Abstract: A method for scheduling workers in a business day. The method includes obtaining a scheduled worker distribution specifying an amount of work to be performed by the workers during a business day, where each worker is assigned a schedule within a work window, which includes a core component and a flex component. The method further includes obtaining a forecasted demand distribution for an amount of work to be performed by the workers during the business day and comparing the scheduled worker distribution with the forecasted demand distribution for the business day. The method further includes creating a new schedule for a worker when the scheduled worker distribution and the forecasted demand distribution are not substantially equal, where the new schedule is within the work window associated with the worker, and notifying, a predetermined amount of time in advance of the business day, the worker of the new schedule.

Abstract: An improved dome-shaped piston head is disclosed characterized by a plurality of channels, depressions, and recesses which enhance the flow of an air-fuel mixture around the piston head in a combustion chamber and the flow of exhaust gases from the chamber. Specifically, the dome-shaped head portion includes a pair of depressions in its intake and exhaust side portions for increasing swirl of the air-fuel mixture. The intake side portion of the piston head also includes first and second channels which cooperate with the intake depression to direct the incoming air-fuel mixture around the piston dome and upwardly into the combustion chamber with swirling turbulence. The exhaust side portion of the piston head includes a pair of tapered recesses on opposite sides of the exhaust depression for directing exhaust gases toward the exhaust opening.
