An experimental method to increase sediment supply to a salt marsh in subsidence dominated environments
(Texas A&M University, 2007-09-17)
This thesis examines the environmental conditions which led to the loss of 90%
of the natural salt marsh in Galveston Island State Park since 1930 and analyzes one
potential method to reduce future loss. Available data and ...
Development of Models for Series and Parallel Fan Variable Air Volume Terminal Units
(Texas A&M University, 2007-09-17)
Empirical models of airflow output and power consumption were developed for
series and parallel fan powered variable air volume terminal units at typical design
pressure conditions. A testing procedure and experimental ...
Reynolds and Favre-averaged rapid distortion theory for compressible, ideal-gas turbulence
(Texas A&M University, 2007-09-17)
Compressible ideal-gas turbulence subjected to homogeneous shear is investigated
at the rapid distortion limit. Specific issues addressed are (i) the interaction
between kinetic and internal energies and role of ...
Low power architecture and circuit techniques for high boost wideband Gm-C filters
(Texas A&M University, 2007-09-17)
With the current trend towards integration and higher data rates, read channel
design needs to incorporate significant boost for a wider signal bandwidth. This
dissertation explores the analog design problems associated ...
Experiments to examine transplant procedures on the seagrass Halodule beaudettei
(Texas A&M University, 2007-09-17)
During the growing seasons of 1999 and 2000 five experiments were performed to
test growth of the seagrass Halodule beaudettei (shoal-grass) in nursery pond conditions.
Sediment oxidation state, sediment source, container ...
Design and implementation of a frequency synthesizer for an IEEE 802.15.4/Zigbee transceiver
(Texas A&M University, 2007-09-17)
The frequency synthesizer, which performs the main role of carrier generation
for the down-conversion/up-conversion operations, is a key building block in radio
transceiver front-ends. The design of a synthesizer for a 2.4 ...
Impacts of a conspicuity treatment on speed limit compliance
(Texas A&M University, 2007-09-17)
In reduced speed zones, where no other cues indicate the need to slow down, drivers sometimes fail to notice the standard Speed Limit sign and may be speeding inadvertently. To help reduce inadvertent speeding, a red ...
Evaluation of the heterotic potential of sorghum [Sorghum bicolor (L.) Moench] adapted to the southern Africa region
(Texas A&M University, 2007-04-25)
Sorghum [Sorghum bicolor (L.) Moench] production in Africa is widespread with low yields due to low inputs and the lack of sorghum hybrids. This situation has forced most of these farmers to grow maize hybrids since they ...
Behavior and movement of southern right whales: effects of boats and swimmers
(Texas A&M University, 2007-09-17)
Guidelines for sustainable swim-with tourism for large whales are not welldeveloped,
as researchers have focused on delphinids. Nations that signed the
Convention on Biological Diversity at the Earth Summit in Rio de Janeiro ...
Development of an improved methodology to assess potential unconventional gas resources in North America
(Texas A&M University, 2007-09-17)
Since the 1970s, various private and governmental agencies have conducted studies to
assess potential unconventional gas resources, particularly those resources contained in
tight sands, fractured shales, and coal beds. ...
