Spend your time even for only few minutes to read a book. Reading a book will never reduce and waste your time to be useless. Reading, for some people become a need that is to do every day such as spending time for eating. Now, what about you? Do you like to read a book? Now, we will show you a new book enPDFd time series analysis univariate and multivariate methods that can be a new way to exp...

Chemical multiequilibria systems can be monitored efficiently with the aid of spectroscopic techniques. Both hard- and soft-modeling are effective and powerful tools to extract chemical information from spectroscopic data. Recently, hybrid approaches that combine the flexibility of soft-modeling with the precise solutions provided by hard-modeling have been proposed. Here, we tested the perform...

*Correspo Danish In Denmark, E-mail: sf Contract/ Fisheries. Outliers may hamper proper classical multivariate analysis, and lead to incorrect conclusions. To remedy the problem of outliers, robust methods are developed in statistics and chemometrics. Robust methods reduce or remove the effect of outlying data points and allow the ‘good’ data to primarily determine the result. This article revi...

x-ray absorption fine structure (xafs) spectroscopy was used to identify directly the metal speciation and local bonding environment of fe in sediments originated from dobczyce reservoir (poland); special attention was paid to analysis of samples collected from points situated at different distances from the land. the combination of traditional approach to data analysis as well as usage of mult...

The continuous improvement of fuel cycle simulators in conjunction with the increase computing capacities have led to a new scale scenario studies. Taking into consideration multiple variable parameters and observing their effect on evaluation criteria, these studies regroup several thousands trajectories paving different possible values for operational parameters. If global methods like sensit...

BACKGROUND There remain high rates of unintended pregnancy around the world. Adding an effective contraceptive to those who currently only use male condoms may reduce these rates. The aim of this study is to identify the prevalence of and factors associated with the combination use of an effective contraception with male condoms in sexually active women who are already using male condoms. MET...
