Present day data processing technology requires very high speed signal processing and data conversion rates. One such application which requires high speed is switched capacitor circuits used in Sigma-Delta modulators. A major active component of switched capacitor circuits is the monolithic operational amplifier(opamp). Because of the relatively poor speed performance...
The objectives of this research were to evaluate the
behavior of actual metal-plate-connected (MPC) tension-splice
and heel wood truss joints under seismic loads from the
Northridge earthquake (tension-splice joints only) and under
loads from a large artificial earthquake (1.0 g's and 0.67
g's maximum horizontal and vertical accelerations,
respectively). A...
The objective of this research was to evaluate the duration of load factor for
metal-plate-connected (MPC) truss joints subjected to various cyclic loading conditions.
Heel and tension-splice joints from a standard 30-foot span Fink truss constructed from
nominal 2x4 Douglas-fir lumber were tested. A testing frame similar to that developed...
In recent years, there has been an extensive effort to develop low-cost implementations
of radio frequency integrated circuits for consumer applications. This thesis is a
research effort in the design and implementation of integrated RF CMOS Power Amplifiers
(PAs). A significant challenge in the implementation of RF CMOS ICs is...
This study re-examines how variations in market power
across industries affect the relative number of females and
males hired in a given occupation. The study builds upon
similar work done by Sharon Oster (1975) to examine the female
to male wage differences. Both market power and human capital
factors such...
The torsion test was evaluated as a method for determining the shear
strength of full-size structural lumber. The evaluation involved an experimental
length study, an experimental depth study, and a finite element study.
The length study consisted of fifty nominal 2x4 specimens, ten specimens
for each length, and ten American...
A commercially available, three-dimensional finite-element analysis software was used to model the load-displacement
behavior of metal-plate-connected (MPC) joints in wooden trusses. Model features included consideration
of material properties, teeth-to-grain-to-direction-of-force orientation, wood-to-wood interaction, and gaps between wood
members. To simulate wood-to-plate interaction, the main feature of the model, each tooth of...
