The 2012 IEEE-RAS Safety, Security and Rescue Robotics Summer School

November 8, 2012
Author(s)
Raymond Sheh, Haldun Komsuoglu, Adam Jacoff, Tetsuya Kimura, Daniele Nardi, Johannes Pellenz, Gerald Steinbauer
The 2012 IEEE Robotics and Automation Society Safety, Security and Rescue Robotics Summer School was held from the 9th to the 15th of September in Alanya, Turkey, and brought together a select group of students, researchers, responders, manufacturers and

EVALUATING METHODS OF SHIPPING THIN SILICON WAFERS FOR 3D STACKED APPLICATIONS

November 7, 2012
Author(s)
Richard A. Allen, Urmi Ray, Vidhya Ramachandran, Iqbal Ali, David T. Read, Andreas Fehk?hrer, J?rgen Burggraf
An experiment was performed to develop a method for choosing appropriate packaging for shipping 300 mm silicon wafers thinned to 100 µm or less for three-dimensional stacked integrated circuits (3DS-ICs). 3DS-ICs hold the promise of improved performance

Nanoscale Reference Materials for Environmental, Health, and Safety Measurements: Needs, Gaps, and Opportunities

November 7, 2012
Author(s)
Aleksandr B. Stefaniak, Vincent A. Hackley, Gert Roebben, Kensei Ehara, Steve Hankin, Michael T. Postek, Iseult Lynch, Wei-En Fu, Thomas P. Linsinger, Andreas Th?nemann
There is a need to understand and manage potential risks posed to workers, the public, and the environment from exposure to engineered nanomaterials. In response, several organizations have developed lists of relevant nano-objects and of physico-chemical

Structural Association of Nonsteroidal Anti-Inflammatory Drugs with Lipid Membranes

November 7, 2012
Author(s)
Mohan Babu Boggara, Mihaela Mihailescu, Ramanan Krishnamoorti
The location and distribution of ibuprofen, a model nonsteroidal anti-inflammatory drug, in a phospholipid bilayer was examined in molecular detail by a combination of neutron diffraction and computer simulations. In addition to their use as antipyretic

Class Numbers via 3-Isogenies and Elliptic Surfaces

November 6, 2012
Author(s)
Cam McLeman, Dustin Moody
We show that a character sum attached to a family of 3-isogenies defi ned on the fibers of a certain elliptic surface over Fp relates to the class number of the quadratic imaginary number field Q(\sqrtp}). In this sense, this provides a higher-dimensional

Reduction Formulae for Products of Theta Functions

November 6, 2012
Author(s)
Peter L. Walker
In four cases it is already known that the product of two distinct Jacobian theta functions having the same variable z and the same nome q is a multiple of a single Jacobian theta function, with the multiple independent of z. The main purpose of the

Two dimensional spectroscopic imaging of individual ferromagnetic nanostripes

November 6, 2012
Author(s)
Han-Jong H. Chia, Feng Guo, Lyubov Belova, Robert McMichael
We use ferromagnetic resonance force microscopy (FMRFM) to spectroscopically image the edge modes in individual 700 and 400 nm wide Permalloy stripes with a spatial resolution on the order of 200 nm. The imaging clearly identi es some resonances as edge

Dual-channel, single-photon upconversion detector near 1300 nm

November 5, 2012
Author(s)
Paulina S. Kuo, Jason S. Pelc, Oliver T. Slattery, Martin M. Fejer, Xiao Tang
Upconversion of 1.3-micron photons and detection using silicon avalanche photodiodes (Si APDs) can produce high photon detection efficiencies (PDEs) with low dark count rates. We demonstrate a novel two-channel device based on a phase-modulated

On Distributed Energy Routing Protocols in the Smart Grid

November 5, 2012
Author(s)
Jie Lin, Guobin Xu, David W. Griffith, Xinyu Yang, Wei Yu
The Smart Grid is a new type of power grid that will provide reliable, secure, and efficient energy transmission and distribution. It promises to integrate distributed energy resources with conventional generation plants, and intelligently transmit energy

A Stochastic and Local Theory of Fatigue for Aging Pressure Vessels and Piping

November 4, 2012
Author(s)
Jeffrey T. Fong, Nathanael A. Heckert, James J. Filliben
We begin with a review of the fatigue design methodology for new pressure vessels and piping, based on both deterministic and stochastic approaches. We will then prove that the same methodology for estimating the remaining life of aging pressure vessels

Long Range Internal Stresses in Single-Phase Crystalline Materials

November 2, 2012
Author(s)
Mike Kassner, Peter Geantil, Lyle E. Levine
Backstresses, or long range internal stresses (LRIS), have been suggested by many to exist in plastically deformed crystalline materials. Elevated stresses may be present in regions of elevated dislocation density or dislocation heterogeneities in the

(001) FePt Graded Media with PtMn Underlayers

November 1, 2012
Author(s)
Chao-Chien Chiang, Wu-Chang Tsai, Liang-Wei Wang, Hao-Cheng Hou, Jung-Wei Liao, Hong-Ji Lin, Fan-Hsiu Chang, Brian Kirby, Chih-Huang Lai
(001)-oriented FePt graded media are obtained by using PtMn underlayers. The PtMn underlayer does not only behave as the (001) structural template, but provides the diffusion source of Mn. The diffusion of Mn into FePt reduces its anisotropy but, on the

An Improved Antenna Gain Extrapolation Measurement

November 1, 2012
Author(s)
Jason B. Coder, David R. Novotny, Jeffrey R. Guerrieri, Michael H. Francis, Brian C. Stillwell
An improved antenna gain extrapolation measurement is proposed. The improved method consists of a vector network analyzer, a pair of RF optical links, and a pair of waveguide mixers. We present a detailed description of the new extrapolation measurement
