Error Free Liquid Flow Diverters for Calibration Facilities (FEDSM2002-31085)

January 1, 2002
Author(s)
Tsyh Tyan Yeh, Aaron N. Johnson, Pedro I. Espina, N Yende
A design for diverter valves in gravimetric liquid flow calibration facilities is proposed. The concept makes use of repeated unidirectional motions of the diverter valve to reduce errors associated with asymmetry in the diverter valve motion and in the

Excitonic Effects on Optical Second-Harmonic Polarizabilities of Semiconductors

January 1, 2002

E K. Chang, Zachary H. Levine, Eric L. Shirley
We present an ab initio many-body formalism for computing the frequency-dependent second-harmonic polarizability of semiconductor materials that includes both local-field and excitonic effects. We calculate the second-harmonic polarizability for AIP, AIAs

Experimental Study of a Water Droplet Impinging on a Liquid Surface

January 1, 2002
Author(s)
Samuel L. Manzello, Jiann C. Yang
An experimental study is presented for water droplet impingement on a liquid surface. The impaction process was recorded using a high-speed digital camera at 1000 frames per second. The initial droplet diameter was fixed at 3.1 mm 0.1 mm and all

Fiber and Component Metrology for High-Speed Communications

January 1, 2002
Author(s)
Tracy S. Clement, Paul D. Hale, Paul A. Williams
Increased data rates require improved measurements. We give specific guidance to avoid measurement pitfalls in two critical high data rate areas: Polarization-mode dispersion and transmitter/receiver frequency response. For audiences familiar (not expert)
