Software applications that successfully employ a grap ica user interface to display and manipulate their data are recognized as easy to use and difficult to implement. While the complexity of such applications has increased dramatically, the tools available to application designers have not advanced at the same pace. Current tools...
In this thesis the critical parameters involved in the
dislodgement and deformation of microbubbles in laminar
channel flow, are determined and evaluated. Experimentally
the effects of surface tension, viscosity, fluid flow rate,
density, and bubble diameter on bubble dislodgement were
evaluated. A theoretical scale analysis was performed which
provided a...
This thesis presents a control system for a walking
machine leg. The leg is representative of one of the six
legs required for a proposed walking machine based on the
geometry of the darkling beetle.
Each of the three joints is controlled by a DC servo
motor mounted to the...
The low thermal conductivity of gallium arsenide compared to silicon
results in self-heating effects in GaAs MESFETs that limit the electrical
performance of such devices for high power applications. To date, analytical
thermal models of self heating in GaAs MESFETs are based on the assumption
of a uniformly heated channel....
Since the industrial revolution, work and family
have been viewed as separate spheres, with women
relegated to the family sphere. With the advent of women
into the paid labor force, few studies have considered
the potentially complex context of women's work and
family experiences. The purpose of this study was...
Effective combustion of waste fuels requires an
understanding of the fuels characteristics. Gaseous and
particulate emissions, ash residues and combustion
properties are of interest to many; those that produce and
sell heating units, utilities interested in using the fuels
for power generation, regulatory agencies, municipalities
needing to solve a disposal...
