On (q + t, t)-Arcs of Type (0, 2, t)
In this paper we construct an infinite series of (q + t, t)-arcs of type (0, 2, t). We show that this construction includes the Korchm?aros-Mazzocca arcs, and we gain new infinite...

Relative widths of smooth functions determined by fractional order derivatives
For two subsets W and V of a normed space X. The relative Kolmogorov n-width of W relative to V in X is defined by Kn(W, V )X := inf Ln sup f W inf gV Ln f - g X, where the infimu...

Approximating the Generalized Capacitated Tree-Routing Problem
In this paper, we introduce the generalized capacitated tree-routing problem (GCTR), which is described as follows. Given a connected graph G = (V, E) with a sink s V and a set M...

Subdomain Aware Contour Trees and Contour Evolution in Time-Dependent Scalar Fields
For time-dependent scalar fields, one is often interested in topology changes of contours in time. In this paper, we focus on describing how contours split and merge over a certa...

Application of sparse signal recovery to pilot-assisted channel estimation
We examine the application of current research in sparse signal recovery to the problem of channel estimation. Specifically, using an Orthogonal Frequency Division Multiplexed (O...
