background: technetium-99m radioisotope is the backbone of any nuclear medicine institute. this radioisotope is acquired by the elution of molybdenum-99/technetium-99m generator which emits 141 kev gamma ray and having 6.04 hour half-life. occasionally the contents of molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. this...

In this Paper Analysis of Calculation Methods to calculate the losses and output power of wind turbine generator systems with using two types first one is Squirrel-Cage Induction Generator and the second is Doubly-fed Induction Generator. By using the existing methods in this paper, we can evaluate the generated output power, total system losses, total energy generated, efficiency and capacity ...

1  Abstract-This paper was written by a Working Group of the IEEE Power System Relay Committee to provide guidance to the industry to better coordinate generator protection with generator control. The paper discusses specific calculation methods that can be used to insure generator protection and excitation system control are fully coordinated. It also specifically addresses the coordination o...

I describe the optimizing matrix element generator O’Mega [1, 2] and Wolfgang Kilian’s event generator generator WHIZARD [3]. These tools cooperate in the automated production of efficient unweighted event generators for linear collider physics.

In this short paper we propose a pseudorandom number generator over EC based on Pollardlike method. In contrast to the well known Elliptic Curve Random Number Generator (see e.g. ANSI and NIST draft standards) the generator is based on a random walk over the group of EC-points like in the original Pollard’s rho algorithm and only resembles a little bit the linear congruential generator over ell...

Response patterns resulting from repetitive mechanical stimulation of the corpuscle depend on (1) the time course of recovery of the generator potential, on (2) the recovery of critical firing height, and on (3) the stimulus strength/generator potential function. By either augmenting stimulus frequency at constant strength, or by reducing strength at constant frequency, a sequence of propagated...

Since Advanced Encryption Standard (AES) in stream modes, such as counter (CTR), output feedback (OFB) and cipher feedback (CFB), can meet most industrial requirements, the range of applications for dedicated stream ciphers is decreasing. There are many attack results using algebraic properties and side channel information against stream ciphers for hardware applications. Al-Hinai et al. presen...

This paper is concerned with behavior analysis and improvement of wind turbines with Doubly Fed Induction Generator (DFIG) when using a new fractional-order control strategy during wind variations. A doubly fed induction generator, two types of variable frequency power electronic converters and two input wind waveforms are considered. A fractional-order control strategy is proposed for the wind...

Accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. In this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...
