In order to solve the recognition of polyphase code radar signal, this paper gives two methods based on Frank code, i.e. the high-order spectrum recognition method and the fractional Fourier transform (FRFT) method, by analyzing the micro characteristics of polyphase code signals in time and frequency domain respectively. And a recognition algorithm based on Wigner-Hough transform (WHT) is deve...

So far many methods of recognizing the face arose, each has the merits and demerits. Among these methods are methods based on Hidden Markov models, and their advantage is the high efficiency. However, the traditional HMM uses onedimensional data, which is not a good solution for image processing, because the images are two-dimensional. Transforming the image in a one-dimensional feature vector,...

Reactive power management has been a vital downside for the last a few years. The role of reactive power will be understood because it affects voltage stability, power issue and losses during a grid. To unravel this downside several approaches are utilized in the literature. Capacitors are used for identical. However the matter lies to find the best location and size of the capacitors. This pap...

Scalability in VANET environment is an important issue of concern in recent years. Many approaches have been presented in the recent years and compared their merits and demerits with the existing approaches. In the present work a hybrid technique extension to the GPSR protocol is presented which is based on the content based filtering approach and the clustering approach. The filtering approach...

This article provides an overview of solution-based methods for the controllable synthesis of metal oxides and their applications for electrochemical energy storage. Typical solution synthesis strategies are summarized and the detailed chemical reactions are elaborated for several common nanostructured transition metal oxides and their composites. The merits and demerits of these synthesis meth...

The human face is a very important feature as it contains vital elements like the eyes, nose, lips, and eyelids. Numerous factors can damage soft tissue in the face causing functional and cosmetic defects. One of the common causes of disfiguring facial scars is burns. There are different methods of reconstruction each with their own merits and demerits. Herein, we describe a method for the faci...

We deal with DNA combinatorial code constructions, as found in the literature, taking the point of view of possibilistic information theory and possibilistic coding theory. The possibilistic framework allows one to tackle an intriguing information-theoretic question: what is channel noise in molecular computation? We examine in detail two representative DNA string distances used for DNA code co...

In this chapter we have discussed the research work done on the basis of literature review and study. The research methodology and the techniques to modify the present designs in order to achieve better performance have been discussed with their merits and demerits. In this paper FS-SERF and HSSERF full adder topologies are presented. The analysis of Power, Delay, Power Delay Product (PDP) opti...

The term ‘power quality’ [1-2] refers to the purity of the voltage and current wave-form, and a power quality disturbance is a deviation from the pure sinusoidal form. Harmonics superimposed on the fundamental are one cause of such deviations. Power quality problems [1-2] like voltage harmonics, voltage flickers, voltage sags and voltage swells, current harmonics, current unbalance, reactive cu...

Mobile Ad-hoc Network (MANET) is a transitory and infrastructureless network supported by no fixed trusted infrastructure. To achieve security goals like: authentication, integrity, non-repudiation, privacy, a secret key (or session key) is necessary to be shared between the sender and receiver. Because of the nature of MANET, it is unrealistic in many circumstances to implement Certification A...
