The role and extent of adult education in community colleges were examined in this paper. The literature indicated no common definition of adult education except that it involves lifelong learning. One source identified five forces causing adults to seek further education. They are: basic education, degree objective, occupational training, homemaking education, and avocation and geriatric courses. Unfortunately, development of adult education programs at community colleges is often frustrated...

An application of two-dimensional Fourier Transform correlation for the attitude measurement of three-dimensional objects is considered. Included are geometric optical equations and geometric translation and rotation equations necessary for the image error calculations. Minimum attitude resolution equations are developed to estimate image quantization necessary for a given measurement error. These techniques are then applied as an additional measurement to the radar tracking problem. (Author)

This article tells the story of a writer for whom "voice" is an important element that he feels he once had but has lost in his writing. The article mostly places the blame on his trying to please teachers and professors and listening to their comments about his writing. It quotes many scholars (such as Lev Vygotsky and Jerome Bruner) and authors (such as Truman Capote and T.S. Eliot) on just what "voice" is, but the writer's own definition does not exactly satisfy him. It...

Over 50% of American universities have special programs for high risk or disadvantaged students, most of whom come from different ethnic or cultural backgrounds and whose educational and economic background is considered markedly inferior to that of regular university students. Many of these programs, however, are token efforts, e.g., 100 high risk students in a student body of 20,000. Although the most common characteristic of high risk students is a lack of funds, their economic deficiency...

The first section deals with the appearance of dielectric relaxation time constant components. These arise when the drift length of holes becomes comparable to the electrode separation, so that a significant fraction of the photogenerated holes is swept from the crystal. Under these conditions, which correspond to having the photoconductive gain of the order of or greater than unity, there is a maximum D* bandwidth product. The second section is concerned with the D* bandwidth calculation and...

Two methods are described for estimating the probability that a given semiconductor device will be damaged by an electrical transient. Both methods are based on existing device damage data which were obtained by step-stressing devices to failure, using rectangular pulses. Both methods require calculation of the time-dependent power waveform in the device, due to application of the transient. One method employs only the largest peak of this power waveform, while the other includes the entire...

The report details insertion loss measurements from multiple types of hearing protection devices in order to examine the nonlinearity of insertion loss. Tests were conducted in continuous noise from 55 to 130 decibels (dB) and impulsive noise from 110 to 170 dB peak sound pressure levels. Results show that predictive models for the protective capacity of hearing protection should account for variability in insertion loss, depending on the incident sound pressure level.
