Revisiting revisitation in computer interaction: organic bookmark management
No full textAccording to Milic-Frayling et al. (2004), there are two general ways of user browsing i.e. search (finding a website where the user has never visited before) and revisitation (returning to a website where the user has visited in the past). The issue of search is relevant to search engine technology, whilst revisitation concerns web usage and browser history mechanisms. The support for revisitation is normally through a set of functional built-in icons e.g. History, Back, Forward and Bookmarks. Nevertheless, for returning web users, they normally find it is easier and faster to re-launch an online search again, rather than spending time to find a particular web site from their personal bookmark and history records. Tauscher and Greenberg (1997) showed that revisiting web pages forms up to 58% of the recurrence rate of web browsing. Cockburn and McKenzie (2001) also stated that 81% of web pages have been previously visited by the user. According to Obendorf et al. (2007), revisitation can be divided into four classifications based on time: short-term (72.6% revisits within an hour), medium-term (12% revisits within a day and 7.8% revisits within a week), and long-term (7.6% revisits longer than a week
DIPOLE STABILIZING RODS SYSTEM FOR A FOUR-VANE RFQ : MODELING AND MEASUREMENT ON THE TRASCO RFQ ALUMINUM MODEL AT LNL
No full textThe Dipole Stabilizing Rods (DSR’s) are devices
used in order to reduce a priori the effect
of perturbation on the operating mode of
a four-vane RFQ caused by neighboring dipole modes by increasing the frequency spacing between the TE210 mode
and dipole modes, without, in principle, affecting the quadrupole TE210 mode. They have proven to be particularly
useful in the case of coupled RFQ’s whose overall length is significantly greater than the operatingwavelength. In this
article we present a circuit model of such DSR’s, that, used in combination with a transmission line model of a four
vane RFQ, has allowed us to predict the dimensioning of the DSR’s in the case of the aluminum model of TRASCO
RFQ. The DSR parameters and, in general, the accuracy of the model have been also confirmed by HFSS simulations
and by RF measurements on the above-mentioned model
Normalized Power Prior Bayesian Analysis
No full textThe elicitation of power prior distributions is based on the availability of historical data, and is realized by raising the likelihood function of the historical data to a fractional power. However, an arbitrary positive constant before the like- lihood function of the historical data could change the inferential results when one uses the original power prior. This raises a question that which likelihood function should be used, one from raw data, or one from a su±cient-statistics. We propose a normalized power prior that can better utilize the power parameter in quantifying the heterogeneity between current and historical data. Furthermore, when the power parameter is random, the optimality of the normalized power priors is shown in the sense of maximizing Shannon's mutual information. Some comparisons between the original and the normalized power prior approaches are made and a water-quality monitoring data is used to show that the normalized power prior is more sensible.Bayesian analysis, historical data, normalized power prior, power prior, prior elicitation, Shannon's mutual information.

Exporting empire: Africa, colonial officials and the construction of the British imperial state, c.1900?39
No full textFor Africans, rank and file colonial officials were the most visible manifestation of British imperial power. But in spite of their importance in administering such vast imperial territories, the attitudes of officials who served between the end of the nineteenth century and the Second World War, as well as what shaped such attitudes, have yet to be examined in any systematic way.In this original and revisionist work, Prior draws upon an enormous array of private and official papers to address some key questions about the colonial services. How did officials’ education and training affect the ways that they engaged with Africa? How did officials relate to one another? How did officials seek to understand Africa and Africans? How did they respond to infrastructural change? How did they deal with anti-colonial nationalism? This work will be of value to students and lecturers alike interested in British, imperial and African history
