Adaptive meshless centres and RBF stencils for Poisson equation [PDF]
, 2011 We consider adaptive meshless discretisation of the Dirichlet problem for Poisson equation based on numerical differentiation stencils obtained with the help of radial basis functions. New meshless stencil selection and adaptive refinement algorithms are

A Two-Stage Method for Parameter Identification of a Nonlinear System in a Microbial Batch Process
Applied Sciences, 2019 This paper deals with the parameter identification of a microbial batch process of glycerol to 1,3-propanediol (1,3-PD). We first present a parameter identification model for the excess kinetics of a microbial batch process of glycerol to 1,3-PD.

Managing temporary workers in higher education: still at the margin? [PDF]
, 2006 Purpose – To evaluate whether “numerical flexibility” – specifically a form of temporary and precarious employment – hourly-paid part-time teaching in the UK higher education sector – adds strategic value and demonstrates good practice.

An Adaptive Method for Numerical Differentiation of Difficult-to-Compute Functions [PDF]
Journal of Mechanical Engineering, 2021 An adaptive approach to the numerical differentiation of difficult-to-compute functions is considered. Complex dependencies, which are the result of multiple superpositions of functions or the product of various algorithmic processes, are knowingly ...

Stronger computational modelling of signalling pathways using both continuous and discrete-state methods [PDF]
, 2006 Starting from a biochemical signalling pathway model expresses in a process algebra enriched with quantitative information, we automatically derive both continuous-space and discrete-space representations suitable for numerical evaluation.
