20.2: Enlarged Viewing Angle of Integral Imaging System by Liquid Crystal Prism

SID Symposium Digest of Technical Papers 2013年第1期44卷

作者： Chih-Wei Chen Yi-Pai Huang Po-Yuan Hsieh Ta-Hsiang Jen Yu-Cheng Chang Yong-Ren Su Myungjin Cho Xiao Xiao Bahram Javidi Department of Photonics & Institute of Electro-Optical Engineering Display Institute National Chiao Tung University Hsinchu Taiwan 30010 Electrical Electronic and Control Engineering Hankyong National University Ansung Korea 456–749 Electrical and Computing Engineering Department University of Connecticut Storrs CT USA 06269

In this paper, we proposed an integral imaging (II) system with a Liquid Crystal (LC) prism array to extend the horizontal viewing angles. The experimental results indicated that the viewing angle is successfully extended by two times without any mechanical movement. We believe that the proposed system is promising for future wide viewing integral imaging systems.

In this paper, a neural network PCA method that integrates neural networks (NN) and principal component analysis (PCA) is used to detect faults in a wastewater treatment plant. The neural networks are used to calculate a non-linear and dynamic model of the process in normal operating conditions. PCA is used to generate monitoring charts based on the residuals calculated as the difference between the process measurements and the output of the networks. It can evaluate the current performance of the process and detects the faults. This technique has been applied to the simulation of a benchmark of a biological wastewater treatment process, a highly non-linear process. The simulation results clearly show the advantages of using this NNPCA monitoring in comparison with classical PCA monitoring. © 2012 IEEE.

This paper is concerned with analyzing a novel model transformation of discrete-time Takagi-Sugeno (T-S) fuzzy systems with time-varying delays and applying it to dynamic output feedback (DOF) controller design. A new auxiliary model is proposed by employing a new approximation for time-varying delay state, and then delay partitioning method is used to analyze the scaled small gain of this auxiliary model. A sufficient condition on discrete-time T-S fuzzy systems with time-varying delays, which guarantees the corresponding closed-loop system to be asymptotically stable and has an induced 2 disturbance attenuation performance, is derived by employing the scaled small gain theorem. Then the solvability condition for the induced 2 DOF control is also established, by which the DOF controller can be found by solving a set of linear matrix inequalities (LMIs). © 2012 IEEE.

Implementation, usage, and maintenance of complex dynamic web forms can be very time consuming, especially when they have a large number of fields which change very often. In combination with fields that require programming for implementation, the complexity further increases. In this article we describe the problem and suggest the framework for easier implementation of such forms. Later, we describe current implementation, its benefits, and propose future work on this subject.

The paper provides the solution of the campion for CDMC2011, a data mining contest. The task for the data mining contest organized in conjunction with the ICONIP20II conference was to learn three predictive models (i.e. a classifier) capable of distinguishing between different classes for three separate tasks. Different combinations of data preprocess, feature selection and classifier learning methods were tried to obtain the best results. The performance of classifiers are improved by ensemble learning method. The final accuracy on test dataset shows our methods outperformed others. Copyright © 2012 Binary Information Press.

Derivation of the mathematical model for a robot fish considering forward motion and yaw angle kinematics is presented. This model also includes details of the hydrodynamic force by considering the condition of fish swimming underwater. The nonlinear dynamical model in Carangi form locomotion type is derived by use of Lagrange's equation, which concerning about 4 links of fish robot equivalent model similar to the 4-link planar robot manipulator. Computer simulations conduct both in terms of open-loop response and animation motion of the fish robot swimming. These results indicate feasibility of the model for the robot with swimming speed 0.48 m/s and yaw swing angle ±12 degree. The model derived will be served as a basis for further investigation of control design for the complicated object.

This study aimed to test a protocol of measurements based on Biophotogrammetry to Analysis of Respiratory Mechanics (BARM) in healthy children. Seventeen normal spirometric children (six male and 11 female) were tested. Their performed maneuvers of forced inspiratory vital capacity were recorded in the supine position. The images were acquired by a digital camera, laterally placed to the trunk. Surface markers allowed that the files, exported to CorelDraw (R) software, were processed by irregular trapezoids paths. Compartments were defined in the thoracic (TX), abdominal (AB) and the chest wall (CW). They were defined at the end of an inspiration and expiration, both maximum, controlled by a digital spirometer. The result showed that the measured areas at the inspiratory and expiratory periods were statistically different (p<0.05). It reflects the mobility of CW and compartments. In conclusion, the proposed method can identify the breathing pattern of the measured subject using images in two dimensions (2D).

International Conference on Manipulation, Manufacturing and Measurement on the Nanoscale (3M-NANO)

作者： Ming-Dao Wu Cheng-Chun Huang Wen-Pin Shih Sergej Fatikow Department of Mechanical Engineering National Taiwan University Taipei Taiwan Division of Microrobotics and Control Engineering Department of Computing Science University of Oldenburg Oldenburg Germany

We electrothermally determined the internal electrical resistivity of a single carbon nanocoil (CNC) which was assembled on the AFM tip. A heat-transfer modeling which considered the Joule's heat was employed to extract the electrical resistivity. The current and resistance of the loop circuits were applied in the calculation in which the thermal measurement was not required. During the electrical measurement, the overall resistance of the heating loop depended on the current variation and decreased abruptly at the beginning of the measurement. It was suggested that the contact resistances between the CNC and metal electrodes were eliminated due to the shortened difference of the work functions between the two materials. The developed electrothermal model agreed well with the experiment at steady state and gave the CNC resistivity of 1.64*10 -4 ~8.81*10 -4 Ω-m. This result confirmed the amorphous phase of the synthesized CNC.

Derivation of the mathematical model for a robot fish considering forward motion and yaw angle kinematics is presented. This model has included details of the hydrodynamic force by considering the condition of fish swimming underwater which wasn't revealed in the previous literature. The nonlinear dynamical model in Carangiform locomotion type is derived by use of Lagrange's equation, which concerning about 4 links of fish robot equivalent model similar to the 4-link planar robot manipulator. Computer simulations have conducted both in terms of dynamic response and animation motion of the fish robot swimming. These results indicate feasibility of the model for the designed robot. The tracking simulation by means of simplify proportional controller reveals the feasibility of path-tracking control for the fish robot while swimming. The model derived can be served as a basis for further investigation of compatible control design for sophisticated objectives.

This paper is focused on the problem of H_∞ filtering for a class of discrete-time T-S fuzzy time-varying delay systems. Our interest is how to design full- and reduced-order filters that guarantee the filtering error system to be asymptotically stable with a prescribed H_∞ performance. Sufficient conditions for the obtained filtering error system are proposed by applying an input-output approach and a two-term approximation method, which is employed to approximate the time-varying delay. The corresponding full and reduced-order filter design is cast into a convex optimization problem, which can be efficiently solved by standard numerical algorithms.
