Furthermore, Islam did not ignore. God in Quran has used words that mean beauty many times. Zain «زین» and its synonyms are some of that words that are used 46 times in a different meaning of beauty. Some of them are mentioned to worldly beauty and not acceptable beauty and other of them are mentioned to the Moral beauty. In this article, the meaning of Zain 'beauty' in Surah Al Aaraf (The Heights) is explained and described. In fact, there are specific signs about beauty in the 31 and 32 verses of this Surah in which the station of beauty can determine. For clarification of this issue, the analytic philosophy method is used to express the relation between this word and aesthetics and beauty in this article. The results of this research show that the beauty is an important issue in Islam as much as God order to Muslims to be beautiful when they want to pray. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beauty" title="beauty">beauty</a>, <a href="https://publications.waset.org/abstracts/search?q=Quran" title=" Quran"> Quran</a>, <a href="https://publications.waset.org/abstracts/search?q=al%20zinah" title=" al zinah"> al zinah</a>, <a href="https://publications.waset.org/abstracts/search?q=Zain" title=" Zain"> Zain</a> </p> <a href="https://publications.waset.org/abstracts/53962/the-station-and-value-of-beauty-in-islam-based-on-the-holy-quran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53962.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">256</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">69</span> Diagnosis of Induction Machine Faults by DWT</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Akbari">Hamidreza Akbari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, for detection of inclined eccentricity in an induction motor, time–frequency analysis of the stator startup current is carried out.

Accordingly, we did sampling from secondary schools of education and training in Tehran, including 12 schools with levels of first, second and third. Each of the schools represents the three – high, medium and low- economic and social conditions. In the following, three classes from every school and 20 students from each class were randomly selected. By (CTQ) abused and normal students were separated that 670 children were recognized as normal and 50 children as abused. Then, 50 children were randomly selected from normal group and compared with abused group. Using Spanned-Fischer Co-dependency Scale, we compared mothers of abused and normal students. The results showed that mothers of the abused children have higher co- dependency average comparing to the mothers of the normal children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=co-dependency" title="co-dependency">co-dependency</a>, <a href="https://publications.waset.org/abstracts/search?q=child%20abuse" title=" child abuse"> child abuse</a>, <a href="https://publications.waset.org/abstracts/search?q=abused%20children" title=" abused children"> abused children</a>, <a href="https://publications.waset.org/abstracts/search?q=parental%20psychological%20health" title=" parental psychological health"> parental psychological health</a> </p> <a href="https://publications.waset.org/abstracts/42250/comparing-abused-and-normal-male-students-in-tehran-guidance-schools-emphasizing-the-co-dependency-of-their-mothers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42250.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">66</span> Acute Renal Failure Associated Tetanus Infection: A Case Report from Afghanistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shohra%20Qaderi">Shohra Qaderi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Tetanus is a severe infection characterized by the spasm of skeletal muscles that often progresses toward respiratory failure. Acute Renal failure (ARF) is an important complication associated Tetanus infection, occurring in 15%-39% of cases. Presentation of cases: A previous healthy 14-year-old boy was admitted to the Tetanus ward of a hospital in Kabul, presenting with severe muscle spasms. On day four of admission, he started having cola-colored urine with decreased urine output. Due to lack of peritoneal dialysis, he went under hemodialysis in view of rapidly raising in blood urea (from baseline 32 mg/dl to 150 mg/dl) and creatinine from (baseline 0.9 mg/dl to 6.2g/dl). Despite all efforts, he had a sudden cardiac arrest and passed away on day 6 of admission. Discussion: ARF is a complication of tetanus, reported to be mild and non-oliguric. Suggested pathological mechanisms include autonomic dysfunction and rhabdomyolysis, owing to uncontrolled muscle spasms. Autonomic dysfunction, most evident in the first two weeks of infection. Conclusion: The prevalence and mortality of tetanus is high in Afghanistan. Physicians and pediatricians need to be aware of this complication of tetanus so as to take appropriate preventive measures and recognize and manage it early. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=afghanistan" title="afghanistan">afghanistan</a>, <a href="https://publications.waset.org/abstracts/search?q=acute%20renal%20failure" title=" acute renal failure"> acute renal failure</a>, <a href="https://publications.waset.org/abstracts/search?q=child" title=" child"> child</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/135422/acute-renal-failure-associated-tetanus-infection-a-case-report-from-afghanistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/135422.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">188</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">65</span> Improving the Performance of DBE Structure in Pressure Flushing Using Submerged Vanes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Beiramipour">Sepideh Beiramipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Haghjouei"> Hadi Haghjouei</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Qaderi"> Kourosh Qaderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Rahimpour"> Majid Rahimpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20M.%20Ahmadi"> Mohammad M.

Pressure flushing method is an effective way to drain the deposited sediments of the reservoirs through the bottom outlet. So far, several structural methods have been proposed to increase the efficiency of pressure flushing. The aim of this study is to increase the performance of Dendritic Bottomless Extended (DBE) structure on the efficiency of pressurized sediment flushing using submerged vanes. For this purpose, the physical model of the dam reservoir with dimensions of 7.5 m in length, 3.5 m in width, and 1.8 m in height in the hydraulic and water structures research laboratory of Shahid Bahonar University of Kerman was used. In order to investigate the influence of submerged vanes on the performance of DBE structure in pressure flushing, the best arrangement and geometric parameters of the vanes were selected and combined with the DBE structure. The results showed that the submerged vanes significantly increased the performance of the DBE structure so that the volume of the sediment flushing cone with the combination of two structures increased by 3.7 times compared to the DBE structure test. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dendritic%20bottomless%20extended%20structure" title="dendritic bottomless extended structure">dendritic bottomless extended structure</a>, <a href="https://publications.waset.org/abstracts/search?q=flushing%20efficiency" title=" flushing efficiency"> flushing efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentation" title=" sedimentation"> sedimentation</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20flushing" title=" sediment flushing"> sediment flushing</a> </p> <a href="https://publications.waset.org/abstracts/141430/improving-the-performance-of-dbe-structure-in-pressure-flushing-using-submerged-vanes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141430.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">64</span> Numerical Study of Flow around Flat Tube between Parallel Walls</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Bayat">Hamidreza Bayat</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Mirabdolah%20Lavasani"> Arash Mirabdolah Lavasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Bolhasani"> Meysam Bolhasani</a>, <a href="https://publications.waset.org/abstracts/search?q=Sajad%20Moosavi"> Sajad Moosavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow around a flat tube is studied numerically.

It appears as unqualified and restrictive entropy, relative entropy, or common data, and has found numerous applications in information theory. In the Re ́nyi’s argument, the area law of the black hole entropy plays a significant role. However, the total entropy can be modified by some quantum effects, motivated by the randomness of a system. In this note, by employing this modified entropy relation, we have derived corrections to Friedmann equations. Taking this entropy associated with the apparent horizon of the Friedmann-Robertson-Walker Universe and assuming the first law of thermodynamics, dE=T_A (dS)_A+WdV, satisfies the apparent horizon, we have reconsidered expanding Universe.

To analyze the sensitivity of the inverster, the RSM technique is employed to manifest the effective factors in the inverter to minimize current passing through the Insulated Bipolar Gate Transistors (IGBTs) (current stress). It is revealed that the ratio of the axillary inductor to the effective inductance of resonant inverter (N), is the most effective parameter to minimize the current stress in this type of inverter. In practice, proper selection of N mitigates the current stress over IGBTs by five times. This reduction is very helpful to keep the IGBTs at normal temperatures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytical%20analysis" title="analytical analysis">analytical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20resonant%20inverter" title=" hybrid resonant inverter"> hybrid resonant inverter</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20transformer" title=" reactive transformer"> reactive transformer</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20method" title=" response surface method"> response surface method</a> </p> <a href="https://publications.waset.org/abstracts/118780/effect-of-inductance-ratio-on-operating-frequencies-of-a-hybrid-resonant-inverter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118780.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">207</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">56</span> A Study of Barriers and Challenges Associated with Agriculture E-commerce in Afghanistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khwaja%20Bahman%20Qaderi">Khwaja Bahman Qaderi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noorullah%20Rafiqee"> Noorullah Rafiqee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: With today's increasing Internet users, e-commerce has become a viable model for strengthening relationships between sellers, entrepreneurs, and consumers due to its speed, efficiency, and cost reduction. Agriculture is the economic backbone for 80 percent of the Afghan population. According to MCIT statistics, there are currently around 10 million internet users in Afghanistan. With this data, it was expected that Afghan people should have utilized e-commerce in their agricultural aspects, although it appears to be less used. Objective: This study examines the scope of e-commerce in Afghanistan's agriculture enterprises, how they harness the potential of internet users, and what obstacles they face in implementing e-commerce in their businesses. Method: The study distributed a 39-question questionnaire to agribusinesses in five different zones of Afghanistan. After extracting the responses and excluding the incomplete questionnaires, 280 were included in the analysis step to perform a non-parametric sign test. Result: E-commerce in Afghanistan faces four major political, economic, Internet, and technological obstacles, and no company in the country has implemented e-commerce. In addition, e-commerce is still in its infancy among agricultural companies in the country. Internet use is still primarily limited to email and sharing product images on Facebook & Instagram for advertising purposes. There are no companies that conduct international transactions via the Internet. Conclusion: This study contributes to knowing the challenges and barriers that the agriculture e-commerce faces in Afghanistan to find the effective solutions to use the capacity of internet users in the country and increase the sales rate of agricultural products through the Internet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E-commerce" title="E-commerce">E-commerce</a>, <a href="https://publications.waset.org/abstracts/search?q=barriers%20and%20challenges" title=" barriers and challenges"> barriers and challenges</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture%20companies" title=" agriculture companies"> agriculture companies</a>, <a href="https://publications.waset.org/abstracts/search?q=Afghanistan" title=" Afghanistan"> Afghanistan</a> </p> <a href="https://publications.waset.org/abstracts/165772/a-study-of-barriers-and-challenges-associated-with-agriculture-e-commerce-in-afghanistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165772.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">55</span> Effect of Nano-SiO2 Solution on the Strength Characteristics of Kaolinite</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed">Reza Ziaie Moayed</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Rahmani"> Hamidreza Rahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, with developments in science and technology, there is an excessive potential for the use of nanomaterials in various fields of geotechnical project such as soil stabilization.

In experimental test of moving loads that is one of the major research topics, the load is modeled as a simple moving mass or a small vehicle. This paper deals with the applicability of Non-Contact Moving Load (NML) for vibration analysis. For this purpose, an experimental set-up is designed to generate the different types of NML including constant and harmonic. The proposed method relies on pressurized air which is useful, especially when dealing with fragile or sensitive structures. To demonstrate the performance of this system, the set-up is employed for a modal analysis of a beam and detecting crack of the beam. The obtained results indicate that the experimental set-up for NML can be an attractive alternative to the moving load problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experimental%20analysis" title="experimental analysis">experimental analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20load" title=" moving load"> moving load</a>, <a href="https://publications.waset.org/abstracts/search?q=non-contact%20excitation" title=" non-contact excitation"> non-contact excitation</a>, <a href="https://publications.waset.org/abstracts/search?q=materials%20engineering" title=" materials engineering"> materials engineering</a> </p> <a href="https://publications.waset.org/abstracts/2510/design-and-manufacture-of-non-contact-moving-load-for-experimental-analysis-of-beams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2510.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">465</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">51</span> Effect of Waste Bottle Chips on Strength Parameters of Silty Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Rahmani"> Hamidreza Rahmani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Laboratory consolidated undrained triaxial (CU) tests were carried out to study the strength behavior of silty soil reinforced with randomly plastic waste bottle chips.

In view of the above, this study examines entropy generation in the stack of a thermo-acoustic system. For this purpose two parallel plates representative of the stack is considered. A general equation for entropy generation is derived based on the Second Law of thermodynamics. Assumptions such as Rott’s linear thermo-acoustic approximation, boundary layer type flow, etc. are made to simplify the governing continuity, momentum and energy equations to achieve analytical solutions for velocity and temperature. The entropy generation equation is also simplified based on the same assumptions and then is converted to dimensionless form by using characteristic entropy generation. A time averaged entropy generation rate followed by a global entropy generation rate are calculated and graphically represented for further analysis and inspecting the effect of different parameters on the entropy generation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thermo-acoustics" title="thermo-acoustics">thermo-acoustics</a>, <a href="https://publications.waset.org/abstracts/search?q=entropy" title=" entropy"> entropy</a>, <a href="https://publications.waset.org/abstracts/search?q=second%20law%20of%20thermodynamics" title=" second law of thermodynamics"> second law of thermodynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=Rott%E2%80%99s%20linear%20thermo-acoustic%20approximation" title=" Rott’s linear thermo-acoustic approximation"> Rott’s linear thermo-acoustic approximation</a> </p> <a href="https://publications.waset.org/abstracts/32388/entropy-analysis-of-a-thermo-acoustic-stack" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32388.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">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">46</span> Desalination Technologies and Desalination Integrated with Renewable Energies – A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmadali%20Shirazytabar">Ahmadali Shirazytabar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Namazi"> Hamidreza Namazi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As water resources are rapidly getting diminished, more and more interest is paid to the desalination of saline waters. Desalination has become a reliable and cost effective solution in provision of fresh water particularly in the arid areas of the world such as Middle East countries. However, the dramatic increase of utilizing desalination will cause a series of problems which are significantly related to energy consumption and environment impacts. The use of renewable energy sources to provide energy required by desalination processes is a feasible and simultaneously environmental friendly solution. In this study an attempt has been made to present a review on desalination technologies, desalination integrated with renewable energies, in brief, and practical progresses made during recent years particularly in the field of desalination by wind energy which is the most common form of renewable energies. Moreover, an economic analysis of a wind powered RO desalination system comprising of 10×2.5 MW wind turbines is done, and the results will be compared to those of a cogeneration system comprising of one 25 MW gas turbines, heat recovery steam generators (HRSG) and MED-TVC desalination. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20turbine" title="wind turbine">wind turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=desalination" title=" desalination"> desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=RO" title=" RO"> RO</a>, <a href="https://publications.waset.org/abstracts/search?q=MED" title=" MED"> MED</a>, <a href="https://publications.waset.org/abstracts/search?q=cogeneration" title=" cogeneration"> cogeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title=" gas turbine"> gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=HRSG" title=" HRSG"> HRSG</a> </p> <a href="https://publications.waset.org/abstracts/32323/desalination-technologies-and-desalination-integrated-with-renewable-energies-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32323.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">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Numerical Modeling of Flow in USBR II Stilling Basin with End Adverse Slope</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Babaali">Hamidreza Babaali</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mojtahedi"> Alireza Mojtahedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Soori"> Nasim Soori</a>, <a href="https://publications.waset.org/abstracts/search?q=Saba%20Soori"> Saba Soori</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hydraulic jump is one of the effective ways of energy dissipation in stilling basins that the &lrm;energy is highly dissipated by jumping.

For this purpose, first, organization’s most important non-financial objectives which are impacted by knowledge management processes are identified and then, using a quality house, are linked with knowledge management processes which are regarded as technical elements. Using this method, processes that are in need of improvement and more attention are prioritized based on their significance. This means that if a process has more influence on organization’s objectives and is in a dire situation comparing to others, is prioritized for choice and improvement. In this research process dominance is considered to be an influential element in process ranking (in addition to communication matrix). This is the reason for utilizing DEA techniques for prioritizing processes in quality house.

In principle, GAP intends to maintain the maximum capacity of the airport through the best possible allocation of the resources (gates) in order to reach the optimum outcome. The problem involves a wide range of dependent and independent resources and their limitations, which add to the complexity of GAP from both theoretical and practical perspective. In this study, GAP was mathematically formulated as a three-objective problem. The preliminary goal of multi-objective formulation was to address a higher number of objectives that can be simultaneously optimized and therefore increase the practical efficiency of the final solution. The problem is solved by applying the second version of Non-dominated Sorting Genetic Algorithm (NSGA-II). Results showed that the proposed mathematical model could address most of major criteria in the decision-making process in airport management in terms of minimizing both airport/airline cost and passenger walking distance time. Moreover, the proposed approach could properly find acceptable possible answers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=airport%20management" title="airport management">airport management</a>, <a href="https://publications.waset.org/abstracts/search?q=gate%20assignment%20problem" title=" gate assignment problem"> gate assignment problem</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=NSGA-II" title=" NSGA-II"> NSGA-II</a> </p> <a href="https://publications.waset.org/abstracts/63467/an-evolutionary-multi-objective-optimization-for-airport-gate-assignment-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63467.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">299</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Designing an Aerodynamic Braking in Order to Increase Power and Speed of Braking System of Vehicles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamidreza%20Ahmadi">Hamidreza Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Majid%20Abbasalizadeh"> Majid Abbasalizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghasem%20Yazdani"> Ghasem Yazdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Ahmadi"> Masoud Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a special kind of aerodynamic system as a spoiler has been designed and tried to show effects of this devise on braking system of vehicle. Moreover, position of this spoiler has been considered in order to find optimum point from safety and highest rate of braking view for spoiler. Fluent software is our main tool to calculate rate of extra force that is produced by spoiler and this article has been tried to use various figures that are showed effects of spoiler at different speeds, angles and also heights. Other major points in this paper are static pressure of vehicle at different speed and statues. Undoubtedly, shape of spoiler would be very important, so in this investigation spoiler has been designed and proposed after a lot of simulation for different shape of spoiler. In the end, there is very important part as validation since these simulations must be validated by experimental way to prove our claims. In this case, a special kind of BMW has been simulated and results have been compared by experimental results that have been presented by BMW Company. Difference between simulation results and experimental results are very little and it could be a suitable validation for this project. <p class="card-text"><strong>Keywords:</strong> <a
