1. Fabry-Pérot based refractometry : development of a transportable refractometer for assessment of gas pressure
Abstract : A unified description of physical phenomena through measurement science is one of the foundational pillars in a global society. The International System of Units (SI) is the most widely used system of units and since its redefinition in 2019, all units encompassed by it are based on fundamental physical constants. READ MORE

3. Middle Ear Pressure; A New Method for Continuous Direct Measurements
Abstract : Disturbances in the pressure homeostasis of the middle ear (ME) system cause a pressure gradient across the tympanic membrane lessen the effectiveness of sound transmission and may be associated to development of chronic ME disease. An equipment for continuous direct pressure measurements was developed and was found to be accurate, base-line stabile and portable. READ MORE

4. Fluid Dynamics of Fluidized Bed Reactors: Experiments and Simulations with System Interactions
Abstract : This thesis is a study of the interaction between the fluidized-bed dynamics and the pressure and flow pulsations from the air-supply system. The interaction has been identified as a key process to understand in order to correctly formulate inlet boundary conditions in numerical modelling of fluidized beds, operated under industrial conditions.
