The GAMA pattern language provides patterns for supporting dynamic teams with computer technology. In this document, a small subset of the GAMA language is presented that deals with spontaneous group formation based on common interests.

Agent-based models tend to be more and more complex. In order to cope with this increase of complexity, powerful modeling and simulation tools are required. These last years have seen the development of several platforms dedicated to the development of agent-based models. While some of them are still limited to the development of simple models, others allow to develop rich and complex models. A...

Este trabalho estudou os efeitos da radiação gama como indutora da imobilização de fases estacionárias líquidas de polidimetilsilicones usadas para separações cromatográficas em colunas recheadas. Testes de extração em solventes mostram que doses moderadas de radiação gama (80-140 kGy) produzem imobilização (90%) da maioria dos polidimetilsilicones testados em suportes do tipo Chromosorb, apesa...

A standard genetic algorithm for sorting unsigned genomes by translocations is improved in two different manners: 1. a memetic algorithm (GAMA ) is provided, which embeds a new stage of local search, based on the concept of mutation applied in only one gene; 2. an oppositionbased learning (GAOBL ) mechanism is provided, which explores the concept of internal opposition applied to a chromosome. ...

The Group Allocation Multiple Access with Collision Detection (GAMA/CD) protocol for scheduling variable-length packet transmissions in a local area network is speciied and analyzed. GAMA/CD provides the advantages of both TDMA and CSMA/CD by maintaining a dynamically-sized cycle that varies in length depending on the network load; each cycle is composed of a contention period and a group-trans...

The Group Allocation Multiple Access (GAMA) protocol for scheduling variable-length packet transmissions in a single-hop packet-radio network is specified and analyzed. By maintaining a dynamically-sized cycle that changes in length depending on the amount of network traffic, GAMA is able to provide the advantages of both TDMA and CSMA. Each cycle contains a contention period and a group-transm...

In this article, we consider market places as social places. Social places provide social presence and interaction. Virtual market places often lack in these social factors. Community support tools, such as chat systems or newsgroups try to fill this gap. We argue that a new architecture is needed that brings together customers with common interests. We propose a combined system called GAMA-Mal...

The GAMA survey aims to deliver 250,000 optical spectra (3–7Å resolution) over 250 sq. degrees to spectroscopic limits of rAB < 19.8 and KAB < 17.0 mag. Complementary imaging will be provided by GALEX, VST, UKIRT, VISTA, HERSCHEL and ASKAP to comparable flux levels leading to a definitive multi-wavelength galaxy database. The data will be used to study all aspects of cosmic structures on 1kpc t...
