Tool Coating is a method for enhancing cutting efficiency and extending tool life, essential for machining hard materials. While Polycrystalline Cubic Boron Nitride (PcBN) tools are already well-suited for harsh machining conditions, their durability can be further improved with coatings. However, as the machining operation continues, tool coating loss occurs, reducing the durability of the tool a
Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth. Several members of Odonata are known to migrate long distances and have conside
0D Sb3+-based organic-inorganic hybrid metal halide (OIMH) scintillators have gained significant attention due to their efficient self-trapped exciton (STE) emission. However, the interplay between local structural distortion, defect-states, and STE emission remains insufficiently understood. Herein, two structurally distinct 0D Sb3+-based OIMHs, [HP(o-tol)3]2SbBr5 and [HP(m-tol)3]4SbBr7, are inve
The RELOC-AGE program addresses knowledge gaps on associations between housing, relocation, and active and healthy aging. The aim of this study was to investigate preferred housing attributes, and whether such attributes differed depending on desired type of dwelling or individual characteristics, among adults in Sweden aged 55 years and older with an expressed interest in relocation. From the Pro
The present nationwide population-based study compared minimally invasive surgery (MIS) with open surgery (OPEN) for colorectal cancer during a period when MIS was introduced in Sweden. The primary analyses demonstrated that MIS was not inferior compared with OPEN regarding short-term outcome for patients operated 2012-2018, nor for long-term outcome assessed as overall survival with surgery perfo
Magnetic fields are a key factor in the evolution of planets and their atmospheres, but they are still poorly constrained for exoplanets owing to limited direct observations. Ultra-hot Jupiters provide a new avenue to probe magnetic effects, as the circulation of their highly ionized atmospheres could be directly sensitive to the atmospheric magnetic field. However, it remains unclear whether the
Symptomatic knee osteoarthritis at an early structural stage could provide a window of opportunity for intervention. Symptomatic knees without definite radiographic osteoarthritis can already show structural joint changes detectable on MRI; however, the greater sensitivity of MRI must be balanced against the risks of overdiagnosis and overtreatment.
Thyroid function has been suggested to be associated with breast cancer risk, but not much is known about thyroid hormones as a potential prognostic factor for breast cancer. This study investigated the relation between thyroid hormones in breast cancer patients and mortality. A total of 2000 breast cancer patients from the Swedish SCAN-B cohort were followed for 9 years. Blood samples were collec
There is currently widespread concern that rapid technological change will funda-mentally change the nature of work. In this paper we show that, despite 140 years oftechnological change, more than 70 percent of employment today is located in occu-pations whose core economic functions already existed in the late nineteenth century.Full-count Swedish census and administrative data from 1880 to 2019,
Industrial robotic manipulators are widely used in manufacturing for high-speed pick-and-place operations. Therefore, there is value in optimizing the trajectory execution speed and positional accuracy to reduce cycle times. However, pushing these acceleration limits often induces structural residual vibrations at the end-effector, which degrade process quality and necessitate long settling times.
At the European Spallation Source (ESS), the Beamline for European materials Engineering Research (BEER) instrument aims to position samples within the neutron beam using a robotic arm system, given the high flexibility and large end-effector workspace provided by robotic arms. However, precise and accurate sample positioning is limited by the pose accuracy capabilities of industrial robotic arms,
Single-cell RNA sequencing (scRNA-seq) has opened new possibilities for studying the dynamic interplay between circadian rhythms and cell cycle progression at the level of individual cells. This thesis explores circadian-related transcriptional signals and their possible relationship with cell cycle activity in human bone marrow cells using publicly available scRNA-seq data from healthy donors. Si
Recent advancements in GPU-accelerated simulation have made it possible to train reinforcement learning policies for robotic control using large-scale parallel data collection. This thesis explores the pipeline from task description to deployment of control policies on the robot platform Spot. The focus is on two important skills needed for future loco-manipulation tasks: robust standing and comma
The purpose of a calorimeter thermostat is to keep a stable internal temperature for a sample of some chemical compound, so that the heat production rate of chemical processes in the sample can be measured without disturbances. However, there may be external disturbances to the calorimetric process, for instance changes in ambient temperature in the room where the calorimetric instrument is locate
Fungal pathogens in soil threaten global food security. Recent developments in microfluidics and image analysis provide novel ways to image and identify fungal pathogens, but these require high-resolution images taken by research-level microscopes. Affordable tools for in-situ soil microorganism imaging therefore remain unavailable. Fourier Ptychographic Microscopy (FPM) offers a route towards suc
Demands for accurate industrial robots has driven an increasing need for accessible and reliable calibration methods. Robot manipulators operating in environments where large external forces are present, or carrying heavy tools, suffer from inaccuracies caused by joint elasticities, both from external loads and from gravity acting on the robot links themselves and on the payload. Calibration metho
Pellet–Cladding Interaction (PCI) remains one of the most important fuel reliability concerns in boiling water reactors (BWRs), particularly for fuel rods located in close proximity to control rods. PCI-related fuel failures can result in unplanned reactor shutdowns, costly maintenance activities, and reduced operational flexibility. This thesis investigates different operational strategies aimed
Performance control in servers is important for maintaining responsiveness and efficient resource usage, particularly in smaller computing environments where resource bottlenecks are more noticeable. This creates a need for mechanisms to measure and control the performance of common bottlenecks such as disk I/O and networking. This thesis investigated and compared two different methods for control
This thesis presents the development and evaluation of an embedded hardware and software platform for future Hardware-in-the-Loop (HIL) based motor testing at ASSA ABLOY Entrance Systems. The motivation for the work is to reduce the number of physical door setups required for motor testing by complementing them with a configurable HIL rig capable of simulating different door types and configuratio
This thesis investigated how machine learning-based anomaly detection can be applied to support predictive maintenance for a radar system using available monitoring data. An LSTM autoencoder was trained on selected healthy running operation and used to detect deviations in multivariate sensor windows based on reconstruction error. The anomaly score was combined with report information and a rule-b
