Identifying predictors of evolutionary dispersion with phylogeographic generalised linear models by Wolff-Piggott, Timothy

“…The standard phylogeographic generalised linear model formulation, however, assumes that rates of spatial diffusion are a noiseless deterministic function of the set of covariates, admitting no other unobserved sources of variation. …”

Determining an optimum cropping pattern for Egypt by el Sayed, Loujaina M

“…A fuzzy goal programming (FGP) approach for optimal land allocation is utilized. In the model formulation, five goals were modeled; namely crop production, net profit, investment, fertilizers and water requirements. …”

Metabolomics approach to differentiation of citrus rootstock varieties susceptible or tolerant to Phytophthora nicotianae

“…In the second instance a predictive model for rapid selection of tolerant rootstocks was developed. The predictive model formulation is a de novo and interesting outcome in this study especially for a non-model plant species such as citrus. …”

Optimal crew routing for linear repetitive projects using graph theory and entropy maximization metric by Gouda, Ahmed

“…To meet the physical limitation of resources in linear projects, this study presents a flexible optimization model for resolving resource constraint dilemma in linear scheduling problems .The proposed model utilizes a MATLAB code as the searching algorithm to automate the model formulation. The novelty of this model is supplementing a new optimization engine and a decision supporting system that formulate the optimal crews routing between different activities in different units and guarantee the optimal crew distribution for cost efficiency. …”

Comparison of non-reactive solute transport models for the evaluation of fluid flow in leaching beds by Odidi, Michael Dumisane

“…The five semi-empirical models selected were the advection-dispersion (AD), piston exchange (PE), piston exchange-diffusion variant (PE-D) and piston dispersion and exchange (PDE) models. A novel model formulation called the piston dispersion and exchange-diffusion variant (PDE-D) model was also coded and tested, which incorporated both the longitudinal dispersion coefficient as well as a diffusional flux mass transfer mechanism. …”

Modeling and optimization of remanufacturing operations of spent products for sustainability by Heikal, Eman

“…For verifying the proposed model and its LINGO code, the data of a simplified version of the trailer case study was used to display the model and tracking the displayed model to assure that the generated code exactly matches the model formulation, and to discover and correct any logical error. …”

Development of a Kinetic Model for Low Temperature Fischer-Tropsch Synthesis by Davies, Imaad

“…By modelling FT synthesis as an equilibrium-controlled process, the kinetic model formulation could be simplified, consist of fewer rate expressions and contain the minimum number of model parameters without compromising on prediction quality. …”

Key performance indicators to predict the future performance of office nodes

“…Through the interviews, it became evident which key performance indicators (KPIs) are regarded by the property specialist as the most important KPIs to consider when investigating office nodes’ performance. In the model formulated, total return was used as the measure of the performance of the different nodes. …”
