This research aims to understand deeply the unique features of the CAD/CAM media tools and their applications, and come up with an initial framework of architectural design and construction process involving the use of CAD/CAM fabrication aids.

This research is targeted towards the provision of support for designers in achieving, and measuring , Buildability whilst allowing for design Creativity and learning . This paper deals with the development of Skill Models as an approach to measuring Buildability in a CAD produced design . A Skill Model is specific to one construction task . A library of Skill Models is required for full measur...

A case of pulmonary embolism in which the diagnosis was aided by transthorasic echocardiography is described. Echocardiography may be helpful in emergency presentations, as ECG changes can be neither sensitive nor specific for the diagnosis of acute massive pulmonary embolism.

Volume 4, Issue 3, May – June 2015 Page 106 ABESTRACT In recent years, various researchers have come up with different ways and means to integrate CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing). The selection of machining parameters is an important process planning function for manufacturing processes.Typically, machining parameter selection is done manually. The user still ...

In reverse engineering, complex free-form shaped parts are usually digitized quickly and accurately using the newly arisen non-contact measuring methods. However, it produces extremely dense point data at a great rate. Not all the point data are necessary for generating a surface CAD model. Moreover, owing to inefficiencies in storing and manipulating them it takes a long time to generate a sur...

The significance of the design process in determining the success or failure of a product in the market place is becoming increasingly more articulated. Consequently companies are implementing and developing new techniques and tools to support design more effectively. Design research is directed at gaining a greater understanding of design, ultimately to better support it through the developmen...

One of the central issues of intelligent CAD is building a modeling mechanism that deals with various models . The world in which a model is built, which call ontology, may vary over domains of modeling, abstraction levels . and granularities . This paper discusses integration of design object models over multiple ontologies . The key idea is the use of meta-level model about relationships amon...

This paper describes the initial development of a concept inventory for Engineering Graphics. As instructional methods continue to evolve in the area of graphics, there is a need for a concept inventory instrument that is able to measure the students’ misconceptions of important graphical concepts. In a 2014 Delphi study, CAD was identified as an important component of the graphics curriculum t...

Design representation is not only used to document the final design for construction; it is essential for the development and communication of design ideas. With recent developments in CAD and communications technologies, the way we represent and visualize designs is changing. In this paper we canvass the results of experiments examining the effect of different communication channels in collabo...

Vertical keiretsu’, characterized by suppliers’ willingness to make customized investments and their long-term relationships with manufacturers, had been recognized as an important source of strength in Japanese industries. Our model predicts that, in contrast to the recent popular argument, the information-technology revolution can strengthen ‘vertical keiretsu’. This is because the efficiency...
