Description This document describes the basic operation of a police radar gun and a few of the more popular ways to jam the radar gun. The conclusions are based on Matlab simulations of the radar gun and the jamming techniques.
Description Practical implementations of digital filters introduce errors due to finite-precision data and arithmetic. Many different structures, both for FIR and IIR filters, offer different trade-offs between computational complexity, memory use, precision, and error. Approximating the errors as additive noise provides fairly accurate estimates of the resulting quantization noise levels, which can be used both to predict the performance of a chosen implementation and to determine the precision needed to meet design requirements.
Description For middle school and up, a short course that explains acoustics (the physics of sound waves) as it relates to music and musical instruments. Suggestions for presenting some of the concepts to younger students are included.
Description "Concept Development Studies in Chemistry" is an on-line textbook for an Introductory General Chemistry course. Each module develops a central concept in Chemistry from experimental observations and inductive reasoning. This approach complements an interactive or active learning teaching approach.
Description Can DNA Barcodes help us identify and classify living things? Paul Hebert and colleagues have proposed DNA Barcodes as a way to identify bird species. Read on to explore their recent research article, "Identification of Birds through DNA Barcodes," published in PLoS Biology.
Description This report describes a systematic review of the process improvement literature, in and outside the substance abuse field, that hold evidence-based promise for significantly improving the nine Pathways to Recovery as defined by the Network for the Improvement of Addiction Treatment (NIATX). It was commissioned by NIATx and research began in July of 2004.
Description For organizations offering drug/alcohol addiction treatment, we are documenting successes and failures in building long term relationships with referral sources that result in increased admissions.
Description The goal of the Computational Sciences Lecture Series (CSLS) is to bring together researchers from mathematics (pure and applied), computer science, physics, and engineering to promote cross-fertilization between these fields and to establish computational science as an active research discipline at UW-Madison. The CSLS will consist of several half-day meetings during each year, each meeting consisting of three lectures by distinguished researchers, grouped around a common theme.
Description This course reviews the Discrete Fourier Transform and explains its practical use in frequency, spectral, and time-frequency analysis of signals. It gives an in-depth explanation of many Fast Fourier Transform (FFT) and FFT-based algorithms and a practical guide to their selection and use.

This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is often compared to “copyleft” free and open source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.
This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.
This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.

CC0 enables scientists, educators, artists and other creators and owners of copyright- or database-protected content to waive those interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright or database law.
