We discuss the constraints of lepton mixing angles from lepton number violating processes such as neutrinoless double beta decay, μ-e conversion and K decay, K− → πμμ which are allowed only if neutrinos are Majorana particles. The rates of these processes are proportional to the averaged neutrino mass defined by 〈mν〉ab ≡ | ∑3 j=1 UajUbjmj | in the absence of right-handed weak coupling. Here a, ...

To retrieve query image or sub regions of image, visual techniques are used such as color, shape, texture etc. Relevance feedback is used many times to improve the result and to help the user to express their preference. New approach is proposed in this paper for image retrieval with the help of retrieval techniques likecolor histogram, Match points, Wavelet, using Eigen values. Images from var...

Recently a lot of research is projected towards facial recognition. Face is a focus of attention in social intercourse, it plays a viral role in identification his emotion and conveying the emotion. It has its impact widely surveillance applications. Numbers of facial recognition algorithms were available in the literature, new approaches are still needed to capture face appearance variations d...

Abstract. In this article we prove a local large deviation principle (LLDP) for the critical multitype Galton-Watson process from spectral potential point. We define the so-called a spectral potential UK( ·, π) for the Galton-Watson process, where π is the normalized eigen vector corresponding to the leading Perron-Frobenius eigen value 1l of the transition matrix A(·, ·) defined from K, the tr...

This paper introduces an efficient Eigen values based technique for online iris image compression and identification of a human including the case of identical twins. The iris image is extracted after removing the pupil, eye brow, skin and other noise disturbances from an actual image. The extracted iris image is divided into different blocks of size of 16×16. Now, Eigen values are calculated f...

Abstract It has been shown that seventh-order boundary value problem can be transformed into a system of integral equations, which can be solved by variational iteration technique. It is to be mentioned that, presently, the literature on the numerical solutions of seventh order boundary value problems and associated eigen value problems is not available. The approximate results of the equations...

The present paper is devoted to the determination of displacement, stresses and temperature from three dimensional anisotropic half spaces due to presence of heat source. The normal mode analysis technique has been used to the basic equations of motion and generalized heat conduction equation proposed by Green-Naghdi model-II [1]. The resulting equation are written in the form of a vector –matr...
