Appendix E Telemedisinske løsninger i maritime operasjoner og redningstjeneste
(Research report; Forskningsrapport, 2016)Folk som jobber i maritime miljø har ikke enkel tilgang til sentrale helsetjenester, og det gjelder spesielt for sjøfolk som arbeider i arktiske områder. Selv om telemedisin har vært en suksess på land, har telemedisin kun i begrenset grad blitt tatt i bruk til havs. Dette skyldes blant annet fravær av gode kommunikasjonsløsninger, dårlige værforhold, store avstander og lange perioder utenfor ... -
Digital Chronofiles of Life Experience
(Chapter; Bokkapittel, 2015-02-28)Technology has brought us to the point where we are able to digitally sample life experience in rich multimedia detail, often referred to as lifelogging. In this paper we explore the potential of lifelogging for the digitisation and archiving of life experience into a longitudinal media archive for an individual. We motivate the historical archive potential for rich digital memories, enabling ... -
Data-intensive computing infrastructure systems for unmodified biological data analysis pipelines
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-18)Biological data analysis is typically implemented using a deep pipeline that combines a wide array of tools and databases. These pipelines must scale to very large datasets, and consequently require parallel and distributed computing. It is therefore important to choose a hardware platform and underlying data management and processing systems well suited for processing large datasets. There are many ... -
Kvik: three-tier data exploration tools for flexible analysis of genomic data in epidemiological studies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03-30)Kvik is an open-source system that we developed for explorative analysis of functional genomics data from large epidemiological studies. Creating such studies requires a significant amount of time and resources. It is therefore usual to reuse the data from one study for several research projects. Often each project requires implementing new analysis code, integration with specific knowledge bases, ... -
Description of spatio-temporal gait parameters in elderly people and their association with history of falls: Results of the population-based cross-sectional KORA-Age study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03-25)Background: In this epidemiological study we described the characteristics of spatio-temporal gait parameters among a representative, population-based sample of 890 community-dwelling people aged 65 to 90 years. In addition, we investigated the associations between certain gait parameters and a history of falls in study participants. <p>Methods: In descriptive analyses spatio-temporal gait parameters ... -
Towards Consent-Based Lifelogging in Sport Analytic
(Chapter; Bokkapittel, 2015)Lifelogging is becoming widely deployed outside the scope of solipsistic self quantification. In elite sport, the ability to utilize these digital footprints of athletes for sport analytic has already become a game changer. This raises privacy concerns regarding both the individual lifelogger and the bystanders inadvertently captured by increasingly ubiquitous sensing devices. This paper describes ... -
Fireflies: A Secure and Scalable Membership and Gossip Service
(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 ... -
DeltaTree: A Locality-aware Concurrent Search Tree
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-15)Like other fundamental abstractions for high-performance computing, search trees need to support both high concurrency and data locality. However, existing locality-aware search trees based on the van Emde Boas layout (vEB-based trees), poorly support concurrent (update) operations. We present DeltaTree, a practical locality-aware concurrent search tree that integrates both locality-optimization ... -

Freia: Exploring Biological Pathways Using Unity3D
(Master thesis; Mastergradsoppgave, 2015-11-15)To understand the biological processes related to the development of cancer there is a need for interactive data visualization tools that integrates experimental data with biological knowledge. Existing visualization tools have shown their usefulness, but next-generation biological data analysis requires both integrating different data types and larger datasets. This requires data exploration tools ... -
Evaluation of the power efficiency of UPC, OpenMP and MPI
(Research report; Forskningsrapport, 2015)In this study we compare the performance and power efficiency of Unified Parallel C (UPC), MPI and OpenMP by running a set of kernels from the NAS Benchmark. One of the goals of this study is to focus on the Partitioned Global Address Space (PGAS) model, in order to describe it and compare it to MPI and OpenMP. In particular we consider the power effi- ciency expressed in millions operations ... -
Investigating the security issues surrounding usage of Ephemeral data within Android environments
(Master thesis; Mastergradsoppgave, 2015-08-27)With mobile devices managing more and more of our personal data, for many it has become a ubiquitous resource. This is also true in the workplace where they are instituting Bring Your Own Device practices. While this saves the enterprise money in terms of equipment, it also increases the diversity of devices brought to work. This presents security problems as corporate data received and transmitted ... -
User-Based Information Search across Multiple Social Media
(Master thesis; Mastergradsoppgave, 2015-05-31)Most of todays Internet users are registered to one or more social media applications. As so many are registered to multiple application, it has become difficult to locate friends, former colleagues, peers and acquaintances. Reasons for this include private profiles, name collisions, multiple usernames, lack of profile attributes and profile picture. The system designed and implemented in this ... -

The project integrates together topics such as software system design and development, object-oriented programming, mobile application development, ... -
Improving Disk Performance in Vortex With NVMe
(Master thesis; Mastergradsoppgave, 2015-06-01)With the development of SSDs, performance limitations in persistent storage have shifted from the underlying medium to the interface through which the host and disk communicates. NVMe is a recently developed standard for operating SSDs connected to a host through PCI Express, and offers significant performance improvements compared to conventional interfaces, as well as features designed for ... -
Beyond the hospital walls - Extramural mobile communication with CallMeSmart
(Master thesis; Mastergradsoppgave, 2015-06-01)Physicians, nurses and other people who work at hospitals and in the healthcare sector often move around a lot. As they also frequently need to contact each other, mobile communication devices like pagers and wireless phones are important tools for letting them maintain contact. This can lead to problems as personnel are constantly interrupted during their work because coworkers don't know whether ... -
