Enabling Two-Way Communication of Deaf Using Saudi Sign Language
(Peer reviewed; Journal article, 2023)Disabled people are facing many difficulties communicating with others and involving in society. Modern societies have dedicated significant efforts to promote the integration of disabled individuals into their societies ... -
Hygrothermal Modeling of Masonry with Interior Insulation Retrofit - Perspectives on hygrothermal performance and modeling-uncertainty
(Doctoral theses at NTNU;2024:43, Doctoral thesis, 2024)Energy retrofit of existing buildings is mainly an endeavor to reduce energy consumption. Interior insulation retrofit of masonry falls among retrofit measures in this regard. However, interior insulation of masonry may ... -
NTNU-SINTEF SolarNet: A solar irradiation monitoring network at high latitudes
(Peer reviewed; Journal article, 2023)This study presents a monitoring network for solar irradiation at high latitudes, called NTNU-SINTEF SolarNet. The network collects, with a time resolution ranging from seconds to hours, solar irradiance data, e.g. global ... -
Validation of decomposition models for solar irradiance at high latitudes: A preliminary study
(Peer reviewed; Journal article, 2023)The accurate estimation of buildings' solar potential contributes to boost the exploitation of solar energy at high latitudes. The decomposition of global irradiation into the direct and diffuse fractions is a fundamental ... -
Enhanced permafrost creep model– user manual and documentation
(Research report, 2016)The mechanical behavior of frozen soils is one of the challenging topics in the field of geotechnical engineering. The behavior of frozen soils is strongly affected by the amount of ice, while on the other hand, the amount ... -

Watertight insertion of heavy sliding doors in exterior walls
(Peer reviewed; Journal article, 2023)The joints around heavy terrace doors are considered a weak point in rain-exposed façades, as it is vulnerable to defects in design and construction. The insertion process of heavy sliding doors is a notable challenge. ... -
A General and Effective Method for Wall and Protrusion Separation from Facade Point Clouds
(Peer reviewed; Journal article, 2023)As a critical prerequisite for semantic facade reconstruction, accurately separating wall and protrusion points from facade point clouds is required. The performance of traditional separation methods is severely limited ... -
Strength Development of Metakaolin-Based Alkali-Activated Cement
(Peer reviewed; Journal article, 2023)Alkali-activated materials, sometimes called geopolymers, can be used as alternative cementitious materials to conventional Portland cement. Currently, there is a significant interest in these materials due to their low ... -
Report on Field Investigation and Long-Term Plate Loading test in Permafrost
(Research report, 2023)This report presents a comprehensive overview of field investigations and large-scale plate loading tests conducted at the UNIS East site in Longyearbyen from March 2020 to July 2023. These tests were undertaken as part ... -
Modelling mesh independent failure loads of a soft strain-softening clay using a rate dependent model
(Peer reviewed; Journal article, 2023)If no regularisation method is used during finite element modelling of strain-softening (brittle) materials, results become mesh dependent: manifesting as very thin shear bands whose thickness and orientation depends on ... -
Report on calibrated and validated numerical models to estimate site specific stability of coastal infrastructure in a changing climate with thawing permafrost
(Research report, 2022)This report presents an overview of the costal erosion model and the infrastructure stability model that are capable of predicting the site-specific response to the global warming and thawing permafrost. The models are ... -
Investigating strength development over time of industrial by-products using the resonance column free-free technique
(Peer reviewed; Journal article, 2023)Soil improvement using cementitious binders is used throughout the world to improve the strength and stiffness characteristics of soft soils. Strength verification is typically performed using unconfined compression tests; ... -
Strategies for Legionella Management in Drinking Water Systems: An Examination of Water intake Location or Placement and Flushing Efficacy
(Doctoral theses at NTNU;2023:440, Doctoral thesis, 2023)Legionella, particularly Legionella pneumophila, are opportunistic bacteria found in artificial and natural aquatic environments that may cause severe pneumonia, known as Legionnaires’ disease, and mild influenza-like ... -
Hydrologic performance modelling of green roofs using conceptual and data-driven modelling tools
(Doctoral theses at NTNU;2023:425, Doctoral thesis, 2023)With climate change and rapid urbanization, the amount and intensity of stormwater flow are expected to increase, leading to frequent failures and overflows of conventional stormwater infrastructures. To address this issue, ... -

Fire spread in a large compartment with exposed cross-laminated timber and open ventilation conditions: #FRIC-02 - Exposed wall and ceiling
(Journal article; Peer reviewed, 2023)Cross-laminated timber (CLT) is becoming increasingly popular due to its many advantages. However, it has been shown that exposed CLT can have a significant effect on fire dynamics and spread rates. Further studies are ... -
Detecting vertices of building roofs from ALS point cloud data
(Peer reviewed; Journal article, 2023)Roof vertex information is vital for 3D roof structures. Reconstructing 3D roof structures from point cloud data using traditional methods remains a challenge because their extracted roof vertices are affected by uncertainty ... -
Behaviour of 60-year-old trial embankments on peat
(Peer reviewed; Journal article, 2023)The search for low cost solutions for roads on peatlands inspired the construction of four full scale trial embankments at two sites in Norway in the early 1960's. The embankments are still accessible and this work was ...
