An open area of research in complex systems is to move reliability and failure assessments earlier in the engineering design process. When compared to later design, early decisions are cost effective and have a large impact on the system. Standard methods are limited by the availability of data and often...
This describes the development of a new fuel flowmeter. Among the desired features were an accuracy of ±2%, a linear response to fuel flow rate, a means of increasing the sensitivity at the low end of the meter scale and portability so that it would be equally useful in the...
The compressive behavior of continuous fiber composites is not as well
understood as their tensile behavior because research and industrial applications have until
recently focused on the latter. Furthermore, most theoretical and experimental studies on
the compression of composites have examined the case of unidirectional specimens with
fibers along the...
"Piping Design and Engineering" first published in 1963 by
Grinnell, Co. is widely used by engineers to perform approximate
thermal stress analysis of high-temperature piping systems. The
text consists of numerical constants to calculate end reactions and
maximum bending stresses in a variety of piping configurations from
known properties of...
The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...
An experimental study was made of the average and turbulent
wind characteristics of the flow over a model of a coastal headland.
The scale of the model was 300:1, corresponding to a prototype size
of 500 m.
The data for validation of the model study was obtained from
instruments mounted...
A model is developed that allows the prediction of the stress-strain
distribution in a mixed carbide sphere pac fuel pin during
irradiation. The model is coupled with a previously developed model
for the thermal behavior of the pin. The one-dimensional (radial at
various axial locations) solution is for quasi-steady pin...
This thesis is an engineering report on the creep behavior of
power transmission line conductors. Laboratory creep test results
are reported for Pheasant, Narcissus and Chukar conductors.
The report follows a standard nomenclature and format suggested
by the International Study Committee No. 6 of Conference
Internationale des Grands Reseaux Electriques...
Bipedal locomotion is a complex phenomenon to understand and control, making it difficult for legged robots to achieve the speed, agility, efficiency, and robustness of their animal counterparts. This thesis argues for the use of numerical optimization to investigate and implement bipedal control as it applies to biology, dynamical models,...
Sprawled-posture insects exhibit a remarkable ability to rapidly run in a stable manner
over complex terrain, a feat that has yet to be equaled by man-made legged robots.
Recent experimental results suggest that these insects may employ a hierarchical
control structure, in which locomotion performance emerges from a combination of...
