Maximizing the Lifetime of a Barrier of Wireless Sensors
—To make a network last beyond the lifetime of an individual sensor, redundant sensors must be deployed. What sleep-wakeup schedule can then be used for individual sensors so tha...

Trajectory Segmentation Using Dynamic Programming
We consider the segmentation of a trajectory into piecewise polynomial parts, or possibly other forms. Segmentation is typically formulated as an optimization problem which trades...

Heterogeneous Architecture Exploration: Analysis vs. Parameter Sweep
This paper argues the case for the use of analytical models in FPGA architecture layout exploration. We show that the problem when simplified, is amenable to formal optimization t...

Factorized variational approximations for acoustic multi source localization
Estimation based on received signal strength (RSS) is crucial in sensor networks for sensor localization, target tracking, etc. In this paper, we present a Gaussian approximation ...

An Approach to Capture Design-induced Error Using an Ontology
Since engineered systems, e.g. aviation control, have increasingly equipped with automated and computer-supported artifacts, human-system interaction has been an important issue. U...
