Innovative Inert Matrix-Thoria Fuels for in-Reactor Plutonium Disposition
No full textThe present leading option for plutonium disposition, either civilian or weapons Pu, is to burn it in LWRs after having converted it to MOX fuel. However, among the possible types of fuel which can be envisaged to burn plutonium in LWRs, innovative U-free fuels such as inert matrix and thoria fuel are novel concept in view of a more effective and ultimate solution from both security and safety standpoint. Inert matrix fuel is an non-fertile oxide fuel consisting of PuO2, either weapon-grade or reactor-grade, diluted in inert oxides such as for ex. stabilized ZrO2 or MgAl2O4, its primary advantage consisting in no-production of new plutonium during irradiation, because it does not contain uranium (U-free fuel) whose U-238 isotope is the departure nuclide for breeding Pu-239. Some thoria addition in the matrix (thoria-doped fuel) may be required for coping with reactivity feedback needs. The full thoria-plutonia fuel though still a U-free variant cannot be defined non-fertile any more because the U-233 generation. The advantage of such a fuel option consisting basically on a remarkable already existing technological background and a potential acceleration in getting rid of the Pu stocks

Whose thumb is it anyway? Classifying author personality from weblog text
No full textWe report initial results on the relatively novel task of automatic classification of author personality. Using a corpus of personal weblogs, or ‘blogs’, we investigate the accuracy that can be achieved when classifying authors on four important personality traits. We explore both binary and multiple classification, using differing sets of n-gram features. Results are promising for all four traits examined.
Making biggest bigger: Port Metro Vancouver's 21st century re-structuring -- global meets local at the Asia Pacific Gateway
No full textVancouver's Port is Canada's biggest. On January 1, 2008, it got bigger — restructuring the Port of Vancouver, the Fraser River Port Authority and the North Fraser Port Authority, into a single Vancouver Fraser Port Authority, marketed (as of June, 2008) as Port Metro Vancouver.[1] This new entity was the culmination of a process of divestiture, re-organizational adjustment, shift to market orientation and consolidation that has played out over several decades across Canada's ports. This article examines some of this recent history — both in terms of (i) divestiture and increased market orientation and (ii) more recently, major port consolidation — and governmental responses to ensure Vancouver remains Canada's busiest port and a central part of the country's Asia-Pacific Gateway and Corridor Initiative.

Differentiating Document Type and Author Personality for Linguistic Features
No full textThere are many ways to profile a collection of documents. This paper presents highlight from a body of work that has looked at individual differences in the language of personal weblogs. Firstly, we present a measure of linguistic contextuality that can be used to profile and rank genres. When applied to weblogs, we will show they are similar to school essays, yet significantly less contextual than e-mail. We then look at individual variation of language, as due to the personality of the author. We show that with just a few linguistic features, it is possible to explain significant proportions of variance within personality traits
