    • Appendix E Telemedisinske løsninger i maritime operasjoner og redningstjeneste 

      Woldaregay, Ashenafi Zebene; Hartvigsen, Gunnar; Walderhaug, Ståle (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 

      Gurrin, Cathal; Johansen, Håvard; Sødring, Thomas; Johansen, Dag (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 

      Bongo, Lars Ailo; Pedersen, Edvard; Ernstsen, Martin (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 

      Fjukstad, Bjørn; Olsen, Karina Standahl; Jareid, Mie; Lund, Eiliv; Bongo, Lars Ailo (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 

      Thaler-Kall, Kathrin; Peters, Annette; Thorand, Barbara; Grill, Eva; Autenrieth, Christine S.; Horsch, Alexander; Meisinger, Christa (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 

      Johansen, Håvard; Gurrin, Cathal Gerard; Johansen, Dag (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 

      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 ...
    • DeltaTree: A Locality-aware Concurrent Search Tree 

      Umar, Ibrahim; Anshus, Otto; Ha, Hoai Phuong (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 ...
    • Naturvitenskapens grunnlag og begrensning. Seminarrapport 

      Thorvaldsen, Steinar (Research report; Forskningsrapport, 1979)
      Foredrag av Arthur E. Wilder-Smith og Udo Middelmann holdt ved NTH i 1979
    • Evaluation of the power efficiency of UPC, OpenMP and MPI 

      Lagraviere, Jeremie; Ha, Hoai Phuong; Cai, Xing (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 ...

    • A Low-Intensity Mobile Health Intervention With and Without Health Counseling for Persons With Type 2 Diabetes, Part 1: Baseline and Short-Term Results From a Randomized Controlled Trial in the Norwegian Part of RENEWING HEALTH 

      Torbjørnsen, Astrid; Jenum, Anne Karen; Småstuen, Milada Cvancarova; Årsand, Eirik; Holmen, Heidi; Wahl, Astrid Klopstad; Ribu, Lis (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12-11)
    • Transparent Incremental Updates for Genomics Data Analysis Pipelines 

      Pedersen, Edvard; Willassen, Nils Peder; Bongo, Lars Ailo (Chapter; Bokkapittel, 2014)
      A large up-to-date compendium of integrated genomic data is often required for biological data analysis. The compendium can be tens of terabytes in size, and must often be frequently updated with new experimental or meta-data. Manual compendium update is cumbersome, requires a lot of unnecessary computation, and it may result in errors or inconsistencies in the compendium. We propose a transparent ...
    • Mr. Clean: A Tool for Tracking and Comparing the Lineage of Scientific Visualization Code 

      Tartari, Giacomo; Tiede, Lars; Holsbø, Einar; Knudsen, Kenneth; Raknes, Inge Alexander; Fjukstad, Bjørn; Mode, Nicolle; Bjørndalen, John Markus; Lund, Eiliv; Bongo, Lars Ailo (Conference object; Konferansebidrag, 2014)
    • An Evaluation Framework for Defining the Contributions of Telestration in Surgical Telementoring 

      Budrionis, Andrius; Augestad, Knut Magne; Patel, Hitendra R.H.; Bellika, Johan Gustav (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Background: An increasing quantity of research in the domain of telemedicine show a growing popularity and acceptance of care over distance systems among both clinicians and patients. We focus on telementoring solutions, developed for providing remote guidance to less experienced surgeons. Telestration is often regarded as an extra functionality of some telementoring systems. However, we advocate ...
