It has been developed a number of different ... -
Reconstructing Omni-kernel control flow
(Master thesis; Mastergradsoppgave, 2014-12-15)Today, with the prevalence of many- and multi-core systems has it been sparked a new interest for programming models that permits developer to exploit their resources. This has sparked renewed interest in creating larger event-based systems, systems where stack ripping occurs and with an obfuscated control flow. Both increases the complexity of debugging errors. During the development of the ... -

Ruoksat. A system for capturing, persisting and presenting the digital footprint of soccer knowledge and expertise
(Master thesis; Mastergradsoppgave, 2013-06-01)There are currently over 27 000 registered soccer teams in Norway. However, even with mandatory coaching licenses, there are still a vast variety of approaches to how training sessions should be planned and executed. Even in top-level professional soccer organizations, the planning of exercises involves a considerable amount of manual labor. The most common approaches include using old-fashioned pen ... -
Safe and secure outsourced computing with fully homomorphic encryption and trusted execution environments
(Master thesis; Mastergradsoppgave, 2020-06-30)Increases in data production and growing demands for more computing power leads to the current trend of outsourcing data and computation services to cloud providers. With data breaches and cases of data misuse becoming increasingly common, there is a high demand for secure systems. This, however, conflicts with the current data trust models. A solution to this that is becoming more common is the use ... -
Sáhka
(Mastergradsoppgave; Master thesis, 2022-05-25)Elite football today is infused with technologies for collecting data on players' performance and health. Technologies such as wearable health and fitness trackers, full-body medical scans, and positional systems mounted around a stadium give coaches a wide range of accurate data about their players. However, coaches do not have the time or ability to analyze all this data for each player to give ... -
Scalable exploration of population-scale drug consumption data
(Master thesis; Mastergradsoppgave, 2019-06-01)The potential for knowledge discovery is currently underutilized on pharmacoepidemiologic data sets. A big dataset enables finding and assessing rare drug consumption patterns that are associated with adverse drug reactions causing hospitalization, or death. To enable such exploration of big pharmacoepidemiology data, four key issues need so be addressed. First, to ingest, transform, preprocess ... -
A scalable, interactive widget library for visualizing biological data
(Master thesis; Mastergradsoppgave, 2011-06)In biology the introduction next generation technology is increasing the amount of data generated rapidly.
