A multivariate Powell-Sabin interpolant

We consider the problem of constructing a C1 piecewise quadratic interpolant, Q, to positional and gradient data defined at the vertices of a tessellation of n-simplices in IR. The key to the interpolation scheme is to appropriately subdivide each simplex to ensure that certain necessary geometric constraints are satisfied by the subdivision points. We establish these constraints using the Bern...

In the pre-Internet era there was a significant time lag between the creation of a work by an author and the time a consumer read that work. The Internet has allowed authors to create and publish their work and disseminate across the world quickly. There has been an explosion of online content and publishing over the last decade. Most people believe that this trend is going to continue on a ste...

Diplopodia, or duplicated foot, is a rare congenital anomaly. It differs from polydactyly in that supernumerary metatarsal and tarsal bones are present as well as extra digits [1]. Only a few cases of this anomaly have been reported in the literature. Karchinov [1] reported six cases with associated hypoplasia or aplasia of the tibia. Hamanishi and colleagues [2] reported a case of diplopodia w...

Jason-1 / Jason-2 metocean comparisons and monitoring

The initial tandem phase of the Jason-2 mission is important for the calibration of the entire altimetric system, not just the records of sea surface height. However, as well as allowing a bulk comparison of metocean parameters such as wave height and backscatter strength (used to infer wind speed), it affords a more detailed opportunity to understand the artefacts within each instrument. The w...
