Unifying JIAC Agent Development with AWE

Abstract. In this paper we describe the Agent World Editor, a tool for designing multi-agent systems and generating executable agent code. The tool also unifies the handling of different agent frameworks through an abstract agent model and an extensible transformation infrastructure. Currently, the tool supports three different agent frameworks of the JIAC family, and we feel confident that the approach holds for other frameworks as well as for the generation of multi-agent systems on heterogenous platforms

Proceedings of the 11th European Agent Systems Summer School Student Session

This volume contains the papers presented at the Student Session of the 11th European Agent Systems Summer School (EASSS) held on 2nd of September 2009 at Educatorio della Providenza, Turin, Italy. The Student Session, organised by students, is designed to encourage student interaction and feedback from the tutors. By providing the students with a conference-like setup, both in the presentation and in the review process, students have the opportunity to prepare their own submission, go through the selection process and present their work to each other and their interests to their fellow students as well as internationally leading experts in the agent field, both from the theoretical and the practical sector.

An integrated system for disabled people developed with the agent platform PANGEA

New trends in multi-agent systems call for self-adaptation and high dynamics, hence the new model of open MAS or virtual organization of agents. However, as existing agent platforms are not yet equipped to support this behavior, it is necessary to create new systems and mechanisms to facilitate the development of these new architectures. This article presents PANGEA, an agent platform to develop open multi-agent systems, specifically those including organizational aspects such as virtual agent organizations. The platform allows the integral management of organizations and offers tools to the end user. Additionally, it includes a communication protocol based on the IRC standard, which facilitates implementation and remains robust even with a large number of connections. The introduction of a CommunicationAgent and a Sniffer make it possible to offer Web Services for the distributed control of interaction. In order to test PANGEA, an integral system was developed to help the disabled, gathering a set of easily deployable and integrated services under a single architecture

Model for WCET prediction, scheduling and task allocation for emergent agent-behaviours in real-time scenarios

[ES]Hasta el momento no se conocen modelos de tiempo real específicamente desarrollados para su uso en sistemas abiertos, como las Organizaciones Virtuales de Agentes (OVs). Convencionalmente, los modelos de tiempo real se aplican a sistemas cerrados donde todas las variables se conocen a priori. Esta tesis presenta nuevas contribuciones y la novedosa integración de agentes en tiempo real dentro de OVs. Hasta donde alcanza nuestro conocimiento, éste es el primer modelo específicamente diseñado para su aplicación en OVs con restricciones temporales estrictas. Esta tesis proporciona una nueva perspectiva que combina la apertura y dinamicidad necesarias en una OV con las restricciones de tiempo real. Ésto es una aspecto complicado ya que el primer paradigma no es estricto, como el propio término de sistema abierto indica, sin embargo, el segundo paradigma debe cumplir estrictas restricciones. En resumen, el modelo que se presenta permite definir las acciones que una OV debe llevar a cabo con un plazo concreto, considerando los cambios que pueden ocurrir durante la ejecución de un plan particular. Es una planificación de tiempo real en una OV. Otra de las principales contribuciones de esta tesis es un modelo para el cálculo del tiempo de ejecución en el peor caso (WCET). La propuesta es un modelo efectivo para calcular el peor escenario cuando un agente desea formar parte de una OV y para ello, debe incluir sus tareas o comportamientos dentro del sistema de tiempo real, es decir, se calcula el WCET de comportamientos emergentes en tiempo de ejecución. También se incluye una planificación local para cada nodo de ejecución basada en el algoritmo FPS y una distribución de tareas entre los nodos disponibles en el sistema. Para ambos modelos se usan modelos matemáticos y estadísticos avanzados para crear un mecanismo adaptable, robusto y eficiente para agentes inteligentes en OVs. El desconocimiento, pese al estudio realizado, de una plataforma para sistemas abiertos que soporte agentes con restricciones de tiempo real y los mecanismos necesarios para el control y la gestión de OVs, es la principal motivación para el desarrollo de la plataforma de agentes PANGEA+RT. PANGEA+RT es una innovadora plataforma multi-agente que proporciona soporte para la ejecución de agentes en ambientes de tiempo real. Finalmente, se presenta un caso de estudio donde robots heterogéneos colaboran para realizar tareas de vigilancia. El caso de estudio se ha desarrollado con la plataforma PANGEA+RT donde el modelo propuesto está integrado. Por tanto al final de la tesis, con este caso de estudio se obtienen los resultados y conclusiones que validan el modelo

Social memory and ethnic identity: ancient Greek drama performances as commemorative ceremonies

This thesis is an ethnographic account of ancient Greek drama performances that take place in contemporary Greece. It illuminates an aspect of them that has not been taken into account until today: it treats them as commemorative ceremonies that produce, reproduce, and transmit social memory. The interrelation and interdependence between social memory and ethnic identity construction processes are analysed and it is shown that ancient drama performances, due to specific characteristics, constitute something more than mere theatrical events (as they are defined within the Western tradition). These performances, convey, sustain, and transmit from one generation to the next, perceptions of a glorious culture of the past, and become, for its creators and spectators, occasions for celebrating and remembering their ethnic past

Divine abandonment of Christ and the soul in Byzantine exegesis and ascetic literature

This thesis examines the role that the motif of divine abandonment played in the exegetical and ascetical literature of late antiquity. Divine abandonment of the soul was an integral part of the spiritual life. Its "normativeness" was related to the notion of divine paideia: God instructed the soul by abandoning the soul to ethical trials. This paideia had eschatological implications: divine abandonment highlighted the eschatological orientation of the Christian faith. Divine abandonment of Christ, however, is treated in Christological, rather than ascetical, terms. The experience of abandonment by the ascetics was not based on a "Christ-like" ethical model: Christ's abandonment was only connected to the ascetical abandonment within the scope of divine providence. The first part introduces the Patristic exegesis on the Song of Songs. It shows that Patristic exegesis related divine abandonment of the soul to ethical trials and highlights the role of the motif as part of divine paideia that leads the soul to an eschatological ethical perfection. The second part discusses Christ's abandonment on the cross, which Patristic literature handled with a certain hesitancy, even uncertainty. The last part examines the ascetical tradition. The motif illustrated God’s providential care for the ascetic soul where God remedied the soul's weakness and led her to the ethical fulfilment in the eschaton. This part also addresses the subtle way in which ascetical literature envisaged Christ as a spiritual model. The conclusion that this thesis draws is that it is within the theological framework of divine paideia and eschatology that the Patristic literature understood the notion of divine abandonment. Furthermore, it suggests that it is in this framework of their common tradition that the Eastern and Western spiritual traditions might mutually approach and understand each other
