This paper deals with the study of interest in the fields of Steganography and Steganalysis. Steganography involves hiding information in a cover media to obtain the stego media in such a way that the cover media is perceived not to have any embedded message for its unintended recipients. Steganalysis is the mechanism of detecting the presence of hidden information in the stego media and it can...

Abstract In this paper, we focus on the penalty finite element method for non stationary porous media model. We begin by showing existence and uniqueness of solution initial problem. Error estimates velocity pressure are obtained via energy method. introduce a time discretization use backward Euler scheme combined with fully discrete to approximate penalized problem establish an error estimate ...

This paper presents TRIM+, an architecture for transparent mobility management with route optimization in IMS based networks. The design of our architecture is based on a previous work referred to as TRIM. TRIM was originally devised to provide transparent mobility support in the IMS, although transparency came at the cost of using a suboptimal data path between communicating end points. TRIM+ ...

This talk describes an algorithm which identifies times of emotional discontinuity as reflected in social media. The talk formulates the optimization problem to solve to best explain the social media data, develops an algorithm to solve it, and illustrates the new method by analyzing mood shifts reflected in 380,000 Twitter messages related to one of the world's most popular soccer teams, Manch...

Expressions relating the bispectral reflectance of a stack of n fluorescing layers to each individual layer's reflectance and transmittance are derived. This theoretical framework is used together with recently proposed extensions of the Kubelka-Munk model to study the fluorescence from layered turbid media. For one layer over a reflecting background, the model is shown to give the same results...

Background: The optimization of bioprocess conditions towards improved growth profile and productivity yield is considered of great importance in biopharmaceutical manufacturing. Peptones as efficient sources of nutrients have been studied for their effect on media development however, their role on metabolic pathway is not well understood. Methods: In the present study, the effect of different...
