Three-axis platform simulation: Bond graph and Lagrangian approach [PDF]

open access: yes, 1979
A bond graph model is derived for the geometric constraints of a three-axis flight table. Gimbal dynamics are easily added even in asymmetrical and unbalanced cases. A method is introduced to make the local dependent inertias computable.

Research of geometry effects on the railway track in the alignment, represented in the form of geometric models, on the indicators of the dynamic interaction of the track and rolling stock

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2017
The article describes the approach of smoothing previous interpolation interval. Authors studied the influence of track irregularities in alignments between fixed points, realigned the length of the spline function on the distribution of bend values by ...

Geometric Modelling of Octagonal Lamp Poles [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2014
Lamp poles are one of the most abundant highway and community components in modern cities. Their supporting parts are primarily tapered octagonal cones specifically designed for wind resistance.

Procedural function-based modelling of volumetric microstructures [PDF]

open access: yes, 2011
We propose a new approach to modelling heterogeneous objects containing internal volumetric structures with size of details orders of magnitude smaller than the overall size of the object.

The Oblate Schwarzschild Approximation for Light Curves of Rapidly Rotating Neutron Stars [PDF]

open access: yes, 2007
We present a simple method for including the oblateness of a rapidly rotating neutron star when fitting X-ray light curves. In previous work we showed that the oblateness induced by rotation at frequencies above 300 Hz produces a geometric effect which ...

A geometric framework for modelling similarity search

open access: yes, 1999
The aim of this paper is to propose a geometric framework for modelling similarity search in large and multidimensional data spaces of general nature, which seems to be flexible enough to address such issues as analysis of complexity, indexability, and ...
