Dynamic collapse analyses of a 4-story steel building frame modeled by solid elements are performed using the E-Simulator, which is a parallel finite element analysis software package for civil and building structures. Code verification, calculation verification, and validation of the numerical codes (V&V) are conducted by comparing the results obtained by the E-Simulator, those obtained by a beam element analysis code, and the experimental results obtained by the 3-D full-scale earthquake testing facility, the E-Defense at NIED. The seismic response analyses under 60% or 100% of the JR Takatori seismic wave of the 1995 Hyogoken-Nanbu earthquake are performed. The shear forces and interstory drift angles of the 1st story obtained by the E-Simulator simulation and the E-Defense full-scale test have good agreement. Both response of the whole frame and local deformation due to plastic buckling are simulated in the analysis using the E-Simulator.

The efficient and fast processing of path planning algorithms based on stencil codes is a great challenge. On the one hand, these iterative approaches are advantageous because of their regular processing pattern and the characteristic to avoid problems of other path planning methods, like local minima in potential field algorithms. On the other hand, they are computational- and data-intensive because of their high number of required iterations. By comparing several algorithms based on stencil codes, we found one of the fastest and most efficient path planners for realization on FPGAs, Akers's wavefront planner. A processing of 33 maps per second with a resolution of 1024×1024 is possible on a midsize Virtex-5 FPGA achieved through a column-based processing scheme combined with an efficient internal data storage.

To maximize training effects in free weight exercises, people need to remember repetitions of each type of exercises, which is tedious and difficult. Recognizing exercises type and counting automatically can overcome this problem, and multiple accelerometers were used in the existing exercises recognition. This paper presents a new recognition method based on one triaxial accelerometer, in which a filtered acceleration data stream is divided into time series with unequal length for peak analysis instead of conventional fixed length window. Based on this time series, Dynamic Time Warping (DTW) is deployed to recognize weight exercise types. 3D Euclidean distance and Itakura parallelogram constraint region are used to improve recognition performance. A reference template is set up for each class based on many examples instead of one in the conventional way. The proposed procedures are compared with other popular methods with both the user-dependent protocol and the userindependent protocol. Results show that proposed approach is feasible and can achieve good performance. © Springer-Verlag Berlin Heidelberg 2013.

International Conference on Reconfigurable Computing and FPGAs (ReConFig)

Industrial image processing tasks, especially in the domain of optical metrology, are becoming more and more complex. While in the recent years standard PC components were sufficient to fulfill the requirements, special architectures have to be used to build up high speed image processing systems today. For example for adaptive optical systems in large scale telescopes, the latency between capturing an image and steering the mirrors is critical for the quality of the resulting images. Commonly, the applied image processing algorithms consist of several tasks with different granularities and complexities. Therefore, we combined the advantages of multicore CPUs, GPUs, and FPGAs to build up a heterogeneous image processing pipeline for adaptive optical systems. Each used architecture is well-suited to solve a particular task efficiently. With the developed pipeline it is possible to achieve a high throughput and to reduce the latency of the whole steering system significantly.

IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing Workshops (ISORCW)

作者： Michael Schmidt Marc Reichenbach Dietmar Fey Department Computer Science Chair of Computer Architecture Friedrich-Alexander-Universitat Erlangen-Nuremberg Erlangen-Nuremberg Germany

The efficient realization of self-organizing systems based on 2D stencil code applications, like our developed Marching Pixel algorithms, is a great challenge. They are data-intensive and also computational-intensive, because often a high number of iterations is required. FPGAs are predestined for the realization of these algorithms. They are very flexible, allow a scalable parallel processing and have a moderate power consumption, even in high-performance versions. Therefore, FPGAs are highly qualified to make these applications also real-time capable. Our goal was to implement an efficient parameterizable buffering and parallel processing scheme for such operations in FPGAs, to process them as fast as possible. We developed a generic VHDL template which allows a scalable parallelization and pipelining of 2D stencil code applications in relation to application and hardware constraints.

IEEE International Conference on Utility and Cloud Computing (UCC)

作者： Marc Mosch Hartmut Schweizer Stephan Gross Alexander Schill Department of Computer Science Institute of Systems Architecture Chair of Computer Networks Technische Universität Dresden Dresden Germany

Virtualization and broadband Internet connections enabled what is known today under the term cloud. Benefits like scalability and cost reduction by pay per use agreements are accompanied by potential harm to the users data. Since existing cloud solutions can be considered synonymous with unknown locations and potentially hostile environments security protection objectives can not be guaranteed. Motivated by cloud's potential we propose a way to get rid of this drawback. We present work in progress of an approach that enables users to benefit from cloud computing and retain data sovereignty by federating the users own resources. More precisely we present initial protocol design thoughts for this federation and an extension of the OCCI specification for the flexible description of own and foreign services.

Background After menopause the risk of osteoporosis increases significantly caused by subsequent bone loss that can be modified by environmental factors, such as properly balanced diet and physical activity. Objectives The purpose of this study was to evaluate the dietary and lifestyle factors that impact bone health in the group postmenopausal women (without diagnosed osteopenia or osteoporosis) Methods Anthropometric data were collected from 509 postmenopausal women that were characterised by different values of BMI: 133 had proper body mass (BMI < 25 kg/m 2 ; B1), 111 were overweight (BMI 25,0-29,9 kg/m 2 ; B2) and 265 obese (BMI>30 kg/m 2 ; B3). Body composition were measured by bioimpedance method (BODYSTAT 1500 device). Waist to Hip Ratio (WHR) was used to characterised different body fat distributions (visceral and gynoidal). Nutritional data were collected using the seven-days 24-hour dietary recall questionnaire. The differences between groups with different values of BMI and WHR were estimated using ANOVA Kruskal-Wallis's and U-Manna-Whitney's test. Results The average age of postmenopausal women was about 60 years. Low physical activity of women was assumed (only 11% of them exercised regularly). The waist circumference increased with the value of BMI, so overweight and obese women were characterised by visceral deposition of fat tissue. The energy value of analysed groups were similar and achieved nearly 2000 kcal, however the daily food rations were improperly balanced. An amount of protein was higher than 15% of energy intake and increased with the value of BMI. Consumption of animal protein was nearly twice bigger than plant one. Fat intake exceeded 33% of energy value in all analysed groups. In consequence the carbohydrates intake were low and did not exceeded 52%. Sodium intake range from 2,15g (B1) to 2,33g (B2) and potassium consumption vary from 3,501g (B1) to 3,641g (B2). Calcium intake was low and decreased with the value of BMI (B1 738mg to B3

As interactive systems become increasingly entwined with architecture, and spaces become able to detect the presence of individuals, we argue that the control of visibility as a temporary personal state should be considered in the design of public spaces. This workshop will provide the opportunity for participants to engage hands-on with a computer vision tracking system (OpenCV) and explore how low-cost materials and tools can be used to render people invisible in monitored public space. We invite researchers and practitioners from the fields of art, design, HCI, architecture and social science to consider strategies for managing personal visibility and how these relate to design and the use of technologies. The intention of the workshop is not to produce implementable designs. Instead we prefer to make speculative design scenarios that might act as future inspiration or critique. By focusing on practical strategies for managing personal visibility we hope to extend designers thinking of presence in public space beyond the purely physical to include digital representations of inhabitation that are processed and archived remotely. © 2012 Authors.

This work presents a novel approach for human action recognition based on the combination of computer vision techniques and common-sense knowledge and reasoning capabilities. The emphasis of this work is on how common sense has to be leveraged to a vision-based human action recognition so that nonsensical errors can be amended at the understanding stage. The proposed framework is to be deployed in a realistic environment in which humans behave rationally, that is, motivated by an aim or a reason. © 2012 Springer-Verlag.
