This platform gives better predictions of the effects of temperature distribution of the sugarcane problem. This work presented parallel overheads with overlapping communication and communication across parallel computers with numerical results across different block sizes with scalability.

However, since the efficiency of parallelization is much lower than that of FDTD, PSTD is not a useful method for a large-scale electromagnetic simulation in a parallel platform. In this paper, we propose the parallelization technique of the hybrid PSTD-FDTD (HPF) method which simultaneously possesses the efficient parallelizability of FDTD and the quick speed and low memory requirement of PSTD. Parallelization cost of the HPF method is exactly the same as the parallel FDTD, but still, it occupies much less memory space and has faster operation speed than the parallel FDTD. Experiments in distributed memory systems have shown that the parallel HPF method saves up to 96% of the operation time and reduces 84% of the memory requirement. Also, by combining the OpenMP library to the MPI library, we further reduced the operation time of the parallel HPF method by 50%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FDTD" title="FDTD">FDTD</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid" title=" hybrid"> hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=MPI" title=" MPI"> MPI</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenMP" title=" OpenMP"> OpenMP</a>, <a href="https://publications.waset.org/abstracts/search?q=PSTD" title=" PSTD"> PSTD</a>, <a href="https://publications.waset.org/abstracts/search?q=parallelization" title=" parallelization"> parallelization</a> </p> <a href="https://publications.waset.org/abstracts/104171/parallelizing-the-hybrid-pseudo-spectral-time-domainfinite-difference-time-domain-algorithms-for-the-large-scale-electromagnetic-simulations-using-massage-passing-interface-library" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104171.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19808</span> Parallel PRBS Generation and Parallel BER Tester for 8-Gbps On-chip Interconnection Testing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Bin">Zhao Bin</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Dan%20Lei"> Yan Dan Lei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, a multi-pattern parallel PRBS generator and a dedicated parallel BER tester is proposed for the 8-Gbps On-chip interconnection testing.

Plots generated by the test system are compared with those generated by XDAT, a software implementing traditional parallel coordinates. Traditional parallel coordinate plots can be cluttered when the number of data points is large or when the dimensionality of the data is high. PCoSS plots display multivariate data on a 3D spiral surface and allow users to see the whole picture of high-dimensional data with less cluttering. Taking advantage of the 3D display environment in PCoSS, users can further reduce cluttering by zooming into an axis of interest for a closer view or by moving vantage points and by reorienting the viewing angle to obtain a desired view of the plots. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20computer%20interaction" title="human computer interaction">human computer interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20coordinates" title=" parallel coordinates"> parallel coordinates</a>, <a href="https://publications.waset.org/abstracts/search?q=spiral%20surface" title=" spiral surface"> spiral surface</a>, <a href="https://publications.waset.org/abstracts/search?q=visualization" title=" visualization"> visualization</a> </p> <a href="https://publications.waset.org/abstracts/193466/parallel-coordinates-on-a-spiral-surface-for-visualizing-high-dimensional-data" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193466.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">11</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">19806</span> 4-DOFs Parallel Mechanism for Minimally Invasive Robotic Surgery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khalil%20Ibrahim">Khalil Ibrahim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ramadan"> Ahmed Ramadan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Fanni"> Mohamed Fanni</a>, <a href="https://publications.waset.org/abstracts/search?q=Yo%20Kobayashi"> Yo Kobayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Abo-Ismail"> Ahmed Abo-Ismail</a>, <a href="https://publications.waset.org/abstracts/search?q=Masakatus%20G.%20Fujie"> Masakatus G.

The proposed mechanism, 2-PUU_2-PUS, is designed based on the screw theory and the parallel virtual chain type synthesis method. Based on the structure analysis of the 4-DOF parallel mechanism, the inverse position equation is studied using the inverse analysis theory of kinematics. The design and the stress analysis of the mechanism are investigated using SolidWorks software. The virtual prototype of the parallel mechanism is constructed, and the dynamic simulation is performed using ADAMS TM software. The system model utilizing PID and PI controllers has been built using MATLAB software. A more realistic simulation in accordance with a given bending angle and point to point control is implemented by the use of both ADAMS/MATLAB software. The simulation results showed that this control method has solved the coordinate control for the 4-DOF parallel manipulator so that each output is feedback to the four driving rods. From the results, the tracking performance is achieved. Other control techniques, such as intelligent ones, are recommended to improve the tracking performance and reduce the numerical truncation error. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20mechanisms" title="parallel mechanisms">parallel mechanisms</a>, <a href="https://publications.waset.org/abstracts/search?q=medical%20robotics" title=" medical robotics"> medical robotics</a>, <a href="https://publications.waset.org/abstracts/search?q=tracjectory%20control" title=" tracjectory control"> tracjectory control</a>, <a href="https://publications.waset.org/abstracts/search?q=virtual%20chain%20type%20synthesis%20method" title=" virtual chain type synthesis method"> virtual chain type synthesis method</a> </p> <a href="https://publications.waset.org/abstracts/30373/4-dofs-parallel-mechanism-for-minimally-invasive-robotic-surgery" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30373.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">468</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">19805</span> A Practical Protection Method for Parallel Transmission-Lines Based on the Fault Travelling-Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Reza%20Ebrahimi">Mohammad Reza Ebrahimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In new restructured power systems, swift fault detection is very important.

The equivalent moment of inertia, damping and driving force/torque variation of offshore 2-HUS/U parallel platform were analyzed. A numerical example shows that, for parallel platform of given motion, system’s equivalent inertia changes 1.25 times maximally. During the movement of platform, they change dramatically with the system configuration and have coupling characteristics. The maximum equivalent drive torque is 800 N. At the same time, the curve of platform’s driving force/torque is smooth and has good sine features.

The method employs eigenvalues of a characteristic matrix formed by appropriate time-space FD stencils. Since MFD runs for different modes are totally independent of each other, MFDM can easily be parallelized while considerable simplicity in parallel-algorithm is also achieved. There is no requirement to any domain-decomposition procedure and inter-core data exchange. More important is the possibility to skip processing of less-significant modes, which enables one to adjust the procedure up to the level of accuracy needed. Thus, in addition to considerable ease of parallel programming, computation and storage costs are significantly reduced. The method is qualified for its efficiency by some numerical examples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Finite%20Difference%20Method" title="Finite Difference Method">Finite Difference Method</a>, <a href="https://publications.waset.org/abstracts/search?q=Graphics%20Processing%20Unit%20%28GPU%29" title=" Graphics Processing Unit (GPU)"> Graphics Processing Unit (GPU)</a>, <a href="https://publications.waset.org/abstracts/search?q=Message%20Passing%20Interface%20%28MPI%29" title=" Message Passing Interface (MPI)"> Message Passing Interface (MPI)</a>, <a href="https://publications.waset.org/abstracts/search?q=Modal" title=" Modal"> Modal</a>, <a href="https://publications.waset.org/abstracts/search?q=Wave%20propagation" title=" Wave propagation"> Wave propagation</a> </p> <a href="https://publications.waset.org/abstracts/46212/modal-fdtd-method-for-wave-propagation-modeling-customized-for-parallel-computing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46212.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">296</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">19802</span> Trajectory Tracking of a Redundant Hybrid Manipulator Using a Switching Control Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atilla%20Bayram">Atilla Bayram</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the trajectory tracking control of a spatial redundant hybrid manipulator.

These three modules constitute totally 7-DOF hybrid (parallel-parallel) redundant spatial manipulator. The forward kinematics equations of this manipulator are obtained, then, according to these equations, the inverse kinematics is solved based on an optimization with the joint limit avoidance. The dynamic equations are formed by using virtual work method. In order to test the performance of the redundant manipulator and the controllers presented, two different desired trajectories are followed by using the computed force control method and a switching control method. The switching control method is combined with the computed force control method and genetic algorithm. In the switching control method, the genetic algorithm is only used for fine tuning in the compensation of the trajectory tracking errors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computed%20force%20method" title="computed force method">computed force method</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20manipulator" title=" hybrid manipulator"> hybrid manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=inverse%20kinematics%20of%20redundant%20manipulators" title=" inverse kinematics of redundant manipulators"> inverse kinematics of redundant manipulators</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20geometry%20truss" title=" variable geometry truss"> variable geometry truss</a> </p> <a href="https://publications.waset.org/abstracts/50402/trajectory-tracking-of-a-redundant-hybrid-manipulator-using-a-switching-control-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50402.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">347</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">19801</span> A Parallel Implementation of k-Means in MATLAB</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dimitris%20Varsamis">Dimitris Varsamis</a>, <a href="https://publications.waset.org/abstracts/search?q=Christos%20Talagkozis"> Christos Talagkozis</a>, <a href="https://publications.waset.org/abstracts/search?q=Alkiviadis%20Tsimpiris"> Alkiviadis Tsimpiris</a>, <a href="https://publications.waset.org/abstracts/search?q=Paris%20Mastorocostas"> Paris Mastorocostas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this work is the parallel implementation of k-means in MATLAB, in order to reduce the execution time.

Typically, the dimension of the linear equation is high and the matrix is sparse. A number of hybrid Bi-CG methods such as conjugate gradient squared (CGS), Bi-CG stabilized (Bi-CGSTAB), BiCGStab2, and BiCGstab(l) have been developed to improve the convergence of Bi-CG. Bi-CGSTAB has been most often used for efficiently solving the linear equation, but we have seen the convergence behavior with a long stagnation phase. In such cases, it is important to have Bi-CG coefficients that are as accurate as possible, and the stabilization strategy, which stabilizes the computation of the Bi-CG coefficients, has been proposed. It may avoid stagnation and lead to faster computation. Motivated by a large number of processors in present petascale high-performance computing hardware, the scalability of Krylov subspace methods on parallel computers has recently become increasingly prominent. The main bottleneck for efficient parallelization is the inner products which require a global reduction. The resulting global synchronization phases cause communication overhead on parallel computers. The parallel variants of Krylov subspace methods reducing the number of global communication phases and hiding the communication latency have been proposed. However, the numerical stability, specifically, the convergence speed of the parallel variants of Bi-CGSTAB may become worse than that of the standard Bi-CGSTAB. In this paper, therefore, we compare the convergence speed between the standard Bi-CGSTAB and the parallel variants by numerical experiments and show that the convergence speed of the standard Bi-CGSTAB is faster than the parallel variants. Moreover, we propose the stabilization strategy for the parallel variants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bi-conjugate%20gradient%20stabilized%20method" title="bi-conjugate gradient stabilized method">bi-conjugate gradient stabilized method</a>, <a href="https://publications.waset.org/abstracts/search?q=convergence%20speed" title=" convergence speed"> convergence speed</a>, <a href="https://publications.waset.org/abstracts/search?q=Krylov%20subspace%20methods" title=" Krylov subspace methods"> Krylov subspace methods</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20equations" title=" linear equations"> linear equations</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20variant" title=" parallel variant"> parallel variant</a> </p> <a href="https://publications.waset.org/abstracts/96373/numerical-studies-for-standard-bi-conjugate-gradient-stabilized-method-and-the-parallel-variants-for-solving-linear-equations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96373.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">19798</span> A TFETI Domain Decompositon Solver for von Mises Elastoplasticity Model with Combination of Linear Isotropic-Kinematic Hardening</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Cermak">Martin Cermak</a>, <a href="https://publications.waset.org/abstracts/search?q=Stanislav%20Sysala"> Stanislav Sysala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper we present the efficient parallel implementation of elastoplastic problems based on the TFETI (Total Finite Element Tearing and Interconnecting) domain decomposition method.

In our approach we consider an associated elastoplastic model with the von Mises plastic criterion and the combination of linear isotropic-kinematic hardening law.

Taking Classification and Regression Tree (CART) parallelization as an example, this paper proposes a parallel data mining algorithm based on SSP-OGini-PCCP. Aiming at the problem of choosing the best CART segmentation point, this paper designs an S-SP model without data association; and in order to calculate the Gini index efficiently, a parallel OGini calculation method is designed. In addition, in order to improve the efficiency of the pruning algorithm, a synchronous PCCP pruning strategy is proposed in this paper. In this paper, the optimal segmentation calculation, Gini index calculation, and pruning algorithm are studied in depth. These are important components of parallel data mining. By constructing a distributed cluster simulation system based on SPARK, data mining methods based on SSP-OGini-PCCP are tested. Experimental results show that this method can increase the search efficiency of the best segmentation point by an average of 89%, increase the search efficiency of the Gini segmentation index by 3853%, and increase the pruning efficiency by 146% on average; and as the size of the data set increases, the performance of the algorithm remains stable, which meets the requirements of contemporary massive data processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification" title="classification">classification</a>, <a href="https://publications.waset.org/abstracts/search?q=Gini%20index" title=" Gini index"> Gini index</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20data%20mining" title=" parallel data mining"> parallel data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=pruning%20ahead" title=" pruning ahead"> pruning ahead</a> </p> <a href="https://publications.waset.org/abstracts/119505/an-improved-parallel-algorithm-of-decision-tree" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119505.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">123</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">19794</span> Study of Temperature Difference and Current Distribution in Parallel-Connected Cells at Low Temperature</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sara%20Kamalisiahroudi">Sara Kamalisiahroudi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun%20Huang"> Jun Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhe%20Li"> Zhe Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianbo%20Zhang"> Jianbo Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Two types of commercial cylindrical lithium ion batteries (Panasonic 3.4 Ah NCR-18650B and Samsung 2.9 Ah INR-18650), were investigated experimentally.

However, the conventional ATS mainly works in a serial mode, and lacks the ability of testing several equipments at the same time. That leads to low test efficiency and ATS redundancy. Especially for a large majority of equipment under test, the conventional ATS cannot meet the requirement of efficient testing. To reduce the support resource and increase test efficiency, we propose a method of design for the parallel test based on the embedded system in this paper. Firstly, we put forward the general framework of the parallel test system, and the system contains a central management system (CMS) and several distributed test subsystems (DTS). Then we give a detailed design of the system. For the hardware of the system, we use embedded architecture to design DTS. For the software of the system, we use test program set to improve the test adaption. By deploying the parallel test system, the time to test five devices is now equal to the time to test one device in the past. Compared with the conventional test system, the proposed test system reduces the size and improves testing efficiency. This is of great significance for equipment to be put into operation swiftly. Finally, we take an industrial control system as an example to verify the effectiveness of the proposed method. The result shows that the method is reasonable, and the efficiency is improved up to 500%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20test" title="parallel test">parallel test</a>, <a href="https://publications.waset.org/abstracts/search?q=embedded%20system" title=" embedded system"> embedded system</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20test%20system" title=" automatic test system"> automatic test system</a>, <a href="https://publications.waset.org/abstracts/search?q=automatic%20test%20system%20%28ATS%29" title=" automatic test system (ATS)"> automatic test system (ATS)</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20management%20system" title=" central management system"> central management system</a>, <a href="https://publications.waset.org/abstracts/search?q=central%20management%20system%20%28CMS%29" title=" central management system (CMS)"> central management system (CMS)</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20test%20subsystems" title=" distributed test subsystems"> distributed test subsystems</a>, <a href="https://publications.waset.org/abstracts/search?q=distributed%20test%20subsystems%20%28DTS%29" title=" distributed test subsystems (DTS)"> distributed test subsystems (DTS)</a> </p> <a href="https://publications.waset.org/abstracts/99560/a-study-on-design-for-parallel-test-based-on-embedded-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99560.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">305</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">19792</span> Improvement of Parallel Compressor Model in Dealing Outlet Unequal Pressure Distribution</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kewei%20Xu">Kewei Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jens%20Friedrich"> Jens Friedrich</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Dwinger"> Kevin Dwinger</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei%20Fan"> Wei Fan</a>, <a href="https://publications.waset.org/abstracts/search?q=Xijin%20Zhang"> Xijin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parallel Compressor Model (PCM) is a simplified approach to predict compressor performance with inlet distortions. In PCM calculation, it is assumed that the sub-compressors’ outlet static pressure is uniform and therefore simplifies PCM calculation procedure. However, if the compressor’s outlet duct is not long and straight, such assumption frequently induces error ranging from 10% to 15%. This paper provides a revised calculation method of PCM that can correct the error. The revised method employs energy equation, momentum equation and continuity equation to acquire needed parameters and replace the equal static pressure assumption. Based on the revised method, PCM is applied on two compression system with different blades types. The predictions of their performance in non-uniform inlet conditions are yielded through the revised calculation method and are employed to evaluate the method’s efficiency. Validating the results by experimental data, it is found that although little deviation occurs, calculated result agrees well with experiment data whose error ranges from 0.1% to 3%. Therefore, this proves the revised calculation method of PCM possesses great advantages in predicting the performance of the distorted compressor with limited exhaust duct. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=parallel%20compressor%20model%20%28pcm%29" title="parallel compressor model (pcm)">parallel compressor model (pcm)</a>, <a href="https://publications.waset.org/abstracts/search?q=revised%20calculation%20method" title=" revised calculation method"> revised calculation method</a>, <a href="https://publications.waset.org/abstracts/search?q=inlet%20distortion" title=" inlet distortion"> inlet distortion</a>, <a href="https://publications.waset.org/abstracts/search?q=outlet%20unequal%20pressure%20distribution" title=" outlet unequal pressure distribution"> outlet unequal pressure distribution</a> </p> <a href="https://publications.waset.org/abstracts/39155/improvement-of-parallel-compressor-model-in-dealing-outlet-unequal-pressure-distribution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39155.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">331</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">19791</span> The Vision Baed Parallel Robot Control</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sun%20Lim">Sun Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyun%20Jung"> Kyun Jung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we describe the control strategy of high speed parallel robot system with EtherCAT network.

Redocumentation of legacy systems is vital for automatically or semi-automatically creating documentation for software lacking sufficient records. It aims to enhance system understandability, maintainability, and knowledge transfer. However, existing redocumentation methods need improvement in data processing performance and document generation efficiency. This stems from the necessity to efficiently handle the extensive and complex code of legacy systems. This paper proposes a method for semi-automatic legacy system re-documentation using semantic parallel processing and ontology. Leveraging parallel processing and ontology addresses current challenges by distributing the workload and creating documentation with logically interconnected data. The paper outlines challenges in legacy system redocumentation and suggests a method of redocumentation using parallel processing and ontology for improved efficiency and effectiveness. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=legacy%20systems" title="legacy systems">legacy systems</a>, <a href="https://publications.waset.org/abstracts/search?q=redocumentation" title=" redocumentation"> redocumentation</a>, <a href="https://publications.waset.org/abstracts/search?q=big%20data%20analysis" title=" big data analysis"> big data analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20processing" title=" parallel processing"> parallel processing</a> </p> <a href="https://publications.waset.org/abstracts/185855/a-proposed-framework-for-software-redocumentation-using-distributed-data-processing-techniques-and-ontology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185855.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">46</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">19787</span> Parallel 2-Opt Local Search on GPU</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wen-Bao%20Qiao">Wen-Bao Qiao</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-Charles%20Cr%C3%A9put"> Jean-Charles Créput</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To accelerate the solution for large scale traveling salesman problems (TSP), a parallel 2-opt local search algorithm with simple implementation based on Graphics Processing Unit (GPU) is presented and tested in this paper.

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.

The control of this mechanism and similar mechanisms is one that has always been the intention of the scholars. On the other hand, modeling the behavior of the system is difficult due to the large number of its parameters, and it leads to complex equations that are difficult to solve and eventually difficult to control. In this paper, a six-linkage robot has been presented that could be used in different areas such as medical robots. Using these robots needs a robust control. In this paper, the system equations are first found, and then the system conversion function is written. A new controller has been designed for this robot which could be used in other parallel robots and could be very useful. Parallel robots are so important in robotics because of their stability, so methods for control of them are important and the robust controller, especially in parallel robots, makes a sense. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=3-RRS" title="3-RRS">3-RRS</a>, <a href="https://publications.waset.org/abstracts/search?q=6%20linkage" title=" 6 linkage"> 6 linkage</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20robot" title=" parallel robot"> parallel robot</a>, <a href="https://publications.waset.org/abstracts/search?q=control" title=" control"> control</a> </p> <a href="https://publications.waset.org/abstracts/100326/designing-a-robust-controller-for-a-6-linkage-robot" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100326.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">159</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">19783</span> Parallel Querying of Distributed Ontologies with Shared Vocabulary</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sharjeel%20Aslam">Sharjeel Aslam</a>, <a href="https://publications.waset.org/abstracts/search?q=Vassil%20Vassilev"> Vassil Vassilev</a>, <a href="https://publications.waset.org/abstracts/search?q=Karim%20Ouazzane"> Karim Ouazzane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ontologies and various semantic repositories became a convenient approach for implementing model-driven architectures of distributed systems on the Web.

In the formulation of the problem, the Boussinesq approximation is considered and cross Neumann boundary conditions are specified for heat and mass walls conditions. The numerical method is based on the control volume approach with the third order QUICK scheme. Full approximation storage (FAS) with full multigrid (FMG) method is used to solve the problem. For the explored large range of the controlling parameters, we clearly evidenced that the increase in the depth of the cavity i.e. the lateral aspect ratio has an important effect on the flow patterns. The 2D perfect parallel flows obtained for a small lateral aspect ratio are drastically destabilized by increasing the cavity lateral dimension. This yields a 3D fluid motion with a much more complicated flow pattern and the classically studied 2D parallel flows are impossible. <p class="card-text"><strong>Keywords:</strong> <a
