Dynamic normal forms and dynamic characteristic polynomial
Abstract. We present the first fully dynamic algorithm for computing the characteristic polynomial of a matrix. In the generic symmetric case our algorithm supports rank-one updat...

Performance Evaluation of a Metro WDM Multi-channel Ring Network with Variable-length Packets
— In this paper, we discuss and evaluate our two metro wavelength division multiplexing (WDM) ring network architectures for variable-length packet traffic. The paper begins with...

A recursive filter for linear systems on Riemannian manifolds
We present an online, recursive filtering technique to model linear dynamical systems that operate on the state space of symmetric positive definite matrices (tensors) that lie on...

Blur and Contrast Invariant Fast Stereo Matching
We propose a novel approach for estimating a depth-map from a pair of rectified stereo images degraded by blur and contrast change. At each location in image space, information is...

Optimal Partitions in Additively Separable Hedonic Games
We conduct a computational analysis of partitions in additively separable hedonic games that satisfy standard criteria of fairness and optimality. We show that computing a partiti...
