Determining the predictive accuracy of whole tree modulus of elasticity (MOE) of 14-year-old loblolly pine using density and dynamic MOEs estimated by three different acoustic tools

Charles Essien, Brian K. Via, Qingzheng Cheng, Thomas Gallagher, more

European Journal of Wood and Wood Products > 2018 > 76 > 5 > 1535-1546

Resonance based acoustic tools for evaluating wood properties have been reported to be more accurate in estimating the expected log MOE than time-of-flight (ToF) ones. However, there is no published study on the variations within different brands on these two major classes of acoustic tools. In this study, models were developed to predict the whole tree static MOE (WMOE_T) and rupture (WMOR_T) using...

Distance error for determining the acoustic velocity of standing tree using tree morphological, physical and anatomical properties

Charles Essien, Brian K. Via, Thomas Gallagher, Timothy McDonald, more

Journal of the Indian Academy of Wood Science > 2018 > 15 > 1 > 52-60

Time-of-flight (ToF) acoustic tools is one of the most practical nondestructive methods for predicting tree stiffness. In the literature, 120 cm between probes has been adopted as the standard for the assessment of tree acoustic velocity. However, there is no empirical study supporting this assertion, hence this study is aimed at determining the effect of distance on error for a common ToF acoustic...

Sensitivity of acoustic tools to variation in equilibrium moisture content of small clear samples of loblolly pine (Pinus taeda)

Charles Essien, Brian K. Via, Thomas Gallagher, Timothy Mcdonald, more

Journal of the Indian Academy of Wood Science > 2018 > 15 > 1 > 10-20

There are several types of acoustic tools commercially available for wood characterization, but they are generally classified into resonance and time-of-flight (ToF) tools. This classification is based upon the mode of velocity estimation for wood. In this study, we explored how the equilibrium moisture content of small clear wood samples (2.5 cm × 2.5 cm × 41 cm) affect the predictive capabilities...

2016 IEEE International Conference on Healthcare Informatics (ICHI) > 439 - 448

2016 IEEE International Conference on Healthcare Informatics (ICHI)

The de-personalised Electronic Healthcare Record (EHR) for secondary use has suffered re-identification. The Realistic Synthetic EHR (RS-EHR) is a promising solution safe from the threat of re-identification. This paper addresses the problem of generating the RS-EHR without using the real EHR by exploiting published Clinical Practice Guidelines (CPG) and Health Incidence Statistics (HIS). The CoMSER...

Using barometers to determine the height for indoor positioning

Binghao Li, Bruce Harvey, Thomas Gallagher

International Conference on Indoor Positioning and Indoor Navigation > 1 - 7

2013 International Conference on Indoor Positioning and Indoor Navigation (IPIN)

It is well known that atmospheric pressure decreases when altitude increases. Models have been created to relate altitude or height to pressure. A barometer can measure the air pressure and then the altitude can be calculated. Before the era of GNSS, barometers were widely used to determine heights outdoors. The invention of GNSS was a revolution in positioning and navigation. However, it does not...

Zheng Wei, Jon Andrew Deakin, Bärbel Sabine Blaum, Dušan Uhrín, more

Glycoconjugate Journal > 2011 > 28 > 8-9 > 525-535

The rare N-unsubstituted glucosamine (GlcNH ₃ ⁺ ) residues in heparan sulfate (HS) have important biological and pathophysiological roles. However, it is difficult to prepare naturally-occuring, GlcNH ₃ ⁺ -containing oligosaccharides from HS because of their low abundance, as well as the inherent problems in both excising and identifying them. Therefore, the ability to chemically generate a series...

2010 Ubiquitous Positioning Indoor Navigation and Location Based Service (UPINLBS)

Wi-Fi fingerprinting is a technique which can provide location in GPS-denied environments, relying exclusively on Wi-Fi signals. It first requires the construction of a database of “fingerprints”, i.e. signal strengths from different access points (APs) at different reference points in the desired coverage area. The location of the device is then obtained by measuring the signal strengths at its location,...
