Li, Q. (author), Finn, Adrian J. (author), Doyle, Stephen J. (author), Smith, Robin (author), Kiss, A.A. (author)The synthesis of heat-integrated distillation sequences for energy-efficient separation of zeotropic multicomponent mixtures is complex due to the many interconnected design degrees of freedom. This paper explores the basis on which reliable screening can be carried out. To solve this problem, a screening algorithm has been developed using...book chapter 2023

Smith, C. (author), Marinica, R. (author), Verhaegen, M. (author)We propose an efficient approximation to the nonlinear phase diversity method for wavefront reconstruction from intensity measurements. The new method, iterative linear phase diversity (ILPD), assumes that the residual phase aberration is small and makes use of a first order Taylor expansion of the point spread function (PSF) performed for an...conference paper 2013

(author), Klapwijk, T.M. (author)This paper describes the key design features and performance of HARP, an innovative heterodyne focal-plane array receiver designed and built to operate in the submillimetre on the James Clerk Maxwell Telescope (JCMT) in Hawaii. The 4x4 element array uses SIS detectors, and is the first sub-millimetre spectral imaging system on the JCMT. HARP...conference paper 2008

Lioutas, A. (author), Smith, G.M. (author), Verhagen, H.J. (author)The scope of this research is to find an empirical formula to describe the distribution of wave overtopping in the region behind the crest. A physical model was set up in which irregular waves were generated. In order to find a formula which adequately describes the test observations, the influence of several parameters has been analysed. The...conference paper 2012

(author)In this paper we present a solution for efficient porting of sequential C++ applications on the Cell B.E. processor. We present our step-by-step approach, focusing on its generality, we provide a set of code templates and optimization guidelines to support the porting, and we include a set of equations to estimate the performance gain of the new...conference paper 2007

(author)In the present work, the microstructure and mechanical properties of Gilsocarbon graphite have been characterized over a range of length-scales. Optical imaging, combined with 3D X-ray computed tomography and 3D high-resolution tomography based on focus ion beam milling has been adopted for microstructural characterization. A range of small...conference paper 2015

Hung, S. (author), Cnossen, J.P. (author), Fan, D. (author), Smith, C.S. (author)Optical sectioning technologies achieve high precision localization by reducing the background photon count. We use tilted light-sheet microscopy to achieve optical sectioning in localization microscopy, enabling thick sample observation and low background photon count images. A deformable mirror was incorporated to generate a tetrapod point...conference paper 2021

Cristiano, E. (author), ten Veldhuis, Marie-claire (author), Wright, Daniel B. (author), Smith, James A. (author), van de Giesen, N.C. (author)Rainfall spatial and temporal variability are key points in the prediction of hydrological response. At the same time, catchment scale and characteristics also play important roles, especially in urban areas, where the high level of imperviousness combined with intense and localised rainfall causes fast responses (Ochoa-Rodriguez et al., 2015)....conference paper 2018

van de Ven, Daan (author), Hofland, Bas (author), van Kester, Dennis (author), Smith, Greg (author), Antonini, A. (author)When constructing land reclamations, often sand is placed on top of the coarse rock of the bund surrounding the reclamation. The use of a geometrically open filter between the interface of sand and rock could be cost effective. It is expected that even a geometrically open filter with sand on top of gravel might be stable due to the arching...conference paper 2023

(author)In quasibrittle materials the addition of specific microstructural features such as porosity can lead to departure from linear elastic behaviour prior to maximum force, followed by graceful failure. A simple but extreme example is reticulated vitreous carbon foam, with its opencell structure of brittle ligaments connected in a threedimensional...conference paper 2016

Mirmomeni, M. (author), Heidarpour, A. (author), Schlangen, E. (author), Smith, S (author)Concrete is recognized for being a fire-resistant construction material. At elevated temperatures concrete can, however, undergo considerable damage such as strength degradation, cracking, and explosive spalling. In recent decades, reuse of fire-damaged concrete structures by means of developing techniques to repair the degraded material has...conference paper 2016

(author)We demonstrate a novel closed-loop input design technique on the detection of particles in an imaging system such as a fluorescence microscope. The probability of misdiagnosis is minimized while constraining the input energy such that for instance phototoxicity is reduced. The key novelty of the closed-loop design is that each next input is...conference paper 2022

Direct solar water splitting could play an important role in the production of these solar fuels. One of the main challenges of this process is the charge separation and collection at the interfaces.
