We derive the addition of velocities in special relativity from the Minkowski’s space-time diagram. We only need to draw some world lines on the diagram, measure the lengths and divide the two lengths ...

In many problems of combinatory analysis, operations of addition of sets are used (sum, direct sum, direct product etc.). In the present paper, as well as in the preceding one [1] , some properties of ...

Abstract: This paper considers modeling for tracking of extended objects using measurements of down-range and cross-range extent. Modeling smooth/non-smooth objects of complex geometric shapes using ...

Abstract: We present a new algorithm, based on the concept of contributing vertices, for the exact and efficient computation of the Minkowski difference of convex polyhedra. First, we extend the ...

An algorithm for approximating the Multidimensional Subset Sum problem. Using this algorithm we can also solve the Minkowski Decomposition of 2-dimensional polygons. The code is based on a paper under ...

A classification of [Formula: see text] contravariant Minkowski valuations on convex functions and a characterization of the projection body operator are established. The associated LYZ measure is ...
