NON-LINEAR PSEUDORANDOM BIT GENERATION BY COMBINING BLUM BLUM SHUB AND LINEAR FEEDBACK SHIFT REGISTER SEQUENCES
… National Institute of Standards and Technology (NIST) statistical test suite. We identified lower bounds on the input parameters to increase the probability that the combiner would perform well under the NIST test suite. Our scheme produced consistently excellent results under NIST testing but is …

The Virginia Tech Calibration System
… National Institute of Standards and Technology (NIST) developed two PMU testing stands for steady-state conformance with the current standard and for dynamic performance testing. Since May 2010, Virginia Tech has been working closely with the NIST in developing a PMU testing system similar to the …

A Study on Energy Harvesters for Physical Unclonable Functions and Random Number Generation
… National Institute of Standards and Technology (NIST) Statistical Test Suite. The experiment results for the PUF generation are promising and indicate that the piezos are the better choice due to their stable frequency output. Each transducer was able to produce random numbers and pass the NIST …

Study on heat transfer to supercritical water in application to SMRs
… transfer using three correlations that relied on NIST REFPROP v.10 for thermophysical property values. The experimental inside-wall temperature and heat transfer coefficient profiles were stable while the selected correlations generated poor predictions. NIST REFPROP v.10 was investigated at the …
