Pattern languages where originally conceived by the architecture community (Alexander, 1977) and since the early 1990’s have been widely used to document software development practise. While most of these patterns have centred on the technical aspects of software some authors have moved beyond the purely technical aspects, e.g. Coplien and Harrison (2003) have used patterns to discuss issues of...

Cooperation of heterogeneous legacy information systems in organizations is a reality, offering to users a unified access to heterogeneous and distributed information. Our goal is to capitalize design knowledge involved in cooperative application development and to define cooperation patterns adapted from Fowler’s analysis patterns. These patterns, derived from ACSIS cooperative architecture, a...

The stock selection problem is one of the major issues in the investment industry, which is mainly solved by analyzing financial ratios. However, considering the complexity and imprecise patterns of the stock market, obvious and easy-to-understand investment rules, based on fundamental analysis, are difficult to obtain. Fundamental and technical analyses are two common methods for predicting th...

The Technical Lead needs to have a thorough understanding of the quality of the software and control over destabilising forces that can effect the delivery. Systems are large, the Lead cannot know everything and there is tendency for lots of small incremental changes to sum to large requirements. This paper presents set of three patterns and their relationships (Code Surfing, Core Sampling and ...

Technical analysis is the art of identifying patterns in historical data with the belief that certain patterns foretell future price movements. An empirical evaluation of the effectiveness of technical analysis is confounded by the subjectivity involved in identifying patterns. This work presents a robust framework for pattern identification using probabilistic neural networks (PNN). The thirty...

What type of technical progress is able to increase income per capita, instead of merely translating into higher fertility? To investigate this question, this paper first sets up an OLG growth model with capital, land and endogenous fertility. At each date, children compete with physical capital as a means of saving for the young. This framework is then put into motion by continuous neutral and...

A megamodel is a model, whose instances are systems of models and intermodel relationships. To be independent of a particular modeling language, typical megamodels reduce models and their relationships to unstructured nodes and edges, thus creating a significant gap between abstract megamodels and their concrete instances. We address this gap problem by mathematical means borrowed from category...
