A pilot scale study was conducted to find out the different forms of metals if fly ash (FA) and bioaccumulation of these metals in the naturally growing vegetation on FA dumps. The total, acid extractable, bioavailable and water soluble fraction of metals of Fe, Cu, Mn, Zn, Ni, Co and Pb, and their bioaccumulation coefficients (BAC) on naturally growing(More)
The color space conversion employs a significant function in preprocessing phase of digital image processing. Color conversion can improve the quality of images. The color space conversion is used in various applications such as commercial, multimedia, computer vision, visual tracking systems etc. The objective is to convert one color space to another and(More)
— The design of low power circuit has begun to be a prime concern in chip design, substantially for portable and high performance systems. Power reduction is one of the mandatory issues. Scaling the transistor size causes sub-threshold leakage currents to become a massive component of total power dissipation. Therefore, effective techniques are required to(More)
Recently, there has been a rapid growth in the wireless communication technique. Mobile sinks can be mounted upon urban vehicles with fixed trajectories provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches uses either single-hop transfer of data from SNs that lie within the MS's range or(More)
Modern DSP systems are often well suited to VLSI implementation. Indeed, they are often technically feasible or economically viable only if implemented using VLSI technologies.. The paper is focused on the design of an efficient VLSI architecture for FIR filters which aims at reducing the power consumption and also to reduce the hardware complexity. In the(More)
OFDM/OQAM is preferred as multicarrier system which operates over a multipath channel. By using the multipath channel the signal-to-noise ratio. In earlier, sub carriers are used to transmit the signals. Nowadays, FFT and DFT are used for transmitting the signals based upon the bit values. AWGN is a channel used to identify the noise produced at the output(More)
The Core Stateless Fair Queuing (CSFQ) is a distributed approach of Fair Queuing (FQ). The limitations include its inability to estimate fairness during large traffic flows, which are short and bursty (VoIP or video), and also it utilizes the single FIFO queue at the core router. For improving the fairness and efficiency, we propose an Enhanced Core(More)
