The main objective of this study was to determine the accuracy of the temperature, relative humidity and C[O.sub.2] concentration measurements from the chosen wireless indoor environment sensors.
Blood glucose concentration measurements were taken 10 minutes before, 10 minutes and 20 minutes after administration of local anesthesia.
In each case, these proposed phenomena would explain the observations of IgG4-dependent positive biases with IN IgG1 and IgG2 concentration measurements, as compared with the corresponding LC-MS/MS measurements, and IgG4-dependent positive bias in the sum of the BSIN subclasses as compared with the total IgG method.
Quantitech's Craig Day says: "Oxygen gas concentration measurements are essential for the effective management of many industrial processes, providing an important indicator of combustion performance, fuel usage and process safety.
This analyser delivers a fast and reliable hydrogen concentration measurements in the following unit operations: catalytic reformer, hydrocracker, isomerisation unit, butamer off-gas, hydrotreater and fuel gas production.
On the serum obtained from the blood collected, aspartate aminotransferase (AST), alanine aminotransferase (ALT), albumin (ALB), total bilirubin (T.bil), totalprotein (TP), gamma glutamyltransferase (GGT), blood urea nitrogen (BUN) concentration measurements were performed in autoanalyser (Roche Cobas C111 Germany) by using the Roche Diagnostics Germany commercial kit.
This number has been confirmed by measurements taken at PTB on their quantitative flow cytometer, which has been qualified for high accuracy concentration measurements.

To overcome the problems of nonuniqueness and instability in the inverse source modeling problem, the most popular approach is regularization which emphasizes the selection of a "well-behaved" source configuration from the possibly infinite set of such configurations that are consistent with the limited number of noisy concentration measurements. In this approach, the idea is to find a source configuration that minimizes (optimizes) a penalty functional that involves two independent terms, namely, a regularization functional (source model norm) that imposes some constraint on the solution and a misfit functional (also some form of norm) that quantifies the discrepancy between the measured and predicted concentrations.
