Modelling the Impact of Climate Change on the Polar Bear Population in Western Hudson Bay
… The first model is a discrete matrix model with time-dependent parameters, which are influenced by temperature increases. Sensitivity analysis is done on the model. Numerical simulations predict there exist several scenarios that result in polar bear extinction. When the impact of climate warming …

A simulation-based decision support system for finite population maintenance logistics
… modeled at their component level, with the lifetime of each component described by a probability distribution. These components are assumed to fail independently of each other and to cause end item failure if any one component should fail. Several component-level preventive maintenance policies …

Flexible Strain Detection Using Surface Acoustic Waves: Fabrication and Tests
… due to its passive, small size, fast response time, cost-effectiveness, and wireless capabilities. Development of SAW sensors allows investigation of their potential not only for measuring less-time dependent parameters, such as pressure and temperature, but also dynamic parameters like …

Prediction of Time-Dependent Stresses and Deflections in Prestressed, Concrete Girders: From Start of Fabrication to End of Service Life
… legal ramifications. Many factors affect the time-dependent deflections of these girders including; creep and shrinkage of concrete, prestressing relaxation, temperature variations and numerous fabrication conditions. The current models used to predict the deflection history are largely …

Graphics Processing Unit-Accelerated Numerical Simulations and Theoretical Study of Qubit Dynamics in Realistic Systems
… has been facing problems owing to the space and time domain scaling associated with the solutions of the many-particle time dependent Schrodinger equation (TDSE). Nevertheless, recent advances in computer hardware performance has made previously intractable two-particle problems readily solvable. …

Development and Application of Low-Order Computational Models of the Left Ventricle
… and described using a small number of parameters, allowing rapid computational simulations of LV dynamics. The LV is represented as a thick-walled prolate spheroid containing helical muscle fibers with nonlinear passive and time-dependent active contractile properties. The displacement …

Probing the chemical biology involved in the haem detoxification pathway of the human malaria parasite, plasmodium falciparum
… processes was identified. The most important time- dependent parameters were (1) changes in DV lumen volume, (2) uptake of RBC cytosol into the DV, (3) protease enzyme concentration within the DV, (4) basal levels of haemoglobin, haem and haemozoin and (5) the cellular effects of perturbing …

Mechanical behaviour of Clay-Shales (Argille Scagliose) and implications on the design of tunnels
… particular attention to the development of large time-dependent deformations. These deformations may develop either during the construction stage, causing instabilities of the tunnel face and unsafe working conditions, or remain hidden during the “short-term”, thus leading to complex problems when …
