It mainly discusses code-switching and usage of Persian words in the novel. Hosseini mainly writes in English; however, constantly he applies Persian words, phrases and syntax. Code-switching is used for different purposes in A Thousand Splendid Suns. It gives a voice to a character from Afghanistan. It is also used to mark a difference between the American and Afghanistan cultures and languages. Furthermore, representation of Persian language can be interpreted as valorization of the author’s mother tongue. In short, the writing style in A Thousand Splendid Suns represents Hosseini’s identity, culture and linguistic background. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=code-switching" title="code-switching">code-switching</a>, <a href="https://publications.waset.org/abstracts/search?q=hybridity" title=" hybridity"> hybridity</a>, <a href="https://publications.waset.org/abstracts/search?q=identity" title=" identity"> identity</a>, <a href="https://publications.waset.org/abstracts/search?q=linguistic%20background" title=" linguistic background"> linguistic background</a>, <a href="https://publications.waset.org/abstracts/search?q=Persian%20literature" title=" Persian literature"> Persian literature</a> </p> <a href="https://publications.waset.org/abstracts/156374/writing-style-in-a-thousand-splendid-suns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156374.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">97</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">112</span> Formulating the Stochastic Finite Elements for Free Vibration Analysis of Plates with Variable Elastic Modulus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Aghamiri%20Esfahani">Mojtaba Aghamiri Esfahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Karkon"> Mohammad Karkon</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Majid%20Hosseini%20Nezhad"> Seyed Majid Hosseini Nezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Hosseini-Ara"> Reza Hosseini-Ara </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the effect of uncertainty in elastic modulus of a plate on free vibration response is investigated. For this purpose, the elastic modulus of the plate is modeled as stochastic variable with normal distribution. Moreover, the distance autocorrelation function is used for stochastic field. Then, by applying the finite element method and Monte Carlo simulation, stochastic finite element relations are extracted. Finally, with a numerical test, the effect of uncertainty in the elastic modulus on free vibration response of a plate is studied. The results show that the effect of uncertainty in elastic modulus of the plate cannot play an important role on the free vibration response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stochastic%20finite%20elements" title="stochastic finite elements">stochastic finite elements</a>, <a href="https://publications.waset.org/abstracts/search?q=plate%20bending" title=" plate bending"> plate bending</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title=" free vibration"> free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=Monte%20Carlo" title=" Monte Carlo"> Monte Carlo</a>, <a href="https://publications.waset.org/abstracts/search?q=Neumann%20expansion%20method." title=" Neumann expansion method.

There are different methods that can be used to remove these contaminants from water and soil. These are very expensive and time-consuming. In this case, the people have been forced to leave the area and the decontamination is not done. For example, in the case of Chernobyl accident, an area of 30 km around the plant was emptied of human life. A very efficient and cost-effective method for decontamination of the soil and the water is phytoremediation. In this method, the plants preferentially native plants which are more adaptive to the regional climate are well used. In this study, three types of plants including Alfalfa, Sunflower and wheat were used to Barium decontamination. Alfalfa and Sunflower were not grown good enough in Saghand mine’s soil sample. This can be due to non-native origin of these plants. But, Wheat rise in Saghand Uranium Mine soil sample was satisfactory. In this study, we have investigated the effect of 4 types of acids inclusive nitric acid, oxalic acid, acetic acid and citric acid on the removal efficiency of Barium by Wheat. Our results indicate the increase of Barium absorption in the presence of citric acid in the soil. In this paper, we will present our research and laboratory results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phytoremediation" title="phytoremediation">phytoremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metal" title=" heavy metal"> heavy metal</a>, <a href="https://publications.waset.org/abstracts/search?q=wheat" title=" wheat"> wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil "> soil </a> </p> <a href="https://publications.waset.org/abstracts/21388/the-effect-of-additive-acid-on-the-phytoremediation-efficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21388.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">337</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">110</span> A Conceptual Study for Investigating the Preliminary State of Energy at the Birth of Universe and Understanding Its Emergence From the State of Nothing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Reza%20Hosseini">Mahmoud Reza Hosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a comprehensive energy model is proposed and utilized to study the birth of universe from the state of nothing.

In order to quantify this phenomenon in different leaves and investigate the influence of leaf shape on heat transfer, natural convection for pine, orange and olive leaves was simulated as representatives of different groups of leaf shapes. CFD techniques were used in this simulation with the purpose to calculate heat transfer of leaves in similar environmental conditions. The problem was simulated for steady state and three-dimensional conditions. From obtained results, it was concluded that heat fluxes of all three different leaves are almost identical, however, total rate of heat transfer have highest and lowest values for orange leaves and pine leaves, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamic" title="computational fluid dynamic">computational fluid dynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20flux" title=" heat flux"> heat flux</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a> </p> <a href="https://publications.waset.org/abstracts/30133/numerical-investigation-of-natural-convection-of-pine-olive-and-orange-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30133.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">361</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">99</span> Simulation and Study of the Effect of Paint Mineral Coating on Energy Saving </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20A.%20Azemati">A.

In the present study, a green method was presented to synthesis silver-phosphate nanoparticles using <em>Sporosarcina pasteurii</em>. The composition of the biosynthesized nanoparticles was identified as Ag<sub>3</sub>PO<sub>4</sub> using X-ray Diffraction (XRD) and Energy Dispersive Spectroscopy (EDS). Also, Fourier Transform Infrared (FTIR) spectroscopy showed that Ag<sub>3</sub>PO<sub>4</sub> nanoparticles was synthesized in the presence of biosurfactants, enzymes, and proteins. In addition, UV-Vis adsorption of the produced colloidal suspension approved the results of XRD and FTIR analyses. Finally, Transmission Electron Microscope (TEM) images indicated that the size of the nanoparticles was about 20 nm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bacteria" title="bacteria">bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=biosynthesis" title=" biosynthesis"> biosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=silver-phosphate" title=" silver-phosphate"> silver-phosphate</a>, <a href="https://publications.waset.org/abstracts/search?q=Sporosarcina%20pasteurii" title=" Sporosarcina pasteurii"> Sporosarcina pasteurii</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticle" title=" nanoparticle"> nanoparticle</a> </p> <a href="https://publications.waset.org/abstracts/57439/biosynthesis-of-silver-phosphate-nanoparticles-using-the-extracellular-polymeric-substance-of-sporosarcina-pasteurii" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57439.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">449</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">94</span> Customers’ Priority to Implement SSTs Using AHP Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Jafariahangari">Mohammad Jafariahangari</a>, <a href="https://publications.waset.org/abstracts/search?q=Marjan%20Habibi"> Marjan Habibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Miresmaeil%20Mirnabibaboli"> Miresmaeil Mirnabibaboli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mirza%20Hassan%20Hosseini"> Mirza Hassan Hosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Self-service technologies (SSTs) make an important contribution to the daily life of people nowadays. However, the introduction of SST does not lead to its usage. Thereby, this paper was an attempt on discovery of the most preferred SST in the customers’ point of view. To fulfill this aim, the Analytical Hierarchy Process (AHP) was applied based on Saaty’s questionnaire which was administered to the customers of e-banking services located in Golestan providence, north of Iran. This study used qualitative factors in association with the intention of consumers’ usage of SSTs to rank three SSTs: ATM, mobile banking, and internet banking. The results showed that mobile banking get the highest weight in consumers’ point of view. This research can be useful both for managers and service providers and also for customers who intend to use e-banking. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20hierarchy%20process" title="analytical hierarchy process">analytical hierarchy process</a>, <a href="https://publications.waset.org/abstracts/search?q=decision-making" title=" decision-making"> decision-making</a>, <a href="https://publications.waset.org/abstracts/search?q=e-banking" title=" e-banking"> e-banking</a>, <a href="https://publications.waset.org/abstracts/search?q=self-service%20technologies" title=" self-service technologies"> self-service technologies</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/15518/customers-priority-to-implement-ssts-using-ahp-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15518.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">318</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">93</span> A Green Method for Selective Spectrophotometric Determination of Hafnium(IV) with Aqueous Extract of Ficus carica Tree Leaves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Boveiri%20Monji">A.

In 6-M hydrochloric acid, hafnium reacts with this reagent to form a yellow product. The formed product shows maximum absorbance at 421 nm with a molar absorptivity value of 0.28 × 104 l mol⁻¹ cm⁻¹, and the method was linear in the 2-11 µg ml⁻¹ concentration range. The detection limit value was found to be 0.312 µg ml⁻¹. Except zirconium and iron, the selectivity was good, and most of the ions did not show any significant spectral interference at concentrations up to several hundred times. The proposed method was green, simple, low cost, and selective. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spectrophotometric%20determination" title="spectrophotometric determination">spectrophotometric determination</a>, <a href="https://publications.waset.org/abstracts/search?q=Ficus%20caricatree%20leaves" title=" Ficus caricatree leaves"> Ficus caricatree leaves</a>, <a href="https://publications.waset.org/abstracts/search?q=synthetic%20reagents" title=" synthetic reagents"> synthetic reagents</a>, <a href="https://publications.waset.org/abstracts/search?q=hafnium" title=" hafnium"> hafnium</a> </p> <a href="https://publications.waset.org/abstracts/88855/a-green-method-for-selective-spectrophotometric-determination-of-hafniumiv-with-aqueous-extract-of-ficus-carica-tree-leaves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88855.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">92</span> Development of a New Polymeric Material with Controlled Surface Micro-Morphology Aimed for Biosensors Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Farahmand">Elham Farahmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatimah%20Ibrahim"> Fatimah Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Hosseini"> Samira Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Djordjevic"> Ivan Djordjevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Leo.%20H.%20Koole"> Leo.

Polymer coated surfaces have been produced on silicon wafers. Coated samples were analyzed by atomic force microscopy (AFM). The results have shown that the roughness of the surfaces have increased by increasing the molar ratio of monomer methacrylic acid (MAA). This study reveals that the gradual increase in surface roughness is due to the fact that carboxylic functional groups have been generated by MAA segments. Such surfaces can be desirable platforms for fabrication of the biosensors for detection of the viruses and diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polymethylmethacrylate-co-methacrylic%20acid%20%28PMMA-co-MAA%29" title="polymethylmethacrylate-co-methacrylic acid (PMMA-co-MAA)">polymethylmethacrylate-co-methacrylic acid (PMMA-co-MAA)</a>, <a href="https://publications.waset.org/abstracts/search?q=polymeric%20material" title=" polymeric material"> polymeric material</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20force%20microscopy" title=" atomic force microscopy"> atomic force microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=roughness" title=" roughness"> roughness</a>, <a href="https://publications.waset.org/abstracts/search?q=carboxylic%20functional%20groups" title=" carboxylic functional groups"> carboxylic functional groups</a> </p> <a href="https://publications.waset.org/abstracts/17120/development-of-a-new-polymeric-material-with-controlled-surface-micro-morphology-aimed-for-biosensors-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17120.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">595</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">91</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.

So, in most of the countries, different parts of electrical industry like generation, transmission, and distribution have been separated in order to create competition. Considering these changes, environmental issues, energy growth, investment of private equity in energy generation units and difficulties of transmission lines expansion, distributed generation (DG) units have been used in power systems. Moreover, reduction in the need for transmission and distribution, the increase of reliability, improvement of power quality, and reduction of power loss have caused DG to be placed in power systems. On the other hand, considering low liquidity need, private investors tend to spend their money for DGs. In this project, the main goal is to offer an algorithm for planning and placing DGs in order to reduce the need for transmission and distribution network. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=planning" title="planning">planning</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission" title=" transmission"> transmission</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20security" title=" power security"> power security</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20systems" title=" power systems"> power systems</a> </p> <a href="https://publications.waset.org/abstracts/68494/composite-distributed-generation-and-transmission-expansion-planning-considering-security" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68494.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">480</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">87</span> Benefits of Therapeutic Climbing on Multiple Components of Attention in Attention Deficit Hyperactivity Disorder Children</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elaheh%20Hosseini">Elaheh Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Otmar%20Bock"> Otmar Bock</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Thomas"> Monika Thomas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of the present study was to determine the effect of climbing therapy on the components of attention of children with attention-deficit hyperactivity disorder (ADHD). Forty children with ADHD were assigned to either an intervention group or a control group.

All two groups were then assessed with the same battery of attention tests used in our earlier study. We found that compared to the ‘intervention’ group, performance was higher in the ‘control’ group on tests of sustained, divided and distributed attention, on all four tests.

Hydrodynamic lubrication (HL), mixed lubrication (ML), and boundary lubrication (BL) are three regimes of a journal bearing lubrication. This paper uses acoustic emission (AE) measurement technique to correlate features of the AE signals to the three lubrication regimes. The transitions from HL to ML based on operating factors such as rotating speed, load, inlet oil pressure by time domain and time-frequency domain signal analysis techniques are detected, and then metal-to-metal contacts between sliding surfaces of the journal and bearing are identified. It is found that there is a significant difference between theoretical and experimental operating values that are obtained for defining the lubrication regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acoustic%20emission%20technique" title="acoustic emission technique">acoustic emission technique</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20fed%20journal%20bearing" title=" pressure fed journal bearing"> pressure fed journal bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20and%20frequency%20signal%20analysis" title=" time and frequency signal analysis"> time and frequency signal analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=metal-to-metal%20contact" title=" metal-to-metal contact"> metal-to-metal contact</a> </p> <a href="https://publications.waset.org/abstracts/101940/the-lubrication-regimes-recognition-of-a-pressure-fed-journal-bearing-by-time-and-frequency-domain-analysis-of-acoustic-emission-signals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101940.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">155</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">85</span> Numerical Investigation of the Effect of Number of Waves on Heat Transfer in a Wavy Wall Enclosure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Tahavvor">Ali Reza Tahavvor</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Hosseini"> Saeed Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshin%20Karimzadeh%20Fard"> Afshin Karimzadeh Fard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the effect of wall waviness of side walls in a two-dimensional wavy enclosure is numerically investigated. Two vertical wavy walls and straight top wall are kept isothermal and the bottom wall temperature is higher and spatially varying with cosinusoidal temperature distribution. A computational code based on Finite-volume approach is used to solve governing equations and SIMPLE method is used for pressure velocity coupling. Test is performed for several different numbers of undulations. The Prandtl number was kept constant and the Ra number denotes that the flow is laminar. Temperature and velocity fields are determined. Therefore, according to the obtained results a correlation is proposed for average Nusselt number as a function of number of side wall waves. The results indicate that the Nusselt number is highly affected by number of waves and increasing it decreases the wavy walls Nusselt number; although the Nusselt number is not highly affected by surface waviness when the number of undulations is below one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavity" title="cavity">cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusselt%20number" title=" Nusselt number"> Nusselt number</a>, <a href="https://publications.waset.org/abstracts/search?q=wavy%20wall" title=" wavy wall"> wavy wall</a> </p> <a href="https://publications.waset.org/abstracts/16580/numerical-investigation-of-the-effect-of-number-of-waves-on-heat-transfer-in-a-wavy-wall-enclosure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">84</span> Optimization of Processing Parameters of Acrylonitrile–Butadiene–Styrene Sheets Integrated by Taguchi Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatemeh%20Sadat%20Miri">Fatemeh Sadat Miri</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Ehsani"> Morteza Ehsani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Farshid%20Hosseini"> Seyed Farshid Hosseini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present research is concerned with the optimization of extrusion parameters of ABS sheets by the Taguchi experimental design method. In this design method, three parameters of % recycling ABS, processing temperature and degassing time on mechanical properties, hardness, HDT, and color matching of ABS sheets were investigated. The variations of this research are the dosage of recycling ABS, processing temperature, and degassing time. According to experimental test data, the highest level of tensile strength and HDT belongs to the sample with 5% recycling ABS, processing temperature of 230°C, and degassing time of 3 hours. Additionally, the minimum level of MFI and color matching belongs to this sample, too. The present results are in good agreement with the Taguchi method.
