DESIGNING PITCH CURVES OF NON-CIRCULAR GEARS [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2018 The paper examines the design and generation of gear drives with non-circular gears. Gearings with a changing transmission gear ratio are used for the purposes of practical experimentation, even though “standard” gearings with a constant transmission ...

Turn-by-Turn Imaging of the Transverse Beam Profile in PEP-II [PDF]
, 2006 During injection or instability, the transverse profile of an individual bunch in a storage ring can change significantly in a few turns. However, most synchrotron-light imaging techniques are not designed for this time scale.

Primitive lattice points inside an ellipse [PDF]
, 2003 Let Q(u,v) be a positive definite binary quadratic form with arbitrary real coefficients. For large real x, one may ask for the number B(x) of primitive lattice points (integer points (m,n) with gcd(m,n) = 1) in the ellipse disc Q(u,v) < x, in particular,

Biomimetics, 2019 Optimal packing of 2 and 3-D shapes in confined spaces has long been of practical and theoretical interest, particularly as it has been discovered that rotatable ellipses (or ellipsoids in the 3-D case) can, for example, have higher packing densities ...

An Improved Method for Estimating Renal Dimensions; Implications for Management of Kidney Disease
Applied Sciences, 2019 Changes in renal dimensions, including total kidney volume, not only inform ongoing renal disease but also disease progression. Determination of renal dimensions can inform drug efficacy, is important for matching recipients with potential donors, and to

El discutido influjo de la Historia Roderici en el Cantar de mio Cid
E-Spania, 2013 L’hypothèse d’un rapport entre le Cantar de mio Cid et l’Historia Roderici a soulevé, comme on sait, une querelle vive et encore irrésolue. Cette étude se propose de revisiter la question en soumettant à un nouvel examen deux passages de la biographie ...

The perimeter of a flattened ellipse can be estimated accurately even from Maclaurin’s series
Cubo, 2019 For the perimeter $P(a,b)$ of an ellipse with the semi-axes $a\ge b\ge 0$ a sequence $Q_n(a,b)$ is constructed such that the relative error of the approximation $ P(a,b)\approx Q_n(a,b)$ satisfies the following inequalities \begin{align*} 0\le -\frac{
