ENHANCEMENT OF STATIC & DYNAMIC RESPONSE OF THE THREE PHASE INDUCTION MOTOR UNDER THE EFFECT OF THE EXTERNAL DISTURBANCES AND NOISE BY USING HYBRID FUZZY-GENETIC CONTROLLER
Journal ArticleABSTRACT:- For electrical drives good dynamic performance is mandatory so as to respond to the changes in command speed and torques, so various speed control techniques are being used for real time applications. The speed of a Three Phase Induction Motor can be controlled using various controllers like PID Controller, Fuzzy Logic Controller, Genetic Algorithm (GA) controller and Hybrid FuzzyGenetic Controller. Fuzzy-Genetic Controller is recently getting increasing emphasis in process control applications. The paper describes application of Hybrid Fuzzy-Genetic Controller in an enhancement of Static & Dynamic Response of the Three Phase Induction Motor under the effect of the external disturbances and noise that uses the Fuzzy-GA Controller for enhancement of Static & Dynamic Response of the Three Phase Induction Motor under the effect of the external disturbances and noise is implemented in MATLAB/SIMULINK. The simulation study indicates the superiority Hybrid Fuzzy-Genetic Controller over the Genetic Algorithm and fuzzy logic controller separately. This control seems to have a lot of promise in the applications of power electronics. The speed of the Three Phases Induction Motor Drives can be adjusted to a great extent so as to provide easy control and high performance. There are several conventional and numeric types of controllers intended for controlling the Three Phase Induction Motor speed and executing various tasks: PID Controller, Fuzzy Logic Controller; or the combination between them: Fuzzy-Swarm, Fuzzy-Neural Networks,
Fuzzy-Genetic Algorithm, Fuzzy-Ants Colony. We describe in this paper the use of Hybrid FuzzyGenetic Controller for enhancement of Static & Dynamic Response of the Three Phases Induction Motor Drives under the effect of the external disturbances. In this case, the obtained results were simulated on Simulink of Matlab.

New insights into mechanisms of opioid inhibitory effects on capsaicin-induced TRPV1 activity during painful diabetic neuropathy
Journal ArticleAbstract
Painful diabetic neuropathy is a disease of the peripheral sensory neuron with impaired opioid responsiveness. Since μ-opioid receptor (MOR) activation can inhibit the transient receptor potential vanilloid 1 (TRPV1) activity in peripherally sensory neurons, this study investigated the mechanisms of impaired opioid inhibitory effects on capsaicin-induced TRPV1 activity in painful diabetic neuropathy. Intravenous injection of streptozotocin (STZ, 45 mg/kg) in Wistar rats led to a degeneration of insulin producing pancreatic β-cells, elevated blood glucose, and mechanical hypersensitivity (allodynia). In these animals, local morphine's inhibitory effects on capsaicin-induced nocifensive behavior as well as on capsaicin-induced TRPV1 current in dorsal root ganglion cells were significantly impaired. These changes were associated with a loss in MOR but not TRPV1 in peripheral sensory neurons. Intrathecal delivery of nerve growth factor in diabetic animals normalized sensory neuron MOR and subsequently rescued morphine's inhibitory effects on capsaicin-induced TRPV1 activity in vivo and in vitro. These findings identify a loss in functional MOR on sensory neurons as a contributing factor for the impaired opioid inhibitory effects on capsaicin-induced TRPV1 activity during advanced STZ-induced diabetes. Moreover, they support growing evidence of a distinct regulation of opioid responsiveness during various painful states of disease (e.g. arthritis, cancer, neuropathy) and may give novel therapeutic incentives.

Some properties on a class of harmonic univalent functions defined by differential operator
Conference paperUsing a generalized derivative operator, we introduce and study a new class of harmonic univalent functions. In the present paper, we investigate some results for functions f belong to this class which include the necessary and sufficient coefficient bounds. Growth bounds and a closure property are also obtained.

Applications of web produced by hot air assisted melt differential electrospinning method
Conference paperMelt electrospinning, a technique that has gained increasing attention since it easily can generate continuous ultrafine fibers directly from polymer melts without the use of any solvent. Therefore, it is considered as a safe, cost effective, and environmental friendly technique. However, with all those great advantages, the technique still suffers some drawbacks such as: large fiber diameter and low throughput. The hot air assisted melt differential electrospinning (MDES) is a new technique invented by our research team that can solve or eliminate those drawbacks. The most important features of our used apparatus are: Needleless nozzle that could generate multiple Taylor cones around the bottom edge of the nozzle, which can result in a high throughput. The stretching force acting on the jets can be further strengthened by an air current provided by an air pressure gun. Interference between the high voltage supply …

Journal ArticleThe aim of this paper is to introduce a new class of analytic functions in the unit disk, with negative coefficients, via a new generalized derivative operator. We prove coecient inequalities for the new class of functions and for a subclass of it, as well as distortion theorems for functions in this subclass and for their derivatives. We determine the extreme points of the newly introduced subclass.
