This Letter presents a measurement of the W+W− production cross section in s=7 TeV pp collisions by the ATLAS experiment, using 34 pb−1 of integrated luminosity produced by the Large Hadron Collider at CERN. Selecting events with two isolated leptons, each either an electron or a muon, 8 candidate events are observed with an expected background of 1.7±0.6 events. The measured cross section is 41−16+20(stat)±5(syst)±1(lumi) pb, which is consistent with the standard model prediction of 44±3 pb calculated at next-to-leading order in QCD.

Sensor networks are a sensing, computing and communication infrastructure that are able to observe and respond to phenomena in the natural environment and in our physical and cyber infrastructure. The sensors themselves can range from small passive micro-sensors to larger scale, controllable weather-sensing platforms. In this work, we investigate how the sensor network performs in the case when the sink node moves. We consider as a metrics for evaluation goodput and Routing Efficiency (RE). We compare the simulation results when the sink node is mobile and stationary considering lattice topology using AODV protocol. The simulation results have shown that for the case of mobile sink, the goodput is better when the number of nodes is 16. However, when the number of nodes are 100 and 256, the goodput of mobile sink is worse than stationary sink when the values T r is larger than 1pps. For both stationary and mobile sinks, the RE increases with the increase of number of sensor nodes, but the RE of mobile sink is better than the stationary sink.

A search for a heavy standard model Higgs boson decaying via H→ZZ→ℓ+ℓ−νν¯, where ℓ=e, μ, is presented. It is based on proton-proton collision data at s=7 TeV, collected by the ATLAS experiment at the LHC in the first half of 2011 and corresponding to an integrated luminosity of 1.04 fb−1. The data are compared to the expected standard model backgrounds. The data and the background expectations are found to be in agreement and upper limits are placed on the Higgs boson production cross section over the entire mass window considered; in particular, the production of a standard model Higgs boson is excluded in the region 340

Accurate identification of lesion borders is an important task in the analysis of dermoscopy images since the extraction of skin lesion borders provides important cues for accurate diagnosis. Snakes have been used for segmenting a variety of medical imagery including dermoscopy, however, due to the compromise of internal and external energy forces they can lead to under- or over-segmentation problems. In this paper, we introduce a mean shift based gradient vector flow (GVF) snake algorithm that drives the internal/external energies towards the correct direction. The proposed segmentation method incorporates a mean shift operation within the standard GVF cost function. Experimental results on a large set of diverse dermoscopy images demonstrate that the presented method accurately determines skin lesion borders in dermoscopy images.

Feedback delays are inherent attributes of distributed control systems that usually cause unfavorable effect on the stability of the controlled process. Modelling of such systems is essential for traceable controller synthesis. In this paper we apply the TP Model Transformation to derive a polytopic representation of an LPV model where the time-delay is considered as parameter. The method is introduced via a single degree of freedom impedance model with feedback delay. The resulted model is validated by simulation.

Advanced visualization technologies are gaining major importance to interpret, present and manipulate high dimensional biomedical data. Since new health technologies are constantly increasing in complexity, adequate information processing is required for diagnostics, therapy planning and treatment. The combination of advanced visualization resources and biomedical grid infrastructures is a promising approach to build dynamic and scalable problem solving environments for such tasks. Visualization then becomes the main issue in system-user interaction, and is therefore a crucial factor in the usefulness of the complete system for the domain researchers. In this paper, two remote visualization approaches to utilize the capabilities of such an environment are presented and evaluated. Evaluation criteria are performance, usability, adaptivity and functionality. Both, an open source and a commercial solution are considered. While the proprietary software shows better performance, the open source solution offers the advantage for seamless grid integration.

Part of the activities of the ICT EU Network of Excellence "Building the future Optical Network in Europe" (BONE) project is the development of the European Roadmap on Optical Networking in the context of the "Network of the Future". This paper presents a summary of the views of the BONE consortium as they were developed in the framework of the Roadmap activity. The methodology followed in the development of the BONE Roadmap was firstly to identify and analyse the status of broadband access penetration as well as the availability of specific network and IT technologies in various European countries. The data collected were then processed and translated into the traffic volume (distributed across different European countries) that a Pan- European network would need to support. This information is then used as the basis of a WDM optical network dimensioning exercise performed with the aim of identifying the scale of the required optical network. In addition, based on estimations regarding the evolution of broadband access technologies and the degree of broadband penetration and network services and applications, extrapolations regarding the growth of traffic to be supported by the European Network of the Future were made in a systematic manner. These were also used to dimension and understand the requirements of the European Network of the Future. This paper presents the relevant results and also provides a discussion on the BONE consortium views on the Network of the Future from an architectural and technology perspective and an outlook of the relevant key research challenges and possible solutions. © 2010 IEEE.

Petriu Stefan Preitl János Fodor Daniela Bărbulescu Department of Automation and Applied Informatics Polytechnic University of Timisoara Timisoara Romania “Politehnica” University of Timisoara Timisoara RO Romania Faculty of Computer Science Aurel Vlaicu University of Arad Arad Romania Faculty of Computer Science Complex Universitar Arad RO Romania University of Ottawa School of Information Technology and Engineering Ottawa ON Canada Óbuda University Institute of Intelligent Engineering Systems Budapest Hungary

This paper suggests a new stability analysis approach dedicated to a class of fuzzy control systems controlling multi input-multi output (MIMO) nonlinear processes by means of Takagi-Sugeno fuzzy logic controllers. The approach is based on LaSalle's global invariant set theorem, and an original stability theorem offers sufficient stability conditions. The applicability and efficiency of the theoretical results are illustrated by a MIMO case study dealing with the fuzzy control of a spherical three tank system.

In this paper, the e-JIKEI Network project, a project for creating community safety with present day technology, is reviewed. With the e-JIKEI Network, each individual watches around his/her house using cameras as his/her eyes, a computer as his/her brain, and software. For privacy protection, we propose the e-JIKEI with Privacy Protection, in which people who own and manage images (the owner) and people who have the right to view the images (the viewer) are separated by the encryption of the images. In order to evaluate our concept, social experiments have been performed. The present status and future prospects have been discussed in detail.
