The Big Bush Machine by

In this paper we study an example-machine Bush(S, T ) where S and T are disjoint dense subsets of R. We find some topological properties that Bush(S, T ) always has, others that it never has, and still others that Bush(S, T ) might or might not have, depending upon the choice of the disjoint dense sets S and T . For example, we show that every Bush(S, T ) has a point-countable base, is heredita...

Intra-individual variation of skin temperature recovery rate after cold water immersion among Japanese bush-cutter operators.

Recovery rates of skin temperature after cold water immersion tests and other measurements were recorded from 1978 to 1989 to assess the effects of vibration due to the use of bush-cutters on the health of 42 road-maintenance workers having an average age of 51.7 years. Their work and health conditions were controlled and checked systematically, and the incidence of white finger in 1989 was 2%....

Automatic Grass-Cutter Developed by Genetic Programming

This paper describes how genetic programming can be applied to a simple problem. The problem is to discover program, which can control grass-cutter on a toroidal grid with randomly arranged obstacles, to cut largest area without redundant moves. This paper shows, how selection of suitable individuals for creation of next generation of individual solutions (=programs) affects results.

Cutter Path Generation For 2.5D Milling By Combining Multiple Different Cutter Path Patterns

Different cutter path patterns have been shown to be efficient for different types of pocket geometries. However, for certain types of complex pockets, no single type of pattern produces efficient cutter paths throughout the pocket. In this paper, different cutter path patterns are systematically analysed and several existing heuristics for selecting cutter path patterns are discussed. Based on...
