In pipeline transportation of slurry, the existing calculation models of critical deposition velocity face the problem of different model forms only suitable for specific conditions. To address this problem, this paper uses improved “shuffled frog leaping algorithm” (SFLA) to optimize the parameters of the computational model in order to calculate critical deposition velocity. This has been fou...

Several benefits can be gained from implementation of Distributed Energy Resources (DERs) in distributed systems. This paper proposes the application of Shuffled Frog Leaping Algorithm to optimally determination the location and size of multiple DERs considering a multi-objective benchmark. Several objectives including loss minimization, reduction in power purchased from the network and upgrade...

Service-oriented architecture provides the ability to combine several web services in order fulfil a user-specific requirement. In dynamic environments, appearance of unforeseen events can destabilize composite service (CWS) and affect its quality. To deal with these issues, must be dynamically reconfigured. Dynamic reconfiguration may enhanced by avoiding invocation degraded predicting QoS for...

In order to achieve the sensing, communication and processing tasks of Wireless Sensor Networks, an energy-efficient routing protocol is required to manage the dissipated energy of the network and to minimalize the traffic and the overhead during the data transmission stages. Clustering is the most common technique to balance energy consumption amongst all sensor nodes throughout the network. I...

In the context of carbon trading, energy conservation and emissions reduction are development directions integrated systems. order to meet requirements in power grid, considering different responses system time periods, a wind-hydrogen multi-time scale scheduling model was established optimize energy-consumption problem system. As is multiobjective nonlinear problem, artificial fish swarm algor...

Ocean exploration is one of the fundamental issues for sustainable development human society, which also basis realizing concept Internet Underwater Things (IoUT) applications, such as smart ocean city. The collaboration heterogeneous autonomous marine vehicles (AMVs) based on underwater wireless communication known a practical approach to exploration, typically with surface vehicle (ASV) and g...

This article is based on the application of heuristic algorithms to minimize the average power consumption in a VLSI circuit. The idea is to find the optimum layout and temperature for a 3 stage ring oscillator with minimal dynamic average power. The objective function is the same as average power (Pavg) of 3 stage ring oscillator with 6 CMOS inverters that depends on the temperature and the tw...

Multicast device-to-device (D2D) communication technology is considered as one of the new technologies in fifth generation (5G) networks that directly addresses need for content sharing among internet users. In fact, when direct available between devices, spectral efficiency improved by reusing licensed cellular spectrum. The current studies show D2D increases network capacity and reduces laten...

In recent years, various control methods have been proposed for maximum power point tracking (MPPT) of photovoltaic (PV) plants. Different MPPT PV systems in the literature evaluated terms energy efficiency, conversion, dynamic performance and reliability different environmental conditions. Among methods, Artificial Neural Network (ANN) is one best due to its ability noise rejection no need pri...
