Loop shaping of structural dynamics
(Texas A&M University, 1999)
Dynamic response of a stature can be characterized by mass, stiffness, and damping. Design of a conventional structure is primarily based on stiffness characteristics because damping is assumed to be negligible. Although ...
Direct comparison of Neural Network, Fuzzy Logic and Model Prediction Variable Structure vortex flow controllers
(Texas A&M University, 1999)
Current fighter aircraft are required to be maneuverable and agile at high angles of attack. Limited control power available at these extreme flight conditions prompts the need to use control augmentation techniques. The ...
Application of graphical method in analyzing falling weight deflectometer (FWD) data
(Texas A&M University, 1999)
Deflection measurements have long been used to evaluate the structural capacity of in-situ flexible pavements. The structural evaluation of flexible pavements is recently carried out mostly with the Falling Weight Deflectometer ...
Simulation of surface waves with porous boundaries in a 2-D numerical wave tank
(Texas A&M University, 1999)
The classical water wave theories for use in coastal and offshore design have had the theoretical drawback of assuming a rigid, nonporous bottom overlain by an inviscid fluid. In most offshore areas not far from the shore, ...
Numerical simulations of supercell interactions with thermal boundaries
(Texas A&M University, 1999)
The association of tornadoes and tornadic thunderstorms with surface boundaries has been recognized for several decades. However, little has been done to study this phenomenon in a systematic manner. This study uses a ...
Symplectic integrators for trajectory simulations
(Texas A&M University, 1999)
For Hamiltonians separable in the form H = T + V, the method of Creutz and Gocksch is used to construct even-order integrative that will preserve the invariants of motion. Several of these symplectic integrators of the ...
A genetic and molecular analysis of the Drosophila dachs gene
(Texas A&M University, 1999)
The proximal-distal (P-D) axis is one of the three major body axes and is responsible for limb formation. Development in the Drosophila P-D axis is the least understood of the three axes due to historical and technical ...
Is the Texas Agricultural Extension Service succeeding at educating and satisfying Texas agricultural producers?
(Texas A&M University, 1999)
The Texas Agricultural Extension Service Rangeland Ecology and Management Program Unit (TAEX-RLEM) initiated the Rangeland Resource Survey in 1997 to evaluate the success of the Unit in educating and satisfying Texas ...
Absorption of chromium and reduction of chromate by subterranean clover
(Texas A&M University, 1999)
In order to optimize phytoremediation techniques, it is important to first understand the plant physiological processes associated with enhanced absorption and translocation of the target metal in the plant. The emphasis ...
Physiological response of Kemp's ridley sea turtles (Lepidochelys kempii) to entanglement net capture
(Texas A&M University, 1999)
Kemp's ridley sea turtles (Lepidochelys kempii) were captured in entanglement nets near Sabine Pass, Tx/La, during May through August, 1996 and 1997. Serial blood samples were collected to: 1) identify physiological effects ...
