The security of digital information in modern times is one of the most important factors to keep in mind. For this reason, in this paper, the author has proposed a new standard method of image encryption. The proposed method consists of 4 different stages: 1) First, a number is generated from the password and each pixel of the image is converted to its equivalent eight binary number, and in tha...

In this paper, the author presents an advanced version of image encryption technique, which is itself an upgraded version of SD-EI image encryption method. In this new method, SD-EI Ver-2, there are more bit wise manipulations compared to original SD-EI method. The proposed method consist of three stages: 1) First, a number is generated from the password and each pixel of the image is converted...

Present firm growth literatures, with notable few exceptions, tend to be static explanations and qualitative suggestions, failing to validate whether the causal ambiguity hidden inside specific growth patterns is completely and correctly explained. Without objective knowledge and information of causal ambiguity, the enhancement of firm strategy formulation process can be rather difficult. In co...

This paper proposes an automatic algorithm for the montage of OCT data sets, which produces a composite 3D OCT image over a large field of view out of several separate, partially overlapping OCT data sets. First the OCT fundus images (OFIs) are registered, using blood vessel ridges as the feature of interest and a two step iterative procedure to minimize the distance between all matching point ...

S(pacelike)D-branes are objects arising naturally in string theory when Dirichlet boundary conditions are imposed on the time direction. SD-brane physics is inherently time-dependent. Previous investigations of gravity fields of SD-branes have yielded undesirable naked spacelike singularities. We set up the problem of coupling the most relevant open-string tachyonic mode to massless closed-stri...

The presenter’s study: (1) investigated the underpinnings for a drive in the search for a better quality of life; (2) formulated a basis for a realistic state of happiness; (3) investigated an overview of ICHPER·SD through examining its history in 4 periods: (a) from the founding in 1958 to 1991 as the first segment; (b) from 1991 to 2001 as the 2 segment; (c) from 2003 to 2011 as the 3 segment...

Continuing our recent research on embedding properties of generalized soluble and generalized nilpotent groups, we study some embedding properties of SD-groups. We show that every countable SD-group G can be subnormally embedded into a two-generator SD-group H. This embedding can have additional properties: if the group G is fully ordered, then the group H can be chosen to be also fully ordered...

We introduce and characterize a new solution concept for TU games. The new solution is called SD-prenucleolus and is a lexicographic value although is not a weighted prenucleolus. The SD-prenucleolus satis…es several desirable properties and is the only known solution that satis…es core stability, strong aggregate monotonicity and null player out property in the class of balanced games. The SD-...
