Kouhei Nishimura, Yasunari Yoshitomi, Taro Asada, Masayoshi Tabuse
Pages: 93 - 96
We developed a secure communication method using a discrete wavelet transform. Two users must each have a copy of the same piece of music to be able to communicate with each other. The message receiver can produce audio data similar to the sending user's speech by using our previously proposed method...

5. Research on SVG Control Method Under Unbalanced Conditions

Zheng Zheng, Yousong Zhou, Guopeng Zhang
Pages: 97 - 100
In order to reduce the complexity of traditional methods, a PCI (Proportional Complex Integral) controller is adopted to control SVG under unbalance-grid condition, which has better performance than PI controller to eliminate steady-state error to compensate nonlinear loads. Based on the •• frame, the...

Yi Li, Yingmin Jia, Jianheng Ling
Pages: 101 - 104
In this paper, a catapult separation device equipped with guide mechanism is considered, and the corresponding dynamic model is descripted firstly. Then, employing the dynamic simulation software ADAMS, the virtual prototype model of the separation device is established, and the whole process of on-orbit...

7. Optimizing the Motion for Robotic Snap Assembly Using FEM

Peihao Shi, Kensuke Harada, Weiwei Wan, Ixchel G. Ramirez, Juan Rojas, Hiromu Onda
Pages: 105 - 109
In this paper, we aim to provide a better assembly method for a snap joints assembly task. We create a 3D cellphone model and use ADAMS simulation environment to analyze the relative motion between screen and backer part. We focus on two points in this research. 1) Two kinds of relative motion between...

8. Self-repairing Adaptive PID Control for Plants with Sensor Failures

Masanori Takahashi
Pages: 110 - 113
This paper presents a new design method for a self-repairing adaptive PID control system. The control system has the adaptive adjusting mechanisms for the PID gains, and also can detect the sensor failure by self-test using the integrator in the PID controller. Hence, for plants with unknown parameters,...

9. RETUSS: Ensuring Traceability System between Class Diagram in UML and Java Source Code in Real Time

Tetsuro Katayama, Keisuke Mori, Yoshihiro Kita, Hisaaki Yamaba, Kentaro Aburada, Naonobu Okazaki
Pages: 114 - 117
Ensuring of the traceability of deliverables is one of effective methods to secure the quality of software. It can verify that the requirements are reflected in the programs. But it has two problems: taking much labor and time, and causing mistakes by human handling. This paper has implemented RETUSS...

10. Tracking/Robust Trade-off Design of a Sampled-data PID Controller for Second-order Plus Dead-time Systems

Pages: 118 - 121
In this paper, we propose a new design method of a second-order plus dead-time (SOPDT) sampled-data Proportional-Integral-Derivative (PID) control system, where the continuous-time plant is controlled using the discrete-time controller. The proposed control system is designed so that the tracking performance...

11. Genetic Algorithm-Based Technique and Tool for Generating Mutants of Extended Place/Transition Nets

Tomohiko Takagi, Shogo Morimoto
Pages: 122 - 127
An EPN (Extended Place/transition Net) is used as a formal model that represents the behavior of software. When mutation testing is performed based on the EPN, failures are intentionally inserted into an original EPN (EPN that represents the expected behavior of software) in order to create mutant EPNs....

Yasuhiro Suzuki, Rie Taniguchi
Pages: 128 - 130
Molecule Robotics have been realized by using bio molecules such as DNA, proteins, for example in Molecular Robotics Research Project [2012-17, JSPS]; bio molecules, such as DNA or proteins are highly structured and they already have a kind of “intelligence” and adapt to environment change. Hence, we...
