Explores the subject of fractal geometry focusing on the occurrence of fractal-like shapes in the natural world. Topics include iterated functions, chaos theory, the Lorenz attractor, logistic maps, the Mandelbrot set, and mini-Mandelbrot sets. Provides appropriate computer algorithms, as well as further sources of information. (JJK)

Described are improvements for the computer efficiency of the two midpoint scan-conversion algorithms used to draw ellipses. Included are computer programs written in C programing language. (JJK)

Describes computerized differential classifications of a variety of subtle brain dysfunctions. Provides objective corroboration that may be a useful adjunct to psychiatric diagnoses. Discusses independent criteria for diagnostic validity, evaluation of treatment efficacy and more individualized treatment. Outlines the implications of this…

Illustrates how muMATH can be used for manipulating abstract differentiation rules, optimization, implicit differentiation, related rules, and verifying the chain rule. (MVL)

Defines basic typographic terminology and offers two classroom projects using microcomputers to create and use type. Discusses typeface, type families, type style, type size, and type font. Examples of student projects that include the creation of bulletin board displays and page-size maps. (KO)

Discusses the nature of a nuclear magnetic resonance (NMR) experiment, the techniques used, the types of structural and dynamic information obtained, and how one can view and refine structures using computer graphics techniques in combination with NMR data. Provides several spectra and a computer graphics image from B-form DNA. (MVL)
