The use of probabilities for data correction and data fusion
Abstract: Typically, any instrument of measure (called a "captor") makes mistakes; the error is usually not constant on the whole range of measure: the captor is less precise at the endpoints. Besides the initial calibration of the captor, these errors should be taken into account in practical exploitation, as a theoretical study shows. If now two or more captors are used for the same observation, usually their indications are not exactly the same. How should one combine the indications given by each captor? The answer is given in terms of proabilities, using conditional laws and conditional expectations. In other terms, we show that probablilities provide the proper frame to deal with every-day engineering problems, such as measure of distances, which are usually thought to be completely deterministic. Using this approach, we could improve the final precision of an infra-red guided missile by a factor 10. This talk is suitable for a general audience

Toric varieties
Abstract: The purpose of this talk is to introduce toric varieties as a starting point for algebraic geometry and algebraic group actions. We will explain the relationship between algebraic geometry and combinatorial geometry and see how this is the result of a group action by an embedded algebraic torus. Several examples will be employed to illustrate these ideas throughout the lecture. No prior knowledge of this subject area will be assumed.
