2.1 Systems thinking: the first step

The processes of analysis and synthesis in conventional thinking are based on the concept of an object. An object is something that can be clearly distinguished from its environment and can be characterised by its attributes. Attributes enable categorisation schemes that are the basis of our normal thinking. So when you look at a particular ecosystem, for example a pond, you find different animals and plants. And if you look at any ‘book of the pond’ you find each a

Software design of maintainable knowledge-based systems for building design
Identifying and establishing a basic structure for knowledge representation is one of the keys to successful design of knowledge-based computer systems. In Building Design and Construction, this initial knowledge structure can be achieved by utilizing a query driven approach to software engineering. As (user) queries reflect the user's demand for in/output, it is natural to link the overall user dialogue with key elements in the knowledge base direct connections between user screen and objects i

The Pattern That Connects
While patterns have a spotty history in architecture, their definitions and uses in other fields offer new possibilities for design. This paper examines those definitions and uses?including theories put forward by architectural theorist, Christopher Alexander; art educator, Gyorgy Kepes; chemist, Ilya Prigogine; and anthropologist, Gregory Bateson. Of particular interest is the shift from eternal, essential, universal, and fundamental patterns to fleeting, superficial, specific, and incidental v

3 Reading articles for mathematical information

We gain much of our mathematical information from our surroundings, including reading newspaper and magazine articles. A skill that will be useful to all of us in our studies is the ability to do this in a structured way, as it is very easy to be uncritical of the information that we see. Newspapers and magazines frequently place mathematical information in the form of graphs and diagrams. All too often, we tend to assume that the information is correct, without questioning possible bias or i

Determining the impact of cad drafting tools on the building delivery process
Computer aided design is intended to change the way design and construction are carried out. at a minimum, this implies savings realized in terms of time spent and improvement of the quality of designs produced. to test this idea, we hypothesized that computer aided drafting and design operations may be instrumental in reducing the number of change orders issued and help control cost overruns by improving the accuracy of constr

Design Tool Integration: Model Flexibility for the Building Profession
The development of ICAtect, as discussed in the Building Systems Automation and Integration Symposium of 1991, provides a way of integrating simulation tools through a common building model. However, ICAtect is only a small step towards the ultimate goal of total integration and automation of the building design process. In this paper we investigate the next steps on the path toward integration. We examine how models structured to capture the physical attributes of the building, as required by s

1.1 Thoughts on a PhD

Entering students often think of a PhD as a ‘magnum opus’, a brilliant research project culminating in a great work. This is rather a demanding model, and few students win Nobel Prizes as a result of their doctoral studies. More realistically, a PhD is research training leading to a research qualification. The PhD is a passport to a research career.

There are other views of a PhD, as well. Getting a PhD can be a ‘rite of passage’, prerequisite to admission into the academic ‘t
