Auswirkungen der Anlagenkonzepte, Skalierung und Betriebsführungstrategie auf Generatorsysteme für Wellen- und Meeresströmungsenergieanlagen

Different concepts to harvest energy from ocean waves and marine currents are currently investigated. The applied generator system has a key role in this energy conversion process. This paper presents a systematic approach to the design process for the generator system by evaluating the requirements resulting from the function principle of the device, in this case an oscillating water column wave energy converter. Additionally the design process for a real device is described to show further impacts like scaling and device specific requirements

The same neuron may play different functional roles in the neural circuits to which it belongs. For example, neurons in the Tritonia pedal ganglia may participate in variable phases of the swim motor rhythms [1]. While such neuronal functional variability is likely to play a major role the delivery of the functionality of neural systems, it is difficult to study it in most nervous systems. We work on the pyloric rhythm network of the crustacean stomatogastric ganglion (STG) [2]. Typically network models of the STG treat neurons of the same functional type as a single model neuron (e.g. PD neurons), assuming the same conductance parameters for these neurons and implying their synchronous firing [3, 4]. However, simultaneous recording of PD neurons shows differences between the timings of spikes of these neurons. This may indicate functional variability of these neurons. Here we modelled separately the two PD neurons of the STG in a multi-neuron model of the pyloric network. Our neuron models comply with known correlations between conductance parameters of ionic currents. Our results reproduce the experimental finding of increasing spike time distance between spikes originating from the two model PD neurons during their synchronised burst phase. The PD neuron with the larger calcium conductance generates its spikes before the other PD neuron. Larger potassium conductance values in the follower neuron imply longer delays between spikes, see Fig. 17.Neuromodulators change the conductance parameters of neurons and maintain the ratios of these parameters [5]. Our results show that such changes may shift the individual contribution of two PD neurons to the PD-phase of the pyloric rhythm altering their functionality within this rhythm. Our work paves the way towards an accessible experimental and computational framework for the analysis of the mechanisms and impact of functional variability of neurons within the neural circuits to which they belong

ADVANCE IN MODELLING AND STRUCTURAL DESIGN OF WAVE ENERGY DEVICES

Despite the fact that the wave energy is a large resource of energy, the wave energy sector has not still delivered a cost competitive solution. The structural design of wave energy device (SDWED) project aims at accelerating the development of the sector. The project gathers international research communities around the development of design tools and a common design basis for wave energy devices in order to make these devices more competitive. The prospect of an overall wave-to-wire model has the potential of lowering the cost of energy and increasing the reliability of wave energy devices
