Electronic Imaging 2006 Symposium
January 15 - 20
, San Jose, CA
Topic: Expression of Document Structure in Automatic Layout
Speakers: Steven J. Harrington, Rhys Price Jones, J. Fernando Naveda, Nishant Thakkar (Xerox Corp. Webster, NY 14580) (George Washington Univ., Washington, DC 20052) (Rochester Institute of Technology, Rochester, NY 14623) (IBM Corp. Rochester, MN 55901)
Abstract: With the dynamic generation of documents and their presentation on various output devices, it is valuable to automatically adjust their layout and style. Measures for layout desirability have typically focused on document aesthetics (making the document look good). But other values are also important. This paper explores measures for the effectiveness with which style and layout convey the document's logical structure. This primarily contributes to the document's ease of use. The measures described are the group identity, separability and distinguishablity of elements. These measures are defined as combinations of simpler, properties that are practical to calculate.

Seminar - University of Montreal
February 6
, Montreal, QC
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 (~ ?s), 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.

7th International Association for Pattern Recognition Workshop on Document Analysis Systems
February 13 - 16
, New Zealand
"System for converting PDF documents into structured XML format", HervŽ DŽjean, Jean-Luc Meunier.
In this paper we present a system to convert PDF legacy documents into structured XML format. This conversion system first extracts the different streams contained in PDF files (text, bitmap and vectorial images) and then applies different components in order to logically structure them. Some are traditional in document analysis, others more specific to PDF. We also present a graphical user interface in order to check, correct and validate the analysis of the components. The final XML schema corresponds with a generic representation of documents. After having presented the different components and the general architecture, we eventually report on real user cases.

March 20 - 23
, Corning, NY
Speaker: Greg Kovacs
Topic: Lean Six Sigma and New Focus on DfLSS in Xerox Innovation Group (R&T)
Abstract: As part of the larger Xerox program, Xerox R&T embarked on a Lean Six Sigma initiative in 2003 and successfully met its financial targets in 2004 and 2005, the first two full years of the program. During 2005 Xerox next initiated a Design for Lean Six Sigma (DfLSS) program, which in many ways offered a closer connection to the R&T mission, focused at the front end of the new product development pipeline. This presentation will describe the strategies adopted by Xerox R&T in responding to the challenges of (1) deploying Lean Six Sigma in research, and (2) growing a culture around the DfLSS goals of developing highly competitive new products and "getting it right" the first time vs. the Lean Six Sigma goals of improving existing products and processes. The approaches to training and certification will be discussed along with the successes and challenges being faced in implementing the strategy. Finally the path forward for growing and capitalizing on the DfLSS initiative will be described.

European Conference on Information Retrieval
April 10 - 13
, London, UK
Topic: Lexical entailment for information retrieval
StŽphane Clinchant, Cyril Goutte, Eric Gaussier.
Textual entailment has recently been proposed as an application independent task of recognising whether the meaning of one text may be inferred from another. This is potentially a key task in many NLP applications. In this contribution, we investigate the use of various lexical entailment models in Information Retrieval, using the language modelling framework. We show that lexical entailment potentially provides a significant boost in performance, similar to pseudo-relevance feedback, but at a lower computational cost. In addition, we show that the performance is relatively stable with respect to the corpus the lexical entailment measure is estimated on.

Challenges in Document Management and Imaging Technologies
April 17
, Georgia Tech
Speaker: Siddhartha Dalal, Vice President, Imaging and Services Technology Center, Xerox Corporation
Abstract: In the late 80s Xerox researchers started an ambitious project on Ubiquitous Computing. Assuming availability of the computing infrastructure; it defined a paradigm for interaction inspired by constant access to information and services. Specifically it dealt with three themes, namely, natural interfaces, context aware applications and automated access. Through the incredible advances by researchers around the world over the past 15 years, several of the seminal ideas from Xerox's vision are already part of our everyday life. As we move in 21st century, we explore whether a new similar paradigm is occurring in imaging and document management through the fabric provided by Ubiquitous Computing. As a part of it, we will highlight recent work in Imaging and Document Management spaces by Xerox researchers.

Abstract
The use of rapid control prototyping tools has greatly increased the productivity of Researchers at Xerox Corporation. Currently, research efforts yield critical parameters, proof of feasibility and algorithms as applied to print technology. These artifacts are handed off to production design teams for product development. Xerox is striving to extend the benefits of rapid control prototyping beyond research, and into the product development workflow. Collaboration between Xerox, Freescale and dSPACE has been established to provide the missing links in the tool chain from simulation models to deployment of control solutions on product intent hardware.

ICIS 2006: International Congress of Imaging Science
May 7 - 13
, Rochester, NY
Speaker: Karen Braun
Topic: Memory Color Enhancement Algorithm
Abstract: We introduce an algorithm that squeezes colors toward preferred point in color space. This preferred point could be the optimal skin, sky, grass, or spot color, or any other important color. No segmentation of the image is used to isolate the colors of interest, which has two advantages: first, no contours are introduced in the transitions between adjusted and unadjusted colors, and second, the algorithm can be implemented as a look-up table, fitting nicely into the ICC paradigm. Psychophysical testing showed the algorithm gave equal or improved rendition over the unadjusted originals.
Speaker: Raja Bala
Topic: What to lose sleep over in digital color imaging
Abstract: Much of today's color imaging is based on a trichromatic pixelwise representation of color. Yet a realistic color imaging experience involves consideration of additional dimensions such as spectral, spatial, and goniometric effects. This paper presents challenges encountered in incorporating these higher dimensions into mainstream color imaging. We discuss important factors to be considered as these challenges are addressed. These include trends in color technologies, research in human color perception, intelligent interfaces, the importance of a systems approach, and the synergies acquired from cross-disciplinary interactions.
Speaker: Eric Hamby (add'l authors: Y. Eun; P. Ramesh)
Topic: Control Oriented Modeling of a Hybrid Two-Component Development Process for Xerography
Abstract: This paper presents a methodology for developing a control oriented model for a hybrid development architecture. The resulting model is suited for multivariable controller design and analysis to stabilize and improve the development process. The proposed methodology extracts relevant characteristics from an experimentally validated complex model based on toner age distribution and development probability. Three lumped state variables are proposed to characterize the macroscopic properties of the process. Ordinary differential equations of the proposed states are then derived to characterize the system dynamics of the process. Simulation results show that, for the properties of interest, the control oriented model yields similar results as the complex model for a wide range of operating conditions. Although the results presented are for a development process, the methodology can also be extended to other xerographic processes.

Topic: An Automated Defect Classifying Process for Printed Document
Abstract: A method for automatic identification of image quality defects on printed documents is described. The method first detects and removes any possible halftone screens existing on the scanned image of interest. A Gaussian smoothing is then applied to reduce the noise variations. This is followed by global thresholding to define a specific region-of-interest (ROI). A further localized thresholding within the ROI, using a variant of Otsu's method, is employed to clearly isolate the objects. The objects are then made scale, rotation and translation invariant using Principal Components Analysis (PCA) normalization procedures. An elliptical fit is then applied to the object's contour and tested using Hausdorff distance measures. Finally, features based on the object size and elliptical distances are extracted from the region internal to the derived ellipse for classification. Our proposed algorithm was tested on over 700 images yielding 83.4% classification accuracy.
Speaker: Wencheng Wu
Topic: A New Algorithm for Streak Detection in Mottle and Noisy Images
Abstract: This paper describes an algorithm for detecting streaks in printed images using adaptive window-based image projections and maximization of mutual information. To this effect, the images are first de-skewed to minimize the need to calculate projections across all angles. Then, projections are computed across the entire image at different windows sizes. The traces collected from the projections are correlated using maximization of mutual information to pinpoint streak locations using a peak detection algorithm. Finally, for a given peak, the window size is changed adaptively to identify and locate the intensity, width, and length of the corresponding streak, while maximizing signal to noise ratio. Results on synthetic and real-life images will be provided to demonstrate the effectiveness of our proposed technique.
Speaker: John Handley
Topic: Scanned Color Document Image Segmentation Using the EM Algorithm
Abstract: A robust, efficient scanned color document segmentation algorithm is presented that performs a three-dimensional (3D) thresholding of color pixels. At the heart of the algorithm is the Expectation-Maximization (EM) algorithm which fits a mixture of two 3D gaussians to L* a* b* color data sampled from pixels in the image to separate foreground image content from background. The thresholding process uses a quadratic boundary to produce a selector plane that indicates, for each pixel, whether it belongs to foreground or background. The binary selector plane is further processed and analyzed to extract objects such as photographs or graphics. Segmented document images are then encoded in a mixed raster content format for efficient compression.

9th European Conference on Computer Vision
May 7 - 14
, Graz, Austria
"Adapted vocabularies for generic visual categorization", Florent Perronnin, Chris Dance, Gabriela Csurka, Marco Bressan.
Many state of the art Generic visual categorization (GVC) systems are built around a vocabulary of visual terms and characterize images with one histogram of visual word counts. We propose a novel approach to GVC based on a universal vocabulary, which describes the content of all the considered classes of images, and class vocabularies obtained through the adaptation of the universal vocabulary using class-specific data. An image is characterized by a set of histograms - one per class - where each histogram describes whether the image content is best modeled by the universal vocabulary or the corresponding class vocabulary. It is found experimentally that this novel representation greatly improves the performance compared to an approach based on a single vocabulary at the cost of a modest increase in the computation.

IEEE International Conference on Acoustics, Speech, and Signal Processing
May 14 - 20
, Toulouse, France
Topic: Dynamic Optimization Algorithm for Generating Inverse Printer Map with Reduced Measurements
Speakers: Sohail Dianat*, LK Mestha#, Athimoottil Mathew*
*Rochester Institute of Technology Rochester NY 14623, #Xerox Corporation, Webster, NY 14580
Abstract:For a color printer to attain good color rendering quality the image output terminal must be capable of producing the desired tone, i.e., the solidness, of each of primary color separations as requested. Calibration is a major task in providing high quality prints. A model (characterization) of the color printer is a first step for building profiles. Most of the methods used to solve the calibration problem utilize, in one way or another, a printer inverse map. Once the inverse map is constructed, the input image will be processed by the inverse map to obtain the correct CMY values that can produce the desired Lab values. A major drawback in this type of calibration is the need to measure color patches each time we need to calibrate the printer. We propose an alternative approach, where few critical color patches are measured and the rest of the points in the forward printer map are obtained using interpolation.

Topic: Session 17: Digital Color Management: Putting Standards to Use
Abstract: Automated color management dates back to the early 1990s. Over time, workflow has become critical to this market's success and future. Print On Demand requires zero waste and quick turnaround times, and necessitates a robust color management solution. Vendors have addressed the requirement for high-speed color managed print jobs in a number of ways, from device calibration and profiling to finding the right compromise between speed and color fidelity. Future digital print technologies will eventually eclipse the current crop of products in terms of throughput, and it is clear that color management will be one of the building blocks of high-speed Print On Demand workflow.

3rd IEEE International Conference on Autonomic Computing

, Dublin, Ireland
Speaker: Naveen Sharma
Topic: Collaborative Self-Organization by Devices Providing Document Services - A Multi-Agent Perspective
Abstract: In a service oriented environment such as the realm of document services, the conventional notion is that of a multifunction device interacting individually with customer applications and the service-provider's offerings. Counter to this view, the key emerging idea is that of a network of Multi-Function Devices1 (MFD) providing service as a collaborative system. While the consumer of service could benefit from high availability, caching and data reuse, redundancy and higher performance, the service provider also benefits from being able to define additional service over the collection of devices. By assuming a multi-agent perspective of this service-oriented environment, we propose a autonomic mechanism through which the collection of devices can self organize. The self-organization is carried out in two steps firstly, the devices assemble themselves in to a meaningful structure and subsequently configure themselves by assuming suitable roles in the distributed multi-agent system. By doing so the multi-agent system comprising of the devices exhibit better immunity to information load and failure, consequently becoming a survivable service oriented architecture. We propose a few algorithms to do this and validate them using simulations

Topic Enabling Self Managing Applications using Model-based Online Control Strategies
Xerox Speaker: Hua Liu
Abstract: The increasing heterogeneity, dynamism and uncertainty of emerging DCE systems imply that an application must be able to detect and adapt to changes in its state, its requirements, and the state of the system to meet its desired QoS constraints. As system and application scales increase, ad hoc heuristic-bsed approaches to application adaptation and self-management quickly become insufficient. This paper builds on the Accord programming system for rule-based self-management, and extends it with model-based control and optimization strategies. This paper also presents the development of self-managing data streaming services based on online control using Accord. These services are part of a Grid-based fusion simulation workflow consisting of long-running simulations, executinig on remote supercomputing sites and generating several terabytes of data, wich must then be streamed ovr a wide-area network for live analysis and visualization. The self-managing data streaming services minimize data streamiing overheads on the simulations, adapt to dynamic network bandwidth, and prevent data loss. An evaluation of the services is also present

International Conference on Machine Learning, (ICML)
June 25 - 29
, Pittsburgh, Pennsylvania
Topic: Categorisation in multiple category systems. Speakers:
Gabriela Csurka, Eric Gaussier, Cyril Goutte, Francois Pacull, Jean-Michel Renders, XRCE. Abstract: We explore the situation in which documents have to be categorised into more than one category system, a situation we refer to as multiple-view categorisation. Such a situation arises for example in large companies where incoming mails
have to be routed to several departments, each one relying on its own category system. We focus here on exploiting possible dependencies between category systems in order to refine the categorisation decisions made by categorisers trained independently on different category systems. After a description of the multiple categorisation problem, we present several possible solutions, based either on a categorisation or reweighting approach, and compare them on real data. Lastly, we show how the multi-media categorisation problem can be cast as a multiple categorisation problem and assess our methods in this framework.

Topic: Documentum ECI Web Wrappers: Performance analysi. Speakers: Boris Chidlovskii, Bruno Roustant, Marc Brette. Abstract: Documentum Enterprise Content Integration (ECI) services is a content integration middleware that provides one-query access to the Intranet and Internet content resources. The ECI Adapter technology offers an interface to any application for data and metadata extraction from unstructured Web pages. It offers a unique framework of wrapper production, automatic recovery and maintenance, developed at Xerox Research Center Europe and based on state-of-art algorithms from machine learning and grammatical inference. In this presentation we analyze the performance of ECI adapters deployed in current commercial installations. We benefit from accessing reports on daily tests for all ECI commercially deployed adapters collected from June 2003 to September 2005. Using the daily reports, we analyze different aspects of the wrapper technology.

XRCE open house seminar: Bag-of-features and beyond
June 29
, Everest
Cordelia Schmid senior scientist
at Inria Rhone-Alpes, France, presents: Bag-of-features and beyond
The first part of this talk presents a large-scale evaluation of an approach
that represents images as distributions (signatures or histograms) of features
extracted from a sparse set of keypoint locations and learns a Support Vector
Machine classifier with kernels based on two effective measures for comparing
distributions, the Earth Mover's Distance and the X2 distance. Experimental
results obtained with this bag-of-features representation are surprisingly good
despite the lack of spatial information.The second part illustrates two ways
of incorporating spatial information. The first one is based on the approximate
global geometric correspondence. It works by partitioning the image into increasingly
fine sub-regions and computing histograms of local features found inside each
sub-region. The resulting "spatial pyramid" is a simple and computationally
efficient extension of an orderless bag-of-features image representation, and
it shows significantly improved performance on challenging scene categorization
tasks. The second extension is a technique for category classification which
exploits spatial relations between features by using the object boundaries within
the training images. It boosts the weights of features that agree on the position
and shape of the object and suppress the weights of background features, hence
the name of our method --- "spatial weighting". The proposed representation
is thus richer and more robust to background clutter. Experimental results show
that our approach improves the results of one of the best current image classification
techniques. Furthermore, we apply the spatial model to object localization.
Initial results are promising.
This is joint work with S. Lazebnik, M. Marszalek, J. Zhang and J. Ponce.

IIIA - International Workshop on Intelligent Information Access
July 6 - 9
, Helsinki, Finland
Speaker: Nicola Cancedda, XRCE
Topic: SMART: Research Directions
Abstract: More than half of the EU citizens are not able to hold a conversation in a language other than their mother tongue, let alone to conduct a negotiation, or interpret a law. In a time of wide availability of communication technologies, language barriers are a serious bottleneck to European integration and to economic and cultural exchanges in general. More effective tools to overcome such barriers, in the form of software for machine translation and other cross-lingual textual information access tasks, are in strong demand. Statistical methods are a promising approach, in that they achieve performances equivalent or superior to those of rule-based systems, at a fraction of the development effort. There are, however, some identified shortcomings in these methods, preventing their broad diffusion. SMART is an attempt to address these shortcomings by deploying the methods of modern Statistical Learning. The scientific focus is on developing new and more effective statistical approaches while ensuring that existing know-how is duly taken into account. Field evaluation on three user scenarios will ensure that advances make their way out of the laboratories, in the form of both improvements over existing technologies and of new applications.

Topic: Active, Semi-Supervised Learning for Textual Information Access
Abstract: Machine learning techniques have been used for various tasks of document management and textual information access, such as categorisation, information extraction, or automatic organization of large document collections. Acquiring the annotated data necessary to apply supervised learning techniques is a major challenge for text applications, especially in very large collections. Annotating textual data usually requires humans who can read and understand the texts, and is therefore very costly, especially in technical domains. In this contribution, we address the problem or reducing this annotation burden.

ISA (International Sociology Association) Conference
July 23 - 30
, Durban, South Africa
Topic: Mundane technical reasoning and systems design. Speaker: Jacki O'Neill, XRCE.
Abstract: This paper provides an analysis of members mundane reasoning about technology, in particular how that reasoning comes into play when that technology breaks down. The primary source of data is telephone service encounters between customers and trouble-shooters about broken office devices, with additional data from customers interactions with an online support system. Trouble-shooters linguistic practices for working with customers mundane reasoning about the machine are described. Trouble-shooters transform customers descriptions into the technical understandings of machine problems necessary to arrive at some solution. Trouble-shooters and customers deal with symptoms and causes to arrive at a common understanding of the machines faults and their solutions, with trouble-shooters making their hearably good advice appropriate to this situation. However, common understandings are not always successfully reached and issues of evidence and how reality disjunctures (Pollner, 1975) are handled are examined.
The paper has implications for the design of both the technology itself and online support systems, such as knowledge bases, intended to substitute for trouble-shooter interactions. It demonstrates the need to take into account customers reasoning and linguistic practices in the design of support systems. At the most basic level systems should enable customers to uncover the problem using vernacular, symptomatic problem descriptions, rather than requiring highly specific technical vocabulary. However, this paper demonstrates how this alone is not enough for successful troubleshooting. Even where customers have the means to arrive at the correct solution for the problem, they may disregard the solution. System design should treat the user as a reasoning being rather than simply an input-output device, taking into account mundane reasoning practices and enabling customers to identify where there is a mismatch between their mundane reasoning about the artefact and the technical reasoning which could result in artefact repair.
The paper offers suggestions for how online systems might best utilise customers linguistic and reasoning practices to enable the customer and the service organisation to get the greatest benefit out of such support offerings.

July 31 - August 10
, University of Malaga, Spain
Aaron Kaplan presents a paper: Simulative inference in a Computational model of belief
"When a person learns something new, he generally draws some conclusions from it, but he will miss or ignore some logically valid conclusions ( people are not logically omniscient), and furthermore he may draw conclusions that do not logically follow from the new information (people s beliefs are not derived purely by deduction). Therefore, in order to reason accurately about what someone believes, it is necessary to know something about how he thinks. We propose a family of logics in which belief is modelled as the result of applying an algorithm to a set of input sentences. We define inference rules that can be used to reason about what someone believes by simulating the application of his belief algorithm, and we explore conditions under which these inference rules are sound and complete."

ICPR (International Conference on Pattern Recognition)
August 20 - 24
, Hong Kong, China
Speaker: Jutta Willamowski, XRCE
Topic: Probabilistic automatic red eye detection and correction. Abstract: In this paper we propose a new probabilistic approach to red eye detection and correction. It is based on stepwise refinement of a pixel-wise red eye probability map. Red eye detection starts with a fast non red eye region rejection step. A classification step then adjusts the probabilities attributed to the detected red eye candidates. The correction step finally applies a soft red eye correction based on the resulting probability map. The proposed approach is fast and allows achieving an excellent correction of strong red eyes while producing a still significant correction of weaker red eyes. Authors: Jutta Willamowski, Gabriela Csurka.

Speaker, Tamas Gaal
Topic: Multitape automata with symbol classes.
Abstract: We propose a new model of finite state machine: multi-tape automata with symbol classes and identity and non-identity constraints (in short MASCIN). This model generalizes both classical single or multi-tape machines, and machines with extended alphabet. We define this model in terms of a constraint satisfaction problem and discuss a problem occurring when projection is used on the model. Finally, we describe its implementation and results of a performance test.

XRCE open house seminar: A Semantic Annotation Environment to Support Sense-Making
September 7
, Everest
Seminar given by: Bertrand Sereno, Knowledge Media Institute, Open University, Milton Keynes, U.K: PhD student.
Prototype Internet infrastructures for scholarly publishing offer powerful new services over interconnected ideas and arguments in scientific literature. However, such services depend on documents being semantically annotated with readers' interpretations, which up until now has been a manual process due to the complexity of such analysis. We investigate the challenge of designing computer-support for document annotation of potentially diverse, contested views concerning the relevance of texts in scholarly publications.
An interaction design approach has been adopted to progressively (i) understand the dialogue between the end-users and an appropriate annotation environment, (ii) develop such an environment and (iii) evaluate its usability. The evaluation focuses on how the semantic annotation scheme is used by novices and experts, and on how the interaction is shaped by the user interface that provides annotations provided by the system as well as by the end-users. Finally, we assess critically the strengths and weaknesses of the work.

Topic: Was Micro-Capsules prepared through emulsion aggregation and coalescence
Abstract: Introduction
Core/shell structured materials can be prepared through numerous approaches, of which encapsulation technique has been intensively explored. The core is usually composed of active agents, while the shell is a protective layer. The construction of the shell has become an art for material scientists. In general, the shell could be constructed through chemical reactions and / or through physical packaging. Emulsion polymerization including micro-emulsion polymerization and mini-emulsion polymerization, suspension polymerization and dispersion polymerization are good examples of reactive construction for the shell [1-4]. When reactive functional groups on the core surface become available, interfacial polycondensation could be used in building the shell [5-7]. Layer-by-layer (LBL) assembly method combined with Langmuir-Blodgett technique is a versatile approach for the shell construction [8, 9]. LBL method utilizes electrostatic interactions between oppositely charged polyelectrolytes to create the multilayered shell of alternating positive and negative charges with nanometer scale sub-layer thickness. The thickness of the shell is one of the critical factors that control the release of active core materials [10].
Self-assembly is a simple and robust approach to spontaneously create shells with desired properties that encapsulate active agents. Layer-by-layer assembly of charged polymers and particles onto charged templates of colloidal particles has enabled the controlled formation of composite structure [11]. Colloidal particles with charges on the surfaces are attractive materials for building capsules because particles with vast array of material properties are readily available. Moreover, many of these surface properties are readily modified, facilitating assembly onto an array of chemically district surface. For these same reasons, colloidal particles are also suitable as components of assembled shells.
Wax is one of the important components in digital imaging materials such as ink, toner and paper. To achieve better image quality, the function of wax must be controllable in image process, because most waxes have poor compatibility with other organic / inorganic materials. In this paper, we discuss the preparation of wax micro-capsules through emulsion aggregation and coalescence.

September 10 - 14
, Philadelphia, PENN
Speakers: Eun Suk Suh, Xerox Innovation Group; Olivier L. de Weck, Center for Innovation in Product Developnent, MIT
Topic: Flexible Product Platforms: Framework and Case Study
Abstract: Customization and market uncertainty require increased functional and physical bandwidth ini product platforms. This paper presents a platform design process in response to such future uncertainty. The process consists of seven iterative steps and is applied to an automotive body-in-white (BIM) where 10 out of 21 components are identified as potential candidates for embedding flexibility. The paper shows how to systematically pinpoint and value flexible elements in platforms. This allows increased product family profit despite uncertain variant demand, and specification changes. We show how embedding flexibility suppresses change propagation and lowers switch costs, despite an increase of 34% in initial investment for equipment and tooling. Monte Carlo simulation results of 12 future scenarios reveal that as the degree of uncertainty increases, the value of embedding flexibility also increases.

4th IFAC Symposium on Mechatronic Systems
September 12 - 15
, Heidelberg, Germany
Authors: M. Krucinski, R. Sanchez, E. Ergueta, R. Horowitz, M. Tomizuka, B. Fine
Topic: A Mechatronic Approach to Full Sheet C ontrol Using Steerable Nips
Abstract: State of the art high speed color printers require
sheets be accurately positioned as they arrive at the image
transfer station. To accomplish this goal, a steerable nips
mechanism has been designed and built. This mechanism is
located at the end of a printer's paper path upstream from the
image transfer station. This steerable nips mechanism allows
sheets to be precisely controlled in the longitudinal, lateral,
and skew directions. In this paper we present the design,
sensing strategy, and a control law based on state feedback
linearization. The proposed controller is able to move the sheet from an initial to a final state under the condition that the sheet has nonzero initial and final velocities. The system model is nonlinear and subject to four nonholonomic constraints. Two of these constraints are related to the fact that the velocities perpendicular to the wheels must be zero, and the other two constraints are due to the non-slip condition.

Topic: Understanding the Influence of Surface Acid and Base Properties and Water on Work Functions and Triboelectric Charging Using Inverse Gas Chromatography
Abstract: Inverse Gas Chromatography (IGC) has been applied to study surface acid, base and dispersion properties of xerographic developer materials. Model carrier and toners were prepared, blending the toners with nano-particulate metal oxide surface additives: silica, titania and alumina. The effect of varying additives on charging, work functions and surface chemistry measured by IGC was studied. Extending previous work, all properties were also evaluated as a function of relative humidity, to improve understanding of the role of water. Under both dry and wet conditions, results support a work function model for charging, where material work functions are determined by surface acid-base properties. At high humidity, IGC follows the changes in surface chemistry due to water adsorption, which in turn relate to changes in work functions and triboelectric charging.

Topic: Some Fundamental Performance Aspects of the iGen3 Development System
Abstract: The Xerox iGen3 is a digital color production press introduced in 2002. It assembles the four CMYK color separations on the photoconductor prior to a single transfer to substrate in a process known as Image-on-Image (IOI). Central to IOI in iGen3 is a development system capable of high speed and quality without degrading previously developed images. iGen3 accomplishes this with a gapped powder-cloud development system known as Hybrid Scavengeless Development (HSD). HSD differs in many ways from typical two-component magnetic brush development systems. This paper describes the iGen3 HSD system and discusses some of its fundamental performance characteristics, concentrating on the relationship between developability and parameters that affect electric fields and toner supply.

NIP22 and Digital Fabrication 2006
September 17 - 22
, Denver, Colorado
Topic: High Image Quality achieved through High Precision Measurements
Speaker: Howard Mizes
Abstract: The high image quality of recent xerographic and direct marking products are achieved in part by accurately placing marks on the paper to microns precision at substrate speeds of up to 500 mm/sec. Accurate measurement techniques are required to develop products with this capability. Measurements of the positions of marks on paper to sub-micron precision can be achieved by printing and scanning specific test patterns. Even though scanner resolutions are tens of microns, the measurement precision is increased orders of magnitude by using various signal processing techniques and massive statistical averaging on the hundreds of megabytes of information. Examples include (1) measurement and adjustment of an LED bar imager to achieve uniform images, (2) measurement and adjustment of beam positions to compensate for imperfections in a motor polygon assembly, and (3) signal processing techniques to compensate for imperfections in contact image sensors.

Topic: Control Analysis of a Hybrid Two-Component Development Process
Speaker: Yongsoon Eun
Abstract: In this paper, we will illustrate the utility of a control oriented model for a hybrid two component development process. The model used for control extracts relevant characteristics from an experimentally validated numerical model based on toner age distribution and development probability. Equilibrium analysis of the model shows that developability loss associated with low area coverage, low humidity operating conditions can be attributed to the fact that the development process is not operating around an equilibrium point. Velocity field analysis indicates the process has limited controllability under these operating conditions. Based on these observations, a constrained optimal control problem is formulated to develop a control strategy to maximize the operating time while maintaining acceptable developability. The numerical solution shows that for a given operating condition, with bounded toner concentration and development voltage, the optimal dispense strategy is a concatenation of a zero-dispense profile and a controlled dispense rate associated with operating the development voltage at its maximum value.

Topic: Hierarchical Dependence Graphs for Dynamic JDF Workflows
Abstract: The Hierarchical Dependence Graph (HDG) described in this paper extends the theory of directed acyclic graph (DAG) [1,2] by allowing hierarchical representation of workflows. It can be used to explicitly express the dependences across JDF [3] (process) nodes and resources derived from any JDF job description. It defines a flexible and semantic-rich model to represent JDF workflow as a set of DAGs at different abstractions: intent level, process group levels and process execution level. By explicitly representing JDF workflows in the HDG, not only it enables the separation of the workflow itself from MIS/or Controller implementations to support fully dynamic JDF workflows, but also it provides a theoretic basis for formal analysis of JDF workflows. Furthermore, we introduce the concept of Connectivity Matrix and its transformations to allow two views derived from a single model: process-centric view and resource-centric view. By exploiting the fact that each of these views is a DAG with a hierarchical structure, we then show how various analytical properties defined for DAG can be recursively applied to analyze JDF workflows, particularly in the following perspectives: (1) validating JDF workflows in terms of cyclic dependence, missing resources and dangling resources; (2) identifying the impacted JDF nodes or resources due to the resource availability and workflow status changes; (3) intelligently handling failures or exceptions by considering causal relations between resources and processes.

Topic: An Intelligent Wizard for Automatic Workflow Modeling
Abstract:Workflow modeling is playing an increasingly important role in representing end-to-end business process for workflow analysis, integration, automation and optimization purposes. This paper introduces an intelligent tool that automatically generates workflow models based on a set of given user constraints and underlying service capability ontology for production printing domain through an ease-to-use wizard-like interface. Unlike any existing workflow modeling tool, this intelligent wizard does not require the users with technical expertise in process modeling. The wizard-like interface provided in the proposed tool enables business people to easily create workflow models that match the user constraints provided via a set of questionnaire. This paper discusses the tool's architecture and key components, such as domain ontology on user constraints and service capability, and ontology-based inference engine that implements the automatic workflow generation algorithm.

Topic: A Printing Workflow Recommendation Tool - Exploiting Correlations between Highly Sparse Case Logs
Speaker: Tong Sun, Xerox/ Ming Zhong, university of Rochester
Abstract: As a user preference prediction mechanism, recommendation techniques have been widely used to support personalized information filtering in current e-commerce applications. We build a recommendation tool into the existing Xerox printing workflow configuration system in order to provide new users with a number of solutions that are possibly of their interests. Such solution recommendations can significantly improve the system efficiency and accuracy by reducing workflow generation overhead and helping users quickly identify their needs.
In our work, the main challenge is the high sparsity inherent
to our application data ? most fields have missing values due to a customer's laziness, lack of background or uncertainty on their specific needs. We address this problem by using Latent Semantic Indexing (LSI) to merge original sparse data records into dense, semantic records. The generated dense data are then grouped into clusters based on their correlations. These clusters, together with their user patterns and representative workflows, are used to support efficient online workflow recommendation. Our implemented tool is able to achieve 83% accuracy on a dataset of 4569 case logs with 91% average sparseness.
