    • WallMon : Interactive distributed monitoring of process-level resource usage on display and compute clusters 

      Nilsen, Arild (Master thesis; Mastergradsoppgave, 2011-11)
      To achieve low overhead, traditional cluster monitoring systems sample data at low frequencies and with coarse granularity. However, interactive monitoring requires frequent (up to 60 Hz) sampling of fine-grained data and visualization tools that can explore and display data in near real-time. This makes traditional cluster monitoring systems unsuited for interactive monitoring of distributed cluster ...

    • WANTED! – Virtual Coach for People with Thorny Diseases 

      Halonen, Raija; Savenstedt, Stefan; Hartvigsen, Gunnar; Abächerli, Roger; Jääskeläinen, Erika; Synnes, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-03)
      The main objective of this study was to propose a concept for a virtual coach to be used by people who suffer from costly and challenging diseases such as dementia, depression, diabetes and cardiac related issues, and by their caretakers presenting healthcare service providers or family members of the people suffering from the named diseases. Those listed diseases form almost an unbearable ...

    • We.Tree - Connecting young individuals with Type 1 Diabetes Mellitus in rural areas through serious games 

      Sørensen, Mats Christian (Master thesis; Mastergradsoppgave, 2015-12-15)
      Young individuals with chronic diseases living in rural areas might face additional problems in their everyday life compared to those in the same position living closer to the cities. Living far away from friends, relatives, other in the same situation, or even general practitioners and specialists may act as an extra burden in their process through their situation. This project is meant to aid ...

    • Weakly supervised semantic segmentation for MRI: exploring the advantages and disadvantages of class activation maps for biological image segmentation with soft boundaries 

      Syed, Shaheen; Anderssen, Kathryn Elizabeth; Stormo, Svein Kristian; Kranz, Mathias (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-02-13)
      Fully supervised semantic segmentation models require pixel-level annotations that are costly to obtain. As a remedy, weakly supervised semantic segmentation has been proposed, where image-level labels and class activation maps (CAM) can detect discriminative regions for specific class objects. In this paper, we evaluated several CAM methods applied to different convolutional neural networks (CNN) ...

    • Wearable Sensors with Possibilities for Data Exchange: Analyzing Statusand Needs of Different Actors in Mobile Health Monitoring Systems 

      Muzny, Miroslav; Henriksen, André; Giordanengo, Alain; Mužík, Jan; Grøttland, Astrid; Blixgård, Håvard Kvalvåg; Hartvigsen, Gunnar; Årsand, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-31)
      <i>Background</i> - Wearable devices with an ability to collect various type of physiological data are increasingly becoming seamlessly integrated into everyday life of people. In the area of electronic health (eHealth), many of these devices provide remote transfer of health data, as a result of the increasing need for ambulatory monitoring of patients. This has a potential to reduce the cost ...

    • Weather-aware Wake-up of Sleeping Cyber-Physical IoT Nodes 

      Kristensen, Steffen Ole Randrup; Bjørndalen, John Markus; Rais, Issam; Ha, Hoai Phuong; Anshus, Otto Johan (Chapter; Bokkapittel, 2023-09-27)
      Cyber-physical IoT nodes located in environments which are resource-constrained and physically hard to access, like the Arctic tundra, must achieve long operational lifetimes from a single battery and report data over data networks. The nodes sleep most of the time, and only wake up to perform mission tasks, including reporting data. However, networks can become unavailable, or have low bandwidth ...

    • What Do We Know About the Use of Chatbots for Public Health? 

      Gabarron, Elia; Larbi, Dillys; Denecke, Kerstin; Årsand, Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      <i>Background and objective</i>: The number of publications on the use of chatbots for health is recently increasing, however to our knowledge, there are no publications summarizing what is known about using chatbots for public health yet. The objective of this work is to provide an overview of the existing scientific literature on the use of chatbots for public health, for which purpose have chatbots ...

    • What motivates patients with NCDs to follow up their treatment? 

      Henriksen, André; Woldaregay, Ashenafi Zebene; Issom, David-Zacharie; Sato, Keiichi; Årsand, Eirik; Bradway, Meghan; Pfuhl, Gerit; Pelagatti, Susanna; Hartvigsen, Gunnar (Conference object; Konferansebidrag, 2021-05)
      The increasing use of mobile health (mHealth) tools for self-management is considered to be important to improve health effects for patients with chronic NCDs (noncommunicable diseases). This development is supported by an increasing number of available mHealth apps. The apps range from disease management apps (e.g., diabetes diary) to health and fitness apps (e.g., dietary apps and workout ...

    • The xTrans Transaction Model and FlexCP Commit Protocol 

      Arntsen, Anna-Brith (Research report; Forskningsrapport, 2006)
      Traditionally, transactions are flat and atomic possessing the ACID properties. The traditional ACID transaction model has clear limitations in new application domains where transactions often are long-running and require properties that go beyond ACID. Structuring a long-running transaction as an ACID transaction will impede both performance and concurrency. To meet extended and varying transactional ...

    • ZeroComm: Decentralized, Secure and Trustful Group Communication 

      Witharanage, Yasiru Rathsara (Mastergradsoppgave; Master thesis, 2023-05-15)
      In the context of computer networks, decentralization is a network architecture that distributes both workload and control of a system among a set of coequal participants. Applications based on such networks enhance trust involved in communication by eliminating the external author- ities with self-interests, including governments and tech companies. The decentralized model delegates the ownership ...

    • μPyCSP - Two approaches to implementing CSP-like concurrency modeling in microcontrollers. 

      Johansen, Jon Helge Langaas (Master thesis; Mastergradsoppgave, 2020-06-30)
      In this thesis, we have explored the possibility of bringing CSP-like concurrency modeling to an embedded environment. With the growth of IoT and embedded software, many of the hardships that come with concurrent coding in an inherently event-driven environment become more apparent. Convoluted and complex code is often used to handle the many fallacies of concurrency. We are solving this problem by ...
