The Moment

Methods are presented to construct a three-dimensional model of a composite surface asperity based on profile measurements taken in different directions. The theory used to accomplish this is based on least squares estimation to find a locus equation for the moment properties measured experimentally in five directions. The asperity model is developed based on this locus of moment properties of height and slope, which are used to interpolate in different directions to generate the base and sides of an asperity. Two examples are used to show how these techniques can be used. One is a face milled cast iron surface and the other a surface ground specimen of low carbon steel.

The Moment

At the moment, level of development of GIS technologies is such that it is possible to implement a model of emergence and development of emergencies using a single geographic information system, while having ability to use many functions embedded in the system, and accessing spatial data through an API interface. This paper gives an example of creating a three-dimensional model of an accident using QGIS tools, illustrating the capabilities of this GIS for solving emergency control tasks.
