1. 1. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia

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

   Author : Calum Kvernes Macpherson; [2023]
   Keywords : Bulge; Milky Way; Kinematics; Galpy; Dwarf Stars; Physics and Astronomy;

   Abstract : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

3. 2. Pen-rotation scheme for growing pigs : effects on pig aggression and social affiliation

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Moses Agbenyegah Gadri; [2023]
   Keywords : aggressive; affiliative; fighting; littermates; behaviours; reuniting;

   Abstract : This master project aimed to assess if a pen-rotation scheme mitigated the effects of reuniting pigs after temporal separation. Six groups of crossbred (Yorkshire and Hampshire) growing pigs, (8 - 10 littermates per group) aged between 12 – 13 weeks, were video recorded separately in their original home pens for 2 h before a temporal separation to undergo the pen rotation scheme in pairs for 3 days.

4. 3. An Introduction to p-adic Analytic Groups

   University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Author : Frieder Selisko; [2023]
   Keywords : Mathematics and Statistics;

   Abstract : In this thesis we introduce the concept of a p-adic analytic pro-p group. To do so we discuss important theorems and concepts connected to more general types of groups, these include profinite groups, pro-p groups, powerful p-groups, powerful pro-p groups and uniform groups...

5. 4. Collision Avoidance for Complex and Dynamic Obstacles : A study for warehouse safety

   University essay from Linköpings universitet/Reglerteknik

   Author : Sandra Ljungberg; Ester Brandås; [2022]
   Keywords : Object Detection; Object Tracking; Obstacle Avoidance; Collision Avoidance; Automated Guided Vehicle;

   Abstract : Today a group of automated guided vehicles at Toyota Material Handling Manufacturing Sweden detect and avoid objects primarily by using 2D-LiDAR, with shortcomings being the limitation of only scanning the area in a 2D plane and missing objects close to the ground. Several dynamic obstacles exist in the environment of the vehicles. READ MORE

6. 5. Identification of Potential Sources of Measurement Errors in an Isokinetic Dynamometer : Reliability Analysis of Shoulder Abduction and Flexion Data

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Malena Grannerud; [2022]
   Keywords : Isokinetic dynamometer; shoulder abduction; shoulder flexion; rotator cuff; torque; load; force; repeatability; reproducibility; reliability; agreement; ICC; intraclass correlation coefficient; Bland Altman; Isokinetisk dynamometer; axelabduktion; axelflexion; rotatorcuff; vridmoment; last; kraft; repeterbarhet; reproducerbarhet; tillförlitlighet; överensstämmelse; ICC; intraklass korrelationskoefficient; Bland Altman;

   Abstract : The evaluation of shoulder abduction and flexion strength is important in the rehabilitation after rotator cuff tear. The purpose of this work is to assess the intra and inter-rater reliability of measurement data from an isokinetic dynamometer used to evaluate shoulder abduction and flexion strength, with the aim to identify sources of measurement errors and suggest improvements.
