Experiencing minix as a didactical aid for operating systems courses

Minix is a Unix clone Operating Systems to be run on IBM PCs and compatibles, designed by Tanembaum [10] for courses in the area.Accepting the Tanembaums proposal, this document describes the results of some extensions on the internal work of Minix as an exercise on Operating Systems Design and Implementation that attempts to transfer that experience to other groups of interest.The paper intends to be interpreted as a report remarking what kind of work was done having at our disposal an extensively documented copy of the source code of an operating system, taking into account that the developers are undergraduates in Computer Science.Further details on implementations will be available in future publications [1], [4], [6].

An argumentation-based BDI personal assistant

BDI models and argumentation-based approaches are powerful tools that can play a fundamental role in implementing intelligent systems for complex business and industrial problems. Some recent works have started studying the integration of both approaches from a theoretical point of view. However, little effort has been made to analize how these technologies can be effectively integrated in complex systems which require the use of well-known development resources, such as agent development platforms and other programming tools. This work addresses that problem, showing how an argumentation-based reasoning service can be used in different components of a BDI agent implemented with a Jadex platform. All the concepts involved in our proposal are exemplified by designing and implementing a travel assistant agent that allows to observe how BDI and argumentation approaches can be effectively integrated in a working system developed with freely available technologies.

Design features of high level layers in LAHNOS, a local area heterogeneous network operating system

This paper describes the kernel and user interface designs of a Network Operating System for a Local Heterogeneous Area Network. The main goal of the project is to create a kernel to manage the distribution of a restricted set of functions or services between the network nodes, allowing portability of these functions within machine and Operating Systems heteregeneities upon which the kernel is built.Facing the problem throughout the Object and Client-Server Paradigms we attempt to provide the user with a dynamic availability of, till now isolated, resources by means of a user-friendly interface.
