Covariant formulation of relativistic mechanics

Accretion disks surrounding compact objects, and other environmental factors, deviate satellites from geodetic motion. Unfortunately, setting up the equations of motion for such relativistic trajectories is not as simple as in Newtonian mechanics. The prin ...

One-step solution to local tie vector determination at co-located GNSS/VLBI sites

Jean-Philippe Lucien Montillet

The local tie vector, which connects the different space geodetic techniques at a co-located site, plays an important role in the realization of the International Terrestrial Reference Frame (ITRF). This paper presents a new method to determine the tie vec ...

Drift Reduction for Inertial Sensor Based Orientation and Position Estimation in the Presence of High Dynamic Variability During Competitive Skiing and Daily-Life Walking

Benedikt Fasel

Nowadays inertial sensors are extensively used for gait analysis. They can be used to perform temporal event detection (i.e. step detection) and to estimate the orientation of the feet and other body segments to determine walking speed and distance. Usuall ...

Adapting tilt corrections and the governing flow equations for steep, fully three-dimensional, mountainous terrain

Wolf Hendrik Huwald, Marc Parlange, Holly Jayne Oldroyd, Eric Richard Pardyjak

In recent studies of atmospheric turbulent surface exchange in complex terrain, questions arise concerning velocity-sensor tilt corrections and the governing flow equations for coordinate systems aligned with steep slopes. The standard planar-fit method, a ...

Interactive real-time physics: An intuitive approach to form-finding and structural analysis for design and education

Gennaro Senatore

Real-time physics simulation has been extensively used in computer games, but its potential has yet to be fully realized in design and education. We present an interactive 3D physics engine with a wide variety of applications. In common with traditional FE ...

Bacterial communities associated with chloroethene–contaminated aquifers present both geographical isolation and strong correlations to local environmental variables

Christof Holliger, Pierre Rossi, Noam Shani

Numerous industries and facilities have been using chlorinated ethenes (CEs) as non-flammable solvents during manufacturing. Massive usage, careless handling and storage, spills and leakages made them one of the most frequent aquifer contaminants. CEs are ...

Learning the structure of image collections with latent aspect models

Florent Monay Michaud

The approach to indexing an image collection depends on the type of data to organize. Satellite images are likely to be searched with latitude and longitude coordinates, medical images are often searched with an image example that serves as a visual query, ...
