A new concept of microelectromechanical system based thermoelectric power generator (TPG) with unique heat dissipation path is investigated in this study. By using solder based wafer bonding technology, the authors can bond three pieces of wafers to form vacuum packaged TPG. According to the finite element method and analytical modeling results, the output power per area of device is derived as 68.6μW∕cm2 for temperature difference of about 6°C between two ends of thermocouple junctions. It shows that the proposed device concept is an effective and low cost approach to enhance the output voltage.

Simplicialization of digital volumes in 26-adjacency: Application to topological analysis

引用

Pattern Recognition and Image Analysis 2009年第2期19卷 231-238页

作者： Mari, J. -L. Real, P. Information and System Science Laboratory (LSIS) Computer Graphics Dept. (“Image and Models” Team) University of Marseille II ESIL Marseille cedex 9 France Dpto. de Matemática Aplicada I Escuela Técnica Superior de Ingeniería Informatica Universidad de Sevilla Sevilla Spain

In this paper, we introduce a simple and original algorithm to compute a three-dimensional simplicial complex topologically equivalent to a 3D digital object V, according to the 26-adjacency. The use of this adjacency generates issues like auto-intersecting triangles that unnecessarily increase the dimensionality of the associated simplicial complex. To avoid these problems, we present an approach based on a modified Delaunay tetrahedralization of the digital object, that preserves its topological characteristics. Considering the resulting complex as an input in algebraic-topological format (fixing a ground ring for the coefficients), we develop propositions regardless of the adjacency considered. These potential applications are related to topological analysis like thinning, homology computation, topological characterization and control. Moreover, our technique is susceptible to be extended to higher dimensions.

Journal of Networks 2009年第6期4卷 445-457页

This paper describes a cooperative MANET protocol dedicated to intelligent transport systems, named CIVIC (Communication Inter Véhicule Intelligente et Coopérative). The CIVIC protocol is an auto-configuration inter-vehicle communication protocol, which supports adhoc and infrastructure networks, contains reactive and proactive routing components, and adapts different wireless standards. It is a context-aware protocol reacting to vehicle status, road traffic, and geographic environment. It supports location-based communication. To improve the accuracy of GPS, it integrates a localization solution called LCD-GPS (Low Cost Differential GPS). It has been implemented and experimented on the LiveNode sensor developed by our lab. At the end of this paper, an application project MobiPlus is introduced. © 2009 ACADEMY PUBLISHER.

14th Eurographics Symposium on Virtual Environments, EGVE 2008

This paper describes the design of the 'BAT' (Bonn Articulated Tracker) visual tracking framework. This system allows the easy implementation of real-time, multi-camera motion tracking that can be distributed (also in multithreaded sense) across several computing nodes (or CPU cores). The system in itself does not realize any specific tracking system, but manages a meta-algorithm flow between processing blocks. An actual tracking implementation is realized by specifying the processing blocks through plugins. Depending on the plugins supplied, 'BAT' is capable to instantiate a wide-variety of systems ranging from object-detection methods to model-based deformable object tracking based on time-coherence, allowing also for hybrid algorithms. Being a "meta dataflow system", 'BAT' also naturally facilitates sensor fusion. Moreover, it can be used as a testbed to compare and evaluate different kind of tracking algorithms or algorithm substeps. © The Eurographics Association 2008.

This paper describes a cooperative MANET protocol dedicated to intelligent transportation systems and its new experiment results in mobile scenarios. The protocol is named CIVIC (Communication Inter Veacutehicule Intelligente et Coopeacuterative). It is an auto-configuration inter-vehicle communication protocol, which supports ad-hoc and infrastructure networks, contains reactive and proactive routing components, and adapts different wireless standards. It is also a location-based and context-aware protocol reacting to vehicle status, road traffic, and geographic environment. The CIVIC protocol has been implemented on the LiveNode sensor developed by our laboratory. The new experiments of CIVIC protocol are carried out on PAVIN platform (Plate-forme d'Auvergne pour Veacutehicules Intelligents) supported by the TIMS (Technologies de l'Information de la Mobiliteacute et de la Sucircreteacute) research federation. These experiments demonstrate the feasibility and reliability of CIVIC in mobility scenarios. In addition, an application project named MobiPlus will be introduced.

Free-Form Deformation with Rational DMS-Spline Volumes

引用

Journal of computer science & Technology 2008年第5期23卷 862-873页

作者：徐岗汪国昭陈小雕 Institute of Computer Graphics and Image Processing Zhejiang University Department of Mathematics Zhejiang University College of Computer Science Hangzhou Dianzi University INRIA Nancy France

In this paper, we propose a novel free-form deformation （FFD） technique, RDMS-FFD （Rational DMS-FFD）, based on rational DMS-spline volumes. RDMS-FFD inherits some good properties of rational DMS-spline volumes and combines more deformation techniques than previous FFD methods in a consistent framework, such as local deformation, control lattice of arbitrary topology, smooth deformation, multiresolution deformation and direct manipulation of deformation. We first introduce the rational DMS-spline volume by directly generalizing the previous results related to DMS-splines. How to generate a tetrahedral domain that approximates the shape of the object to be deformed is also introduced in this paper. Unlike the traditional FFD techniques, we manipulate the vertices of the tetrahedral domain to achieve deformation results. Our system demonstrates that RDMS-FFD is powerful and intuitive in geometric modeling.

Accurate techniques for simulating soft biological tissue deformation are an increasingly valuable tool in many areas of biomechanical analysis and medical image computing. To model the morphology and the material response of human articular cartilage a phenomenological and patient-specific simulation approach incorporating the collagen fibre fabric is proposed. We then demonstrate a unique combination of ultra-high field Diffusion Tensor Magnetic Resonance Imaging (17.6T DT-MRI) and a novel numerical approach incorporating the empirical data to predict the collagen fibre fabric deformation for an indentation experiment. © 2009 WILEY-VCH Verlag GmbH & Co.
