Some articles on measurements, measurement:

Stability Constants Of Complexes - Experimental Methods
... by Bjerrum is still the main method in use today, though the precision of the measurements has greatly increased ... used in the titration, and finally the experimental measurements in the form of titre and pH (or emf) pairs ... If that is the case, the titration can be monitored by other types of measurement ...
Schiehallion Experiment - Measurements - Surveying
... That the mean density of the Earth should so greatly exceed that of its surface rocks naturally meant that there must be more dense material lying deeper ... Hutton correctly surmised that the core material was likely metallic, and might have a density of 10,000 kg·m−3 ...
Lipid Bilayer Characterization - Electrical
... Electrical measurements are the most straightforward way to characterize one of the more important functions of a bilayer, namely its ability to segregate and prevent the flow of ions in solution ... Fundamentally, all electrical measurements of bilayers involve the placement of an electrode on either side of the membrane ... In such DC measurements, it is necessary to use electrochemically active electrodes to provide the necessary positive charges on one side and negative charges ...
Location Estimation In Sensor Networks - Setting
... A set of sensors acquire measurements contaminated by an additive noise owing some known or unknown probability density function (PDF) ... The sensors transmit measurements to a central processor ... Ideally, sensors transmit their measurements exactly to the processing center, that is ...
Se HCAT - SeHCAT Test Procedure
... scan is quoted at 5.3mSv and annual background exposure in the UK 1-3mSv.) Measurements were originally performed with a whole body counter but are usually performed now with an uncollimated gamma camera ... From these measurements, the percent retention of SeHCAT at 7 days is calculated ... With more frequent measurements, it is possible to calculate SeHCAT retention whole body half-life this is not routinely measured in a clinical setting ...
