Increased traffic and interest in arctic regions necessitate measures to ensure the safety and functionality of vessels. Sea-spray icing is one of the significant hazards for small- and medium-sized vessels in polar waters. Ice cover can restrict access to essential parts of a vessel and compromise its stability. Existing deicing measures, such as heat or chemical application and manual ice removal, ...

In response to the increasing demand for construction informatics (CI) expertise, universities in the Nordic countries have developed new educational offers. This study explores how CI related education is being delivered by three different universities, two in Norway and one in Sweden. By comparing curricula and interviewing CI teachers, this paper contributes to the recent debate on the international ...

The microbial fuel cell (MFC) technology is emerging as an effective technology for wastewater treatment to remove and detect many pollutants and simultaneously generate power. The anode is an essential component for bacterial attachment and extracellular electron transfer (EET). Thus, anode performance is critical for improving an MFC system's overall performance. Materials that are electronically ...

According to a new high-rise strategy, Norway is expected to have more tall buildings. However, due to a lack of knowledge and experience in high-rise technology, the country has not built many such structures yet. To address this issue, a study was conducted to analyze the response of a high-rise building to dynamic wind load, considering the low seismic activity in the region. The study is divided ...

Denne oppgaven har utforsket konseptet om å bygge en klimaskjerm rundt Jernvassdammen i Nord-Norge, med integrerte solcellepaneler som en del av skjermen. Motivasjonene bak dette konseptet er å skape en «vinn-vinn situasjon» der både dammens fysiske integritet og bærekraftige energiproduksjon blir fremmet. Oppgaven har evaluert tilstanden til Jernvassdammen og funnet at selv om betongkonstruksjonen ...

Effektiv bruk energi i et hus/bygg er en drivende utvikling i byggenæring i de siste år. Det er en komplisert-omfang-og sammensatt problem for byggteknologi. For nevnt noe problemstiller, hvordan/hvilken energi kilde som elektrisk, fjernvarme, sol-, vind- som dekker huse behov og samt ha en gunstig effekt på natur, kostnad, og samfunnsforhold. Og, hvordan får vi optimal/gunstig fordeling energi i ...

Denne masteroppgaven er en litteraturstudie av luftfuktighet i bolighus, i tillegg til en case studie i bolighus knyttet til luftfuktighet ved planter. Oppgaven dekker litteraturstudie knyttet til forskning og fakta både i Norge og internasjonalt. Ifølge verdens helseorganisasjon (WHO) oppholder en person seg 90 % av tiden innendørs. Luftfuktighet er en av faktorene som er avgjørende for at inneklima ...

As the demand for concrete increases to meet the expanding need, the environmental impact of its production cannot be ignored. The use of ordinary Portland cement (OPC) is known to deplete natural resources and release large amounts of CO2 into the atmosphere. Geopolymer concrete (GPC), made from waste and industrial by-products, has shown the potential to overcome the environmental issues associated ...

Society recognises the need for the preservation of nature and the need for better resource utilisation. Integration of good practice in the building industry is mainly targeted at reducing or completely eliminating waste. One of the waste sources in the concrete industry is created in washing facilities and consists of returned concrete, washing water and cement slurry. Concrete trucks are washed ...
