Microscopic measurement of surface topography is a continuing need in microfabrication technology and materials research. The aim of this research is to adapt the scanning electron microscope (SEM) to the quantitative measurement of a wide range of surface structures. The SEM is a widely used measurement tool in materials science and semiconductor fabrication. The SEM's strength is that it prov ...

Reuse in software engineering is an exciting concept that has yet to be reliably implemented. The number of program subroutines that are truly generic (and therefore applicable across all applications) is limited. However, there are specific applications that are required by many organizations, albeit with a set of constraints specific to each organization. This project proposes to design a too ...

Digital imagery is an increasingly prevalent in the computerized workplace; however, the increasing volume of this data is stressing storage and communications systems. One of the most competitive solutions to these stresses is wavelet-based data compression. A wide variety of wavelet image compression methods exists, and given an application, there is a need to compare different methods before ...

It is proposed to develop a miniature guarded hot plate apparatus that can be used to determine the thermal conductivity or thermal resistance of very small specimens (1 to 3 cm square) of thermal insulation materials over a temperature range from at least -40 degrees Celsius to +65 degrees Celsius, with the apparatus having the capability to carry out measurements under controlled environments of ...

A combustion environment can be described by a characteristic fuel-to-air ratio normalized by the stoichiometric fuel-to-air ratio, otherwise defined as an equivalence ratio, _. The equivalence ratio is used extensively in a wide range of combustion fields from fundamental flame studies, to full-scale fire testing, to power plant operations. There have been basically two methods for calculating ...

During the last two decades, software to support the manufacturing lifecycle has become pervasive. Sophisticated off the shelf packages are available for most standard manufacturing activities such as MRP, inventory control and dynamic scheduling. Unfortunately, most of this software has been developed in isolation by independent vendors and does not interoperate well with other independently de ...
