Evaluation of resolution enhancement in shifted superimposed projection displays: Simulations and experiments
(Doctoral dissertations at the University of South-Eastern Norway;60, Doctoral thesis, 2020)Spatial resolution is one of the key performance parameters of a projected display, and the projector industry continuously aims to increase it. Projector resolution is traditionally based on the resolution of the spatial ... -
Flexible electrochemical sensor platform
(Doctoral dissertations at the University of South-Eastern Norway;54, Doctoral thesis, 2019)Bringing an electroanalytical assay from the laboratory to the level of a commercially or clinically viable product often requires substantial cost, effort and time. While the real value may lie in the assay and sensor ... -
Glucose energy harvester for self-powering of remote distributed bioanalytical microsystems
(Doctoral dissertations at the University of South-Eastern Norway;88, Doctoral thesis, 2021)Implantable medical devices came of age with the artificial pacemaker more than 60 years ago. Their true potential of being located directly where their prosthetic or therapeutic actions are needed will be further enhanced ... -
Heat generation in underwater transducers
