Currently, open source software communities are thriving and the number of projects that are available through well known code repositories is rapidly increasing over the years. The amount of code that is freely available to developers facilitates high reuse opportunities. One of the major concerns of developers when reusing code is the quality of the code that is going to be reused. Design pat...

In this article, we introduce a new concept in HERMES, the FP7 funded project in Europe, in developing technology innovations towards computer aided memory management via intelligent computation, and helping elderly people to overcome their decline in cognitive capabilities. In this project, an integrated computer aided memory management system is being developed from a strong interdisciplinary...

A structural health monitoring system is developed for continuous online monitoring of delamination initiation and growth in composite structures. Structural health monitoring problems are often cast in the context of a statistical pattern recognition paradigm, in which a damage state of a structure is inferred by comparing test data with baseline data. However, subtle signal changes due to dam...

Educational design patterns describe reusable solutions to the design of learning tasks and environments. While there are many projects producing patterns, there are few approaches dealing with supporting the instructor/user in instantiating and running those patterns on learning management systems (LMS). This paper aims to make a leap forward in this direction by presenting two different metho...

Post Project Reviews (PPRs) are a rich source of knowledge and data for organisations if organisations have the time and resources to analyse them. Too often these reports are stored, unread by many who could benefit from them. PPR reports attempt to document the project experience – both good and bad. If these reports were analysed collectively, they may expose important detail, e.g. recurring...

We introduce P-MARt, a repository of pattern-like micro-architetcures. The purpose of P-MARt is to serve as baseline to assess the precision and recall of pattern identification tools. Indeed, several approaches have been proposed to identify occurrences of design patterns, yet few have been independently validated for precision and recall for lack of known occurrences. We hope that P-MARt can ...

Although one can find several pattern recognition techniques out there, there is still room for improvements and new approaches. In this book chapter, we revisited the Optimum-Path Forest (OPF) classifier, which has been evaluated over the last years in a number of applications that consider supervised, semi-supervised and unsupervised learning problems. We also presented a brief compilation of...

Much of the detailed knowledge required to implement good Software Connguration Management systems has not been adequately cataloged and documented. The Design Pattern methodology provides a means to help rectify this deeciency. Based on the authors' experience in implementing Software Connguration Management tools, a selection of basic techniques for Software Connguration Management are presen...

Abstract: We use the pattern recognition algorithm of Lo et al. (2000) with some modifications to determine whether “head-and-shoulders” price patterns have predictive power for future stock returns. The modifications include the use of filters based on typical price patterns identified by a technical analyst. With data from the S&P 500 and the Russell 2000 over the period 1990-1999 we find str...

According to a definition found in the summary of the Workshop on Adaptable and Adaptive Software[LL95]: “A program is called adaptive if it changes its behaviour automatically according to its context”. Within this context, we restrict our research domain to the automatic runtime adaptation of existing behaviours. In this paper, we propose an Adaptive Strategy Design Pattern that can be used t...
