Multicommodity Demand Flow in a Tree
We consider requests for capacity in a given tree network T = (V, E) where each edge of the tree has some integer capacity ue. Each request consists of an integer demand df and a ...

A Crystalline, Red Green Strategy for Meshing Highly Deformable Objects with Tetrahedra
Motivated by Lagrangian simulation of elastic deformation, we propose a new tetrahedral mesh generation algorithm that produces both high quality elements and a mesh that is well ...

A Lower Bound for Testing 3-Colorability in Bounded-Degree Graphs
We consider the problem of testing 3-colorability in the bounded-degree model. We show that, for small enough ε, every tester for 3colorability must have query complexity Ω(n)....

A low power direct digital frequency synthesizer with 60 dBc spectral purity
We present a low-power sine-output Direct Digital Frequency Synthesizer (DDFS) realized in 0.18 µm CMOS that achieves 60 dBc spectral purity from DC to the Nyquist frequency. No ...

Finding Multiple Routing Paths in Wide-Area WDM Networks
In this paper a multiple routing path problem in wide area Wavelength Division Multiplexing (WDM) networks is considered, which is to find K edge-disjoint lightpaths/semilightpat...
