Powder Electrostatics: Theory, Techniques and Applications

Emerging Optical CDMA Techniques and Applications

In this paper we present an in-depth review on the trends and the directions taken by the researchers worldwide in Optical Code Division Multiple Access (OCDMA) systems. We highlight those trends and features that are believed to be essential to the successful introduction of various OCDMA techniques in communication systems and data networks in near future. In particular we begin by giving a c...

Theory and Applications of Similarity Detection Techniques

The measurement of similarity between different objects is the fundamental function of any information retrieval, management, or data mining application. There are a number of ways to compute similarity or dissimilarity among various object representations. In a simplified classification these can be categorized as distance based, geometric, structural, feature and knowledge based techniques. T...

Diagrammatic Techniques in Perturbations Theory, and Applications

We want to discuss an approach to the study of perturbed systems in Classical Mechanics , based on methods characteristic of Quantum Field Theory (QFT). The starting point is to consider the perturbative expansion of the solution of the equations of motion: this leads to formal power series in the perturbative parameter, which were already considered and studied in the old papers by Newcomb, Li...
