You're an evil man. Linus Torvalds
Thank you.

Publications

A complete list of my papers can be found on my "bio" page . You can download various papers by me and my previous students on image processing and wavelets and numerical methods for partial differential equations and related topics.

Courses

• MA 303, Fall 2008
• CS/MA 615: Numerical Methods for Partial Differential Equations
• Math 692B: Wavelets and Image Processing, Fall 2000

  • Test Images

Test Images

High quality, grey-scale, test images for purposes of testing algorithms on natural images. Some results from my compression program are given.

The original Kodak Photo CD Photo Sampler color images from which the greyscale images above were derived. If anyone can tell me a standard way to convert these to YUV, YCrCb, or RGB, I'd be interested. Later note: it seems that various versions of Photoshop have good color conversion between Kodak Photo CD format and RGB, so that is what I used for the color versions. I'm still not happy with Photoshop's conversion to grey-scale.

Software

• Software for the numerical approximation of solutions of elliptic and parabolic partial differential equations (from CS 615).
• Schelog, an embedding of Prolog into Scheme that was written by Dorai Sitaram, adapted for Gambit-C.
• Beating the Averages by Paul Graham tells how to beat your competitors using Lisp. He also wrote Revenge of the Nerds.
• Design Patterns in Dynamic Programming by Peter Norvig explains why many of the classical design patterns used in C++ or Java are trivial or not needed in dynamic languages like Common Lisp, Scheme, and Dylan, and presents new, more powerful, design patterns for dynamic languages. Later addition: Richard P. Gabriel, a strong proponent of design patterns in computer programming, claims that the Gang of Four "Design Patterns" book for C++ and Java programmers helps "losers lose less", and that design patterns (lower case) are powerful techniques for organizing computer programs, even in dynamic programming languages.
• A Common Lisp tutorial.
• Lawrence Lessig talks about how extensions to copyright terms over the last 40 years form theft from the public; how software patents are holding back innovation; how small losses to copyright holders are leading to federal proposals of legal vigilantism, where corporations are given free rein to hack your computer; and what you can do about it.
• An interesting essay about several things: the history of the computer gaming industry, the importance of computer games in motivating learning about computers, and how open-sourcing computer games would increase innovation and progress.
• There are blog aggregators for Lisp and Scheme blogs.
• Why Lisp?

What graduate students should do after qualifiers

Some, if not most, areas of mathematics require "intermediate-level" material before going on to study recent papers and write a thesis. Here is my advice for students who think they may be interested in various fields. Other faculty members will have their own lists, I'm sure.

• Wavelets and image processing: Second course in real analysis (MA 545), functional analysis (MA 546 or 611). Depending on your interests, Probability and Statistics (MA 538/539, Stat 567); Image Processing (ECE 637/641); Partial Differential Equations, Convex Analysis, and Numerical Methods (MA 642/643, MA/CS 615, Brezis's Operateurs Maximaux Monotones et Semi-Groupes de Contractions dans les Espaces de Hilbert)
• Numerical methods for partial differential equations: Second course in real analysis (MA 545), applied functional analysis (MA 611), partial differential equations (MA 642), CS 615 or the equivalent math course.
• Applied partial differential equations: Second course in real analysis (MA 545), applied functional analysis (MA 611), partial differential equations (MA 642).

Books

• The West Lafayette campus of Purdue University has purchased a site license for the book Basic Concepts of Mathematics by Elias Zakon, published by The Trillia Group, an online publishing house I founded. This book helps the student complete the transition from purely manipulative to rigorous mathematics while covering the following topics: basic set theory, induction, quantifiers, properties of the real numbers (including consequences of the completeness axiom), fields, and basic properties of n-dimensional Euclidean spaces; the online index gives more information about the contents. Under the terms of the site license, this text can be used without charge by any student or member of the faculty or staff of the West Lafayette Campus of Purdue University. Other schools buying site licenses for Basic Concepts of Mathematics include the University of Windsor and Swarthmore College.
• The Trillia Group has also published the second book in the Zakon Series on Mathematical Analysis, Zakon's Mathematical Analysis I (which covers metric spaces, continuity, differentiation and integration; its index is online), and An Introduction to the Theory of Numbers by Leo Moser. Added November, 2006: I'll be using Mathematical Analysis I as the text for MA 504 in Spring 2007; the West Lafayette campus of Purdue has now bought a site license for this book, so any students (including those in MA 504) or staff on that campus can download and use it for free.

Magazines

• I've been reading Maisonneuve magazine for a few years now. It's an english-language journal out of Montreal. In my opinion it's smarter and sharper than, e.g., Harper's or the Atlantic Monthly.
• Recently I discovered Seed magazine, which deals with the intersection of science and culture. Also out of Montreal, but this you can't really tell by the content. Later addition: After a hiatus, back in print.
• Other magazines of interest include Adbusters (against corporatist culture), Geist (overtly Canadian), and SubTerrain (raw, "urban", writing), all out of Vancouver.
• Check out Cabinet, a "Quarterly of Art and Culture." It's fantastic. I presume it takes its name from a Victorian "curiosity cabinet." Eclectic, everything is of interest.
• Finally, there's Granta, which has, on average, the best writing of any periodical. Often has themed issues of particular interest.

Personal

The government of Australia is paying Enviromission a billion Australian dollars to build the "Solar Chimney", a solar power plant that will provide enough power for 200,000 homes and will be the tallest structure in the world. Time Magazine chose this project as one of its Best Inventions of 2002. Schlaich Bergermann und Partner is the consulting engineering firm for the project; their description of their device can be found here. From their web site, it appears they have been working on this technology since the early 80s---they built a prototype in Spain in 1981/82. Note: It's 2008, and Enviromission isn't any closer to building the tower.

My father, Robert Lucier, invented such a device in the mid 70s and patented it in several countries; the US patent was first filed in 1975 and granted in 1981 (full text here); the Australian patent application was filed in 1976 and granted in 1979; the Canadian patent was granted in 1978; the Israeli patent application was filed in 1976 and granted in 1979.
