Evaluating Feedback Systems for Residential Building Energy Monitoring

August 10, 2013
Author(s)
Wenqi Guo, Tania Ullah, MengChu Zhou
Rising global energy demand, increasing electricity prices, and the limitation of natural resources have led to increased interest in energy monitoring of residential buildings. Much research has been done to examine the effect of energy use feedback to

Theoretical Analysis of a Magnetophoresis-Diffusion T-Sensor Immunoassay

August 6, 2013
Author(s)
Thomas P. Forbes, Matt S. Munson, Samuel P. Forry
Microfluidic immunoassays have demonstrated broad application to the detection and quantification of analytes ranging from small drug molecules to large proteins and biomolecules. These systems exhibit short length scales, reduced sample volumes, and

Multi-resonant plasmonic nanodome arrays for label-free biosensing applications

July 10, 2013
Author(s)
Charles J. Choi, Stephen Semancik
The characteristics and utility of plasmonic nanodome arrays capable of supporting multiple resonance modes are described. A low-cost, large-area replica molding process is used to produce, on flexible plastic substrates, two-dimensional periodic arrays of

Distributed Coverage Optimization in a Network of Static and Mobile Sensors

June 17, 2013
Author(s)
Kamran Sayrafian, Hamid Mahboubi, Jalal Habibi, Amir Aghdam
This paper proposes efficient schemes to increase sensing coverage in a network composed of both mobile and static sensors. The proposed deployment techniques properly assign a virtual weight to every point in the sensing field, based on the information

MEMS Device for Fatigue Testing of 25 mm Thick Aluminum Specimens

June 13, 2013
Author(s)
Li-Anne Liew, David T. Read, Nicholas Barbosa
We report the development and demonstration of a MEMS test instrument to perform fatigue testing on 25 µm thick aluminum 1145 H19 foil. Both the foil material and the specimen fabrication were obtained from commercial sources, separate from the fabrication

Operation of gamma-ray microcalorimeters at elevated count rates using filters with constraints

May 15, 2013
Author(s)
Bradley K. Alpert, Robert D. Horansky, Douglas A. Bennett, William B. Doriese, Joseph W. Fowler, Andrew Hoover, Michael W. Rabin, Joel N. Ullom
We introduce a filter construction method for pulse processing that differs in two respects from that in standard optimal filtering, in which the average pulse shape and noise power spectral density are combined to create a convolution filter for

Experimental Study of the Thermal Impacts on Wireless Sensor Batteries

April 10, 2013
Author(s)
Wenqi Guo, William M. Healy, Mengchu Zhou
Wireless sensor networks are being considered for application within buildings to control various equipment in different working environments. As wireless sensors are powered by commercially available batteries, battery performance will directly affect the

Dynamic Key Refreshment for Smart Grid Mesh Network Security

February 24, 2013
Author(s)
Hamid Gharavi
This paper presents a dynamically updating key distribution strategy to enhance mesh network security against cyber attacks. The scheme has been applied to two security protocols known as Simultaneous Authentication of Equals (SAE) and Efficient Mesh

ITRS Chapter: MEMS

January 30, 2013
Author(s)
Michael Gaitan
The ITRS has organized a MEMS Technology Working Group (TWG), which has developed a new chapter on MEMS for its 2011 report. The report focuses on MEMS technologies associated with mobile Internet devices, such as smartphones and tablet computers. These

A titanium-nitride near-infrared kinetic inductance photon-counting detector and its anomalous electrodynamics

October 1, 2012
Author(s)
Martin O. Sandberg, Fabio C. da Silva, Kent D. Irwin, David P. Pappas, Sae Woo Nam, David Wisbey, Ben Mazin, Seth Meeker, Jonas Zmuidzinas, Henry G. Leduc
We demonstrate single-photon counting at 1550 nm with titanium-nitride (TiN) microwave kinetic inductancedetectors. Full-width-at-half-maximum energy resolution of 0.4 eV is achieved. 0-, 1-, 2- photon events are resolved and shown to follow Poisson
