Title: Assessing ICT User Groups
Authors: Benjamin Weiss, Ina Wechsung, Stefanie Marquardt
Abstract: A questionnaire to assess attitude towards information and communication technology (ICT) and experience with it is developed and evaluated. With 30 items user attributes are collected on six factors. With this questionnaire, individual users can be clustered in accordance with an existing ICT taxonomy. A revised version is proposed after the validation of the first questionnaire. This screening instrument is meant to complement existing methods of assessing competency with technology. Furthermore, the possibility to classify users within the ICT taxonomy provides additional means to analyze data from interaction experiments and to screen prospective participants for usability tests and scientific experiments.

Title: Bricolage: Example-Based Retargeting for Web Design
Authors: Ranjitha Kumar Jerry O Talton Salman Ahmad Scott R Klemmer
Abstract: The Web provides a corpus of design examples unparalleled in human history. However, leveraging existing designs to produce new pages is often difficult. This paper introduces the Bricolage algorithm for transferring design and content between Web pages. Bricolage employs a novel, structured-prediction technique that learns to create coherent mappings between pages by training on human-generated exemplars. The produced mappings are then used to automatically transfer the content from one page into the style and layout of an-other. We show that Bricolage can learn to accurately repro-duce human page mappings, and that it provides a general, efficient, and automatic technique for retargeting content between a variety of real Web pages.

Title: Low Power VLSI Implementation of Adaptive Noise Canceller Based on LeastMean Square Algorithm
Authors: Vakulabharanam Ramakrishna, Tipparti Anil Kumar
Abstract: This paper presents VLSI implementation of adaptive noise canceller based on least mean square algorithm. First, the adaptive parameters are obtained by simulating noise canceller on MATLAB. Simulink model of adaptive noise canceller was developed and the noise is suppressed to a much larger extent in recovering the original signal. The data such as input and output signals, desired signal, step size factor and coefficients of adaptive filter was processed by FPGA. Finally, the functions of field programmable gate array -based system structure for adaptive noise canceller based on LMS algorithm are synthesized, simulated, and implemented on XilinxXC3s200 field programmable gate array using Xilinx ISE tool. The research results show that it is feasible to implement and use adaptive least mean square filter based adaptive noise canceller design which consumed a low power of 0.156W at29.1° C in a single field programmable gate array chip.

Title: The Application of Coal Cleaning Detection System based on Embedded Real-time Image Processing
Authors: Qian Mu ,Jixian Dong
Abstract: This paper introduces a high-speed image processing of embedded systems based on FPGA and DSP collaboration used in coal preparation detection technology. The system uses a modular design, including a real-time image acquisition module, DSP image processing module, and peripheral interface module. The image processing required doing the following arithmetic operations, including image smoothing to enhance, edge detection, region segmentation, gray-scale analysis, pattern recognition. After completion of the above algorithm, the system determines the image feature of coal and gangue, particularly their gray scale values and the center of gravity. By analysis of the characteristics of the image, the system identifies the gangue. The image processing is conducive to the follow-up to discharge refuse treatment .

Title: A Secure Authentication Protocol among Mobile Phone and Wireless Sensor Networks
Authors: Ndibanje Bruce, Hoon Jae Lee
Abstract: The interaction between mobile phone and wireless sensor networks has increased these days due to the WSN emergence and its ubiquitous nature. Through cellular network, a user can access gateway of wireless sensor networks and gets the data. This paper proposes a secure authentication protocol where a user is strongly verified before accessing the data. The secure authentication proposed protocol provides many security principles to the users for instance user, mutual authentication, and secure session key establishment. Furthermore, security analysis shows .that the proposed protocol possesses many advantages against popular attacks, and achieves better efficiency at low computation cost.
