A survey of agent-oriented methodologies

This article introduces the current agent-oriented methodologies. It discusses what approaches have been followed (mainly extending existing object oriented and knowledge engineering methodologies), the suitability of these approaches for agent modelling, and some conclusions drawn from the survey

Una comunidad de construcción de conocimiento: el caso de la maestría en ingeniería de la UADY

Se desea estudiar la construcción de conocimiento en una comunidad epistémica, entendida como una comunidad de práctica (CoP) por medio del uso de conocimiento matemático. Se analiza el uso de las gráficas de variación y cambio en tesis, revistas de investigación y notas de clases de la Maestría en ingeniería de la Universidad Autónoma de Yucatán (UADY) en tres diferentes escenarios de interacción, a los cuales denominamos episodios: clases de la maestría, productos de investigación y con el asesor; en todos los escenarios las personas son expertos (profesores investigadores) y aprendices (alumnos en diferentes etapas) de la especialidad de ingeniería ambiental, construcción y estructuras. Se presentarán algunos avances referentes al método y cómo se inicia el análisis de la información para evidenciar la construcción de conocimiento, todo ello de acorde con la problemática

Individual Differences in Virtual Environments

This paper summarises the results of several studies of individual differences among users navigating in virtual environments.These differences relate to performance of navigational tasks, and the degree of sense of presence experienced by the users. The individual differences addressed in this paper refer primarily to personality and demographic factors. The possibility of improving the design of virtual environments for a better accommodation of these differences is discussed

Agent chameleons: Virtual agents real intelligence

Abstract. Agent Chameleons provides virtual agents powered by real intelligence, delivering next generation autonomic entities that can seamlessly migrate, mutate and evolve on their journey between and within physical and digital information spaces.

Agent Chameleons: Migration and Mutation within and between Real and Virtual Spaces

This paper introduces the concept of Agent Chameleons and investigates the motivation, desire and possibilities of agent migration and mutation within and between real and artificial spaces. Information spaces manifest themselves in many forms. Benefits exist where the agent/user is immersed and feels a sense of presence within such spaces. Agents often take on an embodied form. This form embodies the agent together with its associated behaviours and capabilities. The agent behaviour is inextricably mediated by a set of laws, the agent physics laws. This paper investigates the possibility of agents seamlessly migrating across traditional impervious inter-world boundaries and the associated possibility of agent forms mutating in order to empower itself. Such mutation may occur as the agent context changes. Context shifts can occur as the agent migrates from one world to another or indeed when environmental factors change within a given world

Delivering Adaptivity through Context Awareness

Developing applications and deploying services for mobile users raises a number of issues and challenges that must be successfully addressed before the era of truly ubiquitous computing will dawn. In particular, the desire to deploy rich multimedia applications and services is severely curtailed by the limited capabilities of the current range of mobile devices as well as the limited bandwidth of current wireless cellular networks. How best to overcome these limitations remains the focus of much research. Intelligent agents have been demonstrated as a promising solution for inherently complex and dynamic domains and their use is proposed as the basis of a solution for assembling and disseminating multimedia content to a mobile audience. Attention is particularly directed to issues concerning the adaptation of content according to the end-user physical context and their personal profile or model.TS 27.06.1

NEXUS: Mixed Reality Experiments with Embodied Intentional Agents

This paper seeks to erode the traditional boundaries that exist between the physical and the virtual world. It explores mixed reality experiences and the deployment of situated embodied agents that offer mediation in the control of, and interaction between, avatars. The NEXUS system is introduced which facilitates the construction and experimentation with mixed reality multi-character scenarios

The Effects of Deployment Irregularity on Coverage in Wireless Sensor Networks

One commonly employed method to calculate whether a wireless sensor network can adequately sense the entirety of a region of interest is to define the area that a sensor can monitor and ensure that the union of all these areas leaves no part of the region uncovered. This paper shows the results of a series of experiments in simulation designed to show how various degrees of deviation from intended node placement locations in a wireless sensor network affect the achievable coverage using this model. The main result is that irregular deployments are only slightly less efficient than highly regular ones but that since they have less redundancy they fail before regular cases. This is manifested by the regular patterns maintaining coverage by increasing the number of active nodes while the irregular ones fail to achieve coverage despite having activated a low proportion of the available nodes due to the remaining nodes being situated at ineffective locations
