We present a framework for formal reasoning about the behaviour of distributed programs implementing open distributed systems (ODSs). the framework is based on the following key ingredients: A specification language b...

We present an algebra for programming the itineraries of mobile agents. the algebra contains operators for modelling sequential, parallel, nondeterministic, and conditional mobility behaviour. Iterative behaviour is a...

In this paper, a new framework for rapid system design and implementation for fuzzy systems is proposed. the given system specification is separated into two components: A conceptual specification and a parameter spec...

the Coq and ProPre systems show the automated termination of a recursive function by first constructing a tree associated withthe specification of the function which satisfies a notion of terminal property and then v...

computing devices are clearly proliferating in a variety of domains ranging from controlling household appliances, to the cockpits of aircraft. thus, there is an ever increasing demand for cheap and compact computers intended to perform a few functions, extremely well. Historically, customization has been the answer to this need. However, customization unfortunately implies very high costs—the exacerbated costs limit the scope of proliferation of course. To redress this and thus enable the extraordinary growth-potential of these emerging domains— loosely referred to as embedded systems here—current research in computing is revisiting established and stable technologies ranging from (high-level) programming languages at the software end of the spectrum, to gate-level design and synthesis at the hardware end. A theme that seems to be emerging, is to provide the future application developer withthe advantages of customization, at costs approaching currently mass-produced commercial-off-the-shelf (COTS) software and hardware. thus, hardware is increasingly being viewed as a flexible fabric, amenable to low-cost customization based on the application developer’s needs and preferences. A goal of this talk is to outline the “point-technologies” that are being innovated to help realize this vision.
We investigate Orex, a temporal logic for specifying open systems. Path properties in Orex are expressed using ω-regular expressions, while similar logics for open systems, such as ATL* of Alur et al., use LTL for th...

A temporal logic of causality (TLC) was introduced by Alur, Penczek and Peled in [1]. It is basically a linear time temporal logic interpreted over Mazurkiewicz traces which allows quantification over causal chains. T...

Verification of formal specifications for multimedia systems, with time taken into consideration, is still a subject of much research. Estelle, an internationally standardised Formal Description Technique (FDT) based ...

Ant Colony Optimization (ACO) is a paradigm that em- ploys a set of cooperating agents to solve functions or obtain good so- lutions for combinatorial optimization problems. It has previously been applied to the TSP a...

Pure functional programming languages have been proposed as a vehicle to describe, simulate and manipulate circuit specifications. We propose an extension to Haskell to solve a standard problem when manipulating data ...
