Query Propagation in a P2P Data Integration System in the Presence of Schema Constraints
This paper addresses the problem of data integration in a P2P environment, where each peer stores schema of its local data, mappings between the schemas, and some schema constraint...

Aperiodic propagation criteria for Boolean functions
We characterise the aperiodic autocorrelation for a Boolean function, f, and define the Aperiodic Propagation Criteria (APC) of degree l and order q. We establish the strong simil...

Characterisation of RF propagation in metal pipes for passive RFID systems
: In this paper we extend the theory of Radio Frequency (RF) propagation as it relates to propagation within metal circular pipes. This work is motivated by a need to understand th...

A New Stereo Algorithm Integrating Luminance, Gradient and Segmentation Informations in a Belief-Propagation Framework
The paper deals with the design and implementation of a stereo algorithm. Disparity map is formulated as a Markov Random Field with a new smoothness constraint depending not only ...

Semantics of roundoff error propagation in finite precision calculations
We introduce a concrete semantics for floating-point operations which describes the propagation of roundoff errors throughout a calculation. This semantics is used to assert the co...
