such as ADSL <strong>and</strong> FTTH, we are now about to enter a ubiquitous communications age in which it will be possible to exchange<br />
information with anyone at anytime, anywhere. As a result, information <strong>and</strong> communications services are becoming an<br />
essential element of our daily societal infrastructure. Today, information <strong>and</strong> communications technology, involving, for<br />
example, fixed <strong>and</strong> mobile phones, Internet search <strong>and</strong> information exchange, <strong>and</strong> electronic payment, is already deeply woven<br />
into society, mirroring the historical integration of electricity, water <strong>and</strong> sewerage, gas, <strong>and</strong> public transport into our daily lives.<br />
Unfortunately, as a result of this integration, computer viruses <strong>and</strong> other malicious data operations are now capable of breaking<br />
into PCs <strong>and</strong> databases <strong>and</strong> causing significant disruptions. Given the increasing scale of cyber attacks, wide-area information<br />
network infrastructures are growing more vulnerable.<br />

Preparing PNNL <strong>Reports</strong> with LaTeX<br />
Waichler, S. R.; Jun. 2005; 60 pp.; In English<br />
Report No.(s): DE2005-15016481; PNNL-15197; No Copyright; Avail.: National <strong>Technical</strong> Information Service (NTIS)<br />
LaTeX is a mature document preparation system that is the st<strong>and</strong>ard in many scientific <strong>and</strong> academic workplaces. It has<br />
been used extensively by scattered individuals <strong>and</strong> research groups within PNNL for years, but until now there have been no<br />
centralized or lab-focused resources to help authors <strong>and</strong> editors. PNNL authors <strong>and</strong> editors can produce correctly formatted<br />
PNNL or PNWD reports using the LaTeX document preparation system <strong>and</strong> the available template files. In LaTeX, document<br />
content is maintained separately from document structure for the most part. This means that the author can easily produce the<br />
same content in different formats <strong>and</strong>, more importantly, can focus on the content <strong>and</strong> write it in a plain text file that doesn’t<br />
go awry, is easily transferable, <strong>and</strong> won’t become obsolete due to software changes. LaTeX produces the finest print quality<br />
output; its typesetting is noticeably better than that of MS Word. This is particularly true for mathematics, tables, <strong>and</strong> other<br />
types of special text. Other benefits of LaTeX: easy h<strong>and</strong>ling of large numbers of figures <strong>and</strong> tables; automatic <strong>and</strong> error-free<br />
captioning, citation, cross-referencing, hyperlinking, <strong>and</strong> indexing; excellent published <strong>and</strong> online documentation; free or<br />
low-cost distributions for Windows/Linux/Unix/Mac OS X. This document serves two purposes: (1) it provides instructions<br />
to produce reports formatted to PNNL requirements using LaTeX, <strong>and</strong> (2) the document itself is in the form of a PNNL report,<br />
providing examples of many solved formatting challenges. Authors can use this document or its skeleton version (with<br />
formatting examples removed) as the starting point for their own reports.<br />

TREC-6 Interactive Track Report. Part 1: Experimental Procedure <strong>and</strong> Initial Results<br />
Byrd, Don; Swan, Russell; Allan, James; Jan. 1, 2005; 34 pp.; In English<br />
Report No.(s): AD-A440416; No Copyright; Avail.: Defense <strong>Technical</strong> Information Center (DTIC)<br />
The TREC-6 Interactive Track concentrated on Aspect-Oriented Retrieval: finding at least one document that covers each<br />
aspect of relevance to a given topic as opposed to the usual information-retrieval task of simply finding documents containing<br />
as much information as possible about the topic. For this track, we at the Center for Intelligent Information Retrieval of the<br />
University of Massachusetts designed <strong>and</strong> ran our first-ever user study.<br />

This research report presents a novel strategy to develop a sensor model based on a probabilistic approach that would<br />
accurately provide information about individual sensor’s uncertainties <strong>and</strong> limitations. The strategy also establishes the<br />
dependence of sensor’s uncertainties on some of environmental parameters or parameters of any feature extraction algorithm<br />
used in estimation based on sensor’s outputs. The approach makes use of a neural network that is trained with the help of an<br />
