Exempel på hopper

• Single-legged hopping robotics research similar results, when the spring-mass type vertical hopper was controlled with a controller, called periodic forcing controller.

• This strategy regulated the hopper at different hopping heights and was efficient even when hopping over obstacles.

• There is no doubt that the survivors of the 1932 hopper campaign were reverting to the solitary phase in the area.

• The first generation studied were partly composed of stragglers from hopper bands and flying swarms.

• They ate large numbers of hoppers and scattered the bands, so that no swarms of adults were produced.

• In the northern parts where predators were not so abundant, the bands were nevertheless small, and numbers of green hoppers could be found.

• The mass of pellets required to refill hoppers and the mass of spilt pellets were recorded to calculate food consumption per bird per week.

• This may explain the occurrence of apparently unparasitised hoppers of the pallid type.

• He predicted28 that the hopper was unstable if the thrust occurred at maximum compression.

• This hopper included a translational offset mass in order to cause the tipping action that helped in forward propulsion.

• They are unanimous in saying that hoppers were far more numerous in 1930 and 1931 than they had ever been before.

• All the hoppers were comatose and none was seen in the act of feeding.

• The observations indicate that hopper colouring is, at least in some degree, associated with the colouring of the environment.

• In many cases it was observed that pallid hoppers were sluggish and easier to catch than the normal hoppers.

• The figures for many of the species include hoppers.
