of engineering structures, because the accuracy of predictions of theoretical–numerical procedures can be assessed. 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">29</span> WAQF Financing Using WAQF Sukuk in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Doaei">Meysam Doaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Kavand"> Mojtaba Kavand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> WAQF as a part of Islamic social security system is developed in Islam.

Occasionally, in order to increase productivity index and porosity of the wellbore and reservoir, the well stimulation methods have been used. Hydraulic fracturing is one of these methods. Moreover, several explosions at the end of the well can stimulate the reservoir and create fractures around it. In this study, crack initiation in rock around the wellbore has been numerically modeled due to explosion. One, two, three, and four pairs of explosion have been set at the end of the wellbore on its wall. After each stage of the explosion, results have been presented and discussed. Results show that this method can initiate and probably propagate several fractures around the wellbore. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crack%20initiation" title="crack initiation">crack initiation</a>, <a href="https://publications.waset.org/abstracts/search?q=explosion" title=" explosion"> explosion</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20difference%20modelling" title=" finite difference modelling"> finite difference modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=well%20productivity" title=" well productivity"> well productivity</a> </p> <a href="https://publications.waset.org/abstracts/84207/numerical-modelling-of-crack-initiation-around-a-wellbore-due-to-explosion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84207.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">290</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">23</span> Better Knowledge and Understanding of the Behavior of Masonry Buildings in Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20R.%20Mirzaee">A.

Three types of loadings and two types of glass-epoxy composite sequences: [0/90]2s and [0/45/-45/90]s are considered for the composite plate and their results are compared. It was seen that generally the cases with stacking sequence of [0/45/-45/90]s have much shorter lives than cases with [0/90]2s. It was also seen that in cases with λ=0 the ends of the debonding front propagates forward more than its middle, while in cases with λ=0.5 or λ=1 it is vice versa. Moreover, regardless of value of λ, the difference between the debonding propagations of the ends and the middle of the debonding front is very close in cases λ=0.5 and λ=1. Another main conclusion was the non-dimensionalized debonding front profile is almost independent of sequence type or the applied load value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adhesive%20joint" title="adhesive joint">adhesive joint</a>, <a href="https://publications.waset.org/abstracts/search?q=debonding" title=" debonding"> debonding</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture" title=" fracture"> fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=LEFM" title=" LEFM"> LEFM</a>, <a href="https://publications.waset.org/abstracts/search?q=APDL" title=" APDL"> APDL</a> </p> <a href="https://publications.waset.org/abstracts/23751/fatigue-induced-debonding-propagation-in-fm300-adhesive" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23751.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">362</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">21</span> Engineering Optimization of Flexible Energy Absorbers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Hedayati">Reza Hedayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Jahanbakhshi"> Meysam Jahanbakhshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Elastic energy absorbers which consist of a ring-liked plate and springs can be a good choice for increasing the impact duration during an accident.

Results showed the superiority of PLBA over the other algorithms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Concurrent%20Subspace%20Design%20%28CSD%29" title="Concurrent Subspace Design (CSD)">Concurrent Subspace Design (CSD)</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuhn-Tucker" title=" Kuhn-Tucker"> Kuhn-Tucker</a>, <a href="https://publications.waset.org/abstracts/search?q=Pshenichny-Lim-Belegundu-Arora%20%28PLBA%29" title=" Pshenichny-Lim-Belegundu-Arora (PLBA)"> Pshenichny-Lim-Belegundu-Arora (PLBA)</a>, <a href="https://publications.waset.org/abstracts/search?q=Sequential%20Linear%20Programming%20%28SLP%29" title=" Sequential Linear Programming (SLP)"> Sequential Linear Programming (SLP)</a> </p> <a href="https://publications.waset.org/abstracts/23842/engineering-optimization-of-flexible-energy-absorbers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23842.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">399</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> Prediction of Fatigue Crack Propagation in Bonded Joints Using Fracture Mechanics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reza%20Hedayati">Reza Hedayati</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Jahanbakhshi"> Meysam Jahanbakhshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fracture Mechanics is used to predict debonding propagation in adhesive joint between aluminum and composite plates. Three types of loadings and two types of glass-epoxy composite sequences: [0/90]2s and [0/45/-45/90]s are considered for the composite plate and their results are compared. It was seen that generally the cases with stacking sequence of [0/45/-45/90]s have much shorter lives than cases with [0/90]2s. It was also seen that in cases with λ=0 the ends of the debonding front propagates forward more than its middle, while in cases with λ=0.5 or λ=1 it is vice versa. Moreover, regardless of value of λ, the difference between the debonding propagations of the ends and the middle of the debonding front is very close in cases λ=0.5 and λ=1. Another main conclusion was the non-dimensionalized debonding front profile is almost independent of sequence type or the applied load value. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatigue" title="fatigue">fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=debonding" title=" debonding"> debonding</a>, <a href="https://publications.waset.org/abstracts/search?q=Paris%20law" title=" Paris law"> Paris law</a>, <a href="https://publications.waset.org/abstracts/search?q=APDL" title=" APDL"> APDL</a>, <a href="https://publications.waset.org/abstracts/search?q=adhesive" title=" adhesive"> adhesive</a> </p> <a href="https://publications.waset.org/abstracts/23771/prediction-of-fatigue-crack-propagation-in-bonded-joints-using-fracture-mechanics" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23771.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">363</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> Background Knowledge and Reading Comprehension in ELT Classes: A Pedagogical Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Davoud%20Ansari%20Kejal">Davoud Ansari Kejal</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Sabour"> Meysam Sabour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For long, there has been a belief that a reader can easily comprehend a text if he is strong enough in vocabulary and grammatical knowledge but there was no account for the ability of understanding different subjects based on readers’ understanding of the surrounding world which is called world background knowledge.

Generally, riveted joints hold the plates together and their failure may create accidents. In this study, well known active and passive methods were modified for the evaluation of the health of the riveted joints between the plates. The active method generated Lamb waves and monitored their propagation by using lead zirconate titanate (PZT) disks. The signal was analyzed by using the wavelet transformations. The passive method used the Fiber Bragg Grating (FBG) sensors and evaluated the spectral characteristics of the signals by using Fast Fourier Transformation (FFT).

The new experimental rig is indeed a spinning frame structure with multiple wheel components over a fixed rail-track ring, capable of simulating continuous wheel-rail contact in a laboratory scale. This paper describes the dimensional design of the rig, to derive its overall scaling strategy and to determine the key elements’ specifications. Finite element (FE) modelling is used to simulate the mechanical behavior of the rig with two sample scale factors of 1/5 and 1/7. The results of FE models are compared with the actual railway system to observe the effectiveness of the chosen scales.

Deficit irrigation is a strategy that allows a crop to sustain some degree of water deficit in order to reduce costs and potentially increase income. For this goal, a field experimental carried out at Asrieh fields of Gorgan city in the north of Iran, during summer season 2011. The treatments imposed were different irrigation water regimes (i.e. W1:70, W2:80, W3:90, and W4:100) percent of field capacity (FC). The results showed that there was Significant difference between the yield and (WUE) under different levels of irrigation, excepting of soil moisture content at field capacity (W4) and 90% of field capacity (W3) on yield and water use efficiency (WUE). The seasonal irrigation water applied were (i.e. 375, 338, 300, and 263 mm ha-1) under different irrigation water treatments (100, 90, 80, 80 and 70%) of FC, respectively. Grain yield productions under treatments were 4180, 3955, 3640, and 3355 (kg ha-1) respectively. Furthermore, the results showed that water use efficiency (WUE) at different treatments were 7.67, 7.79, 7.74, and 7.75 Kg mm ha-1 for (100, 90, 80, and 70) per cent of field capacity, therefore the 90 % of FC treatment (W3) is recommended for Soybean irrigation for water saving. Furthermore, the result showed that the treatment of 90 % of filed capacity (W3) seemed to be better adapted to product a high crop yield with acceptable yield coupling with water use efficiency in Golestan province. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deficit%20irrigation" title="deficit irrigation">deficit irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20use%20efficiency" title=" water use efficiency"> water use efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a> </p> <a href="https://publications.waset.org/abstracts/16412/assessment-of-yield-and-water-use-efficiency-of-soybean-under-deficit-irrigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16412.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">469</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> Dental Appointments and Related Fear and Anxiety among the General Population during the COVID-19 Pandemic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Paria%20Koraei">Paria Koraei</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Ahmadzadeh"> Meysam Ahmadzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Shahriarirad"> Reza Shahriarirad</a>, <a href="https://publications.waset.org/abstracts/search?q=Keivan%20Ranjbar"> Keivan Ranjbar</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzane%20Farahmand"> Farzane Farahmand</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The rapid spread of the coronavirus disease 2019 (COVID-19) has enlisted dental offices in high-risk places. A cross-sectional survey was carried out among the general population aged 17 and above in Shiraz, Fars, Iran. The patients' demographic features were recorded and analyzed against questions regarding fear, anxiety, and attitude toward dental appointments. The Dental Anxiety Scale (DAS) questionnaire was used for the evaluation of anxiety levels. Among a total of 760 participants, the average age was 32.33±11.27 years, while 242 (31.8%) were male and 357 (47%) were single. Based on the anxiety scores, 336 (44.2%) participants had mild anxiety, 215 (28.3%) had moderate anxiety, 74 (9.7%) had high, and 135 (17.8%) had severe anxiety. The majority of participants used masks (93.8%) and disinfectants (79.9%) during dental visits, and the most emphasized policies during dental visits were using disposable face masks by the personnel (83.6%) and controlling the number of visitors in the office (81.8%). Only 226 (29.7%) reported that they hadn’t postponed their dental visits. Our findings demonstrated that anxiety in people increases toward dental treatments during the COVID-19 pandemic, resulting in decreased dental appointments. Dentally anxious people were more likely to be female and married couples. Being female and older age are possible risk factors for developing a fear of dental procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Covid-19" title="Covid-19">Covid-19</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=fear" title=" fear"> fear</a>, <a href="https://publications.waset.org/abstracts/search?q=dentistry" title=" dentistry"> dentistry</a>, <a href="https://publications.waset.org/abstracts/search?q=dental%20care" title=" dental care"> dental care</a> </p> <a href="https://publications.waset.org/abstracts/175926/dental-appointments-and-related-fear-and-anxiety-among-the-general-population-during-the-covid-19-pandemic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175926.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">92</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> Economical and Technical Analysis of Urban Transit System Selection Using TOPSIS Method According to Constructional and Operational Aspects </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Abdi%20Kordani">Ali Abdi Kordani</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Rooyintan"> Meysam Rooyintan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sid%20Mohammad%20Boroomandrad"> Sid Mohammad Boroomandrad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, one the most important problems in megacities is public transportation and satisfying citizens from this system in order to decrease the traffic congestions and air pollution. Accordingly, to improve the transit passengers and increase the travel safety, new transportation systems such as Bus Rapid Transit (BRT), tram, and monorail have expanded that each one has different merits and demerits. That is why comparing different systems for a systematic selection of public transportation systems in a big city like Tehran, which has numerous problems in terms of traffic and pollution, is essential. In this paper, it is tried to investigate the advantages and feasibility of using monorail, tram and BRT systems, which are widely used in most of megacities in all over the world. In Tehran, by using SPSS statistical analysis software and TOPSIS method, these three modes are compared to each other and their results will be assessed. Experts, who are experienced in the transportation field, answer the prepared matrix questionnaire to select each public transportation mode (tram, monorail, and BRT). The results according to experts’ judgments represent that monorail has the first priority, Tram has the second one, and BRT has the third one according to the considered indices like execution costs, wasting time, depreciation, pollution, operation costs, travel time, passenger satisfaction, benefit to cost ratio and traffic congestion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BRT" title="BRT">BRT</a>, <a href="https://publications.waset.org/abstracts/search?q=costs" title=" costs"> costs</a>, <a href="https://publications.waset.org/abstracts/search?q=monorail" title=" monorail"> monorail</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=tram" title=" tram"> tram</a> </p> <a href="https://publications.waset.org/abstracts/109783/economical-and-technical-analysis-of-urban-transit-system-selection-using-topsis-method-according-to-constructional-and-operational-aspects" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109783.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">177</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> A Review on New Additives in Deep Soil Mixing Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Mousakhani">Meysam Mousakhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ziaie%20Moayed"> Reza Ziaie Moayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Considering the population growth and the needs of society, the improvement of problematic soils and the study of the application of different improvement methods have been considered. One of these methods is deep soil mixing, which has been developed in the past decade, especially in soft soils due to economic efficiency, simple implementation, and other benefits. The use of cement is criticized for its cost and the damaging environmental effects, so these factors lead us to use other additives along with cement in the deep soil mixing. Additives that are used today include fly ash, blast-furnace slag, glass powder, and potassium hydroxide. The present study provides a literature review on the application of different additives in deep soil mixing so that the best additives can be introduced from strength, economic, environmental and other perspectives. The results show that by replacing fly ash and slag with about 40 to 50% of cement, not only economic and environmental benefits but also a long-term strength comparable to cement would be achieved. The use of glass powder, especially in 3% mixing, results in desirable strength. In addition to the other benefits of these additives, potassium hydroxide can also be transported over longer distances, leading to wider soil improvement. Finally, this paper suggests further studies in terms of using other additives such as nanomaterials and zeolite, with different ratios, in different conditions and soils (silty sand, clayey sand, carbonate sand, sandy clay and etc.) in the deep mixing method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deep%20soil%20mix" title="deep soil mix">deep soil mix</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20stabilization" title=" soil stabilization"> soil stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=fly%20ash" title=" fly ash"> fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20improvement" title=" ground improvement"> ground improvement</a> </p> <a href="https://publications.waset.org/abstracts/133452/a-review-on-new-additives-in-deep-soil-mixing-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133452.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Understanding Seismic Behavior of Masonry Buildings in Earthquake</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Mirzaee">Alireza Mirzaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Soosan%20Abdollahi"> Soosan Abdollahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Abdollahi"> Mohammad Abdollahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Unreinforced Masonry (URM) wall is vulnerable in resisting horizontal load such as wind and seismic loading. It is due to the low tensile strength of masonry, the mortar connection between the brick units. URM structures are still widely used in the world as an infill wall and commonly constructed with door and window openings. This research aimed to investigate the behavior of URM wall with openings when horizontal load acting on it and developed load-drift relationship of the wall. The finite element (FE) method was chosen to numerically simulate the behavior of URM with openings. In this research, ABAQUS, commercially available FE software with explicit solver was employed. In order to ensure the numerical model can accurately represent the behavior of an URM wall, the model was validated for URM wall without openings using available experimental results. Load-displacement relationship of numerical model is well agreed with experimental results. Evidence shows the same load displacement curve shape obtained from the FE model. After validating the model, parametric study conducted on URM wall with openings to investigate the influence of area of openings and pre-compressive load on the horizontal load capacity of the wall. The result showed that the increasing of area of openings decreases the capacity of the wall in resisting horizontal loading. It is also well observed from the result that capacity of the wall increased with the increasing of pre-compressive load applied on the top of the walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=masonry%20constructions" title="masonry constructions">masonry constructions</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20at%20earthquake" title=" performance at earthquake"> performance at earthquake</a>, <a href="https://publications.waset.org/abstracts/search?q=MSJC-08%20%28ASD%29" title=" MSJC-08 (ASD)"> MSJC-08 (ASD)</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20wall" title=" bearing wall"> bearing wall</a>, <a href="https://publications.waset.org/abstracts/search?q=tie-column" title=" tie-column"> tie-column</a> </p> <a href="https://publications.waset.org/abstracts/53817/understanding-seismic-behavior-of-masonry-buildings-in-earthquake" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53817.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">251</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> Substantial Fatigue Similarity of a New Small-Scale Test Rig to Actual Wheel-Rail System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Naeimi">Meysam Naeimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zili%20Li"> Zili Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Roumen%20Petrov"> Roumen Petrov</a>, <a href="https://publications.waset.org/abstracts/search?q=Rolf%20Dollevoet"> Rolf Dollevoet</a>, <a href="https://publications.waset.org/abstracts/search?q=Jilt%20Sietsma"> Jilt Sietsma</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Wu"> Jun Wu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The substantial similarity of fatigue mechanism in a new test rig for rolling contact fatigue (RCF) has been investigated. A new reduced-scale test rig is designed to perform controlled RCF tests in wheel-rail materials. The fatigue mechanism of the rig is evaluated in this study using a combined finite element-fatigue prediction approach. The influences of loading conditions on fatigue crack initiation have been studied. Furthermore, the effects of some artificial defects (squat-shape) on fatigue lives are examined. To simulate the vehicle-track interaction by means of the test rig, a three-dimensional finite element (FE) model is built up. The nonlinear material behaviour of the rail steel is modelled in the contact interface. The results of FE simulations are combined with the critical plane concept to determine the material points with the greatest possibility of fatigue failure. Based on the stress-strain responses, by employing of previously postulated criteria for fatigue crack initiation (plastic shakedown and ratchetting), fatigue life analysis is carried out. The results are reported for various loading conditions and different defect sizes. Afterward, the cyclic mechanism of the test rig is evaluated from the operational viewpoint. The results of fatigue life predictions are compared with the expected number of cycles of the test rig by its cyclic nature. Finally, the estimative duration of the experiments until fatigue crack initiation is roughly determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatigue" title="fatigue">fatigue</a>, <a href="https://publications.waset.org/abstracts/search?q=test%20rig" title=" test rig"> test rig</a>, <a href="https://publications.waset.org/abstracts/search?q=crack%20initiation" title=" crack initiation"> crack initiation</a>, <a href="https://publications.waset.org/abstracts/search?q=life" title=" life"> life</a>, <a href="https://publications.waset.org/abstracts/search?q=rail" title=" rail"> rail</a>, <a href="https://publications.waset.org/abstracts/search?q=squats" title=" squats"> squats</a> </p> <a href="https://publications.waset.org/abstracts/18986/substantial-fatigue-similarity-of-a-new-small-scale-test-rig-to-actual-wheel-rail-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18986.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">515</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">7</span> Transformation of Positron Emission Tomography Raw Data into Images for Classification Using Convolutional Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pawe%C5%82%20Konieczka">Paweł Konieczka</a>, <a href="https://publications.waset.org/abstracts/search?q=Lech%20Raczy%C5%84ski"> Lech Raczyński</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Wi%C5%9Blicki"> Wojciech Wiślicki</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleksandr%20Fedoruk"> Oleksandr Fedoruk</a>, <a href="https://publications.waset.org/abstracts/search?q=Konrad%20Klimaszewski"> Konrad Klimaszewski</a>, <a href="https://publications.waset.org/abstracts/search?q=Przemys%C5%82aw%20Kopka"> Przemysław Kopka</a>, <a href="https://publications.waset.org/abstracts/search?q=Wojciech%20Krzemie%C5%84"> Wojciech Krzemień</a>, <a href="https://publications.waset.org/abstracts/search?q=Roman%20Shopa"> Roman Shopa</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Baran"> Jakub Baran</a>, <a href="https://publications.waset.org/abstracts/search?q=Aur%C3%A9lien%20Coussat"> Aurélien Coussat</a>, <a href="https://publications.waset.org/abstracts/search?q=Neha%20Chug"> Neha Chug</a>, <a href="https://publications.waset.org/abstracts/search?q=Catalina%20Curceanu"> Catalina Curceanu</a>, <a href="https://publications.waset.org/abstracts/search?q=Eryk%20Czerwi%C5%84ski"> Eryk Czerwiński</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Dadgar"> Meysam Dadgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamil%20Dulski"> Kamil Dulski</a>, <a href="https://publications.waset.org/abstracts/search?q=Aleksander%20Gajos"> Aleksander Gajos</a>, <a href="https://publications.waset.org/abstracts/search?q=Beatrix%20C.%20Hiesmayr"> Beatrix C.

In positron emission tomography (PET) studies, CNN may be applied directly to the reconstructed distribution of radioactive tracers injected into the patient's body, as a pattern recognition tool. Nonetheless, much PET data still exists in non-image format and this fact opens a question on whether they can be used for training CNN. In this contribution, the main focus of this paper is the problem of processing vectors with a small number of features in comparison to the number of pixels in the output images. The proposed methodology was applied to the classification of PET coincidence events. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=convolutional%20neural%20network" title="convolutional neural network">convolutional neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=kernel%20principal%20component%20analysis" title=" kernel principal component analysis"> kernel principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20imaging" title=" medical imaging"> medical imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=positron%20emission%20tomography" title=" positron emission tomography"> positron emission tomography</a> </p> <a href="https://publications.waset.org/abstracts/150734/transformation-of-positron-emission-tomography-raw-data-into-images-for-classification-using-convolutional-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150734.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">143</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> Effects of High-Protein, Low-Energy Diet on Body Composition in Overweight and Obese Adults: A Clinical Trial</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Makan%20Cheraghpour">Makan Cheraghpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ahmad%20Hosseini"> Seyed Ahmad Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Damoon%20Ashtary-Larky"> Damoon Ashtary-Larky</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Shirali"> Saeed Shirali</a>, <a href="https://publications.waset.org/abstracts/search?q=Matin%20Ghanavati"> Matin Ghanavati</a>, <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Alipour"> Meysam Alipour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: In addition to reducing body weight, the low-calorie diets can reduce the lean body mass. It is hypothesized that in addition to reducing the body weight, the low-calorie diets can maintain the lean body mass. So, the current study aimed at evaluating the effects of high-protein diet with calorie restriction on body composition in overweight and obese individuals. Methods: 36 obese and overweight subjects were divided randomly into two groups. The first group received a normal-protein, low-energy diet (RDA), and the second group received a high-protein, low-energy diet (2×RDA). The anthropometric indices including height, weight, body mass index, body fat mass, fat free mass, and body fat percentage were evaluated before and after the study. Results: A significant reduction was observed in anthropometric indices in both groups (high-protein, low-energy diets and normal-protein, low-energy diets). In addition, more reduction in fat free mass was observed in the normal-protein, low-energy diet group compared to the high -protein, low-energy diet group. In other the anthropometric indices, significant differences were not observed between the two groups. Conclusion: Independently of the type of diet, low-calorie diet can improve the anthropometric indices, but during a weight loss, high-protein diet can help the fat free mass to be maintained. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diet" title="diet">diet</a>, <a href="https://publications.waset.org/abstracts/search?q=high-protein" title=" high-protein"> high-protein</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20mass%20index" title=" body mass index"> body mass index</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20fat%20percentage" title=" body fat percentage"> body fat percentage</a> </p> <a href="https://publications.waset.org/abstracts/58466/effects-of-high-protein-low-energy-diet-on-body-composition-in-overweight-and-obese-adults-a-clinical-trial" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58466.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">308</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> Geomorphology of Karst Features of Shiraz City and Arjan Plain and Development Limitations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Meysam%20Jamali">Meysam Jamali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Moghimi"> Ebrahim Moghimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zean%20Alabden%20Jafarpour"> Zean Alabden Jafarpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Karst term is the determiner of a variety of areas or landforms and unique perspectives that have been formed in result of the ingredients dissolution of rocks constituter by natural waters. Shiraz area with an area of 5322km2 is located in the simple folded belt in the southern part of Zagros Mountain of Fars, and is surrounded with Limestone Mountains (Asmari formation). Shiraz area is located in Calcareous areas. The Infrastructure of this city is lime and absorbing wells that the city has, can influence on the Limestone dissolution and those accelerate its rate and increases the cavitation below the surface. Dasht-e Arjan is a graben, which has been created as the result of activity of two normal faults in its east and west sides. It is a complete sample of Karst plains (Polje) which has been created with the help of tectonic forces (fault) and dissolution process of water in Asmari limestone formation. It is located 60km. off south west of Shiraz (on Kazeroon-Shiraz road). In 1971, UNESCO has recognized this plain as a reserve of biosphere. It is considered as one of the world’s most beautiful geological phenomena, so that most of the world’s geologists are interested in visiting this place.

Unofficial data indicate that the Islamic Finance market is growing with annual rate of 15% and it has reached 1.3 $ trillion size. This trend is associated with inherent systematic connection of Islamic financial institutions to other entities and different sectors of economies. Islamic banking has been subject of market development policies in major economies, most notably the UK. This trend highlights the need for identification of distinct risk features of Islamic banking and crafting customized regulatory measures. So far there has not been a significant systemic crisis in this market which can be attributed to its distinct nature. However, the significant growth and spread of its products worldwide necessitate an in depth study of its nature for customized congruent regulatory measures. In the post financial crisis era some market analysis and reports suggested that the Islamic banks fairly weathered the crisis. As far as heavily blamed conventional financial products such as subprime mortgage backed securities and speculative credit default swaps were concerned the immunity claim can be considered true, as Islamic financial institutions were not directly exposed to such products. Nevertheless, similar to the experience of the conventional banking industry, it can be only a matter of time for Islamic banks to face failures that can be specific to the nature of their business. Using the experience of conventional banking regulations and identifying those peculiarities of Islamic banking that need customized regulatory approach can aid to prevent major failures. Frank Knight has stated that “We perceive the world before we react to it, and we react not to what we perceive, but always to what we infer”. The debate over congruent Islamic banking regulations might not be an exception to Frank Knight’s statement but I will try to base my discussion on concrete evidences. This paper first analyzes both theoretical and actual features of Islamic banking in order to ascertain to its peculiarities in terms of market stability and other externalities. Next, the paper discusses distinct features of Islamic financial transactions and banking which might require customized regulatory measures. Finally, the paper explores how a more transparent path for the Islamic banking regulations can be drawn. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Islamic%20banking" title="Islamic banking">Islamic banking</a>, <a href="https://publications.waset.org/abstracts/search?q=regulation" title=" regulation"> regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=risks" title=" risks"> risks</a>, <a href="https://publications.waset.org/abstracts/search?q=capital%20requirements" title=" capital requirements"> capital requirements</a>, <a href="https://publications.waset.org/abstracts/search?q=customer%20protection" title=" customer protection"> customer protection</a>, <a href="https://publications.waset.org/abstracts/search?q=financial%20stability" title=" financial stability"> financial stability</a> </p> <a href="https://publications.waset.org/abstracts/11792/finding-the-right-regulatory-path-for-islamic-banking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11792.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">409</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> Gender-Transformative Education: A Pathway to Nourishing and Evolving Gender Equality in the Higher Education of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sepideh%20Mirzaee">Sepideh Mirzaee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gender-transformative (G-TE) education is a challenging concept in the field of education and it is a matter of hot debate in the contemporary world. Paulo Freire as the prominent advocate of transformative education considers it as an alternative to conventional banking model of education. Besides, a more inclusive concept has been introduced, namely, G-TE, as an unbiased education fostering an environment of gender justice. As its main tenet, G-TE eliminates obstacles to education and improves social shifts. A plethora of contemporary research indicates that G-TE could completely revolutionize education systems by displacing inequalities and changing gender stereotypes. Despite significant progress in female education and its effects on gender equality in Iran, challenges persist. There are some deficiencies regarding gender disparities in the society and, education, specifically. As an example, the number of women with university degrees is on the rise; thus, there will be an increasing demand for employment in the society by them. Instead, many job opportunities remain occupied by men and it is seen as intolerable for the society to assign such occupations to women. In fact, Iran is regarded as a patriarchal society where educational contexts can play a critical role to assign gender ideology to its learners. Thus, such gender ideologies in the education can become the prevailing ideologies in the entire society. Therefore, improving education in this regard, can lead to a significant change in a society subsequently influencing the status of women not only within their own country but also on a global scale. Notably, higher education plays a vital role in this empowerment and social change. Particularly higher education can have a crucial part in imparting gender neutral ideologies to its learners and bringing about substantial change. It has the potential to alleviate the detrimental effects of gender inequalities. Therefore, this study aims to conceptualize the pivotal role of G-TE and its potential power in developing gender equality within the higher educational system of Iran presented within a theoretical framework. The study emphasizes the necessity of stablishing a theoretical grounding for citizenship, and transformative education while distinguishing gender related issues including gender equality, equity and parity. This theoretical foundation will shed lights on the decisions made by policy-makers, syllabus designers, material developers, and specifically professors and students. By doing so, they will be able to promote and implement gender equality recognizing the determinants, obstacles, and consequences of sustaining gender-transformative approaches in their classes within the Iranian higher education system. The expected outcomes include the eradication of gender inequality, transformation of gender stereotypes and provision of equal opportunities for both males and females in education. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citizenship%20education" title="citizenship education">citizenship education</a>, <a href="https://publications.waset.org/abstracts/search?q=gender%20inequality" title=" gender inequality"> gender inequality</a>, <a href="https://publications.waset.org/abstracts/search?q=higher%20education" title=" higher education"> higher education</a>, <a href="https://publications.waset.org/abstracts/search?q=patriarchal%20society" title=" patriarchal society"> patriarchal society</a>, <a href="https://publications.waset.org/abstracts/search?q=transformative%20education" title=" transformative education"> transformative education</a> </p> <a href="https://publications.waset.org/abstracts/171135/gender-transformative-education-a-pathway-to-nourishing-and-evolving-gender-equality-in-the-higher-education-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171135.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">65</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> Inflation and Deflation of Aircraft's Tire with Intelligent Tire Pressure Regulation System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Mirzaee">Masoud Mirzaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghobad%20Behzadi%20Pour"> Ghobad Behzadi Pour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An aircraft tire is designed to tolerate extremely heavy loads for a short duration. The number of tires increases with the weight of the aircraft, as it is needed to be distributed more evenly. Generally, aircraft tires work at high pressure, up to 200 psi (14 bar; 1,400 kPa) for airliners and higher for business jets. Tire assemblies for most aircraft categories provide a recommendation of compressed nitrogen that supports the aircraft’s weight on the ground, including a mechanism for controlling the aircraft during taxi, takeoff; landing; and traction for braking. Accurate tire pressure is a key factor that enables tire assemblies to perform reliably under high static and dynamic loads. Concerning ambient temperature change, considering the condition in which the temperature between the origin and destination airport was different, tire pressure should be adjusted and inflated to the specified operating pressure at the colder airport. This adjustment superseding the normal tire over an inflation limit of 5 percent at constant ambient temperature is required because the inflation pressure remains constant to support the load of a specified aircraft configuration. On the other hand, without this adjustment, a tire assembly would be significantly under/over-inflated at the destination. Due to an increase of human errors in the aviation industry, exorbitant costs are imposed on the airlines for providing consumable parts such as aircraft tires. The existence of an intelligent system to adjust the aircraft tire pressure based on weight, load, temperature, and weather conditions of origin and destination airports, could have a significant effect on reducing the aircraft maintenance costs, aircraft fuel and further improving the environmental issues related to the air pollution. An intelligent tire pressure regulation system (ITPRS) contains a processing computer, a nitrogen bottle with 1800 psi, and distribution lines. Nitrogen bottle’s inlet and outlet valves are installed in the main wheel landing gear’s area and are connected through nitrogen lines to main wheels and nose wheels assy. Controlling and monitoring of nitrogen will be performed by a computer, which is adjusted according to the calculations of received parameters, including the temperature of origin and destination airport, the weight of cargo loads and passengers, fuel quantity, and wind direction. Correct tire inflation and deflation are essential in assuring that tires can withstand the centrifugal forces and heat of normal operations, with an adequate margin of safety for unusual operating conditions such as rejected takeoff and hard landings. ITPRS will increase the performance of the aircraft in all phases of takeoff, landing, and taxi. Moreover, this system will reduce human errors, consumption materials, and stresses imposed on the aircraft body. <p class="card-text"><strong>Keywords:</strong> <a
