Parallel detection and elimination of strongly connected components for radiation transport sweeps
(Texas A&M University, 2001)
Discrete ordinate methods are commonly used to simulate radiation transport for fire or weapons modeling. The computation proceeds by sweeping the flux across a grid. A particular cell cannot be computed until all the ...
Navigation in the ancient Eastern Mediterranean
(Texas A&M University, 2001)
Studies on ancient navigation have traditionally derived their information from ancient geographers and the authors of various periploi ("sailings around"), a type of coast-pilot written in and after the fifth century B.C. ...
Validation of Pisum sativum agglutinin fluorescent marker for stallion spermatozoal acrosomes with transmission electron microscopy
(Texas A&M University, 2001)
This study was designed to validate the use of a pea lectin to assess changes in acrosomal integrity of equine spermatozoa. The optimal conditions for the induction of the acrosome reaction were determined using ejaculates ...
The static and dynamic characteristics of divergent tapered-bore hole-pattern gas seals
(Texas A&M University, 2001)
Experimental data is presented for three hole-pattern annular gas seals with differing diverging tapers machined in them. The holes are approximately 3.12 mm (.123 in) deep on average with a hole area to surface area ratio ...
Optimization of cutting parameters in end milling using tool life as an objective function
(Texas A&M University, 2001)
In any manufacturing industry there is a constant urge to improve upon existing conditions, a concept the Japanese aptly term Kaizen. Improvements are essentially a steppingstone to increased profit margin, better quality ...
Effect of shrink fits on threshold speeds of rotordynamic instability
(Texas A&M University, 2001)
An investigation of the effect of shrink fits on threshold speeds of rotordynamic instability has been performed. It is known that running rotors at supercritical speed can result in some rotordynamic problems (asynchronous ...
Dynamics of mechanisms with elastic bodies
(Texas A&M University, 2001)
Belt drive mechanisms are alternatives to robotic actuators to obtain complex repetitive motions by simple actuation. By simply changing the dimensions of the mechanism, we can obtain different kinds of trajectories for ...
20 MHz IF bandpass switched capacitor [] modulator using a high performance OTA with NCFF compensation scheme
(Texas A&M University, 2001)
Switched capacitor (SC) circuits are widely used in many applications because of their accuracy and ease of integration in CMOS technology. They are not suitable for operation in high frequencies because of the settling ...
Experimental studies of steam-propane injection to enhance recovery of an intermediate crude oil
(Texas A&M University, 2001)
In the past few years, research has been conducted at Texas A&M University on steam-propane injection to enhance oil recovery from the Morichal field, Venezuela, which contains 13.5 ⁰API gravity oil. Experimental results ...
Realistic fault modeling and quality test generation of combined delay faults
(Texas A&M University, 2001)
With increasing operating speed and shrinking technology, timing defects in integrated circuits are becoming increasingly important. The well established stuck-at-fault model is not sufficient because it is a static fault ...
