The distribution function of the electrons produced in the interaction between an intense electromagnetic wave and a neutral gas is derived and is shown to be nonequilibrium and anisotropic. By assuming that the time scale of gas ionization is much greater than the field period, it is shown that the electron distribution function formed in microwave and optical discharges has sharp anisotropy a...

Network reconfiguration is a nonlinear optimization procedure which calculates a radial structure to optimize the power losses and improve the network reliability index while meeting practical constraints. In this paper, a multi-objective framework is proposed for optimal network reconfiguration with the objective functions of minimization of power losses and improvement of reliability index. T...

Nowadays, presence of photovoltaic systems in distribution network is not without challenge and it may not have economic productivity for the system under the lack of optimal management. Energy storage systems are able to cope with this problem. Therefore, in this paper, a new method is proposed for energy management of the distribution networks in order to show that how presence of the energy ...

Resilience is defined as the system ability to keep an acceptable performance level against a sever disturbance and to return to a stable condition in a suitable time. Occurrence of inconvenient weather conditions and natural disasters, which are growing in number and severity during the last years, has always led to damages and wide outage throughout the distribution network. Therefore the ass...

The temperature of a gas corresponds to the average kinetic energy of the molecules in the gas. What can we say about the distribution of velocities in the gas at a given temperature? We know from physics that this distribution is the maximum entropy distribution under the temperature constraint, otherwise known as the Maxwell-Boltzmann distribution. The maximum entropy distribution corresponds...

supply security of energy is one of the main challenges of industrialized countries in recent decades. also, it has been noted that in recent years other countries like new emergence asian countries and latin american countries, have understood the role and importance of energy. however, oil and gas have more importance for numerous reasons such as convenience availability, high thermal value a...

Pipe systems are in the cores of many real life applications including water, oil and gas distribution as well as airconditioning and compressed air management. Modeling and analysis of flow in pipe networks is of great practical significance in all these areas. Pipe networks are usually made up of thousands of components such as pipes, pumps, valves, tanks and reservoirs. One common way to mod...

A novel intelligent neural optimizer with two objective functions is designed for electrical distribution systems. The presented method is faster than alternative optimization methods and is comparable with the most powerful and precise ones. This optimizer is much smaller than similar neural systems. In this work, two intelligent estimators are designed, a load flow program is coded, and a spe...
