During maintenance activities programmers make pervasive use of domain knowledge about the code that they maintain. Unfortunately, most of the current program analysis techniques do not explicitly take into consideration knowledge about the domain of the analyzed program. In this paper we advocate the need to use the domain knowledge explicitly in reverse engineering in order to enhance the cur...

This paper describes a method for converting an arbitrary mesh with irregular connectivity to a semi-regular multiresolution representation. A shape image encoding geometric and differential properties of the input model is computed. Standard image processing operations lead to an initial decomposition of the model that conforms to its salient features. A triangulation step performed on the res...

In this paper we presented technical study and security assessment that may threat the Arabic Domains in the new proposed multilingual domains (International domain Names IDN). We analyzed the Unicode Script (in particular the Arabic Scripts) and showed how vulnerable the proposed solution will be, then we presented suggestions for improved solution to be adapted to avoid future security risk w...

In cryptanalysis, security of ciphers vis-a-vis attacks is gauged against three criteria of complexities, i.e., computations, memory and time. Some features may not be so apparent in a particular domain, and their analysis in a transformed domain often reveals interesting patterns. Moreover, the complexity criteria in different domains are different and performance improvements are often achiev...
