True 3D animation for displaying VLSI modeling data

The authors report on a flexible system that provides visual feedback to VLSI designers with a novel display method. The basic problem is to display simultaneously two or more functions f ₁, f₂, . . ., each of which depends on the two spatial variables x and y. The method is based on results from visual perception experiments, which indicated that the human visual system can view simultaneously two or more images that are separated in depth, even if they are combined (superimposed) over a common spatial domain. Two display modes have been implemented: a gray-level mode and a contour mode in which only the edges separating adjacent regions are displayed in an effort to make things easier for the user. This depth-separation technique allows the viewer to register spatially the x,y distribution of multiple variables in an animation sequence. The technique can be applied to many other situations in which a single-plane episode involves several variables     

Model of the flow in a circular jet developing in a cross stream. Solution of the initial length problem

A flow model and an integral method of calculating the initial length of a circular jet in a cross stream are proposed. The results of calculating the characteristics of the initial length are in satisfactory agreement with the experimental data.Translated from Inzhenerno-Fizieheskii Zhurnal, Vol. 54, No. 6, pp. 905–912, June, 1988.     

Stability of everyday memory in age-associated memory impairment: A longitudinal study.

Everyday memory performance was examined longitudinally in 2 groups of Ss meeting the diagnostic criteria for age-associated memory impairment (AAMI). One group of 157 participants in a drug trial for reversing memory loss in AAMI was tested over multiple sessions. The other group of 75 persons did not participate in a drug trial and thus was tested only twice. Both groups were retested for longitudinal follow-up about 4 yrs after initial session. Follow-up test performance remained fairly stable relative to initial performance in both groups. The drug study group showed large practice effects during the course of the drug studies, but these effects subsided after the drug studies' end. Implications regarding memory decline in the normal elderly and neuropsychological measurement issues are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The Macintosh Programmer's Workshop

The authors discuss the Macintosh Programmer's Workshop (MPW), a Macintosh development environment that includes a comprehensive set of programming tools and handles several languages. It also combines the graphical interface common to all Macintosh applications, a command language similar to the Unix shell languages, and Smalltalk's immediate execution of commands in any window. They focus on the program-development environment rather than on the tools in that environment. They give the history of MPW, and describe its design goals. The bulk of the article is a discussion of MPW's design
