    In this paper we attempt online person identification by signature recognition and also from the natural writing of a person. The basic interest is in the novelty of the technique and the methodology utilized. Our system is based on a newly developed spatio-temporal artificial neuron (STAN), which is well adapted for the recognition of spatio-temporal patterns. This neuron has the capability to pr...

    This paper describes fuzzy control theory to modulate the input signal for static Var compensator (SVC) to enhance power system stability. Static Var compensator, which is the first generation of FACTS devices, increases power transfer and improves the damping of electromechanical oscillations when used in transmission systems. The proposed control system for SVC is based on fuzzy set theory. The ... View full abstract»

    This contribution presents a low-complexity camera egomotion estimation algorithm for real-time applications. The algorithm uses a feature based approach for motion estimation. A new method is introduced for feature selection which limits the number of feature points to be tracked and has a low dependency on structure in the image. Both these factors are important in real time, applications, as le... View full abstract»

    Classification of spatial data can be difficult with existing methods due to the large numbers and sizes of spatial data sets and a large volume of data requires a huge amount of memory and/or time. The task becomes even more difficult when we consider continuous spatial data streams. In this paper, we deal with this challenge using the Peano count tree (P-tree), which provides a lossless, compres... View full abstract»

    The point location problem is an important and fundamental problem in computational geometry. A point location method that is extensively used is Kirkpatrick's method. Previous attempts to improve the method were based on allowing only the vertices with degree not exceeding a certain value to be removed at each stage. In this paper we present an approach for reducing the query time based on a diff... View full abstract»

    Software companies need to know how their projects performed - which of their projects were successful and which of their projects failed. Although identifying a failed project from a successful project is an easy task; but identifying the relative success of projects is not that trivial. This paper suggests a framework that can be used to evaluate the relative performance of software projects. View full abstract»

    The RF/microwave circuit design and analysis, from inception to culmination extensively utilizes and depends on and scattering (S-) parameters. S-parameter data can either be obtained through measurements or simulations or by evaluating closed form expressions. Measurement of S-parameter, while most accurate, is not always possible or convenient. In the recent past, artificial neural networks (ANN... View full abstract»

    In this paper, we outline a novel technique for robust indexing and retrieval of video object trajectories. Our approach is based on using spatiotemporal curvature to represent the trajectories. Dominant inflection points from the curvature are extracted at multiple levels of scale simultaneously revealing structure at varying levels of details. These inflection points, the maxima of curvature sca... View full abstract»

    We present an approach to parsing relative clauses in Arabic in the tradition of the Paninian grammar framework which leads to deriving a common logical form for equivalent sentences. Particular attention is paid to the analysis of resumptive pronouns in the retrieval of syntactico-semantic relationships. The analysis arises from the development of a lexicalised dependency grammar for Arabic that ... View full abstract»
