Organised by waveform features rather than disease, this atlas helps to guide the reader to a diagnosis by essential features of a waveform. The first section takes the reader through the generation of a list of features on the EEG, which is then used to create a rubric for identifying possible diagnoses. The second section is organised alphabetically by general waveform title, referenced to in section one. This section also presents EEG tracings and discusses each waveform's distinguishing features and clinical significance.

This study examined the type I error and power properties of usual ANOVA, rank transform and aligned rank transform methods in the context of a balanced 2 x 4 fixed-effect layout. Different versions of F-test and Kruskal-Wallis test are used with four transformations (ranks, Blom normal scores, Van der Waerden normal scores, Savage scores) and three techniques of alignment (least-square, Lehmann, medians). In order to compare the robustness and the power of tests, simulations were employed for a variety of situations (absence or presence of nuisance parameters, small or large sample size, normality or non normality, equal or unequal variances). This study also examined these properties after a normal pre-test (moment test on standardized residuals) and a variance pre-test (Bartlett test or Brown-Forsythe test). The results showed that ANOVA is the more robust test among studies methods for all situations. Even if ANOVA has a moderate inflation in the type I error rate for some situations of unequal variances, non parametric alternatives of that study are not recommended for two-way fixed effects layouts.

Once applied only to problems of mining-reserves assessment or petroleum-reservoir characterization, geostatistics is now being used in an increasingly large number of disciplines in environmental sciences. On the one hand, it enables the analysis and handling, in a rigorous probabilistic framework of the issues of spatial and temporal interpolation of continuous or categorical environmental variables. On the other hand, the methodology is also used to design and optimize sampling campaigns. "Geostatistics for Environmental Applications" contains forty selected contributions covering the latest progress in a broad spectrum of fields including air quality, climatology, ecology, groundwater hydrology, surface hydrology, oceanography, soil contamination, epidemiology and health, natural hazards, and remote sensing.
