1. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method
University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisationAbstract : This thesis examines the state-of-the-art 2D super-resolution technique alternating descent conditional gradient (ADCG) method's ability to accurately localize fluorophores in diffraction-limited single molecule images (SMI) and analyze the impact of pre-processing and post-processing modules on ADCG's fluorophore localization. A synthetic dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their noise parameters.

2. Leveraging Posits for the Conjugate Gradient Linear Solver on an Application-Level RISC-V Core
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Emerging floating-point arithmetics provide a way to optimize the execution of computationally-intensive algorithms. This is the case with scientific computational kernels such as the Conjugate Gradient (CG) linear solver. Exploring new arithmetics is of paramount importance to maximize the accuracy and timing performance of these algorithms. READ MORE

3. A Comparison of Selected Optimization Methods for Neural Networks
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : Which numerical methods are ideal for training a neural network? In this report four different optimization methods are analysed and compared to each other. First, the most basic method Stochastic Gradient Descent that steps in the negative gradients direction.

4. Computation of Stationary States for Rotating Bose-Einstein Condensates using Spectral Methods
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : The Bose-Einstein condensate is a phase of matter that arises when cooling gases of bosons to extremely low temperatures. When studying these condensates one may use the Gross-Pitaevskii equation, which is a non-linear variant of the Schrödinger equation. READ MORE

5. Real-time imaging of cerebrospinal fluid flow physiology at 7T
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Background The cerebrospinal fluid (CSF) is involved in several diseases and patho- physiological states, such as Alzheimer’s disease and hydrocephalus. Previous studies CSF dynamics in the brain show that the flow of the CSF depends on cardiac pulsation, time of day and respiration. READ MORE
