In many science and engineering undergraduate programmes, physics courses are fundamental and can be seen as a potential place where students can develop complementary abilities such as the computational thinking process. The present work proposes and describes the learning science and engineering with electronic spreadsheets cycle (LSEESC)…

Animation is the rapid display of a sequence of static images that creates the illusion of movement. This optical illusion is often called perception of motion, persistence of vision, illusion of motion, or short-range apparent motion. The phenomenon occurs when the eye is exposed to rapidly changing still images, with each image being changed…

Argues for a legitimate role of manually expressed engineering graphics within engineering education as a needed support for computer-assisted drafting work. Discusses what and how students should learn as well as trends in engineering graphics education. Compares and contrasts manual and computer drafting methods. (CW)

Offers a method for interactive design of objects on a computer. Outlines a method which allows the designer to interact with orthogonal views to construct a three dimensional model of an arbitrary shape. Presents an algorithm based on the Bezier curves to efficiently create smooth curves and surfaces. (CW)

Presents the results of statistical analyses and interpretations of data obtained from students in two engineering fundamentals courses on an attitudinal survey. Indicates positive and significant improvement in student attitudes toward their own drawing abilities and the importance of drawing in their lives and careers. (CW)

A technique is described for the generation of perspective views of three-dimensional models using computer graphics. The technique is applied to models of familiar thermodynamic phase diagrams and the results are presented for the ideal gas and van der Waals equations of state as well as the properties of liquid water and steam from the Steam…

Describes a simulated computer-aided-graphics (CAD) program at The Pennsylvania State University. Rationale for the program, facilities, microcomputer equipment (Apple) used, and development of a software package for simulating applied engineering graphics are considered. (JN)

Computer programs that generate projections of thermodynamic phase surfaces through computer graphics were used to produce diagrams representing properties of water and steam and the pressure-volume-temperature behavior of most of the common equations of state. The program, program options emphasizing thermodynamic features of interest, and…

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)

Advances four propositions in an effort to provide a frame of reference for a new generation of interactive engineering graphics scholars. Suggests the integration of traditional engineering graphics with new production tools such as computer-aided design drafting. Proposes that graphics problem-solving educational opportunities be maximized. (CW)

Demonstrates one method for finding parallel tangents to a cylinder based on geometric properties of the three dimensional representation of the cylinders. Uses rotational transformations to obtain a three dimensional view. Provides a starting point for those studying geometric methods as a lead into computer assisted drafting. (CW)

Describes a computer program which allows students to specify rather arbitrary sets of poles and zeros for the transfer function of a linear system. The computer evaluates/plots the systems impulse and step responses individually and displays them in reduced form along with the pole-zero plot. (JN)

In introductory mechanics courses it is often necessary to know the geometric properties of some irregular figure. An interactive program (using an Apple II microcomputer) which allows an instructor to determine the geometric properties of an arbitrary figure is described. Includes mathematical formulation, properties of irregular polygons, and…

Explores several concepts in computer assisted design/computer assisted manufacturing (CAD/CAM). Defines, evaluates, reviews and compares advanced computer-aided geometric modeling and analysis techniques. Presents the results of a survey to establish the capabilities of minicomputer based-systems with the CAD/CAM packages evaluated. (CW)

Presents current trends in the development of expert systems within the Department of the Navy, particularly research into expert graphics systems intended to support the Authoring Instructional Methods (AIM) research project. Defines artificial intelligence and expert systems. Discusses the operations and functions of the Navy's intelligent…
