Combining multiple altimeter missions

Simultaneous Crossover Adjustment for Contemporary Altimeter Missions

Since some time several altimeter satellites are operating simultaneously (ENVISAT, Jason-1, ERS-2, GFO, TOPEX/Poseidon). The large number of nearly simultaneous crossover events are used to estimate in a common adjustment radial error components of all altimeter missions. A discrete representation is used for the radial error components by minimizing both, crossover differences and consecutive...

Combining meteorites and missions to explore Mars.

Laboratory studies of meteorites and robotic exploration of Mars reveal scant atmosphere, no evidence of plate tectonics, past evidence for abundant water, and a protracted igneous evolution. Despite indirect hints, direct evidence of a martian origin came with the discovery of trapped atmospheric gases in one meteorite. Since then, the study of martian meteorites and findings from missions hav...

Multiple Medicaid missions: targeting, universalism, or both?

Multiple Robots For Multiple Missions: Architecture for Complex Collaboration

As systems of multiple robots become more prevalent both in research and in real world applications, they may be required to handle new missions, collaborate in teams they are not necessarily familiar with, and react, during mission execution, to changes in both the environment and in their own abilities. In this paper we describe a six-layered architecture that handles inherently these challen...

Combining Multiple Heuristics

In this work we introduce and study the question of combining multiple heuristics. Given a problem instance, each of the multiple heuristics is capable of computing the correct solution, but has a different cost. In our models the user executes multiple heuristics until one of them terminates with a solution. Given a set of problem instances, we show how to efficiently compute an optimal fixed ...
