Much of the detailed knowledge required to implement good Software Connguration Management systems has not been adequately cataloged and documented. The Design Pattern methodology provides a means to help rectify this deeciency. Based on the authors' experience in implementing Software Connguration Management tools, a selection of basic techniques for Software Connguration Management are presen...

This paper highlights some practical techniques for engineering design application development, which are critical to produce maintainable software design. The practices introduced in the paper are the result of long experience working with software development for engineering design applications. They have been recently employed and enhanced during the reconstruction of a well-known software f...

The architect Antonio Gaudi designed complex structures based on catenary systems. His beautiful forms were created by suspending pieces of string from hooks, deforming them with weights and other strings, then inverting the form to create the structural elements. Today’s architects are at a loss to reproduce these types of catenary forms when using even the most advanced design tools on the ma...

Computer-Aided Geometric Design modelers are now based on powerful mathematical curve and surface models, but there is still a considerable need for efficient tools to handle, analyze and modify these objects. Designing product shapes using geometric operations on free-form curves and surfaces is still a tedious task. Moreover, designers would prefer to use meaningful tools to concentrate on de...

An environmental monitoring system based on ZigBee wireless sensor network technology was researched in detail in this paper. Firstly, the technology working principle of ZigBee and its characteristics were introduced, and the characteristics of wireless sensor network and its application advantages were analyzed in comparison with the traditional network. Secondly, the overall scheme of the en...

The purpose for this article is to explore technology education from the perspective of the academic rationalist. Such an exploration is intended to provide information for technology educators who are grappling with education reform since it appears that the reforms of the 1980s are based on academic rationalism curriculum theory. This exploration includes consideration of the theoretical pers...

One of the products of engineering, besides constructed artifacts, is design documentation. To understand how design participants use documentation, we interviewed designers and typical documentation users and also took protocols of them both creating and using design documentation. Our protocols were taken from realistic projects of preliminary design for heating, ventilation and air condition...

Thickness accuracy of plate production depends on Automatic Gauge Control (AGC) in the plate mill area. A typical modern thickness control system design and implementation of a steel plate mill is discussed together with the impact on the design of process models, available measurements, available control actuators and material properties. A highlevel software design approach provides the abili...

This paper summarizes the rationale behind revision of an electronic design automation course and the resulting learning objectives and course model. Early experiences are highlighted.
