(American Society of Civil Engineers, 2010-08)Ground movements during excavation have the potential for major impact on nearby buildings, utilities and streets. Increasingly ground movements are controlled at the source. They are assessed by linking the ground loss ...
-
(University College Dublin. Departmetn of Civil Engineering, 2004-12)In Deliverable 10.1, a optimal methodology for combining precipitation information from raingauges, radar and NWP models (in this case HIRLAM) was described. It was based on an artificial neural network combination model, ...
-
(Inderscience, 2000)This is the second part of a two-part paper which addresses the issue of accuracy in weigh-in-motion (WIM) systems. The first part develops the statistical background necessary for any system of accuracy classification ...
-
(Trans Tech Publications Inc., 2009-05)This paper presents a novel approach for structural damage detection. The cross-entropy method is used to estimate the structural parameters of a simply supported beam from its response to a static load consisting of a ...
-
(IEEE, 2010-02)Rising wind generation penetrations and the distinctive inertial characteristics of associated turbine technology will impact system frequency control. While wind production will displace conventional synchronous ...
-
(Thomas Telford, 2003)Traffic loading crossing a bridge is simulated to analyse the correlation between the worst static and dynamic load case. The worst static cases are obtained through a Monte-Carlo simulation using weigh-in-motion (WIM) ...
-
(Elsevier, 2002-09)Two pilot scale biofiltration systems were constructed and installed at the University College Dublin Research Farm, Lyons Estate. Experimental units consisting of two pens in a 12 pen pig house were sealed off from other ...
-
(2009-09)Secondary cementitious materials (SCMs) such as ground granulated blast-furnace slag (GGBS) are used in increasing quantities in concrete practice internationally. While these materials offer benefits such as reduced CO2 ...
-
(Elsevier, 2010-10)The hypothesis of this research was that attitudes about the management of biodegradable municipal waste (BMW) are spatially variable, even within a city of modest (1.2 million) population. For a select number of representative ...
-
(Institution of Civil Engineers/Thomas Telford Publishing, 2008-08)This paper describes the results of static compression and tension load tests performed on three-instrumented large diameter Continuous Flight Auger piles installed in Dublin boulder clay. The piles developed very high ...
-
(Elsevier, 2009-07-29)The electronic properties and photocatalytic activity of X (N, C) / transition metal (TM=Ta, Hf, Fe) – codoped anatase TiO2 have been investigated using density functional theory. It was found that only the (N, Ta)-codoping ...
-
(Institution of Civil Engineers, 2013)Different definitions of the bankfull condition in rivers are based on morphological characteristics, boundary conditions and geometrical properties. Consequently, the magnitude and associated return period of the bankfull ...
-
(IEEE, 2010-05)Certain developments in the electricity sector may result in suboptimal operation of base-load generating units in countries worldwide. Despite the fact they were not designed to operate in a flexible manner, increasing ...
-
(IEEE, 2012-05)In this paper, we present an analysis of an electrostatic vibration harvester operating in the constant-charge mode. The goal of the study is to bound regions of control parameters where the system displays steady-state ...
-
(IEEE, 2012-07)In this paper, we present numerical bifurcation analysis of an electrostatic vibration energy harvester operating in constant-charge mode and using the in-plane gap closing transducer. We show how the system can be represented ...
-
(Optical Society of America, 1994-06-01)A reflection grating with a binary surface profile is presented that has high diffraction efficiency. The measured intensity for the + 1st diffracted order was 77%. The binary grating is composed of a minilattice with ...
-
(IEEE, 2010-12-10)Bang-bang phase-locked loops (BBPLLs) are hard nonlinear systems due to the nonlinearity introduced by the binary phase detector (BPD). In the presence of jitter, the nonlinear loop is typically analyzed by linearizing the ...
-
(Elsevier, 2010-08)The costs associated with the provision and maintenance of drinking water and wastewater infrastructure represents a significant financial demand worldwide. Maintenance costs are disproportionately high, indicating a lack ...
-
(Elsevier, 2003-09)Odour control from pig production facilities is a significant concern due to increased public awareness and the development of more stringent legislation to control production. Although many technologies exist, biofiltration ...
-
(2008-12)Increasingly, industrial operations adjoin residential communities. As the demand for natural resources increases, this problem is only more likely to exacerbate in coming decades. Thus, it is imperative to fully understand ...
