Measurements Of Young's Modulus Of Elasticity Of The Canine Aorta With Ultrasound, D J. Hughes, Charles F. Babbs, L A. Geddes, J D. Bourland

Weldon School of Biomedical Engineering Faculty Publications

We have developed an ultrasonic technique for determining the dynamic Young's modulus of elasticity (E) of the canine aorta in vivo. Young's modulus was measured in the descending thoracic aorta (DTA) and the abdominal aorta (AA) of 12 dogs over a range of mean blood pressures from 40-200 mmHg. The vessels were excised and dynamic moduli were determined in vitro postmortem from pressure-volume curves. The data so obtained were compared to the in vivo values. In vivo and in vitro moduli increased exponentially with mean distending pressure (P). The equation of best fit for these data was of the form …

Replacing Farm Machinery, R Crossman

Journal of the Department of Agriculture, Western Australia, Series 4

In talking of machinery replacement it seems implied that the replacement items of plant are bigger and therefore better than their predecessers. It is also implied that plant replacement is becoming more costly.

Before any decision to replace machinery, the reason for replacement should be carefully considered.

There may be alternatives to the bigger and better solution.

Options For Machinery And Labour, A F. Herbert

Journal of the Department of Agriculture, Western Australia, Series 4

Machinery is one of the highest costs in farming today. It is not unusual for capital investment in machinery to be 20 to 30 percent of the total investment in the farm.

On an annual basis, expenditure directly attributable to machinery can be 40 per cent or more.

This article cannon be a panacea for everyone to reduce machinery costs - each farm is different. But some of the issues might be of help.

The Effects Of A Kinesthetic Training Program On The Acquisition Of Industrial Skills Among University Students, John V. Mockler

Dissertations and Theses @ UNI

Training workers for specific jobs is receiving much attention in industry. The demand for skilled workers is increasing constantly and as this happens newer and more efficient methods of training are sought In the psychomotor/sensory area. skills that appear to offer a wide amount of transferability are those dealing with fine sensitivity, manual dexterity, and coordination. Even though these skills lend themselves well to training, this area is somewhat deficient in current educational and training programs (Sjogren, 1977, p.23). Presently, on-the-job training is widely used for training workers in the actual tasks they will perform during their job.

The Relationship Between Teacher Sex Role Models And Career Aspirations Of High School Industrial Arts Students, Janet Lynn Robb

Dissertations and Theses @ UNI

Sex role stereotyping has been the focus of a number of research projects trying to determine just where stereotyping lies and ways to eliminate it. Although most of the research points toward role modeling as a major cause, little has been done to test that theory.

The purpose of this study was to determine the relationship between teacher sex role models and the career aspirations of students enrolled in high school industrial arts courses throughout the United States. This study was limited to tenth, eleventh, and twelfth grade students enrolled in industrial arts programs in high schools in the United …

An Instrument For Determination Of The Polarization Of Fluorescence, George Irwin Johnston

Dissertations and Theses

This thesis is concerned with the development of a compact, sensitive and reliable instrument for determination of the polarization of fluorescence of fluorescein tagged molecules in solution. The instrument as designed and constructed differs from others (2,3,4,5,6,8,9). The difference is that all of its optical system is aligned on a single axis. This was accomplished by the use of an ellipsoidal mirror positioned between the excitation source and the phototube fluorescence signal receiver. In addition, the excitation source, a 45 watt tungsten-iodide light was electronically regulated to control the intensity.

Two types of determinations were made to verify the performance …

Complete Elastic-Plastic Solution Around A Tensile Crack In Strain-Hardening Materials, Clancy Hatleberg

Mechanical Engineering ETDs

A complete elastic-plastic solution for both small and large scale yielding is found for the total stress field surrounding a tensile crack in an infinite sheet of strain-hardening materials under conditions of plane stress. The solution is based on the deformation theory of plasticity in conjunction with strain-hardening stress-strain relations, and is found by using the minimum of a modified complimentary energy principle coupled with a modified Ritz method. Numerical results are obtained for two approximate constitutive laws; a Ramberg-Osgood stress-strain relation and a modified Ramberg-Osgood stress-strain relation. Results indicate that the total stresses are discontinuous as the crack tip …

The Effect Of Volatile Fission Products On Fuel Motion In Nuclear Fuel Elements, Paul Sasa

Nuclear Engineering ETDs

Stringent licensing procedures for commercial nuclear reactor operation require an in-depth analysis of the phenomena associated with postulated reactor core overheating accidents. One aspect of nuclear reactor safety assessment is a prediction of fuel behavior associated with such postulated overheating events, which includes an assessment of the role of fission product inventory contained within irradiated fuel elements on fuel relocation potential. In general the gaseous fission product, such as Xenon and Krypton, have been considered the most likely candidates for fuel relocation due to gas dissolution from the fuel matrix and bubble expansion during fuel overheating; thus, such gaseous fission …

Real-Time Estimation Of Aerodynamic Coefficients By Means Of An Extended Kalman Filter, James Robert Kelsey

Electrical and Computer Engineering ETDs

A technique for estimation of the aerodynamic parameters of a flight vehicle from onboard measurements is presented.

An extended Kalman filter is used to extract the parameters in the presence of measurement noise and initial uncertainty of the parameter values. Computer generated data were used for the measurement information in lieu of actual flight data.

Several state models of varying complexity are studied in an attempt to find a model which yields adequate estimates while minimizing the required computation time.
