Frugal Mobile Objects

Rachid Guerraoui, Maxime Monod, Benoît Garbinato, Jesper Honig Spring

This paper presents a computing model for resource-limited mobile devices. The originality of the model lies in the integration of a strongly-typed event-based communication paradigm with abstractions for frugal control, assuming a small footprint runtime. ...

Non-deterministic Constructs in OCL -- What does any() Mean

The Object Constraint Language (OCL) offers so-called non-deterministic constructs which are often only poorly understood even by OCL experts. They are widely ignored in the OCL literature, their semantics given in the official language description of OCL ...

Generation of object-oriented programs from CO-OPN specifications

Stanislav Chachkov

The execution of formal specifications is important for verification, validation and animation purposes. This thesis describes transformation of CO-OPN specifications in executable code. The original goal of this transformation was validation by prototypin ...

Implementing a State Space Analyzer for Synchronous Java

Claude Petitpierre

In this paper we present a toolset aimed at the analysis of programs written in Java and a new kind of active objects. The toolset detects if the program contains deadlocks and may provide a CCS description along with a labeled transition system of the pro ...

Deadlock Detector for Synchronous Java.

Claude Petitpierre

In this paper, we present a work that aims to detect deadlocks in the programs written in the Synchronous Java language (sJava). It is based on an extension to a model-checking framework Bogor that allows the verification of concurrent Java programs. The d ...

Modelling the phase synchronization in systems of two and three coupled oscillators

Martin Hasler

We obtain regions of synchronization of two and three globally coupled oscillators, and describe the main mechanisms and bifurcaations through which the system synchronization is lost ...

Modelling a Secure, Mobile and Transactional System with CO-OPN

Stanislav Chachkov

Modelling complex concurrent systems is often difficult and error-prone, in particular when new concepts coming from advanced practical applications are considered. These new application domains include dynamicity, mobility, security, and localization depe ...

Towards the Formal Integration of Two Upcoming Standards: IEC61970 and IEC61850

Otto Preiss, Christian Frei, Tatjana Kostic

AbstractThe constant demand for a better integration of utility applications and systems provokes the question on the compatibility of standards that were, and still are, developed for these individual utility disciplines. This paper discusses the need for ...
