Both ends of the channel are kept at a constant temperature which may lead to significant changes in electrophoretic migration speed. A mathematical model based on Nernst-Planck equations for transport of ions coupled with the equation for temperature field is considered. In addition, the charge conservation equations govern the potential field due to the external electric field. We have computed the equations for ion transport, potential and temperature in a coupled manner through the finite volume method. The diffusive terms are discretized via central difference scheme, while QUICK (Quadratic Upwind Interpolation Convection Kinematics) scheme is used to discretize the convective terms. We find that the thermal end effect has significant effect on the isotachophoretic (ITP) migration speed of the analyte. Our result shows that the ITP velocity for temperature dependent case no longer varies linearly with the applied electric field. A detailed analysis has been made to provide a range of the key parameters to minimize the Joule heating effect on ITP transport of analytes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=finite%20volume%20method" title="finite volume method">finite volume method</a>, <a href="https://publications.waset.org/abstracts/search?q=isotachophoresis" title=" isotachophoresis"> isotachophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=QUICK%20scheme" title=" QUICK scheme"> QUICK scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20effect" title=" thermal effect"> thermal effect</a> </p> <a href="https://publications.waset.org/abstracts/63435/thermal-end-effect-on-the-isotachophoretic-separation-of-analytes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63435.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">272</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">1814</span> Advanced CoMP Scheme for LTE-based V2X System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Su-Hyun%20Jung">Su-Hyun Jung</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Su%20Ryu"> Young-Su Ryu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Jun%20Kim"> Yong-Jun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a highly efficient coordinated multiple-point (CoMP) scheme for vehicular communication is proposed.

Blom’s scheme is a symmetric threshold key exchange protocol in cryptography. The scheme was proposed by the Swedish cryptographer Rolf Blom. In this kind of scheme, trusted authority gives each user a secret key and a public identifier, which enables any two users to create independently a shared key for communicating between each other. However, if an attacker can compromise the keys of at least Known numbers of users, he can break the scheme and reconstruct every shared key. In this paper generalized Blom’s Scheme by multivariate Lagrange interpolation formula. This scheme is a form of threshold secret sharing scheme. In this new scheme, the amount of information transmitted by the trusted authority is independent of the numbers of users. In addition, this scheme is unconditionally secure against any individual user. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=key%20predistribution" title="key predistribution">key predistribution</a>, <a href="https://publications.waset.org/abstracts/search?q=blom%E2%80%99s%20scheme" title=" blom’s scheme"> blom’s scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=secret%20sharing" title=" secret sharing"> secret sharing</a>, <a href="https://publications.waset.org/abstracts/search?q=unconditional%20secure" title=" unconditional secure"> unconditional secure</a> </p> <a href="https://publications.waset.org/abstracts/39358/generalization-of-blom-key-predistribution-scheme" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39358.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">437</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">1812</span> Comparison Analysis of CFD Turbulence Fluid Numerical Study for Quick Coupling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=JoonHo%20Lee">JoonHo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=KyoJin%20An"> KyoJin An</a>, <a href="https://publications.waset.org/abstracts/search?q=JunSu%20Kim"> JunSu Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Young-Chul%20Park"> Young-Chul Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, the fluid flow characteristics and performance numerical study through CFD model of the Non-split quick coupling for flow control in hydraulic system equipment for the aerospace business group focused to predict.

However, the performance of communication is not sufficiently improved since the distance between each base station and a user is still distant.

To validate the performance of the OR scheme, we derive the average signal-to-interference plus noise ratio (SINR) and the average capacity and compare it with the conventional universal frequency reuse factor (UFRF).

Therefore the proposed detection scheme can be efficiently used in wireless communication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=MIMO-OFDM" title="MIMO-OFDM">MIMO-OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=V-BLAST" title=" V-BLAST"> V-BLAST</a>, <a href="https://publications.waset.org/abstracts/search?q=QR-decomposition" title=" QR-decomposition"> QR-decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=QRDM" title=" QRDM"> QRDM</a>, <a href="https://publications.waset.org/abstracts/search?q=DFE" title=" DFE"> DFE</a>, <a href="https://publications.waset.org/abstracts/search?q=iterative%20scheme" title=" iterative scheme"> iterative scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=channel%20condition" title=" channel condition"> channel condition</a> </p> <a href="https://publications.waset.org/abstracts/3522/efficient-iterative-v-blast-detection-technique-in-wireless-communication-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3522.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">530</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">1805</span> Application of the Finite Window Method to a Time-Dependent Convection-Diffusion Equation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raoul%20Ouambo%20Tobou">Raoul Ouambo Tobou</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexis%20Kuitche"> Alexis Kuitche</a>, <a href="https://publications.waset.org/abstracts/search?q=Marcel%20Edoun"> Marcel Edoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The FWM (Finite Window Method) is a new numerical meshfree technique for solving problems defined either in terms of PDEs (Partial Differential Equation) or by a set of conservation/equilibrium laws. The principle behind the FWM is that in such problem each element of the concerned domain is interacting with its neighbors and will always try to adapt to keep in equilibrium with respect to those neighbors. This leads to a very simple and robust problem solving scheme, well suited for transfer problems. In this work, we have applied the FWM to an unsteady scalar convection-diffusion equation. Despite its simplicity, it is well known that convection-diffusion problems can be challenging to be solved numerically, especially when convection is highly dominant. This has led researchers to set the scalar convection-diffusion equation as a benchmark one used to analyze and derive the required conditions or artifacts needed to numerically solve problems where convection and diffusion occur simultaneously. We have shown here that the standard FWM can be used to solve convection-diffusion equations in a robust manner as no adjustments (Upwinding or Artificial Diffusion addition) were required to obtain good results even for high Peclet numbers and coarse space and time steps. A comparison was performed between the FWM scheme and both a first order implicit Finite Volume Scheme (Upwind scheme) and a third order implicit Finite Volume Scheme (QUICK Scheme). The results of the comparison was that for equal space and time grid spacing, the FWM yields a much better precision than the used Finite Volume schemes, all having similar computational cost and conditioning number. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Finite%20Window%20Method" title="Finite Window Method">Finite Window Method</a>, <a href="https://publications.waset.org/abstracts/search?q=Convection-Diffusion" title=" Convection-Diffusion"> Convection-Diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=Numerical%20Technique" title=" Numerical Technique"> Numerical Technique</a>, <a href="https://publications.waset.org/abstracts/search?q=Convergence" title=" Convergence"> Convergence</a> </p> <a href="https://publications.waset.org/abstracts/66015/application-of-the-finite-window-method-to-a-time-dependent-convection-diffusion-equation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66015.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">332</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">1804</span> Efficient Variable Modulation Scheme Based on Codebook in the MIMO-OFDM System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yong-Jun%20Kim">Yong-Jun Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hyun%20Ro"> Jae-Hyun Ro</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang-Bin%20Ha"> Chang-Bin Ha</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyoung-Kyu%20Song"> Hyoung-Kyu Song</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Because current wireless communication requires high reliability in a limited bandwidth environment, this paper proposes the variable modulation scheme based on the codebook.

The results indicated that the net farm income of the commercial agricultural credit scheme beneficiaries increases from N15,006,352.00 before scheme to N24,862,585.00 after the first and the second phases of the scheme. There was also an increase in the net farm income of the non-beneficiaries from N9, 670,385.40 to N14, 391,469.00 during the scheme.

Two cellular base stations (CBSs) communicating with a user in the cell edge use cooperative transmission scheme in the conventional scheme. In the case that the distance between two CBSs and the user is distant, the conventional scheme does not guarantee the quality of the communication because the channel condition is bad. Therefore, if the distance between CBSs and a user is distant, the performance of the conventional scheme is decreased. Also, the bad channel condition has bad effects on the performance. The proposed scheme uses two relays to communicate well with CBSs when the channel condition between CBSs and the user is poor. Using the relay in the high attenuation environment can obtain both advantages of the high bit error rate (BER) and throughput performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cooperative%20communications" title="cooperative communications">cooperative communications</a>, <a href="https://publications.waset.org/abstracts/search?q=diversity%20gain" title=" diversity gain"> diversity gain</a>, <a href="https://publications.waset.org/abstracts/search?q=OFDM" title=" OFDM"> OFDM</a>, <a href="https://publications.waset.org/abstracts/search?q=interworking%20system" title=" interworking system"> interworking system</a> </p> <a href="https://publications.waset.org/abstracts/32055/improved-performance-of-cooperative-scheme-in-the-cellular-and-broadcasting-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32055.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">576</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">1793</span> Addressing Scheme for IOT Network Using IPV6 </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Zormati">H.

Cooperative communication can achieve reliability and lower power than multiple-input multiple-output (MIMO) system. Cooperative communication increases the reliability with low power, but decreases a throughput. It has a weak point that the communication throughput is decreased. In this paper, a novel scheme is proposed to increase the communication throughput. The novel scheme is a transmission structure that increases transmission rate. And a decoding scheme according to the novel transmission structure is proposed.

E-government has moved from just providing electronic information to citizens and customers alike to serving their needs. In developing countries like Nigeria, the enablement of e-government is being used as an anti-corruption tool. The introduction of the Bank verification number (BVN) scheme by the Central Bank of Nigeria, has helped the government in not just saving money but also protecting customer’s transaction and enhancing confidence in the banking sector. This has helped curtail the high rate of cyber and financial crime that has been part of the system. The use of BVN as an anti-corruption tool in Nigeria came at a time there was need for openness, accountability, and discipline, after years of robbing the treasury and recklessness in handling finances. As there has not been a defined method for measuring the strength or success of e-government development, in this case BVN, in Nigeria, progress will remain at the same level. The implementation strategy of the BVN in Nigeria has mostly been a quick fix, quick win solution. In fact, there is little or no indication to show evidence of a framework for e-government. Like other leading countries, there is the need for proper implementation of strategy and framework especially towards a customer orientated process, which will accommodate every administrative body of the government institution including private business rather than focusing on a non-flexible organisational structure. The development of e-government must have a strategy and framework for it to work, and this strategy must enclose every public administration and will not be limited to any individual bodies or organization. A defined framework or monitoring method must be put in place to help evaluate and benchmark government development in e-government. This framework must follow the same concept or principles. In censorious analyses of the existing methods, this paper will denote areas that must be included in the existing approach to be able to channel e-government development towards its defined strategic objectives. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bank%20Verification%20No%20%28BVN%29" title="Bank Verification No (BVN)">Bank Verification No (BVN)</a>, <a href="https://publications.waset.org/abstracts/search?q=quick-fix" title=" quick-fix"> quick-fix</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-corruption" title=" anti-corruption"> anti-corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=quick-win" title=" quick-win"> quick-win</a> </p> <a href="https://publications.waset.org/abstracts/76472/e-government-development-in-nigeria-bank-verification-no-an-anti-corruption-tool" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/76472.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">160</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">1788</span> Compact Finite Difference Schemes for Fourth Order Parabolic Partial Differential Equations </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sufyan%20Muhammad">Sufyan Muhammad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, in achieving highly efficient but at the same time highly accurate solutions has become the major target of numerical analyst community.
