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.

How Fast Can a Very Robust Read Be?

Rachid Guerraoui, Marko Vukolic

This paper studies the time complexity of reading unauthenticated data from a distributed storage made of a set of failure-prone base objects. More specifically, we consider the abstraction of a robust read/write storage that provides wait-free access to u ...

Inner Classes and Virtual Types

Vincent Cremet, Philippe Altherr

This paper studies the interplay between inner classes and virtual types. The combination of these two concepts can be observed in object-oriented languages like Beta or Scala. This study is based on a calculus of classes and objects composed of a very lim ...

Refactoring OCL Annotated UML Class Diagrams

Slavisa Markovic

Refactoring of UML class diagrams is an emerging research topic and heavily inspired by refactoring of program code written in object-oriented implementation languages. Current class diagram refactoring techniques concentrate on the diagrammatic part but n ...

Comparing Algorithms for Reconstructing Digital Off-Axis Fresnel Holograms

Michaël Unser

Three-dimensional information about an object, such as its depth, may be captured and stored digitally in a single, two-dimensional, real-valued hologram acquired in an off-axis geometry. Digital reconstruction of the hologram permits the quantitative retr ...

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 ...

Role Composition in Requirements Engineering:the Method and Prototyping Tool

Alain Wegmann, Gleb Skobeltsyn, Pavel Balabko

Using multiple contexts improves model understandability and contributes to solving a scalability problem. In our work, we introduce a modeling method called Systemic Enterprise Architecture Methodology (SEAM) that considers systems to be designed in diffe ...

Meta-model for Object-Oriented Hierarchical Systems

Alain Wegmann, Lam Son Lê

In enterprise architecture, the goal is to integrate business resources and IT resources in order to improve an enterprises competitiveness. In an enterprise architecture project, the development team constructs a hierarchical model that represents the ent ...

A Variational Model for Object Segmentation Using Boundary Information, Statistical Shape Prior and the Mumford-Shah Functional

Jean-Philippe Thiran, Pierre Vandergheynst, Xavier Bresson

In this paper, we propose a variational model to segment an object belonging to a given scale space using the active contour method, a geometric shape prior and the Mumford-Shah functional. We define an energy functional composed by three complementary ter ...

Matching pursuit-based shape description and recognition in active contours

François Mendels

This thesis is dedicated to the study of a new framework linking image segmentation and shape recognition processes in the image processing domain. Image segmentation process aims at separating an image into homogenous regions, the homogeneity measure depe ...
