Latent class modelling of respiratory outcomes in a South African birth cohort by Mccready, Carlyle

“…Lung function measurements were adjusted for height (as a proxy for body size) using a multiplicative model approach. Prior to employing latent class mixed effects models (LCMM) to identify latent classes in longitudinal lung function data, generalised additive models for location, scale, and shape (GAMLSS) and interrupted time series (ITS) approaches were used to model the impact of LRTIs and other risk factors on longitudinal trajectories. …”

Sea-state interaction based dynamic model of the Liquid Robotics' Wave Glider: Modelling and control of a hybrid multi-body vessel by Rampersadh, Gevashkar

“…The multi-body system is described using DenavitHartenberg parametrisation and a Lagrangian approach is used to generate the equations of motion for the body. Physical dimensions are derived from platform measurements and from the product specification sheet, hydrodynamic factors are derived from a SolidWorks model of the system, and added mass components are determined from empirical data. …”

Macro-model of through silicon vias (tsvs) arrays by Ahmed, Karim

“…This work provides an algorithm to build a macro-model of an array of TSVs where only capacitive coupling is considered, as it is expected to be the dominating parameter.Using a simulation based technique, where characterization for bundles of TSVs were done and a scaling equation that can give the variationsoccur to capacitance value with scaling the physical dimensions of the TSV (pitch, radius, length and dielectric thickness (tox)) is proposed. …”

Numerical modelling of onshore wind turbine gravity foundations susceptible to cyclic soil degradation by Seymour, Steven

“…This was undertaken by: (1) analysing a case study of a wind farm in South Africa, and quantifying the effect of cyclic degradation on the foundation design for three separate ground profiles; (2) performing a parametric study to identify key parameters controlling cyclic degradation in the context of wind turbine foundations. Numerical modelling was undertaken to investigate these objectives, through the development of three-dimensional finite element models in the software package RS3 by Rocscience. …”
