Surface reconstruction from interferometric ISAR data
… Aperture Radar (ISAR) images is to construct a three dimensional (3D) model of the object being imaged. Generally, such models are constructed manually by an analyst based on a series of radar images and whatever other information is available. However, using multistatic radar, it is possible to …

Pro-oxidative and Pro-inflammatory Mechanisms of Brain Injury in Experimental Animal and 3D Cell Culture Model Systems
… brain injuries and (2) Development of a three-dimensional (3D) model system in order to mimic in vivo-like microenvironments to further broaden our knowledge in pro-oxidative and pro-inflammatory mechanisms and their cellular responses within 3D constructs. In the first study, we …

Illinois integral abutment bridges: behavior under extreme thermal loading and design recommendations
… the overall behavior of IABs. By fully modeling a large assortment of IABs in three dimensions with varying lengths, intermediate spans, skews, pile types, and loading conditions, we obtained a more comprehensive picture of parametric influences on IAB behavior, particularly for skewed …

Numerical modelling of geothermal borehole heat exchanger systems
… attention. This work is concerned with the modelling of borehole heat exchangers (BHEs), the commonest form of ground heat exchangers found in GSHP systems. Their careful design is critical to both the short timescale and long timescale performance of geothermal heat pump systems. Unlike …

Development of a Bulk Superconducting Magnet for Benchtop Nuclear Magnetic Resonance
… magnetic fields suitable for NMR. First a two-dimensional (2D) axi-symmetric model of a single ring, based on the wellestablished H-formulation, was developed and iteratively refined to remove numerical errors from the solution. This model was then validated against analytical solutions for the …

Three dimensional water quality modeling in a shallow lake with complex morphometry; implications for coolwater fish habitat under changing climate
… and hydrodynamic gradients that require a three dimensional (3D) model to accurately capture their temporal and spatial dynamics. The objectives of this research were to evaluate and apply a 3D coupled hydrodynamic and ecological model to a morphologically complex lake and to investigate …

Measurements and modelling of eutrophication processes in Lake Rotoiti, New Zealand
… Zealand, and the application of a lake ecosystem model, this study examined the spatial and temporal variability of phytoplankton biomass and made a detailed consideration of the performance of three-dimensional lake ecosystem models. To gain insight in the spatial variability in phytoplankton …
