We propose one parametric and one non-parametric method for detection of monotone trends in nutrient concentrations in brackish waters. Both methods take into account that temporal variation in the quality of such waters can be strongly influenced by mixing of salt and fresh water, thus salinity is used as a classification variable in the trend analysis. With the non-parametric approach, Mann-K...

variability only to a long term increasingly upward trend. To isolate and properly investigates the seasonal component and possible relationships with the sources of variation in skin cancer incidence it is necessary to separate uncorrelated obscuring time scales such as random noise and the long term trend [7]. Separation is achieved using a combination of low pass Kolmogorov-Zurbenko Filters ...

investigation of inter-storm variability of runoff and soil loss characteristics helps experts and decision makes better understanding of hydrological response. however, this important has been less considered in the world, especially developing countries. the present study was therefore planned to evaluate the effect of different rainfall intensities and slopes on inter-storm variability of co...

Product Marketing Manager, Synopsys Introduction An accepted trend in the semiconductor industry, where process geometry is continuously shrinking, is the growing impact of variation in static timing analysis (STA). Similar to Signal Integrity (SI), which was introduced as a first order effect in 130-nm and then became more sophisticated over geometry nodes, on-chip-variation (OCV) started at 1...
