10th international conference on advances in Web-Based Learning, ICWL 2011

作者： Tammets, Kairit Pata, Kai Laanpere, Mart Tomberg, Vladimir Gašević, Dragan Siadaty, Melody Centre for Educational Technology Institute of Informatics Tallinn University Narva road 25 Tallinn 10120 Estonia Athabasca University Simon Fraser University Canada

For supporting technology-enhanced in-service teacher accreditation for professional competences, this case study in Estonian context investigates the applicability of an organizational knowledge-management (KM) model extended by the principles of self-regulated learning. the survey findings revealed the existing state, open challenges, and potential barriers of supporting teachers' lifelong learning activities with the new model. An activity scenario and a set of software services supporting the harmonization of teachers' accreditation with the model were developed via a participatory design process with the teachers. the evaluation indicated that organizational, intra- and inter-personal scaffolds embedded in services were used concurrently in each accreditation activity. © 2011 Springer-Verlag.

international conference on Collaborative Computing: Networking, Applications and Worksharing (CollaborateCom)

作者： Panayiotis Neophytou Panos K. Chrysanthis Alexandros Labrinidis Advanced Data Management Technologies Laboratory Department of Computer Science University of Pittsburgh USA

Data streams have become pervasive and data production rates are increasing exponentially, driven by advances in technology, for example the proliferation of sensors, smart phones, and their applications. this fact effectuates an unprecedented opportunity to build real-time monitoring and analytics applications, which when used collaboratively and interactively, will provide insights to every aspect of our environment, both in the business and scientific domains. In our previous work, we have identified the need for workflow management systems which are capable of orchestrating the processing of multiple heterogeneous data streams, while enabling their users to interact collaboratively with the workflows in real time. In this paper, we describe CONFLuEnCE (CONtinuous workFLow ExeCution Engine), which is an implementation of our continuous workflow model. CONFLuEnCE is built on top of Kepler, an existing workflow management system, by fusing stream semantics and stream processing methods as another computational domain. Furthermore, we explicate our experiences in designing and implementing real-life business and scientific continuous workflow monitoring applications, which attest to the ease of use and applicability of our system.

this chapter describes a reconfigurable computing architecture based on clusters of regular matrices of fine-grain dynamically reconfigurable cells using double-gate carbon nanotube field effect transistors (DG-CNTFET), which exhibit ambivalence (p-type or n-type behaviour depending on the backgate voltage). Hierarchical function mapping methods suitable for the cluster of matrices structure have been devised, and various benchmark circuits mapped to the architecture. this work shows how circuit and architecture designers can work with emerging technology concepts to examine its suitability for use in computing platforms. © IFIP international Federation for Information Processing 2011.

2nd international conference on Ambient Systems, Networks and Technologies, ANT-2011 and 8th international conference on Mobile Web Information Systems, MobiWIS 2011

In the power industry various companies have a crucial responsibility of sustaining infrastructure for electricity service. Maintenance and repair of electrical devices out in the field is potentially dangerous and sometimes complicated in nature. Effective and safe fieldwork requires clear and accurate communication between fieldworkers repairing and maintaining devices outdoors and operators monitoring and controlling the power grid in a control room. Operators and fieldworkers have to synchronize their activities for maintaining steady electricity service. Current Information and Communication technology (ICT) support for fieldwork consist of mobile phones, mobile software applications and workforce management systems, but much of the necessary communication is still conducted orally over the phone. We propose ambient communication support that improves communication between operators and fieldworkers by digitalizing and automating trivial messaging. the concept is based on mobile navigation and work order management application, image-processing techniques for wearable sensor based activity recognition methods. In theory we can eliminate three of eight logical steps in a typical work scenario. We present work-in-progress in form of preliminary prototypes and discuss the technological advances needed to make the concept real. © 2011 Published by Elsevier Ltd.

Demonstration of an all-diode pumped soft x-ray laser and other advances in table-top soft x-ray lasers 12th

12th international conference on X-Ray Lasers, 2010

We report the first demonstration of an all-diode-pumped soft x-ray laser system. Lasing was achieved in the λ = 18.9 nm line of Ni-like Mo ions pumping with a diode-pumped cryo-cooled Yb:YAG chirped-pulse-amplification laser system that generates 1 J pulses of 8.5 ps duration. Driver lasers pump by diodes opens the possibility to develop a new generation more compact soft x-ray lasers operating at significantly increased repetition rates for applications. In a separate development we have demonstrated a gain-saturated table-top λ=10.9 nm laser operating at 1 Hz repetition rate with an average power of 1 μW in the 4d1S0→4p1P1 transition of nickel-like Te and observed lasing at 8.8 nm in nickel-like La in plasmas exited by a Ti:sapphire laser. Utilizing the same pump laser we obtained laser pulse energies of up to 10 μJ and an average power of 20 μW in the 13.9 nm line of Ni-like Ag. In a third set of experiments we characterized the beam properties of an injection-seeded soft x-ray laser based on the amplification of high harmonic pulses in a solid-target plasma soft x-ray laser amplifier. Injection-seeding is shown to dramatically improve the far-field laser beam profile and reduce the beam divergence. Measurements and 2-dimensional simulations for a 13.9 nm nickel-like Ag amplifier show that the amplified beam divergence depends strongly on the seed divergence, and can therefore be tailored by selecting it. © Canopus Academic Publishing Limited 2011.

Ridgelet transform has gained its popularity due to its capability in dealing with line singularities effectively at several levels of detail. this paper presents a novel approach for describing shapes based on Ridgelet transform. We propose a new implementation of the transformation called Invariant Generalised Ridgelet transform, which is invariant to rotation, scaling, and translation (RST) as well as able to handle images of arbitrary size. We introduce the implementation of Ridgelet transform on the ellipse containing the shape and the normalisation of the Radon transform. the 1D Wavelet transform is then applied to the Radon slices. In order to extract rotation invariant feature, Fourier transform is implemented in the Ridgelet domain. We test the new method on a standard MPEG-7 CE-1 B dataset in terms of precision and recall. From the experiments, it is shown that retrieval effectiveness has been significantly improved by 83.12%.

there is a widely recognized need for rigorous quantitative performance assessment in many topics within computer vision, which leads to the adoption of appropriate figures of merit, image datasets, and benchmarks (e.g., in the form of ground truth). In this paper, we present a quantitative evaluation of different approaches for the salient regions detection task using different public image datasets and figures of merit. We briefly describe the suitability of the preselected datasets and the candidate figures of merit - recall, precision, F1 and area of overlap - in the context of the current task. Finally, the results of experiments using the salient region detection algorithms and different datasets are presented and commented. From the obtained data, we suggest one most adequate dataset and discuss why the current figures of merit, although acceptable and suitable for the task, are not ideal.

A chatbot is a program which can chat in natural language, on a topic built into the chatbot's internal knowledge model. Many chatbots exist, with different knowledge-bases programmed by the chatbot builders. We have built a system to convert a website text (corpus) to a chatbot knowledge-base format. In this paper the chatbot is used as a question answer interface, where TRE09 QA track is used to automatically retrain the chatbot knowledge-base. Evaluation shows promising results, 2/3 of generated answers were correct. We aim to see how to improve the algorithm for building the knowledge base before comparing this tool with other natural language interfaces.
