Harmonic Source Location at the Point of Common Coupling Based on the Nonlinearity Index of Load

2009 Asia-Pacific Power and Energy Engineering Conference, 2009
Harmonic source quantitative location can not simply be achieved by the severity of load harmonic distortion at the point of common coupling (PCC) because the tested harmonic at PCC contains the background harmonic and the harmonic of given customer emission. Harmonics in distribution system are caused mainly by nonlinear loads.

CATALASE ACTIVITY AS AN INDEX OF MICROBIAL LOAD AND END‐POINT COOKING TEMPERATURE OF FISH

Journal of Rapid Methods & Automation in Microbiology, 1998
AbstractPsychrotrophs that are responsible for spoilage of many aerobically cold‐stored foods are strongly catalase positive. This study was conducted to ascertain the feasibility of using the Pasteur pipette catalase test developed by Fung (1985) to estimate the microbial population in raw fish during aerobic cold storage and to determine the end ...

Recommendation of Specimen Geometry in Determining Point Load Strength Index for Anisotropic Rocks

International Geomechanics Conference
ABSTRACT: The point load strength index (Is(50)) is the critical parameter in evaluating the mechanical response of rock. Due to its ease in specimen preparation, this index test becomes even more important for calculating the strength index of layered anisotropic rocks.

Relations Between Geologic Strength Index, Discontinuities and Point Load Strength Index of Some Rocks in Kemi Mine

59th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: In rock engineering practice, Geological Strength Index (GSI) is a well-accepted method for rock mass classification with cross cutting applications. For instance, during blast design and support prediction in tunneling, stope and foundation planning and development.

A validation study for the estimation of point load index at varying slenderness ratio

2019
This work reports the results of an experimental validation study of a recently developed analytical solution, by the group authors, for the measurement of rock tensile strength using diametrical point load strength index. Results, obtained from a series of more than 200 point load and Brazilian tests with a wide range of rocks, suggest that the ...

Granites of Dublin, Ireland: uniaxial compression strength, point load index and correlation analysis

Quarterly Journal of Engineering Geology and Hydrogeology
While the uniaxial compression strength ( UCS ) test is the gold standard for determining the UCS of rock for geotechnical and mining applications, empirical correlations between UCS and other test measurements such as point load index ( PLI )
