the parameters of infiltration equations have a key role to evaluate and design irrigation systems and it is essential to estimate them with high accuracy for increasing irrigation efficiency. in the present study, two approaches consisting multilevel optimization method using advance, recession and runoff data and the iparm model using advance and runoff data were compared for estimating infil...
BACKGROUND Uncertainty exists about the performance of the Framingham risk score when applied in different populations. OBJECTIVE We assessed calibration of the Framingham risk score (ie, relationship between predicted and observed coronary event rates) in US and non-US populations free of cardiovascular disease. METHODS We reviewed studies that evaluated the performance of the Framingham r...
A new technique to find the optimization parameter in TSVD regularization method is based on a curve which is drawn against the residual norm [5]. Since the TSVD regularization is a method with discrete regularization parameter, then the above-mentioned curve is also discrete. In this paper we present a mathematical analysis of this curve, showing that the curve has L-shaped path very similar t...
there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...
Aim Assessing how different sampling strategies affect the accuracy and precision of species response curves estimated by parametric distribution models. Major Taxa Studied Virtual plant species. Location Abruzzo (Italy). Time Period Timeless (simulated data). Methods We simulated occurrence two virtual with ecology (generalist vs specialist) extent. sampled their following strategies: random, ...
