Investigations of surface loads of the Earth - geometrical deformations and gravity changes
(PhD Thesis;2009:25, Doctoral thesis, 2009)This thesis addresses deformations and gravity changes due to surface loads like the ocean tides, hydrology and glaciers. These phenomena are discussed in light of height and gravity observations collected by GPS and ... -
Kostnadseffektiv håndtering av overvann og urban flom i en by i vekst og i et klima i endring
(PhD thesis;2022:24, Doctoral thesis, 2022)Utfordringer knyttet til overvann og urban flom som følge av klimaendringer og fortetting er og vil være et viktig tema i årene fremover. Tradisjonelt transporteres overvann i lukkede overvanns- og avløpssystemer som ... -
Laser-based survey of building objects and buildings
(PhD Thesis;2019:30, Doctoral thesis, 2019)Building information models (BIMs) for facility management is gaining interest. Different technologies for collecting the raw material to extract such model are in rapid development. The most common technologies are based ... -
Machine learning-based perception to identify and localize pickable strawberries for harvester robots
(Phd Thesis;2022:16, Doctoral thesis, 2022)Development of agricultural harvesting robots is one of the solutions to the problems of decreasing labor availability, and improving farm productivity and sustainability. A vision system that can provide reliable detection ... -
Mathematical aspects of localized activity in neural field models
(PhD Thesis;2011:37, Doctoral thesis, 2011)Neural field models assume the form of integral and integro-differential equations, and describe non-linear interactions between neuron populations. Such models reduce the dimensionality and complexity of the microscopic ... -
Methods for estimation of major forest attributes based on remotely sensed data for the support of REDD+ measurement, reporting and verification (MRV)
(PhD Thesis;2021:20, Doctoral thesis, 2021)There is limited information about the status of forest resources in Ethiopia. The available reports based on field sampling are inconsistent and lack precision due to limited sample sizes. Remotely sensed data, which cover ... -
Methods of functional analysis in homogenized neural field theory
(PhD Thesis;2016:66, Doctoral thesis, 2016-11-24)One of the major challenges in neurobiology remains understanding the relationship between complex neural network dynamics underlying spatially structured activity states and the corresponding neural circuitry for which ... -
Microplastics in stormwater runoff : measuring tire wear particles (TWP) concentration in the road environment and effect of treatment systems
(PhD Thesis;2023:16, Doctoral thesis, 2023)Tire wear particles (TWP) are a major source of microplastics that are mainly transported by stormwater from roads to the environment. Their risk has not yet been sufficiently evaluated, mainly because of the lack of ... -
Modeling and analysis of extracellular field potentials in the brain
(PhD Thesis;2010:12, Doctoral thesis, 2010)In order to model processes occuring in the brain it is necessary to have reliable measures of neural activity, with a clear intepretation rooted in the biophysics of the neural tissue. One of the most important probes of ... -
Modelling and control of kinematically complex robotic systems
(PhD Thesis;2015:80, Doctoral thesis, 2018-04-30)This thesis is concerned with modelling and control of kinematically complex robotic systems. The thesis is divided into four main parts. Part I is concerned with a large class of robotic systems, namely vehicle-manipulator ... -
Modelling and optimisation of wastewater coagulation process
(PhD Thesis;2010:05, Doctoral thesis, 2010)The efficiency and economics of chemical coagulation, one of the most robust wastewater treatment processes, is critically dependent on the optimal coagulant dosage which is strongly related to the influent quality. The ... -
Modelling scattering and absorption in the vibrational spectroscopy of cells and tissues
(PhD Thesis;2022:53, Doctoral thesis, 2022)Infrared spectroscopy has in the past decades grown to become one of the most widely used analytical techniques for biochemical characterization of biological materials. Since the technique is non-destructive, it allows ... -
Modular, mobile robots for applications in the agricultural domain
(PhD Thesis;2018:77, Doctoral thesis, 2018)The population of the world is projected to reach almost 10 billion by 2050. To be able to feed everyone, we must increase food production by at least 50%. This must be achieved by a sector already responsible for a quarter ... -
