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.

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.

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.

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 ...
