This paper presents recently introduced learning algorithm called extreme learning machine (ELM) for single-hidden layer feed-forward neural-networks (SLFNs) which randomly chooses hidden nodes and analytically determines the output weights of SLFNs. The ELM avoids problems like local minima, improper learning rate and over fitting commonly faced by iterative learning methods and completes the training very fast. We have evaluated the multicategory classification performance of ELM on five different data sets related to bioinformatics namely, the Breast Cancer Wisconsin data set, the Pima Diabetes data set, the Heart-Statlog data set, the Hepatitis data set and the Hypothyroid data set. A detailed analysis of different activation functions with varying number of neurons is also carried out which concludes that Algebraic Sigmoid function outperforms all other activation functions on these data sets. The evaluation results indicate that ELM produces better classification accuracy with reduced training time and implementation complexity compared to earlier implemented models.

Paper shows direct connection and implementation way of designed control schemas of prepared applications to an industrial WinPLC. Paper deals with industrial realization of feedback control of demanding applications on their control, control algorithms and visualization together with design, implementation and real time control from MATLAB/Simulink Environment. Described is a way to produce a permanent solution in control applications that are fully prepared, designed and implemented directly from MATLAB/Simulink to the target control platform. As a part, the mentioned solution is using a multiplatform control system REX as a bridge between MATLAB and target platforms. These methods allow minimizing costs of development of control of applications, because it produces target permanent realizations in comparison to classical development methods that usually need expensive real time measurement cards and produce only one purpose development solution. As next benefit the application is created for visualization the data from RT database during the measurement and control process. This last benefit produce an interesting data from real control process to give a next reason to use of WinCon solution.

We present a dynamic partitioning strategy that selects test cases using online feedback information. The presented strategy differs from conventional approaches. Firstly, the partitioning is carried out online rather than off-line. Secondly, the partitioning is not based on program code or specifications; instead, it is simply based on the fail or pass information of previously executed test cases and, hence, can be implemented in the absence of the source code or specification of the program under test. The cost-effectiveness of the proposed strategy has been empirically investigated with three programs, namely SPACE, SED, and GREP. The results show that the proposed strategy achieves a significant saving in terms of total number of test cases executed to detect all faults.

Less degree-of-freedom robots are useful for special applications. Specifically, practical application of 4-DOF parallel mechanism has been rare, though synthesis on this type has been conducted quite a few. Recently, we proposed a revolute joint-based 3T1R 4-DOF parallel mechanism having Schonflies motions whose output rotational motion is a roll motion. This work proposes another type of a new 3T1R 4-DOF parallel mechanism having Schonflies motions whose rotational motion is a pitch motion. The position analysis and kinematic modeling for the mechanism are performed, and its workspace size and kinematic characteristic with respect to the kinematic isotropic characteristic are examined. To support high potential of the mechanism for real applications, three different versions are suggested and each motion capability is verified through its simulator. Finally, a prototype is developed to verity its actual motion capability.

The paper describes methods of comparing calculated ECG signal with real signal. Five examination methods of ECG-signal reconstruction from reduced system were proposed in this description. These methods prove reconstruction and evaluate results. They are based on statistic methods, nonparametric approaches and autoregressive models.

This paper is concerned with understanding the connection between the existing Internet congestion control algorithms and the optimal control theory. The available resource allocation controllers are mainly devised to derive the state of the system to a desired equilibrium point and, therefore,they are oblivious to the transient behavior of the closed-loop system. This work aims to investigate what dynamical functions the existing algorithms maximize(minimize). In particular, it is shown that there exist meaningful cost functionals whose minimization leads to the celebrated primal and dual congestion algorithms. An implication of this result is that a real network problem may be solved by regarding it as an optimal control problem on which some practical constraints, such as a realtime link capacity constraint, are imposed.

This paper describes an interactive tool focused on teaching and learning basic concepts on multivariable control systems. Most industrial processes are represented by multivariable systems and thus the teaching and learning of basic concepts on multivariable control is a key factor in control engineering education. In this sense, the interactive tool presented in this paper is aimed to introduce basic ideas on multivariable control systems mainly focused on interaction and pairing concepts. © 2009 EUCA.

Image password lock system by tracing position information of the pupil

引用

Optica Applicata 2009年第1期39卷 149-160页

作者： Lin, Chern-Sheng Lay, Yun-Long Lin, Chi-Chin Chiu, Chuang-Chien Yeh, Mau-Shiun Department of Automatic Control Engineering Feng Chia University Taichung Taiwan Department of Electronic Engineering National Chinyi University of Technology Taiwan Department of Computer Science and Information Engineering National Taiwan University Taiwan Chung-Shan Institute of Science and Technology Lung-Tan Tao-Yuan Taiwan

In this paper, a new method for an improved image password lock system by tracing position information of the pupil is described. The present technology relates to an efficient auto-detecting function, and in particular, to an image password lock system, which can provide the benefits of a novel password input mode without any contact. In this system, a PC camera device detects a movable target object to read a dynamic eye image data. Moreover, the dynamic eye image data has a predetermined shooting range set to be a whole-region image, and the whole-region image has a central region and a plurality of specific password regions. A target eye image is displayed by a display device, and then processed by an image processing device, thereby calculating a center coordinate point of the target eye image in the dynamic image data, compiling a password constituted by a movement position of the target object image, displaying the password, and validating the password. Therefore, the benefits of a novel password input mode without any contact, an efficient anti-theft function, are provided.
