evaluation of the wind potential for present and future investments in Turkey taking into account the feasibility of sites, installments, operation, and maintenance. This evaluation based on the hourly measured wind speed data for the three years 2008–2010 at 30 m height for Çatalca district. These data were obtained from national meteorology station in Istanbul–Republic of Turkey are analyzed in order to evaluate the feasibility of wind power potential and to assure supreme assortment of wind turbines installing for the area of interest. Furthermore, the data are extrapolated and analyzed at 60 m and 80 m regarding the variability of roughness factor. Weibull bi-parameter probability function is used to approximate monthly and annually wind potential and power density based on three calculation methods namely, the approximated, the graphical and the energy pattern factor methods. The annual mean wind power densities were to be 400.31, 540.08 and 611.02 W/m² for 30, 60, and 80 m heights respectively. Simulation results prove that the analyzed area is an appropriate place for constructing large-scale wind farms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wind%20potential%20in%20Turkey" title="wind potential in Turkey">wind potential in Turkey</a>, <a href="https://publications.waset.org/abstracts/search?q=Weibull%20bi-parameter%20probability%20function" title=" Weibull bi-parameter probability function"> Weibull bi-parameter probability function</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20approximated%20method" title=" the approximated method"> the approximated method</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20graphical%20method" title=" the graphical method"> the graphical method</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20energy%20pattern%20factor%20method" title=" the energy pattern factor method"> the energy pattern factor method</a>, <a href="https://publications.waset.org/abstracts/search?q=capacity%20factor" title=" capacity factor"> capacity factor</a> </p> <a href="https://publications.waset.org/abstracts/86404/feasibility-study-of-wind-energy-potential-in-turkey-case-study-of-catalca-district-in-istanbul" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86404.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">264</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">31083</span> Proposing a New Design Method for Added Viscoelastic Damper’s Application in Steel Moment-Frame</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Javaherzadeh">Saeed Javaherzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Dindar%20Safa"> Babak Dindar Safa </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Structure, given its ductility, can depreciate significant amount of seismic energy in the form of hysteresis behavior; the amount of energy depreciation depends on the structure ductility rate. So in seismic guidelines such as ASCE7-10 code, to reduce the number of design forces and using the seismic energy dissipation capacity of structure, when entering non-linear behavior range of the materials, the response modification factor is used. Various parameters such as ductility modification factor, overstrength factor and reliability factor, are effective in determining the value of this factor. Also, gradually, energy dissipation systems, especially added dampers, have become an inseparable part of the seismic design. In this paper, in addition to reviewing of previous studies, using the response modification factor caused by using more added viscoelastic dampers, a new design method has introduced for steel moment-frame with added dampers installed. To do this, in addition to using bilinear behavior models and quick ways such as using the equivalent lateral force method and capacity spectrum method for the proposed design methodology, the results has been controlled with non-linear time history analysis for a number of structural. The analysis is done by Opensees Software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=added%20viscoelastic%20damper" title="added viscoelastic damper">added viscoelastic damper</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20base%20shear" title=" design base shear"> design base shear</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20modification%20factor" title=" response modification factor"> response modification factor</a>, <a href="https://publications.waset.org/abstracts/search?q=non-linear%20time%20history" title=" non-linear time history"> non-linear time history</a> </p> <a href="https://publications.waset.org/abstracts/31363/proposing-a-new-design-method-for-added-viscoelastic-dampers-application-in-steel-moment-frame" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31363.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">445</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">31082</span> Developing Soil Accumulation Effect Correction Factor for Solar Photovoltaic Module </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kelebaone%20Tsamaase">Kelebaone Tsamaase</a>, <a href="https://publications.waset.org/abstracts/search?q=Rapelang%20Kemoabe"> Rapelang Kemoabe</a>, <a href="https://publications.waset.org/abstracts/search?q=Japhet%20Sakala"> Japhet Sakala</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Rakgati"> Edward Rakgati</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishmael%20Zibani"> Ishmael Zibani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Increasing demand for energy, depletion of non-renewable energy, effects of climate change, the abundance of renewable energy such as solar energy have increased the interest in investing in renewable energies, in particular solar photovoltaic (PV) energy. Solar photovoltaic energy systems as part of clean technology are considered to be environmentally friendly, freely available, offer clean production systems, long term costs benefits as opposed to conventional sources, and are the attractive power source for a wide range of applications in remote areas where there is no easy access to the national grid. To get maximum electrical power, maximum solar power should penetrate the module and be converted accordingly. However, some environmental and other geographical related factors reduce the electrical power. One of them is dust which accumulates on the surface of the module and forming a dust layer and in the process obstructing the solar power from penetrating PV module. This study intends to improve the performance of solar photovoltaic (PV) energy modules by establishing soil accumulation effects correction factor from dust characteristics and properties, and also from dust accumulation and retention pattern on PV module surface. The non-urban dry deposition flux model was adapted to determine monthly and yearly dust accumulation pattern. Consideration was done on prevailing environmental and other geographical conditions. Preliminary results showed that cumulative dust settlement increased during the months of July to October leading to a higher drop in module electrical output power. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dust" title="dust">dust</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20power%20output" title=" electrical power output"> electrical power output</a>, <a href="https://publications.waset.org/abstracts/search?q=PV%20module" title=" PV module"> PV module</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20correction%20factor" title=" soil correction factor"> soil correction factor</a> </p> <a href="https://publications.waset.org/abstracts/124725/developing-soil-accumulation-effect-correction-factor-for-solar-photovoltaic-module" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124725.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">136</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">31081</span> Obtain the Stress Intensity Factor (SIF) in a Medium Containing a Penny-Shaped Crack by the Ritz Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Tavangari">A.

Since many years ago and until now the voltage complex unbalance factor (CVUF) is used only to assess the output energy of the induction motor while this output energy for asymmetry supply voltage does not depend on the value of unbalanced voltage only but also on the machine parameters. The paper illustrates the variation of the two unbalance factors, complex voltage unbalance factor (CVUF) and impedance unbalance factor (IUF), with positive sequence voltage component, reveals that degree and manner of unbalance in supply voltage. From this point of view the paper delineates the current unbalance factor (CUF) to exactly reflect the output energy during unbalanced operation. The paper proceeds to illustrate the importance of using this factor in the multi-machine system to precise prediction of the output energy during the unbalanced operation. The use of the proposed unbalance factor (CUF) avoids the accumulation of the error due to more than one machine in the system which is expected if only the complex voltage unbalance factor (CVUF) is used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=induction%20motor" title="induction motor">induction motor</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20torque" title=" electromagnetic torque"> electromagnetic torque</a>, <a href="https://publications.waset.org/abstracts/search?q=voltage%20unbalance" title=" voltage unbalance"> voltage unbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20conversion" title=" energy conversion"> energy conversion</a> </p> <a href="https://publications.waset.org/abstracts/14861/sensitivity-of-the-estimated-output-energy-of-the-induction-motor-to-both-the-asymmetry-supply-voltage-and-the-machine-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14861.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">565</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">31079</span> Digital Forgery Detection by Signal Noise Inconsistency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo%20Liu">Bo Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Man%20Pun"> Chi-Man Pun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel technique for digital forgery detection by signal noise inconsistency is proposed in this paper.

The triangular and square pattern PCSELs have limited degrees of freedom in tuning the design parameters which hinders the ability to design high quality factor (Q-factor) devices. Nanowire based PCSELs designed using triangular and square patterns have been reported with the lasing thresholds of 130 kW/〖cm〗^2 and 7 kW/〖cm〗^2 respectively. On the other hand the honeycomb pattern gives more degrees of freedom in tuning the design parameters, which can allow one to design high Q-factor devices. A deformed honeycomb pattern device was reported with lasing threshold of 6.25 W/〖cm〗^2 corresponding to a simulated Q-factor of 5.84X〖10〗^5.Despite this achievement, the design principles which can lead to realization of even higher Q-factor honeycomb pattern PCSELs have not yet been investigated. In this work we show that through deforming the honeycomb pattern and tuning the heigh and lattice constants of the nanowires, it is possible to achieve even higher Q-factor devices. Considering three different band edge modes, we investigate how the resonance wavelength changes as the device is deformed, which is useful in designing high Q-factor devices in different wavelength bands. We eventually establish the design and simulation of honeycomb PCSELs operating around the wavelength of 960nm , in the O and the C band with Q-factors up to 7X〖10〗^7. We also investigate the Q-factors of undeformed device, and establish that the mode at the band edge close to 960nm can attain highest Q-factor of all the modes when the device is undeformed and the Q-factor degrades as the device is deformed. This work is a stepping stone towards the fabrication of very high Q-factor, nanowire based honey comb PCSELs, which are expected to have very low lasing threshold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=designing%20nanowire%20PCSEL" title="designing nanowire PCSEL">designing nanowire PCSEL</a>, <a href="https://publications.waset.org/abstracts/search?q=designing%20PCSEL%20on%20silicon%20substrates" title=" designing PCSEL on silicon substrates"> designing PCSEL on silicon substrates</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20threshold%20nanowire%20laser" title=" low threshold nanowire laser"> low threshold nanowire laser</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation%20of%20photonic%20crystal%20lasers" title=" simulation of photonic crystal lasers"> simulation of photonic crystal lasers</a> </p> <a href="https://publications.waset.org/abstracts/193552/design-and-simulation-of-low-threshold-nanowire-photonic-crystal-surface-emitting-lasers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193552.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">22</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">31076</span> Energy Balance Routing to Enhance Network Performance in Wireless Sensor Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Baraneedaran">G.

Due to the limited energy and communication ability of sensor nodes, it seems especially important to design a routing protocol for WSNs so that sensing data can be transmitted to the receiver effectively, an energy-balanced routing method based on forward-aware factor (FAF-EBRM) is proposed in this paper. In FAF-EBRM, the next-hop node is selected according to the awareness of link weight and forward energy density. A spontaneous reconstruction mechanism for Local topology is designed additionally. In this experiment, FAF-EBRM is compared with LEACH and EECU, experimental results show that FAF-EBRM outperforms LEACH and EECU, which balances the energy consumption, prolongs the function lifetime and guarantees high Qos of WSN. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20balance" title="energy balance">energy balance</a>, <a href="https://publications.waset.org/abstracts/search?q=forward-aware%20factor%20%28FAF%29" title=" forward-aware factor (FAF)"> forward-aware factor (FAF)</a>, <a href="https://publications.waset.org/abstracts/search?q=forward%20energy%20density" title=" forward energy density"> forward energy density</a>, <a href="https://publications.waset.org/abstracts/search?q=link%20weight" title=" link weight"> link weight</a>, <a href="https://publications.waset.org/abstracts/search?q=network%20performance" title=" network performance "> network performance </a> </p> <a href="https://publications.waset.org/abstracts/30161/energy-balance-routing-to-enhance-network-performance-in-wireless-sensor-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30161.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">546</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">31075</span> Wt1 and FoxL2 Genes Expression Pattern in Mesonephros-Gonad Complexes of Green Sea Turtle (Chelonia mydas) Embryos Incubated in Feminization and Masculinization Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fitria%20D.%20Ayuningtyas">Fitria D.

GSD (Genotypic Sex Determination) homologous genes such as Wilms’ Tumor (Wt1) and Forkhead Box L2 (FoxL2) play a role in TSD animal sex determination process. Wt1 plays a role in both male pathway, as a transcription factor for Sf1 gene and in female pathway, as a transcription factor for Dax1. FoxL2 plays a role specifically in female sex determination, and known as transcriptional factor for Aromatase gene. Until now, research on the pattern of Wt1 and FoxL2 genes expression in C.mydas has not been conducted yet. The aim of this research is to know the pattern of Wt1 and FoxL2 genes expression in Mesonephros-Gonad (MG) complexes of Chelonia mydas embryos incubated in masculinizing temperature (MT) and feminizing temperature (FT). Eggs of C.mydas incubated in 3 different stage of TSP (Thermosensitive Period) at masculinizing temperature (26±10C, MT) and feminizing temperature (31±10C FT). Mesonefros-gonad complexes were isolated at Pre-TSP stage (FT at days 14th, MT at days 24th), TSP stage (FT at days 24th, MT at days 36th) and differentiated stage (FT at days 40th, MT at days 58th). RNA from mesonephros-gonad (MG) complexes were converted into cDNA by RT-PCR process, and the pattern of Wt1 and FoxL2 genes expression is analyzed by quantitative Real Time PCR (qPCR) method, β-actin gene is used as an internal control. The pattern of Wt1 gene expression in Pre-TSP stage was almost the same between MG complexes incubated at MT or FT, while TSP and differentiation stage, the pattern of Wt1 gene expression in MG complexes incubated at MT or FT was increased. Wt1 gene expression of MG complexes that incubated at FT was higher than at MT. There was a difference pattern between Wt1 gene expression in this research compared to the previous research in protein level. It could be assumed that the difference caused by post-transcriptional regulation mechanisms before mRNA of Wt1 gene translated into protein structure. The pattern of FoxL2 gene expression in Pre-TSP stage was almost the same between MG complexes that incubated at MT and FT, and increased in both TSP and differentiated stage. The FoxL2 gene expression in MG complexes that incubated in FT is higher than MT on TSP and differentiated stage. Based on the results of this research, it can be assumed that Wt1 and FoxL2 gene were expressed in MG complexes that incubated both at MT and FT since Pre-TSP stage. The pattern of Wt1 gene expression was increased in every stage of gonadal development, and so do the pattern of FoxL2 gene expression. Wt1 and FoxL2 gene expressions were higher in MG complexes incubated at FT than MT. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chelonia%20mydas" title="chelonia mydas">chelonia mydas</a>, <a href="https://publications.waset.org/abstracts/search?q=FoxL2" title=" FoxL2"> FoxL2</a>, <a href="https://publications.waset.org/abstracts/search?q=gene%20expression" title=" gene expression"> gene expression</a>, <a href="https://publications.waset.org/abstracts/search?q=TSD" title=" TSD"> TSD</a>, <a href="https://publications.waset.org/abstracts/search?q=Wt1" title=" Wt1"> Wt1</a> </p> <a href="https://publications.waset.org/abstracts/15175/wt1-and-foxl2-genes-expression-pattern-in-mesonephros-gonad-complexes-of-green-sea-turtle-chelonia-mydas-embryos-incubated-in-feminization-and-masculinization-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15175.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">412</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">31074</span> Proposed Pattern for Fitted Men's Suit Jacket Using the Method of Draping on the Mannequin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hazem%20A.%20Abdelfattah">Hazem A.

Macdonald</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: It is well established that dietary composition has effects on metabolism and therefore impacts on health; however other aspects of diet, such as meal pattern, could also be important in both obesity management and promoting health. The present study investigated the effect of irregular meal frequency on anthropometric measurements and energy expenditure (EE) in healthy women. Design: 11 healthy weight women (18–40 years) were studied in a randomized crossover trial with two phases of 2 weeks each. In Phase 1, participants consumed either a regular meal pattern (6 meals/day) or an irregular meal pattern (varying from 3 to 9 meals/day). In Phase 2, participants followed the alternative meal pattern to that followed in Phase 1, after a 2-weeks washout period. In the two phases, identical foods were provided to a participant in amounts designed to keep body weight constant. Participants came to the laboratory after an overnight fast at the start and end of each phase. EE was measured in fasting state by indirect calorimetry. Postprandial EE was measured during the 3 h period after consumption of a milkshake, test drink. Results: There were no significant changes in body weight and anthropometric measurements after both meal pattern interventions. There was also no significant difference in mean daily energy intake between the regular and irregular meal pattern (2043 ±31 and 2099 ±33 respectively). EE in the fasting state showed no significant differences cross the experiment visits. There was a significant difference in Postprandial EE (measured for 3 h) by visit (P=0.04). Postprandial EE after the regular meal pattern was significantly higher than at baseline (P=0.002) or than after the irregular meal pattern (P= 0.04). Conclusion: Eating regularly for 14-day period significantly increases Postprandial EE which may contribute to weight loss and obesity management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20expenditure" title="energy expenditure">energy expenditure</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20intake" title=" energy intake"> energy intake</a>, <a href="https://publications.waset.org/abstracts/search?q=meal%20pattern" title=" meal pattern"> meal pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss" title=" weight loss"> weight loss</a> </p> <a href="https://publications.waset.org/abstracts/27426/irregular-meal-pattern-what-is-the-impact-on-weight" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27426.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">417</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">31072</span> Surface Flattening Assisted with 3D Mannequin Based on Minimum Energy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shih-Wen%20Hsiao">Shih-Wen Hsiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong-Qi%20Chen"> Rong-Qi Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Chien-Yu%20Lin"> Chien-Yu Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The topic of surface flattening plays a vital role in the field of computer aided design and manufacture. Surface flattening enables the production of 2D patterns and it can be used in design and manufacturing for developing a 3D surface to a 2D platform, especially in fashion design. This study describes surface flattening based on minimum energy methods according to the property of different fabrics. Firstly, through the geometric feature of a 3D surface, the less transformed area can be flattened on a 2D platform by geodesic. Then, strain energy that has accumulated in mesh can be stably released by an approximate implicit method and revised error function. In some cases, cutting mesh to further release the energy is a common way to fix the situation and enhance the accuracy of the surface flattening, and this makes the obtained 2D pattern naturally generate significant cracks. When this methodology is applied to a 3D mannequin constructed with feature lines, it enhances the level of computer-aided fashion design. Besides, when different fabrics are applied to fashion design, it is necessary to revise the shape of a 2D pattern according to the properties of the fabric. With this model, the outline of 2D patterns can be revised by distributing the strain energy with different results according to different fabric properties. Finally, this research uses some common design cases to illustrate and verify the feasibility of this methodology. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20flattening" title="surface flattening">surface flattening</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20energy" title=" strain energy"> strain energy</a>, <a href="https://publications.waset.org/abstracts/search?q=minimum%20energy" title=" minimum energy"> minimum energy</a>, <a href="https://publications.waset.org/abstracts/search?q=approximate%20implicit%20method" title=" approximate implicit method"> approximate implicit method</a>, <a href="https://publications.waset.org/abstracts/search?q=fashion%20design" title=" fashion design"> fashion design</a> </p> <a href="https://publications.waset.org/abstracts/7579/surface-flattening-assisted-with-3d-mannequin-based-on-minimum-energy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7579.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">343</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">31071</span> Energy Consumption Modeling for Strawberry Greenhouse Crop by Adaptive Nero Fuzzy Inference System Technique: A Case Study in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azar%20Khodabakhshi">Azar Khodabakhshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Bolandnazar"> Elham Bolandnazar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Agriculture as the most important food manufacturing sector is not only the energy consumer, but also is known as energy supplier. Using energy is considered as a helpful parameter for analyzing and evaluating the agricultural sustainability. In this study, the pattern of energy consumption of strawberry greenhouses of Jiroft in Kerman province of Iran was surveyed. The total input energy required in the strawberries production was calculated as 113314.71 MJ /ha. Electricity with 38.34% contribution of the total energy was considered as the most energy consumer in strawberry production. In this study, Neuro Fuzzy networks was used for function modeling in the production of strawberries. Results showed that the best model for predicting the strawberries function had a correlation coefficient, root mean square error (RMSE) and mean absolute percentage error (MAPE) equal to 0.9849, 0.0154 kg/ha and 0.11% respectively. Regards to these results, it can be said that Neuro Fuzzy method can be well predicted and modeled the strawberry crop function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20yield" title="crop yield">crop yield</a>, <a href="https://publications.waset.org/abstracts/search?q=energy" title=" energy"> energy</a>, <a href="https://publications.waset.org/abstracts/search?q=neuro-fuzzy%20method" title=" neuro-fuzzy method"> neuro-fuzzy method</a>, <a href="https://publications.waset.org/abstracts/search?q=strawberry" title=" strawberry"> strawberry</a> </p> <a href="https://publications.waset.org/abstracts/70034/energy-consumption-modeling-for-strawberry-greenhouse-crop-by-adaptive-nero-fuzzy-inference-system-technique-a-case-study-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70034.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">390</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">31070</span> Tensile Force Estimation for Real-Size Pre-Stressed Concrete Girder using Embedded Elasto-Magnetic Sensor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junkyeong%20Kim">Junkyeong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jooyoung%20Park"> Jooyoung Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Aoqi%20Zhang"> Aoqi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Seunghee%20Park"> Seunghee Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The tensile force of Pre-Stressed Concrete (PSC) girder is the most important factor for evaluating the performance of PSC girder bridges. To measure the tensile force of PSC girder, several NDT methods were studied. However, conventional NDT method cannot be applied to the real-size PSC girder because the PS tendons could not be approached. To measure the tensile force of real-size PSC girder, this study proposed embedded EM sensor based tensile force estimation method. The embedded EM sensor could be installed inside of PSC girder as a sheath joint before the concrete casting. After curing process, the PS tendons were installed, and the tensile force was induced step by step using hydraulic jacking machine. The B-H loop was measured using embedded EM sensor at each tensile force steps and to compare with actual tensile force, the load cell was installed at each end of girder. The magnetization energy loss, that is the closed area of B-H loop, was decreased according to the increase of tensile force with regular pattern. Thus, the tensile force could be estimated by the tracking the change of magnetization energy loss of PS tendons. Through the experimental result, the proposed method can be used to estimate the tensile force of the in-situ real-size PSC girder bridge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tensile%20force%20estimation" title="tensile force estimation">tensile force estimation</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20EM%20sensor" title=" embedded EM sensor"> embedded EM sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetization%20energy%20loss" title=" magnetization energy loss"> magnetization energy loss</a>, <a href="https://publications.waset.org/abstracts/search?q=PSC%20girder" title=" PSC girder"> PSC girder</a> </p> <a href="https://publications.waset.org/abstracts/57237/tensile-force-estimation-for-real-size-pre-stressed-concrete-girder-using-embedded-elasto-magnetic-sensor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57237.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">348</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">31069</span> Disaggregating and Forecasting the Total Energy Consumption of a Building: A Case Study of a High Cooling Demand Facility</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juliana%20Barcelos%20Cordeiro">Juliana Barcelos Cordeiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Khashayar%20Mahani"> Khashayar Mahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Farbod%20Farzan"> Farbod Farzan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohsen%20A.%20Jafari"> Mohsen A.

Companies have been investing in technologies to come up with software and/or hardware solutions that can provide this type of information to the consumer. On the other hand, not all people can afford to have these technologies. Therefore, in this paper, we present a methodology for breaking down the aggregate consumption and identifying the highdemanding end-uses profiles. These energy profiles will be used to build the forecast model for optimal control purpose. A facility with high cooling load is used as an illustrative case study to demonstrate the results of proposed methodology. We apply a high level energy disaggregation through a pattern recognition approach in order to extract the consumption profile of its rooftop packaged units (RTUs) and present a forecast model for the energy consumption.   <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20consumption%20forecasting" title="energy consumption forecasting">energy consumption forecasting</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=load%20disaggregation" title=" load disaggregation"> load disaggregation</a>, <a href="https://publications.waset.org/abstracts/search?q=pattern%20recognition%20approach" title=" pattern recognition approach"> pattern recognition approach</a> </p> <a href="https://publications.waset.org/abstracts/44047/disaggregating-and-forecasting-the-total-energy-consumption-of-a-building-a-case-study-of-a-high-cooling-demand-facility" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44047.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">283</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">31068</span> Analysis of Three-Dimensional Cracks in an Isotropic Medium by the Semi-Analytical Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdoulnabi%20Tavangari">Abdoulnabi Tavangari</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasim%20Salehzadeh"> Nasim Salehzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We presume a cylindrical medium that is under a uniform loading and there is a penny shaped crack located in the center of cylinder. In the crack growth analysis, the Stress Intensity Factor (SIF) is a fundamental prerequisite. In the present study, according to the RITZ method and by considering a cylindrical coordinate system as the main coordinate and a local polar coordinate, the mode-I SIF of threedimensional penny-shaped crack is obtained. In this method the unknown coefficients will be obtained with minimizing the potential energy that is including the strain energy and the external force work. By using the hook's law, stress fields will be obtained and then by using the Irvine equations, the amount of SIF will be obtained near the edge of the crack. This question has been solved for extreme medium in the Tada handbook and the result of the present research has been compared with that. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=three-dimensional%20cracks" title="three-dimensional cracks">three-dimensional cracks</a>, <a href="https://publications.waset.org/abstracts/search?q=penny-shaped%20crack" title=" penny-shaped crack"> penny-shaped crack</a>, <a href="https://publications.waset.org/abstracts/search?q=stress%20intensity%20factor" title=" stress intensity factor"> stress intensity factor</a>, <a href="https://publications.waset.org/abstracts/search?q=fracture%20mechanics" title=" fracture mechanics"> fracture mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=Ritz%20method" title=" Ritz method"> Ritz method</a> </p> <a href="https://publications.waset.org/abstracts/29894/analysis-of-three-dimensional-cracks-in-an-isotropic-medium-by-the-semi-analytical-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29894.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">400</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">31067</span> Growth Pattern and Condition Factor of Oreochromis niloticus and Sarotherodon galilaeus in Epe Lagoon, Lagos State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Bolaji%20Alarape">Ahmed Bolaji Alarape</a>, <a href="https://publications.waset.org/abstracts/search?q=Oluwatobi%20Damilola%20Aba"> Oluwatobi Damilola Aba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The growth pattern of Oreochromis niloticus and Sarotherodon galilaeus in Epe Lagoon Lagos State was investigated. One hundred (100) samples of each species were collected from fishermen at the landing site. They were transported to the Fisheries Laboratory of National Institute of Oceanography for identification, sexing morphometric measurement. The results showed that 58.0% and 56.0 % of the O.niloticus and S.galilaeus were female respectively while 42.0% and 44.0% were male respectively. The length-weight relationship of O.niloticus showed a strong regression coefficient (r = 0.944) (p<0.05) for the combined sex, (r =0.901) (p<0.05) for female and (r=0.985) (p<.05) for male with b-value of 2.5, 3.1 and 2.8 respectively. The S.galilaeus also showed a regression coefficient of r=0.970; p<0.05 for the combined sex, r=0.953; p<0.05 for the female and r= 0.979; p<0.05 for the male with b-value of 3.4, 3.1 and 3.6 respectively. O.niloticus showed an isometric growth pattern both in male and female. The condition factor in O.niloticus are 1.93 and 1.95 for male and female respectively while that of S.galilaeus is 1.95 for both sexes. Positive allometric was observed in both species except the male O.niloticus that showed negative allometric growth pattern. From the results of this study, the growth pattern of the two species indicated a good healthy environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Epe%20Lagoon" title="Epe Lagoon">Epe Lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=length-weight%20relationship" title=" length-weight relationship"> length-weight relationship</a>, <a href="https://publications.waset.org/abstracts/search?q=Oreochromis%20niloticus" title=" Oreochromis niloticus"> Oreochromis niloticus</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarotherodon%20galilaeus" title=" Sarotherodon galilaeus"> Sarotherodon galilaeus</a> </p> <a href="https://publications.waset.org/abstracts/94857/growth-pattern-and-condition-factor-of-oreochromis-niloticus-and-sarotherodon-galilaeus-in-epe-lagoon-lagos-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94857.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">31066</span> De Broglie Wavelength Defined by the Rest Energy E0 and Its Velocity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Orozovi%C4%87">K.

In this way, we can show the connection between the quantum of radiation energy of the body and the rest of energy E₀ and thus combine what has been incompatible so far, namely relativistic and quantum physics.

Over recent decades, much work has been done to develop simulation tools for vehicle NVH. At the medium high-frequency range, the statistical energy analysis method (SEA) shows significant effectiveness in predicting noise and vibration responses of mechanical systems. In this paper, the evaluation of the sound pressure level (SPL) inside an automobile cabin has been performed numerically using the statistical energy analysis (SEA) method. A test car cabin was performed using a monopole source as a sound source. The decay rate method was employed to obtain the damping loss factor (DLF) of each subsystem of the developed SEA model. These parameters were then used to predict the sound pressure level in the interior cabin. The results show satisfactory agreement with the directly measured SPL. The developed SEA vehicle model can be used in early design phases and allows the engineer to identify sources contributing to the total noise and transmission paths. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SEA" title="SEA">SEA</a>, <a href="https://publications.waset.org/abstracts/search?q=SPL" title=" SPL"> SPL</a>, <a href="https://publications.waset.org/abstracts/search?q=DLF" title=" DLF"> DLF</a>, <a href="https://publications.waset.org/abstracts/search?q=NVH" title=" NVH"> NVH</a> </p> <a href="https://publications.waset.org/abstracts/166408/a-statistical-energy-analysis-model-of-an-automobile-for-the-prediction-of-the-internal-sound-pressure-level" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166408.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">95</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">31064</span> Development of a Suitable Model for Energy Storage in Residential Buildings in Ahvaz Using Energy Plus Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farideh%20Azimi">Farideh Azimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sam%20Vahedi%20Tafreshi"> Sam Vahedi Tafreshi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research tries to study the residential buildings in Ahvaz, the common materials used, and the impact of passive methods of energy storage (as one of the most effective ways to reduce energy consumption in residential complexes) in order to achieve patterns for construction of residential buildings in Ahvaz conditions to reduce energy consumption. In this research, after studying Ahvaz conditions, the components of an existing building were simulated in Energy Plus software, and the climatic data of Ahvaz station was introduced to software. Then to achieve the most optimal conditions of energy consumption in Ahvaz conditions, each of the residential building elements was optimized. The results of simulation showed that using inactive materials and design including double glass, outside wall insulation, inverted roof, etc. in the buildings can reduce energy consumption in the hot and dry climate of Ahvaz. Among the parameters investigated, the inverted roof was the most effective energy saving pattern. According to the results of simulation of the entire building with the most optimal parameters, energy consumption can be saved by a mean of 12.51% in buildings of Ahvaz, and the obtained pattern can also be used in similar climates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=residential%20buildings" title="residential buildings">residential buildings</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20comfort" title=" thermal comfort"> thermal comfort</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=Energy%20Plus%20software" title=" Energy Plus software"> Energy Plus software</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahvaz" title=" Ahvaz"> Ahvaz</a> </p> <a href="https://publications.waset.org/abstracts/72133/development-of-a-suitable-model-for-energy-storage-in-residential-buildings-in-ahvaz-using-energy-plus-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72133.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">366</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">31063</span> [Keynote Speech]: Competitive Evaluation of Power Plants in Energy Policy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beril%20Tu%C4%9Frul">Beril Tuğrul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical energy is the most important form of energy and electrical power plants have highest impact factor in energy policy.

In this study, two-segment crash box design with holes is investigated under oblique load. The deformation behavior and crash energy absorption are observed. The analysis was performed using finite element method. The crash test components were impactor, crash box, and fixed rigid base. Impactor and the fixed base material are modelled as a rigid, and crash box material as bilinear isotropic hardening. The models consist of 2 and 4 holes laid within ¼, ½ and ¾ from first segment length. 100 mm aluminum crash box and frontal crash velocity of 16 km/jam were selected. Based on simulation results, it can be concluded that 2 holes located at ¾ has the largest crash energy absorption. This behavior associated with deformation pattern, which produces higher number of folding than other models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crash%20Box" title="crash Box">crash Box</a>, <a href="https://publications.waset.org/abstracts/search?q=two-segments" title=" two-segments"> two-segments</a>, <a href="https://publications.waset.org/abstracts/search?q=holes%20configuration" title=" holes configuration"> holes configuration</a>, <a href="https://publications.waset.org/abstracts/search?q=oblique%20load" title=" oblique load"> oblique load</a>, <a href="https://publications.waset.org/abstracts/search?q=deformation%20pattern" title=" deformation pattern"> deformation pattern</a> </p> <a href="https://publications.waset.org/abstracts/40085/performances-of-two-segment-crash-box-with-holes-under-oblique-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40085.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">364</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">31061</span> An Optimized Method for Calculating the Linear and Nonlinear Response of SDOF System Subjected to an Arbitrary Base Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Kabir">Hossein Kabir</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Sadeghi"> Mojtaba Sadeghi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Finding the linear and nonlinear responses of a typical single-degree-of-freedom system (SDOF) is always being regarded as a time-consuming process.

The effect of stitching reinforcement through thickness on using glass flux yarn on energy absorption of fiber-reinforced polymer (FRP) was investigated under high speed loading conditions at axial loading. Keeping the mass of the structure at 125 grams and applying different pattern of stitching at various locations in theory enables better energy absorption, and also enables the control over the behaviour of force-crush distance curve. The study consists of simple non-stitch absorber comparison with single and multi-location stitching behaviour and its effect on energy absorption capabilities. The locations of reinforcements are 10 mm, 20 mm, 30 mm, 10-20 mm, 10-30 mm, 20-30 mm, 10-20-30 mm and 10-15-20-25-30-35 mm from the top of the specimen. The effect of through the thickness reinforcements has shown increase in energy absorption capabilities and crushing load. The significance of this is that as the stitching locations are closer, the crushing load increases and consequently energy absorption capabilities are also increased. The implementation of this idea would improve the mean force by applying stitching and controlling the behaviour of force-crush distance curve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=through-thickness%20stitching" title="through-thickness stitching">through-thickness stitching</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20enforcement%E2%80%8B" title=" 3D enforcement"> 3D enforcement</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=tubular%20composite%20structures" title=" tubular composite structures"> tubular composite structures</a> </p> <a href="https://publications.waset.org/abstracts/55255/effect-of-stitching-pattern-on-composite-tubular-structures-subjected-to-quasi-static-crushing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55255.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">269</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">31059</span> Study on Energy Absorption Characteristic of Cab Frame with FEM</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shigeyuki%20Haruyama">Shigeyuki Haruyama</a>, <a href="https://publications.waset.org/abstracts/search?q=Oke%20Oktavianty"> Oke Oktavianty</a>, <a href="https://publications.waset.org/abstracts/search?q=Zefry%20Darmawan"> Zefry Darmawan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tadayuki%20Kyoutani"> Tadayuki Kyoutani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ken%20Kaminishi"> Ken Kaminishi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cab’s frame strength is considered as an important factor in excavator’s operator safety, especially during roll-over.

The results is shown which the element-free method was of good accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stress%20intensity%20factor" title="stress intensity factor">stress intensity factor</a>, <a href="https://publications.waset.org/abstracts/search?q=crack" title=" crack"> crack</a>, <a href="https://publications.waset.org/abstracts/search?q=torsional%20loading" title=" torsional loading"> torsional loading</a>, <a href="https://publications.waset.org/abstracts/search?q=meshless%20method" title=" meshless method "> meshless method </a> </p> <a href="https://publications.waset.org/abstracts/18554/calculating-stress-intensity-factor-of-cracked-axis-by-using-a-meshless-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/18554.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">572</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">31056</span> Sun Protection Factor (SPF) Determination of Sericin Cream and Niosomal Gel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farzad%20Doostishoar">Farzad Doostishoar</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Pardakhty"> Abbas Pardakhty</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Hassanzadeh"> Abdolreza Hassanzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sudeh%20salarpour"> Sudeh salarpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sharif"> Elham Sharif</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Sericin is a protein extracted from silk and has antioxidant, antimicrobial, antineoplastic, wound healing and moisturizing properties. Different cosmetic formulation of sericin is available in different countries such as Japan and the other south-eastern Asian countries. We formulated and evaluated the sunscreen properties of topical formulations of sericin by an in vitro method. Method: Niosomes composed of sorbitan palmitate (Span 40), polysorbate 40 (Tween 40) and cholesterol (300 µmol, 3.5:3.5:3 molar ratio) were prepared by film hydration technique. Sericin was dissolved in normal saline and the lipid hydration was carried out at 60°C and the niosomes were incorporated in a Carbomer gel base. A W/O cream was also prepared and the release of sericin was evaluated by using Franz diffusion cell. Particle size analysis, sericin encapsulation efficiency measurement, morphological studies and stability evaluation were done in niosomal formulations. SPF was calculated by using Transpore tape in vitro method for both formulations. Results: Niosomes had high stability during 6 months storage at 4-8°C. The mean volume diameter of niosomes was less than 7 µm which is ideal for sustained release of drugs in topical formulations. The SPF of niosomal gel was 25 and higher than sericin cream with a diffusion based release pattern of active material. Conclusion: Sericin can be successfully entrapped in niosomes with sustained release pattern and relatively high SPF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sericin" title="sericin">sericin</a>, <a href="https://publications.waset.org/abstracts/search?q=niosomes" title=" niosomes"> niosomes</a>, <a href="https://publications.waset.org/abstracts/search?q=sun%20protection%20factor" title=" sun protection factor"> sun protection factor</a>, <a href="https://publications.waset.org/abstracts/search?q=cream" title=" cream"> cream</a>, <a href="https://publications.waset.org/abstracts/search?q=gel" title=" gel"> gel</a> </p> <a href="https://publications.waset.org/abstracts/25326/sun-protection-factor-spf-determination-of-sericin-cream-and-niosomal-gel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25326.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">509</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">31055</span> Pattern Synthesis of Nonuniform Linear Arrays Including Mutual Coupling Effects Based on Gaussian Process Regression and Genetic Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming%20Su">Ming Su</a>, <a href="https://publications.waset.org/abstracts/search?q=Ziqiang%20Mu"> Ziqiang Mu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a synthesis method for nonuniform linear antenna arrays that combine Gaussian process regression (GPR) and genetic algorithm (GA). In this method, the GPR model can be used to calculate the array radiation pattern in the presence of mutual coupling effects, and then the GA is used to optimize the excitations and locations of the elements so as to generate the desired radiation pattern. In this paper, taking a 9-element nonuniform linear array as an example and the desired radiation pattern corresponding to a Chebyshev distribution as the optimization objective, optimize the excitations and locations of the elements. Finally, the optimization results are verified by electromagnetic simulation software CST, which shows that the method is effective. <p class="card-text"><strong>Keywords:</strong> <a
