This criterion is based on maximum strain energy release rate and material nonlinearity in the vicinity of crack tip due to presence of microcracks.

The crack is subjected along the fibers at plane strain conditions. Despite the complicities to solve the nonlinear equations which are requirements of SED criterion, SED criterion for anisotropic materials is derived. In the present research, fracture limit curve of SED criterion is depicted by a numerical solution, hence the direction of crack growth is figured out by derived criterion, MSED. The validated MSED demonstrates the improvement in prediction of fracture behavior of the materials. Also, damaged factor that plays a crucial role in the fracture behavior of quasi-brittle materials is derived from this criterion and proved its dependency on mechanical properties and direction of crack growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mixed-mode%20fracture" title="mixed-mode fracture">mixed-mode fracture</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20strain%20energy%20density%20criterion" title=" minimum strain energy density criterion"> minimum strain energy density criterion</a>, <a href="https://publications.waset.org/abstracts/search?q=orthotropic%20materials" title=" orthotropic materials"> orthotropic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20limit%20curve" title=" fracture limit curve"> fracture limit curve</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20II%20critical%20stress%20intensity%20factor" title=" mode II critical stress intensity factor"> mode II critical stress intensity factor</a> </p> <a href="https://publications.waset.org/abstracts/91812/extended-strain-energy-density-criterion-for-fracture-investigation-of-orthotropic-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91812.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">167</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">201</span> Optimal Design of Composite Patch for a Cracked Pipe by Utilizing Genetic Algorithm and Finite Element Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Fakoor">Mahdi Fakoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Navid%20Ghoreishi"> Seyed Mohammad Navid Ghoreishi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Composite patching is a common way for reinforcing the cracked pipes and cylinders. The effects of composite patch reinforcement on fracture parameters of a cracked pipe depend on a variety of parameters such as number of layers, angle, thickness, and material of each layer. Therefore, stacking sequence optimization of composite patch becomes crucial for the applications of cracked pipes. In this study, in order to obtain the optimal stacking sequence for a composite patch that has minimum weight and maximum resistance in propagation of cracks, a coupled Multi-Objective Genetic Algorithm (MOGA) and Finite Element Method (FEM) process is proposed. This optimization process has done for longitudinal and transverse semi-elliptical cracks and optimal stacking sequences and Pareto’s front for each kind of cracks are presented. The proposed algorithm is validated against collected results from the existing literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi%20objective%20optimization" title="multi objective optimization">multi objective optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=pareto%20front" title=" pareto front"> pareto front</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20patch" title=" composite patch"> composite patch</a>, <a href="https://publications.waset.org/abstracts/search?q=cracked%20pipe" title=" cracked pipe"> cracked pipe</a> </p> <a href="https://publications.waset.org/abstracts/67559/optimal-design-of-composite-patch-for-a-cracked-pipe-by-utilizing-genetic-algorithm-and-finite-element-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67559.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">312</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">200</span> Investigation of Mode II Fracture Toughness in Orthotropic Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Fakoor">Mahdi Fakoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabi%20Mehri%20Khansari"> Nabi Mehri Khansari</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmadreza%20Farokhi"> Ahmadreza Farokhi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Evaluation of mode II fracture toughness (KIIC) in composite materials is very hard problem to be solved, since it can be affected by many mechanisms of dissipation. Furthermore, non-linearity in its behavior can offer an extra difficulty to obtain accuracy in the results. Different reported values for KIIC in various references can prove the mentioned assertion. In this research, some solutions proposed based on the form of necessary corrections that should be executed on the common test fixtures. Due to the fact that the common test fixtures are not able to active toughening mechanisms in pure Mode II correctly, we have employed some structural modifications on common fixtures. Particularly, the Iosipescu test is used as start point. The tests are applied on graphite/epoxy; PMMA and Western White Pine Wood. Also, mixed mode I/II fracture limit curves are used to indicate the scattering in test results are really relevant to the creation of Fracture Process Zone (FPZ). In the present paper, shear load consideration applied at the predicted shear zone by considering some significant structural amendments that can active mode II toughening mechanisms. Indeed, the employed empirical method causes significant developing in repeatability and reproducibility as well. Moreover, a 3D Finite Element (FE) is performed for verification of the obtained results. Eventually, it is figured out that, a remarkable precision can be obtained in common test fixture in comparison with the previous one. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FPZ" title="FPZ">FPZ</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20test%20fixture" title=" shear test fixture"> shear test fixture</a>, <a href="https://publications.waset.org/abstracts/search?q=mode%20II%20fracture%20toughness" title=" mode II fracture toughness"> mode II fracture toughness</a>, <a href="https://publications.waset.org/abstracts/search?q=composite%20material" title=" composite material"> composite material</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a> </p> <a href="https://publications.waset.org/abstracts/80199/investigation-of-mode-ii-fracture-toughness-in-orthotropic-materials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80199.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">361</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">199</span> Secrecy Analysis in Downlink Cellular Networks in the Presence of D2D Pairs and Hardware Impairment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Rahimi">Mahdi Rahimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Mojahedian"> Mohammad Mahdi Mojahedian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Aref"> Mohammad Reza Aref</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a cellular communication scenario with a transmitter and an authorized user is considered to analyze its secrecy in the face of eavesdroppers and the interferences propagated unintentionally through the communication network.

In this paper, the use of waterflooding is demonstrated for the petroleum reservoirs of the Kashkari oil field in northern Afghanistan. The technique is based on the Buckley–Leverett frontal-displacement theory, which enables computation of the progress of the waterfront in the reservoir. The relative permeabilities of oil and water, the residual oil saturation, and the irreducible water saturation are obtained from a laboratory experiment. The technique is applied to the laboratory plane-reservoir model to investigate the displacement mechanism and is then compared with the theoretical calculation.

The system is inherently nonlinear and conventional nonlinear controllers are a little complicated, while the proposed hybrid controller has a piecewise linear form, i.e. linear in each sub-region. A state-feedback hybrid controller is designed in this study, and the unmeasurable states are estimated by an observer. The gains of the hybrid controller are obtained by the Linear Quadratic Regulator (LQR) method in each sub-region. To evaluate the performance, the designed controller is implemented on an experimental setup in static mode. The experimental results show that the proposed method can efficiently stabilize the three-pole AMB system. The simplicity of design, domain of attraction, uncomplicated control law, and computational time are advantages of this method over other nonlinear control strategies in AMB systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20magnetic%20bearing" title="active magnetic bearing">active magnetic bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20pole%20AMB" title=" three pole AMB"> three pole AMB</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20control" title=" hybrid control"> hybrid control</a>, <a href="https://publications.waset.org/abstracts/search?q=Lyapunov%20function" title=" Lyapunov function"> Lyapunov function</a> </p> <a href="https://publications.waset.org/abstracts/53804/stabilization-of-a-three-pole-active-magnetic-bearing-by-hybrid-control-method-in-static-mode" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53804.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">341</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">195</span> Investigations of the Crude Oil Distillation Preheat Section in Unit 100 of Abadan Refinery and Its Recommendation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20GoharRokhi">Mahdi GoharRokhi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20H.%20Ruhipour"> Mohammad H.

In order to use these resources, development and functioning optimization of refineries and industrial units is mandatory. Heat exchanger is one of the most important and strategic equipment which its key role in the process of production is clear to everyone. For instance, if the temperature of a processing fluid is not set as needed by heat exchangers, the specifications of desired product can change profoundly. Crude oil enters a network of heat exchangers in atmospheric distillation section before getting into the distillation tower; in this case, well-functioning of heat exchangers can significantly affect the operation of distillation tower. In this paper, different scenarios for pre-heating of oil are studied using oil and gas simulation software, and the results are discussed. As we reviewed various scenarios, adding a heat exchanger to pre-heating network is proposed as the most efficient factor in improving all governing parameters of the tower i.e. temperature, pressure, and reflux rate. This exchanger is embedded in crude oil’s path. Crude oil enters the exchanger after E-101 and exchanges heat with discharging kerosene pump around from E-136. As depicted in the results, it will efficiently assist the improvement of process operation and side expenses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atmospheric%20distillation%20unit" title="atmospheric distillation unit">atmospheric distillation unit</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger" title=" heat exchanger"> heat exchanger</a>, <a href="https://publications.waset.org/abstracts/search?q=preheat" title=" preheat"> preheat</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/50535/investigations-of-the-crude-oil-distillation-preheat-section-in-unit-100-of-abadan-refinery-and-its-recommendation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50535.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">660</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">194</span> Hero’s Journey in the Poetry of Mahdi Akhavsn Sales and T. S. Eliot: A Comparative Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahin%20Pourmorad%20Naseri">Mahin Pourmorad Naseri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Myths have been an inseparable aspect of man’s life in all nations and cultures across the world over time; however, it seems that the form and use of myths in the poetry of the 20th century have gained a new meaning and purpose. Among the poets of the time, T. S. Eliot in English and Mahdi Akhavan Sales in Persian are the two mostly referred to in this regard. In this paper, the pattern of heroic journey as the main theme in the poetry of Akhavan and Eliot will be reviewed, compared, and contrasted. Attempts have been made to find out how the myth of the hero’s journey has been reflected in the century’s well-known poetry and if myth allusions in these poems confirm or reject Campbell’s claim that mythology can be an appropriate psychological cure for man’s loneliness in today’s life. T. S. Eliot (1888-1965), the English poet, essayist, playwright, publisher, and critic, is mostly known for his modernist poetry and the extensive allusions to mythologies and world literary masterpieces. At the same time, Mahdi Akhavan Sales (1929-1990) Iranian poet, one of the pioneers of modern Persian poetry, is also most well-known for his epic poetic style (Khorasani Style) and also his high amount of allusions to myths, especially Zoroastrian mythology, and his myth-making technique. Although their greatly different cultural background may cause the similarities in their poetic style and themes not to attract attention, at first sight, reading the poems closely through the light of the 20th century’s life context and literary movements reveal interesting similarities in the way they understand and apply myth in their poetry. The present paper reviews the theme of the hero’s journey in Akhavan’s Chavooshi and Eliot’s “Journey of the Magi” from the perspective of Campbell’s notion of mono-myth or the pattern of mythic hero’s journey. The poems will be reviewed in search of the steps of the inward journey the heroes make, the goals they pursue, and how successful they are in achieving the goals. The findings of the study reveal that while the difference in the social context of the poets makes the small differences in the stages of the journey, both journeys end in a gloomy atmosphere for the disappointedly isolated hero who is finally left alone in the godless and materialistic world of 20th century. It is also evident that both poets meant to fulfill their responsibility of reviving mythology in writing the poems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=myth" title="myth">myth</a>, <a href="https://publications.waset.org/abstracts/search?q=Akhavan" title=" Akhavan"> Akhavan</a>, <a href="https://publications.waset.org/abstracts/search?q=Eliot" title=" Eliot"> Eliot</a>, <a href="https://publications.waset.org/abstracts/search?q=poetry" title=" poetry"> poetry</a>, <a href="https://publications.waset.org/abstracts/search?q=hero%27s%20journey" title=" hero's journey"> hero's journey</a> </p> <a href="https://publications.waset.org/abstracts/152309/heros-journey-in-the-poetry-of-mahdi-akhavsn-sales-and-t-s-eliot-a-comparative-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152309.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">100</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">193</span> The Frequency of Q Fever Among Hospitalized Patients with Pyrexia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Ali%20Abood%20Nassrullah">Hassan Ali Abood Nassrullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Jabbar%20Fadeel%20Mahdi"> Jabbar Fadeel Mahdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Salih%20Mahdi%20Alkurdi"> Mohammed Salih Mahdi Alkurdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Al%20Mousawi"> Ali Al Mousawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Saad%20Ibrahim%20Al-Ghabban"> Saad Ibrahim Al-Ghabban</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Amir%20H.%20Kadhum"> Abdul Amir H.

Objective: The aim of this study is To estimate the prevalence of cases of Q fever in hospitalized febrile patients in Imam Al Hussain Teaching Medical City in Karbala. Methods: One hundred patients with pyrexia were admitted to the medical ward from 1st August to 31st December 2019. Serological procedures fortified by Enzyme-linked Immunosorbent Assay test. Patients were considered to have acute Q fever when the specific antibodies (IgM and IgG) of phase II of Coxiella burnetii were positive. Results: The mean age of the patients was 35.05±12.93 years; females constituted 60% of them. Eighteen patients (18%) showed positive results for IgM, a lower proportion (13% n=13) had positive IgG levels, and 9% showed equivocal results. Statistical analysis revealed a significant association between positive IgM levels of the female gender and in patients consuming unpasteurized milk. One patient (female aged 60 years) died in the hospital, while all other patients were discharged well. Two female patients were pregnant, and one of them had an abortion. Conclusions: Q fever is more common in febrile patients. The study indicates that this disease should not be overlooked in the differential diagnosis of acute fever. Serological testing should be performed in all patients with acute febrile illness with an unsettling diagnosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibodies" title="antibodies">antibodies</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency" title=" frequency"> frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoglobulin%20IgM" title=" immunoglobulin IgM"> immunoglobulin IgM</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20fever" title=" Q fever"> Q fever</a> </p> <a href="https://publications.waset.org/abstracts/154564/the-frequency-of-q-fever-among-hospitalized-patients-with-pyrexia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154564.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">192</span> A Review of Soil Stabilization Techniques</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amin%20Chegenizadeh">Amin Chegenizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Keramatikerman"> Mahdi Keramatikerman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil stabilization is a crucial issue that helps to remove of risks associated with the soil failure.

In order to limit global warming to 1.5 degrees Celsius, ambitious reductions in the carbon intensity of our buildings are crucial. Passive House presents an opportunity to reduce operational carbon by as much as 90% compared to a traditional building through improving thermal insulation, limiting thermal bridging, increasing airtightness and heat recovery. Up until recently, Passive House design was mainly concerned with meeting the energy demands without considering embodied carbon. As buildings become more energy-efficient, embodied carbon becomes more significant. The main objective of this research is to calculate the embodied carbon impact of a Passive House and compare it with the BC Energy Step Code (ESC). British Columbia is committed to increasing the energy efficiency of buildings through the ESC, which is targeting net-zero energy-ready buildings by 2032. However, there is a knowledge gap in the embodied carbon impacts of more energy-efficient buildings, in particular Part 3 construction. In this case study, life cycle assessments (LCA) are performed on Part 3, a multi-unit residential building in Victoria, BC. The actual building is not constructed to the Passive House standard; however, the building envelope and mechanical systems are designed to comply with the Passive house criteria, as well as Steps 1 and 4 of the BC Energy Step Code (ESC) for comparison. OneClick LCA is used to perform the LCA of the case studies. Several strategies are also proposed to minimize the total carbon emissions of the building. The assumption is that there will not be significant differences in embodied carbon between a Passive House and a Step 4 building due to the building envelope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=embodied%20carbon" title="embodied carbon">embodied carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20modeling" title=" energy modeling"> energy modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20step%20code" title=" energy step code"> energy step code</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20cycle%20assessment" title=" life cycle assessment"> life cycle assessment</a> </p> <a href="https://publications.waset.org/abstracts/130565/comparing-the-embodied-carbon-impacts-of-a-passive-house-with-the-bc-energy-step-code-using-life-cycle-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130565.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">189</span> Effect of Oil Contamination on the Liquefaction Behavior of Sandy Soils</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Abolhasan%20Naeini">Seyed Abolhasan Naeini</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mahdi%20Shojaedin"> Mohammad Mahdi Shojaedin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil leakage from the pipelines and the tanks carrying them, or during oil extraction, could lead to the changes in the characteristics and properties of the soil.

Therefore, NDN-IoT has emerged as a combined architecture which exploits the benefits of NDN for interconnecting of the heterogeneous objects in IoT. In NDN-IoT, caching schemes are a key role to improve the network performance. In this paper, we consider the effectiveness of cache replacement schemes in NDN-IoT scenarios. We investigate the impact of replacement schemes on average delay, average hop count, and average interest retransmission when replacement schemes are Least Frequently Used (LFU), Least Recently Used (LRU), First-In-First-Out (FIFO) and Random. The simulation results demonstrate that LFU and LRU present a stable performance when the cache size changes. Moreover, the network performance improves when the number of consumers increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NDN-IoT" title="NDN-IoT">NDN-IoT</a>, <a href="https://publications.waset.org/abstracts/search?q=cache%20replacement" title=" cache replacement"> cache replacement</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=ndnSIM" title=" ndnSIM"> ndnSIM</a> </p> <a href="https://publications.waset.org/abstracts/84255/on-performance-of-cache-replacement-schemes-in-ndn-iot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84255.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">365</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">185</span> Determination of Optimum Fin Wave Angle and Its Effect on the Performance of an Intercooler</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Hamzehei">Mahdi Hamzehei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyyed%20Amin%20Hakim"> Seyyed Amin Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nahid%20Taherian"> Nahid Taherian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Fins play an important role in increasing the efficiency of compact shell and tube heat exchangers by increasing heat transfer.

This paper proposes a novel routing algorithm that complies with these design requirements. The new routing protocol divides the WSN into several sub-networks and each sub-network is divided into several clusters. This division is designed to reduce the number of radio transmission and hence decreases the power consumption. The network division may be changed dynamically to adapt with the network changes and allows the realization of the design requirements. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wireless%20sensor%20networks" title="wireless sensor networks">wireless sensor networks</a>, <a href="https://publications.waset.org/abstracts/search?q=routing%20protocols" title=" routing protocols"> routing protocols</a>, <a href="https://publications.waset.org/abstracts/search?q=AD%20HOC%20topology" title=" AD HOC topology"> AD HOC topology</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=sub-network" title=" sub-network"> sub-network</a>, <a href="https://publications.waset.org/abstracts/search?q=WSN%20design%20requirements" title=" WSN design requirements"> WSN design requirements</a> </p> <a href="https://publications.waset.org/abstracts/37365/adaptive-routing-protocol-for-dynamic-wireless-sensor-networks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37365.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">537</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">178</span> The Challenges of Hyper-Textual Learning Approach for Religious Education</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elham%20Shirvani%E2%80%93Ghadikolaei">Elham Shirvani–Ghadikolaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mahdi%20Sajjadi"> Seyed Mahdi Sajjadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> State of the art technology has the tremendous impact on our life, in this situation education system have been influenced as well as.

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">176</span> Performance of Environmental Efficiency of Energy Iran and Other Middle East Countries</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bahram%20Fathi">Bahram Fathi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahdi%20Khodaparast%20Mashhadi"> Mahdi Khodaparast Mashhadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Masuod%20Homayounifar"> Masuod Homayounifar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to 1404 forecasting documentation, among the most fundamental ways of Iran’s success in competition with other regional countries are innovations, efficiency enhancements and domestic productivity.
