inflectional subject-object-verb language. This fact makes Persian a more uncertain language. However, using techniques such as Zero-Width Non-Joiner (ZWNJ) recognition, punctuation restoration, and Persian Ezafe construction will lead us to a more understandable and precise language. In most of the works in Persian, these techniques are addressed individually. Despite that, we believe that for text refinement in Persian, all of these tasks are necessary. In this work, we proposed a ViraPart framework that uses embedded ParsBERT in its core for text clarifications. First, used the BERT variant for Persian followed by a classifier layer for classification procedures. Next, we combined models outputs to output cleartext. In the end, the proposed model for ZWNJ recognition, punctuation restoration, and Persian Ezafe construction performs the averaged F1 macro scores of 96.90%, 92.13%, and 98.50%, respectively. Experimental results show that our proposed approach is very effective in text refinement for the Persian language. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Persian%20Ezafe" title="Persian Ezafe">Persian Ezafe</a>, <a href="https://publications.waset.org/abstracts/search?q=punctuation" title=" punctuation"> punctuation</a>, <a href="https://publications.waset.org/abstracts/search?q=ZWNJ" title=" ZWNJ"> ZWNJ</a>, <a href="https://publications.waset.org/abstracts/search?q=NLP" title=" NLP"> NLP</a>, <a href="https://publications.waset.org/abstracts/search?q=ParsBERT" title=" ParsBERT"> ParsBERT</a>, <a href="https://publications.waset.org/abstracts/search?q=transformers" title=" transformers"> transformers</a> </p> <a href="https://publications.waset.org/abstracts/143102/virapart-a-text-refinement-framework-for-automatic-speech-recognition-and-natural-language-processing-tasks-in-persian" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143102.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">215</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">258</span> Wear Characteristics of Al Based Composites Fabricated with Nano Silicon Carbide Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Koushki%20Ardestani">Mohammad Reza Koushki Ardestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Daneshmand"> Saeed Daneshmand</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Heydari%20Vini"> Mohammad Heydari Vini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present study, AA7075/SiO2 composites have been fabricated via liquid metallurgy process. Using the degassing process, the wet ability of the molten aluminum alloys increased which improved the bonding between aluminum matrix and reinforcement (SiO2) particles. AA7075 alloy and SiO2 particles were taken as the base matrix and reinforcements, respectively. Then, contents of 2.5 and 5 wt. % of SiO2 subdivisions were added into the AA7075 matrix. To improve wettability and distribution, reinforcement particles were pre-heated to a temperature of 550°C for each composite sample. A uniform distribution of SiO2 particles was observed through the matrix alloy in the microstructural study. A hardened EN32 steel disc as the counter face was used to evaluate the wear rate pin-on-disc, a wear testing machine containing. The results showed that the wear rate of the AA/SiO2 composites was lesser than that of the monolithic AA7075 samples. Finally, The SEM worn surfaces of samples were investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al7075" title="Al7075">Al7075</a>, <a href="https://publications.waset.org/abstracts/search?q=SiO%E2%82%82" title=" SiO₂"> SiO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=wear" title=" wear"> wear</a>, <a href="https://publications.waset.org/abstracts/search?q=composites" title=" composites"> composites</a>, <a href="https://publications.waset.org/abstracts/search?q=stir%20casting" title=" stir casting"> stir casting</a> </p> <a href="https://publications.waset.org/abstracts/178160/wear-characteristics-of-al-based-composites-fabricated-with-nano-silicon-carbide-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178160.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">101</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">257</span> Effect of Plastic Fines on Undrained Behavior of Clayey Sands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Talamkhani">Saeed Talamkhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhassan%20Naeini"> Seyed Abolhassan Naeini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years, the occurrence of several liquefactions in sandy soils containing various values of clay content has shown that in addition to silty sands, clayey sands are also susceptible to liquefaction. Therefore, it is necessary to investigate the properties of these soil compositions and their behavioral characteristics. This paper presents the effect of clay fines on the undrained shear strength of sands at various confining pressures. For this purpose, a series of unconsolidated undrained triaxial shear tests were carried out on clean sand and sand mixed with 5, 10, 15, 20, and 30 percent of clay fines. It was found that the presence of clay particle in sandy specimens change the dilative behavior to contraction. The result also showed that increasing the clay fines up to 10 percent causes to increase the potential for liquefaction, and decreases it at higher values fine content. These results reveal the important role of clay particles in changing the undrained strength of the sandy soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clayey%20sand" title="clayey sand">clayey sand</a>, <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title=" liquefaction"> liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=triaxial%20test" title=" triaxial test"> triaxial test</a>, <a href="https://publications.waset.org/abstracts/search?q=undrained%20shear%20strength" title=" undrained shear strength "> undrained shear strength </a> </p> <a href="https://publications.waset.org/abstracts/93873/effect-of-plastic-fines-on-undrained-behavior-of-clayey-sands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93873.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">196</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">256</span> The Relationship between Anatomical Components of Mosques and Place Attachment with Respect to Islamic Wisdom and Art</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alitajer%20Saeed">Alitajer Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Negintaji%20Farshad"> Negintaji Farshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has been examined the relationship between anatomical components of mosques and place attachment of people to anatomies of mosques with the approach of attending to Islamic wisdom.

It is located along the central axial line of the vessel, and therefore will highly affect the neutronic parameters of the reactor, so from the neutronics point of view, C.T.L is the most important facility. It is mainly designed for fuel testing, thought other applications such as radioisotope production and neutron activation, can be imagine for it. All of the simulations were performed by MCNPX2.6. As a first step towards C.T.L analysis, the effect of D2O-filled, H2O-filled, and He-filled C.T.L on the effective multiplication factor (Keff.), have been evaluated. According to results, H2O-filled C.T.L has a higher thermal neutron, while He-filled C.T.L includes more resonance neutrons. In the next step thermal and total axial neutron fluxes, were calculated and used as the comparison parameters. The core without C.T.L (C.T.L replaced by heavy water) is selected as the reference case, and the effect of all other cases is calculated according to that. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heavy%20water%20reactor" title="heavy water reactor">heavy water reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=neutronic%20calculations" title=" neutronic calculations"> neutronic calculations</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20test%20loop" title=" central test loop"> central test loop</a>, <a href="https://publications.waset.org/abstracts/search?q=neutron%20activation" title=" neutron activation"> neutron activation</a> </p> <a href="https://publications.waset.org/abstracts/64952/neutronic-calculations-for-central-test-loop-in-heavy-water-research-reactor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64952.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">254</span> Sedentary Behaviour and Metabolic Rate among Adults Professionals: An Intervention Approach (E-Mobile)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahsan%20Ullah">Ahsan Ullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to measure the relationship between sedentary behaviour and metabolic rate among adult professionals. An intervention (e-mobile) approach was used for gathered the information from the participants. A total of 40 participants (men = 30, and women = 10) with an average age of (36.53 years ± 8.85) were randomly assigned to an intervention group (n= 20) and control group (n= 20). All the participants completed the Sedentary Behaviour Questionnaire (SBQ) and The International Physical Activity Questionnaire (IPAQ) at baseline and at the end of eight weeks. The participants in the intervention group were given physical activity guidelines targeted at increasing physical activity levels during daily activities. On the other side, the control group was advised to continue with their routine daily physical activity. Statistical analyses, including descriptive statistics and inferential analysis like mean, SD, T-tests, and ANOVA, were used to analyze the data and determine relationships between variables. After analyzing the data, the results showed that significant difference in pre and post metabolic rate scores (1488.31 ± 179.13 to 1468.44 ± 128.19) (f = 10.83, p < 0.000) were noted in the experimental group after eight week. The experimental group increased their walking (863.78 METs per week to 1625.55 METs per week), moderate activity (295 METs per week to 743 METs per week) and vigorous activity (362 METs per week to 1366 METs per week) physical activity (all p<0.001). There were no significant differences observed in any outcome measured before and after eight weeks in the control group. These findings suggest that engaging in physical activity can effectively improve metabolic rate and reduce sedentary behavior among physically active adults. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sedentary%20behavior" title="sedentary behavior">sedentary behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolic%20rate" title=" metabolic rate"> metabolic rate</a>, <a href="https://publications.waset.org/abstracts/search?q=adult%E2%80%99s%20professionals" title=" adult’s professionals"> adult’s professionals</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20activity" title=" physical activity"> physical activity</a> </p> <a href="https://publications.waset.org/abstracts/191855/sedentary-behaviour-and-metabolic-rate-among-adults-professionals-an-intervention-approach-e-mobile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191855.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">26</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">253</span> Measuring Text-Based Semantics Relatedness Using WordNet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Madiha%20Khan">Madiha Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Sidrah%20Ramzan"> Sidrah Ramzan</a>, <a href="https://publications.waset.org/abstracts/search?q=Seemab%20Khan"> Seemab Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahzad%20Hassan"> Shahzad Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamran%20Saeed"> Kamran Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Measuring semantic similarity between texts is calculating semantic relatedness between texts using various techniques. Our web application (Measuring Relatedness of Concepts-MRC) allows user to input two text corpuses and get semantic similarity percentage between both using WordNet. Our application goes through five stages for the computation of semantic relatedness. Those stages are: Preprocessing (extracts keywords from content), Feature Extraction (classification of words into Parts-of-Speech), Synonyms Extraction (retrieves synonyms against each keyword), Measuring Similarity (using keywords and synonyms, similarity is measured) and Visualization (graphical representation of similarity measure). Hence the user can measure similarity on basis of features as well. The end result is a percentage score and the word(s) which form the basis of similarity between both texts with use of different tools on same platform. In future work we look forward for a Web as a live corpus application that provides a simpler and user friendly tool to compare documents and extract useful information. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Graphviz%20representation" title="Graphviz representation">Graphviz representation</a>, <a href="https://publications.waset.org/abstracts/search?q=semantic%20relatedness" title=" semantic relatedness"> semantic relatedness</a>, <a href="https://publications.waset.org/abstracts/search?q=similarity%20measurement" title=" similarity measurement"> similarity measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=WordNet%20similarity" title=" WordNet similarity"> WordNet similarity</a> </p> <a href="https://publications.waset.org/abstracts/95106/measuring-text-based-semantics-relatedness-using-wordnet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95106.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">237</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">252</span> A Numerical Study on the Effects of N2 Dilution on the Flame Structure and Temperature Distribution of Swirl Diffusion Flames</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasaman%20Tohidi">Yasaman Tohidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Shidvash%20Vakilipour"> Shidvash Vakilipour</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ebadi%20Tavallaee"> Saeed Ebadi Tavallaee</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Vakilipoor%20Takaloo"> Shahin Vakilipoor Takaloo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Amiri"> Hossein Amiri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The numerical modeling is performed to study the effects of N<sub>2</sub> addition to the fuel stream on the flame structure and temperature distribution of methane-air swirl diffusion flames with different swirl intensities. The Open source Field Operation and Manipulation (OpenFOAM) has been utilized as the computational tool. Flamelet approach along with modified k-ε model is employed to model the flame characteristics.  The results indicate that the presence of N<sub>2</sub> in the fuel stream leads to the flame temperature reduction. By increasing of swirl intensity, the flame structure changes significantly. The flame has a conical shape in low swirl intensity; however, it has an hour glass-shape with a shorter length in high swirl intensity. The effects of N<sub>2</sub> dilution decrease the flame length in all swirl intensities; however, the rate of reduction is more noticeable in low swirl intensity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=swirl%20diffusion%20flame" title="swirl diffusion flame">swirl diffusion flame</a>, <a href="https://publications.waset.org/abstracts/search?q=N2%20dilution" title=" N2 dilution"> N2 dilution</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenFOAM" title=" OpenFOAM"> OpenFOAM</a>, <a href="https://publications.waset.org/abstracts/search?q=swirl%20intensity" title=" swirl intensity"> swirl intensity</a> </p> <a href="https://publications.waset.org/abstracts/105300/a-numerical-study-on-the-effects-of-n2-dilution-on-the-flame-structure-and-temperature-distribution-of-swirl-diffusion-flames" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105300.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">169</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">251</span> Numerical Investigation of the Effect of Number of Waves on Heat Transfer in a Wavy Wall Enclosure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Reza%20Tahavvor">Ali Reza Tahavvor</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Hosseini"> Saeed Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Afshin%20Karimzadeh%20Fard"> Afshin Karimzadeh Fard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the effect of wall waviness of side walls in a two-dimensional wavy enclosure is numerically investigated. Two vertical wavy walls and straight top wall are kept isothermal and the bottom wall temperature is higher and spatially varying with cosinusoidal temperature distribution. A computational code based on Finite-volume approach is used to solve governing equations and SIMPLE method is used for pressure velocity coupling. Test is performed for several different numbers of undulations. The Prandtl number was kept constant and the Ra number denotes that the flow is laminar. Temperature and velocity fields are determined. Therefore, according to the obtained results a correlation is proposed for average Nusselt number as a function of number of side wall waves. The results indicate that the Nusselt number is highly affected by number of waves and increasing it decreases the wavy walls Nusselt number; although the Nusselt number is not highly affected by surface waviness when the number of undulations is below one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cavity" title="cavity">cavity</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20convection" title=" natural convection"> natural convection</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusselt%20number" title=" Nusselt number"> Nusselt number</a>, <a href="https://publications.waset.org/abstracts/search?q=wavy%20wall" title=" wavy wall"> wavy wall</a> </p> <a href="https://publications.waset.org/abstracts/16580/numerical-investigation-of-the-effect-of-number-of-waves-on-heat-transfer-in-a-wavy-wall-enclosure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16580.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">250</span> Evaluation of Dynamic Log Files for Different Dose Rates in IMRT Plans </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saad%20Bin%20Saeed">Saad Bin Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Fayzan%20Ahmed"> Fayzan Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahbaz%20Ahmed"> Shahbaz Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Hussain"> Amjad Hussain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study is to evaluate dynamic log files (Dynalogs) at different dose rates by dose-volume histograms (DVH) and used as a (QA) procedure of IMRT. Seven patients of phase one head and neck cancer with similar OAR`s are selected randomly. Reference plans of dose rate 300 and 600 MU/Min with prescribed dose of 50Gy in 25 fractions for each patient is made. Dynalogs produced by delivery of reference plans processed by in-house MATLAB program which produces new field files contain actual positions of multi-leaf collimators (MLC`s) instead of planned positions in reference plans. Copies of reference plans are used to import new field files generated by MATLAB program and renamed as Dyn.plan. After dose calculations of Dyn.plans for different dose rates, DVH, and multiple linear regression tools are used to evaluate reference and Dyn.plans. The results indicate good agreement of correlation between different dose rate plans. The maximum dose difference among PTV and OAR`s are found to be less than 5% and 9% respectively. The study indicates the potential of dynalogs to be used as patient-specific QA of IMRT at different dose rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=IMRT" title="IMRT">IMRT</a>, <a href="https://publications.waset.org/abstracts/search?q=dynalogs" title=" dynalogs"> dynalogs</a>, <a href="https://publications.waset.org/abstracts/search?q=dose%20rate" title=" dose rate"> dose rate</a>, <a href="https://publications.waset.org/abstracts/search?q=DVH" title=" DVH"> DVH</a> </p> <a href="https://publications.waset.org/abstracts/24120/evaluation-of-dynamic-log-files-for-different-dose-rates-in-imrt-plans" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24120.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">535</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">249</span> Synthesis and Antibacterial Evaluation of Natural Bioactive 3,4-DihydroisocoumarinAnalogues</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hummera%20Rafique">Hummera Rafique</a>, <a href="https://publications.waset.org/abstracts/search?q=Aamer%20Saeed"> Aamer Saeed </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Synthesis of structural analogues of various well known bioactive natural 3,4-dihydroisocoumarins viz.

The alkaline hydrolysis of isocoumarins yields keto-acids (3a-e), which were then reduced to hydroxyacids, followed by cyclodehydration with acetic anhydride furnish corresponding 3,4-dihydroisocoumarins (7a-e). Finally, demethylation of 3,4-dihydroisocoumarins was carried out to afford 6,8-dihydroxy-7-methyl-3-aryl-3,4-dihydroisocoumarins (7a-e). Antibacterial evaluation of all the synthesized compounds were carried out against ten bacterial strains, it was concluded that isocoumarins (5a-e) and 3,4-dihydroisocoumarins (7a-e) are more active against gram positive bacteria then gram negative.

The entire world is threatened by only few sophisticated terrorist groups and especially in Gulf Region and Pakistan, it has become extremely destructive phenomena in recent years. Predicting the pattern of attack type, attack group and target type is an intricate task. This study offers new insight on terrorist group’s attack type and its chosen target. This research paper proposes a framework for prediction of terrorist attacks using the historical data and making an association between terrorist group, their attack type and target. Analysis shows that the number of attacks per year will keep on increasing, and Al-Harmayan in Saudi Arabia, Al-Qai’da in Gulf Region and Tehreek-e-Taliban in Pakistan will remain responsible for many future terrorist attacks. Top main targets of each group will be private citizen & property, police, government and military sector under constant circumstances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title="data mining">data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=counter%20terrorism" title=" counter terrorism"> counter terrorism</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=SVM" title=" SVM"> SVM</a> </p> <a href="https://publications.waset.org/abstracts/59817/data-analysis-to-uncover-terrorist-attacks-using-data-mining-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59817.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">408</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">246</span> Exploring the Biochemical and Therapeutic Properties of Aged Garlic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farhan%20Saeed">Farhan Saeed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The core objective of this work is to explicate the biochemical and therapeutic properties of aged garlic. For this purpose, two varieties of garlic were obtained from Ayub Agricultural Research Institute (AARI) Faisalabad-Pakistan. Additionally, fresh garlic was converted into aged garlic via fermentation method in the incubator at 70 to 80 % humidity level and 60C0 temperature for one month. Similarly, biochemical and antioxidant properties of fresh and aged garlic were also elucidated. Mean values showed that moisture content was decreased, whereas crude fat, crude protein, crude fiber, crude ash and total carbohydrates were enhanced after fermentation. Additionally, crude protein of fresh and aged garlic was 7.57±0.16 and 5.52±0.12%, respectively, whilst 9.68±0.41 and 8.78±0.29%, respectively, after the fermentation process. In addition, NFE contents were also enhanced up to 39% after the fermentation method. Moreover, Zn, S, Al, K, Fe, Na, Mg, and Cu contents were also increased. Furthermore, Total phenolic contents (TPC) of fresh and aged garlic were 2498.70 & 2188.50mg GAE/kg whilst 3008.59, & 2591.81mg GAE/kg for aged garlic.

(Hymenoptera: Apidae) was reared artificially in this experiment at varying diets including royal jelly. Larval duration, pupal duration, weight, and size of pupae were evaluated at different diets including royal jelly. Queen larvae were raised by Doo Little grafting method. Four different diets were mixed with royal jelly and applied to larvae. Fructose, sugar, yeast, and honey were provided to rearing queen larvae along with same amount of royal jelly. Larval and pupal duration were longest (6.15 and 7.5 days, respectively) at yeast and shortest on honey (5.05 and 7.02 days, respectively). Heavier and bigger pupae were recorded on yeast (168.14 mg and 1.76 cm, respectively) followed by diets having sugar and honey. Due to production of heavier and bigger pupae, yeast was considered as best artificial diet for the growing queen larvae. So, in the second part of experiment, different amounts of yeast were provided to growing larvae along with fixed amount (0.5 g) of royal jelly. Survival rates of the larvae and queen bee were 70% and 40% in the 4-g food, 86.7% and 53.3% in the 6-g food, and 76.7% and 50% in the 8-g food. Weight of adult queen bee (1.459±0.191 g) and the number of ovarioles (41.7±21.3) were highest at 8 g of food. Results of this study are helpful for bee-keepers in producing fitter queen bees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apis%20melifera%20l" title="apis melifera l">apis melifera l</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20effect" title=" dietary effect"> dietary effect</a>, <a href="https://publications.waset.org/abstracts/search?q=survival%20and%20development" title=" survival and development"> survival and development</a>, <a href="https://publications.waset.org/abstracts/search?q=honey%20bee%20queen" title=" honey bee queen"> honey bee queen</a> </p> <a href="https://publications.waset.org/abstracts/57578/effect-of-varying-diets-on-growth-development-and-survival-of-queen-bee-apis-mellifera-l-in-captivity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57578.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">490</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">243</span> Systematic NIR of Internal Disorder and Quality Detection of Apple Fruit </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eid%20Alharbi">Eid Alharbi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yaser%20Miaji"> Yaser Miaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Alzahrani"> Saeed Alzahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The importance of fruit quality and freshness is potential in today’s life. Most recent studies show and automatic online sorting system according to the internal disorder for fresh apple fruit has developed by using near infrared (NIR) spectroscopic technology. The automatic convener belts system along with sorting mechanism was constructed. To check the internal quality of the apple fruit, apple was exposed to the NIR radiations in the range 650-1300 nm and the data were collected in form of absorption spectra. The collected data were compared to the reference (data of known sample) analyzed and an electronic signal was pass to the sorting system. The sorting system was separate the apple fruit samples according to electronic signal passed to the system. It is found that absorption of NIR radiation in the range 930-950 nm was higher in the internally defected samples as compared to healthy samples. On the base of this high absorption of NIR radiation in 930-950 nm region the online sorting system was constructed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mechatronics%20design" title="mechatronics design">mechatronics design</a>, <a href="https://publications.waset.org/abstracts/search?q=NIR" title=" NIR"> NIR</a>, <a href="https://publications.waset.org/abstracts/search?q=fruit%20quality" title=" fruit quality"> fruit quality</a>, <a href="https://publications.waset.org/abstracts/search?q=spectroscopic%20technology" title=" spectroscopic technology"> spectroscopic technology</a> </p> <a href="https://publications.waset.org/abstracts/26715/systematic-nir-of-internal-disorder-and-quality-detection-of-apple-fruit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26715.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">496</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">242</span> Cultural Analysis of Dowry System with Relation to Women Prestige in District Swabi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ullah%20Aman">Ullah Aman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The practice of giving dowry was meant to assist a newly-wed couple to start their life together with ease; however, now it has turned into a commercial transaction in which monetary considerations receive priority over the personal merits of the bride. The present study was designed to explore the causes and consequences of dowry system and to measure the association between dowry and women prestige in district Swabi. A sample size of 378 household (female) Respondents was randomly selected through proportional allocation method. The data was interpreted into frequency and percentages while to measure the relationship between Dowry system and Women Prestige, Chi-Square statistic was applied. Result indicated that majority of the 316(83.6%) respondents stated that Family members are in favor of high dowry because high dowry is today’s women need which is disclosed by 302(79.9%) of the sample size. In addition to this, most 320(84.7%) of the respondents has opined that low dowry leads to broken families in the society. Moreover, a strong association (p=0.000) was determined between high dowry and women prestige. Similarly, a strong significant relation was found (p=0.000) between women prestige and low dowry mortifying women prestige in our society. The study concluded that dowry, deeply rooted in the society is an immorality which must be strictly banned in the country. It is a herculean task to completely eliminate dowry system from the nation but slowly and gradually efforts are being made in this direction. Dowry is a sure cause of promoting intense conflicts between the families, quarrels and inculcates greed in the society. Government and the builders of the social fabric should strictly work on it, banning this system for each and every class in Pakistan. Moreover, for curbing this mal practice we must put effort to bring social awareness to the society are some of the recommendation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dowry" title="Dowry">Dowry</a>, <a href="https://publications.waset.org/abstracts/search?q=women" title=" women"> women</a>, <a href="https://publications.waset.org/abstracts/search?q=prestige" title=" prestige"> prestige</a>, <a href="https://publications.waset.org/abstracts/search?q=causes" title=" causes"> causes</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/94046/cultural-analysis-of-dowry-system-with-relation-to-women-prestige-in-district-swabi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94046.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">153</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">241</span> The Effectiveness of Psychodrama in the Reduction of Social Anxiety Disorder among Male Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Dehnavi">Saeed Dehnavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Hadadi"> Zahra Hadadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Marzieh%20Rezabeigi"> Marzieh Rezabeigi</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Monirpoor"> Nader Monirpoor</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study has been performed with the goal of investigating the effectiveness of psychodrama in the reduction of social anxiety among the male adolescents in Kermanshah. 210 adolescents (13-14 year-olds) from four junior high schools in Kermanshah filled Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA) (Masia-Warner, Klien & Liebowitz, 2003). 30 of the adolescents who obtained the highest scores in LSAS-CA scale were chosen as the sample and were randomly assigned as experimental group (15 people) and control group (15 people).

Turtles are exotic species from chelonians, which are interested by many people. Caspian pond and European pond turtles from Emydidea family are commonly kept as pets in Iran. Presence of the shell in turtles makes achievement to a comprehensive clinical examination impossible. Respiratory system is one of the most important structures to be examined completely. Presence of the air in the respiratory system makes radiography the first modality to think of; however, image quality would be affected by the shell. Computed tomography (CT) as a radiography-based and non-invasive technique provides cross-sectional scans with little superimposition. The aim of this study was to depict normal computed tomographic anatomy of the respiratory system in Caspian Pond Turtle. Five adult Caspian pond turtle were scanned using a 16-detector CT machine. Our results showed that computed tomography is able to well illustrated different parts of respiratory system in turtle and can be used for detecting abnormalities and disorders. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anatomy" title="anatomy">anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=computed%20tomography" title=" computed tomography"> computed tomography</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20system" title=" respiratory system"> respiratory system</a>, <a href="https://publications.waset.org/abstracts/search?q=turtle" title=" turtle"> turtle</a> </p> <a href="https://publications.waset.org/abstracts/97439/evaluation-of-computed-tomographic-anatomy-of-respiratory-system-in-caspian-pond-turtle-mauremys-caspica" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97439.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">201</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">239</span> High Temperature Oxidation of Cr-Steel Interconnects in Solid Oxide Fuel Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Ghali">Saeed Ghali</a>, <a href="https://publications.waset.org/abstracts/search?q=Azza%20Ahmed"> Azza Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Taha%20Mattar"> Taha Mattar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid Oxide Fuel Cell (SOFC) is a promising solution for the energy resources leakage. Ferritic stainless steel becomes a suitable candidate for the SOFCs interconnects due to the recent advancements. Different steel alloys were designed to satisfy the needed characteristics in SOFCs interconnect as conductivity, thermal expansion and corrosion resistance. Refractory elements were used as alloying elements to satisfy the needed properties. The oxidation behaviour of the developed alloys was studied where the samples were heated for long time period at the maximum operating temperature to simulate the real working conditions. The formed scale and oxidized surface were investigated by SEM. Microstructure examination was carried out for some selected steel grades. The effect of alloying elements on the behaviour of the proposed interconnects material and the performance during the working conditions of the cells are explored and discussed.

They were recruited from the three public middle schools in Xi’an, a middle-sized city in the central part of China. Meditation analysis revealed that self-control mediated the relationship between parental warm support and academic achievement. Additionally, it was found the direct effect of parental warm support was not significant after controlling for the age and gender. Furthermore, moderation analysis revealed high parental warm support and higher teacher emotional support was related to increased self-control compared to lower teacher emotion support.

Therefore, the loss of data can be life-threatening when the sensed phenomenon is not disseminated due to sudden node failure, battery depletion or temporary malfunctioning. We introduce a set of partial differential equations for localizing faults, similar to Green’s and Maxwell’s equations used in Electrostatics and Electromagnetism. We introduce a node organization and clustering scheme for self-stabilizing sensor networks. Green’s theorem is applied to regions where the curve is closed and continuously differentiable to ensure network connectivity.

Adoption of modern irrigation technology is considered to be a key of increasing the efficiency of water used in agriculture. Policy makers have implemented several ways to induce the adoption of new irrigation technology. The empirical studies show that farmers are reluctant to utilize the use of new irrigation methods. This study aims to assess factors affecting on farmer’s decision on the application of water saving technologies with emphasize on crop price variation and water sources. A Logit model was employed to examine the impact of different variables on use of water saving technology. The required data gathered from a sample of 204 farmers in the year 2012. The results indicate that different variables such as crop price variability, water supply source, high-value crops, farm size, income, education, membership in cooperatives have a positive effect and variables such as age and number of plots have a negative impact on the probability of adopting modern water saving technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irrigation" title="irrigation">irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=water" title=" water"> water</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20saving%20technology" title=" water saving technology"> water saving technology</a>, <a href="https://publications.waset.org/abstracts/search?q=scarcity" title=" scarcity"> scarcity</a> </p> <a href="https://publications.waset.org/abstracts/88628/crop-price-variation-and-water-saving-technologies-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88628.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">225</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">233</span> The Correlation between Nasal Resistance and Obligatory Oronasal Switching Point in Non-Athletic Non-Smoking Healthy Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20H.%20Bayat">Amir H.

The aim of this study was to assess the role of anterior nasal resistance as one of the effective factors on this switching. Twelve young, healthy, non-athletic and non-smoker male volunteers with normal BMI were selected after physical examination and participated in exercise protocol, including measurement of the ventilation, work load and oronasal switching point (OSP) during exercise, and anterior rhinomanometry at rest. The protocol was an incremental exercise with 25 watt increase in work load per minute up to OSP occurrence. There was a significant negative correlation between resting total anterior nasal resistance with OSP, work load and ventilation (p<0.05, r= -0.709). Resting total anterior nasal resistance can be considered as an important factor on OSP occurrence. So, the reducing the resistance of nasal passage may increase nasal respiration tolerance for longer time during exercise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anterior%20nasal%20resistance" title="anterior nasal resistance">anterior nasal resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=exercise" title=" exercise"> exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=OSP" title=" OSP"> OSP</a>, <a href="https://publications.waset.org/abstracts/search?q=ventilation" title=" ventilation"> ventilation</a>, <a href="https://publications.waset.org/abstracts/search?q=work%20load" title=" work load"> work load</a> </p> <a href="https://publications.waset.org/abstracts/37968/the-correlation-between-nasal-resistance-and-obligatory-oronasal-switching-point-in-non-athletic-non-smoking-healthy-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37968.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">403</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">232</span> Investigation of Beam Defocusing Impact in Millisecond Laser Drilling for Variable Operational Currents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saad%20Nawaz">Saad Nawaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Yu%20Gang">Yu Gang</a>, <a href="https://publications.waset.org/abstracts/search?q=Baber%20Saeed%20Olakh"> Baber Saeed Olakh</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Bilal%20Awan"> M. Bilal Awan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Owing to its exceptional performance and precision, laser drilling is being widely used in modern manufacturing industries. This experimental study mainly addressed the defocusing of laser beam along with different operational currents. The performance has been evaluated in terms of tapering phenomena, entrance and exit diameters etc. The operational currents have direct influence on laser power which ultimately affected the shape of the drilled hole. Different operational currents in low, medium and high ranges are used for laser drilling of 18CrNi8. Experiment results have depicted that there is an increase in entrance diameter with an increase in defocusing distance. However, the exit diameter first decreases and then increases with respect to increasing defocusing length. The evolution of drilled hole from tapered to straight hole has been explained with defocusing at different levels. The optimum parametric combinations for attaining perfect shape of drilled hole is proposed along with lower heat treatment effects for higher process efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=millisecond%20laser" title="millisecond laser">millisecond laser</a>, <a href="https://publications.waset.org/abstracts/search?q=defocusing%20beam" title=" defocusing beam"> defocusing beam</a>, <a href="https://publications.waset.org/abstracts/search?q=operational%20current" title=" operational current"> operational current</a>, <a href="https://publications.waset.org/abstracts/search?q=keyhole%20profile" title=" keyhole profile"> keyhole profile</a>, <a href="https://publications.waset.org/abstracts/search?q=recast%20layer" title=" recast layer"> recast layer</a> </p> <a href="https://publications.waset.org/abstracts/96126/investigation-of-beam-defocusing-impact-in-millisecond-laser-drilling-for-variable-operational-currents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96126.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">231</span> Naturally Occurring Abietic Acid for Liquid Crystalline Epoxy Curing Agents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rasha%20A.Ibrahim%20El-Ghazawy">Rasha A.Ibrahim El-Ghazawy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20M.%20El-Saeed"> Ashraf M.

Differential scanning calorimetry (DSC) and polarized optical microscope (POM) was used to identify the liquid crystal phase transformation temperatures and texture, respectively. POM micro graphs for both LCCs revealing cholesteric texture. A multifunctional epoxy resin with two abietic acid moieties was also synthesized. Dynamic mechanical (DMA) and thermogravimetric (TGA) analyses show that the fully bio-based cured epoxies by either LCCs possess high glass transition temperature (Tg), high modulus (G`) and improved thermal stability. The chemical structure of the synthesized LCCs and epoxy resin was investigated through FTIR and 1HNMR spectroscopic techniques. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abietic%20acid" title="abietic acid">abietic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20mechanical%20analysis" title=" dynamic mechanical analysis"> dynamic mechanical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20resin" title=" epoxy resin"> epoxy resin</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20crystal" title=" liquid crystal"> liquid crystal</a>, <a href="https://publications.waset.org/abstracts/search?q=thermo%20gravimetric%20analysis" title=" thermo gravimetric analysis "> thermo gravimetric analysis </a> </p> <a href="https://publications.waset.org/abstracts/33613/naturally-occurring-abietic-acid-for-liquid-crystalline-epoxy-curing-agents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33613.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">230</span> An Analytical Survey of Construction Changes: Gaps and Opportunities</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Eshtehardian">Ehsan Eshtehardian</a>, <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Khodaverdi"> Saeed Khodaverdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper surveys the studies on construction change and reveals some of the potential future works. A full-scale investigation of change literature, including change definitions, types, causes and effects, and change management systems, is accomplished to explore some of the coming change trends. It is tried to pick up the critical works in each section to deduct a true timeline of construction changes. The findings show that leaping from best practice guides in late 1990s and generic process models in the early 2000s to very advanced modeling environments in the mid-2000s and the early 2010s have made gaps along with opportunities for change researchers in order to develop some more easy and applicable models. Another finding is that there is a compelling similarity between the change and risk prediction models. Therefore, integrating these two concepts, specifically from proactive management point of view, may lead to a synergy and help project teams avoid rework. Also, the findings show that exploitation of cause-effect relationship models, in order to facilitate the dispute resolutions, seems to be an interesting field for future works. <p
