ABSTRACT
At present there are numerous report program generators, most of which are quite similar in purpose and in method of operation. Although they generally relieve the programmer from concern with detailed program logic, they nevertheless require him to have intimate knowledge of the characteristics of his data base, the kinds of entries he wants extracted, the manipulations to be performed, and the detailed format of the desired report. Furthermore, as report program generators have become more generalized (and thus more flexible), they have also become more complex, requiring the user to furnish complicated specification statements in coded form. This, of course, demands an increased amount of training and experience on the part of the programmer, and makes his source programs more subject to error.

Compose & conquer: modularity for end-users
ICSE '10: Proceedings of the 32nd ACM/IEEE International Conference on Software Engineering - Volume 2Users have vast amounts of information at their disposal and access to many tools that can compute on that data. Often, no particular program can fulfill a user's needs; or, when such a program exists, it may be too obscure for the user to find. When ...

Can dynamic neural filters produce pseudo-random sequences?
ICANN'05: Proceedings of the 15th international conference on Artificial Neural Networks: biological Inspirations - Volume Part IDynamic neural filters (DNFs) are recurrent networks of binary neurons. Under proper conditions of their synaptic matrix they are known to generate exponentially large cycles. We show that choosing the synaptic matrix to be a random orthogonal one, the ...
