Frontal optic flow information has been previously used in robot design to solve obstacle avoidance problems [47], [48], [52], ground avoidance problems [35], [36], [44], [45], and speed control problems [53], [54].
Traffic control in congested waterways has recently become a challenging task demanding higher accuracy in ship navigation and advanced methods for collision or grounding avoidance.
Therefore, careful selection of patients appropriate for biologic therapies may be cost-saving on the ground of avoidance of ineffective conventional treatments, reduction of hospitalization costs, increased productivity, and reduction of indirect costs.
The Federal Aviation Administration says it's considering regulations that would cover use of ground collision-avoidance warning systems, night-vision goggles, more training for pilots and flight dispatchers and further efforts to improve risk assessment for flights in poor weather.
Essex student union's mature and part-time students' officer George Johnson, makes the case against on three bullet-pointed grounds: "Their corporation tax avoidance, their ridiculous overpricing and the fact that they make bad coffee".
Furthermore, an active ground-based laser collision avoidance system using photon pressure is being developed which will support debris mitigation measures.
Talking to children about the importance of effort and hard work, however well-intentioned and however true, or grounding them for their avoidance of schoolwork, will not help.
This avoidance of the middle ground would avoid the "risk of total ruin" in putting 100 percent in "the so-called 'medium' risk securities".
Occurrence of sage-grouse reflected landscape-level selection for big sagebrush, taller shrubs, and favorable thermal conditions and avoidance of bare ground and anthropogenic features.
Assuming the encamped mode involved within-patch foraging, habitat used for forage resources was characterized by features that have become familiar to managers including areas with taller shrubs, proximity to mesic areas, and avoidance of bare ground (Figure 4a; Wallestad 1971; Dunn and Braun 1986; Drut et al. 1994; Connelly et al. 2000; Aldridge and Boyce 2007; Dzialak et al. 2011b).
Attacks by birds of prey are unforeseeable and unavoidable, for most prey species the avoidance of open ground is an apparently invariant result in foraging studies with antipredatory behaviour of rodents [11].
