Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Verification of Software Network Functions with No Verification Expertise

Arseniy Zaostrovnykh

Software network functions (NFs), such as a network address translator, load balancer, or proxy, promise to bring flexibility and rapid innovation to computer networks and to reduce operational costs. However, continuous updates and flexibility typically c ...

From Timed Component-Based Systems to Time-Triggered Implementations: A Correct-by-Design Approach

In hard real-time embedded systems, design and specification methods and their associated tools must allow development of temporally deterministic systems to ensure their safety. To achieve this goal, we are specifically interested in methodologies based o ...

Animation-Based Service Specification, Verification and Validation

Biljana Bajic-Bizumic

[Context] With the expansion of services and service science, service systems have become an important abstraction for the service revolution. Service is defined as the application of resources (including competences, skills, and knowledge) to make changes ...

Synthesizing robust systems

Barbara Jobstmann

Systems should not only be correct but also robust in the sense that they behave reasonably in unexpected situations. This article addresses synthesis of robust reactive systems from temporal specifications. Existing methods allow arbitrary behavior if ass ...

Contracts for Real-Time, Safety Critical Systems

Chandrakana Nandi

Verifying real-time systems goes beyond the verification of functional properties: it also requires the checking of real-time properties. This makes traditional contract-frameworks partially inept for checking real-time programs. This is a major problem be ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Ghislain Roquier, Richard Thavot, Abdallah Alaaeldin Abdelaziz Elguindy

The recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementat ...

Analog property checkers: a DDR2 case study

Dejan Nickovic

The formal specification component of verification can be exported to simulation through the idea of property checkers. The essence of this approach is the automatic construction of an observer from the specification in the form of a program that can be in ...

Formal semantics for refinement verification of entreprise models

Irina Rychkova

In this dissertation we investigate how Business/IT alignment in enterprise models can be enhanced by using a software engineering stepwise refinement paradigm. To have an IT system that supports an enterprise and meets the enterprise business needs, manag ...

Declarative Specification and Alignment Verification of Services in ITIL

Gil Regev, Alain Wegmann, Irina Rychkova

IT organizations that wish to implement the best practices recommended by the IT Infrastructure Library (ITIL) need to specify the level of service provided to their customers. The implemented service needs to comply with this specification. We propose a m ...

Refinement Propagation. Towards Automated Construction of Visual Specifications.

Alain Wegmann, Irina Rychkova

Creation and transformation of visual specifications is driven by modeler’s design decisions. After a design decision has been made, the modeler needs to adjust the specification to maintain its correctness. The number of adjustments might make the design ...
