Abstract
We focus in this paper on object recognition using a new type of kernel referred to as "context dependent.” Objects, seen as constellations of interest points, are matched by minimizing an energy function mixing 1) a fidelity term which measures the quality of feature matching, 2) a neighborhood c...

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (368)1925 2010
Abstract
We discuss the use of a parametric modelling toolkit, called Nimrod, that makes it possible both to explore model behaviour as parameters are changed and also to tune parameters by optimizing model output. Importantly, Nimrod leverages computers on the Grid, accelerating experiments by using availab...

Abstract
The experience sampling method (ESM) represents a valuable way of assessing clinical phenomena in real world settings and across time. Despite its theoretical advantages, using this methodology in psychiatric populations is challenging. This paper acts as a guide to researchers wishing to employ this...

Abstract
The bidomain equations are frequently used to model the propagation of cardiac action potentials across cardiac tissue. At the whole organ level, the size of the computational mesh required makes their solution a significant computational challenge. As the accuracy of the numerical solution cannot b...

Participants in the vibrotactile group took 4.08 min (95% CI = 1.22) to deliver definitive treatment compared with 7.21 min (95% CI = 2.07) for the control group (P < 0.05). Despite the reduced time to treatment, no improvement in SA was measured. CONCLUSION: Our study provides evidence that vibrota...
