Experience curves for wind power

International Journal of Energy Technology and Policy, 2004
The objective of this study was to improve the understanding of the use of different experience curves in energy analysis. The study was based on the application of experience curves to wind power systems, but the approach is generic and can be used in other energy technologies.

Determining the Power Curve Learning Curve Parameters

2000
The two power model learning parameters, ‘t1’ — the performance time for the first repetition, and ‘b’ — the learning constant, were discussed in Chapters 1 and 2.

A universal power transfer curve

IEEE Microwave and Wireless Components Letters, 2005
Power transfer between circular apertures at far-field distances is calculated using a widely applicable aperture distribution with adjustable sidelobe ratio. Power transfer efficiency is obtained by integrating the pattern out to the angle subtended by the receiving aperture.

Radio frequency power generation under power curve constraints

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents an approach to radio frequency (RF) power control along a power curve specified as a function of load impedance, which varies with time. The control algorithm was developed to control the output of electrosurgical generators but can be used in any other application, where for time-varying loads, some specific power, voltage and ...

Low Power Elliptic Curve Cryptography

2007
The designer of an elliptic curve processor is faced with many design choices that include the algorithm and coordinate system to be used. The power consumption of elliptic curve processors is becoming increasingly important as such processors find new uses in power constrained environments.

[Power curves in rhinomanometry].

Biomedizinische Technik. Biomedical engineering, 1989
In diagnostic evaluation of the nose and allergology, the transnasal pressure delta p and the volume flow V is measured during breathing. It is shown that information is lost when measurements are represented form of a rhinomanogram. It is proposed using the measurements to derive the power during breathing and the mean volume flow of a breathing cycle.

ReDAPT - Initial Operation Power Curve

2014
One of the key developments of the marine energy industry in the UK is the demonstration of near commercial scale devices in real sea conditions and the collection of performance and environmental data to inform permitting and licensing processes.The ETI’s ReDAPT (Reliable Data Acquisition Platform for Tidal) project saw an innovative 1MW buoyant tidal
