• In a recent study, measurements of lengths, diameters, and numbers of vessels contained in a peripheral vascular bed from distributing artery to arterial capillaries were made in the living animal. From the data, total crosssectional areas of the various portions of the arterial tree were calculated and compared with values from similar measurements of vessels in fixed tissue. In the living a...

The problem of experimental design for the purpose of estimating the fixed effects and the variance components corresponding to random nested factors is a widely applicable problem in industry. Random nested factors arise from quantity designations such as lot or batch and from sampling and measurement procedures. We introduce a new class of designs, called assembled designs, where all the nest...

A methodology was developed for estimating the parameters involved in a first-order autoregressive process; these parameters comprise a variance component associated with the random effect, a correlation coefficient, p, and a residual variance. These parameters were estimated using REML with an expectationmaximization algorithm. For two singletrait analyses (milk and fat production being the de...

The use of multitaper estimates for spectral proper orthogonal decomposition (SPOD) is explored. Multitaper and multitaper-Welch estimators that discrete prolate spheroidal sequences (DPSS) as data windows are compared to the standard SPOD algorithm exclusively relies on weighted overlapped segment averaging, or Welch's method, estimate cross-spectral density matrix. Two sets turbulent flow dat...

The impurity of measures is considered as cause of erroneous interpretations of observed relationships. This paper concentrates on impurity with respect to the relationship between working memory and fluid intelligence. The means for the identification of impurity was the fixed-links model, which enabled the decomposition of variance into experimental and non-experimental parts. A substantial n...

today, with the advanced statistical techniques and neural networks, predictive models of distribution have been rapidly developed in ecology. purpose of this research is to predict and map the distribution of tetranychus urticae koch (acari: tetranychidae) using mlp neural networks combined with genetic algorithm in surface of farm. population data of pest was obtained in 2016 by sampling in 1...
