1. Domain Knowledge and Representation Learning for Centroid Initialization in Text Clustering with k-Means : An exploratory study
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Text clustering is a problem where texts are partitioned into homogeneous clusters, such as partitioning them based on their sentiment value. Two techniques to address the problem are representation learning, in particular language representation models, and clustering algorithms. LÄS MER
2. Identifiering av felplacerade komponenter på ett kretskort med bildbehandling
Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Avdelningen för datavetenskap och samhällsbyggnadSammanfattning : Teknologiska framsteg påverkar tillverkningsindustrin genom att integrera tester för kretskortens status, lödning och elektriska egenskaper. En pick-and-place-maskin används för att verifiera komponentpositioner på kretskortet, men underhåll och re-paration av dessa maskiner medför stora kostnader. Industry 4. LÄS MER
3. Distance-Based Formation Control, Maneuvering and Flip Ambiguity Avoidance in Multi-Agent Systems
Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Formation control is a fundamental concept in the field of robotics, where a group ofagents is directed to achieve a specific formation or pattern. This report investigates decentralizeddistance-based formation control strategies for multiagent formation control, with a focus on controllaw design dealing with flip ambiguity issues, and centroid maneuvering.

4. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches
Master-uppsats, KTH/FysikSammanfattning : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. LÄS MER
5. Determination of Proton Beam Waist Positions Using Beam Position Monitors
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/SynkrotronljusfysikSammanfattning : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.
