(ASTM, 2009-06)Waterworks sludge continues to be an inescapable by-product of the potable water treatment process. Accordingly, final disposal of the sludge remains one of the most significant pressing problems for the potable water ...
-
(NRC Research Press, 2007-05)The Multichannel Analysis of Surface Waves (MASW) technique, used to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has recently generated considerable interest in the geophysics community. ...
-
(NRC Research Press, 2011-07)Full-flow penetrometers have been shown to overcome problems experienced with the cone penetrometer when measuring resistance in very soft peat and organic soil, and give a much more uniform measure of resistance than the ...
-
(American Society of Civil Engineering (ASCE), 2004)Sustainability in the construction industry can only be achieved through a radical rethinking of building construction and reuse. This paper outlines the problems and offers innovative solutions that embrace technological ...
-
(Optical Society of America, 1995-04-01)Interferometric methods are widely used in surface metrology. A question that arises is how much information about the surface can be extracted from a given interferogram. For examination of the resolution limit ...
-
(Taylor & Francis, 2012-09)Growing worldwide interest in the exploitation of geothermal energy resources has led to a scenario where the technology routinely forms part of building-scale renewable energy feasibility studies. A thorough understanding ...
-
(International Network for Engineering Education and Research, 2011-08)Third level educators are increasingly being called on to clarify the nature of the education they provide and the contribution of their graduates to society. There is therefore considerable interest in the generic attributes ...
-
(SPIE, 2010-04-13)At present there is a global concern of environmental issues and future energy supplies, for instance global warming and the rapid depletion of fossil fuels. This trepidation has initiated a more critical investigation ...
-
(Elsevier, 2012-11)Significant research effort has led to improvements in our ability to estimate the ultimate bearing resistance of footings in sand. These techniques often estimate the footing resistance at relatively large displacements, ...
-
(IEEE, 2008-10-16)Bang-bang phase-locked loops (BBPLLs) are a class of PLLs with a binary-quantized phase detector (BPD). They are widely used in clock and data recovery circuits and have recently been implemented as digital BBPLLs for ...
-
(Elsevier, 2009-04-07)Phosphorus (P) desorption from P-saturated alum sludge, which was used as main substrate in a novel constructed wetland for wastewater treatment, was studied. Groups of batch experiments were designed and conducted to ...
-
(Trans Tech Publications, 2010-10)Increasingly historic masonry buildings are subjected to higher levels of traffic and rail vibrations due to urbanization and population growth. Deterioration and destabilisation of these buildings may result, especially ...
-
(Royal Irish Academy, 2010-12)Although peat slope failures have occurred in Ireland for many thousands of years their causal factors and the triggering mechanisms involved are poorly understood. A particular barrier to quantitative assessment of the ...
-
(Taylor & Francis, 2006-01)This research assessed the use of gypsum (CaSO4.2H2O) as a skeleton builder for sludge dewatering since polymer conditioning of sludge affected only the rate of water release, not the extent of dewatering. The use of gypsum ...
-
(National University of Singapore, 2007-11)This paper presents a building environmental assessment methodology developed for application in new commercial buildings in Ireland. In an attempt to address issues of specific national interest the development of the ...
-
(Springer, 2011-03-02)The purpose of this paper is to present a review of peat landslide events in Ireland since 2003, when two significant events occurred. Since 2003, there have been at least thirteen such events. Several of these events ...
-
(Optical Society of America, 2007-09-10)We perform a numerical analysis on the double random phase encryption/decryption technique. The key-space of an encryption technique is the set of possible keys that can be used to encode data using that technique. In the ...
-
(World Scientific Publishing, 2009-01)In this paper, we study the behaviour of a MEMS oscillator by applying methods of nonlinear dynamics. We model the system as a kicked damped oscillator and obtain the iterative maps that describe the MEMS system. The ...
-
(Elsevier, 2006-06)The photocatalysis of natural organic matter, fulvic acid (FA), by P25 TiO2 in terms of UV254 and TOC concentrations was investigated in this study. The experiments were conducted in a lab-scale photocatalysis-ultrafiltration ...
-
(Optical Society of America, 2006-04-17)The Fourier plane encryption algorithm is subjected to a known-plaintext attack. The simulated annealing heuristic algorithm is used to estimate the key, using a known plaintext-ciphertext pair, which decrypts the ciphertext ...
