This paper presents a method of estimating target location and scattered waveforms, whose accuracies are interdependent. The technique relies on iterative improvements of estimated dominant-frequency waveforms. Description of the algorithm is followed by statistical simulation examples. The performance of the technique is contrasted with conventional methods and statistical bounds in terms of t...

In this article we construct closed, isospectral, non-isometric locally symmetric manifolds. We have three main results. First, we construct arbitrarily large sets of closed, isospectral, non-isometric manifolds. Second, we show the growth of size these sets of isospectral manifolds as a function of volume is super-polynomial. Finally, we construct pairs of infinite towers of finite covers of a...

The principle of image enhancement is to improve the interpretability of information contained in the image for human perception or to provide a more suitable input for automated image processing systems. Many images like medical images, satellite images, aerial images and natural images suffer from contrast and noise issues. It is necessary to enhance the contrast and remove the noise to incre...

The recently introduced Complex Spectral Phase Evolution (CSPE) algorithm is a super-resolution technique for the estimation of the exact frequency values of sinusoidal components in a signal. However, if a component of the signal does not exist within the entire data set, it cannot be identified out by CSPE algorithm, even though it still may be visible in the FFT magnitude spectrum. In this p...

This paper proposes an emotion recognition system. Human emotion can be expressed through many kinds of medium such as speech, image, facial expression, and so forth. This paper focuses on the textual data of them. Proposed system is a hybrid system that uses alternatively two methods, keyword-based and machine learning method. Keyword-based methods are traditional approaches using emotional ke...

Infrared Functional Imaging was applied to the study of Raynaud’s Phenomenon obtaing a simultaneous assessment of the thermal properties of all five fingers of both hands of a group of patients with respect of a control group. The method is based on the use of high-resolution telethermography imaging and allows identification of objective parameters from the re-warming curves of finger immediat...

Abstract: Till today, Web portal Model is popular e- business model which selling a wide range of products, with both depth and breadth range. However, over recent years, consumers have become more discerning due to changing lifestyles, spending priorities shopping patterns (Fisher, 1998). The focus this research paper draw attention marketers shoppers towards the need develop hypothetical name...
