If the effects of fluid rotation are neglected, one-dimensional theory for a single actuator disc gives a maximum power coefficient of 16/27. This is the usual Betz limit for the power of horizontal-axis wind turbines. Tandem discs are a more appropriate representation for a vertical-axis, Darrieum, wind turbine and give more accurate predictions of turbine performance when used in conjunction ...

Binary rewriting is becoming increasingly popular for a variety of low-level code manipulation purposes. One of the difficulties encountered in this context is that machine-language programs typically have much less semantic information compared to source code, which makes it harder to reason about the program’s runtime behavior. This problem is especially acute in the widely used Intel x86 arc...

We wish to report a case of lymphangioleiomyomatosis in an 86-yr-old female who presented with acute breathlessness on a background of increasing dyspnoea over a 3-yr period. She had been told that she had chronic obstructive pulmonary disease 2 yrs prior to this presentation, despite having never smoked. At the time of admission she was taking regular nebulised salbutamol but no other respirat...

Aims. We present the results of multi epochs imaging observations of the companion to the planetary host Gliese 86. Associated to radial velocity measurements, this study aimed at characterizing dynamically the orbital properties and the mass of this companion (here after Gliese 86 B), but also at investigating the possible history of this particular system. Methods. We used the adaptive optics...

Digital memory forensics consists of analyzing various components of a memory image from a compromised host. A memory image consists of data and processes that were running on the system at the time the image was created. Previously running processes are one of the key items in memory images to identify, including potentially hidden processes. Each process has its own paging structures that def...

In oxygen-sensitive excitable cells, responses to hypoxia are initiated by membrane depolarization due to closing of the K channels that is thought to be mediated by a decrease in reactive oxygen species (ROS). Because the mechanisms of hypoxic inhibition of ion transport of alveolar epithelial cells (Planes C, Friedlander G, Loiseau A, Amiel C, and Clerici C. Am J Physiol Lung Cell Mol Physiol...

Krause, M., C. Meinel and S. Waack, Separating the eraser Turing machine classes, Theoretical Computer Science 86 (1991) 267-275. By means of exponential lower and polynomial upper bounds for read-once-only n-branching programs we separate the logarithmic space-bounded complexity classes L,, NL,, co-NL, and P, for eraser Turing machines.
