Service optimization and energy conservation requires a thorough understanding of the performance impact of different hardware configurations. In this paper we focus on the configuration of memory and investigate the impact of memory dynamic voltage and frequency scaling (DVFS) on the performance of services/applications. We propose a quantitative metric called frequency sensitivity (FS) and study...
In recent years, ultraviolet-visible spectroscopy has been widely used for measurements of water quality in seawater, because full spectrum contains large amounts of information. NO3 can be detected in 220–230 nm, and chemical oxygen demand (COD) and total organic carbon (TOC) can be detected in 280–290 nm. In visible spectrum, water color, turbidity and total suspended solids (TSS) can be measured...
The Black-Litterman model is inadequate in measuring risks of investment products. The author makes changes for the original model based on inflation, and make a new model named Black-Litterman-Inflation model. By mathematical test, the author proves that the Black-Litterman-Inflation model is more reasonable in asset allocation for fighting against inflation than the Black-Litterman model. Besides,...
Intensity-modulated surface plasmon resonance (SPR) array sensor based on polarization control was introduced and the impacts of incident angle, gold firm thickness, polarizer angle, wavelength and data processing on its sensitivity and measuring range were analyzed. It was concluded that in an easily controllable measurement range, an appropriate parameter selection can be set and produce high sensitivity...
