In this work, we present a comprehensive analytical model and results for an absolute pH sensor. Our work aims to address critical scientific issues such as: (1) the impact of oxide degradation (sensing interface deterioration) on sensor’s performance (2) how achieve measurement ion activity. The methods described here are based equations which have derived implemented in MATLAB code execute nu...

In this research, the feasibility of using mathematical modelling in the ball milling process has been evaluated to verify the hardness changes of an aluminium nanostructure. Considering the model of normal force displacement (NFD), the radius of elastic-plastic and normal displacement of two balls were computed by applying analytical modelling and coding in MATLAB. Properties of balls and alum...

Trapezoidal sheeting of thin-walled steel is applied frequently for roofing and cladding. As such, it is loaded by a concentrated load (at the support) and a bending moment. A recently developed model to predict the sheeting's failure behaviour leaves the question open whether mode jumping (the phenomenon where a plate dynamically changes its buckling mode during an increasing load) should be t...

Strategic decision makers are frequently faced with unstructured problems that cannot be solved adequately by analytical means. In such situations, a better decision-making approach is one based on stakeholders’ participation. A particular form of such an approach is known as participatory modelling, whereby participatory methods are used for knowledge elicitation while simulation modelling tec...

Genetic analysis of wood chemical composition is often limited by the cost and throughput of direct analytical methods. The speed and low cost of Fourier transform near infrared (FT-NIR) overcomes many of these limitations, but it is an indirect method relying on calibration models that are typically developed and validated with small sample sets. In this study, we used >1500 young greenhouse g...
