We propose an algorithm for finding the optimal decoder activation order in a system with more than two concatenated codes. Optimality is defined as the order that yields convergence using the lowest computational complexity, guided by the extrinsic information transfer (EXIT) charts of the component codes. We also describe how the convergence threshold for the system can be visualized by combining several multi-dimensional EXIT charts into one two-dimensional EXIT chart.

In spite of advances in educational techonology, most Web-based computer science courses rely on costly pre-made learning materials. By shifting the emphasis to peer-to-peer learning and other student-centred learning principles, more meaningful learning process can be accomplished, without preparing stand-alone Web-courses. A course applying these principles is presented along with a tool built for the purpose. The tool offers the possibility to build a joint information pool and publish new work while constructing knowledge by collaborative annotation of the information or published work. According to our experince, transparency in the learning process is also well-accepted and viewed beneficial by the students.

This paper presents an action selection framework based on an assemblage of self-organizing neural networks called Cooperative Extended Kohonen Maps. This framework encapsulates two features that significantly enhance a robot's action selection capability: self-organization in the continuous state and action spaces to provide smooth, efficient and fine motion control;action selection via the cooperation and competition of Extended Kohonen Maps to achieve more complex motion tasks. Qualitative tests demonstrate the capability of our action selection method for both single-and multi-robot motion tasks.

Many systematic approaches have been studied to represent documents. One of the approaches, called Phrase based Technique (PHT) uses phrases to represent documents, aiming at capturing the main phrases present in the document. A set of phrases is represented as an ATN. One of the main problems in this approach is to construct ATN that can capture all possible patterns. This paper provides a frame work that is essential for capturing the most of the patterns used in English Language and proposes a way to automatically represent documents. Experiments have been performed on small set of documents and shown that phrases are more effective than keywords in terms of content indicators.

In this paper a new converter is proposed for universal line PFC operated in Boundary Conduction Mode. The proposed Modified SEPIC enables the use of lower voltage rated semiconductors compared to other single-switch buck-boost derived topologies with a resulting performance comparable to the boost topology. The operation and the design procedure is described in detail and the proposed converter is experimental verified with a 210V, 100W prototype for the universal line input (90Vac-270Vac).

This paper is devoted to the electromagnetic scattering from an N multilayered cylinder. We consider waveguides in the z direction, that is we look for the solution of Maxwell equations along the z direction. We assume a dielectric core and discuss the problem for the case of general domains. We use an integral equation approach to solve the problem and the Nyström method for the numerical approximation.

This work analyzes the behaviour of wound-cores losses in distribution transformers, as a function of the design parameters of the transformer joint configuration. The configuration used in this paper is called step-lap joint. This analysis is carried out experimentally as well as by using the finite element method. In this research, the effect of the following factors is considered: (a) overlap length and (b) number of laminations per step or group. The design aspects of the wound core are also discussed.
