Advances in networking technology have revitalized the investigation of agent technologyasapromisingparadigmforengineeringcomplexdistributedsoftware systems. Agent technology has been applied to a wide range of application - mains, including e-commerce, human-computer interfaces, telecommunications, and software assistants. Multi-agent systems (MASs) and their underlying t- ories provide a more natural support for ensuring important properties such as autonomy, mobility, environment heterogeneity, organization, openness, and intelligence. As a consequence, agent-based systems are likely to provide new - proaches to dealing with the complexity of developing and maintaining modern software. However, developing robust large-scale agent-based systems will - quire new software engineering approaches. There are currently many methods and techniques for working with individual agents or with systems built using only a few agents. Unfortunately, agent-based software engineering is still in its infancy and existing software engineering approaches are unable to cope with large MASs. The complexity associated with a large MAS is considerable. When a huge number of agents interact over heterogeneous environments, various phenomena occur which are not as easy to capture as when only a few agents are working together. As the multiple software agents are highly collaborative and operate in networked environments, they have to be context-aware and deal with - vironment uncertainty. This makes their coordination and management more di?cult and increases the likelihood of exceptional situations, such as security holes, privacy violations, and unexpected global e?ects. Moreover, as users and softwareengineersdelegatemoreautonomytotheirMASs,andputmoretrustin their results, new concerns arise in real-life applications.

Software Engineering for Multi-Agent Systems II

Nowadays, engineering large-scale software systems means dealing with complex systems composed of pervasive software components that move around and adapt to nondeterministic and open environments, like the Internet, in order to achieve systems design goals through the coordination of autonomously distributed services. The agent metaphor, in particular software agents and multi-agent systems (MAS), constitutes a promising approach for covering most of the software development life cycle, from conceptual modeling and requirements specification to architectural definition, design, and implementation. This book presents 17 carefully reviewed papers arranged in order to provide a coherent survey of how to exploit agent properties and MAS issues in today's software systems. The book offers the following topical sections: - software engineering foundations - requirements engineering and software architecture - coordination and mobility - reuse -dependability -empirical studies and applications

“Contos de Natal” reúne 10 narrativas curtas de autores brasileiros contemporâneos. Diferentes na forma e no estilo, o Natal funciona em todos os contos aqui apresentados como catalisador das angústias e dos dilemas da modernidade. Tema inesgotável (e fundador) da cultura ocidental, já serviu como ponto de partida para clássicos da literatura, pesquisas antropológicas e históricas e todo o tipo de aventura estética. Neste “Contos de Natal” vozes impactantes da literatura brasileira exploram as possibilidades do jogo da criação literária à partir de um início pré-determinado: o Natal. O tema da ressureição aparece em um dos contos e a personagem pensa: “acontece há dois mil anos, não sei porque você se espanta”. A verdade é que o tema segue nos espantando, assim como a boa literatura. Fruto da parceria entre a e-galáxia e a agência MTS, o livro conta com textos de: Alessandro Garcia, André de Leones, Cecilia Giannetti, Claudia Lage, Estevão Azevedo, Luís Carmelo, Luisa Geisler, Maria Clara Mattos, Toni Marques e Victor Heringer.
