North American Environmental Compliance Attitudes Towards Electronics

September 27, 2007
Author(s)
Krista Botsford, John V. Messina, Eric D. Simmon
More and more countries are beginning eco-compliance legislation for electronics products. Where does the USA stand? This paper will discuss the following areas and attitudes towards environmental compliance in the USA: levels of legislation, who is (or

Biomimetic Superhydrophobic Surfaces: Multiscale Approach

September 26, 2007
Author(s)
Michael Nosonovsky
Micro- and macro-droplet evaporation and condensation upon micropatterned superhydrophobic surfaces built of flattop pillars are investigated with the use of Environmental Scanning Electron Microscope. It is shown that the contact angle hysteresis depends

NIST Special Publication 250-79 Airspeed Calibration Service.

September 26, 2007
Author(s)
Tsyh Tyan Yeh, J. M. Hall
The National Institute of Standards and Technology (NIST) provides calibration services for airspeed instrumentation such as Pitot-static tubes, anemometers (ultrasonic, thermal or hot-wire, cup, and propeller types) as well as others. The NIST calibration

System-Level Pre-Launch Calibration of Onboard Solar Diffusers

September 26, 2007
Author(s)
R Barnes, Steven W. Brown, Keith R. Lykke, Gerald T. Fraser, James J. Butler
Onboard diffuse reflecting plaques are carried to orbit as radiometric reference standards for Earth-observing satellite instruments. For many instruments the reflectance properties of the plaque are characterized independent of the instrument, and the

Spring constant calibration of AFM cantilevers with a piezosensor transfer standard

September 24, 2007
Author(s)
Eric Langlois, Gordon A. Shaw, John A. Kramar, Jon R. Pratt, Donna C. Hurley
We describe a method to calibrate the spring constants of cantilevers for atomic force microscopy (AFM). The method makes use of a piezosensor comprised of a piezoresistive cantilever and accompanying electronics. The piezosensor was calibrated before use

Transport quantum logic gates for trapped ions

September 21, 2007
Author(s)
Dietrich G. Leibfried, Emanuel H. Knill, Christian Ospelkaus, David J. Wineland
Many efforts are currently underway to build a device capable of large scale quantum information processing (QIP). While QIP has been demonstrated for a few qubits in several systems, severe difficulties have to be overcome in order to construct a large

Evaluating a Ranging Protocol For 3D Imaging Systems

September 19, 2007
Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Alan M. Lytle
In 2006, the ASTM E57 committee was established to develop standards for 3D imaging systems. A 3D imaging system is a non-contact instrument that is used to measure the range and bearing to and/or the 3D coordinates of points on an object or within a

Feasibility of Using a Concrete Mixing Truck as a Rheometer(Orlando, Florida)

September 19, 2007
Author(s)
Chiara F. Ferraris, Roy Cooley, Joe Grein, Max A. Peltz, Michael Topputo, Steve Verdino
The goal of the tests reported here was to further determine the feasibility of using a concrete mixing truck as a rotational rheometer. This work is the continuation of preliminary tests [ , ] that seemed to indicated that the yield stress and the plastic

Simplified motional heating rate measurements of trapped ions

September 19, 2007
Author(s)
Ryan Epstein, Signe Seidelin, Dietrich G. Leibfried, Janus Wesenberg, John J. Bollinger, Jason Amini, Brad R. Blakestad, Joseph W. Britton, Jonathan Home, Wayne M. Itano, John D. Jost, Emanuel H. Knill, C. Langer, R. Ozeri, Nobuyasu Shiga, David J. Wineland
We measure motional heating rates of trapped atomic ions, a factor that influences multi-ion quantum logic gate fidelities. Two simplified techniques are developed for this purpose: one relies on Raman sideband detection implemented with a single laser

Guided Data Capture (GDC) 5.0

September 17, 2007
Author(s)
Vladimir Diky, Robert D. Chirico, Robert N. Goldberg, Michael D. Frenkel
Guided Data Capture (GDC) 5.0 includes capture capabilities for biochemical substances and selected biothermodynamic properties. A key characteristic of data capture for much biothermodynamic data arises from the need to fully specify relatively complex
