Computational Methods for Biomedical Imaging
… We demonstrate the generation of non-diffracting beams using Lee Holography, and argue that the rich depth information made possible by these beams is well-suited for machine learning applications, where 2D images can contain 3D contextual information without the added computational overhead of …

Vibrations of an isolated wind turbine blade using the finite element method
… isolated and twisted wind turbine blade which is rotating in a vertical plane to determine its structural dynamic characteristics. The equations of motion are formulated for a rotating beam with flap and lead-lag degrees of freedom subjected to nonsymmetric bending. Using a variational approach, a …

Effect of Centrifugal Stiffening on the Natural Frequencies of Aircraft Wings During Rapid Roll Maneuvers
… explain the effect of centrifugal stiffening in rotating beams and consequently on the frequencies of the beam. Multiple cases of the rotating beam are explored in this thesis to investigate effects of mass distribution and boundary conditions on the frequencies of centrifugally stiffened beams. …

Generation and application of squeezed light
… phase shift which is induced between a co-rotating and a counter-rotating beam, when the cavity or fiber is in a state of rotation. It is demonstrated that the non-linearity in the fiber medium of a laser gyroscope can be used to produce squeezed light, which leads to a better signal to …

Enhanced Energy Harvesting for Rotating Systems using Stochastic Resonance
Energy harvesting from the rotating system has been an influential topic for researchers over the past several years. Yet, most of these harvesters are linear resonance-based harvesters whose output power drops dramatically under random excitations. This poses a serious problem because a lot of …

Single-Particle Orbit Tracking - Setup, Characterisation and Application
… to do so, special optics which deflect a laser beam and guide it on a circular path were used. Subsequently, this rotating beam is projected by a microscope into the sample with the diffusing particles. Due to the spatially and periodically modulated excitation light, the emission signal of the …
