This paper aims to design an optimal distributed multi-agent controller for load frequency control and optimal power flow purposes. The controller parameters are optimized using Grey Wolf Optimization (GWO) algorithm. The designed optimal distributed controller is employed for load frequency control in the IEEE 30-bus test system with six generators. The controller of each generator is consider...

The well-studied task of learning a linear function with errors is a seemingly hard problem and the basis for several cryptographic schemes. Here we demonstrate additional applications that enjoy strong security properties and a high level of efficiency. Namely, we construct: 1. Public-key and symmetric-key cryptosystems that provide security for key-dependent messages and enjoy circular securi...

performance optimization of a single-effect lithium bromide water absorption refrigerationsystem is the subject of this paper. first, the thermodynamic model of the system wasderived based on thefirst and second law analysis of an absorption refrigeration cycle with libr-water as the working fluid pair.then, the effects of different design parameters such as the generator inlet hot water temper...

in this paper the effect of block shape vortex generators (vgs) on an air-water fin-tube heat exchanger has been studied experimentally using exergy analysis method. also the effect of these vgs on increasing heat transfer rate has been simulated numerically and the results show a good agreement with the experiments. in this research we used a wind tunnel to produce wind flow over heat exchange...

We consider an electricity generator making offers of energy into an electricity pool market over a horizon of several trading periods (typically a single trading day). The generator runs a set of generating units with given start-up costs, shut-down costs and operating ranges. At the start of each trading period the generator must submit to the pool system operator a new supply curve defining ...

In this paper, psuedo random binary sequences are generated from the “Chaos Based Key Stream Generator- using novel Permutation technique with two dimensional patterns and substitution Z4 mapping” investigation of auto correlation property for seuwnces is presented. Initially a chaotic function, considering Logistic map used to generate Pseudo Random Numbers (PRNs). Then these numbers converted...

A propagated potential produced in the Pacinian corpuscle in response to mechanical stimuli leaves a refractory state of 7 to 10 msec. duration. The refractory state is presumably produced at the first intracorpuscular node of Ranvier. The recovery of receptor excitability for producing an all-or-none response to mechanical stimulation follows the same time course as that of the electrically ex...

recently, transverse flux permanent magnet generators (tfpmgs) have been proposed as a possible generator in direct drive variable speed wind turbines due to their unique merits. generally, the quality of output power in these systems is lower than multi stage fixed speed systems, because of removing the gears, so it’s important to design these kinds of generators with low ripple and lowest har...

By constructing a circuit consisting of a diode, resistor, and inductor in series with sinusoidallydriven function generator, period doubling bifurcation and chaotic behavior were observed in this experiment. By using a fixed frequency close to the value of resonance frequency of the circuit and adjusting the voltage amplitude of the function generator, the circuit exhibited chaotic behavior. A...

In this paper we describe a theoretical model of chaos machine, which combines the benefits of hash function and pseudo-random function, forming flexible one-way push-pull interface. It presents the idea to create a universal tool (design pattern) with modular design and customizable parameters, that can be applied where randomness and sensitiveness is needed (random oracle), and where appropri...
