The need of reducing CO2 emissions in electricity generation field for solving global warming problems have led to increase the interest in Micro-Grid (MG) especially the one which included renewable sources. MG normally operates in normal interconnected mode and connects with the main grid. When a large disturbance happens in main grid, MG transfer to islanding mode. This paper deals with conn...

In this paper, a hybrid combination of Neuro and Fuzzy is proposed as a controller to solve the Automatic Generation Control (AGC) problem in a restructured power system that operates under deregulation pedestal on the bilateral policy. In each control area, the effects of the possible contracts are treated as a set of new input signal in a modified traditional dynamical model. The prominent ad...

AIM to assess the incidence of HPV -DNA in women with ASC/AGC compared to patients with normal Pap smears. MATERIAL AND METHODS The study group consisted of 242 women (207 ASC and 35 AGC cases). The control group counted 200 age-matched women with negative Pap smears. Cervical samples collected from all the participants were tested for the presence of HPV-DNA using the Hybrid Capture-2 test. ...

Signaling and trafficking over membranes involves a plethora of transmembrane proteins that control the flow of compounds or relay specific signaling events. Next to external cues, internal stimuli can modify the activity or abundance of these proteins at the plasma membrane (PM). One such regulatory mechanism is protein phosphorylation by membrane-associated kinases, several of which are AGC k...

Spectrum sensing is key to many applications like dynamic spectrum access (DSA) systems or telecom regulators who need to measure utilization of frequency bands. The International Telecommunication Union (ITU) recommends a 10 dB threshold above the noise to decide whether a channel is occupied or not. However, radio frequency (RF) receiver front-ends are non-ideal. This means that the obtained ...

David V. Anderson, Richard W. Harris, and Douglas M. Chabries Brigham Young University, Provo, Utah ABSTRACT A new hearing compensation algorithm based on a homomorphic multiplicative AGC (automatic gain control) is evaluated and compared against commercially available digitally programmable analog hearing aids. Both quantitative (speech recognition and threshold) and qualitative tests were use...

The aim of this article is to provide a complete analysis of the behavior of a noncontact atomic force microscope ~NC-AFM!. We start with a review of the equations of motion of a tip interacting with a surface in which the stability conditions are first revisited for tapping mode. Adding the equations of automatic gain control ~AGC!, which insures constant amplitude of the oscillations in the N...

OBJECTIVES The purpose of this study was to improve bimodal benefit in listeners using a cochlear implant (CI) and a hearing aid (HA) in contralateral ears, by matching the time constants and the number of compression channels of the automatic gain control (AGC) of the HA to the CI. Equivalent AGC was hypothesized to support a balanced loudness for dynamically changing signals like speech and i...

This paper describes an objective speech quality assessment method developed for the Hungarian NMT450 mobile telephone system. The method is based on a psychoacoustic front end followed by a cognitive modeling component. Special problems of the NMT system, such as hand-overs, the effects of automatic gain control (AGC) and intrusion of signaling noise are addressed in the cognitive module. Corr...
