The present paper describes the phase only pattern synthesis for the active phased array antenna using genetic algorithm. The phase only synthesis is required to broaden and shape the beam in transmit mode of operation where all elements are fed through the saturated power of transmit/receive modules (TRM). This technique is very useful in multifunctional radar application where broadened beam ...

This paper presents the simulation of auto-thermal ammonia synthesis reactor. Our target here is to estimate the optimal reactor length which will give the maximum profit from the ammonia reactor. There are many literatures which are interested in ammonia simulation in the past but all need some corrections due to either uncorrected model used or uncorrected algorithm. We used here the ODE45 so...

An improved method based on a genetic algorithm (GA) is developed to design a broadband electrical impedance matching network for piezoelectric ultrasound transducer. A key feature of the new method is that it can optimize both the topology of the matching network and perform optimization on the components. The main idea of this method is to find the optimal matching network in a set of candida...

Power system throughout the world is undergoing tremendous changes and developments due to rapid Restructuring, Deregulation and Open-access policies. Greater liberalization, larger market and increasing dependency on the electricity lead to the system operators to work on limited spinning reserve and to operate on vicinities to maximize the economy compromising on the reliability and security ...

In this paper proposes a fuzzy multi-objective hybrid Genetic and Bee colony optimization algorithm(GA-BCO) to find the optimal restoration of loads of power distribution network under fault.Restoration of distribution systems is a complex combinatorial optimization problem that should beefficiently restored in reasonable time. To improve the efficiency of restoration and facilitate theactivity...

long-term settlement of msw landfills is a complex process, which is explained by the following two mechanisms: (1) the mechanical long-term compression of degradable organic solids (dos) and un-degradable organic solids (udos); and (2) the decomposition-based compression of the dos. based on these two distinct settlement mechanisms, in this study, the authors propose a new estimation model to ...
