Parameter estimation for the weibull general log-linear model in accelerated life testing
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025)Uncertainty is commonly present in accelerated life test (ALT) data. The combination of a general log-linear model with a statistical distribution model—using the Weibull distribution in this paper—allows for addressing both multiple operational factors and uncertainty within a single model. This paper interprets the Weibull General Log-Linear (WGLL) model from the ALT perspective. Two parameter ... -

Role of Onshore Operation Centre and Operator in Remote Controlled Autonomous Vessels Operation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024)The need for more skilled human resources and higher operational costs in conventional shipping will create the need for autonomous shipping. To make autonomous shipping a reality, the shipping industry will require building supportive infrastructure and facilities to ensure the safe operations of future autonomous vessels. To provide necessary support functions in autonomous vessel operations is ... -
Site specific avalanche warning for settlements in Northern Norway: Twenty years of the Northern Norway Avalanche Surveillance Program
(Journal article; Tidsskriftartikkel; Peer reviewed, 2024-09)Northern Norway experienced an intensely snow rich winter in 1997 when settled snow heights reached a record 240 cm at the weather station in Tromsø on April 29th. Numerous avalanches, settlement evacuations, and two fatalities in a destroyed house in the settlement of Breivikeidet left the public exhausted at the end of the winter. The chaotic response to avalanche events during the season demonstrated ... -
A sustainable way to prevent oral diseases caused by heavy metals with phytoremediation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2025-01-19)Sustainability, food security, and human health. This study builds on previous research [1] and explores the role of phytoremediation, a plant-based, eco-friendly strategy in mitigating heavy metal pollution to achieve Sus tainable Development Goal 3 (Good Health and Well-being) while addressing its lesser-known implications for oral and dental health. Through an analysis of seven key metals ... -
