They also produce metal detectors for the consumer market. [11] The company has manufacturing, distribution and customer service operations in Adelaide (Australia), Cork (Ireland) and Naperville (US), and is an ISO 9001:2000 Quality Endorsed Company. Minelab was established in 1985 and was acquired by Codan in March 2008. [12]
In computing, serial presence detect (SPD) is a standardized way to automatically access information about a memory module. Earlier 72-pin SIMMs included five pins that provided five bits of parallel presence detect (PPD) data, but the 168-pin DIMM standard changed to a serial presence detect to encode more information.
A microchannel plate within a Finnigan MAT 900 sector mass spectrometer position-and-time-resolved-ion-counting (PATRIC) scanning array detector. An external voltage divider is used to apply 100 volts to the acceleration optics (for electron detection), each MCP, the gap between the MCPs, the backside of the last MCP, and the collector .
In a classification task, the precision for a class is the number of true positives (i.e. the number of items correctly labelled as belonging to the positive class) divided by the total number of elements labelled as belonging to the positive class (i.e. the sum of true positives and false positives, which are items incorrectly labelled as belonging to the class).
By computing a precision and recall at every position in the ranked sequence of documents, one can plot a precision-recall curve, plotting precision () as a function of recall . Average precision computes the average value of p ( r ) {\displaystyle p(r)} over the interval from r = 0 {\displaystyle r=0} to r = 1 {\displaystyle r=1} : [ 7 ]
A flame ionization detector (FID) is a scientific instrument that measures analytes in a gas stream. It is frequently used as a detector in gas chromatography . The measurement of ions per unit time makes this a mass sensitive instrument. [ 1 ]
The FDA has issued a statement following the Class I recall for an IOS app used in conjunction with insulin pumps after 224 injuries were reported.
A parity bit is a bit that is added to a group of source bits to ensure that the number of set bits (i.e., bits with value 1) in the outcome is even or odd. It is a very simple scheme that can be used to detect single or any other odd number (i.e., three, five, etc.) of errors in the output.
