C-start: optimal start of larval fish
We investigate the C-start escape response of larval fish by combining flow simulations using remeshed vortex methods with an evolutionary optimization. We test the hypothesis of the optimality of C-start of larval fish by simulations of larval-shaped, twoand three-dimensional self-propelled swimmers. We optimize for the distance travelled by the swimmer during its initial bout, bounding the sh...
متن کاملBroiler Production Explation–Steps to Start
There is nothing quite so helpless in this world as a baby broiler chick which has been snatched from the warmth of its surrogated mother, carted umpteen kilometers in a box dumped unceremoniously in a broiler shed and then told to get on with the job of making the boss a wealthy man. Yet within the space of 14 days, that same chick, under optimum conditions, will have increased its day-old bod...
متن کاملHydrodynamics of C-Start Escape Responses of Fish as Studied with Simple Physical Models.
One of the most-studied unsteady locomotor behaviors exhibited by fishes is the c-start escape response. Although the kinematics of these responses have been studied extensively and two well-defined kinematic stages have been documented, only a few studies have focused on hydrodynamic patterns generated by fishes executing escape behaviors. Previous work has shown that escape responses by blueg...
متن کاملStart Start Master - State Slave - State
A solution is presented to the problem of quickly detecting the end of an asynchronous parallel computation, in which processors exchange task request messages asynchronously, and termination occurs when all processors are idle and no messages are in transit. The proposed termination detection scheme is based on a nite automaton consisting of only two states, and one possible transition between...
متن کاملPre-start timing information is used to set final linear speed in a C-start manoeuvre.
In their unique hunting behaviour, archerfish use a complex motor decision to secure their prey: based solely on how dislodged prey initially falls, they select an adapted C-start manoeuvre that turns the fish right towards the point on the water surface where their prey will later land. Furthermore, they take off at a speed that is set so as to arrive in time. We show here that the C-start man...
