SQRL Report No. 28
Title: Guassian Elimination: a case study in efficient genericity
with MetaOCaml
Author: Jacques Carette
Abstract: The Gaussian Elimination algorithm is in fact an
algorithm family - common implementations contain at least 6 (mostly
independent) "design choices". A generic implementation can easily
be parametrized by all these design choices, but this usually leads
to slow and bloated code. Using MetaOCaml's staging facilities, we
show how we can produce a natural and type-safe implementation of
Gaussian Elimination which exposes its design choices at code-
generation time, so that these choices can effectively be
specialized away, and where the resulting code is quite efficient.
SQRL Report No. 31
Title: COG-PETS: Code Generation for Parameter Estimation in Time
Series
Authors: Christopher Kumar Anand, Jacques Carette, Andrew Thomas
Curtis, David Miller
Abstract: We extend previous work on symbolic code generation for
efficient solvers in the domain of image and signal processing, to
take advantage of recurrence relations for efficiently generating
model function values corresponding to a regularly-sampled time
series. First- and zeroth-order recurrences are symbolically
identified by Maple. Two example applications to Magnetic Resonance
Spectroscopy and Relaxometry are described, and we show two orders
of magintude accelerations for the resulting solvers.

Software Testers Invited: Job Survey
Do we know what we do and do not like in our daily job? Martins
Gills from Riga Information Technology Institute is conducting a
survey among software testers. The goal is to add some sketches to
the portrait of software tester. Some say the testers are special
persons, but testing itself is actually a quite boring activity. It
may depend on the tasks we do. The survey looks for things we prefer
or would like to avoid.
If you have 5-10 spare minutes for putting multiple-choice answers
to a bunch of questions, please visit the link:
http://support.dati.lv/tsurvey/index2_en.html
There is no registration and no ads. It will be active till the end
of July 2005.
Summary of the results will appear in QTN later this year.

Transactions on Systems, Man and Cybernetics Part A:
Special Issue on Collaboration Support Systems
http://www.agentgroup.unimo.it/tsmc06/
Collaboration is a widely applied style to collect a group of
people's intelligence. Collaboration support systems serve as an
important memory for the group. Ideally, such a system should evolve
to become a knowledge base for the collaborators and for those who
will use the results of the collaboration. How does one provide
effective software structures and tools that will support a large
group of people in their work, i.e., assembling, making use of,
extracting and working with extensive collections of ideas and
multi-media information? This question is still to be solved.
The aim of this special issue is to make the point of the situation
and to evaluate the state of the art in the field. Possible
submissions should relate to both innovative proposals and global
views of well-established systems/approaches not published
elsewhere. Papers should present approaches relying on computational
or mathematical models, and/or be supported by empirical
evaluations.
This call for papers will be distributed by means of mailing lists,
a web site, flyers at relevant conferences and personal contacts of
the guest editors.
Each submission will be reviewed by three referees. The referees
will be recruited among the constituent IEEE Technical Committee
members for Collaborative Intelligent Systems, the program committee
members of related conferences, and other experienced colleagues.
This special issue solicits, but is not limited to, papers on topics
that clearly address collaboration support systems, including:
* Human requirements for collaboration on distributed computers
* Organizational behaviors on collaboration support systems
* Formal and abstract models for collaboration support systems
* Role and group structures on collaboration support systems
* Objects and agents in collaboration support systems
* Multi-user interface design for collaboration support systems
* Analysis and evaluations of collaboration support systems
* Security and privacy issues in collaboration support systems
* Information sharing in collaboration support systems
* Software engineering for collaboration support systems
* Industry and enterprise application case study

eValid -- Some General Recommendations
Here are common eValid problem areas and references to pages that
provide general good-practice recommendations.
* Functional Testing Recording and playing scripts, with validation,
is a sure way to confirm operation of a web site or web
application.
o Protecting Login Account Names and Passwords
If you are recording logging into a site, eValid will need to
make a record of your account name and password. For the best
security, you should record login and password details in
encrypted form. There's an option in the Script Window Dialog
to turn on the Encoded Input option that protects critical
private information. See:
http://www.soft.com/eValid/Products/Documentation.5/Testing/encode.input.html>
o Initial State
Being a fully stateful recording and playback engine, eValid is
very sensitive to the initial state when playback begins. Here
are some recommendations about to manage your test's Initial
State effectively. See:
http://www.soft.com/eValid/Products/Documentation.5/Testing/initial.conditions.html
o Session Cookies
Session cookies are remembered inside eValid and the surest way
to clear them is to close eValid and launch it again.
o Modal Dialogs/Logins
Because of the nature of modal dialogs you may not be able to
use them directly. Instead, eValid provides a way to construct
a reliable script by creating the correct commands via the
Script Window Dialog. Check the documentation on modal dialog
support and on testing modal logins:
http://www.soft.com/eValid/Products/Documentation.5/Testing/modal.html
http://www.soft.com/eValid/Products/Documentation.5/Testing/modal.hints.html
o Opaque Objects
Certain objects are opaque relative to eValid's internal view of
web page properties, and have to be treated differently. These
object types include Java Applets and FLASH objects, discussed
here:
http://www.soft.com/eValid/Applications/java.applet/index.html
http://www.soft.com/eValid/Products/Documentation.5/Advanced.Testing/flash.cookbook.html
In addition, it may be helpful to see how to use eValid's
Application Mode:
http://www.soft.com/eValid/Products/Documentation.5/Advanced.Testing/application.mode.html
* Server Loading eValid applies load to a web server using the
capability to run multiple eValid browser instances.
o Machine Adjustments
If you want to get more than ~25 eValid copies running at on
time you probably need to make Machine Adjustments to optimize
your computer as a server loading engine. See:
http://www.soft.com/eValid/Products/Documentation.5/Loading/machine.html
o Ramping LoadTest Runs
The most common form of application includes ramping up server
load so you can study how the server performance degrades due to
increasing load.
http://www.soft.com/eValid/Products/Documentation.5/Loading/ramping.html
* Site Analysis eValid site analysis runs are a powerful way to
confirm website properties.
o Avoid Logout During Scan
A common problem during a site analysis scan is that eValid logs
you out before the scan is done! This happens when you start
the scan after logging into a protected area and the eValid
search spider navigates you to the "logout" page. The way to
avoid this is to make sure that your Blocked URLs List includes
"logout" and "signoff". See:
http://www.soft.com/eValid/Products/Documentation.5/Mapping/exclude.html

Mass Customization Information Systems in Business
A book edited by
Prof. Dr. Thorsten Blecker
Hamburg University of Technology (TUHH), Germany
&
Prof. Dr. Gerhard Friedrich
University of Klagenfurt, Austria
http://www.manufacturing.de/calls/mc-it.htm
Introduction:
Mass customization is a business strategy that aims at satisfying
individual customer needs with near mass production efficiency. The
advances realized in information technology are critical enablers,
which make this strategy function efficiently. Information systems
can be implemented to support diverse activities in the mass
customization value chain. They assist customers during the product
specification phase in order to lead them in a fast-paced manner to
the product variants corresponding to their individual requirements.
Modern information systems, which support open-innovation even
enable customers to participate actively in the product design.
Furthermore, mass customization information systems contribute to
helping companies mitigate excessive product variety and increase
costs' efficiency on the shop floor and logistics through optimal
product modeling and production planning and scheduling.
The Overall Objective of the Book:
In the fields of mass customization information systems, there
exists a need for a book enclosing high quality analyses in this
area. The scientific community and professionals both will benefit
from a book that focuses on this subject. This book should describe
the state-of-the-art, innovative theoretical frameworks, advanced
and successful implementations as well as latest empirical research
findings in the area. The main objective is to bridge theory and
practice on the one hand and to fill research gaps and answer open
questions on the other hand. The book will improve the understanding
of the problems that are encountered during the conception of
information systems for mass customization. Furthermore, it provides
solution approaches for the mitigation of these problems and
simultaneously highlights new directions for future research.
The Target Audience:
The target audience consists of professionals and scientists working
in the field of computer science and artificial intelligence. In
addition, industrial engineers and researchers in business
administration with a special focus on information systems and IT
Management will find this book as an adequate reference that
describes current research and presents topics that can be more
deepened in the future. Graduate students in the mentioned areas
will find practical applications of some theoretical concepts that
are already discussed in class.
Recommended topics include, but are not limited to, the following:
* Customer needs' elicitation
* Personalization and advisory systems
* Product modeling and configuration systems
* Customer Relationship-Management systems
* IT-Systems for Enterprise Resource Planning and
Supply Chain Management
* IT-architecture and infrastructure for mass customization
* IT-support for open innovation

23-24th September 2005
Loyola College Graduate Center, Columbia, MD (USA)
With a Special track theme:
Formal Methods in Human and Robotic Space Exploration
http://sttt.cs.uni-dortmund.de/isola2005
ISoLA is a forum for developers, users, and researchers to discuss
issues related to the adoption and use of rigorous tools for the
specification analysis, verification, certification, construction,
test, and maintenance of systems from the point of view of their
different application domains. To bridge the gap between designers
and developers of (formal methods based) rigorous tools, and users
in engineering and in other disciplines, it fosters and exploits
synergetic relationships among scientists, engineers, software
developers, decision makers, and other critical thinkers. In
particular, by providing a venue for the discussion of common
problems, requirements, algorithms, methodologies, and practices,
ISoLA aims at supporting researchers in their quest to improve the
utility, reliability, flexibility and efficiency of tools for
building systems and users in their search of adequate solutions to
their problems. Applications and case studies with a conceptual
message and experience papers with a clear link to tool construction
are all encouraged.
Particularly welcome are Regular contributions, Survey papers,

Web Services Challenge
Held at the IEEE Conference on e-Business Engineering (ICEBE-05)
Oct 18-20, 2005, Beijing, China
Supported by
IEEE Computer Society Technical Committee on Electronic Commerce (TCEC)
Centre for e-Transformation Research (CTR), Hong Kong Baptist University
Founder R&D Centre, Beijing
IBM China Research Lab
http://www.comp.hkbu.edu.hk/~ctr/wschallenge/
Background
Web services discovery and composition are two indispensable
capabilities required by the emerging service-oriented architecture
to enable the next-generation e-Business applications. Following
the great success of the first Web Services Challenge held in Hong
Kong in March 2005, a similar competition geared towards the
management of web services will be held at ICEBE 2005. The
competition solicits industry and academic researchers that develop
software components and/or intelligent agents that have the ability
to discover pertinent web services and compose them to create
higher-level functionality.
Competition Overview
This competition will be limited to syntactical matching based on
the Web Services Description Language (WSDL). Participants will be
required to *identify* and *compose* WSDL-specified services based
on their input and output messages as specified in a directory of
WSDL documents. Although the technical details of this second
contest will be similar to the first one, an enlarged web services
repository will be used for the evaluation. Each finalist will be
required to register and attend the conference to give presentation
and demonstration for final evaluation.
Competitors of Web Services Challenge will be evaluated based on the
*design* and *functional capabilities* of their component/agent.
(A) Design
Participants are required to submit a technical description of their
software agent or component of no more than 2 pages. This
description and local evaluation will be used to judge and rate the
design of the entry. The 2-page description should follow the IEEE
Computer Society format as specified by the main conference and will
be published as a poster paper in the general proceedings for all
accepted finalists.
(B) Functional capabilities
This challenge will be separated into the following two functional
competitions.
Competition A: Service Discovery Capabilities
Participants will be provided with a directory of web services
specifications and a specific discovery request as represented by
the provided input messages and the required output messages. The
participants component/agent will be required to find all services
that meet the requirements .
Competition B: Service Composition Capabilities
Given the same service repository provided in Competition A, the
participants will be provided with another discovery request. In
this competition, the request can only be fulfilled by the
composition of multiple services. The participant will be required
to supply the sequence and list of services that meet the
requirements.
Participants are encouraged to contact the competition chair to
express interest in the contest and the platform they plan to use
for the system development. More detailed technical description as
well as preliminary sample WSDL descriptions and service repository
can be found at
