Electrode length measurement in electric arc furnaces
Accurate measurement of electrode length in electric arc furnaces will result in decreased maintenance time, and improved plant productivity. This thesis describes the development of a microwave-based Soderberg electrode length-measurement system. Various methods of electrode-length measurement …

Novel Neutron Detector for n-n Scattering Length Measurement
The neutron-neutron (n-n) scattering length is a fundamental parameter in nuclear physics; however, measurements are plagued with large uncertainties caused by neutron detector cross talk. Many experimentalists also rely upon computer code to calibrate their neutron detectors. Experiments give one …

The design and construction of a laboratory facility for the measurement of reactor moderator parameters
… and vertical traverses. By means of a diffusion length measurement, which gave an "L” of 54.5 ± 2 cm, and a Fermi Age measurement, which gave a "r” of 357 ± 5 cm², the parameters of the pile were shown to be in good agreement with published data on graphite.

Electroless Nickel Plating and Spark Plasma Sintering of nano ZrO2 for Mechanical Property Enhancement
… toughness was calculated by indentation-crack-length measurement and three-point bend test of notched samples; flexural strength was measured by 3-point bend tests. The measured hardness is comparable to the results found in the literatures. The coated and uncoated zirconia show significantly …

Modeling of Microstructures and Stiffness of Injection Molded Long Glass Fiber Reinforced Thermoplastics
… the plasticating stage leading to a broad fiber length distribution. Fiber orientation distribution (FOD) is another highly anisotropic feature of the final injection molded parts induced by the mold filling process. The mechanical and other properties can be highly dependent on the fiber length …

Year 7 students' understanding of the relationship between area and perimeter
… and perimeter. This is an important part of the measurement strand of mathematics. Two methods of collecting data were used: a multiple-choice pencil-and-paper test item; and clinical interviews with a class of Year 7 students. Two Perth metropolitan government primary schools allowed access for …
