Modelling of light scattering by cirrus ice crystals using geometric optics combined with diffraction of facets
(University of Hertfordshire, 2005)A new 3D model of light scattering applicable to dielectric faceted objects is presented. The model combines Geometric Optics with diffraction on individual facets yet maintains the low computational expense of standard ... -
Modelling of the Spectral Energy Distribution of Fornax A : Leptonic and Hadronic Production of High Energy Emission from the Radio Lobes
(2015-02-01)We present new low-frequency observations of the nearby radio galaxy Fornax A at 154 MHz with the Murchison Widefield Array, microwave flux-density measurements obtained from WMAP and Planck data, and gamma-ray flux densities ... -
Modelling Performance : Generic formal processes in live digital performance
(Institute of Electrical and Electronics Engineers (IEEE), 2016-05-19)Most existing accounts of live performance concentrate on the specific features of individual works or on linking works according to commonly observed traits which allow their plausible inclusion in groups identified by ... -
Modelling productivity and resource use efficiency for grassland ecosystems in the UK
(2017-09-30)Estimating spatially resolved grassland productivity is essential for benchmarking the total UK productive potential to assess food, feed and fuel trade-offs in the context of whole systems analyses. Our objectives were ... -
Modelling protein interaction in CCS
(University of Hertfordshire, 1999)This is an account of the progress made to date in attempting to model proteins and their interaction as CCS agents under parallel composition. Some earlier work was done using CSP but that model ran into problems over ... -
Modelling real time systems functional requirements using existing data flow methods
(University of Hertfordshire, 1993)This report summarises the data flow models from existing real time systems development methodologies, and describes some of the problems with using them to define real-time system functional requirements. The motivation ... -
Modelling regional imbalances in English plebeian migration to late eighteenth-century London
(2018-08-01)Using a substantial set of vagrancy removal records for Middlesex (1777–86) giving details of the place of origin of some 11,500 individuals, and analysing these records using a five-variable gravity model of migration, ... -
Modelling risk of readmission with phase-type distribution and transition models
(2009)A patient with frequent past readmissions may have an increased risk of future readmission. The principal objective of this paper was to determine the risk of readmission, given individual patient's history of readmissions. ... -
Modelling seedling growth rates of 18 temperate arable weed species as a function of the environment and plant traits
(2004-06)Background and Aims: The early growth rate of seedlings in the exponential phase is an important ecophysiological trait in crop/weed competition models based on assessments of relative weed green area. An understanding of ... -
Modelling stigmergic gene transfer
(MIT Press, 2008)We consider an information-theoretic model studying the conditions when a separation between the dynamics of a ’proto-cell’ and its proto-symbolic representation becomes beneficial in terms of preserving the proto-cell’s ... -
A Modelling Study of Road Traffic Contributions to Ambient PM2.5 Concentrations in Lagos
(2019-10-30)As the fastest growing city in Africa, Lagos experiences extremely high levels of air pollution. While there are many sources of air pollution in Lagos, road traffic has been widely reported as the most prominent. Due to ... -
Modelling superscalar pipelines with finite state machines
(University of Hertfordshire, 1993)We are currently examining the use of Finite State Machines to model processor pipelines. Our aim is to discover the extent to which the complexities of modern superscalar pipelines are amenable to theoretical modelling. ... -
Modelling techniques for object-oriented design
(University of Hertfordshire, 1991)It is increasingly recognised that an object-oriented approach offers the most promising way forward for the design and production of software systems. In this paper we adopt this point of view, and discuss a problem which ... -
Modelling TeV gamma-ray emission from the kiloparsec-scale jets of Centaurus A and M87
(2011-03-09)The widespread detection of synchrotron X-ray emission from the jets of low-power, nearby radio galaxies implies the presence of electrons at and above TeV energies. In this paper we explore the possibility that the TeV ... -

Modelling the daily progress of light leaf spot epidemics on winter oilseed rape (Brassica napus), in relation to Pyrenopeziza brassicae inoculum concentrations and weather factors
(2002-02-15)The progress of light leaf spot (Pyrenopeziza brassicae) epidemics on winter oilseed rape was monitored in 1998/99 and 1999/2000 at Rothamsted, and weather factors and P. brassicae ascospore concentrations were recorded ... -
Modelling the dispersion of flashing jets using CFD
(2008-06-15)Risk assessments related to industrial environments where gas is kept in liquid form under high pressure rely on the results from predictive tools. Computational Fluid Dynamics (CFD) is one such predictive tool and it is ... -
Modelling the dispersion of particle numbers in five European cities
(2016-02-04)We present an overview of the modelling of particle number concentrations (PNCs) in five major European cities, namely Helsinki, Oslo, London, Rotterdam, and Athens, in 2008. Novel emission inventories of particle numbers ...
