I am delighted to report that Fan Zhu's external examiners were pleased with his thesis and his spirited viva defense. They have recommended a pass with a few minor corrections. A big thank you to Professors Gary Green and Richard Baldock.
Title:
Brain Perfusion Imaging - Performance and Accuracy
Within the EC project VERCE (Virtual Earthquake and seismology Research Community in Europe e-science environment) one of the challenges is providing to the scientists a framework that allows the integration of their scientific code within a streaming workflow system. In this context, the distribution of the data and the computational resources accessible during the execution of the workflow will definitely make the validation, reproducibility and traceability of the results more complicated.
During the recent OSDC meeting there was a lot of discussion about a (hopefully) "viral" application or approach to aid scientists by allowing them to use OSDC resources. dropbox was a frequently occurring example. Taking the direct approach, I prototyped a simple map-reduce box, which behaves like a dropbox but it can also accept special files or folders representing map-reduce jobs. All file/folder referencing is done in local terms, thus "cloudifying" the storage and map-reduce service.
The ability to analyze massive volumes of network traffic (several hundred Gbps) in real-time (with microsecond to sub-second latencies) is important for communication service providers as it enables them to optimize use of their service infrastructure and develop revenue-generating opportunities. In particular, the real-time analysis of perishable user traffic that is not stored due to regulatory and other constraints can provide insights that are useful in many applications.
