On Approximation Lower Bounds for TSP with Bounded Metrics
We develop a new method for proving explicit approximation lower bounds for TSP problems with bounded metrics improving on the best up to now known bounds. They almost match the b...

Software requirements validation via task analysis
As a baseline for software development, a correct and complete requirements definition is one foundation of software quality. Previously, a novel approach to static testing of sof...

A comparison of regularizations for an ill-posed problem
Abstract. We consider numerical methods for a “quasi-boundary value” regularization of the backward parabolic problem given by ut + Au = 0 , 0 < t < T u(T ) = f, where A ...

Continuous-time hidden Markov models for network performance evaluation
In this paper, we study the use of continuous-time hidden Markov models (CT-HMMs) for network protocol and application performance evaluation. We develop an algorithm to infer the...

Cooperative probabilistic state estimation for vision-based autonomous mobile robots
Abstract--With the services that autonomous robots are to provide becoming more demanding, the states that the robots have to estimate become more complex. In this article, we deve...
