This paper describes a cost model developed to assess the cost ramifications of the transition from tinlead to lead-free electronic parts. All tin-lead, all lead-free and mixed assembly approaches are considered. The model makes basic assumptions of a fixed generic set of applications, incorporates a cost of plan development, and includes the costs of reprocessing tin lead to lead free and vice...

This problem lends itself to further exploration of fundamental mechanisms and concepts such as time-out, multicast, consensus, and failure detector. We will survey recent theoretical results of studies related to agreement problems and show how system engineers can use this information to gain deeper insight into the challenges th...

Our laboratory was interested in epidemiological and toxicological findings from aircraft-assisted pilot suicides. Between 1993-2002 there were 3,648 fatal aviation accidents. The NTSB determined that 16 were aircraft-assisted suicides; 15 from intentional crashing of an aircraft and 1 from exiting the aircraft while in-flight. All pilots involved in these aircraft-assisted suicides were male, ...

materials exhibit significant creep behavior at temperatures above 40% of their absolute melt temperature. lead, tin and their alloys are such materials which experience significant creep behavior in room temperature. one of the most important applications of the tin-lead alloys is soldering electronic circuits in electronic industry, and for lead are isolation walls and wet batteries. room tem...

The use of driving simulators in clinical trials is an interesting new development for testing the effects of drugs on impairment. Medscape interviewed Gary G. Kay, PhD, Associate Professor, Department of Neurology, Georgetown University School of Medicine and President, Cognitive Research Corporation, concerning his company's simulator -the CRC MiniSimTM – and how it is being used in clinical ...

This paper investigates the impact of setup cost reduction on an inventory policy for a continuous review mixture inventory model involving controllable backorder rate and variable lead time with a service level constraint, in which the order quantity, setup cost, and lead time are decision variables. Our objective is to develop an algorithm to determine the optimal order quantity, setup cost, ...
