Modulation Index Adjustment for Recovery of Pure Wavelength Modulation Spectroscopy Second Harmonic Signal Waveforms

A new technique of modulation index adjustment for pure wavelength modulation spectroscopy second harmonic signal waveforms recovery is presented. As the modulation index is a key parameter in determining the exact form of the signals generated by the technique of wavelength modulation spectroscopy, the method of modulation index adjustment is applied to recover the second harmonic signal with ...

Applying Diode Laser Wavelength Modulation Spectroscopy to Detect Oxygen Concentration

Oxygen is not only important which people rely on but also one type of important industrial gas. Considering that there are some disadvantages of traditional methods to measure the oxygen concentration, the tunable diode laser absorption spectroscopy is researched in this paper combined with the phase-lock amplify technique. This method combines the high power, good monochrome, wavelength tuned...

mortality forecasting based on lee-carter model

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...

Generalized Interface Polarity Scale Based on Second Harmonic Spectroscopy

Quantitative polarity scales have been of great value in advancing our understanding of chemical and physical processes in bulk solvents. However, an understanding of the polarity at liquid interfaces has been more elusive and no scale of interface polarity currently exists. Following our demonstration that second harmonic spectroscopy can be used to measure interface polarity, we have determin...
