Understanding the U.S. National Standards System

June 1, 2002
Author(s)
K J. Johnsen
This article, intended for publication in German in Germany, clarifies attributes of the U.S.standards system and its similarities and differences with European and international counterparts. In the United States, standardization is essentially a free

W. Thomsen, G Vallone, F Vetrano, P Villoresi, W von Klitzing, P Wolf, Nan Yu, M.S. Zhan
The proposed mission \Space Atomic Gravity Explorer (SAGE) has the scientifi c objective to investigate gravitational waves, dark matter, and other fundamental aspects of gravity as well as the connection between gravitational physics and quantum physics

Metrology of Microstructured Waveguides for Spintronic Applications

July 30, 2010
Author(s)
SangHyun S. Lim, Atif A. Imtiaz, Dazhen Gu, Pavel Kabos, Thomas Mitchell (Mitch) Wallis
Patterned permallay films as a part of a coplanar waveguide (CPW) were fabricated, and the magnetization dynamics of such structures was investigated as fundamental building blocks for magnetic spintronic devices. Anisotropic magneto-resistance (AMR)

Quantum Computing

January 28, 2010
Author(s)
Emanuel H. Knill
Imagine a computer that can exploit quantum mechanics to solve previously intractable problems in physics, mathematics and cryptography. Such a quantum computer would revolutionize computing technology while teaching us about fundamental physics and ways

On the 60 mV/dec @300 K Limit for MOSFET Subthreshold Swing

April 26, 2010
Author(s)
Kin P. Cheung
The 60 mV/dec limit for subthreshold swing at 300K is generally considered a fundamental limit that cannot be defeated. The physical origin of this limit is revisited in this paper and the fact that this limit is in part determined by the density-ofstates

Multiparameter Equations of State for Selected Siloxanes

April 25, 2006
Author(s)
P. Colonna, R. Nannan, A. Guardone, Eric Lemmon
The development of technical equations of state using the 12-parameter Span-Wagner functional form for four siloxanes is presented in two parts. The fluids under investigation include hexamethyldisiloxane (MM), tetradecamethylhexasiloxane (MD4M)

A Microelectromechanically Controlled Cavity Optomechanical Sensing System

July 17, 2012
Author(s)
Houxun H. Miao, Kartik A. Srinivasan, Vladimir A. Aksyuk
Microelectromechanical systems (MEMS) have been applied to many measurement problems in physics, chemistry, biology and medicine. In parallel, cavity optomechanical systems have achieved quantum-limited displacement sensitivity and ground state cooling of

Phase noise suppression in frequency comb generators

June 2, 2010
Author(s)
Craig W. Nelson, Archita Hati, J F. Nava-garcia, David A. Howe
We propose an idea to suppress the flicker (1/f) noise in radio frequency (RF) multiplier based frequency comb generators. Comb generators are often used for frequency multiplication in frequency synthesis. In general, comb generators apply high power to a

January 1, 2001
Author(s)
Randolph Elmquist, Marvin E. Cage, Yi-hua D. Tang, Anne-Marie Jeffery, Joseph R. Kinard Jr., Ronald F. Dziuba, Nile M. Oldham, Edwin R. Williams
This paper describes some of the major contributions to metrology and physics made by the NIST Electricity Division, which has existed since 1901. It was one of the six original divisions of the National Bureau of Standards. The Electricity Division

A Comparative Study of CMM Flat-Surface Inspection Plans

July 1, 1992
Author(s)
J Hsu, T Hsu, James J. Filliben, Ted Hopp
This document reports on the findings from a collaborative effort by J. P. Hsu of the University of Texas at El Paso, T. W. Hsu (also of the same affiliation), James J. Filliben of the Statistical Engineering Division of the National Institute of Standards

Measuring the permittivity tensor of anisotropic DyScO3 to 110 GHz
