In this paper, the linear fractional programming problem with interval coefficients in objective function is solved by the variable transformation. In this method a convex combination of the first and the last points of the intervals are used in place of the intervals and consequently the problem is reduced to a nonlinear programming problem. Finally, the nonlinear problem is transformed into a linear programming problem with two more constraints and one more variable compare to the initial problem. Numerical examples are illustrated to show the efficiency of the method.

Since the 1980s new techniques have appeared from which fuzzy logic have been applied extensively in medical systems. In this paper, Takagi-Sugeno-Kang [TSK] fuzzy control technique is used to regulate the blood glucose concentration level of a type I diabetes mellitus patient under an intensive insulin treatment in presence of the parameter variations and meal disturbance. The control algorithm incorporates expert knowledge about the treatment of this disease by using first order TSK type fuzzy logic controller to regulate the blood glucose level. The control scheme is based on closed-loop feedback strategy to overcome the variability in the glucose-insulin dynamics from patient to patient. Simulation results show that applying this controller improves very acute conditions of type I diabetic patient during proper time.

The object of this study is to determine the prevalence of most common Bacteria causing UTI and Antibiogram pattern respectively in Ahwas population. Materials & methods: In this retrospective descriptive study we gathered all urine culture results from lab centers. Results: From 48850 cases, 34360 (70.34%) and 14490 (29.66%) were females and males, respectively. The most frequent pathogens were E.coli (46.29%), S.saprophyticus (25.8%) and Klebsiella ...
