Building an Open Global Ranking Search Engine and Directory
Maxim Lifantsev
A new architecture for Internet searching, categorization,
and ranking
is proposed: it is to be contributed to, maintained, and controlled
collectively and consistently by all the people who create the
Web pages.
The basic idea is to capture opinions of very many people about
each Web
page in order to find out their weighted collective opinion
about the page;
and then use that opinion as the main part of page description
(together with its title, keywords, text, etc.) when making
a Web search.
Technically what is proposed, is a small addition to the HTML
standard
that lets people easily state their opinions about the information
on
the sites they create links (or bookmarks) to.
These opinions include the category to which the site belongs
and
the rank of the site in that category according to the person
making the link.
The opinions are weighted according to the author's reputation
in the field,
which in turn is also determined by such weighted opinions of
all the people
that have expressed such opinions.
A simple and uniform way of stating these opinions makes it easy
to create
a search engine and directory that can aggregate all these individual
opinions in different ways and provide the results utilizing
this collective
knowledge to everyone.
Basically, it is a global many-category collaborative ranking
system
with a self stabilizing and self enhancing peer review feedback.
The system can also be viewed as a consistent way to merge mini-directories
(bookmarks) of everyone who wishes to participate.

The Concurrency Factory Design and Development Environment
Xiaoqun Du
The Concurrency Factory is an integrated toolset
for the specification,
verification, and implementation of concurrent and distributed systems
such as
communication protocols and process control systems. The primary features
of
the Factory are its graphical user interface for specification and
simulation
of hierarchical networks of communicating state machines; its VPL textual
specification language for describing protocols involving complex data
structures and value passing; and its suite of analysis routines for
verifying
properties of specifications.

Real-time Deformation and Manipulation of Mass-spring and B-spline Volumes
through Haptic Interaction
McDonnell, Kevin T.
This paper presents a comparison of two techniques
for combining
physics-based modeling of elastic volumes with haptic rendering.
We
aim to permit the non-expert to interactively manipulate and deform
a
volumetric object with haptic-based tools. Our work shows that a pure
mass-spring model is not really well-suited for this purpose.
We
instead use an alternative formulation that employs both physics and
geometry that provides more natural control over volume interaction.

Wavelets-based Multiresolution Curve Editor
Qingyu Tang
I present a multiresolution curve editor, based on wavelets, that
conveniently supports a variety of operations: smoothing a curve;
editing the overall form of a curve while preserving its details. It
supports continuous levels of smoothing as well as direct manipulation
of an arbitrary portion of the curve; the control points, as well as
the discrete nature of the underlying hierarchical representation,
can
be hidden from the user. The multiresolution representation are both
simple and fast.
