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.
Offshore Hydromechanics includes the following modules: 1. Hydrostatics, static floating stability, constant 2-D potential flow of ideal fluids, and flows in real fluids. Introduction to resistance and propulsion of ships. Review of linear regular and irregular wave theory. 2. Analytical and numerical means to determine the flow around, forces on, and motions of floating bodies in waves. 3. Higher order potential theory and inclusion of non-linear effects in ship motions. Applications to motio
The Thin Blue Line-Forensic Scientists
This site draws on, and brings together, many scientific disciplines-identification of hairs and fibers, forensic psychology,DNA testing, photography, bloodstain pattern analysis, and computer forensics-that contribute to the integrated analysis of a crime and the physical evidence left at a crime scene.

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
India and China: Can two tigers share a mountain?
To outsiders, India and China show some striking similarities. Both are ancient civilizations reincarnated as modern republics in the mid twentieth century, and are now rising powers. Both have nuclear weapons, burgeoning economies, expanding military budgets and large reservoirs of manpower, and seem to be vying for influence in the Indian Ocean, the Persian Gulf, Africa, Central Asia and East Asia. Yet little attention is paid to the relationships between them. (From India and China: Conflict
The Trading System in Crisis: The Threat from Proliferating Preferences
Preferential trading arrangements are becoming increasingly popular among the nations of the world. But are they a positive development? In the Fourth H W Arndt Memorial Lecture – presented by the ANU College of Asia and the Pacific and the ANU College of Business and Economics – Professor Jagdish Bhagwati argues that bilateral, sub-regional and regional free trade agreements, and the granting of one-way preferences to developing countries of choice, are crea
