one of the aspects of the miracle of the quran is the relationship between the phonology and the music of holy verses with their meaning, which made profound impact even on those who are not deeply familiar with quran. arrangement of letters in terms of proximity and pronunciation, convergence and contrast characteristics, frequency and sequence of movements and their impact on the phonology an...

The construction of reduced order models for dynamical systems using proper orthogonal decomposition (POD) is based on the information contained in so-called snapshots. These provide the spatial distribution of the dynamical system at discrete time instances. This work is devoted to optimizing the choice of these time instances in such a manner that the error between the POD-solution and the tr...

Consumption of edible oils is increasing tremendously regardless their high prices. As a result, the global production vegetable has also been growing constantly. This may be related to population growth and associated demands consumers. In this particular work, ten crude food seed Ethiopian origin were extracted in our lab analyzed for chemical composition by gas chromatography mass spectrosco...

In this paper, two smoothing effects are firstly pointed out by analysis and by experiment on Traveling Salesman Problem(TSP) instances. We design a novel algorithm which runs stochastic local search under the SSS framework. The function determining the accepting probability of uphill moves is designed so that the algorithm can take advantage of the local smoothing effect ignored in original SS...

Multi-document person name resolution focuses on the problem of determining if two instances with the same name and from different documents refer to the same individual. We present a two-step approach in which a Maximum Entropy model is trained to give the probability that two names refer to the same individual. We then apply a modified agglomerative clustering technique to partition the insta...

Contrary to conventional belief, it turns out that in some problem instances of moderate size, fixed temperature simulated annealing algorithms based on a heuristic formula for determining the optimal temperature can be superior to algorithms based on cooling. Such a heuristic formula, however, often seems elusive. In practical cases considered we include instances of traveling salesman, quadra...

We focus on the random generation of SAT instances that have properties similar to real-world instances. It is known many industrial instances, even with a great number variables, can be solved by clever solver in reasonable amount time. This not possible, general, classical randomly generated provide different model called \emph{scale-free instances}. based use non-uniform probability distribu...
