Strabon: A Semantic Geospatial DBMS
We present Strabon, a new RDF store that supports the state of the art semantic geospatial query languages stSPARQL and GeoSPARQL. To illustrate the expressive power offered by these query languages and their implementation in Strabon, we concentrate on th ...
Springer Berlin Heidelberg2012Offset And Drift Analysis Of The Hall Effect Sensors. The Geometrical Parameters Influence
Maher Kayal, Jean-Michel Sallese, Maria-Alexandra Paun
Several Hall sensor configurations have been integrated in CMOS 0.35 mu m technology and analyzed in terms of offset at room temperature and offset drift. We searched for the best geometry that would minimize the offset and its corresponding drift. The tar ...
Inst Materials Physics2012Design and Implementation of Multi-camera Systems Distributed over a Spherical Geometry
Alexandre Schmid, Yusuf Leblebici, Hossein Afshari, Kerem Seyid
The current trend in constructing high-end computing systems consists of parallelizing large numbers of processors. A similar trend is observed in digital imaging where multiple camera inputs are utilized to obtain multiple images of a scene and thus enhan ...
2012Three-dimensional granular model of semi-solid metallic alloys undergoing solidification: Fluid flow and localization of feeding
Michel Rappaz, Jean-Marie Drezet, André Phillion, Meisam Sistaninia
A three-dimensional (3-D) granular model which simulates fluid flow within solidifying alloys with a globular microstructure, such as that found in grain refined Al alloys, is presented. The model geometry within a representative volume element (RVE) consi ...
Elsevier2012Metastable de Sitter vacua in N=2 to N=1 truncated supergravity
Claudio Scrucca, Paul Smyth, Francesca Catino
We study the possibility of achieving metastable de Sitter vacua in general N=2 to N=1 truncated supergravities without vector multiplets, and compare with the situations arising in N=2 theories with only hypermultiplets and N=1 theories with only chiral m ...
Springer2012A Spherical Multi-camera System with Real-time Omnidirectional Video Acquisition Capability
Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari
A multi-camera system inspired from the visual system of flying insects is introduced which is referred to as the Panoptic camera. In the Panoptic system each camera is mounted over a hemispherical geometry and has its own vision of surrounding and distinc ...
Institute of Electrical and Electronics Engineers2012Geometry-Induced Rigidity in Nonspherical Pressurized Elastic Shells
Pedro Miguel Nunes Pereira de Almeida Reis
We present results from an experimental investigation of the indentation of nonspherical pressurized elastic shells with a positive Gauss curvature. A predictive framework is proposed that rationalizes the dependence of the local rigidity of an indented sh ...
American Physical Society2012Applications of the Transfinite Map for Parametrized Domain Decomposition
A big challenge in the last few years is to perform simulations of cardiovascular systems. Since it would be too computational expensive and complicated to simulate an entire blood circuit, an idea is to use a Domain Decomposition (DD) technique and to spl ...
2012On the Static and Dynamic Behavior of the Germanium Electron-Hole Bilayer Tunnel FET
Mihai Adrian Ionescu, Luca De Michielis, Livio Lattanzio, Nilay Dagtekin
Tunnel FETs (TFETs) are being intensively investigated for their potential in achieving subthermal switching slopes and extremely low leakage currents. Recently, a promising concept has been proposed: the electron-hole bilayer TFET (EHBTFET), which exploit ...
Ieee-Inst Electrical Electronics Engineers Inc2012Scalar geometry and masses in Calabi-Yau string models
Claudio Scrucca, Daniel Farquet
We study the geometry of the scalar manifolds emerging in the no-scale sector of Kahler moduli and matter fields in generic Calabi-Yau string compactifications, and describe its implications on scalar masses. We consider both heterotic and orientifold mode ...
