This paper presents a new approach to minimize the operation cost of wind-diesel system. Under the constraints of diesel units' startup/shut down time, ramp rate and power balance etc., the ‘Unit Commitment’ concept is introduced to construct the model for optimal operation planning of all...

In order to investigate the effect of temperature on the tensile strength of perforated Ti-6Al-4V (TC4) alloy, the tensile mechanical properties of TC4 alloy with various micro-hole array distributions were obtained at a temperature in a range from 20 o C to 500 o C by using a novel...

Murrayand Tsiatis (1996) described a weighted survival estimate thatincorporates prognostic time-dependent covariate informationto increase the efficiency of estimation. We propose a test statisticbased on the statistic of Pepe and Fleming (1989, 1991) thatincorporates these weighted survival...
