ME297: DESIGN THEORY AND METHODOLOGY SEMINAR
on Wednesday, 6 October 1999, 3:15pm
http://cdr.stanford.edu/DD/Courses/me297/
Instrumenting the Design-Learning Environment:
From Pragmatic Results to Philosophical Foundations
Professor Larry Leifer
For over fifteen years the Stanford University Center for Design
Research has been focused on the formal study of engineering product
development teams at work in academic and corporate settings. This
seminar session is based on experience gained from one such effort,
the implementation of team-based, global learning techniques in a
Stanford University School of Engineering course, ME210abc (now ME210,
ME310ab), "Global Team-Based Design-Development with Corporate
Partners". The course is distributed internationally by the Stanford
Instructional Television Network (SCPD-SITN) for on-campus Stanford
students, globally distributed campuses and global industry based part
time students.
Applied ethnography methods like video interaction analysis have been
used to reveal the detail and pattern of activity of design teams.
Computational support systems have been developed to facilitate their
work. Throughout these studies we have seen that their activity
closely resembles the most attractive aspects of self-paced education
described by constructivist learning theorists. Their design
environment has been instrumented to see if technical and behavioral
interventions did, in fact, improve performance. It is this learning
validation phase of our work, and its dependence on technology, both
for collaborative learning and for assessing performance outcomes,
that will be the focus of this talk.
To put the findings in context, I will introduce the pedagogic
framework that guides our value judgments and the technology framework
that defines the design requirements for our learning environment. I
will define and elaborate on the concept and practice of
"Product-Based-Learning" (PBL) and the feedback instrumentation model
we use for assessing PBL performance. Within this framework, the
discussion will focus on technology specific issues, the rationale for
technical intervention, and a sampling of performance assessment
results.
Biography: A member of the Stanford faculty since 1976, Larry Leifer
teaches graduate level courses including the Design Theory and
Methodology Forum for graduate students in Design Research. He is
founding director of the Stanford Center for Design Research (CDR)
where he does design theoretic research. Special interests include: 1)
development of a collaborative engineering environment for
geographically distributed product development teams; 2)
instrumentation of that environment for design knowledge capture,
indexing, assessment and reuse; 3) development of tele-assistive
robots for physically limited individuals; and 4) development of
design requirements for high performance learning environments. Based
in part on the results of his experimental approach to curriculum
reform, Professor Leifer was appointed founding director (July'97) of
the Stanford University Learning Laboratory (Office of the Stanford
President and Provost) charged with systematic exploration of the role
that technology can play in the personalization and enhancement of the
learning experience of Stanford students, anytime, anywhere.

Electronic Commerce:
From Economic and Game Theoretic Models to Working Protocols
Moshe Tennenholtz
Technion
Israel Institute of Technology
The design of protocols for non-cooperative computational environments
(e.g. Internet Auctions) is a major challenge for electronic commerce.
In order to address this challenge we should tackle several
complementary tasks: 1. Re-consider economic mechanisms in view of
their use in computational settings. 2. Incorporate distributed
systems features into the context of game-theoretic and economic
models. 3. Deal with computational aspects of mechanism design. In
this talk we present a (biased) overview of some of the work carried
out on these tasks. In particular, we will consider the effects of
having many participants, risk elements, and competition among sellers
in the Internet setup, on the study of auctions. In addition, we
consider the effects of the communication network and the asynchronous
nature of distributed systems on the implementation and analysis of
various economic mechanisms. Some results about the computational
treatment of economic mechanisms will be mentioned as well.
Biography: Moshe Tennenholtz received his B.Sc. in Mathematics from
Tel-Aviv University (1986), and his M.Sc. and Ph.D (1987,1991) from
the department of Applied Mathematics and Computer Science in Weizmann
Institute. He spent one year as a post-doctoral research affiliate,
and one year as a research associate at the Robotics Laboratory of the
Computer Science Department at Stanford University. In 1993 he joined
the faculty of industrial engineering and management at the Technion--
Israel Institute of Technology. His work is concerned with the
foundations of multi-agent systems. In particular, in joint work with
colleagues and students he introduced and developed theories of
artificial social systems, co-learning, and qualitative
decision-making. His recent line of research is concerned with the
adaptation of economic models to computerized/AI settings.

Perception of virtual sources
Ville Pulkki
Amplitude-panned virtual sources are spatially spread to some extent.
In this work the spread is measured using listening tests and
objective tools. In the conducted method-of-adjustment tests virtual
sources are generated using two loudspeakers. The listener adjusts the
direction of the virtual source to match best with a present real
source with same narrow band signal. The listening test results are
analyzed using a binaural auditory model. The combined results show
that amplitude-panned virtual sources are stable and behave as the
panning laws expect at low frequencies due to stable ITD cues. At
frequencies between 700 Hz and 2000 Hz the virtual source is spread
and its localization depends on signal type because ITD and ILD cues
suggest highly differing directions. At high frequencies the
amplitude-panned virtual source is perceived differently between
individuals. This happens because at high frequencies, where
localization depends mostly on the ILD cue, amplitude panning produces
highly differing and oscillating ILD cues to different individuals. In
these results there is also new information of how directional
information on ITD and ILD cues are combined in human auditory
mechanisms to form the direction perception.

Multiple-Language-Acquisition-System (MLAS):
An Infant Simulator
Tetsuo Suga
Department of Psychology, Nihon Joshi University
"Children are the only things (living or non-living) that are able to
attain the close-to-adult language proficiency by the age of 4-5
years" (L. Gleitman and P. Bloom, 1999). The NLP systems already
published such as Shrdlu, SAM, and so on showed remarkable linguistic
performances, but the performances were based upon lexical data and
syntactic rules equipped by researchers in advance. Language
acquisition system to simulate children should start with no
ready-made linguistic resources and acquire its linguistic knowledge
step by step for itself. I try to elucidate the hurdles concerning
morphological transformation, syntactic transformation, and lexical
meaning (above all the pragmatic aspect of it) which prevent us to
design such a system, and show how to overcome the difficulties
through demonstration of Multi-Language- Acquisition-System (MLAS) I
have investigated for years and which may be capable to attain about
4-5 years level of ability in any human language (English, Japanese,
French, and so on).

On the Applications of Security Models
George W. Dinolt
Lockheed Martin Trusted Systems Laboratory
San Jose, CA 95129
Policies and mathematical models of those policies have been a staple
of computer security research for more than 25 years. Policies have
ranged from the "High Water Mark" to the "Chinese Wall" to "Non
Interference" with occasional mathematical models to match.
We build mathematical models of security policies because our hope is
that the models will be useful in the design and construction of the
system at hand. Unfortunately, the results of the application of
models on implementations is often at best minimal. In many cases
model development and system design go on concurrently, with the model
often lagging the system design. At worst, the modeling was purely an
academic exercise.
There have been several successes in the applications of security
models to system design and construction. In these cases, the security
model has driven the design in specific directions. In one case that I
worked on, we used the model and formal design to derive a series of
assumptions about the implementation and the code.
In this talk I will discuss a framework for using mathematical models
of security for building secure computer systems, even systems where
code development is not driven directly by the model. I will give
several examples of models and show how they can be used to influence
the design and construction of systems.
As part of the framework I will discuss some of the qualities which a
useful security model should have. I will compare several models on
the basis of these qualities.
One part of the discussion might have some bearing on the current
emphasis on "Open Source Software." "Open Source" is not enough to
ensure quality and correctness. Computer Systems are often too complex
to analyze by eye and hand. Without means and mechanisms for the
analysis of both the design and the implementations, the best that
"Open Source" by itself can achieve is software studied by many
"eyes." This is better than not looking, but may not be enough for
high assurance systems.
Biography: George W. Dinolt is Chief Scientist at the Trusted Systems
Lab at Lockheed Martin Management & Data Systems Western Region. From
1972 to 1982 he was an Assistant then Associate and finally Adjunct
Professor in the Department of Mathematics at the University of
Michigan-Dearborn. From 1977 to 1982 he was software engineer,
software tool builder and software systems builder at the Engineering
Computing Center at Ford Motor Company. Since 1982 he has been at Ford
Aerospace Western Development Labs/Loral Western Development
Labs/Lockheed Martin Management & Data Systems Western Region. While
there he was one of the developers on the Multinet Gateway program, a
multilevel secure IP packet switching system designed to meet A1
levels of assurance. He has been involved in research on the
application of formal methods to the design and implementation of
secure computer based systems. He has published several papers in the
computer security area, been on several program committees for
conferences, has been Program Chair for the IEEE Symposium on Security
and Privacy and has been Research Track Chair for the NISSC. He holds
B.A., M.A. and Ph.D. degrees all in mathematics.

Visual Language: Global Communication for the 21st Century
Robert Horn
Stanford CSLI
Bob Horn will discuss his new book in which he claims an entirely new
language is emerging around the globe; a language that tightly
combines words and visual elements. On the world wide web, this visual
language has become widely used-and misused, so it has significant
implications for interface design. Horn claims that it is becoming a
new international auxiliary language, one that we will use in addition
to our native languages to communicate across cultural divides. Visual
language has already developed an elaborate syntax and semantics and
it is rapidly integrating vocabularies as diverse as diagraming and
cartooning into a single unified communicative tool. Horn claims that
visual language has been continuously invented over the past two
centuries to handle the increasingly complex communication about our
technology and organizations. He will illustrate part of his talk with
his recent invention of argumentation maps, large poster-size
diagrams, which enable students and instructors to navigate the Turing
debate about whether computers will ever be able to think.
Biography: Robert E. Horn is a researcher, former CEO, and author. For
the past few years, he has been a visiting scholar at the Program on
People, Computers, and Design of the Center for the Study of Language
and Information, Stanford University. His new book is "Visual
Language: Global Communication for the 21st Century" and the Turing
argumentation maps, "Mapping Great Debates: Can Computers Think?"

Fuzzy Queries in Multimedia Database Systems
Ron Fagin
IBM Almaden Research Center
There are essential differences between multimedia databases (which
may contain complicated objects, such as images), and traditional
databases. These differences lead to interesting new issues, and in
particular cause us to consider new types of queries. For example, in
a multimedia database it is reasonable and natural to ask for images
that are somehow "similar to" some fixed image. Furthermore, there are
different ways of obtaining and accessing information in a multimedia
database than information in a traditional database. For example, in a
multimedia database, it might be reasonable to have a query that asks
for, say, the top 10 images that are similar to a fixed image. This is
in contrast to a relational database, where the answer to a query is
simply a set. In this talk, we survey some new issues that arise for
multimedia queries. This talk, which will be completely
self-contained, was an invited talk at the 1998 ACM Symposium on
Principles of Database Systems.
Biography: Ronald Fagin is manager of the Foundations of Computer
Science group at the IBM Almaden Research Center in San Jose,
California. He received his B.A. degree in mathematics from Dartmouth
College in 1967 and his Ph.D. in mathematics, with his thesis in
finite-model theory, from the University of California at Berkeley in
1973.

STANFORD TALK
on Monday, 11 October 1999, 3:00pm-4:00pm
Encina Hall, the Bechtel Conference Room
(up the main entry stairs and straight ahead)
Technological Innovation:
From Concept Cars to Racing Cars
The Stanford Department of Mechanical Engineering, the Department of
Aeronautics and Astronautics, the Center for Design Research and the
BMW Technology Office USA are pleased to announce a special
presentation by Dr. Mario Theissen, Technical Director for BMW
Motorsport (past director of advanced product development).
The issues and examples will be of interest to Stanford's advanced
technology research community, to technology entrepreneurs and to
students interested in advanced automotive industry career paths.
BMW's recently revived motorsport racing program has met with great
success, including a win at the 1999 24-hour LeMans race and victory
at Sears Point in the American LeMans series. With motorsports being
a primary testing ground for pioneering innovations in the automotive
industry, it has been a natural transition for Dr. Theissen to draw
upon his experience as the former director of BMW's Global Product
Innovation Centers in this new arena. He would like to share insights
regarding the topics of advanced product engineering and its
relationship to racing success.
This talk is open to all with special reference to Stanford faculty,
staff and students.
Following the presentation, from 4:00pm to 5:00pm, you are invited to
join the speaker for an open display of the 1999 BMW LMR race car that
won the LeMans race earlier this year and will be raced at Laguna Seca
this coming weekend, October 9,10. Dr. Theissen will be available for
questions about his presentation, the vehicle, and BMW's Motorsport
program.

Modular Reconfigurable Robotics
Mark Yim
Xerox PARC
Modular, self-reconfigurable robots are those that are made up of a
large number of modules, but a small number of module types. As the
number of modules increases, these systems show promise of great
versatility, robustness and low cost. However, to make this realizable
there are many computational and manufacturing issues that must be
addressed.
We will show the progress of two modular reconfigurable robot systems;
PolyBot and Proteo, and present some of the issues in applying them to
a search and rescue task and a shape configuration task respectively.
These tasks are rich in interesting problems in motion planning in
unstructured environments, distributed computation and control, robust
redundant actuation and control, computational geometry, and image
understanding/sensor fusion.
Biography: Mark Yim has been a researcher at the Xerox Palo Alto
Research Center (PARC) since 1996. Currently, he leads a government
funded project building a modular, reconfigurable robot system at
PARC. He has recently authored a book chapter on robots for kids. He
has published in journals and conferences in the areas of mobile robot
planning, distributed robotics, optimal control, MEMS, and haptic
devices. He has authored over 20 patents. His work on MEMS and
robotics has been featured in the New York Times, USA Today, Discovery
Channel, BBC news and MSNBC. He has been nominated as one of the
TR100, the top 100 young innovators by Technology Review Magazine. He
received his PhD in mechanical engineering from Stanford University in
1994.

Lore: A Database Management System for XML
Jennifer Widom
Database Group Faculty
Over the past several years database researchers have explored issues
in managing schema-less "semistructured" data: data that may be
irregular or incomplete, and whose structure may evolve rapidly and
unpredictably. The Lore system at Stanford, under research and
development for the past 4 years, is a full-featured DBMS designed
specifically for semistructured data. Fortuitously, Lore's original
data model, called the Object Exchange Model (OEM), is very similar to
W3C's new eXtensible Markup Language (XML), and we have just completed
migrating Lore to full XML compliance.
I will provide an overview of the Lore system and will briefly
highlight some of its more challenging and novel aspects: Lore's
expressive OQL-based query language, indexing capabilities, cost-based
query optimizer, dynamic structural summaries, and proximity search
capabilities. The talk will be followed by a demonstration of Lore's
stand-alone capabilities, and (time permitting) a demonstration of
Lore serving as an XML engine behind a Microsoft prepackaged XML demo.
To find out more about Lore or experiment with the online demos please
visit http://www-db.stanford.edu/lore
The talk presents joint work with Jason McHugh and Roy Goldman.
Biography: Jennifer Widom received her Bachelors degree from the
Indiana University School of Music in 1982 and her Ph.D. from Cornell
University in 1987. From 1987-88 she was a Visiting Assistant
Professor in the Computer Science Department at Cornell. She spent
five years as a Research Staff Member at the IBM Almaden Research
Center before joining the Stanford faculty in 1993.
