named κ in the following. As a consequence the temperature profiles react weakly to changes of the heating power intensity and deposition profile: “profile resilience ” of “stiffness”. Based on these observations a simple analytical transport model has been developed and tested on ASDEX Upgrade data [5]. It is based on the following assumption for the heat diffusivity: χe χ0 λT αe ∇Te Te κ βHκ (1) where λ, α and β are coefficients to be adjusted, Hκ is the Heavyside function equals to zero for ∇Te Te κ and to unity for ∇Te Te κ. We will show below that good results are obtained with α 0 5 and β 1. In the remaining of this paper, the units are mks except keV instead of eV for the temperatures. The usual definition of the perturbative heat diffusivity, which defines the propagation of heat pulses, is [6]: χHPe χPBe ∂χe ∂∇Te

quantitative, as well as qualitative, comparison with the ocean. It is found that reasonable layer depths are predicted using measured heating rates, and a value of the turbulent kinetic energy input to the water deduced from the mean surface stress. The effects of heating at depth can be comparable with wind

We recalibrate den Haan, Haefke, and Ramey's matching model to capture our preferred specification of `turbulence', modelled in terms of the transition dynamics of human capital after voluntary and involuntary job losses. Under our calibration, an increase in turbulence increases

, that not all forms of disk turbulence do this. Purely hydrodynamic turbulence, when it is imposed, simply causes fluctuations without a significant increase in transport. The interplay between numerical simulation and analytic arguments has been particularly fruitful in accretion disk theory and is a major

The usefulness of high-order schemes in astrophysical MHD turbulence simulations is discussed. Simple advection tests of hat profiles are used to compare schemes of different order. Higher order schemes generally need less explicit diffusion. In the case of a standing Burgers shock it is shown

. Simulations of the three-dimensional wake for xed Reynolds number and increasing spanwise dimen-sion show that large systems evolve to a state of spatiotemporal chaos, and suggest that three-dimensionality in the wake leads to irregular states and fast transition to turbulence at Reynolds numbers just beyond

In this paper, we consider a set of HTTP flows using TCP over a common drop-tail link to download files. After each download, a flow waits for a random think time before requesting the download of another file, whose size is also random. When a flow is active its throughput is increasing

and Zimbabwe. Livestock Water Productivity (LWP) is becoming a major area of research which aims at increasing agricultural productivity through the use of less water for both livestock and crops as an adaptation and mitigation strategy to Climate Change. Via BMZ funded research, IWMI and ILRI are attempting

by the last major merger should have decayed away. Turbulent velocites are found to vary slowly with cluster radius, being ∼ 25 % of σvir in the core, increasing to ∼ 60 % at the virial radius. We argue that more frequent minor mergers maintain the high level of turbulence found in the core where dynamical

Due to increasing research being conducted at ICASE in the field of fluid mechanics, future ICASE reports in this area of research will be printed with a green cover. Applied and numerical mathematics reports will have the familiar blue cover, while computer science reports will have yellow covers
