In the near future mobile robots accomplishing such tasks as delivery of goods, assistance for handicapped people and surveillance will become increasingly available. The aim of this paper is to show the disparity that exists at present in modeling buildings for the purposes of two domains: Architecture, Engineering & Construction (AEC) and Mobile Robotics (MR). Digital product and process models developed in the AEC-domain give the user a comprehensive insight into the components and functions of the building but they neglect the needs of mobile robot operating autonomously inside the building. On the other hand, researchers in the MR-domain seem to be unaware of the results achieved in the AEC area. During the last decades the main effort in MR was devoted to the autonomous navigation. This resulted in efficient and robust procedures of acquiring floor maps from sensor readings. Further progress requires the robot to understand semantics of the surrounding world. Based on our previous research in the graph-oriented support of the AEC-design, we propose a digital model of the building that will enable the robot to recognize the functionality of particular spaces, to transform CAD-based floor plans into graphs reflecting topology and function of the building, to plan the execution of tasks posed by the human operator and to navigate inside the building. © 2009 ASCE.

The Brillouin light-scattering technique has been applied to study collective spin waves in a dense array of dipolarly coupled Ni80Fe20 stripes of alternating widths, during the magnetization reversal process. Both the saturated “ferromagnetic” state, where the magnetizations of wide and narrow stripes are parallel, and the “antiferromagnetic” state, characterized by an antiparallel alignment of the static magnetization in adjacent stripes, have been analyzed. The experimental data provide strong evidence of sustained collective excitations in the form of Bloch waves with permitted and forbidden magnonic energy bands. The measured frequencies as a function of the exchanged wave vector have been satisfactorily reproduced by numerical simulations which enabled us to calculate the spatial profiles of the Bloch waves, showing that some of the modes are preferentially localized in either the wide or the narrow stripes. We estimated the expected light-scattering cross section for each mode at different magnetic ground states, achieving a good agreement with the measured intensities. The alternating-width stripes system studied here represents a one-dimensional artificial magnonic crystal with a complex base and can be considered as a model system for reprogrammable dynamical response, where the band structure of collective spin waves can be tailored by changing the applied magnetic field.

A search for diphoton events with large missing transverse energy is presented. The data were collected with the ATLAS detector in proton-proton collisions at s=7 TeV at the CERN Large Hadron Collider and correspond to an integrated luminosity of 3.1 pb−1. No excess of such events is observed above the standard model background prediction. In the context of a specific model with one universal extra dimension with compactification radius R and gravity-induced decays, values of 1/R<729 GeV are excluded at 95% C. L., providing the most sensitive limit on this model to date.

Latin American Test Workshop, LATW

作者： Marc Messing Andreas Glowatz Friedrich Hapke Rolf Drechsler Institute of Computer Science University of Brethemen Bremen Germany Mentor Graphics Development (Deutschland) GmbH Hamburg Germany

Automatic Test Pattern Generation (ATPG) is one of the core algorithms in testing of digital circuits and systems. Based on a given fault model a list of all faults to be tested, i.e. the fault list, is being created. For each fault in this list, one test pattern is generated (this pattern may cover other faults). Thereby, the order of the faults is crucial. In industrial ATPG, typically a simple list is used as fault list until today. In this work, we introduce a two-dimensional fault list and different strategies to order this list. The target is to reduce the number of generated patterns. The techniques are implemented in an industrial ATPG-framework. They are evaluated on industrial circuits. The results are discussed and a general purpose strategy is given.

Dynamic contrast-enhanced image data (perfusion data) are used to characterize regional tissue perfusion. Perfusion data consist of a sequence of images, acquired after a contrast agent bolus is applied. Perfusion data are used for diagnostic purposes in oncology, ischemic stroke assessment or myocardial ischemia. The diagnostic evaluation of perfusion data is challenging, since the data is complex and exhibits various artifacts, e.g., motion artifacts. We provide an overview on existing methods to analyze, and visualize CT and MR perfusion data. The integrated visualization of several 2D parameter maps, the 3D visualization of parameter volumes and exploration techniques are discussed. An essential aspect in the diagnosis of perfusion data is the correlation between perfusion data and derived time-intensity curves as well as with other image data, in particular with high resolution morphologic image data. We discuss visualization support with respect to the three major application areas: ischemic stroke diagnosis, breast tumor diagnosis and the diagnosis of coronary heart disease. © 2006 IEEE.

With the upcoming features of Web 2.0 current eLearning solutions, mostly characterized by single user and centered data-download, change and develop further. The traditional paradigm of classroom teaching and learning is broadened towards sharing experiences and knowledge in word-wide social communities. Furthermore, knowledge capturing in ambient environments gains more importance and the use of mobile devices has created rich and exciting learning opportunities. These aspects characterize the socalled eLearning 2.0. Different aspects of this paradigm shift are presented in this paper and the European Community supported UNITE project as an application case is offered. The technical aspects of the platform development cycle are provided and its enhanced eKnowledge repositories are addressed. The UNITE system implementation in the setting of one of the European-wide network of schools is presented as an iterative four-stage-process, the achieved results are discussed and future work is proposed. © 2009 Academy Publisher.

In this paper, we propose a color images steganography. Firstly, because modification of pixel of image edges is less sensitive to human eye, the edge or texture in one plane is detected by Sobel edge detection operator and the largest certain number of gradients are selected as embedding positions. Secondly, because of strong relevance in gradient among R, G, and B planes, the corresponding LSB (Least Significant Bit) of pixel values to hide the secret data in other planes is modified. Finally, combine the stego-planes and restore the color image. Furthermore, multi-times embedding can be adapted to obtain high data capacity. Experimental results show that stego-images keep good quality and high capacity. For example, there is no noticeable degradation after three times hiding process, the average PSNR is about 45db and data capacity is 6.3bpp. The method also can extract the secret data accurately.

Measurements of charged particle distributions, sensitive to the underlying event, have been performed with the ATLAS detector at the LHC. The measurements are based on data collected using a minimum-bias trigger to select proton-proton collisions at center-of-mass energies of 900 GeV and 7 TeV. The “underlying event” is defined as those aspects of a hadronic interaction attributed not to the hard scattering process, but rather to the accompanying interactions of the rest of the proton. Three regions are defined in azimuthal angle with respect to the highest transverse momentum charged particle in the event, such that the region transverse to the dominant momentum-flow is most sensitive to the underlying event. In each of these regions, distributions of the charged particle multiplicity, transverse momentum density, and average pT are measured. The data show generally higher underlying event activity than that predicted by Monte Carlo models tuned to pre-LHC data.

A measurement of the cross section for the inclusive production of isolated prompt photons in pp collisions at a center-of-mass energy s=7 TeV is presented. The measurement covers the pseudorapidity ranges |ηγ|<1.37 and 1.52≤|ηγ|<1.81 in the transverse energy range 15≤ETγ<100 GeV. The results are based on an integrated luminosity of 880 nb−1, collected with the ATLAS detector at the Large Hadron Collider. Photon candidates are identified by combining information from the calorimeters and from the inner tracker. Residual background in the selected sample is estimated from data based on the observed distribution of the transverse isolation energy in a narrow cone around the photon candidate. The results are compared to predictions from next-to-leading-order perturbative QCD calculations.
