The forward motion of the ship induces a relative velocity between the ship and the surrounding water that causes a water level depression in which the ship sinks. The problem of ship squat is one among the crucial factors affecting the navigation of ships in restricted waters.

However, with regard to their high expense, we have to take into consideration selecting what type of cranes to be utilized which has been discussed by many researchers. In this research, a proposed technique was created to select the suitable type of crane and the best place for crane erection, in addition to minimum radius for requested crane in order to minimize cost. To fulfill that target, a computer program is designed to numerate these problems, demonstrating an example explaining how to apply program and the result donated the best place. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tower%20crane" title="tower crane">tower crane</a>, <a href="https://publications.waset.org/abstracts/search?q=jib%20length" title=" jib length"> jib length</a>, <a href="https://publications.waset.org/abstracts/search?q=operating%20time" title=" operating time"> operating time</a>, <a href="https://publications.waset.org/abstracts/search?q=location" title=" location"> location</a>, <a href="https://publications.waset.org/abstracts/search?q=feasible%20area" title=" feasible area"> feasible area</a> </p> <a href="https://publications.waset.org/abstracts/51801/establishing-the-optimum-location-of-a-single-tower-crane-using-a-smart-mathematical-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51801.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">72</span> Classification Based on Deep Neural Cellular Automata Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20F.%20Hassan">Yasser F.

While AI has transformed several industries, the construction industry is slowly adopting advanced technologies like AI, introducing new risks that lack critical analysis in the current literature. A comprehensive literature review identified a research gap, highlighting the lack of critical analysis of risks and the need for a framework to measure and mitigate the risks of AI implementation in the construction industry. Consequently, an online survey was conducted with 24 project managers and construction professionals, possessing experience ranging from 1 to 30 years (with an average of 6.38 years), to gather industry perspectives and concerns relating to AI integration. The survey results yielded several significant findings. Firstly, respondents exhibited a moderate level of familiarity (66.67%) with AI technologies, while the industry's readiness for AI deployment and current usage rates remained low at 2.72 out of 5. Secondly, the top-ranked barriers to AI adoption were identified as lack of awareness, insufficient knowledge and skills, data quality concerns, high implementation costs, absence of prior case studies, and the uncertainty of outcomes. Thirdly, the most significant risks associated with AI use in construction were perceived to be a lack of human control (decision-making), accountability, algorithm bias, data security/privacy, and lack of legislation and regulations. Additionally, the participants acknowledged the value of factors such as education, training, organizational support, and communication in facilitating AI integration within the industry. These findings emphasize the necessity for tailored risk assessment frameworks, guidelines, and governance principles to address the identified risks and promote the responsible adoption of AI technologies in the construction sector. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=risk%20management" title="risk management">risk management</a>, <a href="https://publications.waset.org/abstracts/search?q=construction" title=" construction"> construction</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title=" artificial intelligence"> artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a> </p> <a href="https://publications.waset.org/abstracts/186262/safeguarding-the-construction-industry-interrogating-and-mitigating-emerging-risks-from-ai-in-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186262.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">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">70</span> Optimal Sizing and Placement of Distributed Generators for Profit Maximization Using Firefly Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Engy%20Adel%20Mohamed">Engy Adel Mohamed</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Gamal-Eldin%20Hegazy"> Yasser Gamal-Eldin Hegazy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents a firefly based algorithm for optimal sizing and allocation of distributed generators for profit maximization.

In addition, RCA and RAP were incorporated in the same mixes with replacement levels of (1) 20% RCA and 80% RAP; (2) 40% RCA and 60% RAP; (3) 60% RCA and 40% RAP; and (4) 80% RCA and 20% RAP. A comparison between the experimental capacities and the theoretically predicted values according to Eurocode 4 (EC4) was made as well.

On the other hand, DFIG sensitivity to grid disturbances, especially for voltage sags represents the main disadvantage of the equipment. In this paper, a coil is proposed to be integrated within the DFIG converters to improve the overall performance of a DFIG-based wind energy conversion system (WECS). The charging and discharging of the coil are controlled by controlling the duty cycle of the switches of the dc-dc chopper. Simulation results reveal the effectiveness of the proposed topology in improving the overall performance of the WECS system under study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=doubly%20fed%20induction%20generator" title="doubly fed induction generator">doubly fed induction generator</a>, <a href="https://publications.waset.org/abstracts/search?q=coil" title=" coil"> coil</a>, <a href="https://publications.waset.org/abstracts/search?q=wind%20energy%20conversion%20system" title=" wind energy conversion system"> wind energy conversion system</a>, <a href="https://publications.waset.org/abstracts/search?q=converter%20topology" title=" converter topology"> converter topology</a> </p> <a href="https://publications.waset.org/abstracts/28390/a-new-converter-topology-for-wind-energy-conversion-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28390.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">661</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">62</span> Optimal Load Control Strategy in the Presence of Stochastically Dependent Renewable Energy Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20M.%20Othman">Mahmoud M.

The proposed strategy aims to determine the optimal load to be controlled and the corresponding time of control in order to minimize the energy purchased from substation. The presented strategy helps the distribution network operator to rely on the renewable energy sources in supplying the system demand. The renewable energy sources used in the presented study are modeled using the diagonal band Copula method and sequential Monte Carlo method in order to accurately consider the multivariate stochastic dependence between wind power, photovoltaic power and the system demand. The proposed algorithms are implemented in MATLAB environment and tested on the IEEE 37-node feeder. Several case studies are done and the subsequent discussions show the effectiveness of the proposed algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=big%20bang%20big%20crunch" title="big bang big crunch">big bang big crunch</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20generation" title=" distributed generation"> distributed generation</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20control" title=" load control"> load control</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=planning" title=" planning"> planning</a> </p> <a href="https://publications.waset.org/abstracts/44666/optimal-load-control-strategy-in-the-presence-of-stochastically-dependent-renewable-energy-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44666.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">344</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">61</span> Evaluation of Flange Bending Capacity near Member End Using a Finite Element Analysis Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alicia%20Kamischke">Alicia Kamischke</a>, <a href="https://publications.waset.org/abstracts/search?q=Souhail%20Elhouar"> Souhail Elhouar</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Khodair"> Yasser Khodair</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The American Institute of Steel Construction (AISC) Specification (360-10) provides equations for calculating the capacity of a W-shaped steel member to resist concentrated forces applied to its flange. In the case of flange local bending, the capacity equations were primarily formulated for an interior point along the member, which is defined to be at a distance larger than ten flange thicknesses away from the member’s end. When a concentrated load is applied within ten flange thicknesses from the member’s end, AISC requires a fifty percent reduction to be applied to the flange bending capacity. This reduction, however, is not supported by any research. In this study, finite element modeling is used to investigate the actual reduction in capacity near the end of such a steel member. The results indicate that the AISC equation for flange local bending is quite conservative for forces applied at less than ten flange thicknesses from the member’s end and a new equation is suggested for the evaluation of available flange local bending capacity within that distance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flange%20local%20bending" title="flange local bending">flange local bending</a>, <a href="https://publications.waset.org/abstracts/search?q=concentrated%20forces" title=" concentrated forces"> concentrated forces</a>, <a href="https://publications.waset.org/abstracts/search?q=column" title=" column"> column</a>, <a href="https://publications.waset.org/abstracts/search?q=flange%20capacity" title=" flange capacity"> flange capacity</a> </p> <a href="https://publications.waset.org/abstracts/22697/evaluation-of-flange-bending-capacity-near-member-end-using-a-finite-element-analysis-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22697.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">686</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">60</span> Ichnofacies and Microfacies Analysis of Late Eocene Rocks in Fayum Area, Egypt and Their Paleoenvironmental Implications </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheir%20El-Shazly">Soheir El-Shazly</a>, <a href="https://publications.waset.org/abstracts/search?q=Gouda%20Abdelgawad"> Gouda Abdelgawad</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Salama"> Yasser Salama</a>, <a href="https://publications.waset.org/abstracts/search?q=Dina%20Sayed"> Dina Sayed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Abstract- The Late Eocene rocks (Qasr El-Sagha ) Formation, north east of Birket Qarun in Fayum area of Egypt reveals 6 Ichnogenera Thalassinoides Ehrenberg, 1944, Ophiomorpha Lundgren (1891), Skolithos Haldemann (1840), Diplocraterion Torell, 1870, Arenicolites Salter, 1857 and Planolites Nicholson, 1873.

Actual number of alleles, effective number of alleles, gene diversity, Shannon’s information index and polymorphic bands were calculated for each evaluated camel breed. Neighbor-joining tree that re-constructed for evaluated these camel breeds showed that, Hamara breed is distantly related from the other evaluated camels. In addition, the polymorphic sites, haplotypes and nucleotide diversity were identified for some camelidae <em>cox1</em> gene sequences (obtained from NCBI). The distance value between <em>C. bactrianus</em> and <em>C. dromedarius</em> (0.072) was relatively low.

They are quite important in enhancing the quality of urban life while offering social, health, environmental and economic benefits to a city and its residents. Place-making assessment of public urban spaces has been one of the major guiding principles for urban planning and policymaking, of which the definition and evaluation have become the crucial research topic. It is increasingly being essential to mitigate the undesirable impacts of urbanization in cities while improving public urban space’s resilience to environmental, social, and economic changes. Globally, several place-making assessment tools (PATs) have been developed to make such informed decision-making. They act as a catalyst to increase market demand for sustainable products and services by providing a mechanism for recognizing excellence. Assessing how placemaking can positively contribute to urban environments is critical to inform both the continued development of the place and the way placemaking is done as a practice. Therefore, this study aims to review different themes for assessing urban placemaking in public urban spaces. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=urban%20placemaking" title="urban placemaking">urban placemaking</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20urban%20spaces" title=" public urban spaces"> public urban spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=placemaking%20assessment" title=" placemaking assessment"> placemaking assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=literature%20review" title=" literature review"> literature review</a> </p> <a href="https://publications.waset.org/abstracts/164346/a-review-of-urban-placemaking-assessment-frameworks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164346.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">98</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">57</span> Pattern Recognition Based on Simulation of Chemical Senses (SCS)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nermeen%20El%20Kashef">Nermeen El Kashef</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Fouad"> Yasser Fouad</a>, <a href="https://publications.waset.org/abstracts/search?q=Khaled%20Mahar"> Khaled Mahar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> No AI-complete system can model the human brain or behavior, without looking at the totality of the whole situation and incorporating a combination of senses. This paper proposes a Pattern Recognition model based on Simulation of Chemical Senses (SCS) for separation and classification of sign language. The model based on human taste controlling strategy. The main idea of the introduced model is motivated by the facts that the tongue cluster input substance into its basic tastes first, and then the brain recognizes its flavor. To implement this strategy, two level architecture is proposed (this is inspired from taste system). The separation-level of the architecture focuses on hand posture cluster, while the classification-level of the architecture to recognizes the sign language. The efficiency of proposed model is demonstrated experimentally by recognizing American Sign Language (ASL) data set. The recognition accuracy obtained for numbers of ASL is 92.9 percent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=biocybernetics" title=" biocybernetics"> biocybernetics</a>, <a href="https://publications.waset.org/abstracts/search?q=gustatory%20system" title=" gustatory system"> gustatory system</a>, <a href="https://publications.waset.org/abstracts/search?q=sign%20language%20recognition" title=" sign language recognition"> sign language recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=taste%20sense" title=" taste sense"> taste sense</a> </p> <a href="https://publications.waset.org/abstracts/40814/pattern-recognition-based-on-simulation-of-chemical-senses-scs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40814.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">294</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">56</span> Electrochemical Corrosion Behavior of New Developed Titanium Alloys in Ringer’s Solution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20M.%20Abd-elrhman">Yasser M.

Besides other important material features, the corrosion parameters and corrosion products are responsible for limiting the biological and chemical bio compatibility of metallic materials that produce undesirable reactions in implant-adjacent and/or more distant tissues. Electrochemical corrosion behaviors of novel beta titanium alloys, Ti-4.7Mo-4.5Fe, Ti-3Mo-0.5Fe, and Ti-2Mo-0.5Fe were characterized in naturally aerated Ringer’s solution at room temperature compared with common used biomedical titanium alloy, Ti-6Al-4V. The corrosion resistance of titanium alloys were investigated through open circuit potential (OCP), potentiodynamic polarization measurements and optical microscope (OM). A high corrosion resistance was obtained for all alloys due to the stable passive film formed on their surfaces. The new present alloys are promising metallic biomaterials for the future, owing to their very low elastic modulus and good corrosion resistance capabilities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=titanium%20alloys" title="titanium alloys">titanium alloys</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion%20resistance" title=" corrosion resistance"> corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=Ringer%E2%80%99s%20solution" title=" Ringer’s solution"> Ringer’s solution</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20corrosion" title=" electrochemical corrosion"> electrochemical corrosion</a> </p> <a href="https://publications.waset.org/abstracts/19503/electrochemical-corrosion-behavior-of-new-developed-titanium-alloys-in-ringers-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19503.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">658</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">55</span> Urban Heritage and Its Role in the Tourism Development in Yemen: Case Study of Historic Town of Zabid</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20Alhiagi">Yasser Alhiagi</a>, <a href="https://publications.waset.org/abstracts/search?q=Moshalleh%20Almoraekhi"> Moshalleh Almoraekhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sameh%20Refaat"> Sameh Refaat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Urban heritage has an important status in the process of developing the Yemeni tourism sector. Urban heritage in Yemen differs depending on the regions and historical cities such as City of Old Sana'a, Historic Town of Zabid, Shibam Hadhramout, Taiz, and others. Zabid is an old town with a long history, founded in the 9th century. It has been the capital of Yemen from the 13th to the 15th century and played, because of its Islamic university, an important role in the Arab and Muslim world for many centuries. The aim of this research is to promote the built heritage of Historic Town of Zabid and explore the possibilities of visiting the rehabilitated buildings and other heritage attractions through tourism. It examines the nature of the relationship exists between tourism and built heritage. The research is intended to contribute to the strategy development of national tourism for the purpose of protecting, developing, and utilizing cultural heritage.

These units are connected in two different configurations in order to be tested and compared experimentally. In AGMD, the coolant water is used to condensate water vapor leaving membrane via condensing plate. The rejected cooling water has a relativity high temperature which can be used, depending on operation parameters, to increase the thermal efficiency and water productivity. In the first configuration, the seawater feed flows parallel and equally through both units then rejected. The coolant water is divided into the two units, and the heat source is divided into the two heat exchangers. In the second one, only the feed of the first unit is heated while the cooling rejected from the unit is used in heating the feed to the second. The performance of the system, estimated by the water productivity as well as the Gain Output Ratio (GOR), is measured for the two configurations at different feed flow rates, temperatures and salinities.
