Lightning Prediction for Australia Using Multivariate Analyses of Large-Scale Atmospheric Variables

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Large Scale NVH analyses for General Motors Using Cray SV1

MSC.Nastran V70.7 was used on the Cray SV1 to perform large-scale NVH problems typically encountered in the automotive industry. Several MSC.Nastran solution sequences such as SOL 103, 111, 108, and 107 are heavily used by automotive customers in a production environment on the Cray SV1. Significant performance improvements were recently made to key MSC.Nastran kernels to exploit the architectu...

Improved atmospheric modelling for large scale high-precision positioning based on GNSS CORS networks in Australia

This contribution describes a recent Australian Research Council (ARC) project funded under the ARC-Linkage Scheme. The research team comprises researchers from RMIT University, UNSW, University of Melbourne, Spatial Information Infrastructure and the Department of Lands, NSW. The aim of the project is to enhance the utility of continuously operating reference station (CORS) networks in the sta...

Multivariate Hawkes Processes for Large-Scale Inference

In this paper, we present a framework for fitting multivariate Hawkes processes for large-scale problems, both in the number of events in the observed history n and the number of event types d (i.e. dimensions). The proposed Scalable LowRank Hawkes Process (SLRHP) framework introduces a lowrank approximation of the kernel matrix that allows to perform the nonparametric learning of the d trigger...
