An Implicit Motion Likelihood for Tracking with Particle Filters

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba

Particle filters are now established as the most popular method for visual tracking. Within this framework, it is generally assumed that the data are temporally independent given the sequence of object states. In this paper, we argue that in general the da ...

High Efficiency Road Status Monitoring System

Phillip Tomé, Telmo Cunha

This paper presents an application where an integrated GPS/IMU system is used for land survey (mounted on a van), providing a significant improvement on the efficiency of the road status monitoring process. Being initially developed for aircraft navigation ...

Evidence for two coupled subsystems in the superconducting state of La2-xSrxCuO4

Davor Pavuna, Mike Abrecht

We used a pump-probe technique to measure the transient change of optical reflectivity of both La2-xSrxCuO4, of various dopings, and slightly underdoped YBa2Cu3O7-x and NdBa2Cu3O7-x thin films. For the La2-xSrxCuO4 films, our data demonstrate the coexisten ...

Database Integration: the Key to Data Interoperability

Stefano Spaccapietra, Christine Parent

Most of new databases are no more built from scratch, but re-use existing data from several autonomous data stores. To facilitate application development, the data to be re-used should preferably be redefined as a virtual database, providing for the logica ...

Loss resilient decoding technique

Mohammad Amin Shokrollahi

An encoded message includes a plurality of data items and a plurality of redundant data items. Each of the redundant data items is associated with more than one of the data items. To decode the encoded message, a reduced first redundant data item is reduce ...

Modeling Spatial Data in the MADS Conceptual Model

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Pier Donini

Despite the well-established benefits of conceptual modeling for application design, current spatio-temporal conceptual models do not cope satisfactorily with designers' requirements. In this paper we first identify the goals of a spatio-temporal conceptua ...

Conceptual Modeling for Federated Geographical Information Systems over the Web

Stefano Spaccapietra, Christine Parent

A conceptual model provides the best support for federating heterogeneous datastores into a unified framework and elaborating a global consistent description of all available data. It therefore plays a central role for exchange of information within the co ...

A Framework for The Blackboard Model

The blackboard model is a flexible problem-solving approach where the data and knowledge rules are strictly separated. The data generated during a problem resolution, from a problem statement to a solution through various stages of inferences, is centrally ...

Structure of nanoscale silicon clusters

Wanda Andreoni, Michele Parrinello

Using the Car-Parrinello method, the authors have obtained unforeseen structures for the low-lying isomers of Si45 and other midsized Si clusters. They are formed by two shells of atoms, the outer one (cage) being fullerenelike and the inner one (core) con ...
