nowadays acoustic emission (ae) testing based on the kaiser effect (ke) is increasingly used to estimate the in-situ stress in laboratories. in this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3d code called the particle flow code (pfc) based upon the distinct element method. t...

OBJECTIVE To compare the utilisation of hospital beds in the NHS in England, Kaiser Permanente in California, and the Medicare programme in the United States and California. DESIGN Analysis of routinely available data from 2000 and 2001 on inpatient admissions, lengths of stay, and bed days in populations aged over 65 for 11 leading causes of use of acute beds. SETTING Comparison of NHS dat...

Abstract The peculiar motion of the observer, if not accurately accounted for, is bound to induce a well-defined clustering signal in distribution galaxies. This related Kaiser rocket effect. Here we examine amplitude and form this effect, both analytically numerically, discuss possible implications for analysis interpretation forthcoming cosmological surveys. For an idealistic cosmic variance ...

Let`1 ; ` 2 ; : : : ; ` d be disjoint parallel lines in the plane. A d-interval is a subset of their union that intersects eachì in a closed interval. Kaiser Discr. Comput. Geom. 18(1997) 195{203] showed that any system of d-intervals containing no subsystem of k + 1 pairwise disjoint d-intervals can be pierced by at most (d 2 ? d)k points. We show that this bound is close to being optimal, by ...
