In recent years there has been much interest in the possible use of LIDAR systems for improving performance wind turbine controllers, by providing preview information about approaching field. Various potential benefits have suggested, and experimental measurements sometimes used to claim surprising gains performance. This paper reports on an independent study which detailed analytical methods two main purposes: firstly try evaluate likely LIDAR-assisted control objectively, secondly provide...
Through high order aeroelastic simulations in turbulent wind, it has been shown that a Scheduled Model Predictive Controller (SMPC) can successfully control wind turbine above rated conditions. The SMPC shows the ability to Multi-Input MultiOutput systems with multiple objectives, allow for system input constraints and also adjust aerodynamic nonlinearities of system. implementation is only as complex implementing Linear (LMPC) but provides benefits being able nonlinear higher performance....
Abstract As wind turbines are becoming larger, turbine control must now encompass load objectives as well power and speed to achieve a low cost of energy. Due the inherent non‐linearities in system, use non‐linear model‐based controllers has potential increase performance. A feedback linearization controller with an Extended Kalman Filter is successfully used FAST model controls advanced research active blade, tower drive‐train dynamics above rated conditions. The exhibits reductions shaft...
Interfacial and electrical properties of atomic-layer-deposited gate dielectric on epitaxial GaAs (epi-GaAs)/Ge bulk substrates have been investigated. Atomic layer deposition provides a unique opportunity to integrate high quality dielectrics epi-GaAs. The cross-sectional transmission electron microscopy /III-V stack shows similar interfacial thickness for p-GaAs epi-GaAs substrates. However, X-ray photoelectron spectroscopy Ga oxide-rich after postdeposition annealing at films grown...
n-type polycrystalline silicon (poly-Si) films with very large grains, exceeding 30 μm in width, and high Hall mobility of about 71.5 cm2/V s are successfully prepared by the solid-phase crystallization technique on glass through control PH3 (2% H2)/SiH4 gas flow ratio. The effect this ratio electronic structural quality poly-Si thin film is systematically investigated using measurements, Raman microscopy, electron backscatter diffraction (EBSD), respectively. grains found to be randomly...
High-quality n-type solid-phase crystallized (SPC) polycrystalline silicon thin films are successfully made on planar glass by controlling the stress and intragrain misorientation in films. If not controlled, is found to exceed 650 MPa, with a high of up 5°. The engineered values below 130 MPa through control a-Si:H deposition temperature PH3 (2% H2)/SiH4 gas flow ratio. misorientations SPC poly-Si affect their crystal quality. best quality also have least tensile low about 1°. effects ratio...
In this study, we evaluate the impact of interdigitated metallization patterns on 1-sun performance poly-Si thin-film solar cells glass. We implement a model cell with an pattern in simulation software Silvaco Atlas. Simulation and experimental results show consistently that dominant factor for is its current generation capability cell. For reason, study effect variation emitter finger pitch, rear contact size, carrier lifetime generation. pitch between 500 600 μm, efficiency varies by less...

Laser chemical processing (LCP) is an attractive doping technique for thin films due to its process simplicity, high achievable concentrations, and relatively shallow depths. During LCP processing, infinite supply of dopants available from the pressurized medium. In this paper, employed n-type poly-silicon on glass.

The cost of IPC has hindered adoption outside Europe despite significant loading advantages for large wind turbines. In this work we presented a method applying individual pitch control (including higher-harmonics) using tower-top strain gauge feedback instead blade-root feedback. Tower-top gauges offer hardware savings approximately 50% in addition to the possibility easier access maintenance and installation requiring less specialised skill-set than that required composite blade roots. A...
Retaining persons living with HIV (PLWH) in medical care is paramount to preventing new transmissions of the virus and allowing PLWH live normal healthy lifespans. Maintaining regular appointments an provider taking medication daily for a lifetime exceedingly difficult. 51% are non-adherent their medications eventually drop out care. Current methods re-linking individuals reactive (after patient has dropped-out) hence not very effective. We describe our system predict who most at risk...
