A neutral metapopulation model of biodiversity in river networks

In this paper, we develop a stochastic, discrete, structured meta population model to explore the dynamics and patterns of biodiversity of riparian vegetation. In the model, individual plants spread along a branched network via directional dispersal and un ...

Interior penalty finite element approximation of Navier-Stokes equations and application to free surface flows

Christoph Winkelmann

In the present work, we investigate mathematical and numerical aspects of interior penalty finite element methods for free surface flows. We consider the incompressible Navier-Stokes equations with variable density and viscosity, combined with a front capt ...

Reverse transfer of nanostencil patterns using intermediate sacrificial layer and lift-off process

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

We propose a new process by which patterns produced by nanostencil lithography can be reversed, so that the final pattern on the substrate has the same contrast (filled or empty) as that of the stencil. In this process, the stencil pattern is first formed ...

Reverse nanostencil lithography using dual pattern transfer

Jürgen Brugger, Marc Antonius Friedrich van den Boogaart, Oscar Vazquez Mena

Nanostencil lithography is considered a promising emerging nanopatterning method due to its simple process flow, low cost, little restriction on materials, and high compatibility with organic or biological surfaces. The principle of shadow mask deposition ...

Emerging Nanopatterning Methods based on MEMS Technology

Jürgen Brugger

The development of nanosystems and nano-devices demands for patterning methods in the nanoscale. To bring them to the market, there is a need for fast, low-cost nanopatterning methods. In addition, an increased flexibility is important for the engineering ...

Dynamic Stencil Lithography

Recent developments are going towards miniaturized devices and structures. Besides advanced photolithography techniques, complementary patterning methods are evolving. Among them is the nanostencil technique. This technique is about defining patterns under ...

Novel composite coded pattern for small angle measurement using imaging method

Sai Siva Gorthi

A novel approach for measurement of small rotation angles using imaging method is proposed and demonstrated. A plane mirror placed on a precision rotating table is used for imaging the newly designed composite coded pattern. The imaged patterns are capture ...

Applications of Specification and Design Languages for SoCs Selected papers from FDL'05

Alain Vachoux

Applications of Specification and Design Languages for SoCs includes a selection of the best contributions to the Forum on Specification and Design Languages held in 2005 (FDL'05). Since its inception in 1998, FDL has established itself as the premier Euro ...

Information-theoretic framework for unsupervised activity classification

Frédéric Kaplan

This article presents a mathematical framework based on information theory to compare multivariate sensory streams. Central to this approach is the notion of configuration: a set of distances between information sources, statistically evaluated for a given ...

An all-in-one solution to geometric and photometric calibration

Pascal Fua, Vincent Lepetit, Julien Pilet, Pascal Lagger, Andreas Geiger

We propose a fully automated approach to calibrating multiple cameras whose fields of view may not all overlap. Our technique only requires waving an arbitrary textured planar pattern in front of the cameras, which is the only manual intervention that is r ...

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.
