We present a spring-embedder model for drawing rooted and unrooted phylogenetic trees with straight edges. Our heuristic strives for uniform edge lengths, and we develop it in analogy to forces in natural systems, for a simple, elegant, conceptually intuitive, and efficient algorithm. These algorithms are implemented on a web-based phylogeny visualization system that interoperates with existing...

In this paper we propose a new technique for image segmentation based on contour detection using image analogies principle. A set of artificial patterns are used to locate contours of any query image. Each pattern allow the location of contours corresponding to specific intensity variation. Boundaries are extracted based on the properties of located contours. In addition, elementary regions der...

Analogy is a special kind of similarity (see Goldstone & Son, Chap. 2). Two situations are analogous if they share a common pattern of relationships among their constituent elements even though the elements themselves differ across the two situations. Typically, one analog, termed the source or base, is more familiar or better understood than the second analog, termed the target. This asymmetry...

the well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. a new model that was previously proposed by the authors that combines a mass with a pulley (mp) is shown to simulat...

Thinkers and philosophers have constantly benefited from different         approaches of reasoning to explore and justify their ideas. Theses reasoning            approaches are considered as the principle instruments in speculative activities of the thinkers. To this end to achieve the procedure of thinking and the way philosophers achieve objectives, it is necessary to recognize their reasoni...
