A method for fabricating a semiconductor device includes providing a substrate having a bulb-type recessed region, forming a gate insulating layer over the bulb-type recessed region and the substrate, and forming a gate conductive layer over the gate insulating layer. An optimization engine object may have a plurality of dependent objects including at least a dependent optimization engine object, or at least one of a supply-side or demand-side object. In other exemplary embodiments of the invention, the triggered events include transaction-oriented events, entertainment events, and events associated with enhancements to human ability or function.
