in recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. the hybrid system presented in this article produced power with sofc and stirling engine. the purpose is to analyze a 50 kw solid oxide fuel cell that could produce enough thermal energy for a 10 kw stirling engine working in the hybrid s...

In the past decade, because of wide applications of hybrid systems, many researchers have considered modeling and control of these systems. Since switching systems constitute an important class of hybrid systems, in this paper a method for optimal control of linear switching systems is described. The method is also applied on the two-tank system which is a much appropriate system to analyze dif...

Hybrid automata have been proposed as a language for modelling and analysing the interaction of digital and analogue dynamics in embedded computation systems. In this paper, hybrid automata are studied from a dynamical systems perspective. Extending earlier work on conditions for local existence and uniqueness of executions of hybrid automata, we characterise a class of hybrid automata whose ex...

in this paper, a hybrid solid oxide fuel cell (sofc) and micro gas turbine (mgt) power system is parametrically studied to evaluate the effect of different operating conditions. the sofc/mgt power system includes sofc reactor, combustion chamber, compressor and turbine units, and two heat exchangers. the effects of fuel utilization, temperature, and pressure are assessed on performance of the h...

102 AbstractThis paper describes a commercial farmland application in Nigeria. The objective was to demonstrate the technical, economic and institutional viability of renewable energy (Hybrid system) for commercial farmland as well as to allow local partners to gain experience with hybrid/renewable technology, resource assessment, system sitting and operation. A commercial farmland of 30Km (5km...

In this article, the state-of-the-art multi-wave and hybrid imaging techniques in the field of nondestructive evaluation and structural health monitoring were comprehensively reviewed. A new direction for assessment and health monitoring of various structures by capitalizing the advantages of those imaging methods was discussed. Although sharing similar system configurations, the imaging physic...

We deene Dynamic Hybrid Automata (DHA) which are used to model environments where a variable number of agents have to interact according to an evolving set of relationships. In this formalism the world consists of DHA instances that are dynamically created and deleted. Each DHA instance evolves by executing transitions as a result of external events or incoming messages. As part of the transiti...

Silicon (Si) based complementary metal-oxide semiconductor (CMOS) technology has been the driving force of the information-technology revolution. However, scaling of CMOS technology as per Moore's law has reached a serious bottleneck. Among the emerging technologies memristive devices can be promising for both memory as well as computing applications. Hybrid CMOS/memristor circuits with CMOL (C...
