  • Generally, The modeling method for the mathematical model is mdeled by using the physical laws and the system identification. In this paper, The arago's disk system of the operating principle of induction motors is selected as an example for identification. The system transfer function is derived from input/output data through experiment. Model is estimated by using ARX, ARMAX, BJ, OE model structure and compared each other.

  • The $^{99m}Tc-phosphate$ compounds, of which methylene diphosphonate is most widely used, were originally introduced as bone scanning agents intended primarily to detect metastatic bone deposit. They may also accumulate in extraskeletal sites including breast. Recently we had the opportunity to observe one case of cystosarcoma phyllodes that was confirmed by tissue biopsy and demonstrated diffuse extraskeletal uptake of $^{99m}Tc-MDP$ in the breast on $^{99m}Tc-MDP$ bone scan in the breast on $^{99m}Tc-MDP$ bone scan. So we present this case with the brief review of literatures.
