Effect Of Temperature on The Absorption Loss Of Chalcogenide Glass Fibers
(Optical Society of America, 1999)
The change in the absorption loss of IR-transmitting chalcogenide glass fibers in the temperature range? of -90 degrees C less than or equal to T less than or equal to 70 degrees C was investigated. For sulfur-based glass ...
Visibility-Dependent Depth Of Focus For Incoherent Sinusoidal Sources
(Optical Society of America, 1992-05-01)
A visibility-dependent depth of focus is developed for incoherent sinusoidal sources. This analysis is based on a derived relationship between the visibility and the optical transfer function (OTF). The formalism developed ...
Active suppression of acoustic radiation from impulsively excited structures
(Acoustical Society of America, 1991-12-01)
The objective is to use active control to suppress the acoustic energy that is radiated to the far field from a structure that has been excited by a short-duration pulse. The problem is constrained by the assumption that ...
On the evanescent fields and the causality of the focus wave modes
(AIP Publishing, 1995-08-01)
The diverging and converging field components of the source-free focus wave modes are studied within the framework of both the Whittaker and Weyl plane wave expansions, It is shown that, in the Weyl picture, the evanescent ...
Notch Spatial Filtering with an Acousto-Optic Modulator
(Optical Society of America, 1998)
The role of acousto-optic (AO) modulators in programmable real-time image processing has recently been demonstrated. For fully investigating the image-processing capabilities of the AO modulator, general techniques to ...
Transient Flow Of Thermotropic Liquid-Crystalline Polymers in Step Strain Experiments
(AIP Publishing, 1990-07-01)
The transient response of two thermotropic liquid crystalline polymers (a copolyester of 60 mol_% p_hydroxybenzoic acid, PHB, and 40 mol_% poly(ethylene terephthalate), PET, and a copolyester of PHB and 2_hydroxy_6_naphthoic ...
Order Preserving Minimal Perfect Hash Functions and Information Retrieval
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1991), TR-91-01
Rapid access to information is essential for a wide variety of retrieval systems and applications. Hashing has long been used when the fastest possible direct search is desired, but is generally not appropriate when ...
An Operation Model Supporting the Generation of Requirements That Capture Customer Intent
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1999-11-01), TR-99-05
Product quality is a direct reflection of how well it meets the cutomer's needs. Hence, the ability to capture customer requirements correctly and succinctly is paramount. Unfortunately, within software development frameworks ...
Remote Usability Evaluation at a Glance
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1997-07-01), TR-97-12
Much traditional user interface evaluation is conducted in usability laboratories, where a small number of selected users is directly observed by trained evaluators. However, as the network itself and the remote work ...
Who Reuses What? C++ Libraries and Programmer's Traits
(Department of Computer Science, Virginia Polytechnic Institute & State University, 1994-05-01), TR-94-18
Software Reuse is one key to increasing productivity within the software development process. By reusing existing software, time and effort are saved in the coding, testing, and maintenance phases of a software product. ...
