Municipalities have an important role in crisis management. The Norwegian emergency principles of responsibility, parity and proximity are central, and the government expects municipalities to take care of crises in their area in accordance with the civil protection law. Due to the varying natures of different crises, one can expect crisis management to take different paths. This paper challenges ...

To meet the availability target and reduce system downtime, effective maintenance have a great importance. However, maintenance performance is greatly affected in complex ways by human factors. Hence, to have an effective maintenance operation, these factors needs to be assessed and quantified. To avoid the inadequacies of traditional human error assessment (HEA) approaches, the application of ...

Environmental data exhibits as huge amount and complex dependency. Utilizing these data to detect anomaly is beneficial to the disaster prevention. Big data approach using the machine learning method has the advantage not requiring the geophysical and geochemical knowledge to detect anomaly. This paper using the popular support vector regression (SVR ) to model the correlation between factors. ...

A series of column leaching experiments were performed to understand the leaching behavior of Co, Fe and Ni in Ballangen mine tailings. Multivariate statistical approaches to evaluate potential risk variations in leachate quality and identifies temperature effects on their leaching behavior. Results from column leaching test indicated that the mobility of showed higher temperature may encourage ...

This study aimed to assess how the current climate change perspective, with various air temperature (4°C, 10°C, 14°C and 18°C) affected metal releasing from tailings. Heavy metals pollution from tailings leaching are of increasing concern. Column leaching experiment was conducted for 15 weeks to a series of tailings with 20 mm/week water leaching four temperature situations. Leachate chemical physics ...

A risk analysis should provide decision makers with information regarding relevant hazards. The initiating phase, where the risk analysts identify hazards to be included in the risk analysis, lays the foundation for the rest of the analysis. This phase is, therefore, of great importance. In this paper, we examine how risk analysts in a municipal setting identified potential adverse events and how ...

In the maritime industry, it is of vital importance that personnel onboard ships are familiarized with the ship’s layout, along with safety equipment and processes for safeguarding of the individual seafarer and the ship’s crew. In fact, international maritime regulations require that all personnel employed or engaged on a seagoing ship receive proper familiarization training. However, several studies ...

Modern vessels are designed to collect, store and communicate large quantities of ship performance and navigation information through complex onboard data handling processes. That data should be transferred to shore based data centers for further analysis and storage. However, the associated transfer cost in large-scale data sets is a major challenge for the shipping industry, today. The same cost ...

I denne artikkelen undersøker vi om regionale innovasjonsnettverksorganisasjoner (RINOer) bidrar til bedre kunnskapstilgang og innovasjon. Hvilke organiserte aktiviteter eller funksjoner i RINOen er i så fall relevante? Og i hvilken grad påvirker andre kjennetegn ved RINOene eller bedriftene som deltar, et slikt utfall? Bedriftene i studien rapporterer at RINO-deltakelsen har bidratt positivt både ...

Statistical Data analysis and visualization approaches to identify ship speed power performance under relative wind (i.e. apparent wind) profiles are considered in this study. Ship performance and navigation data of a selected vessel are analyzed, where various data anomalies, i.e. sensor related erroneous data conditions, are identified. Those erroneous data conditions are investigated and several ...
