The field of epileptic seizure prediction is today highly relevant not only for elucidating underlying brain dynamical mechanisms but also from a technological (and medical industry) perspective. In this paper, a bird's eye view of the state-of-the-art in this truly cross-disciplinary research field is presented. It describes the chronological path of the major results achieved in recent years. Once the relevant background is depicted Read More

In this paper we survey the literature of both Knowledge Representation and Civil Engineering regarding the Applications of Knowledge Representation and Reasoning Techniques to Civil and Structural Engineering. The reviewed works are analysed in terms of the scope, objectives and approach employed in the investigation, and compared to each other based on a preliminary analysis of the problems posed by the Read More

Quadratic Programming (QP) represents a special class of nonlinear programming where the objective function is quadratic and constraints are linear. QP can also be viewed as a generalization of linear programming. When real-world applications are considered, vagueness appears in a natural way, and hence it makes perfect sense to think of fuzzy quadratic programming problems. This way of problem modeling is appli Read More

Single-sensor technology is a popular imaging approach used in image-enabled consumer electronic devices such as digital still and video cameras, mobile phones, personal digital assistants, and visual sensors for surveillance and automotive applications. Cameras make use of an electronic sensor (Charge Coupled Device - CCD - or Complementary Metal-Oxide-Semiconductor - CMOS) to acquire the spatial variations in light i Read More

Mobile telecommunications is nowadays one of the most successful technological fields nowadays. Since its introduction in the global market in the last decade of the previous century, it became a very important contributor to the Gross Domestic Product (GDP) of developed and developing countries. In this market, a large number of powerful international telecommunications companies, often in harsh competition among th Read More

Mixture of Gaussians is a widely used approach for background modeling to detect moving objects from static cameras. Numerous improvements of the original method developed by Stauffer and Grimson [1] have been proposed over the recent years and the purpose of this paper is to provide a survey and an original classification of these improvements. We also discuss relevant issues to reduce the computation time. F Read More
