The Performance of Essential Facilities in Superstorm Sandy

April 4, 2014
Author(s)
Therese P. McAllister
Superstorm Sandy affected the functionality of a number of essential buildings and facilities in the flooded areas of New York and New Jersey. The flood elevations exceeded design-level floods in many locations, as defined by FIRM maps and codes and

Robustness Assessment of RC Frame Buildings under Column Loss Scenarios

April 3, 2014
Author(s)
Yihai Bao, Joseph A. Main, Hai S. Lew, Fahim Sadek
A computational assessment of the robustness of reinforced concrete (RC) building structures under column loss scenarios is presented. A reduced-order modeling approach is presented for three-dimensional RC framing systems, including the floor slab, and

Robustness of Precast Concrete Frames: Experimental and Computational Studies

April 3, 2014
Author(s)
Joseph A. Main, Yihai Bao, Hai S. Lew, Fahim Sadek
This paper describes both full-scale testing and detailed finite-element modeling of a precast concrete moment-frame assembly extracted from the perimeter moment frame of a 10-story prototype building. The assembly comprises two beam spans and three

Superconformal Copper Electrodeposition in Complexed Alkaline Electrolyte

April 3, 2014
Author(s)
Daniel Josell, Thomas P. Moffat
This paper examines superconformal filling of trenches during copper electrodeposition from alkaline cupric tartrate electrolyte. Extreme bottom-up filling of submicrometer damascene trenches with minimal deposition on the sidewalls and the field around

Optical volumetric inspection of sub-20 nm patterned defects with wafer noise

April 2, 2014
Author(s)
Bryan M. Barnes, Francois R. Goasmat, Martin Y. Sohn, Hui Zhou, Richard M. Silver, Andras Vladar, Abraham Arceo
We have previously introduced a new data analysis method that more thoroughly utilizes scattered optical intensity data collected during defect inspection using bright-field microscopy. This volumetric approach allows conversion of focus resolved 2-D

Advances in source technology for focused ion beam instruments

April 1, 2014
Author(s)
Noel Smith, John Notte, Adam V. Steele
Owing to the development of new ion source technology, users of focused ion beams (FIBs) have an increasingly wide array of uniquely capable platforms to choose from. Specifically, the new ion sources are able to offer superior performance in several

An Empirical Comparison of Combinatorial and Random Testing

April 1, 2014
Author(s)
Laleh Ghandehari, Jacek Czerwonka, Yu Lei, Soheil Shafiee, Raghu N. Kacker, D. Richard Kuhn
Some conflicting results have been reported on the comparison between t-way combinatorial testing and random testing. In this paper, we report a new study that applies t-way and random testing to the Siemens suite. In particular, we investigate the

Assessment of Conformity, Decision Rules and Risk Analysis

April 1, 2014
Author(s)
Steven D. Phillips, Michael Krystek
Measurement uncertainty has important economic consequences for calibration and inspection activities. In calibration reports, the magnitude of the uncertainty is often taken as an indication of the quality of the laboratory. In industrial measurements

Calibrating multiple microscopes with a smartphone

April 1, 2014
Author(s)
Peter Bajcsy, Mary C. Brady, Jacob Siegel
Summary: The iPhone liquid crystal displays allows efficient and accurate calibration of an inexpensive array of handheld microscopes for measuring microscopic dynamic events over a large field of view. How does one build an inexpensive array of handheld

CO 2 -Responsive Microemulsions Based on Reactive Ionic Liquids

April 1, 2014
Author(s)
Paul Brown, Matthew John Wasbrough, Burcu E. Gurkan, T. Alan Hatton
We demonstrate that the nanodomains within a ternary system consisting of oil, surfactant and a new reactive ionic liquid can be tuned reversibly upon exposure to and removal of CO 2 under mild conditions of temperature and pressure. The equilibrium

Color Error in the Digital Camera Image Capture Process

April 1, 2014
Author(s)
John Penczek, Paul A. Boynton, Jolene Splett
The color error of images taken by digital cameras is evaluated with respect to its sensitivity to the image capture conditions. A parametric study was conducted to investigate the dependence of image color error on camera technology, illumination spectra

Decision-Theoretic Aspects of Meta-Analysis

April 1, 2014
Author(s)
Andrew L. Rukhin
In the random-effects model of meta-analysis a canonical representation of the restricted likelihood function is obtained. The relationship between the common mean estimators and the heterogeneity variance estimators is explored via this representation. An

Establishing an upper bound on contact resistivity of ohmic contacts to n-GaN nanowires

April 1, 2014
Author(s)
Paul T. Blanchard, Kristine A. Bertness, Todd E. Harvey, Norman A. Sanford
Contact resistivity ρ c is an important figure of merit in evaluating and improving the performance of electronic and optoelectronic devices. Due to the small size, unique morphology, and uncertain transport properties of semiconductor nanowires (NWs)

Estimating Fault Detection Effectiveness

April 1, 2014
Author(s)
David R. Kuhn, Raghu N. Kacker, Yu Lei
[Poster] A t-way covering array can detect t-way faults, however they generally include other combinations beyond t-way as well. For example, a particular test set of all 5-way combinations is shown capable of detecting all seeded faults in a test program
