this article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. it is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...

The UNIX grep utility marked the birth of a global regular expression print (GREP) tools. Searching for patterns in text is important operation in a number of domains, including program comprehension and software maintenance, structured text databases, indexing file systems, and searching natural language texts. Such a wide range of uses inspired the development of variations of the original UN...

In this paper a method is presented for calculating the eigenvalues of perturbed matrices corresponding to their initial and unperturbed state. other word, instead solving eigenvalue problem matrix with size (n x n), only it sufficient solve dimension (m m) where m less than n difference – considerable. By means method, frequencies near regular structures considering those are calculated.

striking disparities in access to healthcare and in health outcomes are major characteristics of health across the globe. this inequitable state of global health and how it could be improved has become a highly popularized field of academic study. in a series of articles in this journal the roles of power and politics in global health have been addressed in considerable detail. three points are...

In an increasingly interconnected world, the development of computer friendly systems for the display and analysis of global data is an important issue. This paper concerns a method for computer representation and manipulation of global data based on multi-resolution subdivisions of regular polyhedra. In particular, the problem of efficiently indexing the cells of such a discrete global grid is...
