We analyze a minimum number of vertices of a complete graph that can be decomposed into one factor of diameter 2 and k factors of diameter at most 3. We find exact values for k ≤ 4 and the asymptotic value of the ratio of this number and k when k tends to infinity. We also find the asymptotic value of the ratio of the number of vertices of the smallest complete graph that can be decomposed into p factors of diameter 2 and k factors of diameter 3 and number k when p is fixed.

We present results on numerical regulator design for sampled-data nonlinear plants via their approximate discrete-time plant models. The regulator design is based on an approximate discrete-time plant model and is carried out either via an infinite horizon optimization problem or via a finite horizon with terminal cost optimization problem. In both cases, we discuss situations when the sampling period T and the integration period h used in obtaining the approximate discrete-time plant model are the same or they are independent of each other. We show that, using this approach, practical and/or semiglobal stability of the exact discrete-time model is achieved under appropriate conditions.

Work results of the gynecology-obstetrics clinic Sarajevo maternity ward have been shown. Number of deliveries reached 3289, which iz significantly less then in the year 200. Prematurity reached 6.6%. Cesarian Sections were carried out in 19.3% cases and this represents a remarkable increase in comparison with the previous year 2000, when it reached 16.8%. Perinatal mortality iz 11.1@1000. Perinatal mortality shows a decrease in comparison with the period before the war. Late fetal mortality has not been significantly changed. Neonatal mortality shows an apparent decrease. Total perinatal mortality of mature newborns iz 6.9@1000 and has a constant tendency to decrease, reaching 10.5@1000 in 1991. Clinical presentation of deceased newborns predominantly presents with respiratory distress syndrome.
