Nordic digital identification (eID)

This publication presents the survey results and policy recommendations of a Nordic study of national eID-systems. The countries that have been studied are Denmark, Finland, Iceland, Norway and Sweden. The aim of the study is to facilitate and lay a foundation for discussions about the similarities and differences in legal, organisational, technical and data approaches taken by the different countries. The survey data has been gathered with the assistance of the members of a project reference group. The data has been analysed and structured into a number of highlighted issues (chapter 1). The highlighted issues have been in turn used as baseline for a set of recommendations (chapter 9). The Nordic Council of Ministers has provided funding and facilitated the staffing of the reference group. The Norwegian Agency for Public Management and e-Government, Difi, has been the project owner and provided project resources

A computational iterative design method for bend-twist deformation in composite ship propeller blades for thrusters

This study investigates the feasibility of utilising common composite material layup techniques in ship propeller blade design to achieve an automatic pitch adjustment through bending-induced twist deformation. A comprehensive design approach, including various reinforcement materials and arrangements, was employed to attain the desired foil pitching, while minimising other undesirable deformation modes. The design process involved iterative computational analysis using finite element analysis and a deformation mode analysis based on foil shape parameters. The research showed that the proposed design approach effectively found options to improve the desired foil parameter pitch, while minimising undesirable deformation modes such as blade deflection and foil shape change. Furthermore, the proposed blade design was tested in thruster steering operational conditions and was found to have a pitch change well matched, potentially countering some changes in fluid flow. When compared to Kumar and Wurm’s design, which only focused on the angular orientation of glass reinforcement, the proposed design was found to outperform the twisting by achieving the same twist for a blade half the length. This study provides valuable insights into the utilisation of composite materials in ship propeller design and highlights the potential for further improvement through a composite engineering design approach.publishedVersio

Mobile Agent Security - Issues and Directions

Abstract. It is obvious that a prerequisite for use of mobile agent systems in many settings is that security is taken care of. A proper trust model is necessary in order to build security. A lot of security issues arise if the trust model implies that not all hosts are trusted. This paper discusses trust models, examines the security issues, and points at possible directions for solutions in terms of security services, mechanisms, and protocols. 1
