Studies in the variability of pock counts [PDF]
Epidemiology and Infection, 1957 1. The relationship has been examined between the variance and the mean of pock counts made by a number of different workers.2. In all cases the variance was considerably greater than that expected if the distributions were of the Poisson form. Recent work of Westwoodet al.(1957) suggests that variation approaching the Poisson expectation can be ...

Inverse kinematic analysis for triple-octahedron variable-geometry truss manipulators [PDF]
, 2001 In this paper, a new triple-octahedron variable-geometry truss manipulator is presented. Its inverse kinematic solutions in closed form are studied. An input-output displacement equation in one output variable is derived.

Dual Transformation of Auxiliary Variables by Using Outliers in Stratified Random Sampling
MathematicsTo estimate the finite population variance of the study variable, this paper proposes an improved class of efficient estimators using different transformations. When both the minimum and maximum values of the auxiliary variable are known and the ranks of

Time variability studies with ROSAT [PDF]
International Astronomical Union Colloquium, 1995 AbstractAn overview over the mission of the X-ray astronomy satellite ROSAT (Röntgensatellit) is given with an emphasis on the first soft X-ray all-sky survey carried out with an imaging telescope. Several examples of time variability studies made possible by the all-sky survey are shown for active late-type stars. Two exceptional long-duration stellar
