This brief revisits the problem of conversion between number systems and asks the following question: given a nonnegative decimal number , what is the value of the digit at positio...
In this paper we introduce variable resolution 4– meshes, a powerful structure for the representation of geometric objects at multiple levels of detail. It combines most propert...
In this paper, we study the minimum spanning tree problem for vertex-labeled graphs, where the weights of edges may vary depending on the selection of labels of vertices at both e...
In many applications, the underlying data (the web, an XML document, or a relational database) can be seen as a graph. These graphs may be enriched with weights, associated with t...
Cloud computing has emerged as a promising environment capable of providing flexibility, scalability, elasticity, failover mechanisms, high availability, and other important feat...
