Demand Reduction and Inefficiency in Multi-Unit Auctions
Multi-Unit Auctions Demand Reduction Treasury Auctions Electricity Auctions
2015/9/18
Auctions often involve the sale of many related goods: Treasury, spectrum, and electricity auctions
are examples. In multi-unit auctions, bids for marginal units may affect payments for inframarginal...
EFFECTS AND PERFORMANCE OF SPECKLE NOISE REDUCTION FILTERS ON ACTIVE RADAR AND SAR IMAGES
RADAR SAR Images Noise Speckle Filtering Adaptive Filter
2015/8/17
Reduction of speckle noise is one of the most important processes to increase the quality of radar coherent images. Image variances
or speckle is a granular noise that inherently exists in and degra...
QE Reduction due to Pixel Vignetting in CMOS Image Sensors
CMOS imager scaling QE vignetting
2015/8/17
CMOS image sensor designers take advantage of technology scaling either by reducing pixel size or by adding more transistors to the pixel. In both cases, the distance from the chip surface to the phot...
