摘要： A wind farm/park having a plurality of spatially distributed wind turbines, including at least one upstream wind turbine and at least one downstream wind turbine. Each wind turbine includes a rotor with at least two blades. At least one downstream wind turbine is affected under certain wind conditions by a wake region generated by the upstream wind turbine and containing helical vortex structures formed at the tip of the blades of the upstream wind turbine. A geometry or configuration of one or more of the rotor blades of the upstream wind turbine is different from a geometry or configuration of the other blade(s) of the upstream wind turbine thereby creating a fixed asymmetry in the blade configuration so as to accelerate destruction of vortices in the wake of the rotor of the upstream wind turbine by exciting a natural instability of the blade tip vortices.

摘要： A new method for attaching an electrically conductive polymer to a rigid, semi-rigid or flexible polymer substrate is described. A layer of the conductive polymer is polymerised by chemical oxidation, e.g. using ferritosylate, followed by washing with a solvent which simultaneously removes residual salt and dissolves the surface of the polymer substrate. This results in an integration of the conductive polymer into the polymer network of the substrate. Several combinations of conductive polymers and substrates may be used, the most preferred combination being poly(3,4-ethylenedioxythiophene) (PEDT) on poly(methacrylate) (PMMA) substrates. The mechanical and chemical properties of the conductive polymer/substrate surface closely resemble those of the substrate surface. The surface resistance of the conductive polymer layer remains low while the surface layer at the same time adapts some of the mechanical properties of the substrate yielding a high conductivity surface with very good wear resistance. The method can be used for the manufacture of microflow devices, circuits in active implants, sensors, e.g. disposable strips for measurement of blood sugar, medical devices and utensils, circuits in optical devices or circuits and components for electronic and photographic devices, e.g. OLED screens.
摘要翻译：描述了将导电聚合物附着到刚性，半刚性或柔性聚合物基底的新方法。导电聚合物的一层通过化学氧化聚合，例如使用铁酸盐，然后用溶剂洗涤，同时除去残留的盐并溶解聚合物基材的表面。这导致将导电聚合物整合到基底的聚合物网络中。可以使用导电聚合物和底物的几种组合，最优选的组合是聚（甲基丙烯酸酯）（PMMA）（PMMA）基材上的聚（3,4-亚乙基二氧噻吩）（PEDT）。导电聚合物/基材表面的机械和化学性质与基材表面的机械和化学性质非常相似。导电聚合物层的表面电阻保持较低，而表面层同时适应基片的一些机械性能，产生具有非常好的耐磨性的高电导率表面。该方法可用于制造微流量装置，主动植入物中的电路，传感器，例如，用于测量血糖的一次性条带，医疗装置和器具，光学装置或电路中的电路以及用于电子和照相装置的部件，例如， OLED屏幕。

摘要： The invention relates to birefringent optical fibres, used as e.g. polarisation maintaining optical fibres. More specifically, the invention relates to distributing different material compositions in the fibre to increase the birefringence in the core of the fibre. By applying topology optimization methods based on finite element analysis, fibre designs with three different material phases are produced which significantly increase the birefringence in the fibre core. One of the phases have a lower Young’s modulus than the others and may be void such as air holes. The invention proposes alterations to standard layouts such as the bow-tie or double bow-tie. The invention may also be applied on optical crystal fibres or photonic bandgap fibres.

摘要： Systems and methods are disclosed for polarization insensitive equalization of transients in an optical signal. The input optical signal has an input signal center frequency and an input signal bandwidth. The method includes passing the input optical signal through a non-linear optical waveguide to obtain a self-phase modulated optical signal. The method further includes filtering the self-phase modulated optical signal by a band pass filter. The band pass filter is centered at the input signal center frequency. In addition, the band pass filter has a band pass bandwidth equal or at least similar to the input signal bandwidth. The filtering results in a generation of equalized output optical signal.
