PURPOSE/OBJECTIVES To review the state of the science on sleep/wake disturbances in people with cancer and their caregivers. DATA SOURCES Published articles, books and book chapters, conference proceedings, and MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and the Cochrane Library computerized databases. DATA SYNTHESIS Scientists have initiated studies on ...

The engineering wake models by Jensen [1] and Frandsen et al. [2] are assessed for different scenarios simulated using Large Eddy Simulation and the Actuator Line method implemented in the Navier-Stokes equations. The scenarios include the far wake behind a single wind turbine, a long row of turbines in an atmospheric boundary layer, idealised cases of an infinitely long row of wind turbines an...

Finnegans Wake presents a semiotic dilemma for the reader: How is it that the Wake means anything? And, Why doesn't it mean everything? To gesture, somewhat metonymically, toward the Wake itself: It is told in sounds in utter that, in signs so adds to, in universal, in polygluttural, in each auxiliary neutral idiom, sordomutics, florilingua, sheltafocal, flayflutter, a con's cubane, a pro's tut...

The lift-generated wake vortices trailing behind an aircraft present a danger to aircraft following the same or a nearby path. The degree of hazard to the following aircraft depends on the nature of the wake encountered in its flight path and on the ability of the aircraft to counter its effects. This report describes the current state of understanding of the factors that influence the motion a...

The production of ultrabright electron bunches using ionization injection triggered by two transversely colliding laser pulses inside a beam-driven plasma wake is examined via three-dimensional particle-in-cell simulations. The relatively low intensity lasers are polarized along the wake axis and overlap with the wake for a very short time. The result is that the residual momentum of the ionize...

Wind turbines are typically operated to maximize their own performance without considering the impact of wake effects on nearby turbines. There is the potential to increase total power and reduce structural loads by properly coordinating the individual turbines in a wind farm. The effective design and analysis of such coordinated controllers requires turbine wake models of sufficient accuracy b...

The modeling of the turbulent wake of a self-propelled body in a stratified fluid is discussed. The scaling parameter is taken to be the internal Froude number, using the speed and diameter of the body and Vaisala frequency of the fluid. Arguments are presented to suggest that the ratio of the time for the wake to collapse to the characteristic time of the turbulence is invariant with model sca...

The mismatch between traditional cipher designs and efficient operation on modern Very Long Instruction Word, Single Instruction Multiple Data, superscalar, and deeply pipelined processors is explored. Guidelines are developed for efficiently exploiting the instructionlevel parallelism of these processor architectures. Two stream ciphers, WAKE-ROFB and WiderWake, incorporating these ideas are p...

We study experimentally the vortex streets produced by a flapping foil in a hydrodynamic tunnel, using two-dimensional particle image velocimetry. An analysis in terms of a flapping frequency-amplitude phase space allows the identification of (i) the transition from the well-known Bénard-von Kármán (BvK) wake to the reverse BvK vortex street that characterizes propulsive wakes, and (ii) the sym...

Atmospheric turbulence has significant influences on both the trajectories and strengths of wake vortices. In this paper, a quasi-wavelet method is used to generate a random atmospheric turbulence field based on the von Kármán spectrum, in which atmospheric turbulence is represented by groups of random eddies. An inviscid wake vortex system, out-of-ground effect or in-ground effect, is immersed...
