Testing and evaluation

A retaining wall constructed on expansive soil can be subjected to lateral swelling pressures due to soil swelling, which may cause a significant horizontal deformation and bending of the retaining wall. In Australia, it is generally assumed that the backfill behind a retaining wall is non-expansive material. Therefore lateral swelling pressures induced by expansive soils are ignored in routine design.

In this research the effect of ground proximity on the lift, drag and moment coefficients of inverted, two-dimensional aerofoils was investigated. The purpose of the study was to examine the effect ground proximity on aerofoils post stall, in an effort to evaluate the use of active aerodynamics to increase the performance of a race car. The aerofoils were tested at angles of attack ranging from 0° – 135°. The tests were performed at a Reynolds number of 2.16 x 105 based on chord length. Forces were calculated via the use of pressure taps along the centreline of the aerofoils.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

The central concern of this study is to develop an ICT-literacy task-based assessment instrument that may be used to evaluate trainee teachers’ level of ICT-literacy. The current literature acknowledges the need for a measurement instrument that evaluates ICT-literacy levels. This type of measurement instrument is used as an entry-level testing tool for university and job placements. However, existing ICT-literacy assessment instruments are either too expensive to be implemented or too rigid with their expected answers; moreover, they are not tailored to a teacher’s individual needs.

The study "Studies on film forming corrosion inhibitors on aluminium alloy, AA2024-T3" presents key aspects of the film forming behaviour of the selected inhibitors and the test methods used to evaluate the inhibitor induced films in a chloride solution. This study also aims to provide significant insights to the film tenacity, the influence of the molecular structure as well as the film stability in the absence of inhibitors to provide a deeper understanding of the film forming and film breakdown mechanisms.

Foot rot of tomato is an important disease which causes severe loss in tomato production. The present study was carried out to evaluate five bioagents and six fungicides against Sclerotium rolfsii. Among the five antagonists tested the maximum inhibition was observed in Trichoderma virens (67%) and contrarily, no inhibition was observed in Bacillus subtilis. Six fungicides viz., carbendazim, captan, tebuconozole, copper oxychloride, hexaconozole and Tebuconazole +Trifloxytrobin at different concentrations (50, 100, 150, 200, 250 and 500 ppm), were tested.

In this paper, a traditional adjoint method is used to propagate ND uncertainty on reactivity and reactivity coefficients and estimate correlations between different states of the core. We show that neglecting those correlations induces a loss of information in the final uncertainty.
