Materials & Methods: This study aims to verify the concentrations and sources of heavy metals for surface samples containing randomly taken soil. Chemical analyses were performed using iCAP 7000 Series ICP-optical emission spectrometer, using a set of environmental quality indicators by calculating the enrichment factor using iron and aluminum references, geographic accumulation index and geographic information system (GIS). On the basis of the spatial distribution. Results: The results indicated that the average metal concentration was: (As = 30,82),(Pb = 1219,27), (Zn = 2855,94), (Cu = 5,3), mg/Kg,based on these results, all metals except Cu passed by GBV in the Earth's crust. Environmental quality indicators were calculated based on the concentrations of trace metals such as lead, arsenic, zinc, copper, iron and aluminum. Interpretation: This study investigated the concentrations and sources of trace metals, and by using quality indicators and statistical methods, lead, zinc, and arsenic were determined from human sources, while copper was a natural source. And based on the spatial analysis on the basis of GIS, many hot spots were identified in the El-Abed region. Conclusion: These results could help in the development of future treatment strategies aimed primarily at eliminating materials from mining waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20contamination" title="soil contamination">soil contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title=" trace metals"> trace metals</a>, <a href="https://publications.waset.org/abstracts/search?q=geochemical%20indices" title=" geochemical indices"> geochemical indices</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Abed%20mine" title=" El Abed mine"> El Abed mine</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/178017/risk-assessment-of-trace-metals-in-the-soil-surface-of-an-abandoned-mine-el-abed-northwestern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178017.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">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">45</span> Wadi Halfa Oolitic Ironstone Formation, Wadi Halfa and Argein Areas, North Sudan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mutwakil%20Nafi">Mutwakil Nafi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abed%20Elaziz%20El%20Amein"> Abed Elaziz El Amein</a>, <a href="https://publications.waset.org/abstracts/search?q=Muna%20El%20Dawi"> Muna El Dawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Khalafala%20Salih"> Khalafala Salih</a>, <a href="https://publications.waset.org/abstracts/search?q=Osma%20Elbahi"> Osma Elbahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Abed%20Elhalim%20Abou"> Abed Elhalim Abou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently a large deposit of oolitic iron ore of Late Carboniferous-Permotriassic-Lower Jurassic age was discovered in Wadi Halfa and Argein areas, North Sudan. It seems that the iron ore mineralization exists in the west and east bank of the River Nile of the study area that are found on the Egyptian-Sudanese border. The Carboniferous-Lower Jurassic age strata were covered by 67 sections and each section has been examined and carefully described. The iron-ore in Wadi Halfa occurs as oolitic ironstone and contained two horizons: (A) horizon and (B) horizon. Only horizon (A) was observed in southern Argein area. The texture of the ore is variable depending on the volume of the component. In thin sections the average of the ooids were ranged between 90% - 80%. The matrix varies between 10%-20% by volume and detritus quartz in other component my reach up to 30% by volume in sandy massive ore. Ooids size ranges from 0.2mm-1.00 mm on average in very coarse ooids may attend up to 1 mm in size. The matrix around the ooids is dominated by iron hydroxide, carbonate, fine and amorphous silica. The probable ore reserve estimate of 1.234 billion at a head grade of 41.29% Fe for the Wadi Halfa Oolitic Ironstone Formation. The iron ore shows higher content of phosphorus ranges from 6.15% to 0.16%, with mean 1.45%. The new technology Hatch–Ironstone Chloride Segregation (HICS) can be used to produce commercial-quality of iron and reduce phosphorus and silica to acceptable levels for steel industry. The development of infra structures and presence huge quantity of iron ore would make exploitation of the iron ore economic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HICS" title="HICS">HICS</a>, <a href="https://publications.waset.org/abstracts/search?q=Late%20Carboniferous%20age" title=" Late Carboniferous age"> Late Carboniferous age</a>, <a href="https://publications.waset.org/abstracts/search?q=oolitic%20iron%20ore" title=" oolitic iron ore"> oolitic iron ore</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a> </p> <a href="https://publications.waset.org/abstracts/29727/wadi-halfa-oolitic-ironstone-formation-wadi-halfa-and-argein-areas-north-sudan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29727.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">647</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">44</span> Comparison of Phynotypic Traits of Three Arabian Horse Strains</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saria%20Almarzook">Saria Almarzook</a>, <a href="https://publications.waset.org/abstracts/search?q=Monika%20Reissmann"> Monika Reissmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Gudrun%20Brockmann"> Gudrun Brockmann</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to its history, occurrence in different ecosystems and diverse using, the modern horse (Equus caballus) shows large variability in size, appearance, behavior and habits. At all times, breeders try to create groups (breeds, strains) representing high homology but showing clear differences in comparison to other groups. A great interest of analyzing phenotypic and genetic traits looking for real diversity and genetic uniqueness existents for Arabian horses in Syria. 90 Arabian horses from governmental research center of Arabian horses in Damascus were included. The horses represent three strains (Kahlawi, Saklawi, Hamdani) originated from different geographical zones. They were raised on the same farm, under stable conditions. Twelve phenotypic traits were measured: wither height (WH), croup width (CW), croup height (CH), neck girth (NG), thorax girth (TG), chest girth (ChG), chest depth (ChD), chest width (ChW), back line length (BLL), body length (BL), fore cannon length (FCL) and hind cannon length (HCL). The horses were divided into groups according to age (less than 2 years, 2-4 years, 4-9 years, over 9 years) and to sex (male, female). The statistical analyzes show that age has significant influence of WH while the strain has only a very limited effect. On CW, NG, BLL, FCL and HCL, there is only a significant influence of sex. Age has significant effect on CH and BL. All sources of classes have a significant effect on TG, ChG, ChD and ChW. Strain has a significant effect on the BL. These results provide first information for real biodiversity in and between the strains and can be used to develop the breeding work in the Arabian horse breed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arabian%20horse" title="Arabian horse">Arabian horse</a>, <a href="https://publications.waset.org/abstracts/search?q=phenotypic%20traits" title=" phenotypic traits"> phenotypic traits</a>, <a href="https://publications.waset.org/abstracts/search?q=strains" title=" strains"> strains</a>, <a href="https://publications.waset.org/abstracts/search?q=Syria" title=" Syria"> Syria</a> </p> <a href="https://publications.waset.org/abstracts/28063/comparison-of-phynotypic-traits-of-three-arabian-horse-strains" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28063.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">391</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">43</span> On Chromaticity of Wheels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zainab%20Yasir%20Abed%20Al-Rekaby">Zainab Yasir Abed Al-Rekaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Jalil%20M.%20Khalaf"> Abdul Jalil M.

By inserting the BaF2 as antireflection with the dominant size of 10 nm to fill the space between the shells of wires on the Si (111) substrate. The absorption is significantly improved due to the strong reabsorption of light reflected at the shells and compared with the reference cells. The present simulation leads to a higher absorption efficiency (Qabs) and reaches a value of 97%, and the external quantum efficiencies (EQEs) above 92% are observed. The current density (Jsc) increases by 0.22 mA/cm2 and the open-circuit voltage (Voc) is enhanced by 0.11 mV. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanowire%20solar%20cells" title="nanowire solar cells">nanowire solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption%20efficiency" title=" absorption efficiency"> absorption efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=band%20structures" title=" band structures"> band structures</a>, <a href="https://publications.waset.org/abstracts/search?q=fdtd%20simulation" title=" fdtd simulation"> fdtd simulation</a> </p> <a href="https://publications.waset.org/abstracts/167993/enhancement-in-the-absorption-efficiency-of-gaasinas-nanowire-solar-cells-through-a-decrease-in-light-reflection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/167993.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">73</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">38</span> Keyframe Extraction Using Face Quality Assessment and Convolution Neural Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rahma%20Abed">Rahma Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahbi%20Bahroun"> Sahbi Bahroun</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezzeddine%20Zagrouba"> Ezzeddine Zagrouba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Due to the huge amount of data in videos, extracting the relevant frames became a necessity and an essential step prior to performing face recognition. In this context, we propose a method for extracting keyframes from videos based on face quality and deep learning for a face recognition task. This method has two steps. We start by generating face quality scores for each face image based on the use of three face feature extractors, including Gabor, LBP, and HOG. The second step consists in training a Deep Convolutional Neural Network in a supervised manner in order to select the frames that have the best face quality. The obtained results show the effectiveness of the proposed method compared to the methods of the state of the art. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=keyframe%20extraction" title="keyframe extraction">keyframe extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20quality%20assessment" title=" face quality assessment"> face quality assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=face%20in%20video%20recognition" title=" face in video recognition"> face in video recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=convolution%20neural%20network" title=" convolution neural network"> convolution neural network</a> </p> <a href="https://publications.waset.org/abstracts/111347/keyframe-extraction-using-face-quality-assessment-and-convolution-neural-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111347.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">233</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">37</span> Behavior of Square Reinforced-Concrete Columns Strenghtened with Carbon Fiber Reinforced Polymers (CFRP) under Concentric Loading</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dana%20Abed">Dana Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mu%60Tasim%20Abdel-Jaber"> Mu`Tasim Abdel-Jaber</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Shatarat"> Nasim Shatarat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aims at investigating the influence of cross-sectional size on axial compressive capacity of carbon fiber reinforced polymer (CFRP) wrapped square reinforced concrete short columns.

Consistency, compressive strength, bending strength and the activity index of WCCP through seven to ninety days old specimens have been examined, where the optimum WCCP replacement was up to 30%, depending on which the activity index still increased to the end of test period (90 days) and this could be an evidence for its continuity to increase for longer age. Also up to 30% of WCCP increased the bending strength to be higher than the control one.

The procedure, applied to identify the parameters of generalized Prager model associated to the Drucker & Prager failure criterion from a pressuremeter expansion curve, is based on an inverse analysis approach, which consists of minimizing the function representing the difference between the experimental curve and the simulated curve using a simplex algorithm. The model response on pressuremeter path and its identification from experimental data lead to the determination of the friction angle, the cohesion and the Young modulus. Some parameters effects on the simulated curves and stresses path around pressuremeter probe are presented.

Fuzzy Vulnerability uses a fuzzy representation in order to tolerate the imprecision during the description of construction. At the the second phase, we evaluated the similarity between the vulnerability of a new construction and those of the whole of the historical cases. This similarity is evaluated on two levels: 1) individual similarity: bases on the fuzzy techniques of aggregation; 2) Global similarity: uses the increasing monotonous linguistic quantifiers (RIM) to combine the various individual similarities between two constructions. The third phase of the process of Fuzzy Vulnerability consists in using vulnerabilities of historical constructions narrowly similar to current construction to deduce its estimate vulnerability. We validated our system by using 50 cases. We evaluated the performances of Fuzzy Vulnerability on the basis of two basic criteria, the precision of the estimates and the tolerance of the imprecision along the process of estimation. The comparison was done with estimates made by tiresome and long models. The results are satisfactory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=case%20based%20reasoning" title="case based reasoning">case based reasoning</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20logic" title=" fuzzy logic"> fuzzy logic</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20case%20based%20reasoning" title=" fuzzy case based reasoning"> fuzzy case based reasoning</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20vulnerability" title=" seismic vulnerability"> seismic vulnerability</a> </p> <a href="https://publications.waset.org/abstracts/11237/integration-of-fuzzy-logic-in-the-representation-of-knowledge-application-in-the-building-domain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11237.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">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Residual Modulus of Elasticity of Self-Compacting Concrete Incorporated Unprocessed Waste Fly Ash after Expose to the Elevated Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Abed">Mohammed Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Nemes"> Rita Nemes</a>, <a href="https://publications.waset.org/abstracts/search?q=Salem%20Nehme"> Salem Nehme</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study experimentally investigated the impact of incorporating unprocessed waste fly ash (UWFA) on the residual mechanical properties of self-compacting concrete (SCC) after exposure to elevated temperature. Three mixtures of SCC have been produced by replacing the cement mass by 0%, 15% and 30% of UWFA. Generally, the fire resistance of SCC has been enhanced by replacing the cement up to 15% of UWFA, especially in case of residual modulus of elasticity which considers more sensitive than other mechanical properties at elevated temperature. However, a strong linear relationship has been observed between the residual flexural strength and modulus of elasticity, where both of them affected significantly by the cracks appearance and propagation as a result of elevated temperature. Sustainable products could be produced by incorporating unprocessed waste powder materials in the production of concrete, where the waste materials, CO<sub>2</sub> emissions, and the energy needed for processing are reduced. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=self-compacting%20high-performance%20concrete" title="self-compacting high-performance concrete">self-compacting high-performance concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=unprocessed%20waste%20fly%20ash" title=" unprocessed waste fly ash"> unprocessed waste fly ash</a>, <a href="https://publications.waset.org/abstracts/search?q=fire%20resistance" title=" fire resistance"> fire resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=residual%20modulus%20of%20elasticity" title=" residual modulus of elasticity"> residual modulus of elasticity</a> </p> <a href="https://publications.waset.org/abstracts/111302/residual-modulus-of-elasticity-of-self-compacting-concrete-incorporated-unprocessed-waste-fly-ash-after-expose-to-the-elevated-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111302.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">135</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">28</span> Enhancement in the Absorption Efficiency of GaAs/InAs Nanowire Solar Cells through a Decrease in Light Reflection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latef%20M.%20Ali">Latef M.

By inserting the BaF2 as antireflection with the dominant size of 10 nm to fill the space between the shells of wires on the Si (111) substrate. The absorption is significantly improved due to the strong reabsorption of light reflected at the shells and compared with the reference cells. The present simulation leads to a higher absorption efficiency (Qabs) and reaches a value of 97%, and the external quantum efficiencies (EQEs) above 92% are observed. The current density (Jsc) increases by 0.22 mA/cm2 and the open-circuit voltage (Voc) is enhanced by 0.11 mV. it explore the design and optimization of high-efficiency solar cells on low-reflective absorption efficiency of GaAs/InAs using simulation software tool. The changes in the core and shell diameters profoundly affects the generation and recombination process, thus affecting the conversion efficiency of solar cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanowire%20solar%20cells" title="nanowire solar cells">nanowire solar cells</a>, <a href="https://publications.waset.org/abstracts/search?q=absorption%20efficiency" title=" absorption efficiency"> absorption efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=photovoltaic" title=" photovoltaic"> photovoltaic</a>, <a href="https://publications.waset.org/abstracts/search?q=band%20structures" title=" band structures"> band structures</a>, <a href="https://publications.waset.org/abstracts/search?q=FDTD%20simulation" title=" FDTD simulation"> FDTD simulation</a> </p> <a href="https://publications.waset.org/abstracts/182969/enhancement-in-the-absorption-efficiency-of-gaasinas-nanowire-solar-cells-through-a-decrease-in-light-reflection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182969.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">49</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">27</span> The Knowledge and Beliefs Concerning Attention Deficit Hyperactivity Disorder Held by Parents of Children With Attention Deficit Hyperactivity Disorder in Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohaned%20G.%20Abed">Mohaned G.

It has an effect on 3–5% of school-aged children, and brings about difficulties in academic and social interaction. This study explored the knowledge and beliefs of parents in Saudi Arabia about children with ADHD. The Knowledge about Attention Deficit Disorder Questionnaire (KADD-Q) was administered to a sample of parents, followed by interviews with a subset of the total respondents. The results indicated that the parents knew more about the characteristics of ADHD than they knew about its related causes and treatment. Overall, the findings indicated that these parents had some knowledge about general characteristics of ADHD, but they had little understanding of causes and possible interventions. These results suggest an important need for more formal parents training regarding all aspects of ADHD in school age children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attention%20deficit%20hyperactivity%20disorder" title="attention deficit hyperactivity disorder">attention deficit hyperactivity disorder</a>, <a href="https://publications.waset.org/abstracts/search?q=childhood%20disorders" title=" childhood disorders"> childhood disorders</a>, <a href="https://publications.waset.org/abstracts/search?q=school-aged%20children" title=" school-aged children"> school-aged children</a>, <a href="https://publications.waset.org/abstracts/search?q=difficulties%20in%20academic" title=" difficulties in academic"> difficulties in academic</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20interaction" title=" social interaction"> social interaction</a> </p> <a href="https://publications.waset.org/abstracts/152120/the-knowledge-and-beliefs-concerning-attention-deficit-hyperactivity-disorder-held-by-parents-of-children-with-attention-deficit-hyperactivity-disorder-in-saudi-arabia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152120.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">112</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">26</span> Characteristics of Different Volumes of Waste Cellular Concrete Powder-Cement Paste for Sustainable Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Abed">Mohammed Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rita%20Nemes"> Rita Nemes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cellular concrete powder (CCP) is not used widely as supplementary cementitious material, but in the literature, its efficiency is proved when it used as a replacement of cement in concrete mixtures.

It is an attempt to produce green binder paste, which is useful for sustainable construction applications. The fresh and hardened properties of a number of CCP blended cement paste will be tested in different life periods, and the optimized CCP volume will be reported with more significant investigations on durability properties. Different replacing of mass percentage (low and high) of the cement mass will be conducted (0%, 10%, 15%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90%).

Both feedstocks were previously mechanically pretreated in order to reduce their particle size. Methane potential assays were carried out at laboratory scale in batch mode for 28 days. The study was planned according to two factors: the feedstock to inoculum (F/I) ratio and the waste paper to macroalgae (WP/MA) ratio. The F/I ratios checked were 0.2, 0.3 and 0.4 and the WP/MA ratios were 0:100, 25:75, 50:50, 75:25 and 100:0. The highest methane yield (608 ml/g of volatile solids (VS)) was achieved at an F/I ratio of 0.2 and a WP/MA ratio of 50:50. The methane yield at a ratio WP/MA of 50:50 is higher than for single compound, while for ratios WP/MA of 25:75 and 75:25 the methane yield decreases compared to biomass mono-digestion. This behavior is observed for the three levels of F/I ratio being more noticeable at F/I ratio of 0.3. A synergistic effect was found for the WP/MA ratio of 50:50 and all F/I ratios and for WP/MA=50:50 and F/I=0.2. A maximum increase of methane yield of 49.58% was found for a co-digestion ratio of 50:50 and an F/I ratio of 0.4. It was concluded that methane production from waste paper improves significantly when co-digested with macroalgae biomass. The methane yields from co-digestion were also found higher that from macroalgae mono-digestion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anaerobic%20co-digestion" title="anaerobic co-digestion">anaerobic co-digestion</a>, <a href="https://publications.waset.org/abstracts/search?q=biogas" title=" biogas"> biogas</a>, <a href="https://publications.waset.org/abstracts/search?q=macroalgae" title=" macroalgae"> macroalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20paper" title=" waste paper"> waste paper</a> </p> <a href="https://publications.waset.org/abstracts/64720/enhanced-methane-production-from-waste-paper-through-anaerobic-co-digestion-with-macroalgae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64720.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">367</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">24</span> Predictive Analysis for Big Data: Extension of Classification and Regression Trees Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ameur%20Abdelkader">Ameur Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Abed%20Bouarfa%20Hafida"> Abed Bouarfa Hafida</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Since its inception, predictive analysis has revolutionized the IT industry through its robustness and decision-making facilities. It involves the application of a set of data processing techniques and algorithms in order to create predictive models. Its principle is based on finding relationships between explanatory variables and the predicted variables. Past occurrences are exploited to predict and to derive the unknown outcome. With the advent of big data, many studies have suggested the use of predictive analytics in order to process and analyze big data. Nevertheless, they have been curbed by the limits of classical methods of predictive analysis in case of a large amount of data. In fact, because of their volumes, their nature (semi or unstructured) and their variety, it is impossible to analyze efficiently big data via classical methods of predictive analysis. The authors attribute this weakness to the fact that predictive analysis algorithms do not allow the parallelization and distribution of calculation. In this paper, we propose to extend the predictive analysis algorithm, Classification And Regression Trees (CART), in order to adapt it for big data analysis. The major changes of this algorithm are presented and then a version of the extended algorithm is defined in order to make it applicable for a huge quantity of data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=predictive%20analysis" title="predictive analysis">predictive analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data" title=" big data"> big data</a>, <a href="https://publications.waset.org/abstracts/search?q=predictive%20analysis%20algorithms" title=" predictive analysis algorithms"> predictive analysis algorithms</a>, <a href="https://publications.waset.org/abstracts/search?q=CART%20algorithm" title=" CART algorithm"> CART algorithm</a> </p> <a href="https://publications.waset.org/abstracts/101647/predictive-analysis-for-big-data-extension-of-classification-and-regression-trees-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/101647.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">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Establishment of Kinetic Zone Diagrams via Simulated Linear Sweep Voltammograms for Soluble-Insoluble Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Imene%20Atek">Imene Atek</a>, <a href="https://publications.waset.org/abstracts/search?q=Abed%20M.%20Affoune"> Abed M.

A rigorous analysis of simulated linear scan voltammetric responses following variation of dimensionless factors, the rate constant and charge transfer coefficients in a broad range was studied and presented in the form of the so called kinetic zones diagrams. These kinetic diagrams were divided into three kinetics zones.

In HVAC systems, the jet impingement, in some cases, generates noise that destroys acoustic comfort. This paper presents an experimental study of a rectangular air jet impinging on a slotted plate to investigate the correlation between sound emission and turbulence dynamics. The experiment was conducted with an impact ratio L/H = 4 and a Reynolds number Re = 4700. The survey shows that coherent structures within the impinging jet are responsible for self-sustaining tone production. To achieve this, a specific experimental setup consisting of two simultaneous Stereoscopic Particle Image Velocimetry (S-PIV) measurements was developed to track vortical structures both before and after the plate, in addition to acoustic measurements. The results reveal a significant correlation between acoustic waves and the passage of coherent structures. Variations in the arrangement of vortical structures between the upstream and downstream sides of the plate were observed. This analysis of flow dynamics can enhance our understanding of slot noise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impinging%20jet" title="impinging jet">impinging jet</a>, <a href="https://publications.waset.org/abstracts/search?q=coherent%20structures" title=" coherent structures"> coherent structures</a>, <a href="https://publications.waset.org/abstracts/search?q=SPIV" title=" SPIV"> SPIV</a>, <a href="https://publications.waset.org/abstracts/search?q=aeroacoustics" title=" aeroacoustics"> aeroacoustics</a> </p> <a href="https://publications.waset.org/abstracts/172777/experimental-investigation-of-the-aeroacoustics-field-for-a-rectangular-jet-impinging-on-a-slotted-plate-stereoscopic-particle-image-velocimetry-measurement-before-and-after-the-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/172777.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">83</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">20</span> On the Stability Exact Analysis of Tall Buildings with Outrigger System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahrooz%20Abed">Mahrooz Abed</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20R.%20Masoodi"> Amir R.

Some efficient structures for drift control and base moment reduction in tall buildings is outrigger and belt truss systems. When adopting outrigger beams in building design, their location should be in an optimum position for an economical design. A range of different strategies has been employed to identify the optimum locations of these outrigger beams under wind load. However, there is an absence of scientific research or case studies dealing with optimum outrigger location using buckling analysis. In this paper, one outrigger system is considered at the middle of height of structure. The optimum location of outrigger will be found based on the buckling load limitation. The core of structure is modeled by a clamped tapered beam. The exact stiffness matrix of tapered beam is formulated based on the Euler-Bernoulli theory. Finally, based on the buckling load of structure, the optimal location of outrigger will be found. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tall%20buildings" title="tall buildings">tall buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=outrigger%20system" title=" outrigger system"> outrigger system</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling%20load" title=" buckling load"> buckling load</a>, <a href="https://publications.waset.org/abstracts/search?q=second-order%20effects" title=" second-order effects"> second-order effects</a>, <a href="https://publications.waset.org/abstracts/search?q=Euler-Bernoulli%20beam%20theory" title=" Euler-Bernoulli beam theory"> Euler-Bernoulli beam theory</a> </p> <a href="https://publications.waset.org/abstracts/34858/on-the-stability-exact-analysis-of-tall-buildings-with-outrigger-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34858.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">396</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19</span> Nurses’ Views on ‘Effective Nurse Leader’ Characteristics in Iraq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Abed">S.

It is well established that the provision of modern health care requires effective nurse leaders, but in countries such as Iraq the lack of effective nurse leaders is noted as a major challenge. In a descriptive quantitative study, a survey questionnaire was administered to 210 ward nurses working in two public hospitals in a major city in the north of Iraq. The participating nurses were of the opinion that the effectiveness of their nurse leaders was evident in their ability to demonstrate: good clinical knowledge, effective communication and managerial skills. They also viewed their leaders as needing to hold high-level nursing qualifications, though this was not necessarily the case in practice. Additionally, they viewed nurse leaders’ personal qualities as important, which included politeness, ethical behaviour, and trustworthiness. When considered against the issues raised in interviews with a smaller group (20) of senior nurse leaders, representative of the various occupational levels, implications identify the need for professional development that focuses on how the underpinning competencies relate to leadership and how transformational leadership is evidenced in practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=health%20care" title="health care">health care</a>, <a href="https://publications.waset.org/abstracts/search?q=nurse%20education" title=" nurse education"> nurse education</a>, <a href="https://publications.waset.org/abstracts/search?q=nursing%20in%20Iraq" title=" nursing in Iraq"> nursing in Iraq</a>, <a href="https://publications.waset.org/abstracts/search?q=nurse%20leadership" title=" nurse leadership"> nurse leadership</a> </p> <a href="https://publications.waset.org/abstracts/72508/nurses-views-on-effective-nurse-leader-characteristics-in-iraq" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72508.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">275</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">18</span> Examining the Function of Containers and Determining Lexical Indices for the Shapes of Pottery and the Poems Written on Them from the End of the 3rd Century to the End of the 8th Century</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohadese%20Sookhtesaraii">Mohadese Sookhtesaraii</a>, <a href="https://publications.waset.org/abstracts/search?q=Abed%20Taghavi"> Abed Taghavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Kosar%20Sookhtesaraii"> Kosar Sookhtesaraii</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pottery is always attended by human beings for its application functions. By passing time and human development and writing progressing, writing was started to do on pottery dishes. Some of important issues in making thise dishes, in addition to their application, are their names and obviosely their relationship between their function and their names. These names are different based on their appearances and the kind of their using. So by meaning these words in dictionary, naming these dishes are classified. In poetry works there are so many names of these dishes which are showing their importance and their using. More using of some of these dishes name in poem and writing works is caused the select these dishes. For better and precise analysing the form of pottery it emphasis on the meaning which are in dictionary and the names that are existed in poems and writters works. On the other hand, on the dishes there are written poet more than text, that it can study their beautiful aspect. Seperate from their meanings. Dishes name like Chamaneh, Satgini, was clearly named for drinking in dictionary. while using Khonb was applied for storing. So dishes applying can be the basis of classifying. The size and capacity of these dishes is also caused the differences in naming the dishes. Such as Khom, Khonb which are same in farm but. They are different in capacity and size.
