Chemistry and Structure of Hydration Products

August 1, 1999
Author(s)
Paul E. Stutzman
This chapter covers papers published and abstracted in 1996 relating to cement hydration and the chemistry and structure of hydration products.

Road Detection and Tracking for Autonomous Mobile Robots

April 5, 2002
Author(s)
Tommy Chang, Tsai Hong Hong, Michael O. Shneier, C E. Rasmussen
As part of the Army's Demo III project, a sensor-based system has been developed to identify roads and to enable a mobile robot to drive along them. A ladar sensor, which produces range images, and a color camera are used in conjunction to locate the road

A Low-Power, High-Sensitivity Micromachined Optical Magnetometer

December 11, 2012
Author(s)
Rahul R. Mhaskar, Svenja A. Knappe, John E. Kitching
We demonstrate a fiber-optically coupled optical magnetometer based on a microfabricated 87Rb vapor cell in a micromachined silicon sensor head. The cell is optically heated with light at 1.5 mm brought to the cell through an optical fiber and absorbed by

Connector-induced offsets in optical fiber power meters

August 20, 2006
Author(s)
Igor Vayshenker, Xiaoyu X. Li, Darryl A. Keenan
We discuss issues related to calibration of optical fiber power meters. The power readings may vary when using various types of fiber connectors, or even the same type of connectors made by different vendors. We study the connector effects by calibrating

The Fast Fourier Transform for Experimentalists Part II: Convolutions

August 1, 2005
Author(s)
D Donnelly, Bert W. Rust
The discrete Fourier transform (DFT) is a widely used tool for the analysis of measured time series data. The Cooley-Tukey fast Fourier transform (FFT) algorithm gives an extremely fast and efficient implementation of the DFT. This is the first of a series
