Nonresonant Control of Multimode Molecular Wave Packets at Room Temperature

January 1, 2002
Author(s)
R A. Bartels, T C. Weinacht, S R. Leone, H C. Kapteyn, M M. Murnane
We demonstrate the creation and measurement of shaped multimode vibrational wave packets in CCl 4 for the first time. Impulsive Raman excitation of wave packets allows coherent control techniques to be applied to molecules without passing through an

On the Mitigation of Early Age Cracking

January 1, 2002
Author(s)
Dale P. Bentz, M R. Geiker, O M. Jensen
Potential means of limiting early age cracking ofconcrete structures have been investigated. Threedifferent methods of mitigating autogenous strainsand stresses in cement mortars (w/s=0.35, 8 % silica fume) are compared: 1.) reduction of thesurface tension

Optical Fiber Current and Voltage Sensors for the Electric Power Industry

January 1, 2002
Author(s)
Allen Rose, Gordon W. Day
The research and development of fiber current and voltage sensing for the power utilities is reviewed. A brief history of the work on these sensors and a description of the physical effects used is also given. The chapter is divided into polarimetric and

Optical Frequency Standards and Measurements

Optical Reflectance of Metallic Coatings: Effect of Aluminum Flake Orientation

January 1, 2002
Author(s)
B Laurenti, Egon Marx, Maria Nadal, M E. McKnight, L Sung
The orientation of platelet-like pigments in coatings is affected by the processing conditions resulting in appearance variations of the final product. A set of aluminum-flake pigmented coatings having different flake orientations was pre-pared using
