1. 21. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Author : Robert Petersen; [2023]
   Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

   Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

4. 23. Neurotactile Integration

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Kalle Svensson; Julius Cewers; [2023]
   Keywords : Technology and Engineering;

   Abstract : The field of neural representation of sensory integration is an advanced topic with complex processes. The mechanisms of the brain are far from fully understood and are in need of further development to be implemented in clinical usages such as neuroprosthetics. READ MORE

5. 24. Study, Design and Optimization of Micro Coil for NMR Applications

   University essay from Linköpings universitet/Institutionen för systemteknik

   Author : Yuxuan Lu; Xinhang Li; [2023]
   Keywords : NMR;

   Abstract : Nuclear Magnetic Resonance (NMR) has emerged as a powerful tool for the iden-tification and quantification of substances. A critical component within the NMRapparatus is the radio frequency coil, which determines to some extent the sen-sitivity of the NMR device. READ MORE

6. 25. EVOKED PHASE COHERENCE AS A BIOMARKER FOR ADAPTIVE NEUROMODULATION IN RAT MODEL OF PARKINSON'S DISEASE

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Love Zackrisson; [2023]
   Keywords : Adaptive; Closed Loop; Neuromodulation; Parkinson’s Disease; Rat model; 6-OHDA; ITC; Phase Coherence; Bayesian Model; Classifier; Spinal Cord Stimulation; Deep Brain Stimulation.; Adaptiv; Closed Loop; Neuromodulation; Parkinson’s Sjukdom; Råttmodell; 6-OHDA; ITC; Faskoherens; Bayesiansk Modell; Klassificerare; Ryggradsstimulering; Djup Hjärnstimulering.;

   Abstract : Neuromodulation, such as spinal cord stimulation (SCS) and deep brain stimulation (DBS), has been shown to modulate pathophysiological brain activity and provide symptomatic therapy for several neurological disorders, including Parkinson’s Disease. The effectiveness of this therapy could likely be further improved by neuromodulation that is adaptive, delivering stimulation more selectively, by monitoring a biomarker in recorded brain signals, which indicates the presence of a pathological state.
