  • The objective of this study is to develop an algorithm in the consideration of importance Weight and desirable shape of specific department in the computerized layout planning. Quantitative relationship chart between each department was used. It is decided that the priority among the department as to variable factors and the optimum quantitative relationship chart was obtained using by the Weighting method. The algorithm presented in this study could generate more practical layout for the actual design problem.

  • In this paper, we propose a new method for the improvement of linearizing and adaptive convergence charateristics of the feedforward linear power amplifier. In this circuit, errors at the signal cancellation stage can be compensated at the error cancellation stage and the overall linearizaton and adaptation characteristics of the linear amplifier are improved. The broadband characteristics and linearizing capability are improved without increasing the complexity of circuits and the signal processing structure.

  • Fluid flow in LPG injector is delayed momently around nozzle and leaked accidentally, then engine operation becomes unstable. When attached cutsole injector that we can prevent fuel from leaking. Attaching additional devices cause loss of power and pressure. In this study, We has analyzed the performance of the LPG injector nozzle by changing cutsole geometry numerously by using Computational Fluid Dynamics.
