Mecanismos para Intercâmbio de Dados Geográficos através de Web Services

This paper proposes an interchange mechanism for geographic data through the use of intermediate Web Services. We also present an auxiliar software that codes geographic Web Services according to the OpenGIS specifications. The main objective of this work is facilitate the creation, publication and consumption of geographic Web Services.

Despliegue de monitores con los mecanismos de reflexión y las extensiones de gestión de Java

Monitoring process let self-adapting systems to watch their current state and therefore making the needed changes. Deploying monitors into a system involves adding the necessary statements into the source code and the possibility to impact the system’s performance during execution, also if monitors use reflection mechanisms. This paper features a scheme to deploy monitors on compiled systems, r...

Estudo de mecanismos de segurança para proteção do roteamento em redes de sensores sem fio

Wireless Sensor Networks (WSN) are more subject to enemy action than conventional networks due to their hardware and energy constraints and due to hostile environment in which they can be inserted. This scenario is too favorable to denial of service attacks, especially in routing function, one critical function in any network. This work is focused in routing protecting in WSN. It presents a stu...

Evolución diferencial con memoria de parámetros para la optimización de mecanismos de cuatro barras

L-SHADE is an algorithm based on differential evolution wich automatically adapts the parameters related to mutation (F ) and crossover (CR) using a parameter memory. L-SHADE also controls the population size (NP ) with a linear function. In this work, a constrainthandling technique is added to L-SHADE to optimize three four-bar
