With the increasing popularity of battery-driven portable electronics, there is a growing demand for low-power circuit designs. In a typical CMOS digital circuit, power dissipation can be categorized into the dynamic power dissipation, leakage power dissipation, and short-circuit power dissipation. While dynamic power dissipation remains to be the most(More)
Energy Efficiency is important role of the Wireless Sensor Networks Researchers. The Energy Efficiency is one of the roles where the data is transmitted to the base station. Energy Techniques is used to improve the reliability of a link. When the data is transmitted communicates to the nodes at exact power to the clustering technique algorithm using graph(More)
The load-frequency control (LFC) is used to restore the balance between load and generation in each control area by means of speed control. The objective of LFC is to minimize the transient deviations and steady state error to zero in advance. This paper investigates LFC with time delays using proportional integral (PI) Controller and fuzzy logic controller(More)
The high-voltage gain converter is widely employed in many industry applications, such as photovoltaic systems, fuel cell systems, electric vehicles, and high-intensity discharge lamps. This paper a novel single-switch high step-up non isolated dc–dc converter integrating coupled inductor with extended voltage doubler cell and diode–capacitor techniques.(More)
Background: A dye is used to impart colour to a material, mainly azo dyes are the major produced synthetic dyestuffs because they are extensively used in the textile, leather, pharmaceutical and cosmetics industries. Objective: The azo dyes are important chemical pollutants released from textile industries as unwanted effluents, so to evaluate the(More)
OFDM Signal combines the multiple symbol representations method with a signal clipping method using a new hybrid PAPR reduction technique. The amplitude of the signal is limited to the threshold value using clipping method which considering the signal must be interpolated before A/D conversion and also different filtering technique has been proposed. The(More)
The operating performance of the Grid Connected Inverters (GCIs) in windmill is highly important related to stable and safety operation of a “Smart Grid” (SG). These inverters control features not only cover the renewable energy conversion and active power feeding into the utility grid but also they cover the grid voltage stabilization, supporting with(More)
While we capture images we used to get the noise to remove the noise we are using so many techniques which were not at reached the user requirement finally we came up through three paradigms which can fulfil user requirements: 1) the deterministic filter; 2) Bayesian estimation; and 3) the conjunctive deploring algorithm (CODA), which performs the(More)
In our work describes a method for accurately tracking persons in indoor surveillance video stream obtained from a static camera with difficult scene properties including illumination changes and solves the major occlusion problem by using Kalman filtering. First, moving objects are precisely extracted by determining its motion, for further processing. The(More)
The load–frequency control (LFC) problem has been one of the major subjects in a power system. In practice, LFC systems use proportional–integral (PI) controllers. However since these controllers are designed using a linear model, the non-linearities of the system are not accounted for and they are incapable of gaining good dynamical performance for a wide(More)
