1. Assessing the Streamline Plausibility Through Convex Optimization for Microstructure Informed Tractography(COMMIT) with Deep Learning
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Tractography is widely used in the brain connectivity study from diffusion magnetic resonance imaging data. However, lack of ground truth and plenty of anatomically implausible streamlines in the tractograms have caused challenges and concerns in the use of tractograms such as brain connectivity study.

2. Extremal Mechanisms for Pointwise Maximal Leakage
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In order to implement privacy preservation for individuals, systems need to utilize privacy mechanisms that privatize sensitive data by randomization. The goal of privacy mechanism design is to find optimal tradeoffs between maximizing the utility of the privatized data while providing a strict sense of privacy defined by a chosen privacy measure.

3. Minimum Cost Distributed Computing using Sparse Matrix Factorization
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : Distributed computing is an approach where computationally heavy problems are broken down into more manageable sub-tasks, which can then be distributed across a number of different computers or servers, allowing for increased efficiency through parallelization. This thesis explores an established distributed computing setting, in which the computationally heavy task involves a number of users requesting a linearly separable function to be computed across several servers.

4. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. LÄS MER
5. Convex Optimization-based Design of a Speed Planner for Autonomous Heavy Duty Vehicles
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : The objective of this master thesis is to design a speed planner for a heavy duty vehicle (HDV) that focuses on achieving a time efficient and comfortable driving, given different constraints such as road geometry, vehicle dynamics, acceleration, deceleration, speed limits etc. through an optimization based approach, namely by formulating it as a convex problem in a receding horizon fashion.
