Robotic agents in dynamic environments must sometimes navigate using only their local perceptions. In complex environments, features such as terrain undulation, geometrically complex barriers, and similar obstacles form local maxima and minima that can trap and hinder agents using reactive navigation. Moreover, agents navigating in a purely reactive fashion forget their past discoveries quickly...

Introduction In this position paper, we highlight some of the things we have learned over the past 15 years in our experience with software architectures. Much of what we have learned results from our experience in the specification, design, implementation and evolution of software engineering environments and process-driven software environments. Along the way, we have developed or used a vari...

Navigation is a fundamental human activity. It occurs in a wide range of activities and contexts, and it has accordingly been studied by a range of disciplines. In the social sciences, anthropologists have studied the tools and techniques of different cultures, including Western ones. Psychologists have studied the cognitive structures and processes involved in human navigation. In the field of...

Replication is one of the main techniques aiming to improve Web services’ (WS) quality of service (QoS) in distributed environments, including clouds and mobile devices. Service replication is a way of improving WS performance and availability by creating several copies or replicas of Web services which work in parallel or sequentially under defined circumstances. In this paper, a generalized r...

Current technology allows educational environments to offer teachers and students the functionality and the information required at any time, whatever the place and circumstance. Concretely, these environments mix three remarkable features: ubiquity, contextawareness and collaboration. Accordingly, a system which is developed with these three features can avoid oversights when performing tasks....

Radar systems have come a long way since their introduction in the 1940’s, today encompassing a broad range of applications, ranging from supermarket door openers to highly complex shipboard phased-array fire-control radars. Modern systems require higher performance to work in today’s ever more complex Electronic Warfare (EW) environments, which include jamming and deception. As a result, EW sy...

The development of intelligent tutoring systems has long been the focus of applying artificial intelligence and cognitive science in education. A new breed of intelligent learning environments called learning companion systems was developed over a decade ago. In contrast to an intelligent tutoring system, in which a computer mimics an intelligent tutor, the learning companion system assumes two...

In this paper, we propose a layered control architecture called “CBR augmented GP” to evolve robust control programs for humanoid robots. The key idea in our approach is to represent target task with abstract behaviors by Genetic Programming in simplified simulation and get a prototype of the control program then interpret it with Case-Based Reasoning (CBR) in the real world environments. Accor...

Distributed applications in evolving environments are typically difficult to maintain. Currently, human intervention is needed to maintain the application and adapt it to its changed environment. We need to: deploy application software on the added devices (buses), replace application software on the changed devices (e.g. to support the new advertisement display), and remove application softwar...

Ambient Intelligence (AmI) describes environments that sense and react to the humans in time to improve their living quality. Software agents are important in realizing such environments. While existing work has focused on individual agent’s reactions, more interesting applications will take place when the agents cooperate to provide composed services to humans. When cooperation is required, th...
