Physical and mechanical properties of endodontic absorbent paper points

Journal of Endodontics, 1981
Sixty-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

The validity of the virtual point detector concept for absorbing media

Applied Radiation and Isotopes, 2004
The 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.

Effects of the Mooring Line Configuration on the Dynamics of a Point Absorber

Volume 8: Ocean Renewable Energy, 2013
The 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, 1956
The 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, 1991
This 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), 2018
This 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, 1982
In 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, 2011
This 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

Causal Neural Control of a Latching Ocean Wave Point Absorber

2005
A causal neural control strategy is described for a simple "heaving" wave energy converter. It is shown that effective control can be produced over a range of off-resonant frequencies. A latching strategy is investigated, utilising a biologically inspired neural oscillator as the basis for the control.

A resonant point absorber of ocean-wave power

Nature, 1975
VARIOUS large scale systems have been proposed for absorbing and utilising the energy carried by ocean waves1–4. In principle, such a system consists of a damped oscillator which interacts with the wave. The net result is that energy is transferred from the wave to a load.
