In order to ensure a high accuracy of SHTB system, specimen calibration is usually carried out.
The topics covered are a brief summary on the principles of EBSD, specimen preparation, calibration of an EBSD system, experiment design, speed of data acquisition, data clean-up, microstructure characterisation (including grain size) and grain boundary characterisation.
Even if the right test specimens are used, calibration of magnification is problematic.
Centralized training of technicians, standardized protocols, and extensive quality control (QC) measures were implemented for collection, on-site processing, and shipment of MESA specimens, and routine calibration of equipment was performed.
The values of interfacial fracture toughness were obtained using the measured fracture stresses, obtained by dividing the fracture load by the specimen thickness, and the calibration of the J-integral as a function of phase angle (Fig. 5).
Such innovative approach is compared to established methods: (i) single specimen methods, based on the determination of the energy release rate, for the calculation of fracture toughness; (ii) a multi-specimen methodology for the calibration of the geometry factor.
The differences in sand behavior from different specimen sizes would affect the calibration of soil constitutive models, particularly those based on the critical state theory (Jefferies 1993; Manzari and Dafalias 1997), and their application in advanced numerical analysis.
This specimen was employed as a calibration of stem Phalacrocoracidae, and hence, the Anhingidae/Phalacrocoracidae split.
Finally, specimen identification will allow for a basic calibration of the current visual shore-spawner survey index to an estimate of absolute abundance.
Autorotation of the specimen through a range of imaging angles and better calibration of the microscope stage have dramatically reduced exposure time.
