This paper describes the unit commitment (UC) problem, which aims for the minimization of wind-thermal operating cost and emission cost of thermal units by considering thermal valve point effect and uncertainty of wind power. The uncertainty of wind power is incorporated with the help of Weibull probability density function (PDF), which is used to evaluate the underestimation and overestimation costs...
In this work, the microstrip low pass filter has been designed with acut-off frequency 8GHz. In this, wide stopband and high attenuation have been developed which is composed of multiple open stubs and CSRR technique. With proper selection of the electrical lengths and CSRR parameters wide stop band can be generated. A detailed design procedure has been provided. A comparative study has also been...
In this paper a broadband Rectangular micro strip Antenna with parasitic patches on CPW feed is presented. Antenna composed of a planar rectangular patch element with two parasitic patches for broad banding. The overall size of the antenna is 62 mm X 47 mm X 1.6 mm including the finite ground CPW feeding mechanism and total volume of the antenna is 4.66 cm3. The antenna operates across frequency bands...
In this paper a broadband monopole antenna with half u slot cut in rectangular patch on coplanar wave guide (CPW) feed is presented. The antenna composed of a planar rectangular patch element embedded with half U slot cut with good impedance matching. The parametric study is performed to understand the characteristics of the proposed antenna. The overall size of the antenna is 62 mm X 47 mm X 1.6...
Wide band truncated rectangular micro strip antenna with slot loaded stacked patches and defected ground plane structure is presented in this paper to increase the bandwidth. By inserting slot in the ground plane the bandwidth of the stacked truncated rectangular micro strip antenna is improve by twice. The bandwidth before adding the slot in the ground structure was 29.7% whereas after adding the...
In this paper, a novel design of coplanar micro strip patch antenna is presented for ultra wideband (UWB) and smart grid applications. It is designed on a dielectric substrate and fed by a coplanar wave guide (CPW). Micro strip patch antenna consists of a circular patch with an elliptical shaped eye opening in the center to provide multiband operations. The antenna has wide bandwidth of 5 GHz between...
RASSF5 is a member of the Ras association domain family, which is known to be involved in cell growth regulation. Expression of RASSF5 is extinguished selectively by epigenetic mechanism(s) in different cancers and cell lines, and reexpression usually suppresses cell proliferation and tumorigenicity. To date, the mechanism regulating RASSF5 nuclear transport and its role in cell growth regulation...
In this paper present a modified method of measurement for E-Plane branch line waveguide type directional coupler. Basically here we measure the directional coupler electrical parameters of 3 dB and 6 dB for different frequency bands.
Design of Rotman type beam forming bootlace lens have been discussed. Scattering matrix of the bootlace lens has been evaluated using the contour integral approach. Radiation characteristics of the bootlace lens have been investigated with different types of the microstrip antenna.
Design and analysis of a microstrip low pass filter with open circuited stubs has been described in this paper. To improve the frequency response fractals in the conventional geometry have been proposed.
Design and analysis of a stepped impedance elliptical microstrip low pass filter has been described in this paper. To improve the frequency response, fractals have been proposed in the conventional design. Simulated and measured results of the conventional as well as the fractal filter have been analyzed.
Design of a stepped impedance microstrip low pass filter is proposed here, with improved performances. The result of the filter shows accurate attenuation at the cut-off frequency.
This paper outlines a multiband antenna design based on fractal concepts. Simulation studies to investigate the influence of fractals on resonant frequencies are presented. The numbers of fractals are varied and influence on frequency bands is observed
