A retrospective study of data collected through passive surveillance of outbreaks of FMD from 1995 to 2016 was undertaken. A total of 1471 outbreaks were reported between 1995 and 2008. Of 7776 samples originating from 34 provinces tested between 2009 and 2016 4845 (62.3%) tested positive. The prevalence varied significantly between years (2009 and 2016) (P < 0.001); however, the number of outbreaks did not differ significantly (P = 0.24) between 1995 and 2008. During this period, there was a strong correlation between the number of outbreaks reported and the number of districts with infected animals (r = 0.74, P = 0.002). Serotype O was the predominant serotype detected, although serotypes A and Asia1 were also detected. Cattle were involved in all outbreaks reported. Herat province in the north-west (bordering Iran), Nangarhar province in the east (bordering Pakistan) and Kabul province in the centre of the country had infections detected in all years of the study. The findings from this study provide valuable direction for further research to understand the epidemiology of FMD in Afghanistan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foot%20and%20mouth%20disease" title="foot and mouth disease">foot and mouth disease</a>, <a href="https://publications.waset.org/abstracts/search?q=retrospective" title=" retrospective"> retrospective</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=Afghanistan" title=" Afghanistan"> Afghanistan</a> </p> <a href="https://publications.waset.org/abstracts/97235/history-and-epidemiology-of-foot-and-mouth-disease-in-afghanistan-a-retrospective-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97235.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">146</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">78</span> Solving Optimal Control of Semilinear Elliptic Variational Inequalities Obstacle Problems using Smoothing Functions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=El%20Hassene%20Osmani">El Hassene Osmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mounir%20Haddou"> Mounir Haddou</a>, <a href="https://publications.waset.org/abstracts/search?q=Naceurdine%20Bensalem"> Naceurdine Bensalem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we investigate optimal control problems governed by semilinear elliptic variational inequalities involving constraints on the state, and more precisely, the obstacle problem.

As the innovative methodological development is evolving alongside computer sciences on one hand, researches are likely to confront more complex and larger water resources systems due to new challenges regarding increased water demands, climate change and human interventions, socio-economic concerns, and environment protection and sustainability. In this research, an automatic calibration scheme has been applied on the Gilan’s large-scale water resource model using mathematical programming. The water resource model’s calibration is developed in order to attune unknown water return flows from demand sites in the complex Sefidroud irrigation network and other related areas. The calibration procedure is validated by comparing several gauged river outflows from the system in the past with model results. The calibration results are pleasantly reasonable presenting a rational insight of the system. Subsequently, the unknown optimized parameters were used in a basin-scale linear optimization model with the ability to evaluate the system’s performance against a reduced inflow scenario in future. Results showed an acceptable match between predicted and observed outflows from the system at selected hydrometric stations. Moreover, an efficient operating policy was determined for Sefidroud dam leading to a minimum water shortage in the reduced inflow scenario. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=auto-calibration" title="auto-calibration">auto-calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilan" title=" Gilan"> Gilan</a>, <a href="https://publications.waset.org/abstracts/search?q=large-scale%20water%20resources" title=" large-scale water resources"> large-scale water resources</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/7091/auto-calibration-and-optimization-of-large-scale-water-resources-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7091.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">335</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">76</span> Moving Towards Zero Waste in a UK Local Authority Area: Challenges to the Introduction of Separate Food Waste Collections</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Cole">C.

In the work reported here the local waste collection authority (Charnwood Borough Council) has adopted the aspirational strategy of becoming a “Zero Waste Borough” to lead the drive for public participation. The work concludes that the separate collection of food waste would be needed to meet the two regulatory standards on recycling and biologically active wastes. An analysis of a neighbouring Authority (Newcastle-Under-Lyne Borough Council (NBC), a similar sized local authority that has a successful weekly food waste collection service was undertaken. Results indicate that the main challenges for Charnwood Borough Council would be gaining householder co-operation, the extra costs of collection and organising alternative treatment. The analysis also demonstrated that there was potential offset value via anaerobic digestion for CBC to overcome these difficulties and improve its recycling performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=England" title="England">England</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste%20collections" title=" food waste collections"> food waste collections</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20waste" title=" household waste"> household waste</a>, <a href="https://publications.waset.org/abstracts/search?q=local%20authority" title=" local authority "> local authority </a> </p> <a href="https://publications.waset.org/abstracts/11055/moving-towards-zero-waste-in-a-uk-local-authority-area-challenges-to-the-introduction-of-separate-food-waste-collections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11055.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">414</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">75</span> Evaluating the Topsoil and Subsoil Physical Quality Using Relative Bulk Density in Urmia Plain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Asgarzadeh">Hossein Asgarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayoub%20Osmani"> Ayoub Osmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Farrokh%20Asadzadeh"> Farrokh Asadzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Mosaddeghi"> Mohammad Reza Mosaddeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted to evaluate the topsoil and subsoil physical quality using relative bulk density (RBD) in Urmia plain in Iran. Undisturbed samples were collected from two layers (topsoil and subsoil) of thirty agricultural soils. Categories of 0.72 ≥ RBD (low degree of compactness), 0.82 > RBD > 0.72 (moderate/optimum degree of compactness), and RBD ≥ 0.82 (high degree of compactness) were used to evaluate soil physical quality (SPQ). Two topsoils had a low degree of compactness, fourteen topsoils had an optimum degree of compactness, and the rest (i.e., fourteen topsoils) had a high degree of compactness. Only one subsoil had an optimum degree of compactness, and twenty-eight subsoils (i.e., 93%) had a high degree of compactness, indicating poor SPQ of the subsoil layer in the studied region. It seems that conventional tillage in the past decades destroyed the pore system in the majority of studied subsoils. The high degree of compactness would reduce soil aeration and increase soil penetration resistance which could restrict root and plant growth. Conversely, a low degree of soil compactness is expected to reduce the root-soil contact. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compactness" title="compactness">compactness</a>, <a href="https://publications.waset.org/abstracts/search?q=relative%20bulk%20density" title=" relative bulk density"> relative bulk density</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20physical%20quality" title=" soil physical quality"> soil physical quality</a> </p> <a href="https://publications.waset.org/abstracts/151658/evaluating-the-topsoil-and-subsoil-physical-quality-using-relative-bulk-density-in-urmia-plain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151658.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">123</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">74</span> Optical Fiber Data Throughput in a Quantum Communication System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Kosari">Arash Kosari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Araghi"> Ali Araghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A mathematical model for an optical-fiber communication channel is developed which results in an expression that calculates the throughput and loss of the corresponding link.

In this paper, while presenting motion equations with six degrees of freedom for Autonomous Underwater Vehicles, Proportional Navigation Guidance Law and the first order sliding mode control for TAIPAN AUV was used to address its guidance for the purpose of collision with a moving target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Autonomous%20Underwater%20Vehicle%20%28AUV%29" title="Autonomous Underwater Vehicle (AUV)">Autonomous Underwater Vehicle (AUV)</a>, <a href="https://publications.waset.org/abstracts/search?q=degree%20of%20freedom%20%28DOF%29" title=" degree of freedom (DOF)"> degree of freedom (DOF)</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrodynamic" title=" hydrodynamic"> hydrodynamic</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20of%20sight%28LOS%29" title=" line of sight(LOS)"> line of sight(LOS)</a>, <a href="https://publications.waset.org/abstracts/search?q=proportional%20navigation%20guidance%28PNG%29" title=" proportional navigation guidance(PNG)"> proportional navigation guidance(PNG)</a>, <a href="https://publications.waset.org/abstracts/search?q=sliding%20mode%20control%28SMC%29" title=" sliding mode control(SMC) "> sliding mode control(SMC) </a> </p> <a href="https://publications.waset.org/abstracts/17056/guidance-and-control-of-a-torpedo-autonomous-underwater-vehicle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17056.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">468</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">71</span> Feedback in the Language Class: An Action Research Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Golzari%20Koloor">Arash Golzari Koloor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Feedback seems to be an inseparable part of teaching a second/foreign language. One type of feedback is corrective feedback which is one type of error treatment in second language classrooms. This study is a report on the types of corrective feedback employed in an IELTS preparation course. The types of feedback, their frequencies, and their effectiveness are enlisted, enumerated, and interpreted. The results showed that explicit correction and recast were the most frequent types of feedback while repetition and elicitation were the least. The results also revealed that metalinguistic feedback, elicitation, and explicit correction were the most effective types of feedback and affected learners performance greatly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classroom%20interaction" title="classroom interaction">classroom interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=corrective%20feedback" title=" corrective feedback"> corrective feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20treatment" title=" error treatment"> error treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20performance" title=" oral performance"> oral performance</a> </p> <a href="https://publications.waset.org/abstracts/63657/feedback-in-the-language-class-an-action-research-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63657.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">334</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">70</span> Vibration Analysis of Pendulum in a Viscous Fluid by Analytical Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Jafari">Arash Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Taghaddosi"> Mehdi Taghaddosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azin%20Parvin"> Azin Parvin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a vibrational differential equation governing on swinging single-degree-of-freedom pendulum in a viscous fluid has been investigated.

Our purpose is to enhance the ability of solving the mentioned nonlinear differential equation with a simple and innovative approach. Comparisons are made between new method and Numerical Method (rkf45). The results show that this method is very effective and simple and can be applied for other nonlinear problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oscillating%20systems" title="oscillating systems">oscillating systems</a>, <a href="https://publications.waset.org/abstracts/search?q=angular%20frequency%20and%20damping%20ratio" title=" angular frequency and damping ratio"> angular frequency and damping ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=pendulum%20at%20fluid" title=" pendulum at fluid"> pendulum at fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=locus%20of%20maximum" title=" locus of maximum"> locus of maximum</a> </p> <a href="https://publications.waset.org/abstracts/58354/vibration-analysis-of-pendulum-in-a-viscous-fluid-by-analytical-methods" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58354.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">69</span> Experimental Analysis of Tuned Liquid Damper (TLD) with Embossments Subject to Random Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Saberi">Mohamad Saberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Sohrabi"> Arash Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuned liquid damper is one the passive structural control ways which has been used since mid-1980 decade for seismic control in civil engineering.

For this purpose, livers of 40 infected sheep with D. dendriticumalong with livers of 20 healthy (control) sheep were collected from animals slaughtered in Khuzestan province, Iran. An increase in malondialdehyde concentrations accompanied by decreased activities of SOD and GPX of infected liver was noticed when com-pared with control values.

Keeping in mind this crucial fact, this study conducted different statistical and econometrical methods to identify whether the gross national income of the country has a significant impact on electricity production from nonrenewable sources and different air pollutants like carbon dioxide, nitrous oxide, and methane emissions. Besides, the primary objective of this research was to analyze whether the environmental Kuznets curve hypothesis holds for the examined variables. After analyzing different statistical properties of the variables, this study came to the conclusion that the environmental Kuznets curve hypothesis holds for gross national income and carbon dioxide emission in Bangladesh in the short run as well as the long run. This study comes to this conclusion based on the findings of ordinary least square estimations, ARDL bound tests, short-run causality analysis, the Error Correction Model, and other pre-diagnostic and post-diagnostic tests that have been employed in the structural model. Moreover, this study wants to demonstrate that the outline of gross national income and carbon dioxide emissions is in its initial stage of development and will increase up to the optimal peak. The compositional effect will then force the emission to decrease, and the environmental quality will be restored in the long run. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=environmental%20Kuznets%20curve%20hypothesis" title="environmental Kuznets curve hypothesis">environmental Kuznets curve hypothesis</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20emission%20in%20Bangladesh" title=" carbon dioxide emission in Bangladesh"> carbon dioxide emission in Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=gross%20national%20income%20in%20Bangladesh" title=" gross national income in Bangladesh"> gross national income in Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=autoregressive%20distributed%20lag%20model" title=" autoregressive distributed lag model"> autoregressive distributed lag model</a>, <a href="https://publications.waset.org/abstracts/search?q=granger%20causality" title=" granger causality"> granger causality</a>, <a href="https://publications.waset.org/abstracts/search?q=error%20correction%20model" title=" error correction model"> error correction model</a> </p> <a href="https://publications.waset.org/abstracts/145785/the-per-capita-income-energy-production-and-environmental-degradation-a-comprehensive-assessment-of-the-existence-of-the-environmental-kuznets-curve-hypothesis-in-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145785.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">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Synthesis of Metal Curcumin Complexes with Iron(III) and Manganese(II): The Effects on Alzheimer's Disease</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emel%20Yildiz">Emel Yildiz</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurcan%20Bi%C3%A7er"> Nurcan Biçer</a>, <a href="https://publications.waset.org/abstracts/search?q=Fazilet%20Aksu"> Fazilet Aksu</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Alizadeh%20Yegani"> Arash Alizadeh Yegani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Plants provide the wealth of bioactive compounds, which exert a substantial strategy for the treatment of neurological disorders such as Alzheimer's disease. Recently, a lot of studies have explored the medicinal properties of curcumin, including antitumoral, antimicrobial, anti-inflammatory, antioxidant, antiviral, and anti-Alzheimer's disease effects. Metal complexes of curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) were synthesized with Mn(II) and Fe(III). The structures of synthesized metal complexes have been characterized by using spectroscopic and analytic methods such as elemental analysis, magnetic susceptibility, FT-IR, AAS, TG and argentometric titration. It was determined that the complexes have octahedral geometry. The effects of the metal complexes on the disorder of memory, which is an important symptom of Alzheimer's Disease were studied on lab rats with Plus-Maze Tests at Behavioral Pharmacology Laboratory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=curcumin" title="curcumin">curcumin</a>, <a href="https://publications.waset.org/abstracts/search?q=Mn%28II%29" title=" Mn(II)"> Mn(II)</a>, <a href="https://publications.waset.org/abstracts/search?q=Fe%28III%29" title=" Fe(III)"> Fe(III)</a>, <a href="https://publications.waset.org/abstracts/search?q=Alzheimer%20disease" title=" Alzheimer disease"> Alzheimer disease</a>, <a href="https://publications.waset.org/abstracts/search?q=beta%20amyloid%2025-35" title=" beta amyloid 25-35"> beta amyloid 25-35</a> </p> <a href="https://publications.waset.org/abstracts/60623/synthesis-of-metal-curcumin-complexes-with-ironiii-and-manganeseii-the-effects-on-alzheimers-disease" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60623.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">301</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">61</span> Reliable Method for Estimating Rating Curves in the Natural Rivers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20%20Ahmadi">Arash Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Amirreza%20Kavousizadeh"> Amirreza Kavousizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sanaz%20Heidarzadeh"> Sanaz Heidarzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stage-discharge curve is one of the conventional methods for continuous river flow measurement. In this paper, an innovative approach is proposed for predicting the stage-discharge relationship using the application of isovel contours. Using the proposed method, it is possible to estimate the stage-discharge curve in the whole section with only using discharge information from just one arbitrary water level. For this purpose, multivariate relationships are used to determine the mean velocity in a cross-section. The unknown exponents of the proposed relationship have been obtained by using the second version of the Strength Pareto Evolutionary Algorithm (SPEA2), and the appropriate equation was selected by applying the TOPSIS (Technique for Order Preferences by Similarity to an Ideal Solution) approach. Results showed a close agreement between the estimated and observed data in the different cross-sections. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rating%20curves" title="rating curves">rating curves</a>, <a href="https://publications.waset.org/abstracts/search?q=SPEA2" title=" SPEA2"> SPEA2</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20rivers" title=" natural rivers"> natural rivers</a>, <a href="https://publications.waset.org/abstracts/search?q=bed%20roughness%20distribution" title=" bed roughness distribution"> bed roughness distribution</a> </p> <a href="https://publications.waset.org/abstracts/123107/reliable-method-for-estimating-rating-curves-in-the-natural-rivers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123107.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">158</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">60</span> Numerical Simulation of Turbulent Flow around Two Cam Shaped Cylinders in Tandem Arrangement</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Mir%20Abdolah%20Lavasani">Arash Mir Abdolah Lavasani</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Ebrahimisabet"> M.

The investigation covers the effects of high subcritical and supercritical Reynolds numbers and L/D ratio on total drag coefficient. The equivalent diameter of cylinders is 27.6 mm The space between center to center of two cam shaped cylinders is define as longitudinal pitch ratio and it varies in range of 1.5 < L/D < 6. Reynolds number base on equivalent circular cylinder varies in range of 27×103 < Re < 166×103 Results show that drag coefficient of both cylinders depends on pitch ratio.

The performance of an enterprise has a significant impact on its activities and has to be evaluated continuously. One of the most important indicators to evaluate performance is named ‘innovation’. There are various indicators of innovation in the product/service sectors. These cause different innovation types to emerge, in product sectors. Additionally there are basic enablers to these innovation types, including an innovative culture, a customer oriented organizational culture, etc. Also one of these enablers is called enterprise system, which includes: SCM, CRM, ERP, KM etc. Knowledge management as a solution is a necessity in a competitive world. Implementation solutions such as KM are expensive, so enterprises need to answer how KM systems affect different performance indicators like innovation. This paper aims to develop a model to evaluate the impact of KM on innovation in SMEs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=innovation" title="innovation">innovation</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge%20management" title=" knowledge management"> knowledge management</a>, <a href="https://publications.waset.org/abstracts/search?q=SMEs" title=" SMEs"> SMEs</a>, <a href="https://publications.waset.org/abstracts/search?q=enterprise" title=" enterprise"> enterprise</a> </p> <a href="https://publications.waset.org/abstracts/26071/the-impact-of-knowledge-management-on-different-innovation-types-in-small-and-medium-enterprises" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26071.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">693</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">58</span> War Heritage: Different Perceptions of the Dominant Discourse among Visitors to the “Adem Jashari” Memorial Complex in Prekaz</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zana%20Llon%C3%A7ari%20Osmani">Zana Llonçari Osmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nita%20Llon%C3%A7ari"> Nita Llonçari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In Kosovo, public rhetoric and popular sentiment position the War of 1998-99 (the war) as central to the formation of contemporary Kosovo's national identity. This period was marked by the forced massive displacement of Kosovo Albanians, the destruction of entire settlements, the loss of family members, and the profound emotional trauma experienced by civilians, particularly those who actively participated in the war as members of the Kosovo Liberation Army (KLA). Amidst these profound experiences, the Prekaz Massacre (The Massacre) is widely regarded as the defining event that preceded the final struggles of 1999 and the long-awaited attainment of independence. This study aims to explore how different visitors perceive the dominant discourse at The Memorial, a site dedicated to commemorating the Prekaz Massacre, and to identify the factors that influence their perceptions. The research employs a comprehensive mixed-method approach, combining online surveys, critical discourse analysis of visitor impressions, and content analysis of media representations. The findings of the study highlight the significant role played by original material remains in shaping visitor perceptions of The Memorial in comparison to the curated symbols and figurative representations interspersed throughout the landscape. While the design elements and physical layout of the memorial undeniably hold significance in conveying the memoryscape, there are notable shortcomings in enhancing the overall visitor experience. Visitors are still primarily influenced by the tangible remnants of the war, suggesting that there is room for improvement in how design elements can more effectively contribute to the memorial's narrative and the collective memory of the Prekaz Massacre. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=critical%20discourse%20analysis" title="critical discourse analysis">critical discourse analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=memorialisation" title=" memorialisation"> memorialisation</a>, <a href="https://publications.waset.org/abstracts/search?q=national%20discourse" title=" national discourse"> national discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20rhetoric" title=" public rhetoric"> public rhetoric</a>, <a href="https://publications.waset.org/abstracts/search?q=war%20tourism" title=" war tourism"> war tourism</a> </p> <a href="https://publications.waset.org/abstracts/175091/war-heritage-different-perceptions-of-the-dominant-discourse-among-visitors-to-the-adem-jashari-memorial-complex-in-prekaz" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175091.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">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Optimal Design of Redundant Hybrid Manipulator for Minimum Singularity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Rahmani">Arash Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Ghanbari"> Ahmad Ghanbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Baghernezhad"> Abbas Baghernezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Safaei"> Babak Safaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the design of parallel manipulators, usually mean value of a dexterity measure over the workspace volume is considered as the objective function to be used in optimization algorithms. The mentioned indexes in a hybrid parallel manipulator (HPM) are quite complicated to solve thanks to infinite solutions for every point within the workspace of the redundant manipulators. In this paper, spatial isotropic design axioms are extended as a well-known method for optimum design of manipulators. An upper limit for the isotropy measure of HPM is calculated and instead of computing and minimizing isotropy measure, minimizing the obtained limit is considered. To this end, two different objective functions are suggested which are obtained from objective functions of comprising modules. Finally, by using genetic algorithm (GA), the best geometric parameters for a specific hybrid parallel robot which is composed of two modified Gough-Stewart platforms (MGSP) are achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20manipulator" title="hybrid manipulator">hybrid manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20isotropy" title=" spatial isotropy"> spatial isotropy</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=optimum%20design" title=" optimum design"> optimum design</a> </p> <a href="https://publications.waset.org/abstracts/41885/optimal-design-of-redundant-hybrid-manipulator-for-minimum-singularity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41885.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">336</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> Responses of Trifolium pratense to Lead Accumulation Under In-Vitro Culture Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Khorasani%20Esmaeili">Arash Khorasani Esmaeili</a>, <a href="https://publications.waset.org/abstracts/search?q=Rosna%20Mat%20Taha"> Rosna Mat Taha</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadegh%20Mohajer"> Sadegh Mohajer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Seeds of Trifolium pratense (Red clover) were exposed in vitro for 6 weeks to six levels of lead (Pb) concentrations (0, 50, 100, 150, 200, 250 µM) to analyze the effects on growth, total chlorophyll and total protein contents of grown plants against the lead accumulation.

That is why this article seeks to dissect the security dilemma and rebuild it from its foundational core. In doing so, the present study highlights that the security dilemma requires interaction among actors that seek to protect themselves from other's capacity for harm under the condition of uncertainty to operate. In this constellation, actors are confronted with the dilemma of motives, power, and action, which they seek to resolve by acquiring information regarding their opponents. The relationship between the parties is shaped by the harm-uncertainty index (HUI) consisting of geographical distance, MAD, and joint democracy that determines the intensity of the security dilemma. These elements define the unified theory of the security dilemma (UTSD) developed here. UTSD challenges the prevailing view that the security dilemma is a unidimensional paradoxical concept, regulated by the offense-defense balance and differentiation that only occurs in anarchic settings with tragic outcomes and is equivalent to the spiral model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=security%20dilemma" title="security dilemma">security dilemma</a>, <a href="https://publications.waset.org/abstracts/search?q=revisionism" title=" revisionism"> revisionism</a>, <a href="https://publications.waset.org/abstracts/search?q=status%20quo" title=" status quo"> status quo</a>, <a href="https://publications.waset.org/abstracts/search?q=anarchy" title=" anarchy"> anarchy</a>, <a href="https://publications.waset.org/abstracts/search?q=uncertainty" title=" uncertainty"> uncertainty</a>, <a href="https://publications.waset.org/abstracts/search?q=tragedy" title=" tragedy"> tragedy</a>, <a href="https://publications.waset.org/abstracts/search?q=spiral" title=" spiral"> spiral</a>, <a href="https://publications.waset.org/abstracts/search?q=deterrence" title=" deterrence"> deterrence</a> </p> <a href="https://publications.waset.org/abstracts/141491/unified-theory-of-the-security-dilemma-geography-mad-and-democracy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141491.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">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">54</span> Analytical Solving of Nonlinear Differential Equations in the Nonlinear Phenomena for Viscos Fluids </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Jafari">Arash Jafari</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Taghaddosi"> Mehdi Taghaddosi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azin%20Parvin"> Azin Parvin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the paper, our purpose is to enhance the ability to solve a nonlinear differential equation which is about the motion of an incompressible fluid flow going down of an inclined plane without thermal effect with a simple and innovative approach which we have named it new method. Comparisons are made amongst the Numerical, new method, and HPM methods, and the results reveal that this method is very effective and simple and can be applied to other nonlinear problems. It is noteworthy that there are some valuable advantages in this way of solving differential equations, and also most of the sets of differential equations can be answered in this manner which in the other methods they do not have acceptable solutions up to now. A summary of the excellence of this method in comparison to the other manners is as follows: 1) Differential equations are directly solvable by this method. 2) Without any dimensionless procedure, we can solve equation(s). 3) It is not necessary to convert variables into new ones. According to the afore-mentioned assertions which will be proved in this case study, the process of solving nonlinear equation(s) will be very easy and convenient in comparison to the other methods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=viscos%20fluid" title="viscos fluid">viscos fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=incompressible%20fluid%20flow" title=" incompressible fluid flow"> incompressible fluid flow</a>, <a href="https://publications.waset.org/abstracts/search?q=inclined%20plane" title=" inclined plane"> inclined plane</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20phenomena" title=" nonlinear phenomena"> nonlinear phenomena</a> </p> <a href="https://publications.waset.org/abstracts/58352/analytical-solving-of-nonlinear-differential-equations-in-the-nonlinear-phenomena-for-viscos-fluids" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">283</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">53</span> A Genetic Algorithm Based Sleep-Wake up Protocol for Area Coverage in WSNs </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mahdi%20Jameii">Seyed Mahdi Jameii</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Nikdel"> Arash Nikdel</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohsen%20Jameii"> Seyed Mohsen Jameii</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Energy efficiency is an important issue in the field of Wireless Sensor Networks (WSNs).

Considering BIM's weaknesses in implementing existing heritage and historical buildings, it is critical to facilitate BIM application for such structures. One of the pieces of information to build a model in BIM is to import material and its characteristics. Material library is essential to speed up the entry of project information. To save time and prevent cost overrun, a BIM object material library should be provided. However, historical buildings' lack of information and documents is typically a challenge in renovation and retrofitting projects. Due to the lack of case documents for historic buildings, importing data is a time-consuming task, which can be improved by creating BIM libraries. Based on previous research, this paper reviews the complexities and challenges in BIM modeling for heritage, historic, and architectural buildings. Through identifying the strengths and weaknesses of the standard BIM systems, recommendations are provided to enhance the modeling platform. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=building%20Information%20modeling" title="building Information modeling">building Information modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=historic" title=" historic"> historic</a>, <a href="https://publications.waset.org/abstracts/search?q=heritage%20buildings" title=" heritage buildings"> heritage buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20library" title=" material library"> material library</a> </p> <a href="https://publications.waset.org/abstracts/146808/a-review-of-bim-applications-for-heritage-and-historic-buildings-challenges-and-solutions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146808.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">117</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">50</span> Assessment of Carbon Dioxide Separation by Amine Solutions Using Electrolyte Non-Random Two-Liquid and Peng-Robinson Models: Carbon Dioxide Absorption Efficiency </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Esmaeili">Arash Esmaeili</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhibang%20Liu"> Zhibang Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yang%20Xiang"> Yang Xiang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimmy%20Yun"> Jimmy Yun</a>, <a href="https://publications.waset.org/abstracts/search?q=Lei%20Shao"> Lei Shao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A high pressure carbon dioxide (CO<sub>2</sub>) absorption from a specific gas in a conventional column has been evaluated by the Aspen HYSYS simulator using a wide range of single absorbents and blended solutions to estimate the outlet CO<sub>2</sub> concentration, absorption efficiency and CO<sub>2</sub> loading to choose the most proper solution in terms of CO<sub>2 </sub>capture for environmental concerns. The property package (Acid Gas-Chemical Solvent) which is compatible with all applied solutions for the simulation in this study, estimates the properties based on an electrolyte non-random two-liquid (E-NRTL) model for electrolyte thermodynamics and Peng-Robinson equation of state for the vapor and liquid hydrocarbon phases. Among all the investigated single amines as well as blended solutions, piperazine (PZ) and the mixture of piperazine and monoethanolamine (MEA) have been found as the most effective absorbents respectively for CO<sub>2</sub> absorption with high reactivity based on the simulated operational conditions. <p class="card-text"><strong>Keywords:</strong> <a
