Fearn. Aerodynamics 1.1 provides a collection of computational tools for solving steady two-dimensional potential-flow over an airfoil using panel methods. Over thirty functions are defined to facilitate the computation of airfoil geometry, influence coefficients, aerodynamic coefficients and presentation graphics. Additionally, three panel methods are fully ... MathSource: Packages and Programs Wed, 27 Jan 2010 14:22:28 -0600 http://library.wolfram.com/infocenter/MathSource/7586/ Contributed by: Chris Niemann. Briefly, this submission is an extension of my last three submissions. I have extended the number of unknowns and equations for quaternions, octonions and sedenions. These are 4, 8 and 16 dimensional numbers, first described by Sir William Rowan Hamilton, then extended by his student, Arthur Caley. Once again, I have used the Transformation matrices corresponding to ...

Using any prime number desired, a general system of linear equations may be solved. The Eight-Step method is once again used to find all inverses. If a given system has no solution, a message to that effect is printed. Otherwise, the system has a solution and the standard equations can be utilized to find all solutions.

FRED, stands for Federal Reserve Economic Data, a database of 20,318 U.S. economic time series. This is a brief description, with some examples, of how to create a function to download FRED data. In order to proceed with this example you will need to obtain an API key from the Federal Reserve Bank of St Louis. Details on how to obtain an API key can be found ...

The Chicago Board Options Exchange® (CBOE®) Volatility Index®, also known as the VIX, is a benchmark for U.S. stock market volatility. The VIX is based on the S&P 500® Index, and estimates expected volatility by averaging the weighted prices of SPX puts and calls over a wide range of strike prices. The CBOE has a whitepaper describing a step by step calculation ...

SmartCAE Heat Transmission is simulation software for the calculation of steady and transient heat transmission through multilayered walls. This is particularly useful for industrial applications, R&D, and education. The package extends Mathematica for the calculation of heat transmission, and can also be used with Mathematica Player Pro. Technical Notes Thu, 14 Jan 2010 16:00:54 -0600
