Temporal Range Registration for Unmanned Ground and Aerial Vehicles

November 30, 2005
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this article for registering 8 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured 9 environments. We are primarily motivated by the development of 3D

Towards the Design of Effective Formative Test Reports

November 30, 2005
Author(s)
Mary F. Theofanos, Whitney Quesenbery
Many usability practitioners conduct most of their usability evaluations to improve a product during its design and development. We call these "formative" evaluations to distinguish them from "summative" (validation) usability tests at the end of

Self-Assembly, Molecular Ordering, and Charge Mobility in Solution-Processed Ultrathin Oligothiophene Films

November 29, 2005
Author(s)
A R. Murphy, Paul C. Chang, Priscilla VanDyke, J Liu, J M. Frechet, V Subramanian, Dean DeLongchamp, S Sambasivan, Daniel A. Fischer, Eric K. Lin
Symmetrical quarter-(T4), penta-(T5), sexi-(T6), and heptathiophene (T7) oligomers containing thermally removable aliphatic ester solubilizing groups were synthesized, and their UV-vis and thermal characteristics were compared. Spun-cast thin films of each

Characterization of Carbon Nanotube Purity Using a Quartz Sensor Platform

November 28, 2005
Author(s)
Stephanie A. Hooker, Ryan Schilt, Natalia Varaksa, John H. Lehman, Paul Rice
Carbon nanotubes are revolutionary materials, with properties that are vastly different than any other bulk form of carbon. Their unique combination of electrical, mechanical, and thermal properties makes them attractive for applications in advanced

Electrical and Spectroscopic Characterization of Metal/Monolayer/Si Devices

November 24, 2005
Author(s)
Curt A. Richter, Christina A. Hacker, Lee J. Richter
A simple technique for vibrational spectroscopy of metal/monolayer/silicon structures is applied to study the interaction of Au, Al, and Ti with alkane monolayers, either assembled onto thin oxides or directly attached to Si. The results are correlated

Josephson junctions with nearly superconducting metal silicide barriers

November 23, 2005
Author(s)
Yonuk Chong, Nicolas Hadacek, Paul Dresselhaus, Charles J. Burroughs, Burm Baek, Samuel Benz
We present a detailed study of the electrical properties of Nb-based planar Josephson junctions with superconducting metal silicide barriers, TiSi2 and WSi2. While these non-hysteretic junctions are useful for voltage standard applications, they are also

Effect of Nitrogen on Band Alignment in HfSiON Gate Dielectrics

November 22, 2005
Author(s)
Safak Sayan, Nhan V. Nguyen, James R. Ehrstein, James J. Chambers, Mark R. Visokay, Manuel Quevedo-Lopez, Luigi Colombo, T Yoder, Igor Levin, Daniel Fischer, M Paunescu, Ozgur Celik, Eric Garfunkel
We have studied the band alignment of HfSiO and HfSiON films by soft x-ray photoemission (SXPS), oxygen K-edge x-ray absorption (XAS), and spectroscopic ellipsometry. Nitridation of HfSiO reduced the band gap by 1.50+- 0.05eV and the valence and conduction

Report of the Working Group on Crystal Phase Identifiers 2005-3-21

November 20, 2005
Author(s)
David R Brown, Sidney Abrahams, Michael Berndt, John Faber, Vicky L. Karen, Sam Motherwell, Jean-Claude Toledano, Pierre Villars, John Westbrook, Brian McMahon
The International Union of Pure and Applied Chemistry (IUPAC) has been examining standards for the electronic representation of chemical information, and as part of this effort it has established a working group in conjunction with the USA National
