Vinod Goel [1] proposes a theory of notationality, derived from observations of interior designers, that distinguishes three classes of symbol systems: notational, non-notational, and discursive. He theorizes that design processes can be improved through the use of non-notational symbols. This paper presents the 2 factorial designed experiment used to test the applicability of this theory to el...

This book introduces a modern approach to embedded system design, presenting software design and hardware design in a unified manner. It covers trends and challenges, introduces the design and use of single-purpose...

Abstract. This paper provides an interpretation of interaction design patterns from the perspective of design-oriented research in information systems. It is concluded that interaction design patterns do not meet certain ideals for contemporary information systems design theory: Rigor, practical utility, novelty/innovation, acknowledgement of the social setting, and cumulative research. The lac...

A design pattern realization consists of a cluster of classes that work together to solve a particular problem using a well known, named solution. Developers may build systems out of several pattern realizations, and these pattern realizations may be interconnected, or, in other words, coupled. Coupled pattern realizations may represent a reasonable solution to software design problems, however...

In this paper, we analyze system-level design methodologies for platform-based design. Platform-based design is popular as a way to reduce development time, but creating the platform is difficult. We introduce the first generation dilemma problem --initial designs are much harder because we do many of the components that will be used to build the system. We explain the origin of this problem an...

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...
