1. Neutral Networks-Based Adaptive Fixed-Time Consensus Tracking Control for Uncertain Multiple AUVs

Lin Zhao, Yingmin Jia, Jinpeng Yu
Pages: 179 - 182
This paper is concerned with the fixed-time consensus tracking problem for multi-AUV (autonomous underwater vehicle) systems with uncertain parameters and external disturbances. Firstly, a fixed-time terminal sliding mode is proposed, which can avoid the singularity problem. Then, a continuous distributed...

Hiromu Imaji, Kazushige Koiwai, Toru Yamamoto, Koji Ueda, Yoichiro Yamazaki
Pages: 195 - 200
In the construction field, the improvement of the work efficiency is one of important problems. However, the work efficiency using construction equipment depends on their operation skills. Thus, in order to increase the work efficiency, the operation skill is required to be quantitatively evaluated....

5. Containment Control for Nonlinear Multi-agent Systems with Parameter Uncertainties and Communication Delays

Ping Wang, Yingmin Jia
Pages: 201 - 204
This paper considers robust containment control problem for uncertain multi-agent systems with inherent nonlinear dynamics. A distributed protocol is proposed using local delayed state information, and then the original problem is converted into an H_∞ control problem by defining an appropriate controlled...

6. Parameter Estimation of a Skill Evaluation Model

Kazuo Kawada, Teruyuki Tamai, Toru Yamamoto
Pages: 205 - 208
In this study, the aim is to construct a "teacher-student model" for optimal skill acquisition. To support the optimal skill acquisition, modeling and estimation of an individual learning process are very important. The first-order system with time delay is introduced as an individual learning process...

7. Beacon-based tourist information system to identify visiting trends of tourists

Pages: 209 - 212
In this study, we propose a system that provides tourist information and obtains trends of visiting tourists using beacons and cloud service. As part of our research, we are working on the promotion of local area tourism in cooperation with a local community. A low energy Bluetooth device is used as...

8. Modeling and Simulation for a Quadrotor Vehicle With Adaptive Wing

Qunpo Liu, Hongqi Wang, Fuzhong Wang, Jikai Si, Naohiko Hanajima
Pages: 213 - 216
Aiming at developing high power efficiency system for quadrotor vehicle during height keeping and long distance flight, a quadrotor vehicle with adaptive wing is proposed. Angle of the wing respect to flying direction can be adjusted adaptively according to flying speed, to reduce energy expenditure...

9. Study On The Target Positioning For An Omni-Directional 3 DOF Mobile Manipulator Based On Machine Vision

Jiwu Wang, Yao Du, Wensheng Xu, Masanori Sugisaka
Pages: 217 - 220
The omni-directional mobile robot with multi DOF, because the operation posture and operation accuracy of the manipulator can be better controlled in a narrow or crowded workplace compared with the general manipulator, is getting more interested in practical applications. The present problem is to improve...

10. Analyzing Multiple Narrative Structures of Kabuki based on the Frameworks of Narrative Generation Systems

Takashi Ogata
Pages: 221 - 226
Although kabuki is a genre of, so to speak, traditional performing arts, it also has many of the characteristics of a contemporary genre, including such various elements as narrative, drama, dance, and music. This analysis and study will contribute to the design and development of studies on digital-narrative...

11. Informational Narratology and Automated Content Generation

Takashi Ogata, Yoji Kawamura, Akihito Kanai
Pages: 227 - 233
Several studies have proposed a concept called "informational narratology" or "information narratology." In this paper, we integrate narratological studies, including narratology and various literary theories, into information technologies, such as artificial intelligence and cognitive science, in order...
