Internet world is characterized by many users among which are crackers and thieves. Hence, the need for a secured system to safely exchange confidential information among users across the web is required. Of such tool is steganography that simply hides…

Resumen de la tesis del autor para obtener el grado de Magister en Redes de Datos de la Facultad de Informática de la UNLP, dirigida por Luis Armando Marrone.

Professor Arnold Kaufmann did propose
at least two types of indexes for estimating fuzziness in
finite standard fuzzy sets. First one has an analogue
formulation to that stated by Claude Shannon for
measuring uncertainty in a given system. Shannon
formulation…

This paper addresses the problem of contour line extraction from scanned topographic maps in poor condition. A novel method is developed, using knowledge of cartography and graphics to extract contours by removing other layers which overlay the contours, and reconstructing…

This paper introduces the conceptual design of a new information technology integrating wireless telephony and Internet services to assist in locating lost or displaced people in a moment of crisis. This public safety service is based on a novel text…

Current performance prediction analytical models try to characterize the performance behavior of actual machines through a small set of parameters. Due to different factors, the predicted times suffer substantial deviations. A natural approach is to associate a different proportionality constant…

The performance of two selection mechanisms used in the most popular variant of differential evolution, known as DE/rand/1/bin, are compared in the solution of constrained numerical optimization problems. Four performance measures proposed in the specialized literature are used to analyze…

The very beginning of the research on Smart Adaptive Web Systems (SAWS). They are systems that adapt their response based on the context in which they are used. In AWS, three main sources of information have been identified are: user,…

There s some very important meaning in the study of realtime face recognition and tracking system for the video monitoring and artifical vision. The current method is still very susceptible to the illumination condition, non-real time and very common to…

An accurate procedure for evaluating the strong correlation and conflicting goals of coverage, capacity and Quality of Service (QoS) is required for efficient planning of 3G radio networks. In this paper, we explore and implement an agent-based simulation methodology which…
