    • Features of Mobile Diabetes Applications: Review of the Literature and Analysis of Current Applications Compared Against Evidence-Based Guidelines 

      Chomutare, Taridzo; Fernandez-Luque, Luis; Årsand, Eirik; Hartvigsen, Gunnar (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Background: Interest in mobile health (mHealth) applications for self-management of diabetes is growing. In July 2009, we found 60 diabetes applications on iTunes for iPhone; by February 2011 the number had increased by more than 400% to 260. Other mobile platforms reflect a similar trend. Despite the growth, research on both the design and the use of diabetes mHealth applications is scarce. ...

    • File repository transfer protocol. Version 1 

      Stabell-Kulø, Tage (Research report; Forskningsrapport, 1995-02)
      This document presents and specifies the protocol that interfaces clients and servers in the File Repository (FR). The FR is a software system that supports sharing of files. The protocol is modelled after Smtp and Nntp and is encoded in Ascii. No details of server implementation is visible in the protocol description, but we state our intentions at several occasions.

      Johansen, Håvard; Van Renesse, Robbert; Vigfusson, Ymir; Johansen, Dag (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06)
      An attacker who controls a computer in an overlay network can effectively control the entire overlay network if the mechanism managing membership information can successfully be targeted. This article describes Fireflies, an overlay network protocol that fights such attacks by organizing members in a verifiable pseudorandom structure so that an intruder cannot incorrectly modify the membership views ...

    • FirePatch. Secure and time-critical dissemination of patches 

      Johansen, Håvard; Rennesse, Robbert van; Johansen, Dag (Research report; Forskningsrapport, 2006)
      Because software security patches relay information about vulnerabilities, they can be reverse engineered into exploits. Tools for doing this already exist. As a result, there is a race between hackers and end-users to first obtain patches. In this paper we present and evaluate FirePatch, an intrusion-tolerant dissemination mechanism that combines encryption, replication, and sandboxing such that ...

    • First steps towards solving the café problem 

      Ellingsen, Mariel Evelyn Markussen (Mastergradsoppgave; Master thesis, 2022-06-08)
      Hearing loss, and assistive technologies to compensate for the loss, are becoming more and more regular. Hearing aids have improved the quality of life for many suffering from hearing loss but are still insufficient in some social settings. The café problem rises when there are a group of people talking in a relatively noisy environment where one person has hearing aids. Even with modern advancements, ...
