ÐThe unsteady ̄ow of blood in a straight, long, rigid pipe, driven by an oscillatory pressure gradient is studied. Three di€erent non±newtonian models for blood are considered and compared. One of them turns out to o€er the best ®t of experimental data, when the rheological parameters are suitably ®xed. Numerical results are obtained by a spectral collocation method in space and the implicit tr...

Shy and non!shy individuals| attributions of shyness!resembling behaviors in scenarios involving either themselves or other\ hypothetical\ people were studied through the use of a questionnaire[ The participants were Swedish high!school students who rated the extent to which a number of such behaviors could be explained by four di}erent causes\ two internal "shyness and lack of interest# and tw...

In these supplementary materials we provide some details on the implementation of the methods developed in the paper. In addition we apply the di¤erent DID approaches using the data analyzed by Meyer, Viscusi, and Durbin (1995). These authors used DID methods to analyze the e¤ects of an increase in disability bene…ts in the state of Kentucky, where the increase applied to high-earning but not l...

In order to compare results published in [2] to those obtained in our experiments, we then selected ↵ so as to approximate as well as possible. The approximation is denoted ̂ in the following. If no reasonable approximation was found (that is the di↵erence between and ̂ was greater than 20% of ), no comparison was made since the objectives were considered to di↵er too much from each other.1 The...

The di erential geometry of autoregressive fractionally integrated moving average processes is developed. Properties of Toeplitz forms associated with the spectral density functions of these long memory processes are used to compute the geometric quantities. The role of these geometric quantities on the asymptotic bias of the maximum likelihood estimates of the model parameters and on the Bartl...

A nonparametric statistical model of small di€usion type is compared with its discretization by a stochastic Euler di€erence scheme. It is shown that the discrete and continuous models are asymptotically equivalent in the sense of Le Cam's de®ciency distance for statistical experiments, when the discretization step decreases with the noise intensity . Mathematics Subject Classi®cation (1991): P...

Some new estimates for the di¤erence between the integral mean of a function and its mean over a subinterval are established and new applications for special means and probability density functions are also given. 1. Introduction The classical Ostrowski type integral inequality [1] stipulates a bound for the di¤erence between a function evaluated at an interior point and the average of the func...

Recurrent Self Organizing Map RSOM is studied in three di erent time series prediction cases RSOM is used to cluster the series into local data sets for which corresponding local linear models are estimated RSOM includes recurrent di erence vector in each unit which allows storing con text from the past input vectors Multilayer perceptron MLP network and autoregressive AR model are used to comp...

We apply a computational measure of pronunciation di erence to a database of 36 word pronunciations from 490 sites throughout Stoykov's Bulgarian Dialect Atlases. The result is a comprehensive view of the aggregate pronunciation di erences among the 490 sites. This study aims to contribute therefore to Bulgarian dialectology, as well as to the development and testing of the computational techni...

| This paper compares two types of multiresolution data structure for data fusion, the data pyramid and the data cylinder. Data pyramids are well established, and in recent years non linear operators such as alternating sequential morphological lters have been used in their construction. The essential di erence between pyramids and cylinders is that pyramids undergo subsampling at each level. T...
