Software is a critical issue nowadays. The selection and design suitable technique/process/method for maintenance phase for the same, we required suitable reengineering tool and technique, extractor one of the most important component of reengineering tool, for design appropriate extractor, we survey the several extractors, which read the source code find out the architecture of code and design level problems and remove the problems make a new update architecture diagram. We studied several extractors and not found any suitable tool for achieve completeness architecture recovery. In this paper, we tried to survey available extractor to find their merits and demerits. The requirement set is proposed for the constructing the new extractor those who take the merits of existing extractor and some required based on our study. © Springer India 2014. Source

In order to suppress the Multiple-Access Interference (MAI) in the DS CDMA system, a new RAKE receiver based on parallel interference elimination is proposed in this paper. The multiple-access interference is evaluated by known user information and tentative decision. Then the performance over Rayleigh fading channel are analyzed and compared to convention PIC receiver and PIC RAKE receiver. It is shown that RAKE receiver performance can be improved greatly by using Parallel Interference Cancellation (PIC) method with simple structure and easy implementation [1]. © 2013 IEEE. Source

This paper describes a methodology for reliability assessment of electrical distribution system accounting random repair time omission for each section. A distributor segment in a distribution system has failure rate and repair time which decide mean up time (MUT) and mean down time (MDT) at load points. Usually the reliability analysis is based on exponential failure and repair laws. The repair time is a random variable. Certain values of repair times are smaller which may be neglected based on the tolerance time of consumers at each load point. Complete reliability analysis with repair time omission has been presented. Modified mean up time, mean down time and unavailability (h/year) have been obtained at each load point using state transition sampling technique. These have been obtained accounting outage due to random repair time omission. The methodology has been implemented on two distribution systems. © 2012 Elsevier Ltd. All rights reserved. Source

The Fractional Fourier transform (FrFT), as a generalization of the classical Fourier transform, was introduced many years ago in mathematics literature. For the enhanced computation of fractional Fourier transform, discrete version of FrFT came into existence i.e. DFrFT. This paper illustrates the advantage of discrete fractional Fourier transform (DFrFT) as compared to other transforms for steganography in image processing. The simulation result shows same PSNR in both domain (time and frequency) but DFrFT gives an advantage of additional stego key i.e. order parameter of this transform. © 2013 IEEE. Source

Average interruption duration, interruption duration per year and failure rate at a load point are the basic reliability indices required to be evaluated. These indices depend on failure rate and average repair time of each feeder. Usually in reliability assessment of distribution system failure and repair rates are assumed constant. Further it has been observed that random outage time may be neglected at load point. This has been an important issue in determining the modified reliability indices accounting random outage time. Hence this paper presents a methodology to determine basic reliability indices subject to neglecting of certain repair time which is truly a random variable. The methodology is based on smooth boot strapping technique along with Monte Carlo simulation (MCS). The developed algorithm has been implemented on two sample test systems. The results obtained has been compared those with MCS and obtained with general boot strapping. © 2013 Elsevier Ltd. All rights reserved. Source
