Os efeitos da adição de P e N e suas interações sobre a germinação de esporos, crescimento e extensão de raízes de Anthylis vulneraria sub sp. Sampaiana (Kidney vetch) RiT-DNA transformadas e colonizadas por Glomus etunicatum Becker & Gerdemann (INVAM…

Mobile agent systems have received important attention in the last years as a new programming paradigm for widely distributed and heterogeneous systems. In this article, a multi-paradigm approach for the development of intelligent mobile agents is presented. It integrates both…

In this work a compiler from fork specifications into logic programs is presented. The technique implemented by the compiler consists of transforming a set of fork equations (with some restrictions) into normal logic programs in such a way that the…

In a general context we introduce image processing with 1-dimensional wavelets and show the diferences with nonseparable 2-dimensional wavelets having quincunx decimation, in the first place, and with balanced nonseparable 2-dimensional multiwavelets, in the second place. All of them are…

In this paper we show an algorithm for dynamic reconfiguration of distributed applications based on the mobile agent model. We also show that the proposed algorithm can be easily implemented in the IPL language, a language with several abstractions for…

In the last years there has been and increasing demand of a variety of logical systems, prompted mostly by applications of logic in AI, logic programming an other related areas. Labeled Deductive Systems (LDS) were developed as a flexible methodology…

This paper presents an evolution of a simulation environment where situations in which a DDB should maintain data integrity are modeled and implemented. These situations include failures taking place during transactions, and the focus is mainly on the utilization and…

Parallel computing on networks of workstations are intensively used in some application areas such as linear algebra operations. Topics such as processing as well as communication hardware heterogeneity are considered solved by the use of parallel processing libraries, but experimentation…

Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel perfor-mance against the local interactive response. Explicit and implicit coscheduling techniques in a…

Within the context of multi-agent systems, an agent may often find itself in a position where it receives information through informants. These informants are independent agents who have their own interests and, therefore are not necessarily completely reliable. It is…
