Variable rate CELP speech coding using widely variable parameter updates
(Texas A&M University, 1995)
Code-excited, linear prediction (CELP) has become an accepted method for low bit rate, high quality coding of digital speech. The success of fixed rate CELP schemes has led to increased interest in variable rate techniques ...
Stress analysis and failure of the bond interface of a metal matrix component
(Texas A&M University, 1995)
A two dimensional orthotropic thermoelastic finite element algorithm is developed herein, and it is used to evaluate the performance of a metal matrix composite (MMC) structural component provided by G.E. and Battelle Labs. ...
Smoke and toxic species analyses from controlled combustion of wood impregnated with guayule resin
(Texas A&M University, 1995)
Dominant commercial treatments currently used for wood preservation are pentachlorophenols (PCP), creosote, and chromium copper arsenicals. These wood preservatives present many studied and documented environmental and ...
Effect of low pO2 and host plant on colonization of roots by Pseudomonas putida PH6 (L1019)
(Texas A&M University, 1995)
Effective use of genetically altered microorganisms to enhance growth requires a full understanding of the factors governing their colonization potential, as well as survival in soil. A low oxygen concentration is known ...
A manual procedure for assembly sequence planning based on the exploded view method
(Texas A&M University, 1995)
This thesis covers the development of a manual planning procedure based on the computerized method of exploded views to generate an optimal or near-optimal assembly sequence. Care has been taken to minimize iterative and ...
Revised estimates of electron absorbed fractions and radionuclide S-values in trabecular bone
(Texas A&M University, 1995)
The field of nuclear medicine has reached advanced stages in the use of radiopharmaceuticals for the treatment and diagnosis of innumerable maladies. However, along with the use of nuclear medicine come responsibilities ...
Growth of New Guinea impatiens under no-leach drip irrigation
(Texas A&M University, 1995)
New Guinea impatiens (Impatiens Xhawkerii Barbados') were grown under drip irrigation with the aid of microtensiometers. There were two irrigation regimes (leach and no leach) and three fertility rates (6-1.5-2, 12-3-4, ...
A computational study of ultrasonic film thickness measurements in annular two-phase flows under microgravity conditions
(Texas A&M University, 1995)
An ultrasonic system has previously been proposed to measure interfacial characteristics of annular two-phase flows in reduced acceleration environments. A computational model based on ray tracing is developed to predict ...
A 3D laser doppler velocimetry study of the upstream velocity profile effects upon the flow field inside an orifice flowmeter
(Texas A&M University, 1995)
Orifice meters are used for the measurement of flow rate, particularly in the natural gas industry. They are relatively simple and inexpensive devices; the flow rate is calculated by observing the pressure drop across an ...
A test rig for the identification of rotordynamic coefficients of fluid film bearings
(Texas A&M University, 1995)
A test rig and measurement procedure to identify the rotordynamic coefficients of generic fluid film bearing elements are described. The test apparatus allows the exchange of test articles without modifications to the basic ...
