Acknowledgements I would like to extend my gratitude to my supervisor Sam Howison for his guidance and advice throughout the preparation and writing of this dissertation. I would also like to thank Christoph Reisinger for his advice whilst Dr Howison was away. Finally and most importantly I would like to thank my parents for their continued emotional and financial support, without which I would...

Sir, I was recently on call for nephrology, and something happened. I was rung by a first year junior doctor at 1 am, saying that a patient's 'MEWS score was 6'. The patient had had a renal transplant that day. A score of 6 is very high. It should trigger a rapid senior review, and possible intensive care re-ferral. Modified early warning score (MEWS) is an electronic early warning score based ...

This paper presents a methodology for determining the optimal portfolio allocation demand response aggregator. The formulation is based on Day-Ahead electricity prices, in which aggregator coordinates set of residential consumers that are recruited through contracts. Four types contracts analyzed, considering both direct and indirect programs. objective to compare different scenarios contract p...

We generalize the results of Satopää et al. (2014, 2015) by showing how the Gaussian aggregator may be computed in a setting where parameter estimation is not required. We proceed to provide an explicit formula for a “one-shot” aggregation problem with two forecasters.

David B. Kirk'" We have designed, fabricated, and tested an analog VLSI chip which computes radial basis functions in parallel. We have developed a synapse circuit that approximates a quadratic function. We aggregate these circuits to form radial basis functions. These radial basis functions are then averaged together using a follower aggregator.

We examined Web 2.0 services that provide different levels of knowledge exploitation and developed a framework for classifying existing service models from a knowledge-creation perspective. More than 1000 Web 2.0 application sites were analyzed and classified. We termed the two types of service platforms: Experience-Socialization and Intelligence-Proliferation. These involved four types of serv...

Deal sites are widely used for some time and there is a growing body of knowledge on them. There exists literature on infomediaries. But there is a gap when it comes to infomediaties focused on deal sites, i.e. aggregators of deal site offers. The research focused on impact of Big Five Inventory personality traits on whether respondents prefer visiting individual deal sites, or aggregators, or ...

This paper examines the development of web aggregators, entities that collect information from a wide range of sources, with or without prior arrangements, and add value through post-aggregation services. New Web-page extraction tools, context sensitive mediators, and agent technologies have greatly reduced the barriers to constructing aggregators. We predict that aggregators will soon emerge i...
