The geometry of the conduit is of a four-parallel-channels system including one inflow channel and three outflow channels. The liquid-metal flows in the inflow channel, then turns 1800 in the transition segment, finally flows into three different outflow channels simultaneously. This kind of channel system can induce counter flow and co-flow, which is rarely investigated before. The axial velocity in the side layer near the first partitioning wall, which is located between the inflow channel and the first outflow channel, is the highest. ‘M-shaped’ velocity profiles are obtained in the side layers of the inflow and outflow channels. The interdependency of the current, fluid velocity, pressure, electric potential is examined in order to describe the electromagnetic characteristics of the liquid-metal flows. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid-metal" title="liquid-metal">liquid-metal</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20channels" title=" multiple channels"> multiple channels</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20field" title=" magnetic field"> magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetohydrodynamic" title=" magnetohydrodynamic"> magnetohydrodynamic</a> </p> <a href="https://publications.waset.org/abstracts/25440/magnetohydrodynamic-flows-in-a-conduit-with-multiple-channels-under-a-magnetic-field-applied-perpendicular-to-the-plane-of-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25440.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">281</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">5437</span> Bi-Objective Optimization for Sustainable Supply Chain Network Design in Omnichannel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Veerpaul%20Maan">Veerpaul Maan</a>, <a href="https://publications.waset.org/abstracts/search?q=Gaurav%20Mishra"> Gaurav Mishra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The evolution of omnichannel has revolutionized the supply chain of the organizations by enhancing customer shopping experience. For these organizations need to develop well-integrated multiple distribution channels to leverage the benefits of omnichannel. To adopt an omnichannel system in the supply chain has resulted in structuring and reconfiguring the practices of the traditional supply chain distribution network. In this paper a multiple distribution supply chain network (MDSCN) have been proposed which integrates online giants with a local retailers distribution network in uncertain environment followed by sustainability. To incorporate sustainability, an additional objective function is added to reduce the carbon content through minimizing the travel distance of the product. Through this proposed model, customers are free to access product and services as per their choice of channels which increases their convenience, reach and satisfaction. Further, a numerical illustration is being shown along with interpretation of results to validate the proposed model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20supply%20chain%20network" title="sustainable supply chain network">sustainable supply chain network</a>, <a href="https://publications.waset.org/abstracts/search?q=omnichannel" title=" omnichannel"> omnichannel</a>, <a href="https://publications.waset.org/abstracts/search?q=multiple%20distribution%20supply%20chain%20network" title=" multiple distribution supply chain network"> multiple distribution supply chain network</a>, <a href="https://publications.waset.org/abstracts/search?q=integrate%20multiple%20distribution%20channels" title=" integrate multiple distribution channels"> integrate multiple distribution channels</a> </p> <a href="https://publications.waset.org/abstracts/97719/bi-objective-optimization-for-sustainable-supply-chain-network-design-in-omnichannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97719.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">223</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">5436</span> Determination of Concentrated State Using Multiple EEG Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tae%20Jin%20Choi">Tae Jin Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Ok%20Kim"> Jong Ok Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Sang%20Min%20Jin"> Sang Min Jin</a>, <a href="https://publications.waset.org/abstracts/search?q=Gilwon%20Yoon"> Gilwon Yoon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Analysis of EEG brainwave provides information on mental or emotional states.

A premixed Propane-air mixture was used for the reported experiments. Regarding micro-combustion, flame quenching is considered to be the most crucial problem to overcome first. Experiments were carried out on four channels with different aspect ratios. The results show that at a very low equivalence ratio ϕ=0.4, there is no flame inside the channels. The FREI condition (Flame with repetitive extinction and ignition) was overcome by increasing velocity and by making the channels more in contact with the external heater. The flame tested inside the channels at different locations for V=0.3 m/s or higher below V=0.65 m/s. The effects of equivalence ratio and flow velocity on the characteristics of combustion in the channels were examined. Different ways of flame propagation were observed in the current investigations based on how they appear as planar, concave and convex flames. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flame%20stabilization" title="flame stabilization">flame stabilization</a>, <a href="https://publications.waset.org/abstracts/search?q=combustion" title=" combustion"> combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=flame%20dynamics" title=" flame dynamics"> flame dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=small-scale%20channels" title=" small-scale channels"> small-scale channels</a>, <a href="https://publications.waset.org/abstracts/search?q=external%20heater" title=" external heater"> external heater</a> </p> <a href="https://publications.waset.org/abstracts/166106/flame-dynamics-in-small-scale-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166106.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">228</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">5434</span> Channels Splitting Strategy for Optical Local Area Networks of Passive Star Topology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peristera%20Baziana">Peristera Baziana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a network configuration for a WDM LANs of passive star topology that assume that the set of data WDM channels is split into two separate sets of channels, with different access rights over them.

MIMO system uses multiple transmitting and receiving antennas with different coding techniques to either enhance the transmission diversity or spatial multiplexing gain. Utilizing alamouti algorithm were the same information transmitted over multiple antennas at different time intervals and then collected again at the receivers to minimize the probability of error, combat fading and thus improve the received signal to noise ratio. While utilizing V-BLAST algorithm, the transmitted signals are divided into different transmitting channels and transferred over the channel to be received by different receiving antennas to increase the transmitted data rate and achieve higher throughput. The paper provides a study of different diversity gain coding schemes and spatial multiplexing coding for MIMO systems. A comparison of various channels' estimation and equalization techniques are given. The simulation is implemented using MATLAB, and the results had shown the performance of transmission models under different channel environments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIMO%20communication" title="MIMO communication">MIMO communication</a>, <a href="https://publications.waset.org/abstracts/search?q=BER" title=" BER"> BER</a>, <a href="https://publications.waset.org/abstracts/search?q=space%20codes" title=" space codes"> space codes</a>, <a href="https://publications.waset.org/abstracts/search?q=channels" title=" channels"> channels</a>, <a href="https://publications.waset.org/abstracts/search?q=alamouti" title=" alamouti"> alamouti</a>, <a href="https://publications.waset.org/abstracts/search?q=V-BLAST" title=" V-BLAST"> V-BLAST</a> </p> <a href="https://publications.waset.org/abstracts/82337/performance-evaluation-of-mimo-ofdm-communication-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82337.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">175</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">5431</span> Analytical Solution of Specific Energy Equation in Exponential Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulrahman%20Abdulrahman">Abdulrahman Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The specific energy equation has many applications in practical channels, such as exponential channels. In this paper, the governing equation of alternate depth ratio for exponential channels, in general, was investigated towards obtaining analytical solution for the alternate depth ratio in three exponential channel shapes, viz., rectangular, triangular, and parabolic channels. The alternate depth ratio for rectangular channels is quadratic; hence it is very simple to solve. While for parabolic and triangular channels, the alternate depth ratio is cubic and quartic equations, respectively, analytical solution for these equations may be achieved easily for a given Froud number. Different examples are solved to prove the efficiency of the proposed solution. Such analytical solution can be easily used in natural rivers and most of practical channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternate%20depth" title="alternate depth">alternate depth</a>, <a href="https://publications.waset.org/abstracts/search?q=analytical%20solution" title=" analytical solution"> analytical solution</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20energy" title=" specific energy"> specific energy</a>, <a href="https://publications.waset.org/abstracts/search?q=parabolic%20channel" title=" parabolic channel"> parabolic channel</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangular%20channel" title=" rectangular channel"> rectangular channel</a>, <a href="https://publications.waset.org/abstracts/search?q=triangular%20channel" title=" triangular channel"> triangular channel</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20channel%20flow" title=" open channel flow"> open channel flow</a> </p> <a href="https://publications.waset.org/abstracts/121104/analytical-solution-of-specific-energy-equation-in-exponential-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121104.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">198</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">5430</span> Privacy Protection Principles of Omnichannel Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Renata%20Mekovec">Renata Mekovec</a>, <a href="https://publications.waset.org/abstracts/search?q=Dijana%20Peras"> Dijana Peras</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruben%20Picek"> Ruben Picek</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The advent of the Internet, mobile devices and social media is revolutionizing the experience of retail customers by linking multiple sources through various channels. Omnichannel retailing is a retailing that combines multiple channels to allow customers to seamlessly leverage all the distribution information online and offline while shopping. Therefore, today data are an asset more critical than ever for all organizations. Nonetheless, because of its heterogeneity through platforms, developers are currently facing difficulties in dealing with personal data. Considering the possibilities of omnichannel communication, this paper presents channel categorization that could enhance the customer experience of omnichannel center called hyper center. The purpose of this paper is fundamentally to describe the connection between the omnichannel hyper center and the customer, with particular attention to privacy protection. The first phase was finding the most appropriate channels of communication for hyper center. Consequently, a selection of widely used communication channels has been identified and analyzed with regard to the effect requirements for optimizing user experience. The evaluation criteria are divided into 3 groups: general, user profile and channel options. For each criterion the weight of importance for omnichannel communication was defined.

A review of the state of the art of convective boiling studies in mini-channels and conventional channels for operating with CO₂ was carried out, with special attention to the flow patterns and pressure drop maps in single-phase and two-phase flows. To carry out an experimental analysis of the convective boiling of CO₂, a properly instrumented experimental bench was built, which allows a parametric analysis for different thermodynamic conditions, such as mass velocities between 200 and 1300 kg/(m².s), pressures between 20 and 70bar, temperature monitoring at the entrance of the mini-channels, heat flow and pressure drop in the test section. The visualization of flow patterns was possible with the use of a high-speed CMOS camera. The results obtained are in line with those found in the literature, both for flow patterns and for the heat transfer coefficient. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title="carbon dioxide">carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=convective%20boiling" title=" convective boiling"> convective boiling</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82" title=" CO₂"> CO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=mini-channels" title=" mini-channels"> mini-channels</a> </p> <a href="https://publications.waset.org/abstracts/136203/convective-boiling-of-co2-in-macro-and-mini-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/136203.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">164</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">5428</span> Sum Capacity with Regularized Channel Inversion in Multi-Antenna Downlink Systems under Equal Power Constraint</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Attaullah%20Khawaja">Attaullah Khawaja</a>, <a href="https://publications.waset.org/abstracts/search?q=Amna%20Shabbir"> Amna Shabbir </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Channel inversion is one of the simplest techniques for multiuser downlink systems with single-antenna users.

Through the application of conformal cooling channels fabricated via metal additive manufacturing, part distortion, warpage can be greatly reduced and cycle time can be greatly shortened. However, the properties of additively manufactured conformal cooling channels are quite different from conventional drilling processes such as the poorer dimensional accuracy and larger surface roughness. These features have significant influences on its cooling performance. In this study, test molds with the cooling channel diameters of φ2 mm, φ3 mm and φ4 mm were fabricated via selective laser melting and conventional drilling process respectively. A test system was designed and manufactured to measure the pressure difference between the channel inlet and outlet, the coolant flow rate and the temperature variation during the heating process. It was found that the cooling performance of SLM-fabricated channels was poorer than drilled cooling channels due to the smaller sectional area of cooling channels resulted from the low dimensional accuracy and the unmolten particles adhered to the channel surface. Theoretical models were established to determine the friction factor and heat transfer coefficient of SLM-fabricated cooling channels. These findings may provide guidance to the design of conformal cooling channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conformal%20cooling%20channels" title="conformal cooling channels">conformal cooling channels</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling%20performance" title=" cooling performance"> cooling performance</a>, <a href="https://publications.waset.org/abstracts/search?q=injection%20molding" title=" injection molding"> injection molding</a> </p> <a href="https://publications.waset.org/abstracts/102200/investigation-on-the-cooling-performance-of-cooling-channels-fabricated-via-selective-laser-melting-for-injection-molding" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102200.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">150</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">5426</span> Performance Analysis of M-Ary Pulse Position Modulation in Multihop Multiple Input Multiple Output-Free Space Optical System over Uncorrelated Gamma-Gamma Atmospheric Turbulence Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hechmi%20Saidi">Hechmi Saidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Noureddine%20Hamdi"> Noureddine Hamdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The performance of Decode and Forward (DF) multihop Free Space Optical ( FSO) scheme deploying Multiple Input Multiple Output (MIMO) configuration under Gamma-Gamma (GG) statistical distribution, that adopts M-ary Pulse Position Modulation (MPPM) coding, is investigated.

The deployment of massive multiple-input-multiple-output technology guarantees broadband wireless networks with the use of base station antenna arrays to serve a large number of users on the same frequency and time-slot channels. In this work, we evaluate the performance of massive multiple-input-multiple-output systems (MIMO) systems in 5<sup>th</sup> generation cellular networks in terms of capacity and bit error rate. Several cases were considered and analyzed to compare the performance of massive MIMO systems while varying the number of antennas at both transmitting and receiving ends. We found that, unlike classical MIMO systems, reducing the number of transmit antennas while increasing the number of antennas at the receiver end provides a better solution to performance enhancement. In addition, enhanced orthogonal frequency division multiplexing and beam division multiple access schemes further improve the performance of massive MIMO systems and make them more reliable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=beam%20division%20multiple%20access" title="beam division multiple access">beam division multiple access</a>, <a href="https://publications.waset.org/abstracts/search?q=D2D%20communication" title=" D2D communication"> D2D communication</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20OFDM" title=" enhanced OFDM"> enhanced OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=fifth%20generation%20broadband" title=" fifth generation broadband"> fifth generation broadband</a>, <a href="https://publications.waset.org/abstracts/search?q=massive%20MIMO" title=" massive MIMO"> massive MIMO</a> </p> <a href="https://publications.waset.org/abstracts/96696/performance-analysis-in-5th-generation-massive-multiple-input-multiple-output-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96696.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">258</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">5424</span> Security Over OFDM Fading Channels with Friendly Jammer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munnujahan%20Ara">Munnujahan Ara</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we investigate the effect of friendly jamming power allocation strategies on the achievable average secrecy rate over a bank of parallel fading wiretap channels.

As a result, expensive dredging may need to maintain the water depth required for navigation. In our study, we conduct a series of experiments to investigate the characteristics of density-induced flow in the estuarine navigation channels under different density gradients. Empirical equations between density flow and salinity gradient were derived. Effects of coastal structures for regulating navigation channel on density-induced flow have also been investigated. Results will be very helpful for improving the understanding of the characteristics of density-induced flow in estuarine navigation channels. The results will also provide technical support for cost-effective waterway regulation and management to maintain coastal and estuarine navigation channels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20flow" title="density flow">density flow</a>, <a href="https://publications.waset.org/abstracts/search?q=estuarine" title=" estuarine"> estuarine</a>, <a href="https://publications.waset.org/abstracts/search?q=navigation%20channel" title=" navigation channel"> navigation channel</a>, <a href="https://publications.waset.org/abstracts/search?q=structure" title=" structure"> structure</a> </p> <a href="https://publications.waset.org/abstracts/119059/effects-of-structure-on-density-induced-flow-in-coastal-and-estuarine-navigation-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119059.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">258</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">5418</span> Using Data-Driven Model on Online Customer Journey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ing-Jen%20Hung">Ing-Jen Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Tzu-Chien%20Wang"> Tzu-Chien Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, customers can interact with firms through miscellaneous online ads on different channels easily.

Perhaps YouTube is one of the most important platforms in which the Algerian audience resides, as Alexa, which is one of the most important tools for providing usage statistics, indicated that the number of Algerian audience views of this site has exceeded 11 million views per month, and many Algerian content makers have initiated the creation of Sports channels in order to achieve profit goals. They also seek through it to market professional footballers abroad, in addition to influencing the opinions of fans towards them. This scene directs us to study the extent to which these channels contribute to discovering professional players, marketing to them, and protecting them from negative criticism. We also aim to know the extent of the influence of the content makers of these channels on the Algerian audience and to raise their awareness of the positive support of the players, regardless of their level of performance. To collect the necessary data, a descriptive study was conducted in which interview and observation were adopted as two basic tools.

Traditional seepage-abatement technologies are very expensive. The goals of this work were to quantify water loss in unlined channels and select reaches to evaluate the use of linear anionic polyacrylamide (LA-PAM) to reduce seepage losses. The study was carried out in Maule Region, central area of Chile. Water users indicated reaches with potential seepage losses, 45 km of channels in total, whose flow varied between 1.07 and 23.6 m³ s⁻¹. According to seepage measurements, 4 reaches of channels, 4.5 km in total, were selected for LA-PAM application. One to 4 LA-PAM applications were performed at rates of 11 kg ha⁻¹, considering wet perimeter area as basis of calculation. Large channels were used to allow motorboat moving against the current to carry-out LA-PAM application. For applications, a seeder machine was used to evenly distribute granulated polymer on water surface. Water flow was measured (StreamPro ADCP) upstream and downstream in selected reaches, to estimate seepage losses before and after LA-PAM application. Weekly measurements were made to quantify treatment effect and duration. In each case, water turbidity and temperature were measured. Channels showed variable losses up to 13.5%. Channels showing water gains were not treated with PAM. In all cases, LA-PAM effect was positive, achieving average loss reductions of 8% to 3.1%. Water loss was confirmed and it was possible to reduce seepage through LA-PAM applications provided that losses were known and correctly determined when applying the polymer. This could allow increasing irrigation security in critical periods, especially under drought conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=canal%20seepage" title="canal seepage">canal seepage</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation" title=" irrigation"> irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=polyacrylamide" title=" polyacrylamide"> polyacrylamide</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20management" title=" water management"> water management</a> </p> <a href="https://publications.waset.org/abstracts/75098/quantification-of-effect-of-linear-anionic-polyacrylamide-on-seepage-in-irrigation-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75098.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">174</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">5414</span> Isolation and Characterization of the First Known Inhibitor Cystine Knot Peptide in Sea Anemone: Inhibitory Activity on Acid-Sensing Ion Channels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Armando%20A.%20Rodr%C3%ADguez">Armando A.

These proteins belong to the ENaC/degenerin superfamily of sodium channels. ASICs are involved in sensory perception, synaptic plasticity, learning, memory formation, cell migration and proliferation, nociception, and neurodegenerative disorders, among other processes; therefore those molecules that specifically target these channels are of growing pharmacological and biomedical interest. Sea anemones produce a large variety of ion channels peptide toxins; however, those acting on ligand-gated ion channels, such as Glu-gated, Ach-gated ion channels, and acid-sensing ion channels (ASICs), remain barely explored. The peptide PhcrTx1 is the first compound characterized from the sea anemone Phymanthus crucifer, and it constitutes a novel ASIC inhibitor. This peptide was purified by chromatographic techniques and pharmacologically characterized on acid-sensing ion channels of mammalian neurons using patch-clamp techniques. PhcrTx1 inhibited ASIC currents with an IC50 of 100 nM. Edman degradation yielded a sequence of 32 amino acids residues, with a molecular mass of 3477 Da by MALDI-TOF. No similarity to known sea anemone peptides was found in protein databases. The computational analysis of Cys-pattern and secondary structure arrangement suggested that this is a structurally ICK (Inhibitor Cystine Knot)-type peptide, a scaffold that had not been found in sea anemones but in other venomous organisms. These results show that PhcrTx1 represents the first member of a new structural group of sea anemones toxins acting on ASICs. Also, this peptide constitutes a novel template for the development of drugs against pathologies related to ASICs function. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=animal%20toxin" title="animal toxin">animal toxin</a>, <a href="https://publications.waset.org/abstracts/search?q=inhibitor%20cystine%20knot" title=" inhibitor cystine knot"> inhibitor cystine knot</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20channel" title=" ion channel"> ion channel</a>, <a href="https://publications.waset.org/abstracts/search?q=sea%20anemone" title=" sea anemone"> sea anemone</a> </p> <a href="https://publications.waset.org/abstracts/66405/isolation-and-characterization-of-the-first-known-inhibitor-cystine-knot-peptide-in-sea-anemone-inhibitory-activity-on-acid-sensing-ion-channels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66405.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">310</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">5413</span> A Review of the Relation between Thermofludic Properties of the Fluid in Micro Channel Based Cooling Solutions and the Shape of Microchannel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurjit%20Singh">Gurjit Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Gurmail%20Singh"> Gurmail Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The shape of microchannels in microchannel heat sinks can have a significant impact on both heat transfer and fluid flow properties. Heat Transfer, pressure drop, and Some effects of microchannel shape on these properties. The shape of microchannels can affect the heat transfer performance of microchannel heat sinks. Channels with rectangular or square cross-sections typically have higher heat transfer coefficients compared to circular channels. This is because rectangular or square channels have a larger wetted perimeter per unit cross-sectional area, which enhances the heat transfer from the fluid to the channel walls. The shape of microchannels can also affect the pressure drop across the heat sink. Channels with a rectangular cross-section usually have higher pressure drop than circular channels. This is because the corners of rectangular channels create additional flow resistance, which leads to a higher pressure drop. Overall, the shape of microchannels in microchannel heat sinks can have a significant impact on the heat transfer and fluid flow properties of the heat sink. The optimal shape of microchannels depends on the specific application and the desired balance between heat transfer performance and pressure drop. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=microchannel%20heat%20sink" title=" microchannel heat sink"> microchannel heat sink</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20drop" title=" pressure drop"> pressure drop</a>, <a href="https://publications.waset.org/abstracts/search?q=chape%20of%20microchannel" title=" chape of microchannel"> chape of microchannel</a> </p> <a href="https://publications.waset.org/abstracts/163605/a-review-of-the-relation-between-thermofludic-properties-of-the-fluid-in-micro-channel-based-cooling-solutions-and-the-shape-of-microchannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163605.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">90</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">5412</span> Thermal Hydraulic Analysis of Sub-Channels of Pressurized Water Reactors with Hexagonal Array: A Numerical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Asif%20Ullah">Md.

At a steady state, the temperature of outer surface of the cladding of fuel rod is kept about 1200°C. The temperature of this isothermal surface is taken as boundary condition for simulation. Water with temperature of 290°C is given as a coolant inlet to the primary water circuit which is pressurized upto 157 bar. Turbulent flow of pressurized water is used for heat removal. In 2-D model, temperature, velocity, pressure and Nusselt number distributions are simulated in a vertical sectional plane through the sub-channels of a hexagonal fuel rod assembly. Temperature, Nusselt number and Y-component of convective heat flux along a line in this plane near the end of fuel rods are plotted for different Reynold’s number. A comparison between X-component and Y-component of convective heat flux in this vertical plane is analyzed. Hexagonal fuel rod assembly has three types of sub-channels according to geometrical shape whose boundary conditions are different too. In 3-D model, temperature, velocity, pressure, Nusselt number, total heat flux magnitude distributions for all the three sub-channels are studied for a suitable Reynold’s number. A horizontal sectional plane is taken from each of the three sub-channels to study temperature, velocity, pressure, Nusselt number and convective heat flux distribution in it. Greater values of temperature, Nusselt number and Y-component of convective heat flux are found for greater Reynold’s number. X-component of convective heat flux is found to be non-zero near the bottom of fuel rod and zero near the end of fuel rod. This indicates that the convective heat transfer occurs totally along the direction of flow near the outlet. As, length to radius ratio of sub-channels is very high, simulation for a short length of the sub-channels are done for graphical interface advantage. For the simulations, Turbulent Flow (K-Є ) module and Heat Transfer in Fluids (ht) module of COMSOL MULTIPHYSICS 5.0 are used. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sub-channels" title="sub-channels">sub-channels</a>, <a href="https://publications.waset.org/abstracts/search?q=Reynold%E2%80%99s%20number" title=" Reynold’s number"> Reynold’s number</a>, <a href="https://publications.waset.org/abstracts/search?q=Nusselt%20number" title=" Nusselt number"> Nusselt number</a>, <a href="https://publications.waset.org/abstracts/search?q=convective%20heat%20transfer" title=" convective heat transfer"> convective heat transfer</a> </p> <a href="https://publications.waset.org/abstracts/40384/thermal-hydraulic-analysis-of-sub-channels-of-pressurized-water-reactors-with-hexagonal-array-a-numerical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40384.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">360</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">5411</span> Improved Accuracy of Ratio Multiple Valuation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julianto%20Agung%20Saputro">Julianto Agung Saputro</a>, <a href="https://publications.waset.org/abstracts/search?q=Jogiyanto%20Hartono"> Jogiyanto Hartono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Multiple valuation is widely used by investors and practitioners but its accuracy is questionable.

The objective of the present study is to measure the drag and lift on such submerged vanes in open channels. Experiments were performed and the data collected have been presented and analyzed.

We propose self-organization of unused resources usually excessive unused channels of neighbouring cells with densely populated cells to reduce handover failure rates. The neighboring cells share unused channels after fulfilling some conditional candidature criterion using threshold values so that they are not suffered themselves for starvation of channels in case of any abrupt change in traffic pattern. The cells are classified as ‘red’, ‘yellow’, or ‘green’, as per the available channels in cell which is governed by traffic pattern and thresholds. To combat the deficiency of channels in red cell, migration of unused channels from under-loaded cells, hierarchically from the qualified candidate neighboring cells is explored. The resources are returned back when the congested cell is capable of self-contained traffic management. In either of the cases conditional sharing of resources is executed for enhanced traffic management so that User Equipment (UE) is provided uninterrupted services with high Quality of Service (QoS). The fuzzy logic-based simulation results show that the proposed algorithm is efficiently in coincidence with improved successful handoffs. <p class="card-text"><strong>Keywords:</strong> <a
