Optimal Codeword Design for Precoded UWB (PUWB) Systems
Abstract— A precoding technique applied to symbols transmitted in an ultra-wideband (UWB) system was proposed in [1], which can concentrate the signal power at the receiver to fa...

A hybrid model of evolutionary algorithms and branch-and-bound for combinatorial optimization problems
Abstract- Branch-and-Bound and evolutionary algorithms represent two very different approaches for tackling combinatorial optimization problems. These approaches are not incompatib...

Optimizing Robustness While Generating Shared Secret Safe Primes
We develop a method for generating shared, secret, safe primes applicable to use in threshold RSA signature schemes such as the one developed by Shoup. We would like a scheme usabl...

A Sensitivity Analysis of a Cooperative Coevolutionary Algorithm Biased for Optimization
Abstract. Recent theoretical work helped explain certain optimizationrelated pathologies in cooperative coevolutionary algorithms (CCEAs). Such explanations have led to adopting sp...

Real-Time Facial Feature Extraction by Cascaded Parameter Prediction and Image Optimization
We propose a new fast facial-feature extraction technique for embedded face-recognition applications. A deformable feature model is adopted, of which the parameters are optimized t...
