SIMS method of material wear diagnosis

2009 IEEE International Conference on Industrial Technology, 2009
The presented method is based on use of SIMS analysis. SIMS analysis allowed experimental demonstration of 100 … 300 times increase in the dissolved hydrogen concentration at a depth of 1 … 20 mm in the pipe wall after 20 years of operation. The hydrogen dissolved in the pipe wall from a gas flow in a gas-main pipeline.

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.

Layered constellation generation method based on SIM-OFDM

Optics Communications, 2020
Abstract A layered QAM constellation generation method is proposed and it is applied to the SIM-OFDM system. In this method, the bit sequence is grouped layer by layer according to the specific bit and mapped to the corresponding constellation points. In this paper, the 24QAM-SIM-OFDM, 48QAM-SIM-OFDM, 80QAM-SIM-OFDM and 120QAM-SIM-OFDM constellations

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 ...
