Ocean wave energy continues to develop through innovation and a growing number of collaborations around the world. With vast resource on our doorstep it remains focal point in ocean engineering with great potential. In order for become more competitive serious player renewable mix, such innovations should not only benefit sector but also other technological applications by providing attractive ...

Wave energy composes a direct and easy way of harnessing power from the Ocean. Among the different techniques used, OWC devices stand as one of the most promising ones. NEREIDA MOWC demonstration project is a breakwater wave plant located in the Basque location of Mutriku, using Wells turbines and Doubly Fed Induction Generators (DFIGs). Since one of the main objectives when dealing with renewa...

Performance of wave-energy devices of the oscillating water column (OWC) type is greatly enhanced when a resonant condition with the forcing waves is maintained. The natural frequency of such systems can in general be tuned to resonate with a given wave forcing frequency. In this paper we address the tuning of an OWC seawater pump to polychromatic waves. We report results of wave tank experimen...

Visible light communications (VLC) in indoor environments suffer from the limited bandwidth of LEDs as well as from the inter-symbol interference (ISI) imposed by multipath. In this work, transmission schemes to improve the performance of indoor optical wireless communication (OWC) systems are introduced. Expurgated pulse-position modulation (EPPM) is proposed for this application since it can ...

The multi-chamber Oscillating Water Column (OWC) device has recently become more attractive due to its potential high efficiency. In this paper, the hydrodynamic performance of a single-, dual- and triple-chamber OWC-breakwater are investigated experimentally. first instance, quantitative comparisons implemented understand OWC-breakwaters. Specific attention been dedicated capture width ratio (...

A floating oscillating water column (OWC) wave energy converter (WEC) supported by mooring lines can be modelled as an elastically OWC. The main objective of this paper is to investigate the effects frequency ratio on performance OWC (oscillating column) devices that oscillate either vertically or horizontally at two different mass ratios (m = 2 and 3) through two-dimensional computational flui...

Ocean wave is one of the renewable energy resources that these days various devices are used to extract its energy. Oscillating Water Column (OWC) installed on the shore is one of the wave energy absorption systems which has received attention due to its simple structure. Investigation of the pneumatic power is of great importance in such systems as the conversion of wave energy to pneumatic en...

This paper describes the DCU-Lingo24 submission to WMT 2014 for the HindiEnglish translation task. We exploit miscellaneous methods in our system, including: Context-Informed PB-SMT, OOV Word Conversion (OWC), MultiAlignment Combination (MAC), Operation Sequence Model (OSM), Stemming Align and Normal Phrase Extraction (SANPE), and Language Model Interpolation (LMI). We also describe various pre...

A numerical study was performed to investigate the applicability of linear decomposition method for hydrodynamic energy conversion an oscillating-water-column type wave converter (OWC-WEC). Hydrodynamic problems OWC chamber were decomposed into excitation and radiation with time-domain based on potential theory. finite element applied solve flow in entire fluid domain including structure. The v...
