SUMMARY Longest path problem is a problem for finding a longest path in a given graph. While the graph classes in which the Hamiltonian path problem can be solved efficiently are widely investigated, there are few known graph classes such that the longest path problem can be solved efficiently. Polynomial time algorithms for finding a longest cycle and a longest path in a Ptolemaic graph are pr...
learning-oriented assessment seeks to emphasise that a fundamental purpose of assessment should be to promote learning. it mirrors formative assessment and assessment for learning processes. it can be defined as actions undertaken by teachers and / or students, which provide feedback for the improvement of teaching and learning. it also contrasts with equally important measurement-focused appro...
this study focuses on jane austens representation of her heroines in two of her novels: pride and prejudice, and mansfield park. i have concentrated only on a single idea: how jane austen takes her heroines through a course of psychogical reformation to which almost everything else in her novel is subsidiary. although i have discussed only pride and prejudice, we can trace austens carefully pla...
Scientists propose to understand the effect of music on human psyche, knowledge about soul, science, metaphysics, and spheres. At center all these discussions, we assume researchers are not focusing how triggers emotions. In this century live in, most writers agree that is crucial issue. Today’s want know why creates strong emotional reactions in people with scientific explanations. Our study a...
A graph is ptolemaic if and only if it is both chordal and distancehereditary. Thus, a ptolemaic graph G has two kinds of intersection graph representations: one from being chordal, and the other from being distance-hereditary. The first of these, called a clique tree representation, is easily generated from the clique graph of G (the intersection graph of the maximal complete subgraphs of G). ...
The science of astronomy in Iran, like some other places in the world, has a long history. According to the internal accounts and the travelogues of the European tourists, astronomy was one of the most noted sciences for the Safavid government, and was influential in all affairs including governmental and military affairs, celebrations, and mourning ceremonies. This study uses a descriptive-ana...
a paradigm shift. Kuhn argues that scientists in any field and in any time possess a set of shared beliefs about the world, and for that time the set constitutes the dominant paradigm. What he terms "normal science" proceeds nicely under this set of shared beliefs. Experiments are carried out strictly within the boundaries of those beliefs and small steps toward progress are made. An old but ex...
When Copernicus1 introduced a heliocentric model of the solar system, assuming circular trajectories of planets around the sun, his model yielded larger errors than the well-known and rather successful Ptolemaic model (for which the sun and stars were modeled as moving around the earth in a complicated orbit). Fortunately for Humanity, these large errors did not discourage Copernicus from using...
