Biodiversity on the line: life cycle impact assessment of power lines on birds and mammals in Norway
(Journal article; Peer reviewed, 2024)The global shift towards renewable energy plays an important role in fighting climate change. To facilitate the global growth of renewable energy production, the expansion of the electric grid becomes inevitable. Yet further ... -
Mathematical sciences as symbolic form: the objects and objectivity of science in Ernst Cassirer’s philosophy of science and culture
(Journal article; Peer reviewed, 2024)In this paper, I explore how Cassirer’s early and mature epistemology, philosophy of science, and philosophy of culture make up a coherent and comprehensive view of the mathematical sciences that is fruitful for understanding ... -
Manufacturing techniques for improved rate capacity of thick electrodes by tailored electrode structures
(Journal article; Peer reviewed, 2025)Increasing the specific energy of Lithium-ion batteries (LIBs), has been improved by increasing the portion of active mass and pre-lithiation. The former consists of both increasing the cell size and electrode layer ... -
Investigating the influence of the modeling depth on the design optimization of heat pumps for local heat generation
(Master thesis, 2025)Varmepumper har blitt identifisert som en nøkkelteknologi for overgangen fra dagens fossile varmeforsyning til en utslippsfri varmeforsyning. I motsetning til forbrenningsbaserte varmegeneratorer, avhenger egenskapene til ... -
