Details of the 1998 Watt Balance Experiment Determining the Planck Constant

The National Institute of Standards and Technology (NIST) watt balance experiment completed a determination of Planck constant in 1998 with a relative standard uncertainty of 87 × 10(-9) (k = 1), concurrently with an upper limit on the drift rate of the SI kilogram mass standard. A number of other fundamental physical constants with uncertainties dominated by this result are also calculated. Th...

Materials. The PEDOT:PSS (Clevios PH 1000, 1 wt%) aqueous dispersion was purchased from Heraeus. Waterborne polyurethane (PU) was provided by DSM (China). Poly(dimethylsiloxane) (PDMS, Sylgard 184, Dow Corning) prepolymer was prepared by mixing base silicone gel with a curing agent in a 10:1 weight ratio. Dimethyl sulfoxide (DMSO) was purchased from Aladdin Chemistry Co., Ltd., Shanghai, China....

dyebias.application.subset Return a subset of reporters that can be dye bias-corrected reasonably well Description Convenience function returning a subset of reporters that can be expected to be corrected reasonably well. Often, the logical AND of this set and that of maW(data.norm) == 1.0 is used. The resulting subset is passed as the application.subset-argument to dyebias.apply.correction. Ar...

I describe the challenges involved in designing and evaluating high assurance, verifiable voting systems. I describe the Pret a Voter scheme that provides voterverifiablity with minimal trust in officials, software etc. I also describe a number of threats against voting schemes and the extent to which they apply to the basic Pret a Voter scheme. Some enhancements to the scheme designed to count...
