Analysing distributed Internet worm attacks using continuous state-space approximation of process algebra models
Internet worms are classically described using SIR models and simulations, to capture the massive dynamics of the system. Here we are able to generate a differential equation-base...

High-rate, Double-Symbol-Decodable STBCs from Clifford Algebras
— For the number of transmit antennas N = 2a the maximum rate (in complex symbols per channel use) of all the Quasi-Orthogonal Designs (QODs) reported in the literature is a 2aâˆ...

A Lie Algebraic Approach for Consistent Pose Registration for General Euclidean Motion
Abstract— We study the problem of registering local relative pose estimates to produce a global consistent trajectory of a moving robot. Traditionally, this problem has been stud...
