SANDS: Structured Algebraic Net Development System
Graph Chatbot
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.
In contrast to beta-testing, formal verification can guarantee correctness of a program against a specification. Two basic verification techniques are theorem proving and model checking. Both have strengths and weaknesses. Theorem proving is powerful, but ...
Language-centric methodologies, triggered by the success of Domain Specific Languages, rely on precise specifications of modeling languages. While the definition of the abstract syntax is standardized by the 4-layer metamodel architecture of the OMG, most ...
Software engineering always cares to provide solutions for building applications as close as possible to what they should be, according to the requirements and the final users needs. Systems behavior simulation is a very common application to virtually rep ...
Engineering of software-intensive systems is concerned with the creation and evolution of systems that shall exhibit desired properties in their execution as well as development environment. In this context, the motivation of this thesis, derived from curr ...
Visual modeling languages propose specialized diagrams to represent behaviour and concepts necessary to specify IT systems. As a result, to understand a specification, the modeller needs to analyze these two types of diagrams and, often, additional stateme ...
Decision support systems can be used to manage systems. Managed systems are described by system specifications. System specification notations, such as UML, often separate in different diagrams the static specification and the dynamic specification of the ...
This paper studies implementations of concurrent objects that exploit the absence of step contention. These implementations use only reads and writes when a process is running solo. The other processes might be busy with other objects, swapped-out, failed, ...
Both ethnographers and engineers deal with contextual and situational complexity in human behavior. For engineers, this complexity creates challenges in designing systems to support humans that are useful and predictable across a wide range of contexts bec ...
This paper summarises the approach taken to develop an open architecture full tokamak discharge simulator - DINA-CH based on the DINA code and implemented under graphical programming control using Matlab-SIMULINK. The evolution path and present status are ...
The ease of compiling malicious code from source code in higher programming languages has increased the volatility of malicious programs: The first appearance of a new worm in the wild is usually followed by modified versions in quick succession. As demons ...
