In this paper, we propose a novel robust fault isolation filter design method using the left eigenstructure assignment scheme proposed by the authors. The proposed method guarantees that the ${\gamma}$ simultaneous faults can be isolated when the number of available outpur measurements is ${\gamma}$. Moreover, if there exist redundant output measurements, the eigenvaluses of te filter system can be assigned to the desired position or the filter can be designed robustly to, the system parameter variation. Liu & Si developed a filter design method which has the same purpose, fault isolation. However their method cannot use the redundant freedom of the output matrix C. The proposed filter can use the redundant freedom of the matrix C effectively. Beside this in this paper, an eigenstructure assignment methodology that satisfies the required fault isolation conditions is also proposed. The proposed fault isolation filter was applied for isolating the simultaneous faults to a VTOL aircraft in order to verify the fault isolation performance.

In these studies, the relationship of the thyroid function of normal and unilateral thyroidectomized rabbit, were st studied. $I^{131}$ uptake rate of the thyroid gland, the concentration of the $PBI^{131}$ and $I^{131}$ in the blood, erum $PBI^{131}$ conversion ratio, and the thyroidal $I^{131}$ release rate in ten rabbits were mesured following a single intramuscular injection of $10{\mu}ci$ of $I^{131}$. 1. The thyroidal $I^{131}$ uptake rate in the treated group were 5.06, 8.58, 6.46, and 6.54% in 12, 36, 60 and 85 hrs., respectively, after injection of $I^{(3)}$. The uptake rate were significantly differrenciate between the two groups. (P<0.05) 2. The $PBI^{(3)}$ conversion ratios were 9.87, 15.63, 41.01, 66.25 and 66.25% in 12, 36, 132, 180 hrs., respectively, after injection of $I^{131}$. No significant difference was observed between the groups. 3. The concentration of $PBI^{131}$ and $I^{131}$ in the blood were significant between the groups. 4. The excretion rate of $I^{131}$ in urine was not significant between two groups, but the excretion of $I^{131}$ in the treated group was higher than that of the control group. 5. The exrcetion rate of $I^{131}$ in feces in the treated group were significantly higher than the control group. (p<0.01)
