Nestmate recognition studies, where a discriminator first recognises and then behaviourally discriminates (accepts/rejects) another individual, have used a variety of methodologies and contexts. This is potentially problematic because recognition errors in discrimination behaviour are predicted to be context-dependent. Here we compare the recognition decisions (accept/reject) of discriminators ...

NoStop is an open source simulator dedicated to distributed and cooperative mobile robotics systems. It has been designed as a framework to design and test multi–agent collaborative algorithms in terms of performance and robustness. The particular application scenario of a team of autonomous guards that coordinate to protect an area from asymmetric threat is considered. NoStop system is an inte...

OBJECTIVE The perception of Nigerian athletes of the use of mouth guards to prevent the stresses of sports injuries was examined using psychological, sociological, and physical stress variables. METHODS The descriptive survey research design was used in this study. Participants (n = 333) were selected using the purposive random sampling technique and data were collected using the 4 point Like...

The aim of our study was to determine the differences in situational efficacy for basketball players, in relation to their team positions: between guards and forwards/centres, and between the players on the four major positions in the team. The final sample of subjects (74 basketball players) is selected from the initial sample of 107 subjects, selected from nine men's senior basketball teams t...

In the 1.5D terrain guarding problem, an x-monotone polygonal line is defined by k vertices and a G set of terrain points, i.e. guards, and a N set of terrain points which guards are to observe (guard). This involves a weighted version of the guarding problem where guards G have weights. The goal is to determine a minimum weight subset of G to cover all the points in N , including a version whe...
