In this document we give an overview of the CO-OPN/1.5 (Concurrent Object-Oriented Petri Nets) specification language and describe the features of each tool provided in the SANDS/1.5 (Structured Algebraic Net Development System) development environment. The CO-OPN/1.5 language is a specification language devised to support the development of large concurrent systems. The underlying...

Mobile software agents require a distributed execution environment in which they can command the use of many resources like memory, CPU time and bandwidth. While current research seems to concentrate on roaming agents at the application level and tries to define suitable high–level environments, we think that such an execution environment must be rooted at a very low-level. We argue...

The historical institutionalist tradition in comparative politics commonly assigns analytical primacy to political institutions. Whereas this polity-centeredness may be quite justifiable for purposes of comparative public policy, students of comparative political economy should pay systematic attention not only to economic institutions but also to a range of economic-structural...

In this paper we propose a robust version of Cox-type test statistics for the choice between two non-nested hypotheses. We first show that the influence of small amounts of contamination in the data on the test decision can be very large. Secondly we build a robust test statistic by using the results on robust parametric tests available in the literature and show that the level of...

In this paper, we describe a technique for integrating heterogeneous information systems using concept bases. A concept base is build on top of each system to integrate, in order to semantically enrich its description. Each concept is described at three different levels: terminological definition, formal characterization, and representation in the underlying system. The different...

This report proposes to employ messengers, initially developed in the context of communication protocols, as a fundamental component of the architecture of distributed operating systems. Current microkernels offer non-local services which require the collaboration of neighboring machines or special servers and are implemented using special protocols. These protocols are hard-wired...

Drawing on recent work concerning the statistical robustness of inequality statistics we examine the sensitivity of poverty indices to data contamination using the concept of the influence function. We show that poverty and inequality indices have fundamentally different robustness properties, and demonstrate that an important commonly used subclass of poverty measures will be robust...
