Exploiting the color of Brownian motion for high-frequency microrheology of Newtonian fluids

László Forró, Flavio Maurizio Mor, Sylvia Jeney

Einstein's stochastic description of the random movement of small objects in a fluid, i.e. Brownian motion, reveals to be quite different, when observed on short timescales. The limitations of Einstein's theory with respect to particle inertia and hydrodyn ...

Electrochemical Model of Solid Oxide Fuel Cell for Simulation at the Stack Scale I. Calibration Procedure on Experimental Data

Daniel Favrat, Jan Van Herle, Stefan Diethelm, Zacharie Wuillemin, Arata Nakajo

Lifetime prediction and improvement of solid oxide fuel cell (SOFC) devices require a reliable electrochemical model that supports the implementation of degradation phenomena. This study comprises two parts. This Part I describes the calibration of an elec ...

Comparison of farmers’ mental models of the present and the future: A case study of pesticide use

Claudia Rebeca Binder Signer

Farmers in developing countries will in the future be confronted with major changes. The ability to cope with these challenges rests on their capability to relate future problems to current behavior. Our approach investigates this capability and consists i ...

Towards an improved understanding of farmers' behaviour: The integrative agent-centred (IAC) framework

Claudia Rebeca Binder Signer

An effective approach to research on farmers' behaviour is based on: i) an explicit and well-motivated behavioural theory; ii) an integrative approach; and iii) understanding feedback processes and dynamics. While current approaches may effectively tackle ...

Multichannel Sequence Analysis Applied To Social Science Data

Philipp Bucher

Applications of optimal matching analysis in the social sciences are typically based on sequences of specific social statuses that model the residential, family, or occupational trajectories of individuals. Despite the broadly recognized interdependence of ...

Testate amoebae ecology and a local transfer function from a peatland in western Poland

Mariusz Lamentowicz

In Chlebowo mire (Wielkopolska region), we investigated testate amoebae in relation to ten environmental parameters in the semi-natural floating vegetation of flooded peat workings. The measured parameters included: depth to water table (DWT), ground-water ...

Semantic Representation of Individualized Reaction Movements for Virtual Human

Daniel Thalmann, Frédéric Vexo, Alejandra Garcia Rojas Martinez

Virtual Human (VH) creation aims to provide virtual characters with realistic behavior, which implies endowing them with autonomy in an inhabited virtual environment. Autonomous behavior consists in interacting with users or the environment and reacting to ...

Construire à distance

Habib Sayah

Through a case study, this research aims at contributing to the historic understanding of the international architecture after the Second World War. It is based on the monographic analysis of the projects realised by the Geneva agency Addor & Julliard in L ...

Interactive Low-Dimensional Human Motion Synthesis by Combining Motion Models and PIK

Daniel Thalmann, Ronan Boulic

This paper explores the issue of interactive low-dimensional human motion synthesis. We compare the performances of two motion models, i.e. Principal Components Analysis (PCA) or Probabilistic PCA (PPCA), for solving a constrained optimization problem with ...

On the influence of elevated strike objects on directly measured and indirectly estimated lightning currents

Marcos Rubinstein

The knowledge of lightning current parameters comes essentially from direct measurements obtained using instrumented towers or triggered lightning, and from measurements of lightning electromagnetic fields assuming empirical or theoretical relations betwee ...
