Many practical problems require estimating future values of a Positive Definite matrix from past historical data. While several models have been proposed in the literature for propagating past data in this context, the problem of identifying these models from experiments is largely open. The main result of this paper is an efficient convex optimization based algorithm for identifying a class of models...
As the computing technology develops, micro-simulation becomes more and more important in the Intelligent Transportation Systems (ITS) research, because it can provide detailed descriptions of the system. However, for a multi-agent systems (MAS) modelling of an ITS, the computation burden is large, as it involves the computation of the state changing of all the agents. Further, if we consider simulation...
We have developed techniques to automatically generate personalised biomechanical models of patients' hearts based on 3D cardiac images. We demonstrate this approach using multi-slice computed tomography images. Unsupervised segmentation was performed using non-rigid image registration with a segmented image. A finite element model was automatically fitted to the segmented data of the left ventricle...
Magnetic Resonance Spectroscopy (MRS) is a non-invasive technique in which biochemical information can be obtained in vivo. LCModel and QUEST are two quantization tools for magnetic resonance spectroscopy. In this paper, a comparison between LCModel and QUEST is presented. After a description of the methods, we compared their performance on quantification of dominant metabolites in the brains of a...
