Moiré pointer for measurement instruments
In measurement instruments where measured values are indicated with a mechanical pointer and a graduated scale, the observation precision is increased often by adding an auxiliary mechanical pointer (needle) with a sub graduated scale. The auxiliary pointer moves in synchronization with the main pointer but at a higher speed. A constant velocity ratio between the auxiliary pointer and the main ...
متن کاملInstruments for the Measurement of Color
Color is defined as “ the sensation experienced or caused by light reflected from or transmitted through objects”. In the strict sense, we cannot directly measure perceived color, however we can measure and subsequently calculate certain factors which are responsible for producing this sensation of color. The quantification of the color properties of textile materials is of great economic value...
متن کاملInstrumental Variables Regression with Measurement Errors and Multicollinearity in Instruments
In this paper we obtain a consistent estimator when there exist some measurement errors and multicollinearity in the instrumental variables in a two stage least square estimation of parameters. We investigate the asymptotic distribution of the proposed estimator and discuss its properties using some theoretical proofs and a simulation study. A real numerical application is also provided for mor...
متن کاملMeasurement Instruments as a Tool for Advancing
We critically reflect on the field of organizational learning and present one way to advance this important area of research. We propose theory explication and empirical research – in particular research aimed at model testing and refinement – as viable avenues for addressing the fragmentation of the field. We identify the lack of measurement instruments for organizational learning as a key imp...
متن کاملMeasurement Of Scatter Factors For Small Photon Fields Using Gaf chromic EBT2 Film
Introduction: Small field dosimetry is challenging for radiotherapy dosimetry. measurement of the output factor in the air and water (Sc, Scp) is one of the input parameters for commissioning of treatment planning systems and beam modeling. The aims of this study are to measured Sc,Scp for small fields with EBT2 and Ion chamber and design a appropriate mini-phantom for small fi...
