ABOUT CYBERPOSIUM
Cyberposium is the premier MBA high technology conference, uniting each year industry leaders, MBA students and academics to interactively explore and share the latest provocative thoughts on technology and business innovation. Since 1996 over 1,000 participants converge on the Harvard Business School campus every year to participate in Cyberposium
Search Visionary Panel
Historically search has meant the ability to conduct web searches on primarily text data. Convergence in search will give us the ability to find answers to queries no matter where and in what form the data resides. The demarcation between the on-line and the off-line world will be blurred as more and more information is digitized. At the same time, the ability to search through diverse media like image, video and audio will allow new applications to be built. What are some of the killer applications that will emerge? Who are likely to be the winners and losers in this changing landscape?

, St. Pete Beach, Florida
Speaker: Santokh BadeshTitle of the talk:
Title: "Material Challenges in Component Designs for Marking Subsystems"
Abstract
"This presentation will describe the work process to develop new materials and enabling surfaces that provide improved subsystem performance in marking. These subsystems include image generation, charging, development, cleaning, transfer, and fusing. The needs for high quality color, high speed, long life & low cost, substrate latitude, and environmental friendliness demand continuing improvement of all Xerographic marking subsystems. To provide these improvements requires development of new materials which form these functional surfaces.
In the first part of the talk, I will describe the role of surfaces in general and work process to develop enabling components for marking subsystems. This process begins with new subsystem requirements. These are translated into proposed new material properties. New materials are designed and tested, and prototype components are fabricated and fixture/machine tested. The process is iterated until the required performance is achieved.
The second part I will show specific examples describing the development of surfaces (belts and rolls, brushes, blades etc) for these subsystems. The major emphasis will be placed on what is needed for performance optimization. The conclusions will point out to the need for iterative optimization of both materials properties and subsystem designs. Familiarity with this process will enable materials scientists and subsystem engineers to collaborate as a team for developing high performance marking engines"

American Physical Society March Meeting
March 21 - 26
, Los Angeles, CA
Topic: Surfaces of Abraded Fluoroelastomer Nanocomposites
Speaker: D. Pan, Wilson Center for Research & Technology
Abstract: Stiffening or reinforcement of elastomer with a second hard particle phase to produce a networked or crosslinked composite is common in applications of high-performance elastomers. The average size of reinforcing particle is frequently in the range of a few tenths to several microns, the shape from spheres to cylinders of high aspect ratio, and the particle concentration can be as high as about 50% by weight partly because of ease of dispersing a small number of large particles. One of the main problems with micro-filled fluoroelastomer surfaces is the continuous removal of large particles by abrasion and wear resulting in large pits or surface defects under an extreme, tribological environment. Furthermore, these large pits can lead to a roughened surface. The aim of this work is to investigate the influence of nano-particles versus micro-particles on the surface defect size and density of filled fluoroelastomer. We applied scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX), and surface roughness measurement to examine the surfaces of paper abraded fluoroelastomer nanocomposites. Qualitatively, SEM images show the surface defect size or density of nanocomposites is generally reduced, as compared to that of fluoroelastomer microcomposites. On a somewhat larger scale, it is found that the surface roughness (Ra) of paper abraded nanocomposites can be controlled to less than 0.2 to 0.3 microns.

March 21 - 26
, Santiago de Compostela, Spain
"A probabilistic interpretation of precision, recall and F-score, with implication for evaluation"
Authors: Cyril Goutte, Eric Gaussier
Abstract : "We address the problem of 1/ assessing the confidence of the standard point estimates, precision, recall and F-score, and 2/ comparing the results, in terms of precision, recall and F-score, obtained using two different methods. To do so, we use a probabilistic setting which allows us to obtain posterior distributions on these performance indicators, rather than point estimates. This framework is applied to the case where different methods are run on different datasets from the same source, as well as the standard
situation where competing results are obtained on the same data."

AAAI'05 Spring Symposium on Knowledge Collection from Volunteer Contributors (KCVC05)
March 21 - 26
, Stanford University
Authors: Michel Simard, Elliott Macklovitch
Topic: "Studying the human translation process through the transSearch log-files"
Abstract: This paper presents the TransSearch log-files. These are records of interactions between human translators and TransSearch, a bilingual concordancing system. The authors show how this data can be used as experimental evidence to study the translation process. This is exemplified by the results of a study on the nature of the text units on which human translators operate based on this data. Finally, some enhancements to the TransSearch system are proposed, aiming both at improving its usefulness for the end-users and the quality of the data that can be collected from its log- files.

Topic: Substituted indolo[3,2-b]carbazoles: A new class of stable, high mobility organic semiconductors for thin film transistors
Speakers: Yuning Li, Yiliang Wu, Beng Ong*
Materials Design & Integration Laboratory
Xerox Research Centre of Canada
Mississauga, Ontario, Canada L5K 2L1
e-mail: Beng.Ong@xrcc.xeroxlabs.com
Properly functionalyzed indolo[3,2-b]carbazoles represent a new class of stable, high-mobility organic semiconductors for thin-film transistors (TFTs). Both 5,11-disubstituted and peripherally substituted indolo[3,2-b]carbazoles with proper substituents self-organized into highly crystalline terrace-layered structures under suitable processing conditions. Organic TFTs using channel semiconductors of this nature exhibited excellent field-effect transistor properties, with mobility up to 0.15 cm2 V-1 s-1 and current on/off ratio to 107. By virtue of their relatively low HOMO levels and large band gaps, this class of semiconductors displayed excellent environmental stability under ambient conditions, an appealing characteristic for organic TFT applications.

First International Symposium on Semantic Mining in Biomedecine Symposium (SMBM)
April 10 - 14
, Cambridge, England
"Discovering paradigm shift patterns in biomedical abstracts: application to neurodegenerative diseases"
Authors: Aaron Kaplan, Agnes Sandor, Christine Chichester, Frédérique Lisacek,
Abstract: Millions of facts are stored within biological literature. Most of these facts represent small advances in the knowledge on an established theory, but a small fraction offer new insight into a biological phenomenon. We propose a method based on computational linguistic tools for distinguishing these facts (extraction) and exposing knowledge that may be important in future developments (prediction). The method is based on finding linguistic cues indicating that the authors of biological articles have identified a problem with, or a break from, conventional knowledge.
Results: Starting with 40000 reports on neurodegeneration published between 1996 and 2003, we used our system to select and rank 3700 documents from which we compiled a list of proteins involved in neurodegenerative diseases that compares with very recent review articles and with on-line protein networks

IS&T 2005 Archiving Conference
April 26 - 30
, Washington, DC
Introduction to Archiving 2005
We are pleased to announce the program for the Second IS&T Archiving Conference. The 2005 conference looks to build on the success of the first and on the enthusiasm it created. The first conference brought together a diverse group of attendees from academia, industry, museums, libraries, government institutions, and not-for-profit organizations. We expect the second to do the same and further the goal of building a unique international community that brings together multiple organizations and specialties in the domain of archiving and preservation.
Some features of the second conference will be familiar to those who attended the first. The technical papers program is again arranged in a single-track format to promote the interchange of information across specialties in the field.
We will start each day with a keynote address; this year's speakers will be Deanna Marcum, associate librarian for library services, Library of Congress on "The Views of Archiving from the Library of Congress;" Clifford A. Lynch, Executive Director of the Coalition for Networked Information on "Archiving, Stewardship, Curation: From the Personal to the Global Sphere;" and Helen Shenton, Head of Collection Care at the British Library on "Real Time, Deep Time, Life Time - Spanning Digital and Traditional Collections Life Cycles."
As with most IS&T conferences, the Interactive Poster session is a key feature, providing the opportunity for presenters and attendees to mingle and discuss results presented using a variety of media formats. The Interactive Poster Session authors will have the opportunity to introduce their work through 90 second "spotlight" talks at the beginning of the session.
Another important feature of the program is the tutorials, which are organized into three tracks and offered on Tuesday, the day before the papers program. The tracks are "Formats and Metadata," "Imaging Science and Archiving Infrastructure," and "Media and Storage." You may choose to follow a single track all day or personalize your course program to meet your educational or professional needs.
Special events are planned as well. The Conference Reception will be held Wednesday evening; Late Breaking News Session will close the papers program Friday afternoon; and "Behind the Scenes" tours of imaging and archiving facilities in the DC area are being arranged for Friday afternoon after the conference concludes.
An excellent tutorial program, outstanding keynote speakers, and a papers program with high-level speakers from around the world are waiting for you in Washington, DC. Please plan to join us for the Second IS&T Archiving Conference.

Metadata Extraction from Office Documents
William Stumbo and John Handley, Xerox Corporation
Abstract: Abstract: This paper focuses on using layout-based techniques to automatically extract metadata when scanning office documents to an archive. Many office documents such as letters, inter-office memos, and invoices contain key information that is spatially arranged. Information arrayed in this manner is easy for a reader to identify and understand. However, location of information within office documents varies greatly between documents, unlike forms where layout is static. This poses a challenge for layout based metadata extraction techniques. Our system uses regular expression matching and stochastic grammars on lines of text to efficiently and accurately label text according to function, enabling archived documents to be precisely retrieved.

27th International Conference on Software Engineering
May 15 - 22
, St. Louis, Missouri
Subject: Modeling Requirements for Combinatorial Software Testing
Speakers: S. Dalal Imaging and Services Technology Center Xerox Corporation 800 Phillips Road Webster, NY 14580; C. Lott, A. Jain Applied Research Area Telcordia Technologies, Inc. One Telcordia Drive Piscataway, NJ 08854
Abstract: The combinatorial approach to software testing uses models to gen¬erate a minimal number of test inputs so that selected combinations of input values are covered. The most common coverage criteria is two¬way, or pairwise coverage of value combinations, though for higher confidence three¬way or higher coverage may be required. This paper presents example system requirements and correspond¬ing models for applying the combinatorial approach to those re¬quirements. These examples are intended to serve as a tutorial for applying the combinatorial approach to software testing. Although this paper focuses on pairwise coverage, the discussion is equally valid when higher coverage criteria such as three¬way (triples) are used. We use terminology and modeling notation from the AETG1 system to provide concrete examples.

Coupling maximum entropy and probabilistic context-free grammar models for XML annotation of Documents
Boris Chidlovskii, Jérôme Fuselier
Abstract
we consider the problem of semantic annotation of semi-structured documents according to a target XML schema. The task is to annotate a document in a tree-like manner where the annotation tree is an instance of a tree class defined by DTD or W3C XML Schema description. In the probabilistic setting, we cope with the tree annotation problem as a generalized probabilistic context free parsing of an observation sequence where each observation comes with a probability distribution over terminals supplied by a probabilistic classifier associated with the content of documents. We determine the most probable tree annotation by maximizing the joint probability of selecting a terminal sequence for the observation sequence and the most probable parse for the selected terminal sequence. We extend the inside-outside algorithm for probabilistic context-free grammars and establish a Naive Bayes-like requirement that the content classifier should satisfy when estimating the terminal probabilities.

2nd McGill NanoEngineering Organic and Nano Electronics Workshop
May 30
, \Montreal, QC
Topic: Degradation Phenomena and Stabilization Approaches in Small-Molecule Organic Light Emitting Devices
Speaker: Hany Aziz, Xerox Research Centre of Canada
ABSTRACT:
The last three years witnessed the arrival of the first wave of display products based on organic light emitting devices (OLED) to the market-place. However, the relatively poor OLED stability has limited their use to applications that do not require a display lifetime beyond few thousand hours (e.g. hand-held electronic devices).
In general, the poor device stability can be attributed to extrinsic and intrinsic factors. Extrinsic (ambient-induced) degradation phenomena are relatively well understood, and can be effectively controlled by proper encapsulation, whereas intrinsic degradation remains illusive. At Xerox, a primary focus of our OLED research has been to address some of these challenges.
In this presentation, I will give an overview on the OLED stability problem and discuss some of the important findings and developments in this area, including some approaches to increase device stability.

Topic:"Traduction automatique statistique avec des segments discontinus"
Speakers: Nicola Cancedda, Bruno Cavestro, Marc Dymetman, Eric Gaussier, Cyril Goutte, Michel Simard, Kenji Yamada, Arne Mauser(Xerox Research Centre Europe)
Abstract:
This paper presents a phrase-based statistical machine translation method, based on non-contiguous phrases, i.e. phrases with gaps. A method for producing such phrases from a word-aligned corpora is proposed. A statistical translation model is also presented that deals with such phrases, as well as a training method based on the maximization of translation accuracy, as measured with the NIST evaluation metric. Translations are produced by means of a beam-search decoder. Experimental results are presented, that demonstrate how the proposed method allows to better generalize from the training data.

10th International Conference on Implementation and Application of Automata (CIAA) 2005
June 27 - 30
, Sophia-Antipolis, France
Topic: "A class of rational n-WFSM Auto-Intersections"
Andre Kempe, Jean-Marc Champarnaud, Franck Guingne, Florent Nicart (Xerox Research Centre Europe)
Abstract
Weighted finite-state machines with n tapes describe n-ary rational string relations. The join n-ary relation is very important regarding to application. It is shown how to compute it via a more simple operation, the auto-intersection. Join and auto-intersection generally do not preserve rationality. We define a class of triples(A,i,j) such that the auto-intersection of the machine A w.r.t. tapes i and j can be computed by a delay-based algorithm.
We point out how to extend this class and hope that it is sufficient for many practical applications

INCOSE 2005 -
July 10 - 16
, Rochester, NY
Speaker: Nathaniel Martin
Topic: Work Practice in Research: A Case Study
Abstract: Work practice analysis is a type of Ethnography that studies individual and group work. It has been developing at Xerox over the past 20 years. Recently, it was applied by a research group studying text mining. It showed flaws in the group's initial understanding of the problem and redirected the group's attention from classification to clustering. In addition, it led to the development of a novel approach to text mining. Further study showed that the novel approach is widely applicable. We describe work practice in general, then provide a case study of the application or work practice analysis to the gathering requirements for text mining. We conclude that work practice analysis in specific helps bridge academic results and industrial practice.

7th World Congress of Chemical Engineering
July 10 - 15
, Glasgow, Scotland
Topic: Lean Six Sigma and Design for Lean Six Sigma in Process Development
Speaker: George Liebermann
Abstract: "Six Sigma" and "Lean" have been developed separately and used successfully as business practices for quite a number of years. The overall scope of integrating the "Six Sigma" and "Lean" methodologies into "Lean Six Sigma" is to take advantage of improvements in quality and consistency (Six Sigma) as well as in speed and low cost (Lean) in a synergistic way. This quality and business management initiative provided many corporations the opportunity for introducing improvements in many areas of their enterprise. Process development, and specifically chemical process development is such an area, where the use of Lean Six Sigma (LSS) may bring significant improvements, but also challenges in its implementation. Design for Six Sigma (DfSS) has been developed in the last several years to bring the six sigma protocols and tool box to research and development. The paper discusses the above topics in some detail. A review is given on a two year experience in implementing black belt and green belt projects in a specialty chemicals/polymers process development environment. Case histories are presented and lessons learned are summarized.

IEEE International Workshop on Business Transformation: Towards a theory of business agility
July 19
, Munich, Germany
Topic: Total cost of ownership: issues around reducing cost of support in a manufacturing organization case
Speakers: Stefania Castellani, Antonietta Grasso, Jacki O'Neill, Peter Tolmie
Abstract: The notion of total cost of ownership (TCO) has become a particular focus of interest across a wide range of commercial and academic communities in recent years, because of the way it enlarges the understanding of what the real cost of technology amounts to, beside purchase cost. The dominant conception of TCO derives from a model created by Gartner Group that considers hard and soft costs that are distributed across three prime categories of acquisition costs, control costs and operational costs. In order to measure those, the so far proposed TCO metrics tend to be based upon conventional, abstract categories of cost as defined by accounting and management literatures. These categories rarely attend to what might be understood as a cost in the thick of the every day work of the actual members of an organisation that such categories might be applied to. Our own research presented in this paper augments the field primarily by focusing upon break-fix costs, but also by relating these to the wider issues in TCO. The goal within this has been to not just take costs for granted but rather to try to understand what something like break-fix amounts to in organisational life. This has been pursued by looking at the details of how costs arise and are reasoned about in actual working practice. From this we have then sought to understand what current barriers exist to the implementation of a successful break-fix strategy and what kinds of technologies might be designed to facilitate that success.

IJCAI, 19th International Joint Conference on Artificial Intelligence
July 30 - August 6
, Edinburgh, Scotland
Topic:A probabilistic learning method for XML annotation of documents
Speakers:Boris Chidlovskii, Jérôme Fuselier
Abstract: We consider the problem of semantic annotation of semi-structured documents according to a target XML Schema. The task is to annotate a document in a tree-like manner where the annotation tree is an instance of a tree class defined by DTD or W3C XML Schema descriptions. In the probabilistic setting, we cope with the tree annotation problem as a generalized probabilistic context-free parsing of an observation sequence where each observation comes with a probability distribution over terminals supplied by a probabilistic classifier associated with the content of documents. We determine the most probable tree annotation by maximizing the joint probability of selecting a terminal sequence for the observation sequence and the most probable parse for the selected terminal sequence. We extend the inside-outside algorithm for probabilistic context-free grammars and establish a Naive Bayes-like requirement that the content classifier should satisfy when estimating the terminal probabilities.
Topic:HTML-to-XML Migration by means of sequential learning and grammatical inference
Speakers:Boris Chidlovskii, Jérôme Fuselier
Abstract: We consider the problem of document conversion from the layout-oriented HTML into a semantic-oriented XML annotation. An important fragment of the conversion problem can be reduced to the sequential learning framework, where source tree leaves are labeled with XML tags. We review sequential learning methods developed for NLP applications, including the Naive Bayes and Maximum entropy. Then we extend these methods with the hidden markov model (HMM) that injects the transition probabilities into the leaf classification function. Finally, we address the issue of HMM topology. We adopt grammatical inference methods to induce the HMM topology and show how to extend the sequential learning methods accordingly. We test all methods on a particular conversion case and report the evaluation results.

, Salvador, Brazil
Topic:Learning from partially labelled data -- with confidence
Speaker:Eric Gaussier, Cyril Goutte
Abstract: In this paper, we propose a unifying treatment of several strategies for training mixture models from label-deficient data. After a review of different approaches to estimating classification models on partially labelled data using mixture models, we identify a number of problems which lead us to propose a new EM variant. The aim is to better handle unlabelled data and provide a more confident discrimination decision. This is illustrated by an experimental comparison of the different models on the Leptograpsus crab data.

Abstract: We present a document understanding system in which
the arrangement of lines of text and block separators within
a document are modeled by stochastic context free grammars.
A grammar corresponds to a document genre; our
system may be adapted to a new genre simply by replacing
the input grammar. The system incorporates an optical
character recognition system that outputs characters, their
positions and font sizes. These features are combined to
form a document representation of lines of text and separators.
Lines of text are labeled as tokens using regular
expression matching. The maximum likelihood parse of this
stream of tokens and separators yield a functional labeling
of the document lines. We describe business card and business
letter applications.

Finite State Methods and Natural Language Processing 2005
September 1 - 3
, Helsinki
Topic:German compound analysis with wfsc
Speaker: Anne Schiller
Abstract: Compounding is a very productive process in German to form complex nouns or adjectives which represent about 7% of the words of an average newspaper text. Unlike English, German compounds do not contain spaces or other word boundaries, and the automatic analysis is often ambiguous. A (unweighted) finite-state morphological analyzer provides all potential segmentations for a compound without any filtering or prioritization of the results. The paper presents an experiment of analyzing German compounds with the Xerox Weighted Finite-State Compiler (wfsc) and it will show the advantage of using weighted finite-state transducers over simple FSTs.

Third International Conference on Business Process Management
September 6 - 8
, Nancy, France
Speaker: Tong Sun
Abstract: Abstract. Production printing workflow is a high-volume and high-speed printing process normally consisting of a set of complex and inter-related tasks namely pre-press, press and post-press procedures. Today many production printing vendors are increasingly offering heterogeneous devices and related software products that autonomously interoperate as a production printing workflow in a digital distributed environment. It is highly desirable in such environment that a detailed workflow assessment is performed either prior to the deployment or during real-time operations. A formal workflow model and assessment capability would ultimately benefit the customers who directly manage these production printing workflows to make better-informed decisions, understand the efficiency of to-be-purchased or already-deployed workflows, foresee the performance implications under a variety of business conditions. Therefore in this paper, we have developed formal workflow models (in both abstract and execution) based on the colored Petri nets [4] that incorporate production printing semantics. Based on these formal representations, we show how a production printing workflow can be assessed both analytically and quantitatively by leveraging existing Petri net tools.

IEEE International Conference on Image Processing
September 11 - 15
, Genova, Italy
Topic: Factors Influencing Psycophysically Valid Taxonomies of Image Texture
Abstract:Image texture is important in human and machine vision. A taxonomy of image texture that classifies textures the same way humans do psychophysically can be used in many fields. This paper deals with one attribute of texture, namely orderliness. To determine what underlying factors influence humans to perceive orderliness in textures, psychophysical direct magnitude estimation ratings of the orderliness of 27 Brodatz images were collected from 44 subjects. The images: a) were either tiled, locally oriented, or granular, b) had large, medium, or small scale elements, and c) contained either high, medium, or low regularity. Multidimensional scaling revealed three underlying factors that determined the perception of texture orderliness: uniformity of element shape and distribution, element size, and element dimensionality. Some of these results contradict predictions made by earlier computational models of texture. Such models should be revised to incorporate the results of our experiment.

Topic: Using real-life troubleshooting interactions to inform self-assistance design
Speakers:Jacki O'Neill, Antonietta Grasso, Stefania Castellani, Peter Tolmie
Abstract: End users facing technical problems with machinery, as for example computers and printers, can be assisted by systems that guide them toward an autonomous solution of the problem. Systems that can be offered to them are wide in range, but typically follow either in the category of Expert Systems or in the category of searchable databases that can be queried with keyword searches. Both approaches present advantages and disadvantages in terms of flexibility to address different levels of user expertise and ease of maintenance, however few studies explicitly address the issue of how best to design the balance between guidance and user freedom in such systems. In the work presented here an office equipment call centre has been studied in order to understand which kind of mechanisms are used when a human agent is guiding the user toward the resolution. The overall aim being not at reproducing the agent behaviour exactly in a system, rather at identifying which interaction building blocks such a system should have. A critical analysis of an existing knowledge base is also presented together with ethnographic observation in order to further exemplify the user study findings.

Topic: Materials for Digital Printing
Abstract: With the advancement in microprocessors and nano-technologies, non-impact printing has transitioned from analog to digital and is migrating from monochrome to color. The digital color-printing offerings have extended from home and office up to the production-printing segment. Digital color printing technologies have continually evolved in an effort to meet the intense customer demand for lower price per page, greater reliability/image quality, and a broad range of applications. These advances could not have been made without the critical role that xerographic materials have played. Life extensions with the ability to achieve high toner transfer efficiency and cleanability for photoreceptor and intermediate transfer belt has been an intense focus in this industry. The rapid expansion of chemical toner technologies has enabled new applications and offered new opportunities. This talk reviews the market trends in printing, the technological challenges of meeting the market requirements, and the material developments, which have supported the digital color printing advances.
Topic: Abrasion Resistance Comparison of Various Printing Technologies, Substrates, and Markets
Speaker: Shu Chang
Abstract: Abstract
The ability of a printed image to remain intact in an abrasive environment is essential in some applications. These prints must not suffer deletions, smudges, and colorant transfer due to rubbing or abrasion during the print's life under various usage conditions.. For example, book covers or bar codes must have higher resistance than magazines or brochures since they are subjected to significantly greater abrasive environments and for longer periods of time. In this study, we have examined a wide variety of printed matters using a GA-CAT Comprehensive Abrasion Tester. We have compared liquid toner prints and powder xerographic prints against lithographic prints made for different applications, such as magazines, brochures, specialty printing, labels, bar codes and book covers. We have identified different types of abrasion failures.
Speaker: Palghat Ramesh
Title: Quantification of toner aging in two component development systems
Abstract: Xerographic toners are typically blended with additives for adhesion control in development and transfer processes. 10-100 nanometer size additives on toner surface are used to space toners away from the electrode surfaces which lower the adhesion forces. However, in a developer housing, additives get buried into the toner over time due to the repeated mechanical stresses encountered. This is referred to as toner aging. Aged toners can have significantly higher adhesion forces and often perform poorly in development and transfer. In this paper, we will discuss models for estimating the surface additive coverage distribution on toners in the developer housing and its impact of development and transfer performance.

Title: Gray Balance Control Loop for Digital Color
Abstract: Four-color process printers generally use gray balance for achieving color balance. Here we describe a novel gray balance control system which uses multivariable state feedback principles. We show that the system performance is greatly improved and the requirements on number of color measurements per calibration initialization are greatly reduced. A synthesis of a state space control model, feedback controller and TRC smoothing techniques are discussed in detail to achieve good prints after gray balance. Experimental results are shown to validate the approach when used for real-time feedback control of color systems.
Speaker: Lalit K. Mestha
Title: Comparison of 1-D, 2-D and 3-D Printer Calibration Algorithms with Printer Drift
Abstract: For consistent color reproduction, a digital printer must operate in a stable mode. However, due to uncertainties such as changes in humidity and temperature, color printers drift over time. Calibration is an approach that can be used to bring back the printer to its initial state from a drifted state. Different algorithms are used to calibrate printers. Among them are one-dimensional gray balance1, one-dimensional channelwise linearization1, two-dimensional calibration1, and three-dimensional calibration2. In this paper, we benchmark the performance of different calibration algorithms in stabilization of digital color printers subject to printer drift. The figure of merit used for comparison is the improvement in CIELAB ∆E between the output of calibrated machine and the output of the machine in a drifted mode for the same input. We also examine the optimum number of color patches needed to be measured for calibrating the machine with different calibration algorithms. The optimum number of patches is selected using dynamic optimization algorithm3. Simulation results are presented using real printer data.

IMAP 2005 - 38th International Symposium on Microelectronics
September 25 - 30
, Philadelphia, PA
Authors: Joe Swift, Mike Butler, Stanley Wallace
Abstract: This paper describes research into carbon fiber, in forms of carbon fiber composites (CFCs) and carbon fiber tow, as a new material for electronic interconnects. Carbon fiber has been routinely used in structural applications in, for example air transportation, aerospace, and consumer applications. More recently they have found use in some limited electrical applications. In this study, we provide electrical properties data which suggests that carbon fiber-based interconnects can be applied across different packaging levels, such as package-to-board and board-to-board interconnections. Each interconnect member can consist of a large number of individual carbon fibers which can act cooperatively to provide a high degree of reliability and predictability to the interconnect function. These novel interconnects can join to conventional circuitry by pressure/physical contact, solder, or conductive adhesive. Multiple interconnect members can be integrated to provide multiple In/Output interconnections within a single assembly. To achieve enhanced conductivity and solderability, individual carbon fibers can be coated with a thin layer of metal, such as nickel. Thermal expansion and thermal stability characteristics are also presented in this report and used to support the proposition that carbon fiber-based composites are a candidate material for the next generation of electronic interconnects.

Abstract: This paper presents a phrase-based statistical machine translation method, based on non-contiguous phrase, i.e. phrases with gaps. A method for producing such phrases from a word aligned corpora is proposed. A statistical translation model is also presented that deals such phrases, as well as a training method based on the maximization of translation accuracy, as measured with the NIST evaluation metric. Translations are produced by means of a beam-search decoder. Experimental results are presented, that demonstrate how the proposed method allows to better generalize from the training data

Topic: Organic Light Emitting Devices: Technology Outlook and Current Challenges
Speaker: Hani Aziz
Abstract: The last 15 years have witnessed enormous interest, by academia and industry alike, in the emerging technology of Organic Light Emitting Devices (OLEDs). The reason for the interest is the promise that OLEDs will offer high light efficiency (several lumens/watt), high brightness (103-105 cd/m2), low driving voltage (< 10 V dc), fast response (~ Ýs), un-restricted viewing angle, and low cost. These attributes uniquely position OLEDs as potential replacement for existing display technologies that are currently dominated by liquid crystal displays. The last 3 years saw the first wave of commercial products, signaling the beginning of a new era for OLEDs.
Despite its arrival in the marketplace, the technology still faces significant challenges. One major hurdle is the relatively poor OLED stability, which results in limited device lifetime [1]. Although much less critical, higher device contrast and efficiency are still needed for some applications. In addition, reaping the potential cost advantage that OLEDs can provide requires developing simpler display RGB patterning techniques.
At Xerox, a primary focus of our OLED research has been to address some of these challenges. We have elucidated the degradation mechanism of devices based on widely used AlQ3 molecule [2]. The understanding of degradation mechanisms has provided important insights for designing long life OLEDs, and developing the industry¡¦s benchmark mixed-layer devices [3]. We also developed a light absorbing metal nano-particle electrode (Black CathodeTM) for enhancing display contrast [4,5]. More recently, we demonstrated low driving voltage (high efficiency) devices by utilizing novel high electron mobility triazine electron transport material.
In this seminar, I will give a general introduction to OLEDs, and a brief outlook on the technology. I will describe some of the existing challenges and highlight some of our contributions in this area.

Topic:Timing in the Art of integration: That s how the Bastille got stormed
Abstract: This paper uses a long term ethnographic study of the design and implementation of an electronic patient records (EPR) system in a UK hospital trust to consider issues arising in the multi-faceted process of integration when a customizable-off-the shelf (COTS) system is configured and deployed in a complex setting. The process involves trying to artfully work out how disparate technologies integrate with existing and evolving patterns of work within developing regulatory requirements. We conclude by suggesting ways in which ethnographic interventions and user involvement may be timed and targeted to aid in achieving this process.

Topic: Situating Ubiquitous computing in everyday life: bridging the social and technical divide
Abstract: Despite the appeal of Weiser's vision for the computer in the 21st century there is, at this current moment in time, a great divide between technical developments and their resonance with the everyday settings in which they might be deployed. We believe that working out the significance of the social is a central problematic for ubiquitous computing if the divide is to be bridged. However, weaving technical developments into everyday settings ultimately depends on working out what the 'social' consists of and what it means for Ubicomp. As a first measure in what has to be a long-term consideration of these issues we invite participation from interdisciplinary researchers who have experience in the field. The goal of this workshop is to enable themes of generic purchase to the developers of UbiComp systems to be initially identified and articulated.

Speakers: Brinda Dalal,Palo Alto Research Center, Inc. & Patricia Wall, Xerox Corporation
Abstract:This paper explores whether or not Marcel Mauss's concept of the gift is applicable to understanding the diverse roles that ethnographers assume in corporate environments. Kneading together the themes of gift exchange from anthropological literature on the one hand and "Representations" from the participatory design research community on the other; we suggest that the artifacts we create and share with customers actually evoke the presence of the gift in customer interactions. We argue that specific types of representations - a key component in our methodological toolkit - may be likened to the thirteenth loaf in the baker's dozen; given to the customer to demonstrate equitable partnerships, enhance communication and garner trust in a perpetually changing marketplace. Using case studies, we examine how these objects illuminate the complexity of our own sociality in professional settings and furthermore, help to deepen or transform customer service engagements.

International Conference on Data Mining - ICDM '05
November 27 - December 1
, New orleans, LA
Speaker: Nathaniel Martin
Topic: TextSieve: Text mining by Subject Matter Experts
Abstract: Categorization algorithms typically create a model by generalizing from a training set. The training set comprises documents that a subject matter expert has already categorized. Unfortunately, building such a set can be tedious and error prone.
We describe a program, called TextSieve, which helps a subject matter expert construct a training set that is more internally consistent. It can also serve as a tool for ad-hoc text mining by subject matter experts. Unlike machine learning categorization, it works better on short documents than on long documents providing a complementary capability to machine learning based text mining.

Topic:Co-occurrence models in music genre classification
Abstract: Music genre classification has been investigated using many different methods, but most of them build on probabilistic models of feature vectors xr which only represent the short time segment with index r of the song. Here, three different co-occurrence models are proposed which instead consider the whole song as an integrated part of the probabilistic model. This was achieved by considering a song as a set of independent co-occurrences (s; xr) (s is the song index) instead of just a set of independent (xr) s. The models were tested against two baseline classification methods on a difficult 11 genre data set with a variety of modern music. The basis was a so-called AR feature representation of the music. Besides the benefit of having proper probabilistic models of the whole song, the lowest classification test errors were found using one of the proposed models.

Topic: Tailoring the Functional Properties of Fluoroelastomers: Novel Curing Systems
Abstract: This presentation will describe the work process followed by Xerox to develop new materials and enabling surfaces that provide improved fusing performance in electrophotographic marking engines. The needs for high-quality color images, high print speeds, long-life components, low run costs, wide substrate latitude, and environmental friendliness demand continuing improvement of all electrophotographic marking subsystems, especially fusing.
The first portion of the paper will describe the work process required to develop enabling components for marking subsystems, beginning with the identification of new subsystem requirements. These requirements are translated into proposed new material properties. New materials are then designed and tested, and prototype components are fabricated and fixture/machine tested. The process is iterated until the required performance is achieved. The major emphasis of this paper is the work content surrounding the final step: optimizing performance.
The second portion of the paper will describe specific examples of fuser materials design, concentrating on fluoroelastomers. Due to their known chemical and thermal stability, fluoroelastomers are especially useful for fuser applications for high speed B&W and color printing with both dry toner and liquid or phase change inks. There are still, however, several major challenges that the marking industry is facing relative to life of the surfaces and their ability to provide adequate and sustained release over millions of print impressions. The primary causes for premature failures are the harsh nip environments including high pressure and steam, repeated contact with abrasive media, and chemical reactions with toner and ink components. While there are several approaches to addressing these issues, the focus of this paper will be on the approach to improve material compositions and functionality through the modification of cure system technology. We will describe a comparative study of standard curing methodologies against novel cure systems based on functional silanes, functional hydrocarbons, and hybrids thereof. We will also review test data demonstrating improved composition performance with these novel curing systems.
