A methodological framework to determine optimum durations for the construction of soil water characteristic curves using centrifugation
(De Gruyter Open, 2016-12-30)
During laboratory assessment of the soil water characteristic curve (SWCC), determining equilibrium at various pressures, is challenging. This study establishes a methodological framework to identify appropriate experimental ...
The effects of planting density on the structural timber properties of 23-year-old Irish-grown Sitka spruce
(NUI Galway, 2016-08-29)
In Europe, with the move towards more sustainable construction, there is an increasing demand for structural timber. The
purpose of this research is to explore new forestry management strategies, which will produce an ...
Viscoelastic creep of FRP reinforced glulam
(NUI Galway, 2016-08-29)
The reinforcement of timber using fibre reinforced polymer (FRP) rods or plates is widely accepted as an effective
method of increasing the strength and stiffness of members, while at the same time reducing the variability ...
Understanding the complexities of building physics and human behaviour in achieving a nearly zero energy building
(NUI Galway, 2016-07-27)
About 40% of the world’s energy consumption and approximately a third of greenhouse gas
emissions are associated with buildings. As the percentage of new buildings relative to existing
buildings is increasing at a rate ...
Diversifying techniques and neutrality in genetic algorithms
(SciTePress Digital Library, 2016)
This paper examines the implicit maintenance of diversity within a population through the inclusion of a layered genotype-phenotype map (GP-map) in a Genetic Algorithm (GA), based on the principal of Neutral theory. The ...
Retrofit solutions for Irish building stock: The impact of human behaviour
(NUI Galway, 2016)
Retrofitting buildings is recognised as the most immediate, pressing, and cost effective
mechanism to reduce energy consumption and carbon emissions in the building and
construction sector. It is necessary to double or ...
Infrared thermography technique as an in-situ method of assessing heat loss through thermal bridging
(Elsevier, 2016-11-17)
A key aspect in assessing the thermal standard of building envelopes is the quantification of the heat loss though thermal bridging, which can be expressed in terms of the linear thermal transmittance Psi. Values of W may ...
Smartphones, biometrics, and a brave new world
(Institute of Electrical and Electronics Engineers (IEEE), 2016-09-09)
In this article, we take a somewhat contrarian viewpoint - that biometrics may, in fact, offer solutions to many of today's cyber-security problems that appear with increasing frequency in prime-time news. This outcome ...
Influence of connection systems on serviceability response of CLT timber flooring
(TU Verlag Wien, 2016-08-22)
In this paper finite element analysis of a five layer cross-laminated timber (CLT) rectangular floor is presented. The model was developed using 3D shell elements with linear elastic orthotropic material properties. Support ...
Viscoelastic creep in reinforced glulam
(TU Verlag Wien, 2016-08-22)
The mechanical and physical properties of softwood timber can vary considerably as a result of the age and rate of growth of the tree and other environmental factors which affect the wood cell density and strength [1]. ...
