Evidential reasoning provides a framework for managing beliefs in an environment where information may be un certain, imprecise, and occasionally inaccurate. Image processing and pattern recognition applications provide excellent examples of systems where the outputs are often uncertain and inaccurate. In real-time image processing applications a sequence of images is collected and classi fied over time. During operation of the system, it may experience a variety of environmental conditions that may cause great variability in the robustness of the classifica tion decision. This variability may be due to changes in object orientation, illumination, or occlusion. A process ing framework is required to manage the classification decisions made in this environment in order to reduce the classification error. We propose a framework based on the Dempster Shafer theory of evidential reasoning to process a real-time sequence of image classification results. We demonstrate the performance of our proposed sequential classification processing in the application of a real-time vision system for smart automotive airbags. Our proposed approach leads to nearly a 20% increase over the original classification accuracy of the system, and provides a 10 15% improvement over traditional classifier combination methods.

In this article we describe a computational architecture called MC2 that brings together a set of tools that contribute to the knowledge management process by allowing for the creation and maintenance of organizational memory. To achieve this end, the approach taken by MC2 is aimed at establishing favorable conditions for interaction between the personnel within an organization as well as with the system itself. Another main goal of MC2 is to heighten personnel awareness as to the importance of their participation in the process, thereby creating an organizational culture of continuous learning. In particular, we describe a tool for automatic knowledge discovery extracted from organizational databases and the manner in which this tool is integrated with the MC2 environment. Through the use of this tool, organizational development is fostered by disseminating knowledge in such a way so as to be transparent to its originators, thus, it requires no additional effort on their part above and beyond those already accomplished in their day-to-day activities.

A new device that divides the thermal-diffusion column into two passages by inserting a permeable-barrier resulting in improving the degree of separation of heavy water was investigated analytically. The theoretical model and analytical solution were obtained by using the variable separation with an orthogonal expansion technique in terms of power series. The theoretical predictions were represented graphically with the aspect ratio and channel thickness ratio parameters and compared with those obtained in the Clusius-Dickel column of the same working dimensions. Considerable improvement on heavy water enrichment was obtainable by employing such double-flow devices with inserting a permeable barrier, instead of using the Clusius-Dickel thermal-diffusion column. The effects of the permeable barrier locations as well as the aspect ratio, and channel thickness ratio on the separation efficiency enhancement of heavy water in double-flows thermal-diffusion columns have been also delineated.

In this paper we present a number of new structures to enhance the design of adaptive self-assessment in the already existing engineering approaches, concerning specifications and standards for re-usable learning design. The structures are designed having in mind the self assessment modeler of AWAIT (Author for a Web-based Adaptive Intelligent Tutor), and we try to study the opportunities afforded by the IMS Learning Design (IMS LD) specification in order to make AWAIT’s self assessment design available as re-usable learning material. AWAIT is a no IMS LD aware software, designed as an authoring tool for a typical adaptive educational hypermedia system called WADIES. WADIES offers navigation support adapted to the students’ individual needs and incorporates a novel self-assessment agent encouraging the students to actively construct their knowledge through the incorporation of multiple self assessing strategies. This means that the student is offered the opportunity to answer to exercises of the same thematic topic from a number of different perspectives until the self-assessment goal is reached. Our approach for re-usable learning design of adaptive self-assessment activities is based on the research at the domain of Educational Adaptive Hypermedia (EAH) and the IMS LD specification.

Computationally-enriched crafts are activities that blend the advantages of computational media with the affective, social, and cognitive affordances of children's crafts. In this paper, we describe a design application, Popup Workshop, whose purpose is to introduce children to the craft (and engineering discipline) of pop-up design in paper. We describe the fundamental ideas behind computational crafts in general, present our application in its current implementation and offer a scenario for its use, explore the particular ways in which pop-up design serves as fertile ground for integrating computation and tangible design, and discuss our early pilot-tests with elementary school children, as well as ongoing and related work.

We describe the fundamental ideas behind computational crafts in general, present our application in its current implementation and offer a scenario for its use, explore the particular ways in which pop-up design serves as fertile ground for integrating computation and tangible design, and discuss our early pilot-tests with elementary school children, as well as ongoing and related work.

On-line music distributors are hesitant to release music in MP3 format, as this standard is an open-format and piracy of copyrighted music may be facilitated. Instead, they pre fer to use proprietary formats and proprietary DRM sys tems. Users do not like this approach, as it limits the e music flexibility without giving any benefit. In this paper we propose an alternative that enables vendors to securely distribute open-formats and users to have benefits from us ing legal media copies. In particular, we propose to se curely enrich and distribute MP3 files with multimedia con tents and to adopt security mechanisms transparent to users to protect vendors' rights. No restriction is set on the MP3 audio play out, but only a legitimate MP3 owner can use both audio and multimedia contents; a non legitimate MP3 owner can still enjoy the audio portion, but no more than that. This way, users are stimulated to avoid music piracy.

The proliferation of line connected electronic equipment using sinle phase rectifiers to process the ac input power has resulted in two concerns: the poor powerfactor of the typical rectifier and the harmonic content of its ac line current. Poor powerfactor translates into poor utilisation of the available current carrying capacity of the ac distributed system. High harmonic content in the line current frequently causes mutual interference among line connected equipment, especially on a 'weak' system and degrades the Power Quality (PQ). Hence, this paper presents the design and simulation of a novel single stage, single switch, Boost cell type AC-DC converter with active Power Factor Correction (PFC) to enrich power quality. Average current-mode control technique has been used for active current shaping in the proposed system which has the advantages of fast current tracking and constant switching frequency. A comparison is made for AC-DC converter with and without PFC circuitry with respect to imput power factor and total harmonic distortion (THD) of the input current. The simulation result validates the effectiveness of the proposed control scheme. The proposed active power factor corrected rectifier finds applications in low-power, low-cost system and also it enhances the power quality.

Poor powerfactor translates into poor utilisation of the available current carrying capacity of the ac distributed system. High harmonic content in the line current frequently causes mutual interference among line connected equipment, especially on a 'weak' system and degrades the Power Quality (PQ). Hence, this paper presents the design and simulation of a novel single stage, single switch, Boost cell type AC-DC converter with active Power Factor Correction (PFC) to enrich power quality. Average current-mode control technique has been used for active current shaping in the proposed system which has the advantages of fast current tracking and constant switching frequency. A comparison is made for AC-DC converter with and without PFC circuitry with respect to imput power factor and total harmonic distortion (THD) of the input current. The simulation result validates the effectiveness of the proposed control scheme. The proposed active power factor corrected rectifier finds applications in low-power, low-cost system and also it enhances the power quality.
