Sleep, sleepiness, and circadian rhythmicity in aircrews operating on transatlantic routes.
This study was performed on B-747 aircrews operating on regular passenger flights between Frankfurt and the U.S. west coast (9 h time difference). In an initial phase, sleep behavior was surveyed by daily logs in 38 crewmembers. The results for the layover period indicate congruent sleep patterns with shifts in sleep onset distinctly less than 9 h. In comparison with preflight control data, sle...
متن کاملImpact of the North Atlantic Oscillation on Transatlantic Flight Routes and Clear-Air Turbulence
The variation of wind-optimal transatlantic flight routes and their turbulence potential is investigated to understand how upper-level winds and large-scale flow patterns can affect the efficiency and safety of long-haul flights. In this study, the wind-optimal routes (WORs) that minimize the total flight time by considering wind variations are modeled for flights between John F. Kennedy Intern...
متن کاملThe Transatlantic on 2200 Meters
here has been much excitement below our so-called top band at 1.8 MHz. At less than one-tenth this frequency, near 136 kHz, you will find many amateurs enjoying QSOs using a variety of modes. Although US and Canadian amateurs need special permission to transmit here, there is a 2200 meter amateur band in many European countries and in New Zealand. Aside from its low frequency, the most striking...
متن کاملTCP Behavior on Transatlantic Lambda's
Recent research in the area of high speed TCP has revealed that the protocol can misbehave in cases of high bandwidth long delay networks. Here we present work that clearly demonstrates this behavior of TCP flows in detail. This examination has led us to study the influence of the underlying network as well as the end user system using bursty a protocol such as TCP under such conditions. We des...
متن کاملCardiology: a transatlantic view (1).
As a cardiology trainee at the Massachusetts General Hospital I studied with Paul Dudley White. When Dr White reminisced about his medical career I heard tales of Sir Thomas Lewis and the events that led to the description of the Wolff-Parkinson-White syndrome. Dr White's experience in Britain formed the basis for the development of American cardiology. He brought back with him clinical and exp...
