dimensional synthesis of a parallel robot may be the initial stage of its design process, which is usually carried out based on a required workspace. since optimization of the links lengths of the robot for the workspace is usually done, the workspace computation process must be run numerous times. hence, importance of the efficiency of the algorithm and the cpu time of the workspace computatio...

The development of Floating Solar Photovoltaic (FPV) systems is a sign promising future in the Renewable Energy field. Numerous solar modules and inverters are mounted on large-scale floating platforms. It important to design system so that inverter operates its optimum range most time. In order achieve this goal DC side, serial parallel connections used. As result, cabling PV array architectur...

This paper proposes an autonomous and economic droop control scheme for DC microgrid application. In this method, a cost-effective power sharing technique among various types of DG units is properly adopted. The droop settings are determined based on an algorithm to individually manage the power management without any complicated optimization methods commonly applied in the centralized control ...

To solve the two-workshop integrated scheduling problem with same device resources, existing algorithms pay attention to horizontal parallel processing of process tree and ignore tightness between vertical serial processes. A algorithm for production time-selective strategy Backtracking Strategy is proposed. The order each in needs be determined, which will completed by sequence sequencing stra...

Parallel web crawling is an important technique employed by large-scale search engines for content acquisition. A commonly used inter-processor coordination scheme in parallel crawling systems is the link exchange scheme, where discovered links are communicated between processors. This scheme can attain the coverage and quality level of a serial crawler while avoiding redundant crawling of page...

The Multilevel Load Balancing algorithm (MLB) is a parallel algorithm that determines the communication schedule that is necessary to balance a distributed discrete load function. The MLB algorithm focuses on structured grid computations and their load balancing requirements, which we feel are largely unsupported within the load balancing community. The interface to MLB is inherently simple; a ...

The solution of large systems of linear equations is typically achieved by iterative methods. The rate of convergence of these methods can be substantially improved by the use of preconditioners, which can be either applied in a black-box fashion to the linear system, or exploit properties specific to the underlying problem for maximum efficiency. However, with the shift towards multiand many-c...

In this paper, a novel sub-channel based uplink Orthogonal Frequency Domain Multiple Access (OFDMA) random access scheme is proposed. In the next generation Wireless Local Area Network (WLAN), OFDMA was adopted in order to enhance throughput performance. OFDMA can be used for both downlink and uplink. In order to utilize OFDMA for uplink, AP needs to schedule stations’ packet transmission. In o...

The paper presents a priority rule-based heuristic serial schedule (SS) algorithm for a deterministic scheduling problem where multiple jobs with arbitrary precedence constraints are processed on multiple unrelated parallel machines. The objective is to minimise makespan. The priority rule employs the arithmetic mean and deviation of the processing times to determine the prior job-machine pair....
