  1. 1. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

  3. 2. Fault Detection and Diagnosis for Automotive Camera using Unsupervised Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ziyou Li; [2023]
    Keywords : Unsupervised Learning; Autoencoders; Image Clustering; Fault Detection and Diagnosis; Morphological Operations; Hardware-in-Loop; Advanced DriverAssistance System; Oövervakad inlärning; Autoencoders; Bildklustering; Felfindning och Diagnostik; Morfologiska Operationer; Hardware-in-Loop; Avancerade Förarassistanssystem;

    Abstract : This thesis aims to investigate a fault detection and diagnosis system for automotive cameras using unsupervised learning. 1) Can a front-looking wide-angle camera image dataset be created using Hardware-in-Loop (HIL) simulations? 2) Can an Adversarial Autoencoder (AAE) based unsupervised camera fault detection and diagnosis method be crafted for SPA2 Vehicle Control Unit (VCU) using an image dataset created using Hardware-inLoop? 3) Does using AAE surpass the performance of using Variational Autoencoder (VAE) for the unsupervised automotive camera fault diagnosis model? In the field of camera fault studies, automotive cameras stand out for its complex operational context, particularly in Advanced Driver-Assistance Systems (ADAS) applications. READ MORE

  4. 3. “They Told Me The Pills Were Safe” : Understanding the Experience of Iatrogenic Injury from Psychiatric Treatment

    University essay from Uppsala universitet/Sociologiska institutionen

    Author : Amelia Johansson-Everday; [2023]
    Keywords : iatrogenic injury; iatrogenesis; medical harm; medical sociology; critical psychiatry studies;

    Abstract : Iatrogenic injury resulting from psychiatric treatment represents a critical concern within the healthcare system and causes great harm to the afflicted individuals. This study delves into the multifaceted dimensions of iatrogenic harm attributed to psychiatric treatment, with a focus on the interplay between trust, accountability and recognition, and the social and relational experience of receiving treatment that ends up causing harm.

  5. 4. Global Supply Chains at a Crossroads - A multiple case study investigating the process of Volvo Cars’ & H&M Group’s reconfiguration of their global supply chains

    University essay from Göteborgs universitet/Graduate School

    Author : Axel Garå; Jacob Elander; [2022-07-05]
    Keywords : Global Supply Chains; Volvo Cars; H M Group; Risk Management; Reconfiguration; Zone of Balanced Resilience; Capabilities; Global Value Chains; Disruptions; Covid-19; International Business; Resilience;

    Abstract : Globalization and falling barriers to international trade have incentivized firms to relocate activities to foreign markets in pursuit of greater returns. MNCs today often have global supply chains with high degrees of interdependence where a disruption at one end of the supply chain often affects the whole network. READ MORE

  6. 5. Erosionens naturliga skydd : växtens egenskaper och inverkan på yterosionsbildning vid slänter

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Felix Dahlbäck; [2021]
    Keywords : erosion; ; yterosion; slänter; ingenjörsbiologi; water erosion; erosion control; vegetation coverage;

    Abstract : Vårt landskap utsätts hela tiden för förändringar, där både naturliga processer och mänsklig påverkan kan orsaka stora problem. Erosion är en naturlig process men kan påskyndas av människliga aktiviteter, markanvändning och klimatförändringar. READ MORE
