Artificial Neural Networks (ANNs) have been used in identifying the risk factors for many medical outcomes. In this paper, the risk factors for low Apgar score are introduced. This is the first time, to our knowledge, that the ANNs are used for Apgar score prediction. The medical domain of interest used is the perinatal database provided by the Perinatal Partnership Program of Eastern and Southeastern Ontario (PPPESO). The ability of the feed forward back propagation ANNs to generate strong predictive model with the most influential variables is tested. Finally, minimal sets of variables (risk factors) that are important in predicting Apgar score outcome without degrading the ANN performance are identified

There is now an increasing demand for sharing document images and image data for process integration among enterprises. Web services technology has recently been widely proposed and gradually adopted as a platform for supporting integrations. There are so far no holistic solutions to tackle the various protection issues in this area, especially regarding the security and privacy protection requirements in cross-enterprise progress integration. We propose the exchange of document images through a Document Image Exchange Platform (DIEP), replacing ad-hoc and manual exchange practices. We show how contemporary technologies of Web services and watermarking can help archive images with layered implementation architecture. Through dedicated Web services technologies with watermarking mechanism, not only can the development, deployment, and maintenance of software be streamlined, the privacy protection in document image exchanges as required by disparate processes can also be much facilitated.

The outdoor service robot, which we call OSR-02, is presently under development intended for cleaning up urban areas by means of collecting discarded trash such as plastic bottles, cans, plastic bags and so on. Additionally, we have developed a novel sensor system for the achievement of the task by this robot; it is constructed with LRF (laser rangefinder), two cameras, and three stepping motors. In this paper, we describe the sensor system and its applications

The area equivalent principle is simple to generate sinusoidal pulse width modulation (SPWM) waves. The SPWM waves that are generated by output of pulse width modulation (PWM) in single-chip microcomputer or digital signal processor (DSP) are analyzed harmoniously. In the SPWM waves there are PWM waves of same duty ratio per small equal time. There are different duty ratios in different small equal time. Actual SPWM waves are unfurled by the Discrete Fourier Series (DFS) with a computer. The analytic results of harmonics are more accurate and worth. © 2006 IEEE.

A genetic algorithm for the optimization of cable routing

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.

Background subtraction under varying illumination

Background subtraction is widely used as an effective method for detecting moving objects in a video image. However, background subtraction requires a prerequisite in that image variation cannot be observed, and the range of application is limited. Proposed in this research paper is a method for detecting moving objects by using background subtraction that can be applied to cases in which the image has varied due to varying illumination. This method is based on two object detection methods that are based on different lines of thinking. One method compares the background image and the observed image using invariant features of illumination. The other method estimates the illumination conditions of the observed image and normalizes the brightness before carrying out background subtraction. These two methods are complementary, and highly precise detection results can be obtained by ultimately integrating the detection results of both methods. © 2006 Wiley Periodicals, Inc.

New Fuzzy Color Median Filter

Journal of Intelligent and Robotic systems: Theory and Applications 2005年第4期41卷 315-330页

Median filters are widely used in color image processing. In this paper a new fuzzy median filter is introduced, suitable for the removal of impulse noise in color images. In order to apply a median operator, some kind of ordering of vectors is required. Thus, a vector ordering scheme in the HSV color space using fuzzy if-then rules is described and then the median value operator is defined. The weighted fuzzy median is also studied. This filter performs significantly better in impulse noise removal, compared to other reported median filters. Experimental and comparative results of the application of the proposed filter and other similar reported filters, exhibit the superiority of the proposed method when applied to degraded color images. © 2004, Springer.

Distributed collaboration over the Internet has become increasingly common in recent years, supported by various technologies such as virtual workspace systems. Often such collaboration is ad-hoc, and virtual workspaces are set up anew for each new instance of collaboration. We propose that much of the ad-hoc collaboration can be captured and transformed into patterns for reuse in future collaboration. This paper presents the results of the past five years of our work in this area. We introduce the notion of patterns of virtual collaboration;present a framework for extracting patterns of work in virtual workspace systems;and introduce an information model of virtual collaboration. We then present an overview of our data and process mining methods and reverse engineering techniques for discerning work processes carried out through virtual workspace systems. Finally we present our visual mining techniques that we use to discern aspects of work processes in virtual workspaces.
