platform should consider all service provider's capabilities and tries to integrate services in an equilibrium state. This research develops a framework for implementing manufacturing cloud service composition in the equilibrium state. The developed framework using well-known tools called axiomatic design (AD) and game theory. The research has investigated the factors for forming equilibrium for measures of the manufacturing cloud service composition. Functional requirements (FRs) represent the measures of manufacturing cloud service composition in the equilibrium state. These FRs satisfied by related Design Parameters (DPs). The FRs and DPs are defined by considering the game theory, QoS, consumer needs, parallel and cooperative services. Ultimately, four FRs and DPs represent the framework. To insure the validity of the framework, the authors have used the first AD’s independent axiom. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axiomatic%20design" title="axiomatic design">axiomatic design</a>, <a href="https://publications.waset.org/abstracts/search?q=manufacturing%20cloud%20service%20composition" title=" manufacturing cloud service composition"> manufacturing cloud service composition</a>, <a href="https://publications.waset.org/abstracts/search?q=cloud%20manufacturing" title=" cloud manufacturing"> cloud manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=industry%204.0" title=" industry 4.0"> industry 4.0</a> </p> <a href="https://publications.waset.org/abstracts/113120/using-axiomatic-design-for-developing-a-framework-of-manufacturing-cloud-service-composition-in-the-equilibrium-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113120.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">173</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">137</span> A Framework for Strategy Development in Small Companies: A Case Study of a Telecommunication Firm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Goodarzi">Maryam Goodarzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdieh%20Sheikhi"> Mahdieh Sheikhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Goodarzi"> Mehdi Goodarzi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study intends to offer an appropriate strategy development framework for a telecommunication firm (as a case study) which works on Information and Communication Technology (ICT) projects, development of telecommunication networks, and maintenance of local networks, according to its dominant condition.

When high-energy X-rays are externally applied to treat laryngeal cancer, the absorbed dose at the laryngeal lumen is lower than given dose because of air space which it should pass through before reaching the lesion. Specially in case of high-energy X-rays, the loss of dose is considerable. Three-dimensional absorbed dose distributions have been computed for high-energy photon radiation therapy of laryngeal and hypo pharyngeal cancers, using a coaxial pair of opposing lateral beams in fixed positions.

The MHC plays a central role in the control of disease resistance and immunological response. Genomic DNA from blood samples of 124 sheep was extracted and a 296 bp MHC exon 2 fragment was amplified using polymerase chain reaction. PCR products were characterized by the restriction fragment length polymorphism technique using Hin1I restriction enzyme. The PCRRFLP patterns showed three genotypes, AA, AB and BB with frequency of 0.282, 0.573 and 0.145, respectively. There was no significant (P > 0.05) deviation from Hardy–Weinberg equilibrium for this locus in this population. The results of the present study indicate that exon 2 of the Ovar-DRB1 gene is highly polymorphic in Lori sheep and could be considered as an important marker assisted selection, for improvement of immunity in sheep. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MHC-DRB1%20gene" title="MHC-DRB1 gene">MHC-DRB1 gene</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=PCR-RFLP" title=" PCR-RFLP"> PCR-RFLP</a>, <a href="https://publications.waset.org/abstracts/search?q=lori%20sheep" title=" lori sheep"> lori sheep</a> </p> <a href="https://publications.waset.org/abstracts/46341/mhc-class-ii-drb1-gene-polymorphism-in-lori-sheep-breed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46341.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">420</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">132</span> Disadvantages and Drawbacks of Concrete Blocks and Fix Their Defects</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Sadie">Ehsan Sadie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, the cost of repair and maintenance of structures is very important and by studying the behavior of reinforced concrete structures Will become specified several factors such as : Design and calculation errors, lack of proper implementation of structural changes, the damage caused by the introduction of random loads, concrete corrosion and environmental conditions reduce durability of the structures .

The use of fibers in concrete pavement is one of the effective methods to control and mitigate cracking. This study investigates the effect of the addition of micro and macro polypropylene fibers in different types and volumes and also in combination with the mechanical properties of concrete used in concrete pavements, including compressive strength, splitting tensile strength, modulus of rupture, and average residual strength. The fibers included micro-polypropylene, macro-polypropylene, and hybrid micro and micro polypropylene in different percentages. The results showed that macro polypropylene has the most significant effect on improving the mechanical properties of concrete. Also, the hybrid micro and macro polypropylene fibers increase the mechanical properties of concrete more. It was observed that according to the results of the average residual strength, macro polypropylene fibers alone and together with micro polypropylene fibers could have excellent performance in controlling the sudden formation of cracks and their growth after the formation of cracking which is an essential property in concrete pavements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete%20pavement" title="concrete pavement">concrete pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=macro%20polypropylene%20fibers" title=" macro polypropylene fibers"> macro polypropylene fibers</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20polypropylene%20fibers" title=" micro polypropylene fibers"> micro polypropylene fibers</a> </p> <a href="https://publications.waset.org/abstracts/128419/investigation-of-the-addition-of-macro-and-micro-polypropylene-fibers-on-mechanical-properties-of-concrete-pavement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128419.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">156</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">129</span> Tram Track Deterioration Modeling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Yousefikia">Mohammad Yousefikia</a>, <a href="https://publications.waset.org/abstracts/search?q=Sara%20Moridpour"> Sara Moridpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Mazloumi"> Ehsan Mazloumi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Perceiving track geometry deterioration decisively influences the optimization of track maintenance operations.

We have to focus on the parameters of absorbing materials such as permittivity, permeability, and thickness so that best absorbing according to our necessity can happen. The real and imaginary parts of the relative complex permittivity (ε<sub>r</sub>' and ε<sub>r</sub>") and permeability (µ<sub>r</sub>' and µ<sub>r</sub>") were obtained by simulation. The microwave absorbing property of carbon and Ni(C) is simulated in this study by MATLAB software; the simulation was in the frequency range between 2 to 12 GHz for carbon black (C), and carbon coated nickel (Ni(C)) with different thicknesses. In fact, we draw reflection loss (RL) for C and Ni-C via frequency. We have compared their absorption for 3-mm thickness and predicted for other thicknesses by using of electromagnetic wave transmission theory. The results showed that reflection loss position changes in low frequency with increasing of thickness. We found out that, in all cases, using nanocomposites as absorbance cannot get better results relative to pure nanoparticles. The frequency where absorption is maximum can determine the best choice between nanocomposites and pure nanoparticles. Also, we could find an optimal thickness for long wavelength absorbing in order to utilize them in protecting shields and covering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=absorbing" title="absorbing">absorbing</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon" title=" carbon"> carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20nickel" title=" carbon nickel"> carbon nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=thicknesses" title=" thicknesses"> thicknesses</a> </p> <a href="https://publications.waset.org/abstracts/80056/simulation-of-reflection-loss-for-carbon-and-nickel-carbon-thin-films" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80056.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">186</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">125</span> Measurement of Viscosity and Moisture of Oil in Supradistribution Transformers Using Ultrasonic Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Kadkhodaie">Ehsan Kadkhodaie</a>, <a href="https://publications.waset.org/abstracts/search?q=Shahin%20Parvar"> Shahin Parvar</a>, <a href="https://publications.waset.org/abstracts/search?q=Soroush%20Senemar"> Soroush Senemar</a>, <a href="https://publications.waset.org/abstracts/search?q=Mostafa%20Shriat"> Mostafa Shriat</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolrasoul%20Malekpour"> Abdolrasoul Malekpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The role of oil in supra distribution transformers is so critical and, several standards in determining the quality of oil have been offered.

Here, we introduce a class of fractal-appearing hierarchical metamaterials by replacing the vertices of the original non-hierarchical hexagonal grid with smaller hexagons and iterating this process to achieve higher levels of hierarchy. It has been recently shown that the isotropic in-plane Young's modulus of this hierarchical structure at small deformations becomes 25 times greater than its regular counterpart with the same mass. At large deformations, we find that hierarchy-dependent elastic buckling introduced at relatively early stages of deformation decreases the value of Poisson's ratio as the structure is compressed uniaxially leading to auxeticity (i.e., negative Poisson's ratio) in subsequent stages of deformation. We also show that the topological hierarchical architecture and instability-induced pattern transformations of the structure under compression can be effectively used to tune the propagation of elastic waves within the structure. We find that the hierarchy tends to shift the existing phononic bandgaps (defined as frequency ranges of strong wave attenuation) to lower frequencies while opening up new bandgaps. Deformation is also demonstrated as another mechanism for opening more bandgaps in hierarchical structures. The results provide new insights into the role of structural organization and hierarchy in regulating mechanical properties of materials at both the static and dynamic regimes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cellular%20structures" title="cellular structures">cellular structures</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycombs" title=" honeycombs"> honeycombs</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20structures" title=" hierarchical structures"> hierarchical structures</a>, <a href="https://publications.waset.org/abstracts/search?q=metamaterials" title=" metamaterials"> metamaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=multifunctional%20structures" title=" multifunctional structures"> multifunctional structures</a>, <a href="https://publications.waset.org/abstracts/search?q=phononic%20crystals" title=" phononic crystals"> phononic crystals</a>, <a href="https://publications.waset.org/abstracts/search?q=auxetic%20structures" title=" auxetic structures"> auxetic structures</a> </p> <a href="https://publications.waset.org/abstracts/51508/effects-of-hierarchy-on-poissons-ratio-and-phononic-bandgaps-of-two-dimensional-honeycomb-structures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51508.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">349</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">123</span> Marine Propeller Cavitation Analysis Using BEM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Yari">Ehsan Yari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a numerical study of sheet cavitation has been performed on DTMB4119 and E779A marine propellers with the boundary element method.

The capability of analyzing the wetted and cavitation flow around propellers in steady, unsteady, uniform, and non-uniform conditions while decreasing computational time compared to numerical finite volume methods with acceptable precision are the characteristic features of the present method. Moreover, modifying the position of the detachment point and its corresponding potential value has been considered.

In this study, we aimed to define some normal reference values for meniscal extrusion in the normal knees during different ranges of motion. Methods: The amount of anterior and posterior portion of meniscal extrusion among twenty-one asymptomatic volunteers (42 knees) were tracked at 0, 45, and 90 degrees of knee flexion using an ultrasound machine. The repeated measures analysis of variance (ANOVA) was used to show the interaction between the amounts of meniscal extrusion and the different degrees of knee flexion. Result: The anterior portion of the lateral menisci at full knee extension (0.59±1.40) and the posterior portion of the medial menisci during 90° flexion (3.06±2.36) showed the smallest and the highest mean amount of extrusion, respectively. The normal average amounts of anterior extrusion were 1.12± 1.17 mm and 0.99± 1.34 mm for medial and lateral menisci, respectively. The posterior meniscal normal extrusions were significantly increasing in both medial and lateral menisci during the survey (F= 20.250 and 11.298; both P-values< 0.001) as they were measured at 2.37± 2.16 mm and 1.53± 2.18 mm in order. Conclusion: The medial meniscus can extrude 1.74± 1.84 mm normally, while this amount was 1.26± 1.82 mm for the lateral meniscus. These measures commonly increased with the rising of knee flexion motion. Likewise, the posterior portion showed more extrusion than the anterior portion on both sides.

Besides, the low loss propagation is achieved with less than 2 % of propagation loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3%20dB%20directional%20couplers" title="3 dB directional couplers">3 dB directional couplers</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon-on-insulator" title=" silicon-on-insulator"> silicon-on-insulator</a>, <a href="https://publications.waset.org/abstracts/search?q=symmetrical%20rib%20waveguide" title=" symmetrical rib waveguide"> symmetrical rib waveguide</a>, <a href="https://publications.waset.org/abstracts/search?q=OptiBPM%209" title=" OptiBPM 9 "> OptiBPM 9 </a> </p> <a href="https://publications.waset.org/abstracts/19712/analysis-of-3-db-directional-coupler-based-on-silicon-on-insulator-soi-large-cross-section-rib-waveguide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19712.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">516</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">119</span> Application of Simulation of Discrete Events in Resource Management of Massive Concreting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Amin%20Hamedirad">Mohammad Amin Hamedirad</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Javad%20Vaziri%20Kang%20Olyaei"> Seyed Javad Vaziri Kang Olyaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Project planning and control are one of the most critical issues in the management of construction projects. Traditional methods of project planning and control, such as the critical path method or Gantt chart, are not widely used for planning projects with discrete and repetitive activities, and one of the problems of project managers is planning the implementation process and optimal allocation of its resources. Massive concreting projects is also a project with discrete and repetitive activities. This study uses the concept of simulating discrete events to manage resources, which includes finding the optimal number of resources considering various limitations such as limitations of machinery, equipment, human resources and even technical, time and implementation limitations using analysis of resource consumption rate, project completion time and critical points analysis of the implementation process. For this purpose, the concept of discrete-event simulation has been used to model different stages of implementation. After reviewing the various scenarios, the optimal number of allocations for each resource is finally determined to reach the maximum utilization rate and also to reduce the project completion time or reduce its cost according to the existing constraints. The results showed that with the optimal allocation of resources, the project completion time could be reduced by 90%, and the resulting costs can be reduced by up to 49%. Thus, allocating the optimal number of project resources using this method will reduce its time and cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=simulation" title="simulation">simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=massive%20concreting" title=" massive concreting"> massive concreting</a>, <a href="https://publications.waset.org/abstracts/search?q=discrete%20event%20simulation" title=" discrete event simulation"> discrete event simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20management" title=" resource management"> resource management</a> </p> <a href="https://publications.waset.org/abstracts/128237/application-of-simulation-of-discrete-events-in-resource-management-of-massive-concreting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128237.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">118</span> Teachers’ Stress as a Moderator of the Impact of POMPedaSens on Preschool Children’s Social-Emotional Learning</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Zarra-Nezhad">Maryam Zarra-Nezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Moazami-Goodarzi"> Ali Moazami-Goodarzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Joona%20Muotka"> Joona Muotka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nina%20Sajaniemi"> Nina Sajaniemi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examines the extent to which the impact of a universal intervention program, i.e., POMPedaSens, on children’s early social-emotional learning (SEL) is different depending on early childhood education (ECE) teaches stress at work. The POMPedaSens program aims to promote children’s (5–6-year-olds) SEL by supporting ECE teachers’ engagement and emotional availability. The intervention effectiveness has been monitored using an 8-month randomized controlled trial design with an intervention (IG; 26 teachers and 195 children) and a waiting control group (CG; 36 teachers and 198 children) that provided the data before and after the program implementation. The ECE teachers in the IG are trained to implement the intervention program in their early childhood education and care groups. Latent change score analysis suggests that the program increases children’s prosocial behavior in the IG when teachers show a low level of stress. No significant results were found for the IG regarding a change in antisocial behavior. However, when teachers showed a high level of stress, an increase in prosocial behavior and a decrease in antisocial behavior were only found for children in the CG. The results suggest a promising application of the POMPedaSens program for promoting prosocial behavior in early childhood when teachers have low stress. The intervention will likely need a longer time to display the moderating effect of ECE teachers’ well-being on children’s antisocial behavior change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20childhood" title="early childhood">early childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=social-emotional%20learning" title=" social-emotional learning"> social-emotional learning</a>, <a href="https://publications.waset.org/abstracts/search?q=universal%20intervention%20program" title=" universal intervention program"> universal intervention program</a>, <a href="https://publications.waset.org/abstracts/search?q=professional%20development" title=" professional development"> professional development</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%27%20stress" title=" teachers' stress"> teachers' stress</a> </p> <a href="https://publications.waset.org/abstracts/163180/teachers-stress-as-a-moderator-of-the-impact-of-pompedasens-on-preschool-childrens-social-emotional-learning" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163180.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">89</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">117</span> Comparing Community Detection Algorithms in Bipartite Networks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Khademi">Ehsan Khademi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Jalili"> Mahdi Jalili</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the special features of bipartite networks, they are common in many systems. Real-world bipartite networks may show community structure, similar to what one can find in one-mode networks. However, the interpretation of the community structure in bipartite networks is different as compared to one-mode networks. In this manuscript, we compare a number of available methods that are frequently used to discover community structure of bipartite networks. These networks are categorized into two broad classes. One class is the methods that, first, transfer the network into a one-mode network, and then apply community detection algorithms. The other class is the algorithms that have been developed specifically for bipartite networks. These algorithms are applied on a model network with prescribed community structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20detection" title="community detection">community detection</a>, <a href="https://publications.waset.org/abstracts/search?q=bipartite%20networks" title=" bipartite networks"> bipartite networks</a>, <a href="https://publications.waset.org/abstracts/search?q=co-clustering" title=" co-clustering"> co-clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=modularity" title=" modularity"> modularity</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20projection" title=" network projection"> network projection</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20networks" title=" complex networks"> complex networks</a> </p> <a href="https://publications.waset.org/abstracts/14451/comparing-community-detection-algorithms-in-bipartite-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14451.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">625</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">116</span> Implementing Internet of Things through Building Information Modelling in Order to Assist with the Maintenance Stage of Commercial Buildings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ushir%20Daya">Ushir Daya</a>, <a href="https://publications.waset.org/abstracts/search?q=Zenadene%20Lazarus"> Zenadene Lazarus</a>, <a href="https://publications.waset.org/abstracts/search?q=Dimelle%20Moodley"> Dimelle Moodley</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Saghatforoush"> Ehsan Saghatforoush</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It was found through literature that there is a lack of implementation of the Internet of Things (IoT) incorporated into Building Information Modelling (BIM) in South Africa.

Basically, this high step-up DC/DC converter is an appealing interface for solar applications. The proposed topology takes advantage of using coupled inductors. Due to the leakage inductances of these coupled inductors, the power MOSFET has the zero current switching (ZCS) condition, which results in decreased switching losses. This will substantially improve the overall efficiency of the power converter. Furthermore, employing coupled inductors has led to a higher voltage gain.

So, for understanding the innate immunity insects can be good models. They are cheap; reproduction is fast and in the case genetics, less complicated. In this review, we tried to briefly tackle with important factors in insects’ innate immunity such as melanization, encapsulation, JAK-STAT, IMD, and Toll pathways. At the end, we explained how hormones and nerve system also can impact on immune system and make it more beautiful. In concluding remarks, the possibility of taking help from insect immune system to fight against diseases such as cancer has been considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=insects" title="insects">insects</a>, <a href="https://publications.waset.org/abstracts/search?q=innate%20immunity" title=" innate immunity"> innate immunity</a>, <a href="https://publications.waset.org/abstracts/search?q=melanization" title=" melanization"> melanization</a>, <a href="https://publications.waset.org/abstracts/search?q=intracellular%20pathways" title=" intracellular pathways"> intracellular pathways</a>, <a href="https://publications.waset.org/abstracts/search?q=hormones" title=" hormones"> hormones</a> </p> <a href="https://publications.waset.org/abstracts/74600/innate-immunity-of-insects-in-brief" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74600.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">226</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">112</span> Buckling Analysis of 2D Frames Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose of this paper is to present the Modified Newmark Method of buckling analysis frame considering the effect of the axial load.

An energy source that can have the necessary reliability, be a suitable alternative to fossil fuels, be technologically achievable, comply with environmental standards to the maximum, and at the same time cause countries to meet domestic consumption for electricity production. Iran is one of the richest countries in the world in terms of various energy sources because, on the one hand, it has extensive sources of fossil and non-renewable fuels such as oil and gas, and on the other hand, it has great potential for renewable energy.

Radon exposure risks are a function of geologic, geographic, design, and human behavioural variables and can change over time. Using time series and deep machine learning modelling, we analyzed long-term radon test outcomes as a function of building metrics from 25,489 Canadian and 38,596 Swedish residential properties constructed between 1945 to 2020. While Canadian and Swedish properties built between 1970 and 1980 are comparable (96–103 Bq/m³), innate radon risks subsequently diverge, rising in Canada and falling in Sweden such that 21st Century Canadian houses show 467% greater average radon (131 Bq/m³) relative to Swedish equivalents (28 Bq/m³). These trends are consistent across housing types and regions within each country. The introduction of energy efficiency measures within Canadian and Swedish building codes coincided with opposing radon level trajectories in each nation. Deep machine learning modelling predicts that, without intervention, average Canadian residential radon levels will increase to 176 Bq/m³ by 2050, emphasizing the importance and urgency of future building code intervention to achieve systemic radon reduction in Canada. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radon%20health%20risk" title="radon health risk">radon health risk</a>, <a href="https://publications.waset.org/abstracts/search?q=time-series" title=" time-series"> time-series</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20machine%20learning" title=" deep machine learning"> deep machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title=" lung cancer"> lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Canada" title=" Canada"> Canada</a>, <a href="https://publications.waset.org/abstracts/search?q=Sweden" title=" Sweden"> Sweden</a> </p> <a href="https://publications.waset.org/abstracts/161187/a-comparative-time-series-analysis-and-deep-learning-projection-of-innate-radon-gas-risk-in-canadian-and-swedish-residential-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161187.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">85</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">109</span> Analytical Study on Threats to Wetland Ecosystems and Their Solutions in the Framework of the Ramsar Convention</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Daryadel">Ehsan Daryadel</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhad%20Talaie"> Farhad Talaie </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wetlands are one of the most important ecosystems on Earth. Nevertheless, various challenges threaten these ecosystems and disrupt their ecological character. Among these, the effects of human-based threats are more devastating. Following mass degradation of wetlands during 1970s, the Ramsar Convention on Wetlands (Ramsar, Iran, 1971) was concluded to conserve wetlands of international importance and prevent destruction and degradation of such ecosystems through wise use of wetlands as a mean to achieve sustainable development in all over the world. Therefore, in this paper, efforts have been made to analyze threats to wetlands and then investigate solutions in the framework of the Ramsar Convention. Finally, in order to operate these mechanisms, this study concludes that all states should in turn make their best effort to improve and restore global wetlands through preservation of environmental standards and close contribution and also through taking joint measures with other states effectively. <p class="card-text"><strong>Keywords:</strong> <a
