Algorithms, nymphs, and shepherds
Computability and complexity are the two major lines along which the science of algorithms has evolved; but the same concepts guide many human activities. We try to catch some glimpses of the connections between these two worlds, to meet the expectations of the audience. We will encounter nymphs and universal Turing Machines, ancient traditions and randomized procedures, all tending to the same...
متن کاملGrowth Disorders in Young German Shepherds
Rapid Growth Problems The problems discussed here occur in the younger, rapidly growing German Shepherd. As German Shepherds are far more angulated than most breeds, they can appear to be having serious problems when in many cases they are going through fairly normal stages of development. Common problems are: 1. Excessive looseness of hocks, can be secondary to excessive depth of hindquarter a...
متن کاملAerial Shepherds: Coordination among UAVs and Swarms of Robots
We address the problem of deploying groups of tens or hundreds of unmanned ground vehicles (UGVs) in urban environments where a group of aerial vehicles (UAVs) can be used to coordinate the ground vehicles. We envision a hierarchy in which UAVs with aerial cameras can be used to monitor and command a swarm of UGVs, controlling the splitting and merging of the swarm into groups and the shape (di...
متن کاملChaotic Motions of F-Ring Shepherds
Recent HST images of the Saturnian satellites Prometheus and Pandora show that their longitudes deviate from predictions of ephemerides based on Voyager images. Currently Prometheus is lagging and Pandora leading these predictions by somewhat more than 20◦. We show that these discrepancies are fully accounted for by gravitational interactions between the two satellites. These peak every 24.8 d ...
متن کاملSymbiont acquisition alters behaviour of stinkbug nymphs.
In parasitic associations, the evolutionary interest of a symbiont contradicts that of a host, which sometimes causes the phenomena so-called 'parasite manipulation' wherein symbiont infection alters host behaviour to facilitate its vertical/horizontal transmission. In mutualistic associations, meanwhile, symbiont-induced alteration of host behaviour that enhances its transmission has been litt...
