This thesis report explores the critical challenge of water flooding in conveyor belt systems within the iron ore mining sector, with a focus on LKAB, a leading Swedish mining company. The study begins by outlining the significance of addressing water accumulation issues that compromise operational efficiency and safety in mining environments. Through an extensive literature review, the research ...

This thesis goes through the product development process for a shoulder joint meant for a future patient simulator. The process focuses on the methodology taught during the masters’ degree for how an idea can be developed into a product.

This thesis explores the innovative use of unmanned aerial vehicles to conduct draft surveys of large maritime vessels. This process is critical for determining vessel load through water displacement measurements. At the port of Narvik, a crew typically performs this task manually, where LKAB’s iron ore cargo vessels are surveyed while docked. The usual method requires going around the ship in ...

This thesis assesses the impact of fine-tuning and rag on llms in accurately assigning icd-10 codes to historical causes of death. Using funeral records from Trondheim, Norway (1830-1920), we fine-tuned Llama 3 and Mistral on 2000 records. Twelve experiments were conducted on 2000 additional records to evaluate the accuracy of each knowledge-injection technique, as well as a combination of the ...

Som fersk prosjektleder hos entreprenør, ble det feilbestilt åtte innerdører som hadde for lavt lydreduksjonstall i forhold til kravet. Dørene hadde spesiell størrelse og farge, tilpasset prosjekt, og ingen ville ha dem gratis. De ble kastet på søpla og generte nærmere ett tonn avfall. Slike feilbestillinger representerer en stor del av avfallet fra norske byggeplasser. Verdens samlede forbruk ...

3D-printing of polymers come in a large variety of methods and materials, each configuration with its own strengths and weaknesses. To compute and estimate mechanical properties of 3D-printed parts, good knowledge to the geometry of the internal structures is important to obtain. This will vary between different printers and slicers. As 3D-printed parts are anisotropic, it is often challenging to ...

Thanks to technical improvements, drones may now perform more than simply visual inspections of structures and buildings. An Unmanned Aerial Vehicle (UAV) drone can be equipped with a robotic arm or an attachment with sensors to check and test the structures and buildings. Designing a robotic arm with a modular end-effector that can be attached to a drone was the focus of this master's thesis research. ...

Slam er restproduktet ved rensing av avløpsvann og i produksjon av oppdretts- og settefisk, og lar seg fjerne fra vannet gjennom sedimentering, flotasjon og/eller filtrering. I kraft av sitt rike innhold av organisk materiale og næringsstoffer, er slam samtidig en verdifull ressurs. Avhengig av dets råstoffsammensetning, kan slammet blant annet benyttes i produksjon av biogass, og følgelig inngå som ...

Background: Z-hypnotics or z-drugs are commonly prescribed for insomnia and sleep difficulties in older adults. These drugs are associated with adverse events and dependence and are not recommended for long-term use. Despite evidence of older adults being more sensitive to a wide array of adverse events and clinical guidelines advocating limiting use, inappropriate use in this population is still ...

The ASEAN region has among the highest concentrations of plastic litter globally. The knowledge on microplastic pollution in that region is still limited and needs further investigation for policy implementation. To support the implementation of the Regional Action Plan for combatting marine debris, the proposed Regional ASEAN Baseline Study on Microplastics is intended as a summary report that ...
