<p>Accurate forest monitoring is crucial as forests are major global carbon sinks. Additionally, accurate prediction of forest parameters, such as forest biomass and stem volume (SV), has economic importance. Therefore, the development of regression models for forest parameter retrieval is essential. <p>Existing forest parameter estimation methods use regression models that establish pixel-wise ...

The topic covered in this thesis is medical temperature measurement of subcutaneous parts of human tissue with use of microwave radiometry. Radiometry is a completely non-invasive, non-toxic and relatively inexpensive sensing modality. The radiometric technique is based on the measurement of electromagnetic noise power emitted by lossy materials. The method has explicit low investment costs and ...

Over the course of the last three decades, Synthetic Aperture Radar (SAR) has proven itself to be an effective monitoring technology for marine applications. The clear benefits of using SAR as opposed to optical devices is that SAR is insensitive to cloud cover, lighting conditions and can also provide imagery to a high degree of resolution. Given these benefits, there is a large incentive to implement ...

In this study we have explored the structure activity relationship of molecules with potential as novel drug classes toward current medical challenges as hypertension, cancer and infections caused by antibiotic resistant bacteria. Direct renin inhibitors have for a long time been an interesting group of potential anti-hypertension drugs, as they inhibit the first and rate-limiting step in the signal ...

The main focus of this thesis is the diagnostics of ion beams in helicon plasma devices with expanding magnetic field, and running in an inductive mode. These ion beams are closely connected to the concept of current-free double layers (CFDL). We started by investigating how to best interpret the measurements from a Retarding Field Energy Analyzer (RFEA) through 3-dimensional particle-in-cell ...

We compute differential invariants for several Lie pseudogroups, and use them for solving the equivalence and classification problem for a variety of mathematical structures appearing in geometry and mathematical physics. We demonstrate utility of the algebra of rational scalar differential invariants for solving these two problems, also in cases where the structures are given as solutions to a ...

The work summarized in this thesis has its basis in technology to support human collaboration. I have investigated how large, high-resolution display (LaHiRD) technology, implemented using display wall technology (large, tiled displays implemented as one coherent display surface) could support clinical work. Hence, I have worked with the topic of technological support for human collaboration (or ...

This dissertation presents MultiStage, a human-to-human interaction system meant to be use by actors on a stage to interact and perform with actors on other stages as if they were on the same stage. MultiStage includes several local side stages and a global side. It uses a publish-subscribe model to handle the handover of data streams. Local side produces data streams about actors to global side. ...

Arktis er en av de få gjenværende, geologisk minst undersøkte, områdene i verden, hvor den norske kontinentalmarginen i Barentshavet nå blir undersøkt og har både vitenskapelig og industriell interesse. Formålet med doktorgradsavhandlingen er å få en bedre forståelse av interne og eksterne karakteristikker, utbredelse i rom og tid, sedimentasjonsmiljø og deformasjonsgrad av kenozoiske dypmarine ...

United Nations' Sustainable Development Goal 14 aims to conserve and sustainably use the oceans and their resources for the benefit of people and the planet. This includes protecting marine ecosystems, preventing pollution, and overfishing, and increasing scientific understanding of the oceans. Achieving this goal will help ensure the health and well-being of marine life and the millions of people ...
