A complete set of filters Fn for the optimal-depth n-input sorting network problem is such that if there exists an n-input sorting network of depth d then there exists one of the form C ⊕ C′ for some C ∈ Fn. Previous work on the topic presents a method for finding complete set of filters Rn,1 and Rn,2 that consists only of networks of depths one and two respectively, whose outputs are minimal a...

Nomenclature (contlnued) The paper discusses the development and testing of a real-time Takeoff Performance M Pitching moment (ft_lb) Monitoring System. The algorithm is madeup of two MACH Mach number segments: a pretakeoff segment and a real_time p Roll Rate (rad/sec) segment, q Pitch Rate (rad/sec) One_time inputs of ambient conditions and r Yaw Rate (rad/sec) airplane configuration informati...

A large number of takeoff tests have been made on a Comet aircraft with the object of (a) acquiring comprehensive data on undirected takeoffs ; (b) testing a SCAT takeoff director. SCAT is explained in detail and the aircraft installation and test method described. Tests to determine ground effect on lift and on the SCAT Lift Transducer are also described. Undirected and directed takeoffs are c...

The doubly-labeled water technique and video were used to measure the effect of mass loading on energy expenditure and takeoff performance in zebra finches, Taeniopygia guttata, that were making routine (nonalarm) short flights. Finches that carried 27% additional mass did not expend more energy during flight than unloaded controls. Carrying additional mass, however, led to a reduced body mass ...

A microburst is a local, intense downdraft which induces an outburst of damaging winds near the ground which extends 4 km or less. Microbursts are of interest to researchers because of the strong, occasionally damaging surface winds they produce, and the hazardous wind patterns they create for aircraft in the landing or takeoff phases of flight. The dynamics and aircraft hazards posed by an iso...

In this paper, we propose a nonlinear transport model for an aviation network. The takeoff rate from an airport is characterized by the degree of ground congestion. Due to the effect of surface congestion, the performance of an airport deteriorates because of inefficient configurations of waiting aircraft on the ground. Using a simple transport model, we performed simulations on a United States...

This study used an optimization procedure to evaluate an 8-segment torque-driven subject-specific computer simulation model of the takeoff phase in running jumps for height. Kinetic and kinematic data were obtained on a running jump performed by an elite male high jumper. Torque generator activation timings were varied to minimize the difference between simulation and performance in terms of ki...

We calculate the flight performance of the gigantic volant bird Argentavis magnificens from the upper Miocene ( approximately 6 million years ago) of Argentina using a computer simulation model. Argentavis was probably too large (mass approximately 70 kg) to be capable of continuous flapping flight or standing takeoff under its own muscle power. Like extant condors and vultures, Argentavis woul...
