The advancement of traffic makes world more and more internationalized and increases frequency of communication between people who come from different cultures. Differences in their conversation go beyond the languages they speak to the non-verbal behaviors they express while talking. To improve the abilities of the embodied conversational agents (ECAs) while interacting with human users we are working on the ECA based application, a tour guide of city Dubrovnik that servers visitors in Japanese, Croatian and general western cultures speaking in English. This paper presents the overall architecture and explains possible extension with another culture. It describes issues we met while making agent talk in Croatian and proposed solutions.

In this paper we introduce a new approach to train neurofuzzy networks using the participatory learning concept. The participatory learning paradigm tends to emulate the human learning mechanism where an acceptance mechanism determines which observation is used for learning based upon their compatibility with the current beliefs. The performance of the proposed learning scheme is illustrated by an example involving a nonlinear system modeling problem: the thermal modeling of power transformers. Comparisons with other methods reported in the literature and between two dual network structures are also included. The experimental results show the effectiveness of participatory learning in neurofuzzy networks training.

The Generation Challenge programme (GCP) is a global crop research consortium directed toward crop improvement through the application of comparative biology and genetic resources characterization to plant breeding. A key consortium research activity is the development of a GCP crop bioinformatics platform to support GCP research. This platform includes the following: (i) shared, public platform-independent domain models, ontology, and data formats to enable interoperability of data and analysis flows within the platform;(ii) web service and registry technologies to identify, share, and integrate information across diverse, globally dispersed data sources, as well as to access high-performance computational (HPC) facilities for computationally intensive, high-throughput analyses of project data;(iii) platform-specific middleware reference implementations of the domain model integrating a suite of public (largely open-access/-source) databases and software tools into a workbench to facilitate biodiversity analysis, comparative analysis of crop genomic data, and plant breeding decision making.

In reconfigurable systems, reconfiguration latency is a very important factor impact the system performance. In this paper, a framework is proposed that integrates the temporal partitioning and physical design phases to perform a static compilation process for reconfigurable computing systems. A temporal partitioning algorithm is proposed which attempts to decrease the time of reconfiguration on a partially reconfigurable hardware, This algorithm attempts to find similar single or pair of operations between subsequent partitions. Considering similar pairs instead of single nodes brings about less complexity for routing process. By using this technique, smaller reconfiguration bit-stream is obtained, which directly decreases the reconfiguration overhead time at the run-time. A complementary algorithm attempts to increase the similarity of subsequent partitions by searching for similar pairs and using a technique called dummy node insertion, An incremental physical design process based on similar configurations produced in the partitioning stage improves the metrics over iterations. © 2006 IEEE.

An integrated temporal partitioning and physical design framework for real-time reconfigurable systems

WSEAS Transactions on Circuits and Systems 2006年第2期5卷 248-255页

作者： Mehdipour, Farhad Zamani, Morteza Saheb Ahmadifar, Hamid. R. Sedighi, Mehdi Murakami, Kazuaki Computer and IT Engineering Department Amirkabir University of Technology # 424 Hafez Ave Tehran Iran Engineering Faculty Guilan University Engineerinf Faculty Rasht Iran Department of Informatics Graduate School of Information Science and Electrical Engineering Kyushu University 6-1 Kasuga-Koen Kasuga Fukuoka 816-8580 Japan

In a reconfigurable system, configurations are swapped in/out at run-time duration. The number of reconfigurations is an important factor to determine the overall run-time and reconfiguration overhead time is usually the dominant time factor. We have generated a framework for temporal partitioning and physical design of data flow graphs for a real-time environment. In this work, a temporal partitioning algorithm is presented which partitions data flow graphs in a real-time domain. Timing constraint is a critical factor in temporal partitioning of real-time reconfigurable design. We propose an incremental temporal partitioning algorithm for real-time reconfigurable applications. In this algorithm, the maximum number of partitions which is appropriate for running input data flow graph at the specified time is determined. Also, appropriate device size is determined with respect to the number of partitions. An iterative partitioning process tries to perform the partitioning to obtain desired the number of partitions after an initial partitioning. Also, a post processing algorithm attempts to minimize the required device size. In this algorithm, selecting the appropriate nodes and moving them between subsequent partitions results in more area balanced partitions and less number of partitions.

In this paper the authors propose a structural method for a genetic algorithm (GA) for the optimization problem of cable routing in which cables have to be laid optimally. When there are no limits on the layout routes, the optimal routes for the individual cables can be found using the Dijkstra method in a finite discrete graph. However, when there are limits on the capacity in the layout routes, optimization cannot be performed using the Dijkstra method. The proposed GA is a two-level hierarchical GA that uses chromosome coding involving two levels. The routes for each cable and the combinations of cable routes are defined respectively, and layout route selection is optimized overall through genetic operations involving these levels. Block crossover and block mutation are used as genetic operations in the first level. In addition, a method to take advantage of lethal genes, which do not satisfy the constraints and are generated in the second level is used. computer simulations confirm that the two-level hierarchical GA with these genetic operations functions effectively for the optimization problem of cable routing. © 2006 Wiley Periodicals, Inc.

Edge detection using clustering algorithms

Edge detection is an important topic in image processing and a main tool in pattern recognition and image segmentation. Many edge detection techniques are available in the literature. 'A number of recent edge detectors are multiscale and include three main processing steps: smoothing, differentiation and labeling' (Ziau and Tabbone, 1997). This paper, presents a proposed method which is suitable for edge detection in images. This method is based on the use of the clustering algorithms (Self-Organizing Map (SOM), K-Means) and a gray scale edge detector (Canny, Generalized Edge Detector (GED)). It is shown that using the grayscale edge detectors may miss some parts of the edges which can be found using the proposed method.

Most edge detection algorithms include three main stages: smoothing, differentiation, and labeling. In this paper, we evaluate the performance of algorithms in which competitive learning is applied first to enhance edges, followed by an edge detector to locate the edges. In this way, more detailed and relatively more unbroken edges can be found as compared to the results when an edge detector is applied alone. The algorithms compared are K-Means, SOM and SOGR for clustering, and Canny and GED for edge detection. Perceptionally, best results were obtained with the GED-SOGR algorithm. The SOGR is also considerably simpler and faster than the SOM algorithm.

In this paper, we discuss edge detection by first using a clustering algorithm followed by a known edge detection filter such as Canny or Generalized Edge Detector (GED). We developed a new clustering method called Self-Organizing Global Ranking (SOGR). Comparative results with multispectral satellite images including SOGR, SOM and K-Means clustering methods are discussed. The results show that the two-stage algorithms are better than single stage edge detector algorithms. © 2005 IEEE.
