The subsurface elastic stress fields in plane and axisymmetric contacts with friction under oscillating tangential loading are calculated via a very robust, high-precision method, which operates appropriate superpositions of analytic solutions for the respective Hertzian contact problems. Based on fields, two critical fatigue crack initiation criteria—the Smith-Watson-Topper (SWT) parameter Fin...

T HE essential pathology of constrictive pericarditis is the partial replacement of the epicardium and superficial myocardial layers by inelastic fibrous tissue. This interferes with diastolic filling of the ventricles and is recorded during right ventricular catheterization as a high end-diastolic plateau. In addition, the encasing and infiltrating lesion interferes with contractility and ther...

Working Paper 23 April 2016 Michael G. Findley, Adam S. Harris, Helen V. Milner, Daniel Nielson Does foreign aid enable or constrain elite capture of public revenues? Building on prominent debates in the foreign aid literature, we examine whether recipient preferences are consistent with a view – called here donor control theory – that foreign donors wield substantial control over the flow of a...

This study compares two new seasonal adjustment methods designed to handle outliers and structural changes: X-IZARIMA and GAUSUM-STM. X12-ARIMA is a successor to the X-ll-ARIMA seasonal adjustment method, and is being developed at the U.S. Bureau of the Census (Findley et al. (1988)). GAUSUM-STM is a non-Gaussian method using time series structural models, and was developed for this study based...
