Finger Pose Estimation Based on Anatomical Motion Constraints

SICE Journal of Control, Measurement, and System Integration 2009年第6期2卷 357-364页

作者： Akinori Sasaki Hiroshi Hashimoto Sho Yokota Yasuhiro Ohyama School of Computer Science Tokyo University of Technology Master Program of Innovation for Design and Engineering Advanced Institute of Industrial Technology Department of Mechanical Engineering Setsunan University

In this paper, a finger pose estimation method is presented. A direct use of fingers is useful in some applications which require handling of 3D position information. Our finger pose estimation method exploits anatomical constraints on finger motion and ring-shaped markers to achieve simple and practical measurements applicable to daily life situations. The use of anatomical constraints ensures that no exact placement of the markers is required.

As we are moving along with emerging technologies the storage of data will no longer be in our conventional single dimensional raw data. The relational data can be further identified with spatial and non-spatial relationship. This is to examine whether clustering approach has any role to play in spatial data mining. This paper explains spatial clustering under statistical method of analysis for discovering the knowledge which is encapsulated in the spatial database. This study emphasis the spatial clustering approach accomplished through algorithms such as PAM and CLARA and let us to come across the limitations of PAM method. To the end, This work ushers that spatial data mining is a promising field, with fruitful research results and carries many challenging issues.

This paper presents an incremental method to 3D transformation by VQS structures. For interpolated scaling, rotation and translation between two animation key frames, with constant intervals in size, angle and distance, the proposed approach reduces the VQS transformation cost by more than an half. Moreover, all interpolations for VQS key frames are performed implicitly at no cost. In other words, the expensive trigonometric functions in quaternion Slerp and exponential functions in scalar interpolation are completely eliminated from the process. The method is fast, accurate, numerically stable and also preserves all geometric characteristics of the original transformation and interpolation algorithms.

There has been a growing interest among the researchers in the area of soft computing assisted material modeling in general and modeling of concrete in particular. Their results look very promising. Concrete is a heterogeneous material with complex behavior and is not amenable for crisp mathematical predications. Most of the inferences regarding the material behavior are formulized after going through experimental results that consists of equipment imprecision, tolerances and human factor. The analytical modeling of concrete using traditional methods is arduous and not robust. Further, the mathematical models developed using traditional statistical methods are generally based on assumed relationships and do not have the true predicting capability outside the experimental domain used for their development. Unlike traditional parametric methods, the soft computing methods do not assume a relationship between various parameters and concrete performance. The relationship is rather generated from the experimental data provided to build and train the model. This paper makes a modest attempt to present an elaborative discussion on the applications of soft computing techniques in concrete technology and their advantages. The published research work pertaining to applications of constituents of soft computing in general and hybrid systems in particular are discussed. The paper concludes with a briefing on the contribution of authors in this area. Copyright © 2007 IICAI.

This paper studies the stability robustness of a multirate system where sensing data are obtained n (n > 1 is an integer) times slower than the control variables are updated. The robust controller is designed for such systems by using the H infin technique. The procedure to check the robust stability of the controlled system is presented; and an illustrative example is given to show the effects of the value n on the robust stability of the system with the designed H infin controller.

作者： M. Feemster D.M. Dawson A. Behal W. Dixon Matthew Feemster received the B.S degree in Electrical Engineering from Clemson University Clemson South Carolina in December 1994. Upon graduation he remained at Clemson University and received the M.S. degree in Electrical Engineering in 1997. During this time he also served as a research/teaching assistant. His research work focused on the design and implementation of various nonlinear control algorithms with emphasis on the induction motor and mechanical systems with friction present. He is currently working toward his Ph.D. degree in Electrical Engineering at Clemson University. Darren M. Dawson was born in 1962 in Macon Georgia. He received an Associate Degree in Mathematics from Macon Junior College in 1982 and a B.S. Degree in Electrical Engineering from the Georgia Institute of Technology in 1984. He then worked for Westinghouse as a control engineer from 1985 to 1987. In 1987 he returned to the Georgia Institute of Technology where he received the Ph.D. Degree in Electrical Engineering in March 1990. During this time he also served as a research/teaching assistant. In July 1990 he joined the Electrical and Computer Engineering Department and the Center for Advanced Manufacturing (CAM) at Clemson University where he currently holds the position of Professor. Under the CAM director's supervision he currently leads the Robotics and Manufacturing Automation Laboratory which is jointly operated by the Electrical and Mechanical Engineering departments. His main research interests are in the fields of nonlinear based robust adaptive and learning control with application to electro-mechanical systems including robot manipulators motor drives magnetic bearings flexible cables flexible beams and high-speed transport systems.

In this paper, we extend the observer/control strategies previously published in [25] to an n -link, serially connected, direct drive, rigid link, revolute robot operating in the presence of nonlinear friction effects modeled by the Lu-Gre model. In addition, we also present a new adaptive control technique for compensating for the nonlinear parameterizable Stribeck effects. Specifically, an adaptive observer/controller scheme is developed which contains a feedforward approximation of the Stribeck effects. This feedforward approximation is used in a composite controller/observer strategy which forces the average square integral of the position tracking error to an arbitrarily small value. Experimental results are included to illustrate the performance of the proposed controllers.

During the past few years, the New Jersey institute of technology (NJIT) has initiated several projects to determine best practices in distance learning education and to apply them to courses in the Newark College of Engineering. The engineering college has lagged behind other colleges within the university in developing and implementing distance learning courses, and concerns about the quality of distance learning courses are one of the main reasons for this. The Office of Institutional Research and Planning at NJIT has undertaken a study of distance learning courses offered during the 2003-2004 academic year. The study examines a total of 150 courses, 3, 491 students and 7,701 course enrollments;approximately 1/5 of the enrollments are in distance learning courses and the remaining students enrolled in traditional face-to-face courses and served as a control group. The study examines a wide variety of parameters, including overall course performance, student satisfaction with the course and the instructor, delivery format for distance learning courses (multimedia, text, multimedia + text), instructor rank, instructor training for distance learning instruction, distance learning platform (WebCT® and WebBoard®), and ease of use of technology. This paper presents the results of this study and how they can be applied to produce improved distance learning courses in the engineering college, in all colleges within NJIT, and at other universities. Among its most significant results, the study highlights the need for instructors to receive training in teaching, learning, and technology;the preference of students for courses that use multiple delivery formats;and the greater student satisfaction at NJIT for courses that use WebCT as their asynchronous learning network platform. © American Society for Engineering Education, 2006.
