We have developed a veriication framework that combines deductive reasoning, general purpose decision procedures, and domain-speciic reasoning. This paper describes this framework and presents a case study in which we veriied a SRT divider circuit. Our proof starts with a high-level description of the SRT algorithm on rational numbers. We veriied the correctness of the algorithm. With a sequenc...

Recently, the notion of an array-based system has been introduced as an abstraction of infinite state sys-tems (such as mutual exclusion protocols or sorting programs) which allows for model checking of invariant(safety) and recurrence (liveness) properties by Satisfiability Modulo Theories (SMT) techniques. Unfortu-nately, the use of quantified first-order formulae to describe sets...

We present a simple tool that enables the computer to read subtitles of movies and TV shows aloud. The tool extracts information from subtitle files, which can be freely downloaded or extracted from a DVD, and reads the text aloud through a speech synthesizer. The target audience is people who have trouble reading subtitles while watching a movie, for example people with visual impairments and ...

An overview is given of a light weight Object Oriented OO multi database system named AMOS II Object Oriented multi database queries and views can be de ned where external data sources of di erent kinds are translated through AMOS II and integrated through its OOmediation primitives Through its multi database facilities many distributed AMOS II systems can inter operate Since most data reside i...

Incisional hernias remain one of the most common surgical complications with a long-term incidence of 10-20%. Increasing evidence of impaired wound healing in these patients supports routine use of an open prefascial, retromuscular mesh repair. Basic pathophysiologic principles dictate that for a successful long-term outcome and prevention of recurrence, a wide overlap underneath healthy tissue...

MOTIVATION Due to the increasing number of molecular biological databases and the exponential growth of their contents, database integration is an important topic of research in bioinformatics. Existing approaches in this area have in common that considerable efforts are needed to provide integrated access to heterogeneous data sources. RESULTS This article describes the LIMBO architecture as...

We present the design and prototype implementation of the scheduling component in ArTCoP (architecture transparent control of parallelism), a novel run-time environment (RTE) for parallel execution of high-level languages. A key feature of ArTCoP is its support for deep process and memory hierarchies, shown in the scheduler by supporting light-weight threads. To realise a system with easily exc...

A simple and natural explanation for the dynamics and morphology of the Local Group Dwarf Spheroidal galaxies, Draco (Dra) and Ursa Minor (UMi), is that they are weakly unbound stellar systems with no significant dark matter component. A gentle, but persistent, Milky Way (MW) tide has left them in their current kinematic and morphological state. This short paper reviews the parametric tidal int...

The component software technology is a promising trend for rapid software development. However, one of the problems of software engineering is still inherited, which is the high cost of program verification. Moreover, not just the component, but also the composition of components is a subject for verification. In the direction of component software free-trade market, verification concerns becom...

The demand for applications involving Wireless Sensor Network (WSN) or RFID systems is increasing. The sensor in a WSN and RFID tag/reader in a RFID system are called resource constrained devices because these devices have limited processing power, memory size and energy supply. The information transmitted among these low resource devices must be protected from unauthorized access using specifi...
