(ACS, 2008-03-15)Diffusion of the electron acceptor is the rate controlling step in virtually all biofilm reactors employed for aerobic wastewater treatment. The membrane-aerated biofilm reactor (MABR) is a technology that can deliver ...
-
(IEEE, 2011-05-15)In this work, we consider a system that consists of a microresonator and a ΣΔ type feedback loop control which is typically a part of inertial sensors. We describe this architecture as a dynamical system (an iterative ...
-
(VTT Technical Research Centre of Finland, 2011-10-18)Students of sustainability, in particular architectural students, are faced with a vast body of published work that forms an important part of their reference library. The idea of the precedent study is, traditionally, ...
-
(2008-11)For over 30 years various micro and macro models have been used for analysing masonry, but no strong consensus within the structural engineering community exists as to usage. Selection remains driven by field scenarios, ...
-
(Wiley, 2008-04-15)The potential of the membrane aerated biofilm reactor (MABR) for high-rate bio-oxidation was investigated. A reaction-diffusion model was combined with a preliminary hollow-fiber MABR process model to investigate reaction ...
-
(Elsevier, 2011-07)Many highway bridges carry traffic in two same-direction lanes, and modeling the traffic loading on such bridges has been the subject of numerous studies. Different assumptions have been used to model multiple-presence ...
-
(American Institute of Physics, 2007-07-26)The development of a theoretical model of the processes present during the formation of a holographic grating in photopolymer materials is crucial in enabling further development of holographic applications. To achieve ...
-
(Eugenides Foundation, 2011-10-13)Kernel density estimators are a non-parametric method of estimating the probability density function of sample data. In this paper, the method is applied to find characteristic maximum daily truck weights on highway ...
-
(CRC Press, 2011-08-01)The accurate estimation of site-specific lifetime extreme traffic load effects is an important element in the cost-effective assessment of bridges. In recent years, the improved quality and increasing use of weigh-in-motion ...
-
(IWA Publishing, 2003-08)Much research in Europe at present has been directed at generating and assessing modelling tools for use in catchment management, driven by the requirements and schedule of the Water Framework Directive. A logical first ...
-
(Elsevier, 2011-06)The paper considers two techniques to model the Cone Penetration Test (CPT) end resistance, qc in a dense sand deposit using commercial finite element programmes. In the first approach, Plaxis was used to perform spherical ...
-
(Elsevier, 2010-09)This paper investigates the applicability of a cohesive zone model for simulating the performance of bituminous material subjected to quasistatic loading. The Dugdale traction law was implemented within a finite volume ...
-
(Professional Engineering Publishing / SAGE Publications Ltd, 2010)This paper presents the equations of motion for a general articulated road vehicle, with variable numbers of wheels for the tractor and trailer. The equations are applicable to vehicle-bridge dynamic interaction problems ...
-
(Elsevier, 2012-11-12)Hydrological or hydraulic flood routing methods can be used to predict the floodplain influences on a flood wave as it passes along a river reach. While hydraulic routing uses both the equation of continuity and the equation ...
-
(BCRI, 2010-09-02)Highway structures such as bridges are subject to continuous degradation primarily due to ageing, loading and environmental factors. A rational transport policy must monitor and provide adequate maintenance to this ...
-
(Institute for Process and Particle Engineering, Graz University of Technology, Austria, 2013-04)Increases in fuel and feed prices are placing a significant burden on the poultry industry in Ireland and worldwide. For producers to meet their financial targets, increased performance and output is a key issue, now more ...
-
(Optical Society of America, 2011-04-01)Photosensitive polymers are of practical importance, and mass transport within such materials plays a critical role in their behavior. Building on the work in Part I [J. Opt. Soc. Am. B doc. ID 136413 (posted 5 January ...
-
Monomer diffusion rates in photopolymer material. Part I. Low spatial frequency holographic gratings (Optical Society of America, 2011-03-01)For photopolymers, knowing the rate of diffusion of the active monomer is important when modeling the material evolution during recording in order to understand and optimize their performance. Unfortunately, a confusingly ...
-
(Optical Society of America, 2012-03)In [1,2] an error (by a factor of 1000) in the diffusion rate of monomer in a photopolymer material used by the authors of [3], is presented. In [3] no errors are identified in our analysis and our physical evidence is not ...
-
(Optical Society of America, 2003-06-01)It is shown that both surface tilting and translational motion can be independently estimated by use of the speckle photographic technique by capturing consecutive images in two different fractional Fourier domains. A ...
