(Optical Society of America, 2011-07-10)Modeling the propagation of light through free space and simple paraxial systems continue to be enduring, and practically important topics in optics. Is there anything new or interesting that remains to be said? Given the ...
-
(Optical Society of America, 2005-10-16)The number of samples required for efficient numerical simulation of wave propagation can be determined by a combination of Wigner phase-space techniques, wave energy confinement arguments, and a theorem relating energy ...
-
(Elsevier, 1997-07)The paper describes the use of algebraic linear programming for the minimum weight design of steel portal frames subject to the constraints of the Kinematic Theorem of plastic collapse. Minimum weight design is a classic ...
-
(Les Presses de l'Université Laval, 2009-06-22)There is a trend towards reducing heating and cooling requirements of buildings by using high levels of insulation, minimizing thermal bridging, and ensuring excellent air tightness, together with the operation of ...
-
(Elsevier, 2007-06-01)In this paper, statistics-based experimental design with response surface methodology (RSM) was employed to investigate the effect of operation conditions on photoelectrocatalytic oxidation of fulvic acid (FA) using a ...
-
(IWA Publishing, 2004)A gravel-based tidal flow reed bed system was operated with three different strategies in order to investigate its optimal performance for the treatment of high strength agricultural wastewaters. According to the three ...
-
(IEEE, 2011-06)Bang-bang phase-locked loops (BBPLLs) are inherently nonlinear systems due to the binary phase detector (BPD). While they are typically used for clock and data recovery, the ongoing trend toward digital loop implementations ...
-
(Institution of Civil Engineers, 2006-09-01)Algorithms based on simple one-dimensional stage–discharge models for compound channels have been developed and tested for overbank flow data from the UK Flood Channel Facility and the University of Ulster channel with ...
-
(University College Dublin, 2010)
-
(ASM, 2009-01)Using a modified rotating-disk reactor to sparge oxygen to Staphylococcus epidermidis cultures, we found that oxygen negatively regulates biofilm development by influencing the activity of {sigma}B. Under anaerobic conditions, ...
-
(IWA Publishing, 2012-07-10)Despite significant developments, the simple, lumped, conceptual, rainfall-runoff model is still widely used for flood forecasting. What may not be appreciated is that, while such models can often be calibrated to give ...
-
(Optical Society of America, 2006-11-01)Digital speckle photography can be used in the analysis of surface motion in combination with an optical linear canonical transform (LCT). Previously [D. P. Kelly et al. Appl. Opt. 44, 2720 (2005)] it has been shown that ...
-
(Geological Society of London, 2008-02)Recent peat failures in Ireland in the autumn of 2003 at Pollatomish, County Mayo and Derrybrien, County Galway have focused attention on such events. However, peat failures are not a recent phenomenon with possible ...
-
(Elsevier, 2011-05)Dewatered alum sludge, a widely generated by-product of drinking water treatment plants using aluminium salts as coagulants was used as main substrate in a pilot on-site constructed wetland system treating agricultural ...
-
(Getty Publications, 2006-05)Use of microcrystalline waxes for the protection of ceramic art objects from seismic events is an inexpensive and relatively popular technique in museum exhibition practice (Fig. 1). Unfortunately, because of the high ...
-
(American Society of Civil Engineering (ASCE), 2008-03)Foundation reuse is a tricky business at the best of times. For structures predating the mid-20th century, the challenge is exacerbated by the presence of a variety of foundation types, techniques, and materials no longer ...
-
(Elsevier, 2012-02)Concrete is traditionally used as the main component of wastewater facilities. The sulfate and acidic environment presents significant challenges. Supplementary cementitious materials (SCM) such as GGBS are being used in ...
-
(2003-02)The depletion of natural resources, the requirement for sustainable development and environmental restrictions, such as those associated with the Kyoto Agreement, makes the re-use of waste materials increasingly important ...
-
(2000-06)Irish aggregates have a satisfactory history of service regarding alkali-aggregate reaction despite containing significant amounts of chert and use for a period in conjunction with cements of high alkali level. An investigation ...
-
(NRC Research Press, 2008-12)Soil nailing is being used in many projects in glacial tills in Ireland, particularly to provide temporary support to steep slopes. Little design guidance is available for such materials and it is known that application ...
