Research on the Performance of Point Absorber
Advanced Materials Research, 2014Rational exploitation of wave energy makes great contribution to relief the current global energy crisis. Power generation has been taken into the agenda as the main form to utilize wave energy. The point absorber in this paper is simplified to three modules: floater, pontoon and chain.

The Concept of a Bipartite Point Absorber
1986A new wave power device is presented in the form of a bipartite point absorber. A simplified linear theory is used to demonstrate its satisfactory performance. An elaborate third-order theory however throws more light on the beneficial interactions between the composing parts, and on the strong nonlinear effects, which influence the power absorption in

The validity of the virtual point detector concept for absorbing media
Applied Radiation and Isotopes, 2004The concept of representing the detector volume by a virtual point detector in order to facilitate efficiency evaluations was proposed in the past for non-absorbing media. The validity of the model was expanded also to absorbing media present between the detector and a point source in front of it.

Physical and mechanical properties of endodontic absorbent paper points
Journal of Endodontics, 1981Sixty-six sizes of seven brands of endodontic absorbent paper points were evaluated to establish their physical and mechanical properties. A series of tests were to determine their dimensions (length, taper, tip diameter), absorbency, fiber-shedding propensity, and wet strength. A large variation in the properties exists between products and within any

Effects of the Mooring Line Configuration on the Dynamics of a Point Absorber
Volume 8: Ocean Renewable Energy, 2013The aim of this paper is to study the dynamics of a floating body with characteristics comparable to a point absorber wave energy converter with different mooring systems, in geometrical configuration or in the materials. To this purpose, the dynamics of a moored buoy is investigated.

The Localisation of Point Sources of Radioactivity in Absorbing Media
The British Journal of Radiology, 1956The accurate localisation of a point source of radioactivity in an absorbing medium is frequently desirable and the theory has been developed by Mayneord (1950). The applicability of his formula to the localisation of small (“point”) sources of thorium in water has been tested by measuring the γ radiation from opposite sides of the container.

Bacterial Sampling by Absorbent Paper Points. An in vitro Study
Journal of Periodontology, 1991This in vitro study was designed to test the hypothesis that sampling of bacterial suspensions by absorbent paper points would accurately reflect the proportion of the bacterial species whether they are homogeneously or non‐homogeneously distributed in the sample site.

Maximising absorbed energy using neuro-adaptive controller for heaving point absorbers
2018 5th International Conference on Renewable Energy: Generation and Applications (ICREGA), 2018This paper presents a computation-friendly control approach to improve extracted power from sea waves with heaving wave energy converter. A Lyponov function based neuro-adaptive inverse controller is proposed for velocity tracking of the heaving buoy under resonance condition for maximum power transfer.

Numerical method for computing the power absorbed by a phase-controlled point absorber
Applied Ocean Research, 1982In an irregular wave the phase of an oscillating point absorber can be continuously controlled by a computer-operated hold-and-release mechanism. A numerical method for computing the amount of power absorbed by such a phase-controlled device is presented and discussed.

Design of a Point Absorber Inside the WindFloat Structure
Volume 5: Ocean Space Utilization; Ocean Renewable Energy, 2011This paper summarizes the modeling and testing that was performed to integrate a point-absorber type Wave-Energy Converter (WEC) within the WindFloat hull. The WindFloat is a floating structure supporting a very large (>5MW) wind turbine. By adding a wave-energy device to the structure, one can improve the overall economic cost of the project, since
