Usage of fuzzy differential equations (FDEs) is a natural way to model dynamical systems under possibilistic uncertainty. We consider second order hybrid fuzzy differentia

introduction saline wastewaters contain mineral salts which are often produced by industries such as seafood processing, cannery, vegetables, and tanning. they are imported into the sewage collection network. in coastal cities, saline water consumption seems indifferent in household parts and highlevels ofground water, leaksaltwater, precipitation duringdifferentseasons,and sea level are the ot...

Supervisory control and fault diagnosis of hybrid systems need to have complete information about the discrete states transitions of the underling system. From this point of view, the hybrid system should be abstracted to a Discrete Trace Transition System (DTTS) and represented by a discrete mode transition graph. In this paper an effective method is proposed for generating discrete mode trans...

Increasing of net energy storage (Q net) and discharge time of phase change material (t PCM), simultaneously, are important purpose in the design of solar systems. In the present paper, Multi-Objective (MO) based on hybrid of Particle Swarm Optimization (PSO) and multiple crossover and mutation operator is used for Pareto based optimization of solar systems. The conflicting objectives are Q net...

The power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. This paper presents modeling and optimization of a photovoltaic (PV)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in Rafsanjan, Iran. For this location, different hybrid systems are studied and ...

This paper presents easily verifiable sufficient conditions for the existence of Zeno behavior in Lagrangian hybrid systems, i.e., hybrid systems modeling mechanical systems undergoing impacts.

short term prediction of traffic flow is one of the most essential elements of all proactive traffic control systems. although various methodologies have been applied to forecast traffic parameters, several researchers have showed that compared with the individual methods, hybrid methods provide more accurate results . these results made the hybrid tools and approaches a more common method for ...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...
