CRYSALLIZING DESIGN INTENTIONS, USING CNC, LASER AND RAPID PROTOTYPING TECHNOLOGIES
The advances made in the Rapid Prototyping and CAD/CAM (including CNC and Laser) Technologies are now offering designers the privilege of building physical realities, at whatever scale, directly and automatically from computer files, with the explicit implications of speed, precision and flexibility.
TALAT Lecture 1201: Introduction to Aluminium as an Engineering Material
This lecture provides an introduction to metallurgical concepts necessary to understand how structural features of aluminium alloys are influenced by alloy composition, processing and heat treatment, and the basic affects of these parameters on the mechanical properties, and hence engineering applications, of the alloys. It is assumed that the reader has some elementary knowledge of physics, chemistry and mathematics.
Intermediate ear training for both the major and non-major, this Musicianship course is strongly recommended for students enrolled in theory classes. It provides an aural foundation to the theory presented in those classes. This musicianship course is typically paired up with a music theory course. Study materials on counterpoint are provided under Resources for your review. They offer an introduction to the modal counterpoint principles that guided composers during the medieval and renaissance
Data Tool Program
Data Tool is a data analysis tool for plotting and fitting data from laboratory experiments, simulations, video analysis, or any other data set organized into columns. A click of a checkbox in Data Tool allows the user to change the appearance of plots, see standard statistics for the data set or apply built-in linear, quadratic or cubic fits to the data set. Data Tool also includes a number of standard mathematical functions that can be applied to the data set, allowing for further analysis and
This resource consists of a Java applet and expository text. The applet allows the user to construct a histogram by clicking on a number line to generate the sample data. The class width can be varied and various summary statistics can be displayed.
This resource consists of a Java applet and expository text. The applet simulates the arrivals in a Poisson process during a time interval. The length of the interval and the rate of the process can be varied. The applet illustrates the Poisson distribution and a special case of the central limit theorem.
This resource consists of a Java applet and expository text. The applet simulates the time of the k'th arrival in a Poisson process. The arrival number k and the rate of the Poisson process can be varied. The applet illustrates the gamma distribution and a special case of the central limit theorem.
Galton Board Experiment
This resource consists of a Java applet and descriptive text. The applet illustrates Bernoulli trials in terms of a Galton Board. The number of trials and the probability of success can be varied. The random variables of interest are the number of successes and the probability of a success. The applet illustrates the binomial distribution, the law of large numbers and the central limit theorem.
Finite Order Statistic Experiment
This resource consists of a Java applet and expository text. The applet is a simulation of the experiment of selecting n objects at random from the first m positive integers. The random variables of interest are the order statistics. The applet illustrates the distributions of the order statistics.
This resource consists of a Java applet and expository text. The applet simulates rolling n dice. The random variables of interest are the sum of the scores, the maximum score, the minimum score, and the number of aces. The number of dice and the probability distribution that governs the dice can be specified. The applet illustrates various distributions and the central limit theorem.
Binomial Timeline Experiment
This resource consists of a Java applet and expository text. The applet simulates Bernoulli trials in terms of random points on a timeline. The random variables of interest are the number of successes and the proportion of successes. The number of trials and the probability of success can be varied. This applet illustrates the law of large numbers, the central limit theorem, and the binomial distribution.
Binomial Coin Experiment
This resource consist of a Java applet and expository text. The applet simulates Bernoulli trials in terms of coin tosses. The random variables of interest are the number of heads and the proportion of heads. The number of coins and the probability of heads can be varied. The applet illustrates the law of large numbers and the central limit theorem.
USGS Materials Maps
Visitors can learn about the relatively new field of imaging spectroscopy, which allows specific absorption features, caused by chemical bonds in materials, to be mapped spatially. Topics include an introduction to the procedure, environmental applications, vegetation and biota mapping, lithologic, and mineral mapping. A set of links provides access to reports, accompanied by spectroscopic images, on the use of this new tool in chosen locations.

Black Holes and Galaxies
Evidence has been accumulating for several decades that many galaxies harbor central mass concentrations that may be in the form of black holes with masses between a few million to a few billion time the mass of the Sun. Professor Reinhard Genzel discussed measurements over the last two decades, employing high resolution infrared and radio imaging and spectroscopy on large ground-based telescopes that prove the existence of such a massive black hole in the Centre of our Milky Way, beyond any rea
Quelles machines pour enseigner la langue ?
This paper first presents a history of Computer-Assisted Learning (CAL), setting its origins in the 1920s with the invention of mechanical learning machines. The use of the computer then allowed the development of different types of language learning activities: comprehension tasks, simulations, etc. However, without the contribution of natural language processing (NLP), these activities are of limited use. We address the problem of the integration of NLP in CALL systems while summing up the cha
