Sensor localization is a fundamental and crucial issue for wireless sensor networks operation and management. Accurate self-localization capability is highly desirable in wireless sensor network. A fundamental problem in distance-based sensor network localization is whether a given sensor network is uniquely localizable or not. Flip ambiguity is a main(More)
Multi-core architectures, which have multiple processing units on a single chip, are widely viewed as a way to achieve higher processor performance. Well scheduling of running threads on these processors will result in achieving higher performance. Modern multi-core systems are designed to allow clusters of cores to share various hardware structures, such(More)
Estimating the head pose of a human is a key task for human computer interaction, visual surveillance and face recognition applications hence an important problem in computer vision. Most of the works in this field suffer from lack of continuous estimating of the head pose. Fuzzy systems are known as universal approximator capable of approximating an(More)
As processing power becomes cheaper and more available by using cluster of computers, the needs for parallel algorithms, which can harness these computing potentials, are increasing. Automatic database normalization is an application of parallel algorithms. Normalization is the most exercised technique for the analysis of relational databases. It aims at(More)
Estimating the head pose plays an important role in computer vision and also as a key task for visual surveillance and face recognition applications hence a prominent problem in computer vision. Most of the works in this field suffer from lack of continuous estimating of the head pose and high accuracy. We know fuzzy systems as universal approximator(More)
