1. Undershoot Reduction in Discrete-Time ADRC of NMP Plant by Parameters Optimization

Tong Wu, Weicun Zhang
Pages: 1 - 4
Undershoot phenomena caused by unstable zeros of non-minimum-phase (NMP) plant is difficult to deal with in active disturbance rejection control (ADRC). This paper proposes a new method to reduce undershoot by optimizing the controller parameters of discrete-time ADRC system. Simulation results are given...

6. Estimating Age on Twitter Using Self-Training Semi-Supervised SVM

Tatsuyuki Iju, Satoshi Endo, Koji Yamada, Naruaki Toma, Yuhei Akamine
Pages: 24 - 27
The estimation methods for Twitter user’s attributes typically require a vast amount of labeled data. Therefore, an efficient way is to tag the unlabeled data and add it to the set. We applied the self-training SVM as a semi-supervised method for age estimation and introduced Plat scaling as the unlabeled...

8. Clinical Evaluation of UR-System 2 for Recovery of Motor Function of Plegic Upper Limb after Stroke

Hirofumi Tanabe, Masahiro Mitsukane, Norihiro Toya, Ryosuke Takeichi, Hitomi Hattori, Yoshifumi Morita, Yoshiaki Takagi, Norio Hasegawa
Pages: 33 - 36
We developed a new training system UR-System 2 for restoring motor function of the upper limb after stroke in patients with hemiplegia. And then, we conducted clinical evaluation of the therapeutic effect of training with the UR-System 2 in six patients. The UR-System uses Proprioceptive Neuromuscular...

12. Self-identification of Mental State and Self-control through Indirect Biofeedback – Indirect Representation and Placebo Effect

Madoka Takahara, Jilin Huang, Ivan Tanev, Katsunori Shimohara
Pages: 50 - 54
This paper describes a possible new scheme for a user with mental health problems to identify his/her own mental state and control it. For that purpose, we propose an indirect biofeedback system which represents physiological information with color and shape, and enables the user to grasp his/her inner...

13. Automated Processing of Multiple-Brightness Peak Histogram Image Using Curvature and Variance Estimation

Yusuke Kawakami, Tetsuo Hattori, Yoshiro Imai, Yo Horikawa, Kazuaki Ando, R. P. C. Janaka Rajapakse
Pages: 55 - 60
Previously, we have illustrated that the Histogram Matching based on Gaussian Distribution (HMGD) is an effective automated image processing method for obtaining a better feeling impression image. However, the simple HMGD works only for the image whose histogram has just one peak. For the image whose...

14. Moving Robots Lies and Their Minds with Degree of Confidence in a Decentralized Autonomous FMS

Hidehiko Yamamoto, Takayoshi Yamada, Shizuka Tanaka
Pages: 61 - 64
According to the previous study of a decentralized autonomous FMS using a mind, it is found that the production outputs decreased because an agent sometimes lies. To solve this problem, we study an AGV’s lie. The study is that AGVs recognize the lie that each AGV sends. To do this, we propose to give...
