Beran Estimation of the Fisher-Bingham and Curved Kent Distributions
A directional measurement can be considered as a point incident to the unit hyper-sphere S^(p-1). Techniques for developing statistical tools to analyze directional data have a long and established history. Due to this interest in directional statistics, several probability distributions have been …

The quaternion Bingham Distribution, 3D object detection, and dynamic manipulation
… orientations. This is given by the quaternion Bingham distribution-a maximum entropy probability distribution on the 4-D unit quaternion hypersphere. In this thesis, we apply the quaternion Bingham to two applications: 3-D object instance detection from RGB-D images, and robot ping pong. The …

Constructing the aesthetic sense : traversing scales of habitation in the Bingham Canyon Mine
… and are rarely engaged by human occupation. The Bingham Canyon Copper Mine near Salt Lake City, Utah is one of the largest man-made excavations on earth, and has been in production for over 100 years. It is a place with a rich cultural, technological, and natural history, and a place of dynamic …

Rheological Study of Concentrated Silica Suspensions
… experimental data was applied to the Bingham plastic model and the power law model and the power law model was found to describe the experimental data more closely than the Bingham plastic model. The parameters for these two models were correlated to solids concentration, pH and …

Petrogenesis of Eocene-Oligocene magmatism of the Sulphur Springs Range, central Nevada: The role of magma mixing
… mineralized, Eocene mixed magma systems like the Bingham porphyry Cu deposit 300 km farther to the east. The Sulphur Springs igneous suite ranges compositionally through rhyolite, dacite, andesite and basaltic andesite but is less alkaline than the Bingham volcanic suite. However, the alkali …

Rate and time dependent behavior of structural adhesives
… technique in conjunction with a modified Bingham model. Using the modified Bingham model, constitutive equations describing loading-unloading behavior are also proposed. The stress-strain behavior of the adhesives is shown to be significantly rate dependent. Further it is shown that a rate …

Simulação de escoamentos incompressíveis não newtonianos em dutos com expansão brusca
… de fluidos newtonianos generalizados: power-law, Bingham e Herschel-Bulkley. Esses modelos prevêem comportamentos pseudoplásticos e dilatantes, plásticos e viscoplásticos, respectivamente. Os resultados numéricos mostram diferenças entre as soluções newtonianas e não newtonianas para Reynolds …

Numerical modeling of submarine landslides and surface water waves which they generate
… sediments are considered: a viscous fluid, a Bingham-plastic fluid, and a Coulomb frictional material. Formulations of the dynamics are presented for the slides on a gentle uniform slope reactively coupled with the surface waves which they generate. The governing equations are solved by a …

Rheological investigations of debris flow materials
… workers that these materials have a plastic or Bingham plastic rheology. Clay slurries containing coarse grains, and artificial grain-fluid mixtures, display many features of granulo-viscous behaviour such as stick-slip phenomena, structural changes, and fluctuations in torque values. Flow …

Gaming and the simulation of history constructing perspectives of Machu Picchu
… and the story of its discovery by explorer Hiram Bingham in 1911. Bingham's expedition remains today the constituting myth of the site, captured in multiple documents, primarily Bingham's travel journal, but also in photography and cartographic drawings, made by Bingham himself during his …

Learning and Exploiting Camera Geometry for Computer Vision
… is described, called the mirrored normal-Bingham distribution. This distribution generalizes both the normal distribution in Euclidean space, and the Bingham distribution on the unit hypersphere. It is shown to inherit many of the convenient properties of these special cases: it is the …

An Investigation of Electro-Rheological Fluids in Engineering
… for the shear mode of operation based on the Bingham model. The prediction model is based on the (solid to liquid) weight fraction, applied electric field and strain rate. An ER clutch with a single disk was designed, and tested to validate the model. In Chapter 3, an ER valve experiment is …

Combining Probabilistic Shape-from-Shading & Statistical Facial Shape Models
… of facial shapes. Thesis presents how Fisher-Bingham (FB8) distributions are sampled using Gibbs sampling to give normal distributions on the tangent plane. These normal distributions are in turn combined with normal distributions arising from statistical models of facial shapes. Chapter 2 …

Finite element simulation of electrorheological fluids
… Second, among many models of ER fluid, the Bingham plastic fluid was chosen to represent the ER fluidic behavior in case of the heterogeneous ER fluid. Also, shear stress-strain rate relation of ER fluid was simulated in case of shear modes and pressure modes in both fluids; heterogeneous …

Développement de fluides électrorhéologiques et applications en contrôle semi-actif des vibrations
… une nouvelle théorie appelée “Quasi-Bingham’’ a été développée et un autre modèle empirique a été proposé. Cette nouvelle théorie peut être utilisée pour modéliser tous les fluides ER rhéofluidifiants. La relation entre l’effet ER et la permittivité a également été étudiée en détail …
