Examples of upwindupwind When required, carbon dioxide was released (2 1 min"1) from a position e l m upwind of the target. To ensure the upwind edge of the block was treated, the first spray run was 200 m upwind of the block. The upwind-biased schemes removed excessive energy from roughly three-quarters of the resolved wavenumber range owing to inherent numerical dissipation. For example, many can be expected to travel upwind to pats, perhaps like tsetse moving upwind to hosts. The use of the forward difference + in this new sink term is deliberate; we bias this difference to preserve the upwind nature of the scheme. The general experience seems to be however that upwind techniques compare unfavourably with centred approximations with respect to accuracy. Upwind approximations of the vorticity transport would solve the problem, but with a loss of accuracy. Most of the usual methods of approximation are discussed including the scheme of upwind differences. Section 3 was the upwind end from which the airflow entered the tunnel. After recording for 50 seconds the odour source was introduced at a point 3.5 m upwind of the robot. The left-hand wall-following behaviour carried it round the left-hand turn and the robot was once again following the chemical upwind. This control experiment investigates whether an algorithm incorporating precise odor packet location information is more efficient than a blind upwind surging behavior. A tendency for upwind movement could produce this effect if an additional behaviour discouraged flies from leaving a canopy. A 100 mm grid visible beneath the observation area divided into seven equal rows, with row 7 being at the upwind end. If wrong boundary values are supplied, the introduced errors will decrease exponentially upwind from this boundary. These examples are from corpora and from sources on the web.
