MarketTools: An educational commodity marketing game
Agricultural commodity market participants make decisions in a risky and changing environment. Few agricultural producers use the diverse marketing alternatives available to them. Many are unfamiliar with the mechanics of the alternatives and methods for incorporating them into marketing strategies. This article describes MarketTools, an educational software package designed to support real-time, competitive marketing games. MarketTools simplifies record keeping and provides the basis for a structured approach to marketing education. The concluding section summarizes experience in using MarketTools in adult education and classroom settings. © 1995 by John Wiley & Sons, Inc.
A Commodity Market Simulation Game for Teaching Market Risk Management
Abstract The Market Risk Game is a computerized simulation game available for IBM PC and Apple II microcomputers that is designed to give realistic practice in making decisions in a risky market environment. It illustrates the use of hedging and put options to reduce risk in livestock and grain markets. It is best suited for individuals who have a basic understanding of commodity trading, but who need experience to solidify their knowledge to a functional level. Through the game, this is done without facing the risk of an actual investment or requiring the time involved in watching a market over an extended period.
Super-resolution of overlapped waves in time and frequency domain in a directional borehole radar measurement
The Multiple Signal Classification (MUSIC) algorithm is modified in order to resolve multiple waves and to estimate reflection points in 3-D space. This algorithm is suitable for directional borehole radar with a circular dipole array antenna. Making use of the spatial frequency difference of acquired array signals, the signals are decorrelated, and the 3-D MUSIC algorithm is applied. The time domain signals of the singlehole array-type borehole radar are used in order to form a measurement vector in the MUSIC algorithm. A computer simulation confirms that the proposed algorithm may estimate the directions of arrival (DOA) for three signals. Applying the proposed algorithm to field experiment data successfully estimates the DOA of a reflected wave from a fracture in rock.
