We show a new approach, based on the utilization of Mathematica, to solve gas permeation problems using membranes. We start with the design of a membrane unit for the separation of a multicomponent mixture. The built-in Mathematica function, FindRoot, allows one to solve seven simultaneous equations instead of using the iterative approach of…

In process control education, particularly in the field of chemical engineering, there is an inherent need for industrially relevant hands-on apparatuses that enable one to bridge the gap between the theoretical content of coursework and real-world applications. At the University of South Carolina, two experimental air-pressure tank systems have…

Describes an optional course on applied electrostatics that was offered to electrical engineers in their final year. Topics included the determination of electric fields, nature of the charging process, static electricity in liquids, solid state processes, charged particle applications, and electrostatic ignition. (GS)

This report presents national estimates of employment of scientists, engineers, and technicians (SETs) in manufacturing industries in 1983. The estimates are provided as data in five charts and three detailed statistical tables. Data in charts include: SETs by sector of employment; employment growth in high-technology and other manufacturing…

Designed for use by individuals enrolled in vocational agricultural classes, these student materials deal with setting up and using a tripod level, staking out foundations, differential leveling, and staking out fence lines. Topics covered in the unit are different kinds of tripod levels, the parts of a tripod level, transporting a tripod level,…

Describes recent experiments at Cornell University; at schools in East Cleveland, Tennessee, North Carolina, and Kentucky; and at Middle Island School in Brookhaven, New York. (MLF)

Outlines how classification systems or codes, operating in a variety of contexts, regulate the interaction between man and the built environment. Views the ritual forms of the built environment as transmitters of culture. Suggests that this framework might provide a new starting point for investigations into the built environment in use and the…

Discusses records made of the London Weather Centre indicative of concentrated sunshine symmetrically about noon, which provides a probability of sunshine occurring on vertical surfaces to be greatest for south facing walls. Concludes that design recommendations should be based on available, rather than on theoretically possible, sunshine duration…

Working jointly with area colleges that give course credit for the project, a number of consulting engineering firms bring students into their offices for a series of orientation sessions. (Author/MLF)

Summarizes data on the numbers of women and minority engineers, including Black, Spanish surnamed, Oriental, American Indian, and disadvantaged groups. Indicates taht their future prospects will become even brighter, but problems of attracting more women and Blacks into engineering are significantly greater than in cases of other minority groups.…

The cities of the world are great engineering feats. From the earliest dwellings of man constructed out of the raw materials of the environment, man has used his ingenuity to work engineering wonders that improve the circumstances of human life. By engineering technological skills, human beings have altered the environment to suit varied…

This memorandum contains engineering information relevant to the use of communication satellites for educational purposes. Information is provided for ground terminals as well as satellites. Satellite related issues addressed include: (1) expected life of service of various satellites, (2) constraints on the availability of the satellites, (3)…

Describes recently published Engineering Science Development Unit (ESDU) texts, intended to promote an applied science approach to sixth form teaching. Each text has two components: a main story in which an engineering problem or situation is considered, and a set of supporting material covering development of physical relationships. (MLH)

Outlines the academic responsibilities connected with the nation's transition to the metric system and indicates how these responsibilities relate to the general task of problem solving. (GS)
