Effects of Long-Term Creep on the Integrity of Modern Wood Structures
(Virginia Tech, 1996-12-10)
Short-term creep tests in tension and in compression were conducted on southern pine, Douglas-fir, yellow-poplar, and Parallamâ ¢ samples at temperatures ranging between 20 and 80Â° C and at 6, 9 and 12% moisture content. ...
Development of a Hypermedia Template Using Whole Language Instructional Methods for the Preservation of Native American Languages
(Virginia Tech, 1996-03-01)
This developmental study addresses the problem of Native American language loss through the development of a new instructional model to teach indigenous languages to Native American learners. Whole ...
Characterization of Electrochemical Interfaces by INfrared Spectroscopy
(Virginia Tech, 1996-08-30)
The properties of electrochemical interfaces are studied using Fourier transform infrared spectroscopy. Potential difference infrared spectroscopy (PDIRS) was used in the investigation of carbon monoxide adsorbed on ...
Analysis and Reduction of Moire Patterns in Scanned Halftone Pictures
(Virginia Tech, 1996-05-01)
In this dissertation we provide a comprehensive theory for the formation of a moire pattern in a sampled halftone image. We explore techniques for restoring a sampled halftone image with a moire ...
Influence of the Interphase on the Mechanical Properties of Nylon 66 Composites
(Virginia Tech, 1996-08-01)
The mechanical properties of glass fiber and carbon fiber reinforced nylon 66 were investigated using both microscopic and macroscopic testing techniques. The objective was to determine how different interphase morphologies ...
Parallelization of the Euler Equations on Unstructured Grids
(Virginia Tech, 1996-05-01)
Several different time-integration algorithms for the Euler equations are investigated on two distributed-memory parallel computers using an explicit message-passing paradigm: these are classic Euler Explicit, four-stage ...
Interaction of Cognitive Style and Learner Control of Presentation Mode in a Hypermedia Environment
(Virginia Tech, 1996-07-18)
Educational hypermedia has been heralded as providing instruction that accommodates learners' individual differences, allowing them to learn in accordance with their unique needs, desires, and preferences. Advocates of ...
Video Technology and the Subjective Norm, Perceived Behavioral Control, and Attitudes Toward Physical Activity of Middle School Students: Does P.E.TV make a difference?
(Virginia Tech, 1996-04-01)
This study examined the effects of Physical Education Television (P.E.TV) on 69 southwest Virginia middle school students' subjective norm, perceived behavioral control, and attitudes toward ...
Behavior and modeling of partially restrained beam-girder connections
(Virginia Tech, 1996)
An Investigation of Software Metrics Affect on Cobol Program Reliability
(Virginia Tech, 1996-06-20)
The purpose of this research was to predict a COBOL program's reliability from software characteristics that are found in the program's source code. The first step was to select factors based on the human information ...
