Measurement of tibial torsion : the results from musculoskeletal testing and motion analysis compared with those obtained from ultrasound

Slaven, Emily J. January 2008 (has links)
The purpose of this study was to establish validity for both musuloskeletal testing and motion analysis compared to ultrasound measures of tibial torsion. Twelve subjects between 18-30 years of age participated in the study. Each subject underwent 3 measures of tibial torsion: ultrasound, a musculoskeletal measure and motion analysis. There were no significant differences in the measure of tibial torsion generated by the ultrasound compared to musculoskeletal test (p values, right = 0.593, left = 0.388) neither were there difference between ultrasound and the motion analysis measures (p values, right = 0.541, left = 0.583). All three methods of tibial torsion measurement demonstrated good to excellent reliability across trials. These results indicate musculoskeletal testing and motion analysis provide a valid measure of tibial torsion in an adult population and should be considered when providing surgical recommendations. / School of Physical Education, Sport, and Exercise Science

Improving the service quality of a civil consulting engineering firm through benchmarking

Bellingan, Werner January 2007 (has links)
The civil engineering industry in South Africa has seen a steady decline in the number of professionals during the last few decades, however it is expected that the government and private sectors are to spend over R200 billion on infrastructure in the next few years. This increases the demand on civil consulting engineering firms to achieve greater productivity, with reduced time and human resources, which has had a profound effect on the quality of service delivered to clients. These firms need to gain a competitive advantage by consistently providing Service Excellence, which is superior to their competitors. One way of achieving this is by benchmarking firms against their competitors. In this research paper the Service Quality and Service Recovery procedures of Company X in Port Elizabeth were benchmarked against its competitors using a customised form of the recognised SERVQUAL research instrument - the SERVPERF questionnaire. The results proved to be invaluable because the survey revealed insightful information which can be used to their strategic benefit. Civil consulting engineering firms need to be aware that Service Excellence is an imperative in the service industry, but do not necessarily have to be perfect. Firms simply need to outperform their competitors to be rated as market leaders. Strategies to improve the Service Quality and Service Recovery of the firm under review are suggested and this work concludes with suggestions for future research projects, which may be beneficial to the researcher, the civil engineering industry and the economy of South Africa.

THREE-BEAM SHEARING INTERFEROMETER FOR MEASURING THIN FILM THICKNESS, SURFACE ROUGHNESS, AND SURFACE FIGURE.

Almarzouk, Kais January 1982 (has links)
A three-beam lateral shearing interferometer has been developed. The three-beam shearing interferograms consist of two sets of fringes, one of which acts as a carrier whose intensity is modulated by the second set. The depth of modulation is directly proportional to the phase difference between the middle beam and the outer beams. Phase errors on the order of π/2 cause every other fringe to go from complete dark to complete bright. Therefore, phase errors much smaller than π/2 can be detected. The three-beam interferometer is implemented in three ways: (1) thin film thickness measurement, (2) surface roughness measurement, and (3) surface figure measurement. The three-beam interferometer implemented to measure thin film thickness and surface roughness is accurate to 25 Å. Surfaces with different microstructure are characterized. We have found that each of those surfaces may have one or more of the following: (1) random roughness, (2) slow waviness, and/or (3) periodic structure. The three-beam interferometer is also implemented for testing optical surfaces. The three-beam interferometer is more capable in detecting small zonal errors than the two-beam interferometer. Three-beam interferograms of different surfaces are produced and analyzed. The three-beam interferometer has many advantages: (1) it is a stable, common path interferometer, (2) white light can be instead of coherent light to get rid of the effects of speckle and dust particles, and (3) it is a very low cost interferometer.
