Weighted Hardy-Type Inequalities in Variable Exponent Morrey-Type Spaces
(Peer reviewed; Journal article, 2013) -
Weighted Hardy Operators in Complementary Morrey Spaces
(Peer reviewed; Journal article, 2012)We study the weighted -boundedness of the multidimensional weighted Hardy-type operators and with radial type weight , in the generalized complementary Morrey spaces defined by an almost increasing function . We prove a ... -
Ice conditions in northern Norwegian fjords: Observations and measurements from three winter seasons, 2017–2020
(Peer reviewed; Journal article, 2022)Freshwater provided by rivers beginning deep within the mountains, feeds into fjords along the coast of Norway, often forming a brackish surface layer that will change in its salinity, thickness, and extent throughout the ... -

Large-scale shear test of brash ice
(Peer reviewed; Journal article, 2022)A large-scale shear apparatus has been originally developed and built to test the mechanical properties of coarsegrained material. It was used to evaluate the shear behaviour of brash ice. The brash ice blocks were collected ... -
Generalized Chessboard Structures Whose Effective Conductivities Are Integer Valued
(Journal article; Peer reviewed, 2012)We consider generalized chessboard structures where the local conductivity takes two values 𝑎� and 𝑏�. All integer combinations of 𝑎� and 𝑏� which make the components of effective conductivity matrix integer valued are ... -
Assessment of Hydrocarbon Degradation Potential in Microbial Communities in Arctic Sea Ice
(Peer reviewed; Journal article, 2022)The anthropogenic release of oil hydrocarbons into the cold marine environment is an increasing concern due to the elevated usage of sea routes and the exploration of new oil drilling sites in Arctic areas. The aim of this ... -
A Comprehensive Summary of Available Legislation and Practices in Demolition and Construction & Demolition Waste Management in the Arctic Region
(Peer reviewed; Journal article, 2021)The need for better natural resource use is currently increasingly recognised, and high emphasis is given to the circularity of building materials and the reduction of activities with negative environmental impact. ... -
Microstructure evolution of young sea ice from a Svalbard fjord using micro-CT analysis
(Peer reviewed; Journal article, 2021)We analysed the three-dimensional microstructure of sea ice by means of X-ray-micro computed tomography. Microscopic (brine- and air- pore sizes, numbers and connectivity) and macroscopic (salinity, density, porosity) ... -
Freeze-thaw damage evaluation and model creation for concrete exposed to freeze–thaw cycles at early-age
(Peer reviewed; Journal article, 2021)Concrete subjected to freeze–thaw cycles action at early-age will suffer serious physical damage, resulting in degradation of the concrete’s performance. The subsequent curing conditions after early-age freeze–thaw cycles ... -
Mechanical and durability properties of concrete subjected to early-age freeze–thaw cycles
(Peer reviewed; Journal article, 2021)Early-age frost damage to concrete used in winter construction or in cold environments negatively affects the development of the hydration process and the performance of the concrete, thereby reducing the service life of ... -
Microbial Community Dynamics during Biodegradation of Crude Oil and Its Response to Biostimulation in Svalbard Seawater at Low Temperature
(Peer reviewed; Journal article, 2021)The development of oil exploration activities and an increase in shipping in Arctic areas have increased the risk of oil spills in this cold marine environment. The objective of this experimental study was to assess the ... -
Low-temperature (-10 °C) curing of Portland cement paste – synergetic effects of 1 chloride-free antifreeze admixture C-S-H seeds, and room-temperature pre-curing
(Peer reviewed; Journal article, 2021)Cold weather drastically shortens the construction season in northern regions. Low ambient temperatures are known to have detrimental impacts on the reactivity and hardened performance of cementitious materials. This study ... -
Influence of concrete’s mechanical properties on the cracking of concrete dams
(Chapter, 2021)Analytical methods of structural stability assessment of concrete dams are often too simple and thus conservative in their predictions.Without the actual foundation geometry, capacity for some rigid body failure modes are ... -
Ice load measurements on Rätan concrete dam using different sensor types
(Peer reviewed; Journal article, 2021)Concrete dams in cold regions are designed to withstand loads from the ice sheet on top of the reservoir.However, the ice load's magnitude and return period are among the most considerable uncertainties in safety assessments ... -
Post-peak behavior of concrete dams based on nonlinear finite element analyses
(Peer reviewed; Journal article, 2021)Dam failures are catastrophic events and in order to improve safety, engineers must have good tools for analysis and an understanding of the failure process. Since there are few cases of real failures in concrete dams, ... -

Influence of large-scale asperities on the shear strength of concrete-rock interface of small buttress dams
(Peer reviewed; Journal article, 2021)This paper presents an investigation of the influence of large-scale asperities on the shear strength of four physical models of a pillar (also known as buttress web)from Kalhovd dam in Norway. The objective was to observe ... -
Workflow for Off-Site Bridge Inspection Using Automatic Damage Detection-Case Study of the Pahtajokk Bridge
(Peer reviewed; Journal article, 2021)For the inspection of structures, particularly bridges, it is becoming common to replace humans with autonomous systems that use unmanned aerial vehicles (UAV). In this paper, a framework for autonomous bridge inspection ... -
Influence of location of large-scale asperity on shear strength of concrete-rock interface under eccentric load
(Journal article, 2020)The location and geometry of large-scale asperity present at the foundation of concrete gravity dams and buttress dams affect the shear resistance of the concrete-rock interface. However, the parameters describing the ...
