This paper sets out to discuss ongoing activities in the tide and chart datum components of hydrography and charting. It expands on the paper presented at FIG (Fédération Internationale des Géomètres) in Brighton 1998 by Mr Matt Higgins and is a revised and updated version of the paper Chart Datum for Hydrography by GPS delivered by the present authors to the Survey 99 Congress, Sunshine Coast,...

To cope with the intermittent power supply of new renewable energies and demand fluctuations, Francis turbines are required to operate more in an extended operating range, far away from design point. With this behavior, it is very complex interpret trend vibration parameters typically used Condition Monitoring define reasonable alarm trip levels valid for all range unit working steady condition...

In this paper we assess the quality of colorimetric calibration of HDR images captured using the multi-exposure technique. Three cameras were used to take HDR photographs of 4 scenes containing a color checker chart (XRite) and custom color patches. These were also measured using a spectrometer to provide ground truth data. One of the scenes was then used as a training for 2 camera calibration ...

The presence of dispersion/variability in any process is understood and its careful monitoring may furnish the performance of any process. The interquartile range (IQR) is one of the dispersion measures based on lower and upper quartiles. For efficient monitoring of process dispersion, we have proposed auxiliary information based Shewhart-type IQR control charts (namely IQRr and IQRp charts) ba...
