A series of experiments aimed to generate and learn fuzzy models for the valuation of residential premises was conducted using the KEEL tool (knowledge extraction based on evolutionary learning). Four regression and four post-processing algorithms were applied to several data sets. They referred to sales/purchase transactions of residential premises, which were derived from the cadastral system and the registry of real estate transactions. The results proved the usefulness of the tool to carry out laborious and tedious investigation in a relatively short time. Further research is needed to determine to what extent data coming from such sources allow to build the real estate valuation models.

By using the ATLAS detector, observations have been made of a centrality-dependent dijet asymmetry in the collisions of lead ions at the Large Hadron Collider. In a sample of lead-lead events with a per-nucleon center of mass energy of 2.76 TeV, selected with a minimum bias trigger, jets are reconstructed in fine-grained, longitudinally segmented electromagnetic and hadronic calorimeters. The transverse energies of dijets in opposite hemispheres are observed to become systematically more unbalanced with increasing event centrality leading to a large number of events which contain highly asymmetric dijets. This is the first observation of an enhancement of events with such large dijet asymmetries, not observed in proton-proton collisions, which may point to an interpretation in terms of strong jet energy loss in a hot, dense medium.

This paper proposes a generic design for 3D model retrieval. It has been developed in cooperation with EADS, which deals with computer Aided Design / computer Aided engineering (below CAD/CAE) data through the product life cycle. Sharing these models with users across the enterprise is a challenging task. CAD/CAE models may be hundreds of megabytes large and stored in proprietary formats. Browsing and previewing this data efficiently requires new tools. One way to leverage the collaboration in and outside of CAD domains is to offer through a repository an access to a neutral 3D data format. Also functionalities for semantic enrichment of 3D models, for the retrieval of context sensitive information and for 3D model retrieval based on 3D similarity search and CBIR techniques should be provided.

Based on the ZeroX algorithm, we proposed a fast and efficient crosstalk-free algorithm called the Fast ZeroX algorithm for solving optical crosstalk problem in omega networks. In our approach, we introduced the concept of inverse conflict matrix (iCM), another representation of a conflict matrix in which it summarizes all possible conflicts between each node in the network. Using iCM, the ZeroX algorithm is simplified, thus improved by reducing the time needed for routing process. From our simulation results, it is shown that our approach yields better performance in terms of minimal routing time in comparison to the original ZeroX algorithm.

The aim of this paper is to present a new design for a controller unit using base 3, which will be named ternary controller unit. The ternary controller unit is planned to be the future brain of the ternary central processing unit. The ternary controller unit controls the fetch and execution cycles of instructions. To achieve this task, the ternary controller unit receives instructions from the instruction register that is ternary, then a ternary decoder decodes those instructions. Finally the ternary controller unit sends the resulting control word (control signals) to other registers and logic circuits of the ternary central processing unit to determines their function at each phase of the fetch-execute cycle.

Quantum computing algorithms are considered for several problems in graph theory. Classical algorithms involve searching over some space for finding the minimal spanning tree problem in a graph. We modify classical Primpsilas algorithm and replace quantum search instead of classical search, of which it will lead to more efficient algorithm. Also we proposed the structure for non-classical algorithms and design the various phases of the probabilistic quantum-classical algorithm for classical and quantum parts. Finally, we represent the result of implementing and simulating Primpsilas algorithm in the probabilistic quantum-classical algorithm.

Current Mode Converter for Dielectric Barrier Discharge Lamp

Current Mode Converter for Dielectric Barrier Discharge Lamp

39th IEEE Power Electronics Specialists Conference (PESC 2008), vol.6

作者： Rafael Diez Hubert Piquet Sounil Bhosle Jean-Marc Blaquiere Languages Informatics Systems and Software Engineering Department Faculty of Computer Science Université de Toulouse Toulouse France

This paper presents a novel concept of supplying a dielectric barrier discharge (DBD) lamp. An electrical model of the lamp is used in a circuit simulator to study the interactions between the converter and the load, which presents a capacitive nature. The current mode supply is chosen instead of the classical voltage mode, in order to respect the causality considerations concerning these interactions. The converter is designed as a unidirectional current source in series with an H-bridge that inverts the current direction in the lamp each half cycle. Two different structures are presented to compose the unidirectional current source: a Boost based converter and a Buck-Boost based converter. Both converters are analyzed using the state plane and implemented, obtaining measurements that comply with the current mode concept. The presented structures allow the control of the current duration and amplitude, thus, the operating point in the discharge. This concept is the basis for the studies of correlation between the gas current and the UV emission.

This paper is concerned with prototype development and motion control of a dolphin-like underwater robot. The propulsion and maneuvering of the robotic dolphin are realized with the flapping motion of the mechanical flippers and the combined heaving and pitching motions of the fluke. Mechanical design and control of the flipper apparatus and the flexible tail mechanism are presented. Through coordinated control of the propulsors, several swimming movements are designed. Preliminary experimental results verify the effectiveness of the proposed design scheme.
