more livable place and appeal more tourists, more investors, more students and more people cities give importance to marketing and branding activities. City image is very important concept for building a city brand. Cinemas, books, news or information about cities create 'city image' in peoples’ minds. Every city has their own peculiarities and changing their neutral or negative image to a positive way will bring advantages to them in national and even in international arena. Konya, which is a city in central Anatolia, has been an important city since very early times in human kind. It has the ruins of one of the first settlements existed approximately 9.000 years ago. Moreover, it was the capital of Selcuk Empire before Ottoman period and also a very important city during Ottoman Empire. With this historical richness, the city has important structures and works of art from those periods. Moreover, the city is also very well-known in the world with one of the greatest philosopher, poet, theologian, and Sufi mystic Mevlana Jelaleddin Rumi, who lived most of his life in Konya. Every year nearly two million people from various cities and countries visit Mevlana Museum. With all these potentials, Turkish Ministry of Culture and Tourism chose Konya to be a branded city in its 2023 action plan. For branding activities, understanding city image has a crucial role. Moreover, news about cities has a great potential on building a 'city image' in minds. This study is aimed at interpreting Konya’s image by categorizing Konya’s news existed in three national newspapers, which has the highest circulation in Turkey.

Hence a change in those locations due to a move or changes in an occupation leads to a change in travel behavior. Given the interventions of housing mobility and travel behaviors, the hypothesis is that a mobile housing market allows households to move as a result of any change in their life course, allowing them to be closer to central services, public transport facilities and workplace and hence reducing the time spent by individuals on daily travel. Conversely, household’s immobility may lead to longer commutes of residents, for example, after a change of a job or a need for new services such as schools for children who have reached their school age. This paper aims to investigate the association between residential mobility and travel behavior. The Victorian Integrated Survey of Travel and Activity (VISTA) data is used for the empirical analysis. Car ownership and journey to work time and distance of employed people are used as indicators of travel behavior. Change of usual residence within the last five years used to identify movers and non-movers. Statistical analysis, including regression models, is used to compare the travel behavior of movers and non-movers. The results show travel time, and the distance does not differ for movers and non-movers. However, this is not the case when taking into account the residence tenure-type. In addition, car ownership rate and number found to be significantly higher for non-movers. It is hoped that the results from this study will contribute to a better understanding of factors other than common socioeconomic and built environment features influencing travel behavior. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=journey%20to%20work" title="journey to work">journey to work</a>, <a href="https://publications.waset.org/abstracts/search?q=regression%20models" title=" regression models"> regression models</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20mobility" title=" residential mobility"> residential mobility</a>, <a href="https://publications.waset.org/abstracts/search?q=commute%20mode" title=" commute mode"> commute mode</a>, <a href="https://publications.waset.org/abstracts/search?q=car%20ownership" title=" car ownership"> car ownership</a> </p> <a href="https://publications.waset.org/abstracts/110682/interactions-between-residential-mobility-car-ownership-and-commute-mode-the-case-for-melbourne" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/110682.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">133</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">8</span> Evaluation the Concentration of Pb, Cd, Cu, Ni, Zn, Cr in Rainbow Trout and Water of Haraz River</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Tehranisharif">Meysam Tehranisharif</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Nakhaee"> Hadi Nakhaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Aaghaali%20Seyed%20Moosavi"> Seyed Aaghaali Seyed Moosavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Solmaz%20Ahadi"> Solmaz Ahadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Being the second largest river in the southern Caspian Sea basin, the Haraz River ﬂows northwards through the Alborz mountains in the central region of Mazandaran province.The Haraz basin has speciﬁc geological characteristics affecting the river water quality.This area has been a rich source of minerals from times immemorial.

The fault occurs in any system components such as actuators, sensors or internal structure of the system and leads to loss of performance and instability of the system. When a fault occurs, the purpose of the fault-tolerant control is designate strategy that can keep the control loop stable and system performance as much as possible perform it without shutting down the system. Here, the section of fault detection and isolation (FDI) system has been evaluated with regard to actuator's fault. Designing a fault detection and isolation system for a multi input-multi output (MIMO) is done by an unknown input observer, so the system is divided to several subsystems as the effect of other inputs such as disturbing given system state equations. In this observer design method, the effect of these disturbances will weaken and the only fault is detected on specific input. The results of this approach simulation can confirm the ability of the fault detection and isolation system design. After fault detection and isolation, it is necessary to redesign controller based on a suitable modification. In this regard after the use of unknown input observer theory and obtain residual signal and evaluate it, PID controller parameters redesigned for iterative. Stability of the closed loop system has proved in the presence of this method. Also, In order to soften the volatility caused by Annie variations of the PID controller parameters, modifying Sigma as a way acceptable solution used. Finally, the simulation results of three tank popular example confirm the accuracy of performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fault%20tolerant%20control" title="fault tolerant control">fault tolerant control</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20detection%20and%20isolation" title=" fault detection and isolation"> fault detection and isolation</a>, <a href="https://publications.waset.org/abstracts/search?q=actuator%20fault" title=" actuator fault"> actuator fault</a>, <a href="https://publications.waset.org/abstracts/search?q=unknown%20input%20observer" title=" unknown input observer"> unknown input observer</a> </p> <a href="https://publications.waset.org/abstracts/36532/fault-tolerant-control-of-the-dynamical-systems-based-on-internal-structure-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36532.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">452</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">6</span> The Effects of Pilates and McKenzie Exercises on Quality of Life and Lumbar Spine Position Sense in Patients with Low Back Pain: A Comparative Study with a 4-Week Follow-Up</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vahid%20Mazloum">Vahid Mazloum</a>, <a href="https://publications.waset.org/abstracts/search?q=Mansour%20Sahebozamani"> Mansour Sahebozamani</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirhossein%20Barati"> Amirhossein Barati</a>, <a href="https://publications.waset.org/abstracts/search?q=Nouzar%20Nakhaee"> Nouzar Nakhaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Pouya%20Rabiei"> Pouya Rabiei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Non-specific chronic low back pain (NSCLBP) is a common condition with no exact diagnosis and mechanism for its occurrence. Recently, different therapeutic exercises have taken into account to manage NSCLBP. So, the aim of this study has mainly been placed on comparing the effects of Pilates and Mackenzie exercises on quality of life (QOL) lumbar spine position sense (LSPS) in patients with NSCLBP. In this randomized clinical trial, 47 patients with NSCLBP were voluntarily divided into three groups of Pilates (n=16) (with mean age 37.1 ± 9.5 years, height 168.9 ± 7.4 cm, body mass 76.1 ± 5.9 k), McKenzie (n=15) (with mean age 42.7 ± 8.1 years, height 165.7 ± 6.8, body mass 74.1 ± 4.8 kg) and control (n=16) (with mean age 39.3 ± 9.8 years, height 168.1 ± 8.1 cm, body mass 74.2 ± 5.8 kg). Primary outcome included QOL and secondary was LSPS. Both variables were assessed by the WHOQOL-BREF questionnaires and electrogoniameter, respectively. The measurements were performed at baseline, following a 6-week intervention, and after a 4-week follow-up. The ANCOVA test at P < 0.05 was administrated to analyze the collected data using SPSS software. There was a statistically significant difference between experimental groups and the control group to improve QOL. But, no difference was seen regarding the effects of two exercises on LSPS (p < 0.05). Both Pilates and Mackenzie exercises demonstrated improvement in QOL after 6-week intervention and a 4-week follow-up while none of them considerably affected LSPS. Further studies are required to establish a supporting evidence for the effectiveness of two exercises on NSCLBP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pilates" title="pilates">pilates</a>, <a href="https://publications.waset.org/abstracts/search?q=Mackenzie" title=" Mackenzie"> Mackenzie</a>, <a href="https://publications.waset.org/abstracts/search?q=preconception" title=" preconception"> preconception</a>, <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=physical%20health" title=" physical health"> physical health</a> </p> <a href="https://publications.waset.org/abstracts/76617/the-effects-of-pilates-and-mckenzie-exercises-on-quality-of-life-and-lumbar-spine-position-sense-in-patients-with-low-back-pain-a-comparative-study-with-a-4-week-follow-up" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76617.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">190</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">5</span> Development of an Implicit Physical Influence Upwind Scheme for Cell-Centered Finite Volume Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour">Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mohammadi"> Masoud Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouzbeh%20Riazi"> Rouzbeh Riazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Ormiston"> Scott Ormiston</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimia%20Amiri"> Kimia Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Barati"> Sahar Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An essential component of a finite volume method (FVM) is the advection scheme that estimates values on the cell faces based on the calculated values on the nodes or cell centers. The most widely used advection schemes are upwind schemes. These schemes have been developed in FVM on different kinds of structured and unstructured grids. In this research, the physical influence scheme (PIS) is developed for a cell-centered FVM that uses an implicit coupled solver. Results are compared with the exponential differencing scheme (EDS) and the skew upwind differencing scheme (SUDS). Accuracy of these schemes is evaluated for a lid-driven cavity flow at Re = 1000, 3200, and 5000 and a backward-facing step flow at Re = 800. Simulations show considerable differences between the results of EDS scheme with benchmarks, especially for the lid-driven cavity flow at high Reynolds numbers. These differences occur due to false diffusion. Comparing SUDS and PIS schemes shows relatively close results for the backward-facing step flow and different results in lid-driven cavity flow. The poor results of SUDS in the lid-driven cavity flow can be related to its lack of sensitivity to the pressure difference between cell face and upwind points, which is critical for the prediction of such vortex dominant flows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cell-centered%20finite%20volume%20method" title="cell-centered finite volume method">cell-centered finite volume method</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20solver" title=" coupled solver"> coupled solver</a>, <a href="https://publications.waset.org/abstracts/search?q=exponential%20differencing%20scheme%20%28EDS%29" title=" exponential differencing scheme (EDS)"> exponential differencing scheme (EDS)</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20influence%20scheme%20%28PIS%29" title=" physical influence scheme (PIS)"> physical influence scheme (PIS)</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20weighted%20interpolation%20method%20%28PWIM%29" title=" pressure weighted interpolation method (PWIM)"> pressure weighted interpolation method (PWIM)</a>, <a href="https://publications.waset.org/abstracts/search?q=skew%20upwind%20differencing%20scheme%20%28SUDS%29" title=" skew upwind differencing scheme (SUDS)"> skew upwind differencing scheme (SUDS)</a> </p> <a href="https://publications.waset.org/abstracts/65764/development-of-an-implicit-physical-influence-upwind-scheme-for-cell-centered-finite-volume-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65764.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">284</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">4</span> A Two-Phase Flow Interface Tracking Algorithm Using a Fully Coupled Pressure-Based Finite Volume Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour">Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Scott%20Ormiston"> Scott Ormiston</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mohammadi"> Masoud Mohammadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rouzbeh%20Riazi"> Rouzbeh Riazi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimia%20Amiri"> Kimia Amiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Barati"> Sahar Barati</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two-phase and multi-phase flows are common flow types in fluid mechanics engineering. Among the basic and applied problems of these flow types, two-phase parallel flow is the one that two immiscible fluids flow in the vicinity of each other. In this type of flow, fluid properties (e.g. density, viscosity, and temperature) are different at the two sides of the interface of the two fluids. The most challenging part of the numerical simulation of two-phase flow is to determine the location of interface accurately. In the present work, a coupled interface tracking algorithm is developed based on Arbitrary Lagrangian-Eulerian (ALE) approach using a cell-centered, pressure-based, coupled solver. To validate this algorithm, an analytical solution for fully developed two-phase flow in presence of gravity is derived, and then, the results of the numerical simulation of this flow are compared with analytical solution at various flow conditions. The results of the simulations show good accuracy of the algorithm despite using a nearly coarse and uniform grid. Temporal variations of interface profile toward the steady-state solution show that a greater difference between fluids properties (especially dynamic viscosity) will result in larger traveling waves. Gravity effect studies also show that favorable gravity will result in a reduction of heavier fluid thickness and adverse gravity leads to increasing it with respect to the zero gravity condition. However, the magnitude of variation in favorable gravity is much more than adverse gravity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coupled%20solver" title="coupled solver">coupled solver</a>, <a href="https://publications.waset.org/abstracts/search?q=gravitational%20force" title=" gravitational force"> gravitational force</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20tracking" title=" interface tracking"> interface tracking</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynolds%20number%20to%20Froude%20number" title=" Reynolds number to Froude number"> Reynolds number to Froude number</a>, <a href="https://publications.waset.org/abstracts/search?q=two-phase%20flow" title=" two-phase flow"> two-phase flow</a> </p> <a href="https://publications.waset.org/abstracts/72267/a-two-phase-flow-interface-tracking-algorithm-using-a-fully-coupled-pressure-based-finite-volume-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72267.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">315</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">3</span> Evaluation of Mechanical Properties and Surface Roughness of Nanofilled and Microhybrid Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Solmaz%20Eskandarion">Solmaz Eskandarion</a>, <a href="https://publications.waset.org/abstracts/search?q=Haniyeh%20Eftekhar"> Haniyeh Eftekhar</a>, <a href="https://publications.waset.org/abstracts/search?q=Amin%20Fallahi"> Amin Fallahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Nowadays cosmetic dentistry has gained greater attention because of the changing demands of dentistry patients. Composite resin restorations play an important role in the field of esthetic restorations. Due to the variation between the resin composites, it is important to be aware of their mechanical properties and surface roughness. So, the aim of this study was to compare the mechanical properties (surface hardness, compressive strength, diametral tensile strength) and surface roughness of four kinds of resin composites after thermal aging process. Materials and Method: 10 samples of each composite resins (Gradia-direct (GC), Filtek Z250 (3M), G-ænial (GC), Filtek Z350 (3M- filtek supreme) prepared for evaluation of each properties (totally 120 samples). Thermocycling (with temperature 5 and 55 degree of centigrade and 10000 cycles) were applied. Then, the samples were tested about their compressive strength and diametral tensile strength using UTM. And surface hardness was evaluated with Microhardness testing machine. Either surface roughness was evaluated with Scanning electron microscope after surface polishing. Result: About compressive strength (CS), Filtek Z250 showed the highest value. But there were not any significant differences between 4 groups about CS. Either Filtek Z250 detected as a composite with highest value of diametral tensile strength (DTS) and after that highest to lowest DTS was related to: Filtek Z350, G-ænial and Gradia-direct. And about DTS all of the groups showed significant differences (P<0.05). Vickers Hardness Number (VHN) of Filtek Z250 was the greatest. After that Filtek Z350, G-ænial and Gradia-direct followed it. The surface roughness of nano-filled composites was less than Microhybrid composites. Either the surface roughness of GC Ganial was a little greater than Filtek Z250. Conclusion: This study indicates that there is not any evident significant difference between the groups amoung their mechanical properties. But it seems that Filtek Z250 showed slightly better mechanical properties. About surface roughness, nanofilled composites were better that Microhybrid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title="mechanical properties">mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20roughness" title=" surface roughness"> surface roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=resin%20composite" title=" resin composite"> resin composite</a>, <a href="https://publications.waset.org/abstracts/search?q=compressive%20strength" title=" compressive strength"> compressive strength</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20aging" title=" thermal aging"> thermal aging</a> </p> <a href="https://publications.waset.org/abstracts/16356/evaluation-of-mechanical-properties-and-surface-roughness-of-nanofilled-and-microhybrid-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16356.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">354</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">2</span> Multiphase Flow Regime Detection Algorithm for Gas-Liquid Interface Using Ultrasonic Pulse-Echo Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Serkan%20Solmaz">Serkan Solmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Baptiste%20Gouriet"> Jean-Baptiste Gouriet</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Van%20de%20Wyer"> Nicolas Van de Wyer</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Schram"> Christophe Schram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Efficiency of the cooling process for cryogenic propellant boiling in engine cooling channels on space applications is relentlessly affected by the phase change occurs during the boiling. The effectiveness of the cooling process strongly pertains to the type of the boiling regime such as nucleate and film. Geometric constraints like a non-transparent cooling channel unable to use any of visualization methods. The ultrasonic (US) technique as a non-destructive method (NDT) has therefore been applied almost in every engineering field for different purposes. Basically, the discontinuities emerge between mediums like boundaries among different phases. The sound wave emitted by the US transducer is both transmitted and reflected through a gas-liquid interface which makes able to detect different phases. Due to the thermal and structural concerns, it is impractical to sustain a direct contact between the US transducer and working fluid. Hence the transducer should be located outside of the cooling channel which results in additional interfaces and creates ambiguities on the applicability of the present method. In this work, an exploratory research is prompted so as to determine detection ability and applicability of the US technique on the cryogenic boiling process for a cooling cycle where the US transducer is taken place outside of the channel. Boiling of the cryogenics is a complex phenomenon which mainly brings several hindrances for experimental protocol because of thermal properties. Thus substitute materials are purposefully selected based on such parameters to simplify experiments. Aside from that, nucleate and film boiling regimes emerging during the boiling process are simply simulated using non-deformable stainless steel balls, air-bubble injection apparatuses and air clearances instead of conducting a real-time boiling process. A versatile detection algorithm is perennially developed concerning exploratory studies afterward. According to the algorithm developed, the phases can be distinguished 99% as no-phase, air-bubble, and air-film presences. The results show the detection ability and applicability of the US technique for an exploratory purpose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ultrasound" title="Ultrasound">Ultrasound</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrasonic" title=" ultrasonic"> ultrasonic</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=boiling" title=" boiling"> boiling</a>, <a href="https://publications.waset.org/abstracts/search?q=cryogenics" title=" cryogenics"> cryogenics</a>, <a href="https://publications.waset.org/abstracts/search?q=detection%20algorithm" title=" detection algorithm"> detection algorithm</a> </p> <a href="https://publications.waset.org/abstracts/98507/multiphase-flow-regime-detection-algorithm-for-gas-liquid-interface-using-ultrasonic-pulse-echo-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98507.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">170</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">1</span> Simulation of Hydraulic Fracturing Fluid Cleanup for Partially Degraded Fracturing Fluids in Unconventional Gas Reservoirs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Regina%20A.%20Tayong">Regina A.

This model has been validated as against field data reported in the literature for the same reservoir. A 2-D, two-phase (gas/water) fracture propagation model is used to model our invasion zone and create the initial conditions for our clean-up model by distributing 200 bbls of water around the fracture. A 2-D, three-phase IMPES simulator, incorporating a yield-power-law-rheology has been developed in MATLAB to characterize fluid flow through a hydraulically fractured grid. The variation in polymer concentration along the fracture is computed from a material balance equation relating the initial polymer concentration to total volume of injected fluid and fracture volume. All governing equations and the methods employed have been adequately reported to permit easy replication of results. The effect of increasing capillary pressure in the formation simulated in this study resulted in a 10.4% decrease in cumulative production after 100 days of fluid recovery. Increasing the breaker concentration from 5-15 gal/Mgal on the yield stress and fluid viscosity of a 200 lb/Mgal guar fluid resulted in a 10.83% increase in cumulative gas production. For tight gas formations (k=0.05 md), fluid recovery increases with increasing shut-in time, increasing fracture conductivity and fracture length, irrespective of the yield stress of the fracturing fluid. Mechanical induced formation damage combined with hydraulic damage tends to be the most significant. Several correlations have been developed relating pressure distribution and polymer concentration to distance along the fracture face and average polymer concentration variation with injection time. The gradient in yield stress distribution along the fracture face becomes steeper with increasing polymer concentration. The rate at which the yield stress (τ_o) is increasing is found to be proportional to the square of the volume of fluid lost to the formation. Finally, an improvement on previous results was achieved through simulating yield stress variation along the fracture face rather than assuming constant values because fluid loss to the formation and the polymer concentration distribution along the fracture face decreases as we move away from the injection well. The novelty of this three-phase flow model lies in its ability to (i) Simulate yield stress variation with fluid loss volume along the fracture face for different initial guar concentrations. (ii) Simulate increasing breaker activity on yield stress and broken gel viscosity and the effect of (i) and (ii) on cumulative gas production within reasonable computational time. <p
