We consider the problem of dynamic load balancing in arbitrary (connected) networks on n nodes. Our load generation model is such that during each round, n tasks are generated on arbitrary nodes, and then (possibly after some balancing) one task is deleted from every nonempty node. Notice that this model fully saturates the resources of the network in the sense that we generate just as many new...

BACKGROUND We previously reported a new management variable, work rate, defined as work load due per hour, based on cumulative standard treatment times. We found that work rates were unachievable (ie, exceeded 1 hour of scheduled work per hour of available labor) for 75% of scheduled due times, despite presumed achievable average work load. OBJECTIVE To determine the optimal strategy for cre...

The aim of this research work was to investigate on the ball filling estimation of Miduk semi-autogenous (SAG) Mill via an utilized method. Miduk copper concentrator is located in Kerman Province, Iran, and its size reduction stage includes one gyratory crusher which feeds one SAG mill (9.75 dia.(m)*3.88 length(m)) following two parallel ball mills (5dia.(m)*7lenght(m)). After SAG mill, a tromm...
