      Salmi, Anna-Kaisa; Fjellström, Markus; Äikäs, Tiina; Spangen, Marte; Nunez, Milton; Lidén, Kerstin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-19)
      This paper presents new osteometric and stable isotope evidence of Sámi reindeer offerings. Previous archaeological studies have shown that reindeer domestication and intensification of reindeer herding transformed Sámi indigenous religion. However, because of the methodological challenges in the identification of wild and domesticated reindeer in the archaeological record, the exact nature of the ...
    • Blending functions based on trigonometric and polynomial approximations of the Fabius function 

      Olofsen, Hans (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      Most simple blending functions are polynomials, while more advanced blending functions are, for example, rational or expo-rational fractions. The Fabius function has the required properties of a blending function, but is a nowhere analytic function and cannot be calculated exactly everywhere on the required domain. We present a new set of trigonometric and polynomial blending functions with the shape ...
    • Finite element method application of ERBS triangles 

      Kravetc, Tatiana (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11)
      In this paper we solve an eigenvalue problem on a circular membrane with fixed outer boundary by using a finite element method, where an element is represented as an expo-rational blending triangle. ERBS triangles combine properties of B-spline finite elements and standard polynomial triangular elements. The overlapping of local triangles allows us to provide a flexible handling of the surface while ...
    • Football training specificity - Training individualization within the collective periodization 

      Baptista, Ivan (Doctoral thesis; Doktorgradsavhandling, 2020-02-04)
      Within the literature, different playing positions present different external load profiles in match-play and are associated with the individual variation in activity profiles. In contrast to detailed information regarding matches, few studies have focused on the training practices in football. Therefore, the aim of this thesis is to assess the levels of specificity that different playing-positions ...
    • Fangeleirer, kulturminnevern og arkeologi. Materielle erindringer fra Lyngenlinjen. 

      Figenschau, Ingar (Doctoral thesis; Doktorgradsavhandling, 2020-02-21)
      Denne avhandlingen tar utgangspunkt i Lyngenstillingen, en tysk forsvarslinje som ble bygget i løpet av høsten 1944 og vinteren 1945 i Storfjord, Troms fylke. Undersøkelsesområdet ligger i Norddalen, en forlengelse av Kitdalen som ligger innerst ved Lyngenfjorden. Her ligger restene etter tyske fangeleirer. Hovedfokuset for avhandlingen har vært å se nærmere på hvordan en arkeologisk vinkling på ...
    • When Russian is more Perfective than Spanish 

      Fábregas, Antonio; Janda, Laura Alexis (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      In this article we analyze cases in which Spanish imperfective aspect is equivalent to Russian perfective forms, a topic that has received very little attention in the literature. We argue that a crucial difference between perfectives in both languages is the relevance of the starting point of the event. Russian adopts an aspectual perspective from within an extended event, which gives access to the ...

      A growing body of research has pointed out effective leadership as an important influencing factor for safety performance in various high-risk industrial contexts. However, limited systematic knowledge is available about how leaders can effectively persuade rule compliance, and stimulate actions and participation. Recognizing effective means of influence is of value for safety leadership development ...
    • The Quotidian, Small and Incomplete: WWII and the Indifference of Things 

      Figenschau, Ingar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019)
      This article examines how things contribute to an expanded and different understanding of contexts that are usually reserved for historical inquiry. To show this, the article illustrates how archaeological investigations of World War II prison camps connected to the German defensive Lyngen Line in northern Norway have uncovered aspects that are absent or unavailable in historical sources. Accordingly, ...

Acore aspect of any SMC protocol is secure communication between participants.Based on the NOOP and SNOOP middleware with a combination of secret keyand public-key cryptography we design and implement a public key infrastruc-ture(PKI) to share signed ...
    • Simulating more realistic predation threat using attack playbacks 

      Watve, Mukta; Prati, Sebastian; Taborsky, Barbara (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-19)
      Use of virtual proxies of live animals are rapidly gaining ground in studies of animal behaviour. Such proxies help to reduce the number of live experimental animals needed to stimulate the behaviour of experimental individuals and to increase standardisation. However, using too simplistic proxies may fail to induce a desired effect and/or lead to quick habituation. For instance, in a predation ...
    • Consistent ice and open water classification combining historical synthetic aperture radar satellite images from ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1A/B 

      Johansson, Malin; Malnes, Eirik; Gerland, Sebastian; Cristea, Anca; Doulgeris, Anthony Paul; Divine, Dmitry V; Pavlova, Olga; Lauknes, Tom Rune (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-17)
      Synthetic Aperture Radar (SAR) satellite images are used to monitor Arctic sea ice, with systematic data records dating back to 1991. We propose a semi-supervised classification method that separates open water from sea ice and can utilise ERS-1/2, Envisat ASAR, RADARSAT-2 and Sentinel-1 SAR images. The classification combines automatic segmentation with a manual segment selection stage. The ...
