Obstacle detection with ultrasonic sensors and signal analysis metrics
(Elsevier, 2017)
One of the basic tasks for autonomous flight with aerial vehicles (drones) is the detection of obstacles within its flight environment. As the technology develops and becomes more robust, drones will become part of the ...
A new optical method of continuously analysing the surface properties of a single pendant drop while obtaining quality bulk spectral and refractive index measurements of the liquid-under-test
(IOP Publishing, 2009)
The classical stalagmometer has been replaced by the tensiometer to measure surface properties from drop volume. From the drop period T1, converted into volume, the surface properties of the liquid can be obtained. In the ...
Commencement measurements giving fundamental surface tension determinations in tensiometry
(IOP Publishing, 2011)
This study provides experimental testing of a ray-tracing model of the tensiotrace that explores the measurement potential of a well-defined optical position in the tensiotrace signal known as the 'commencement'. This point ...
Fundamental limits of measurement in telecommunications: Experimental and modeling studies in a test optical network on proposal for the reform of telecommunication quantitations
(IOP Publishing, 2011)
Proposals for a review of the limits of measurement for telecommunications are made. The measures are based on adapting work from the area of chemical metrology for the field of telecommunications. Currie has introduced ...
RAST model: Simulation of tensiotraces to facilitate drophad engineering
(IOP Publishing, 2011)
Tensiography is a technique that determines the physical and chemical properties of a liquid by illuminating a growing pendant drop from within using a source fibre. Light reflected internally at the surface of the drop ...
A game assessment metric for the online gamer
(Faculty of Electrical Engineering and Computer Science - Stefan cel Mare University of Suceava, Romania, 2007)
This paper describes a new game assessment metric for the online gamer. The metric is based on a mathematical model currently used for network planning assessment. Beside the traditional network-based parameters such as ...
Experimental observations with ultra-speed imaging revealing new complex detail of drop separation processes from a large diameter drophead
(IOP Publishing, 2011)
An ultraspeed (5000 frames a second) camera has been used to record the drop separating from the photometric instrument the tensiograph. New insights into drop separation processes which have been evaluated in terms of the ...
High order mismatch shaping for low oversampling rates.
(IEEE, 2019-03-11)
Delta Sigma data converters employing high order dynamic element matching (DEM) allow for accurate signal conversion in the presence of DAC mismatch. However, at low oversampling rates, current high order DEM decoders ...
Enabling models of Internet eXchange points to support spatial planning: the case for East Africa
(Institute of Technology Carlow, 2019)
In 2009 fibre-optic cables landed on the East coast of Africa, the last major area of the world to be connected to the Internet triggering a decade of Internet development. During the same period there has been a general ...
Improving the visual stimuli for brain-computer interfaces
(Institute of Technology Carlow, 2019)
Visual stimuli are traditionally used to operate Brain-Computer Interface (BCI) systems employing the Steady State Visual Evoked Potentials (SSVEP) technique. In this technique, when a BCI user’s visual system is exposed ...
