The modeling and simulation of physical systems is of key importance in many areas of science and engineering, and thus can benefit from high-quality software tools. In previous research we have demonstrated how functional programming can form the basis of an expressive language for causal hybrid modeling and simulation. There is a growing realization, however, that a move toward non-causal mod...

This paper reviews methodological innovation in qualitative research. It comprises a narrative review of 57 papers published between 2000-2009 in which claims to innovation in qualitative methods have been made. These papers encompass creative methods, narrative methods, mixed methods, online/e-research methods and software tools. The majority of claims of innovation are made for new methods or...

As Scala gains popularity, there is growing interest in programming tools for it. Such tools often require call graphs. However, call graph construction algorithms in the literature do not handle Scala features, such as traits and abstract type members. Applying existing call graph construction algorithms to the JVM bytecodes generated by the Scala compiler produces very imprecise results due t...

This article presents some reflections on the development of push services and technologies over the Internet, based on work done by the authors in the Swisscast research project from 1997 to 2000 (www.swisscast.net). About five years ago push services were seen as a major trend in Internet communication. Users so it seemed would simply have to subscribe to a series of these services; then, the...

Bayesian networks are a theoretically well-founded approach to represent large multi-variate probability distributions, and have proven useful in a broad range of applications. While several software tools for visualizing and editing Bayesian networks exist, they have important weaknesses when it comes to enabling users to clearly understand and compare conditional probability tables in the con...

Linda Shields PhD, FRCNA, Professor of Nursing, University of Limerick, Ireland This is one of a series of short papers on aspects of research by Alison Twycross and Linda Shields Just because a research study has been published in a journal does not mean that it is good research or that the results are applicable to your area of clinical practice. When reading a paper, it is necessary to consi...

Since record polymorphism is one of essential factors for object-oriented languages, various approaches to incorporate record polymorphism into type systems have been proposed to lay the foundation for object-oriented languages. Recursive types, which are essentially types of lists or trees, are major programming tools. In object-oriented languages, a pseudo variable \self" has a recursive type...

Meeting the demand for dynamic ubiquitous computing applications requires programming abstractions and development tools tailored to this unique environment. This paper provides a programming framework tailored for ubiquitous computing applications that allows developers to express their applications’ needs in terms of interactive application sessions. These sessions are defined by a set of ope...
