1. 1. Evaluating image analysis techniques for ultrasound optical tomography in breast tissue

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Henrik von Friesendorff; [2023]
   Nyckelord :ultrasound optical tomography; Monte Carlo light simulation; image reconstruction; Technology and Engineering;

   Sammanfattning : Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging. LÄS MER

3. 2. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Jessica McKenna; [2023]
   Nyckelord :Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

   Sammanfattning : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

4. 3. Multiple-Emitter Super-resolution Imaging using the Alternating Descent Conditional Gradient Method

   Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Författare :Dolev Illouz; [2023]
   Nyckelord :super-resolution; alternating descent conditional gradient method; ADCG; multiple-emitter localization; nanoscale imaging; single molecule tracking; Physics and Astronomy;

   Sammanfattning : 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dataset obtained from the 2013 Grand Challenge localization microscopy and a temporally linked dataset obtained from an unpublished set of Optical DNA mapping experiments performed by Jonathan Jeffet at the NanoBioPhotonix Lab at Tel-Aviv University were initially segmented to extract their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.

5. 4. Establishing novel approaches for assessing safety of genome-editing-based therapeutics

   Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Noorul Shaheen Sheikh Farid; [2023]
   Nyckelord :;

   Sammanfattning : Genome editing based medicines are a new therapeutic modality being developed. They show great promise for a spectrum of genetic diseases lacking conventional treatment strategies. A major obstacle that prevents such therapies to reach the clinic is their safety. LÄS MER

7. 5. Volumetric Rendering of the Inner Coma of a Theoretically Modelled Comet for Comet Interceptor Mission

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Amal Vinod; [2023]
   Nyckelord :Volumetric rendering; rendering; Comet; Coma; Dust Coma; Gas Coma; Blender; Comet Interceptor;

   Sammanfattning : The Comet Interceptor is a joint mission by European Space Agency (ESA) and Japan Aerospace Exploration Agency (JAXA) which seeks to perform a flyby over a Long Period Comet using a multi-element spacecraft. The Comet Interceptor comprises three spacecrafts- A, B1 and B2. LÄS MER
