In this paper, a method for hand posture recognition, which is robust for hand posture changing in an actual environment, is proposed. Conventionally, a data glove device and a 3D scanner have been used for the feature extraction of hand shape. However, the performance of each approach is affeected by hand posture changing. Therefore, this paper proposes the posture fluctuation model for efficient hand posture recognition, based on 3D hand shape and color feature obtained from a stereo camera. A large set of dictionary for posture recognition is built by various leaned hand images which were auto-created from one scanned hand image, based on plural proposed models. In order to show the effectiveness of proposed method, performance and processing times for posture recognition are compared to conventional method. In addition, we perform the evaluation experiment by using the Japanese sign language. © 2010 IEEE.

Middleware facilitates the development of distributed systems by accommodating heterogeneity, hiding distribution details and providing a set of common and domain specific services. It plays a central and essential role for developing distributed systems. However, middleware is considered a mean rather than core elements of development process in the existing distributed systems software process. This paper explains the concept of middleware by categorizes middleware and analysis the problems of current middleware architectures. It also extracts three essential non-functional requirements of middleware and proposes a middleware-based distributed systems software process. The proposed software process consists in five phases: requirements analysis, design, validation, development and testing. The characteristics of middleware are considered in the entire software process. © 2009 ACM.

Aspect-oriented programming (AOP) and model-driven architecture (MDA) are very important as technologies to resolving lifecycle challenges of DRE systems, including requirements analysis, design, validation, development and testing. This paper provides two contributions to the study of DRE systems development. First, analyzes non-functional requirements of DRE systems. Second, proposes a new aspect-oriented middleware based DRE systems software process, and applies AOP and MDA technologies to the process. The characteristics of middleware are considered in the entire DRE systems software process from requirements analyze phase to testing phase.

Web service technologies are becoming increasingly important for integrating service-oriented applications. The Web services reverse engineering process becomes necessary in order to facilitate the reuse and composition of Web services. This paper describes a model driven Web service reverse engineering process, where Web service descriptions (WSDL) are transformed to UML models, then the generated UML models are integrated into composite Web services, finally the new Web service descriptions (OWL) are generated.

IEEE Conference on Control technology and applications (CCTA)

作者： Alan Mutka Ivica Draganjac Zdenko Kovacic Zeljko Postruzin Ranko Munk Faculty of EE&C Department of Control and Computer Engineering LARICS-Laboratory of Robotics and Intelligent Control Systems University of Zagreb Zagreb Croatia Organization of Technology Development and Application HRID Limited Zagreb Croatia

In this paper a system for control and 3D visualization of a manipulator for weld inspection of nuclear reactor vessels is described. Based on client-server TCP/IP software architecture, the presented control system enables an operator to perform the entire inspection procedure remotely over a network, avoiding exposure to dangerous radiation which is commonly present in nuclear reactor environments. The developed graphical user interface provides all necessary tools needed for planning robot scan trajectories, their verification on a virtual 3D model and execution on a remote robot. In addition, the weld inspection process can be observed in parallel on a virtual robot and reactor vessel model and on live video streams captured by two special cameras mounted on the robot.

E-Learning is increasingly being integrated into universities as a new means of learning and teaching. The web-based learning system can increase the learning efficiency. This paper presents the design and implementation of a web-based learning system of operating system course. The proposed web-based learning system has four subsystems: learning and teaching subsystem, student subsystem, teacher subsystem and administrator subsystem. Development tools, system architecture and MDA are also described. © 2008 IET.

Effects of average luminance level of displayed images, viewers age, and screen illuminance on preferred luminance of LCDs

作者： Kubota, Satoru Hanehara, Ryo Nakamura, Yoshitomo Nomoto, Kohei Yamakawa, Masaki Faculty of Science and Technology Seikei University 3-3-1 Kichijoji-kitamachi Musashino-shi Tokyo 180-8633 Japan Advanced Technology R and D Center Mitsubishi Electric Corporation 1 Zusho Baba Nagaokakyo-shi Kyoto 617-8550 Japan Industrial Design Center Mitsubishi Electric Corporation 5-1-1 Ofuna Kamakura-shi Kanagawa 247-8501 Japan Computer and Consumer Application Engineering Dept.

We investigated what influences the average luminance level (ALL) of displayed images, screen illuminance, and viewers ages had on the preferred luminance of LCDs. Twenty young subjects (mean age: 21.8) and 24 seniors (mean age: 68.9) adjusted the luminance of a 17-inch 1000: 1 LCD monitor to their preferred levels under different experimental conditions. The results indicate that the preferred luminance of LCDs corresponded to the following formula: Lp=k x ALLα. This is where Lp is the peak white luminance of the LCDs, k is a constant, and ALL is the average luminance level of the displayed images. Here, α is a constant from -0.19 to -0.20 for the seniors and from -0.14 to -0.17 for the young subjects. The influences of age-related changes in vision and ambient lighting on the luminance requirements for LCDs are also discussed. These results can be applied to the design of luminance-control systems for LCDs.

This paper proposes a new concept of the genetic robot which has its own robot genome, in which each chromosome consists of many genes that contribute to defining the robotpsilas personality. The large number of genes also allows for a highly complex system, however it becomes increasingly difficult and time-consuming to ensure reliability, variability and consistency for the robotpsilas personality while manually initializing values for the individual genes. To overcome this difficulty, this paper proposes an evolutionary algorithm for a genetic robotpsilas personality (EAGRP). EAGRP evolves a gene pool that customizes the robotpsilas genome so that it closely matches a simplified set of features desired by the user. It does this using several new techniques. It acts on a 2 dimensional individual upon which a new masking method, the Eliza-Meme scheme, is used to derive a plausible individual given the restricted preference settings desired by the user. The proposed crossover method allows reproduction for the 2-dimensional genome. Finally, the evaluation procedure for individuals is carried out in a virtual environment using tailored perception scenarios.

The paper presents the theoretical background and realization of a KM system for the technically advanced customer and product support in the Ambient Intelligence (AmI) domain. Current products include more and more elements of AmI. AmI area is still not state-of-the art in market available products, but there is a clear trend towards products which will be fully based or include different forms of AmI. The paper presents a new KM system using CBR to support so-called AmI product extension. The product extension includes customer support in solving different problems related to the AmI products utilisation. The paper specifically explores the challenges due to increased/more complex interaction between the customers and AmI products. The approach for definition of appropriate set of attributes in CBR system to describe different cases and problems with AmI products is elaborated. The objective is to define a system suitable for AmI products provided by SMEs but capable to cope with the complexity imposed by AmI aspects. The KM system developed and the results of initial testing in industrial environment of SMEs are presented.

In this paper, a new texture feature set based on M-band wavelet analysis is proposed for online Palmprint identification. First, the central part of a palm was decomposed by M-band wavelets transformation, then, 1-norm energy was extracted out as our features, at last, the candidate was found by matching process. The presented experimental results demonstrate the validity of our approach. © 2004 IEEE.
