Direction Following Control of Planar Snake Robots Using Virtual Holonomic Constraints
(Journal article; Peer reviewed, 2015)This paper investigates the problem of direction following for planar snake robots. The control objective is to regulate the linear velocity vector of the snake robot to a constant reference while guaranteeing boundedness ... -
The Direction of Updatable Encryption Does Not Matter Much
(Peer reviewed; Journal article, 2020)Updatable encryption schemes allow for key rotation on ciphertexts. A client outsourcing storage of encrypted data to a cloud server can change its encryption key. The cloud server can update the stored ciphertexts to the ... -
Direction- and Angle-Assisted Buttonhole Cannulation of Arteriovenous Fistula in Hemodialysis Patients: A Multicenter Randomized Controlled Trial
(Peer reviewed; Journal article, 2022)Rationale & objective: Arteriovenous fistula cannulation with the buttonhole technique is often preferred by patients but has been associated with an increased infection risk. Guidelines disagree on whether it should be ... -
Directional fatigue behaviour of maraging steel grade 300 produced by laser powder bed fusion
(Peer reviewed; Journal article, 2021)Surfaces of metals produced by additive manufacturing (AM) are known to be rough and populated with defects, this is, in particular, true for downward-facing (down-skin) surfaces. When dealing with the fatigue of as-built ... -
Directional turnover towards larger-ranged plants over time and across habitats
(Peer reviewed; Journal article, 2021)Species turnover is ubiquitous. However, it remains unknown whether certain types of species are consistently gained or lost across different habitats. Here, we analysed the trajectories of 1827 plant species over time ... -
Directional wave spectrum estimation with ship motion responses using adversarial networks
(Peer reviewed; Journal article, 2022)The external environmental conditions around a vessel are essential for efficient and safe ship operation, among which the sea state is of key importance. Considering the ship as a large wave buoy, the sea state can be ... -
Directionality and column arrangement principles of precipitates in Al-Mg-Si-(Cu) and Al-Mg-Cu linked to line defect in Al
(Journal article, 2016)In the structures of all metastable precipitates in Al-Mg-Cu and Al-Mg-Si alloys, we find that column surrounding of an element column in the needle/lath direction order according to simple principles. Advanced transmission ... -
Directions for Research on Climate and Conflict
(Peer reviewed; Journal article, 2020)The potential links between climate and conflict are well studied, yet disagreement about the specific mechanisms and their significance for societies persists. Here, we build on assessment of the relationship between ... -
Dirichlet-to-Neumann maps, abstract Weyl–Titchmarsh M-functions, and a generalized index of unbounded meromorphic operator-valued functions
(Journal article; Peer reviewed, 2016)We introduce a generalized index for certain meromorphic, unbounded, operator-valued functions. The class of functions is chosen such that energy parameter dependent Dirichlet-to-Neumann maps associated to uniformly elliptic ... -
Disability leisure: in what kind of activities, and when and how do youths with intellectual disabilities participate?
(Journal article; Peer reviewed, 2016)The article examines what kind of activities youths with intellectual disabilities participate in during their leisure time, and when and how they participate. The analysis is based on qualitative interviews of 10 youths ... -
Disability measurements: impact on research results
(Journal article; Peer reviewed, 2012)This article addresses the issue of whether the choice of operational definition of disability in survey research affects findings. Earlier studies have shown that different definitions cause substantial variation in ... -
Disability pension and symptoms of anxiety and depression: a prospective comparison of farmers and other occupational groups. The HUNT Study, Norway.
(Journal article; Peer reviewed, 2015)Objectives: Agriculture has undergone major changes, and farmers have been found to have a high prevalence of depression symptoms. We investigated the risk of work disability in Norwegian farmers compared with other ... -

(Peer reviewed; Journal article, 2023)Disabled students encounter complex barriers to participation and inclusion throughout higher education and face challenges transitioning into employment. This study has engaged eight disabled university students in ... -
Disagreement in metametaphysical dispute
(Peer reviewed; Journal article, 2022)Recent years have seen several studies of metaphysical disputes as disagreement phenomena employing the resources from the research on disagreement in social epistemology. This paper undertakes an analogous study of the ... -
Disam: Density Independent and Scale Aware Model for Crowd Counting and Localization
(Journal article; Peer reviewed, 2019)People counting in high density crowds is emerging as a new frontier in crowd video surveillance. Crowd counting in high density crowds encounters many challenges, such as severe occlusions, few pixels per head, and large ... -
Disappearance of eggs from non-parasitized nests of brood parasite hosts – the evolutionary equilibrium hypothesis revisited
(Journal article; Peer reviewed, 2016)The evolutionary equilibrium hypothesis was proposed to explain variation in egg rejection rates among individual hosts (intra- and interspecific) of avian brood parasites. Hosts may sometimes mistakenly reject own eggs ... -
