The emergence of the three-input majority gate as a practical element for logical design has demanded a useful method of design using these elements. In order to facilitate the use of this gate, a digital computer program is presented to implement the design procedure. Utilizing the truth table of a...
A representation for the process of mechanical design,
along with its computer implementation is presented and
discussed. The representation consists of three
fundamental concepts: design objects, constraints, and
decisions. The design objects are the structures with
which the physical artifacts of the design are described.
A design object consists of...
In recent years, there has been an extensive effort to develop low-cost implementations
of radio frequency integrated circuits for consumer applications. This thesis is a
research effort in the design and implementation of integrated RF CMOS Power Amplifiers
(PAs). A significant challenge in the implementation of RF CMOS ICs is...
A number of computational tools now exist to aid in developing conceptual solutions based on a functional description of a design problem. A key limitation of these tools is the way results are organized for presentation to the user. In general, results are an undifferentiated mass of potential solutions. Analysis...
Computers have made a great contribution to the
design process in various applications, such as design
analysis and simulation. A new technology called
Computer-aided design (CAD) has helped the designer to
design and build very intricate systems.
While most of CAD software is run on workstations or
microcomputers with one...
The fundamental objective of a design engineer in performing tolerance technology is to transform functional requirements into tolerances on individual parts based on existing data and algorithms for design tolerance analysis and synthesis. The transformation of functional requirements into tolerances must also consider the existing process capabilities and manufacturing costs...
The systems currently available for forest road design are not capable of making computer-aided design judgments such as: 1) automated generation of alternative grade lines, 2) optimizing vertical alignment, 3) minimizing total cost of construction, maintenance, and transportation costs, and 4) aiming for least environmental impacts. In recent years, advances...
The sketching software developed in this thesis, is aimed to serve as an intelligent design tool for the conceptual design stage of the mechanical design process. This sketching software, Sketch Pad for Windows, closely mimics the traditional paper-and-pencil sketching environment by allowing the user to sketch freely on the computer...
The primary goal of any model is to emulate, as closely as possible, the desired behavioral phenomena of the real system but still maintain some tangible qualities between the parameters of the model and the system response. In keeping with this directive, models by their very nature migrate towards increasing...
A system which allows the computer to capture sketches
made by a mechanical designer is described. The system not
only recognizes basic features as they are sketched, but it
also reasons the spatial relationships between features and
builds a high level abstract representation (feature model)
of the artifact. The temporal...
