Spatial Distribution Based on Semivariogram Model

open access: yesEconomic Journal of Emerging Markets, 2011
This article aims to discuss some aspects in conducting inferential analysis of census data.In this analysis, the assumptions of normality and IID (independently and identically distribution)in the observations are no longer realistic. Hence conventional

SPATIAL DISTRIBUTION OF OVERTOPPING [PDF]

open access: yesCoastal Engineering Proceedings, 2012
The scope of this research is to find an empirical formula to describe the distribution of wave overtopping in the region behind the crest. A physical model was set up in which irregular waves were generated. In order to find a formula which adequately describes the test observations, the influence of several parameters has been analysed.
