Trend effects on perceived avalanche hazard
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-30)Hazard-level forecasts constitute an important risk mitigation tool to reduce loss of economic values and human life. Avalanche forecasts represent an example of this. As for many other domains, avalanche risk is communicated using a color-coded, categorical risk scale aimed at informing the public about past, current, and future risk. We report the results from three experiments in which we ... -

Origin and Development of Seamanship Competence
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06)Seafaring is one of the oldest documented human activities, with a rich heritage created by generations of seamen. The first boats were developed several thousand years ago, based on primitive principles, and they were probably not suitable for other than simple purposes. Analyzing the history of boat building shows a gradual change in designs. These design changes were most likely due to improvements, ... -
Reliability modelling on two-dimensional life data using bivariate weibull distribution: with case study of truck in mines
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)An engineering system can exhibit two- or multi-dimensions in its lifetime. As the classical univariate distribution cannot model this multi-dimensional characteristic, it is necessary to extend it to multivariate distribution in order to capture the multi-dimensional characteristics. This paper proposes a bivariate Weibull distribution that combines two classical Weibull models by a common exponent. ... -
Determinants, methods, and solutions of evacuation models for passenger ships: A systematic literature review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-02)Passenger ships facilitate the mobility of people at sea and are a significant revenue stream for societies. Simultaneously, they should meet safety standards. One of the main safety pillars is offering passengers a reliable emergency evacuation plan. The International Maritime Organization (IMO) has disseminated guidelines for passenger ships to enhance the evacuation process understanding. Although ... -
Cluster-based ensemble learning for wind power modeling from meteorological wind data

A rather wild imagination: who is and who is not a migrant in the Czech media and society?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-06)This paper focuses on migrants and migration in the context of the Czech Republic, an ethnically and nationally homogeneous country without significant migration experience. Despite this fact, the issue of migration became very prominent in 2015 and has been an integral part of Czech political and public discourse since then. Although the topic has attracted scholarly interest, but the reflection ... -
Machine learning forecasts of Scandinavian numerical weather prediction wind model residuals with control theory for wind energy
