SIMS: a capable method for BCN quantification

Applied Surface Science, 2000
Abstract Obvious matrix effects often inhibit major component analysis carried out with secondary ion mass spectrometry (SIMS). Although MCs+ secondary ions (M represents the element to be analyzed) are used — already know as matrix independent for some compounds — feasibility of SIMS quantification has separately be validated for each new system ...

In situ U–Pb SIMS (IN-SIMS) micro-baddeleyite dating of mafic rocks: Method with examples

Precambrian Research, 2010
Abstract An in situ U–Pb SIMS (IN-SIMS) method to date micro-baddeleyite crystals as small as 3 μm is presented with results from three samples that span a variety of ages and geologic settings. The method complements ID-TIMS geochronology by extending the range of dateable crystals to sizes smaller than can be recovered by physical separation. X-ray

SIM: a Korean signature extraction method

Proceedings of TENCON '93. IEEE Region 10 International Conference on Computers, Communications and Automation, 2002
The signature file method has been recently thought as a useful text retrieval method when inverted file method is not available. However, traditional word-oriented signature file methods cannot retrieve all the relevant text items in the variable-spacing environment such as Korean text.
