Two major areas of the scorecard development process were identified as having much capacity for improving credit scoring models. These are the application of 1) better classifiers and 2) variable selection techniques. However, the application of an artificial immune system for developing scorecards as well as the use of other variable selection techniques, other than stepwise regression, in credit scoring are quite limited as indicated by the scarcity of published materials in these two areas in the current literature.

In the dissertation, we consider the problem of finding the shortest path between two points along a sequence of adjacent triangles in a general setting. The sequence of triangles is replaced by a sequence of ordered line segments. The 3D space is replaced by a Euclidean space.

The second aim of the study was to find out the correlation between students’ MI scores and their vocabulary learning strategy use. Before analyzing the correlation, it was found that Intrapersonal intelligence was the most dominant type among participants, while Mathematical Intelligence was the least used one. Pearson correlation was performed to see the potential relation between two variables.

Since data representation is one of the factors that affect the training and testing time, a compact and complete detector generation algorithm is investigated; the thesis investigates optimal algorithms to generate detector set in AIS; they help to reduce both training time and detecting time of AIS-based IDSs.

An important chapter in the theory of distribution of zeros of entire functions pertains to the study of linear operators acting on entire functions. This dissertation presents new results involving not only linear, but also some non-linear operators.
