... This paper presents a Digital Filter method for real time prediction of waves incident upon a Wave Energy device. The method transforms waves measured at a point ahead of the device, to expected waves incident on the device. The relationship between these incident waves and power capture...

... ABSTRACT Impulse responses of digital filters for use in separating incident and reflected water waves in a time domain are improved by using a nonlinear least square formulation. The applicability and limitations of the method are discussed. Trial computations using a set of analytical...

... to be associated with large-amplitude extreme-like waves. Confirmation of the wavelet-based bicoherence results is provided by the decomposition of the experimentally observed wave elevation into its first- and second-order components. This is accomplished with the aid of a second-order Volterra digital filter...

... DPS thrust of a semi-submersible. KEY WORDS: Active control, TLP hull, Tendon, Long period response, Digital filter. INTRODUCTION A trend observed in the tendon of the deepwater TLP is the increased diameter of the tendon. By this design the payload of the TLP is secured, but the mass of tendon...

... ABSTRACT: The simulation of random wave records by the digital filtering method is discussed. After reviewing the existing recursive filters for the generation of surface elevation at one point, the paper introduces further recursive filters for the transmission of the motion to other points...

... ABSTRACT: This paper focuses on the real-time synthesis of the motion of a floating body in random waves. In particular, the radiation force is synthesized by two non-recursive digital filters. The transfer function for the radiation force is usually split into two components - one in phase...
