The goal of this paper is to give explicit procedures and equations for performing metric multidimensional scaling to surfaces. More specifically, we describe a method for determining a configuration of points in a closed and orientable surface (i.e.

This article describes an application of research that sits at the intersection of commutative algebra and combinatorics: Betti numbers of graphs. In particular, we describe a correspondence between simple undirected graphs and a class of ideals in a

This paper examines the use of three feature sets for object classification in aerial imagery. The first feature set is based on affine invariant functions of the central moments computed on the objects within the image. The second feature set employ

Confining potentials in euqations involving the interaction of fermions lead to no Klein paradoxes if the strength of the vector potential is appropriately limited compared to the scalar potential. For linear potentials the Regge trajectories are asy

With alexandrite laser systems producing tens of watts now developed, it is interesting to consider how powerful a system could be developed through the scaling up of existing designs. The most logical starting point for such a scaling is the 150 W s
