Deriving structurally based software measures

Where the Truth Lies: AOP and Its Impact on Software Modularity

“…It should be also noted that the original versions perform better with regard to the aggregate coupling and cohesion, since the measures of vocabulary size grew in all cases, due to the introduction of aspects. Nevertheless, aggregate coupling does not satisfy the second axiom of Fenton & Melton [14] for coupling measures. That axiom states that system coupling should be independent from the number of modules in the system.…”

Estimating the quality of functional programs: an empirical investigation

“…As mentioned earlier, similar experiments to these have been performed for imperative languages within di erent application domains 3,6,7]. The programme of work described here has been in uenced by these experiments, particularly those partially funded by the Alvey Software Reliability M o d e l l i n g Project and the ESPRIT REQUEST project 7].…”

“…Metrics based on internal attributes are often employed in the belief that there is a strong correlation between internal attributes and the desired external attributes. Internal attributes such as length, modularity, reuse, coupling and cohesion are much easier to measure than external attributes, and some work has already been done on correlating internal and external attributes for programs written in imperative languages 3,6,7]. The experiment described here used established statistical techniques to ascertain whether or not there is any correlation between a selection of internal attributes (based on length and modularity) and certain characteristics of the development process, such a s t h e n umber of errors found during development, which are assumed to be indicative o f q u a l i t y.…”

“…The image analysis domain was chosen 3 because it o ers a particularly wide variety of distinct problems for software engineering and we already had expertise in the development of image processing algorithms in C 8]. The subset of algorithms examined so far has included low level algorithms which operate on an image array and produce image arrays as output (for example, convolution algorithms) and intermediate level algorithms which operate on image arrays and produce symbolic output (for example, curvilinear feature extraction algorithms).As mentioned earlier, similar experiments to these have been performed for imperative languages within di erent application domains 3,6,7].

Australian Cosmic Ray Modulation Research

“…A new air shower experiment was therefore installed in the central plateau region of Tasmania at Liawenee (Fenton et al 1981(Fenton et al , 1982Murakami et al 1984). This experiment showed that the southern hemisphere sidereal response was much smaller than that in the northern hemisphere at 0·02% (Fenton et al 1990), which was to have important implications for understanding the structure of sidereal anisotropies (see Section 7 below).…”
