The Hugin Tool for Probabilistic Graphical Models
As the framework of probabilistic graphical models becomes increasingly popular for knowledge representation and inference, the need for efficient tools for its support is increasing. The Hugin Tool is a general purpose tool for construction, maintenance, and deployment of Bayesian networks and influence diagrams. This paper surveys the key functionality of the Hugin Tool and reports on new advances of the tool. Furthermore, an empirical analysis reports on the efficiency of the Hugin Tool on common inference and learning tasks.

The Hugin Tool for Learning Bayesian Networks
In this paper, we describe the Hugin Tool as an efficient tool for knowledge discovery through construction of Bayesian networks by fusion of data and domain expert knowledge. The Hugin Tool supports structural learning, parameter estimation, and adaptation of parameters in Bayesian networks. The performance of the Hugin Tool is illustrated using real-world Bayesian networks, commonly used examples from the literature, and randomly generated Bayesian networks.

A Tool to Support Collaborative Software Requirements Management
The system requirements specification (SRS) is a highly dynamic document that grows and evolves throughout a software development project, and it is critical that it be carefully engineered and managed. Because the SRS fulfils many roles and is of interest to a diversity of stakeholders, its management should be a collaborative process supported by an automated tool. Commercial requirements management tools are at present insufficiently versatile to support collaboration between a multidisciplinary and potentially distributed team of stakeholders. The requirements for such a collaborative tool are herein presented, alongside the design of a prototype and the findings of its application in a case study.

A Survey of Multimedia and Web Development Techniques and Methodology Usage
The authors present survey results which suggest that no uniform approach exists for multimedia systems development and that practitioners are not using the multimedia models cited in the literature. It is concluded that developers need new techniques that capture requirements and integrate them within a systems development framework.

Techniques and Methodologies for Multimedia Systems Development: A Survey of Industrial Practice
This paper tries to answer the question, how are multimedia systems being developed in practice? Herein are reported the findings of a preliminary postal survey of the top 1,000 companies from general industry and the principal 100 companies from the multimedia industry in Ireland, which reveal that there is no uniform approach to multimedia systems development and that approaches prescribed by the literature are not being used in practice. Nonetheless, the findings are clear that practitioners are favorably inclined toward the use of systematic methods and techniques for multimedia development. This survey paves the way for more detailed and insightful qualitative research into development practices.

Analysis of trapped entanglements in polymer networks
This work reviews different standard methods to analyze trapped entanglements of polymer networks and discusses their advantages and drawbacks with respect to simplicity, computing time and accuracy of the results. Since this standard analysis is based on the pairwise test of closed cycles, two algorithms for the determination of these cycles are introduced and compared. The decomposition into meshes creates unsolved problems regarding the non-ambiguity and the completeness of the received results. Examples are given in order to show their effects and to start further discussion to receive more convenient methods. As one possible solution Vassiliev's invariants are discussed and an approximation method is introduced to correct the possible multiple counting of entanglements.
