Data-Driven Adaptive Control of Unmanned Surface Vehicles Using Learning-Based Model Predictive Control

In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. The objectives were to assess the resulting controller’s path-following ability

Evidence of Unrecognized Indoor Exposure to Toxic Chlorophenols and Odorous Chloroanisoles in Denmark, Finland, and Norway

Production and use of chlorophenols (CPs) are being phased out around the globe, but with considerable lag in some highly populated countries. The process could be incentivized by leading countries sharing their experiences on problems that occurred, including the built environment. We previously reported that Swedish industry and authorities promoted CPs, including pentachlorophenol (PCP), as wooProduction and use of chlorophenols (CPs) are being phased out around the globe, but with considerable lag in some highlypopulated countries.

Evaluate Transformer model and Self-Attention mechanism in the Yangtze River basin runoff prediction

Study region: In the Yangtze River basin of China. Study focus: We applied a recently popular deep learning (DL) algorithm, Transformer (TSF), and two commonly used DL methods, Long-Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU), to evaluate the performance of TSF in predicting runoff in the Yangtze River basin. We also add the main structure of TSF, Self-Attention (SA), to the LSTM and G

The Complex Exhumation History of Jezero Crater Floor Unit and Its Implication for Mars Sample Return

During the first year of NASA's Mars 2020 mission, Perseverance rover has investigated the dark crater floor unit of Jezero crater and four samples of this unit have been collected. The focus of this paper is to assess the potential of these samples to calibrate the crater-based Martian chronology. We first review the previous estimation of crater-based model age of this unit. Then, we investigate

CW-laser radar for combustion diagnostics

A CW-laser radar system developed for combustion diagnostics is described. It is based on triangulation to attain range information. Some initial results from measurements in sooting flames are shown and some future perspectives are discussed.

The transformation of rainfall into runoff is one of the most important processes in hydrology. In the past few decades, a wide variety of automated or computer-based approaches have been applied to model this process. However, many such approaches have an important limitation in that they treat the rainfall-runoff process as a realization of only a few parameters of linear relationships rather th

Strain-specific metabarcoding reveals rapid evolution of copper tolerance in populations of the coastal diatom Skeletonema marinoi

Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw

Coronary microvascular dysfunction in Takotsubo syndrome and associations with left ventricular function

Aims: Coronary microvascular dysfunction (CMD) has been proposed as an important pathophysiological mechanism in Takotsubo syndrome (TTS). Our aims were (i) to evaluate and compare levels of CMD in patients with TTS and patients with ischaemia and no obstructive coronary arteries (INOCA) and (ii) to investigate associations between CMD and clinical parameters, left ventricular function, and corona

Radix Polygalae Extract Attenuates PTSD-like Symptoms in a Mouse Model of Single Prolonged Stress and Conditioned Fear Possibly by Reversing BAG1

Radix Polygalae (RP) has been used to relieve psychological stress in traditional oriental medicine. Recently, cell protective, antiamnestic and antidepressant-like effects were disclosed but the possible application of RP to post-traumatic stress disorder, in which exaggerated fear memory persists, has not yet been explored. For this purpose, the effects of RP on fear behavior was examined in a m

Creativity seems to be a concept exclusively for spiritual and eccentric people. Musicality ismostly associated with the idea of talent given from birth. However, these concepts areinevitable for the professional musician. The main objective of this thesis is to answer what iscreativity and musicality for a musician. This thesis concerns a clarification of these conceptsand tries to mold them into

Fagott och ergonomi. Att spela fagott utan skador.

Under mina år som fagottist så har jag de senaste fyra fem åren brottats med smärtor i framför allt min vänstra arm och axel. Skadorna uppstod av dålig hållning och spändhet som i sin tur ledde till överbelastning utav muskler. Vad finns det för metoder för att få bukt på smärtproblematik för mig som fagottist? Det här är den beskrivande delen av mitt examensarbete som handlar om hur jag under minDuring my years as a bassoonist, I have for the past four five years been afflicted with pain, especially in my left arm and shoulder. The injuries were caused by poor posture and muscular tension, which led to muscular overload. What are the methods for getting rid of pain problems for me as a bassoonist? This Bachelor thesis deals with how I have worked with ergonomic methods to reduce pain in m

Regenerating Land, Regenerating Self: Towards a Care-full Regeneration Cycle of Inner-Outer Transformation

The world needs rapid transformation if we are to shift towards more just and regenerative socio-ecological futures. In merging scholarly fields of transformation studies, regeneration and ethics of care this thesis explores the connection between inner-outer regeneration through the in-depth study of a transformative caring process. With a focus on lived experience and affects, this study conduct

Factors affecting performance of fetal blood T2 measurements for noninvasive estimation of oxygen saturation

PurposeTo ultimately make accurate and precise fetal noninvasive oxygen saturation (sO2) measurements by T2-prepared bSSFP more widely available by systematically assessing error sources in order to potentially reduce perinatal mortality in cardiovascular malformations and fetal growth restriction.MethodsT2-prepared bSSFP data were acquired in phantoms; in flowing blood in adults in the superior s

What Is Infrastructural Meaning-Making and Why Do We Need It?

Social media, search engines, and recommendation systems provide a constant stream of data that shapes our knowledge, beliefs and decisions. We are constantly presented with content from a variety of sources, often without context. This content gets amalgamated into new constellations in the feeds, lists and streams we encounter (and sometime curate) on our devices. With the rise of consumer-facin

Combination of 1D laterally constrained inversion and 2D smooth inversion of resistivity data with a priori data from boreholes

Resistivity imaging in combination with borehole information is a powerful tool for site investigation. We show that the combination of 1D laterally constrained inversion (1D-LCI) with the use of a priori information from borehole data and 2D smooth inversion adds significant value to the interpretation of continuous vertical electrical sounding (CVES) data. The 1D-LCI offers an analysis of the re

"Som mamma betalar påverkar det mina kläder" : En uppsats om svenska ungdomars identitetsbildning genom mode och hur de påverkas i relation till sina kläder

This paper takes a closer look at a Swedish group of teenagers' usage of fashion in their identity development in an effort to contribute to the understanding of fashion usage in youth culture. By involving them in discussions and interviews, and basing it in theory this paper comes to a somewhat understanding in how phenomena such as religion, gender identity, and celebrity influence the way

Safeguarding Food Industry : Understanding Cyberthreats and Ensuring Cybersecurity

The food industry stands as one of the most vital manufacturing sectors globally, with an ever-increasing reliance on digitalization and technology-driven processes. However, this advancement comes with an inherent risk of cyberattacks, encompassing data breaches and system disruptions, which can severely impact production and disrupt the entire food supply chain. Consequently, such cyberthreats c
