The ANSI/HPS N13.1–2011 standard requires gaseous tracer uniformity testing for sampling associated with stacks used in radioactive air emissions. Sulfur hexafluoride (SF6), a greenhouse gas with a high global warming potential, has long been the gas tracer used in such testing. To reduce the impact of gas tracer tests on the environment, nitrous oxide (N2O) was evaluated as a potential replacement...
Real-world visual classification tasks typically need to deal with data observed from different domains. Inspired by canonical correlation analysis (CCA), we propose an enhanced CCA with local density for associating and recognizing cross-domain data. In addition to maximizing the correlation of the projected cross-domain data, our CCA model further exploits the local density information observed...
Lenstra-Lenstra-Lovász (LLL) is an effective lattice reduction algorithm in multi-input-multi-output (MIMO) system. Its modified version Fix Lenstra-Lenstra-Lovász (F-LLL) algorithm uses fix method to substitute round method in original LLL algorithm in processing the parameter aiming to largely reduce the algorithm complexity. However, with the number of antennas and iteration times increasing, performance...
The paper introduces about the analytical detection methods of the trace accelerant (ethanol, acetone, etc.) in a fire residue. It gives a remark on the sample pre-processing and its analysis method. By using some new pre-treatment methods (including Headspace, Solid Phase Micro Extraction SPME, Supercritical Fluid Extraction SFE, Liquid Phase Micro Extraction LPME, and Chemical Derivatization CD),...
