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.
The basis of the discrete element method is to model masses interacting with each other through different forces and constraints. On each mass, the second law of Newton is applied to obtain a differential equation. From this equation and boundary condition ...
In 1791, one year after the first US Patent Act, the French ‘Loi relative aux découvertes utiles’ sought to revolutionize the Ancien Régime’s privileges of invention, turning them into new patents or ‘brevets d’invention’. Not only did the law recast ci-de ...
If we study the evolution of the urban space in Switzerland we must notice the high importance assigned by different urban actors to aesthetic questions. In a sense, the subjective realm of the aesthetic has proved to be able to generate conditions that le ...
We investigate whether corporations and their executives react to an exogenous change in passive institutional ownership and alter their corporate governance structure. We find that exogenous increases in passive ownership lead to increases in CEO power an ...
We use a strategic household survey to study the sensitivity of intended homeownership decisions to financing constraints. We find that the average stated likelihood of buying a home is strongly sensitive to the size of the required down payment, which we ...
We study a regularisation of Coulomb's friction law on the propagation of local slip at an interface between a deformable and a rigid solid. This regularisation, which was proposed based on experimental observations, smooths the effect of a sudden jump in ...
Despite the vast diversity of sizes and shapes of living organisms, life's organization across scales exhibits remarkable commonalities, most notably through the approximate validity of Kleiber's law, the power law scaling of metabolic rates with the mass ...
Scaling exponents for the conductivity and stiffness of replicated microcellular materials exceed commonly predicted values of 1 and 2. We show here that this is caused by the fact that, in replicated microcellular materials, the solid architecture varies ...
In recent work on open, privacy-preserving, accountable surveillance, we have proposed the use of cryptographic protocols that enable law-enforcement and intelligence agencies to obtain actionable information about targeted users of mass-communication syst ...
When governments act as owners of state-owned enterprises (SOEs), they are both principal and agent at the same time. The literature on steering SOEs has mainly focused on the government as the principal that must control SOEs. However, the government is a ...
