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.

Innovative design and multi-objective optimization of hybrid reverse osmosis and multi-stage flash desalination plants

François Maréchal, François Vince

The selection of an hybrid MSF/RO desalination plant depends on many factors, such as capital costs, electricity consumption, water conversion rate and local requirements. In order to provide the necessary information for the decision process, stand-alone ...

The Plenacoustic Function and its Sampling

Martin Vetterli, Luciano Sbaiz, Thibaut Ajdler

The spatialization of the sound field in a room is studied, in particular the evolution of room impulse responses as a function of their spatial positions. It was observed that the multidimensional spectrum of the solution of the wave equation has an almos ...

The Plenacoustic Function and its Sampling

Martin Vetterli, Luciano Sbaiz, Thibaut Ajdler

We study the spatialization of the sound field in a room, in particular the evolution of room impulse responses as a function of their spatial positions. We observe that the multidimensional spectrum of the solution of the wave equation has an almost bandl ...

Interactive three-dimensional reconstruction and weathering simulations on buildings

Stéphane Gobron

Architectural sites suffers from weathering effects such as liquid sedimentation, lampblack or pollution deposit, moss growing or longterm erosion. Displaying their impact on present buildings could help deciders to plan relevant actions for preserving the ...

Jurdzinski-ing Rabin and Streett

In this paper we give a recursive fixpoint characterization of the winning regions in Rabin and Streett games. We use this characterization in two ways. First, we introduce direct Rabin and Streett ranking that are a sound and complete way to characterize ...

Sound propagation over irregular terrain with complex meteorological effects using the parabolic equation model

François Aballéa

Sound impact of road and railway infrastructures are more and more severely regulated by European laws: acceptable thresholds in emission and reception are decreasing. This implies to develop propagation models able to take many phenomena into account at t ...

Conducting a virtual orchestra

Daniel Thalmann, Frédéric Vexo, Sébastien Schertenleib

The virtual orchestra is a multimodal system architecture based on complex 3D sound environment processing and a compact user interface. The system architecture supports high-performance sound content for VR (virtual reality) applications, and the user con ...

Fractal additive synthesis

Pietro Polotti

Musical and audio signals in general form a major part of the large amount of data exchange taking place in our information-based society. Transmission of high quality audio signals through narrow-band channels, such as the Internet, requires refined metho ...

The Plenacoustic Function, Sampling and Reconstruction

Martin Vetterli, Thibaut Ajdler

In the present paper, we study the spatialization of the soundfield in a room, in particular the evolution of room impulse responses as function of their spatial positions. The presented technique allows us to completely characterize the sound field in any ...
