infrastructure and smart meters have facilitated the utilization of demand-side resources which can enhance stability and economic efficiency of power systems. Direct load control programs can play an important role in the utilization of demand-side resources in the residential sector. However, investments required for installing control equipment can be a limiting factor in the development of such demand response programs. Thus, selection of consumers with higher potentials is crucial to the success of a direct load control program. Heating, ventilation, and air conditioning (HVAC) systems, which due to the heat capacity of buildings feature relatively high flexibility, make up a major part of household consumption. Considering that the consumption of HVAC systems depends highly on the ambient temperature and bearing in mind the high investments required for control systems enabling direct load control demand response programs, in this paper, a recent solution is presented to uncover consumers with high air conditioner demand among large number of consumers and to measure the demand response potential of such consumers. This can pave the way for estimating the investments needed for the implementation of direct load control programs for residential HVAC systems and for estimating the demand response potentials in a distribution system. In doing so, we first cluster consumers into several groups based on the correlation coefficients between hourly consumption data and hourly temperature data using K-means algorithm. Then, by applying a recent algorithm to the hourly consumption and temperature data, consumers with high air conditioner consumption are identified. Finally, demand response potential of such consumers is estimated based on the equivalent desired temperature setpoint changes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=communication%20infrastructure" title="communication infrastructure">communication infrastructure</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20meters" title=" smart meters"> smart meters</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20systems" title=" power systems"> power systems</a>, <a href="https://publications.waset.org/abstracts/search?q=HVAC%20system" title=" HVAC system"> HVAC system</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20HVAC%20systems" title=" residential HVAC systems"> residential HVAC systems</a> </p> <a href="https://publications.waset.org/abstracts/170684/two-level-separation-of-high-air-conditioner-consumers-and-demand-response-potential-estimation-based-on-set-point-change" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170684.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">66</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">257</span> Flow Duration Curve Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

In the present study, the mortalities of Lucilia Cuprina as the key pest of meat were studied after being exposed to HICIDE VD-9 (a ready-to-use disinfectant/insecticide containing cypermethrin, polyhexanide and quaternary ammonium compounds produced by Dana pharmed lotus Co., Iran) within 15 minutes. The experimental results showed that moralities percentage of egg, larvae and adults of Lucilia Cuprina were 48%, 81% and 70%, respectively. Based on the obtained results, it can be predicted that in addition to controlling the insect pests of blow flies, HICIDE VD-9, as a cost-effective and environmentally friendly disinfectant/insecticide, can be effective against other insects, e.g., biting flies, fleas, midges, mosquitoes and ticks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cypermethrin" title="cypermethrin">cypermethrin</a>, <a href="https://publications.waset.org/abstracts/search?q=HICIDE%20VD-9" title=" HICIDE VD-9"> HICIDE VD-9</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucilia%20cuprina" title=" Lucilia cuprina"> Lucilia cuprina</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=toxicity" title=" toxicity"> toxicity</a> </p> <a href="https://publications.waset.org/abstracts/176093/the-toxicity-effects-of-hicide-vd-9-on-the-mortality-of-lucilia-cuprina-under-laboratory-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176093.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">110</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">253</span> Hydrological Method to Evaluate Environmental Flow: Case Study of Gharasou River, Ardabil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Fuladipanah">Mehdi Fuladipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Jorabloo"> Mehdi Jorabloo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water flow management is one of the most important parts of river engineering.

Multi-terminal DC wind farm topologies are attracting increasing research attempt. With AC/DC converters on the generator side, this topology can be developed into a multi-terminal DC network for wind power collection, which is especially suitable for large-scale offshore wind farms. For wind farms, the topology uses high-voltage direct-current transmission based on voltage-source converters (VSC-HVDC). Therefore, they do not suffer from over currents due to DC cable faults and there is no over current to react to. In this study, the multi-terminal DC wind farm topology is introduced. Then, possible internal DC faults are analyzed according to type and characteristic. Fault over current expressions are given in detail. Under this characteristic analysis, fault detection and detailed protection methods are proposed. Theoretical analysis and PSCAD/EMTDC simulations are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%20short%20circuits" title="DC short circuits">DC short circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-terminal%20DC%20wind%20farm%20topologies" title=" multi-terminal DC wind farm topologies"> multi-terminal DC wind farm topologies</a>, <a href="https://publications.waset.org/abstracts/search?q=HVDC%20transmission%20based%20on%20VSC" title=" HVDC transmission based on VSC"> HVDC transmission based on VSC</a>, <a href="https://publications.waset.org/abstracts/search?q=fault%20analysis" title=" fault analysis"> fault analysis</a> </p> <a href="https://publications.waset.org/abstracts/10282/internal-dc-short-circuit-fault-analysis-and-protection-for-vsi-of-wind-power-generation-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10282.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">421</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">251</span> Numerical Study of Partial Penetration of PVDs In Soft Clay Soils Treatment Along With Surcharge Preloading (Bangkok Airport Case Study)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mehdi%20Pardsouie">Mohammad Mehdi Pardsouie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mokhberi"> Mehdi Mokhberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Ali%20Zomorodian"> Seyed Mohammad Ali Zomorodian</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Alireza%20Nasehi"> Seyed Alireza Nasehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the challenging parts of every project, including prefabricated vertical drains (PVDs), is the determination of the depth of installation and its configuration. In this paper, Geostudio 2018 was used for modeling and verification of the full-scale test embankments (TS1, TS2, and TS3), which were constructed to study the effectiveness of PVDs for accelerating the consolidation and dissipation of the excess pore-pressures resulting from fill placement at Bangkok airport. Different depths and scenarios were modeled and the results were compared and analyzed. Since the ultimate goal is attaining pre-determined settlement, the settlement curve under soil embankment was used for the investigation of the results. It was shown that nearly in all cases, the same results and efficiency might be obtained by partial depth installation of PVDs instead of complete full constant length installation. However, it should be mentioned that because of distinct soil characteristics of clay soils and layers properties of any project, further investigation of full-scale test embankments and modeling is needed prior to finalizing the ultimate design by competent geotechnical consultants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20penetration" title="partial penetration">partial penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge%20preloading" title=" surcharge preloading"> surcharge preloading</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20pore%20water%20pressure" title=" excess pore water pressure"> excess pore water pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20test%20embankments" title=" Bangkok test embankments"> Bangkok test embankments</a> </p> <a href="https://publications.waset.org/abstracts/143189/numerical-study-of-partial-penetration-of-pvds-in-soft-clay-soils-treatment-along-with-surcharge-preloading-bangkok-airport-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143189.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">207</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">250</span> RANS Simulation of the LNG Ship Squat in Shallow Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nakisa">Mehdi Nakisa</a>, <a href="https://publications.waset.org/abstracts/search?q=Adi%20Maimun"> Adi Maimun</a>, <a href="https://publications.waset.org/abstracts/search?q=Yasser%20M.%20Ahmed"> Yasser M.

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

Our purpose is to enhance the ability of solving the mentioned nonlinear differential equation with a simple and innovative approach.

This system is a useful tool for Digital Signal Processing (DSP) since it can support parallel, carry-free, high-speed and low power arithmetic. One of the drawbacks of Residue Number System is the fractional numbers, that is, the corresponding circuit is very hard to realize in conventional CMOS technology. In this paper, we propose a method in which the numbers of transistors are significantly reduced. The related delay is extremely diminished, in the first glance we use this method to solve concerning problem of one decimal functional number some how this proposition can be extended to generalize the idea.

Among other modern literary works, Beckett's path-breakingly innovative literature presented the parodies of pointlessness of human actions and thoughts in the world. This new dramatic style catapulted Beckett to the centre stage of modern drama, though it should be mentioned that he may not have been influenced in this without the prevailing climate of ideas. The prevailing literary attitude of Modernism indicates that the modern world is irrational and incoherent. The present study explores Samuel Beckett's literary approach to modern drama and shows how the author could create the characters stuck in a lifelong suspicious about the Self. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=modern%20drama" title="modern drama">modern drama</a>, <a href="https://publications.waset.org/abstracts/search?q=absurdity" title=" absurdity"> absurdity</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20theatre%20of%20the%20absurd" title=" the theatre of the absurd"> the theatre of the absurd</a>, <a href="https://publications.waset.org/abstracts/search?q=existentialism" title=" existentialism"> existentialism</a>, <a href="https://publications.waset.org/abstracts/search?q=self%20searching" title=" self searching "> self searching </a> </p> <a href="https://publications.waset.org/abstracts/12117/modern-literary-authors-and-samuel-becketts-trace-of-lost-self-in-modernity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12117.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">529</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">233</span> Removal of Samarium in Environmental Water Samples by Modified Yeast Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Homayon%20Ahmad%20Panahi">Homayon Ahmad Panahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mehdi%20Seyed%20Nejad"> Seyed Mehdi Seyed Nejad</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Moniri"> Elham Moniri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A novel bio-adsorbent is fabricated by attaching a cibacron blue to yeast cells.

The aim is to protect these structures from serious damages while subjected to impact loads, or to minimize human injuries while collision is occurred in transportation systems. These energy-absorbing devices can dissipate kinetic energy in a wide variety of ways like friction, facture, plastic bending, crushing, cyclic plastic deformation and metal cutting. On the other hand, various structures may be used as collapsible energy absorbers. Metallic cylindrical tubes have attracted much more attention due to their high stiffness and strength combined with the low weight and ease of manufacturing process. As a matter of fact, favorable crash worthiness characteristics for energy dissipation purposes can be achieved from axial collapse of tubes while they crush progressively in symmetric modes. However, experimental and theoretical results have shown that depending on various parameters such as tube geometry, material properties of tube, boundary and loading conditions, circular tubes buckle in different modes of deformation, namely, diamond and Euler collapsing modes. It is shown that when the tube length is greater than the critical length, the tube deforms in overall Euler buckling mode, which is an inefficient mode of energy absorption and needs to be avoided in crash worthiness applications. This study develops a new method with the aim of improving energy absorption characteristics of long steel circular tubes. Inserting a helical spring into the tubes is proved experimentally to be an efficient solution. In fact when a long tube is subjected to axial compression load, the spring prevents of undesirable Euler or diamond collapsing modes. This is because the spring reinforces the internal wall of tubes and it causes symmetric deformation in tubes. In this research three specimens were prepared and three tests were performed. The dimensions of tubes were selected so that in axial compression load buckling is occurred. In the second and third tests a spring was inserted into tubes and they were subjected to axial compression load in quasi-static and impact loading, respectively. The results showed that in the second and third tests buckling were not happened and the tubes deformed in symmetric modes which are desirable in energy absorption. <p
