In a previous Computer column, "How Business Goals Drive Architectural Design" (Aug. 2007, pp. 101-103), an architecture-centric approach to software design in which the final architecture embodies the systemic properties and nonfunctional requirements that are critical to the application's success was proposed. Here, it is considered whether such an approach produces systems that are subsequently...
This paper illustrates how business goals can significantly impact a software management system's architecture without necessarily affecting its functionality. These goals include 1) supporting hardware devices from different manufacturers, 2) considering language, culture, and regulations of different markets, 3) assessing tradeoffs and risks to determine how the product should support these goals,...
Uncertainty pervades all aspects of engineering, and its management is of paramount importance. In software engineering, uncertainty can occur at many levels. It can appear in the software artifacts including requirements specifications, designs, and the code itself. Uncertainty can also manifest in the way we use tools, and in the engineering practices employed. It is even present in the life cycle...
This paper provides a review of state-of-the-art techniques and technologies associated with real-time automated visual inspection as applied in industrial situations. A survey of the most widely used machine vision algorithms is presented, with emphasis on those algorithms most suited to real-time application. Practical illumination schemes for real-time industrial inspection are also considered...
