  • Foreign tourists prefer a T-shirts as a souvenir and it can be used practically. The objective of this study is to development T-shirts design using traditional window frame pattern for tourism souvenir. T-shirts design applied traditional window-frame pattern, which is a geometrical figure among traditional shapes. The results are as follows. 1. Window-frame pattern were general shape and complicated shape. 2. Window-frame pattern is visually ordered and stabled because has perfect ratio. 3. Geometrical line of window-frame applied on a T-shirt and match with modern sense.

  • This paper demonstrates that the recurrent neural networks can be used successfully for the identification of finite automata (FAs). A new type of recurrent neural network (RNN) is proposed and the offline training algorithm, regulated Levenberg-Marquadt (LM) algorithm, for the network is developed. Simulation result shows that the identification and the extraction of FAs are practically achievable.

  • Due to the inherent complexity in the CIM operation, achieving the triple, meeting duedates, maximizing machine utilization, and maximizing system throughput simultaneously is practically impossible. Targeting the small-to-medium size industries of Korea, we propose an exrert system that 'provides a good and practical solution to the CIM operation problems. Heavy consideration has given to the real-time and dynamic nature of CIM in the development process of the system. The system is under testing stage at KU-FMS, model CIM plant.

  • A control law for a SCARA robot manipulator is designed using recursive torque methods. This scheme uses previous torques and error dynamics to generate torque controls at the present time and adopts relatively simple numerical and control algorithms that can be easily realizable. In order to evaluate the performance and robustness of the suggested control system, the 2-link SCARA robot manipulator is practically implemented using a dSPACE interface. It is found that the recursive controller has a good tracking performance in spite of the presence of payload disturbances.
