Topographically directed, evaporation driven self-assembly (EDSA) of nanoparticles is a promising manufacturing technique that combines the control of top-down
This paper presents two data-based models for the measured time series of global annual average tropospheric temperatures. One model is a smoothing spline fit
The Federal Information Security Management Act of 2002 places significant requirements on federal agencies for the protection of information and information
The TREC Video Retrieval Evaluation (TRECvid) is an international benchmarking activity to encourage research in video information retrieval by providing a
Junctions using amorphous NbxSi1-x as a barrier have been developed for a wide range of possible applications. By co-sputtering the Nb and Si, both the relative
A nonparametric inferential statistical data analysis is presented. The utility of this method is demonstrated through analyzing results from minutiae exchange
A new correlation for two-phase flow pressure drop in 180? return bends is proposed based on a total of 241 experimental data points for R-22 and R-410A from
NIST s role in providing the optical radiation measurement science and standards to ensure the quality, accuracy, and comparability of our Nation s remote
We examine the effects of the rooftop environment on GPS time transfer, in particular the effects of multipath reflections from nearby metallic objects. Three
GPS carrier-phase frequency transfer (GPSCPFT) and two-way satellite time and frequency transfer (TWSTFT) were performed along three trans-Atlantic links over

We present measurements regarding the long-term frequency instability of NIST CSAC physics packages. Changes of the clock frequency are caused mainly through
The problem of signal integrity for GPS satellites is discussed. In particular, there is a need for characterizing peak deviation of GPS clocks from prediction

The Sistema Interamericano de Metrologia (SIM) consists of national metrology institutes (NMIs) located in all 34 member nations of the Organization of American
The ionosphere-free code (P3) GPS time transfer uses the dual-frequency measurements from GPS geodetic receivers to minimize the errors in the ionospheric delay

In this work, we describe radiometric platforms able to produce realistic spectral distributions and spatial scenes for the development of application-specific
The fingerprint datasets in many cases may exceed millions of samples. Thus, the needed size of a biometric evaluation test sample is an important issue in
Liquid agent transport was investigated around an unheated and heated cylinder (to a near-surface temperature of approximately 423 K) under ambient conditions
A compact Josephson voltage standard (CJVS) was constructed using a fixed microwave frequency at 76.76 GHz. The transportability of the CJVS makes in-situ JVS
