A study of grain boundary structure in B doped Ni3Al
… the B-B equilibrium interatomic distance to the nearest neighbour distances in various (A₃B) Ll₂ compounds were calculated, in an attempt to predict the grain boundary fracture behaviour in these compounds. Selected area channeling patterns were obtained from a number of grains to solve for the …

The trend towards sociality in three species of southern African mole-rats (Bathyergidae) : causes and consequences
… content of the geophytes on which they feed and nearest-neighbour distances occurring between the belowground portions of the geophytes, may be crucial in determining whether a habitat is suitable for solitary or colonial mole-rats.

Modern k-Nearest Neighbour Methods in Entropy Estimation, Independence Testing and Classification
Nearest neighbour methods are a classical approach in nonparametric statistics. The k-nearest neighbour classifier can be traced back to the seminal work of Fix and Hodges (1951) and they also enjoy popularity in many other problems including density estimation and regression. In this thesis we …

Submillimetre Studies of Pre-stellar and Starless Cores in the Ophiuchus, Taurus and Cepheus Molecular Clouds
… surface density of sources, and small nearest-neighbour distances between sources. Taurus is a dispersed region, while Cepheus is intermediate. Ophiuchus shows the most variation of core properties with location. Cores in Taurus are extremely homogeneous; cores in Cepheus show a wide …

The influence of Microhodotermes viator nest density and dispersion on ecological processes
… of M. viator mounds were identified and their nearest neighbour distances and dispersion measures measured. High-resolution productivity data for these sites were obtained from the South African National Space Agency, and lowresolution productivity data from EarthExplorer for both autumn and …
