It is well accepted that ontology is useful for personalized Web information gathering. However, it is challenging to use semantic relations of "kind-of", "part-of", and "related-to" and synthesize commonsense and expert knowledge in a single computational model. In this paper, a personalized ontology model is proposed attempting to answer this challenge. A(More)
We present a novel method of contact modelling for discrete deformable models. Our algorithm is used to simulate contact between rigid surgical tools of arbitrary shape and deformable virtual organs bounded by triangular mesh surfaces. It uses a divide and conquer strategy to redistribute an arbitrary field of displacements on organ surfaces into an(More)
The commercial real estate industry is currently in a state of turmoil, as access to capital markets is as constrained as consumer demand. Today many real estate development firms find themselves in difficult positions, with plummeting net operating income and upwardly mobile capitalization rates. Tail events – market events that were believed, based on(More)
In this paper we present a technique for the modelling of realistic collisions between arbitrary rigid surgical tools and deformable geometry that is independent of the resolution of colliding objects. We use a spatial hash table to provide an efficient narrow-phase collision detection and modelling backend. This is combined with previous work on collision(More)

Canine intervertebral disc πherniation causes a naturally-occurring spinal cord injury (SCI) that bears critical similarities to human SCI with respect to both injury pathomechanisms and treatment. As such, it has tremendous potential to enhance our understanding of injury biology and the preclinical evaluation of novel therapies. Currently, there is(More)
This paper formulates the generic Machine Learning (ML) problem into finding the simplest spectral transform form (i.e. one having as many zero coefficients as possible) for an (in)complete binary function. The classical binary logic synthesis problem can be modeled to minimize a single output Boolean function with a two-level structure consisting of an(More)
Publishers have always been keen to maximize the multimedia potential of their products, and are increasingly eager to make the most of the opportunities afforded to them by digital platforms and technologies. While this sort of treatment is ubiquitous for those intellectual properties belonging to industry behemoths Marvel and DC, it is unusual for those(More)
