LIDAR (Light detection and ranging) systems are able to provide preview information of wind disturbances at various distances in front of wind turbines. This information can be used to improve the control of wind turbines. This paper compares a predictive feedforward control structure combined with common PI controllers to a baseline controller and to an H∞ approach showing the advantage of loo...

as a beam of light. It! reveals a system which?with certain honourable exceptions ?s degrading, unhygienic and inefficient. The authors are intelligent and observant women. Some of the orders they received were baffling and frustrating, and some were downright scandalous. Prisoners were obliged to carry 50 lb. bags of sugar, to man-handle enormously heavy barrels. and to move back-breaking load...

This review looks at the role of an alkaline diet in health. Pubmed was searched looking for articles on pH, potential renal acid loads, bone health, muscle, growth hormone, back pain, vitamin D and chemotherapy. Many books written in the lay literature on the alkaline diet were also reviewed and evaluated in light of the published medical literature. There may be some value in considering an a...

ROMM is a class of Randomized, Oblivious, Multi{phase, Minimal routing algorithms. ROMM routing ooers a potential for improved performance compared to fully randomized algorithms under both light and heavy loads. ROMM routing also ooers close to best case performance for many common permutations. These claims are supported by extensive simulations of binary cube networks for a number of routing...

We study the throughput and delay as a function of load, of data traffic in an IEEE 802.11 Wireless LAN using the public domain network simulator ns-2. We evaluate the Distributed Coordination Function (DCF) as well as the Point Coordination Function (PCF) modes of operation of IEEE 802.11 in detail. Although the PCF gives consistently higher throughput in the ranges of load studied, it has hig...

This work describes a system that allocates end-to-end bandwidth, in a switched meshed communications network. The solution makes use of market-based software agents that compete in a number of decentralised marketplaces to buy and sell bandwidth resources. Agents perform a distributed depth first search with decentralised markets in order to allocate routes for calls. The approach relies on a ...

Many dynamic scheduling techniques take advantage of out-of-order instruction execution to hide memory access latency. However, as the disparity between processor and memory speeds increases, delays in the load-store queue become more of a bottleneck. One way to mitigate these delays is to allow loads and stores to execute and retire from the load-store queue (LSQ) out-oforder. Unfortunately, w...
