To study the effects of and interactions among feed types, seasons, and agroecological zones on the total fungal viable count and aflatoxins B1 (AFB1), B2 (AFB2), G1 (AFG1), and G2 (AFG2) production in poultry feed, an experiment was conducted using three-factorial design. A total of 216 samples of poultry feed ingredients, viz. maize, wheat, rice, cotton(More)
— Resolution and contrast are the two important attributes of an image. In this paper we developed a method to enhance the quality of the given image. The enhancement is done both with respect to resolution and contrast. The proposed technique uses DWT and SVD. To increase the resolution, the proposed method uses DWT and SWT. These transforms decompose the(More)
—Phase unwrapping (PU) is the process of recovering the absolute phase ϕ from the wrapped phase ψ and it is key problem in interferometry SAR processing (In-SAR) and Sonar (In-SAS), MRI (medical imaging) & signal processing applications, etc. In all these applications the observation mechanism is an absolute phase (2π-periodic function of the true phase).(More)
A different kind of approach was employed in designing a multi-band antenna by using chebyshev distribution to fulfill broadband and military applications on FR4 substrate. The presented approach is based on combining a rectangular and a equilateral triangular patch with proper slots placed on each part and is simulated using concerto software. By changing(More)
Detection, parameter extraction and the tracking of moving high speed small targets are challenging tasks for the radar system design and in most of radar applications, target's range migration was one of the reasons that limits integration time and consequently reduces the processing gain. The high speed makes the target shift through range cells during(More)
India is planned to develop a satellite based navigation systems known as Indian Regional Navigational Satellite System (IRNSS) for positioning applications. Design of IRNSS antenna at user segment is necessary. In order to design antenna, a new planar, wideband feed for a slot spiral antenna is designed using HFSS software simulations. This paper describes(More)

The aim of this paper is to print characters by providing the interfaces to connect a VGA port for graphical output and a PS/2 port for keyboard input. This system is then to be synthesized on an FPGA board, and should be capable of running a program to display characters that takes input from the keyboard and prints the results to a VGA monitor. This paper(More)
Multi antenna orthogonal frequency division multiple access (MU-OFDMA) is one of the most promising technique for high downlink capacity in the next generation wireless systems like 3G,4G,LTE..etc. In multi cell networks , Resource allocation is distributed within each base station so in such a scenario Margin adaptive (MA) problem plays an important role ,(More)
