Creating Structured PDF Files Using XML Templates
This paper describes a tool for recombining the logical structure from an XML document with the typeset appearance of the corresponding PDF document. The tool uses the XML representation as a template for the insertion of the logical structure into the existing PDF document, thereby creating a Structured/Tagged PDF. The addition of logical structure adds value to the PDF in three ways: the accessibility is improved (PDF screen readers for visually impaired users perform better), media options are enhanced (the ability to reflow PDF documents, using structure as a guide, makes PDF viable for use on hand-held devices) and the re-usability of the PDF documents benefits greatly from the presence of an XML-like structure tree to guide the process of text retrieval in reading order (e.g. when interfacing to XML applications and databases)
DLR equations and rigidity for the Sine-beta process
We investigate Sine, the universal point process arising as the
thermodynamic limit of the microscopic scale behavior in the bulk of
one-dimensional log-gases, or -ensembles, at inverse temperature
. We adopt a statistical physics perspective, and give a description
of Sine using the Dobrushin-Lanford-Ruelle (DLR) formalism by proving
that it satisfies the DLR equations: the restriction of Sine to a
compact set, conditionally to the exterior configuration, reads as a Gibbs
measure given by a finite log-gas in a potential generated by the exterior
configuration. Moreover, we show that Sine is number-rigid and tolerant
in the sense of Ghosh-Peres, i.e. the number, but not the position, of
particles lying inside a compact set is a deterministic function of the
exterior configuration. Our proof of the rigidity differs from the usual
strategy and is robust enough to include more general long range interactions
in arbitrary dimension.Comment: 46 pages. To appear in Communications on Pure and Applied Mathematic
The Journey of a Specimen: a Blogging Campaign for the KU Natural History Museum
The KU Natural History Museum has a staggering collection of over 8 million biological specimens. This project attempts to demonstrate how to bring this collection closer to the public via photos and text presented on the museum's blog. To produce a prototype for future publications, existing museum websites and blogs were reviewed and literature on web audiences was evaluated. The investigator built content for the prototype by collecting images and text through a trip to Peru, conducting interviews with significant researchers, and taking photographs of a sample of the museum's collection. The final prototype for the project included eight posts which demonstrate an organization scheme in which content was divided into two subsections - the journey of a specimen from the field to the lab, and the usefulness of a group of specimens once put into the collection

The Marginal Cost of Natural Gas Distribution Pipelines: The Case of Société en Commandite Gaz Métropolitain, Québec
Investment expenditures in natural gas distribution pipelines account for 70% of the rate base of Société en Commandite Gaz Métropolitain (SCGM), the natural gas utility which serves most customers in the province of Québec. In allocating these costs to rate payers, the regulatory process divides costs into an access fee which reflects the fixed costs of planning and implementing the system that is to be divided equally over all users and a user or variable cost fee reflecting the capacity they use. In this paper we estimated a cost function to provide information to regulators on how these tariffs should be set. We use a unique data set of 131 observations which represent natural gas extension projects realized by SCGM in four Québec regions (Trois-Rivières, Sherbrooke, Québec and Chicoutimi) in the eighties and early nineties, to analyze the main determinants of capital costs. It is found that capital cost is not separable into a fixed and a variable component, that the elasticity with respect to maximum daily demand is not significant, and that the elasticity with respect to pipe length is slightly less than one. Maximum daily demand by each consumer class and consumer density per kilometer play no statistically significant role.
Multifractal analysis of Birkhoff averages for countable Markov maps
In this paper we prove a multifractal formalism of Birkhoff averages for
interval maps with countably many branches. Furthermore, we prove that under
certain regularity assumptions on the potential the Birkhoff spectrum is real
analytic. Applications of these results to number theory are also given.
Finally, we compute the Hausdorff dimension of the set of points for which the
Birkhoff average is infinite.Comment: 27 pages. Substantial changes have been made to Theorem 1.2 and

Assembling States: Community Formation And The Emergence Of The Inca Empire
This dissertation investigates the processes through which the Inca state emerged in the south-central Andes, ca. 1400 CE in Cusco, Peru, an area that was to become the political center of the largest indigenous empire in the Western hemisphere. Many approaches to this topic over the past several decades have framed state formation in a social evolutionary framework, a perspective that has come under increasing critique in recent years. I argue that theoretical attempts to overcome these problems have been ultimately confounded, and in order to resolve these contradictions, an ontological shift is needed. I adopt a relational perspective towards approaching the emergence of the Inca state – in particular, that of assemblage theory. Treating states and other complex social entities as assemblages means understanding them as open-ended and historically individuated phenomena, emerging from centuries or millennia of sociopolitical, cultural, and material engagements with the human and non-human world, and constituted over the longue durée.
This means that understanding the emergence of the Inca state, and the historically contingent form it took, requires investigating the transformations of local and regional communities in the Cusco heartland. The multiscalar nature of this type of investigation also demands an examination of processes occurring at particular local communities through time. To resolve this, I directed excavations at the archaeological site of Minaspata, located in the Lucre Basin in the southeastern part of the Cusco region, followed by analyses of the material remains recovered from the site. These include fine-grained investigations of the ceramic patterns, the faunal and macrobotanical remains, and the procurement of obsidian through long-distance exchange. By comparing these patterns to those of the larger Cusco region, an understanding of how the Cusco regional community cohered and broke apart at various points in time can be gained. This regional community eventually gave rise to the Inca state, providing the raw material for Inca projects of sovereignty and subject-making. Although the period before Inca emergence was marked by processes focused on the localization of community, the sociocultural and material frameworks established through complex histories of interaction over millennia enabled the Cusco region to reproduce itself as a self-recognizing, coherent social entity, a critical necessity for the emergence of Inca sovereignty
A Critical Study of William Nevill\u27s The Castell of Pleasure; the Delusions of Amor.
Few English poems have been neglected more than William Nevilll\u27s The Castell of. Pleasure. Following Henry Pepwell\u27 s reprint ( 1518) of Wynkyn de Worde\u27 s original edition, the poem has been reprinted only twice. Scholarly criticism of the poem is even rarer than are its editions
