INCOME AS A WORE GENERAL OPTIMIZATION CRITERION AS REGARDS AVAILABILITY AND REPLACEMENT COSTS IN DETERMINING THE OPTIMAL PERIOD OF PREVENTIVE REPLACEMENT

This paper discusses a procedure for determining the optimal period of preventive replacement of elements with increasing failure rate when the criterion is income per operating time unit.It is shown that income per operating time unit and its complementary value of the sum of losses due to system dwell and replacement costs represent more general

Studies with adult fish print mens pink polo shirt musicians show that beginning lessons before age seven is associated with better performance on musical tasks and enhancement in auditory and motor brain regions.It is hypothesized that early training interacts with periods of heightened neural development to promote greater plasticity and better l
