Automotive emission is becoming a critical threat to today's human health. Many researchers are studying engine designs leading to less fuel consumption. Gearbox selection plays a key role in an engine design. In this study, Taguchi quality engineering method is employed, and optimum gear ratios...

In order to increase the welfare of society through the implementation of a building energy-performance standard, a method is required by which the least-cost means of obtaining the desired space conditioning of a building can be estimated. In other words, a life-cycle cost model must be...

This study determines the extent to which it is possible to develop monetary estimates of the marginal social cost of fuels, using natural gas to test a methodology that could be applied to other fuels. This requires review of previous estimates of both market and nonmarket costs to the extent...
