Probabilistic analysis of foundation forces for a class of unbalanced rotating machines
(1980)
This dissertation considers the problem of the foundation force of an unbalanced rotating machine from both deterministic and probabilistic viewpoints. The rotor-housing is modeled as a three degree-of-freedom system wherein ...
Turbulent heat/mass transfer enhancement with V-shaped ribs in a square channel
(1992)
This dissertation presents a comprehensive experimental investigation of the effects of V-shaped ribs on the heat transfer enhancement and the increased pressure drop for turbulent air flow in a square channel. The test ...
Condensation of a new alternative refrigerant flowing inside horizontal smooth tubes
(1994)
An experimental and analytical investigation of forced convective condensation in smooth circular tubes is performed for R-22 and R32+R125 mixture (50% by mass). The refrigerant is condensed by water inside a 0.315 inch ...
Development of a transient heat and mass transfer model of residential attics to predict energy savings produced by the use of radiant barriers
(1992)
A transient heat and mass transfer model was developed to predict ceiling heat gain/loss through the attic space in residences and to accurately estimate savings in cooling and heating loads produced by the use of radiant ...
Understanding molecular and macroscopic relaxation processes in model epoxy resins : theoretical and practical aspects
(1994)
In the previous phase o f this research project completely phase separated and partially phase separated bimodal epoxy resins were prepared by incorporating a 22,500 weight average molecular weight advanced epoxy resin ...
Improved analysis of laminated heterogeneous beams and associated formulation of a new finite element method
(1988)
Kirchhoff's theory for plates and Bernouilli-Euler's theory for beams ignore the effects of transverse shear and normal deformations on stresses and displacements. Various subsequent theories have incorporated these effects ...
An elastohydrodynamic investigation of time dependent pumping ring operation
(1973)
This research is a theoretical investigation of the transient operation of a fluid-mechanical device known as a pumping ring. The purpose of this device is to pump small amounts of fluid from a lower to a higher pressure ...
An H formulation of the QFT approach to robust performance under significant uncertainties
(1994)
The main problem investigated in this research deals with the synthesis of controllers for achieving a desired robust performance in the presence of significant plant uncertainties. The robust performance problem is ...
Criterion for failure under reversed transverse shear superimposed upon static tension
(1974)
A stress testing machine was designed and built to study the combined effect of mean static stress and reversed shear stress on the fatigue life of a material. Aluminum alloy 7075-T6 was tested under different combinations ...
A new objective function for robot calibration
(1994)
When using a robot, the operator usually desires to locate the tool accurately. To accomplish this, the operator should measure the tool position then use feedback to "drive" the manipulator in such a way that the tool ...
