Multi-Camera People Tracking with a Probabilistic Occupancy Map

Pascal Fua, François Fleuret, Jérôme Berclaz

Given two to four synchronized video streams taken at eye level and from different angles, we show that we can effectively combine a generative model with dynamic programming to accurately follow up to six individuals across thousands of frames in spite of ...

Production and properties of substituted LaFeO3-perovskite tubular membranes for partial oxidation of methane to syngas

Jan Van Herle, Stefan Diethelm, Defne Bayraktar

Tubular membranes of La0.6Ca0.4Fe0.75Co0.25O3−δ and La0.5Sr0.5Fe1−yTiyO3−δ (y = 0, 0.2) for the application of partial oxidation of methane to syngas were produced by thermoplastic extrusion and investigated by oxygen permeation measurements. The optimum c ...

Bone-cement interface of the glenoid component: stress analysis for varying cement thickness

Alexandre Terrier, Alain Farron, Philippe Büchler

BACKGROUND: Although shoulder arthroplasty is an accepted treatment for osteoarthritis, loosening of the glenoid component, which mainly occurs at the bone-cement interface, remains a major concern. Presently, the mechanical effect of the cement mantel thi ...

Titanium oxides and silicates as high-kappa dielectrics: A first-principles investigation

Alfredo Pasquarello

Using density functional theory, we investigate the structural, vibrational, and dielectric properties of titanium oxides and silicates, which have attracted considerable attention in the framework of the quest for alternative high-K materials. For the oxi ...

Experimental investigation of the mechanical behaviour and structure of the bovine periodontal ligament

Colin Sanctuary

One of the key problems in dental biomechanics is the prediction of tooth mobility under functional loads. Understanding tooth displacement due to load is becoming more important as new solutions in dental restorations, prosthodontics and orthodontic treat ...

Conductivity of Mn and Ni-doped stabilized zirconia electrolyte

Jan Van Herle

We develop SOFC based on a NiO–YSZ anode support, a thin YSZ layer (5–10 micron) and a LaSrMnO3 cathode. Mn and Ni can dissolve into thin zirconia during high temperature fabrication. On cells, we consistently measured higher ohmic losses than expected fro ...

Nitriding of tetragonal zirconia in a high current d.c. plasma source

Christoph Hollenstein, Thierry Delachaux

Surface nitriding of tetragonal zirconia (t-ZrO2) has been performed with the aim of combining the optical properties of zirconium nitride (ZrN) with the hardness and toughening properties of tetragonal zirconia. A high current d.c. arc plasma source has b ...

Deformable tissue parameterized by properties of real biological tissue

Daniel Thalmann, Ronan Boulic, Anderson Maciel

Realistic mechanical models of biological soft tissues are a key issue to allow the implementation of reliable systems to aid on orthopedic diagnosis and surgery planning. We are working to develop a computerized soft tissues model for biotissues based on ...

First-principles study of dynamical and dielectric properties of tetragonal zirconia

Alfredo Pasquarello

Using the variational density-functional perturbation theory, we investigate the dynamical and dielectric properties of tetragonal zirconia (t-ZrO2). We obtain the phonon frequencies at the center of the Brillouin zone, the Born effective charge tensors, a ...

Powder blasting for three-dimensional microstructuring of glass

Martinus Gijs, Abdeljalil Sayah

We report on powder blasting as a promising technology for the three-dimensional structuring of brittle materials. We investigate the basic parameters of this process, which is based on the erosion of a masked substrate by a high-velocity eroding powder be ...
