  1. 11. Estimating Risks of Pharmaceutical NSAID Mixtures in Surface Waters through Risk Cups : – Implications for Sustainability

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Per Mandahl; [2020]
    Nyckelord :Sustainable Development; Ecotoxicology; Risk Cup; Pharmaceuticals; Surface Water; MEC PNEC;

    Sammanfattning : Background: Use of pharmaceuticals can lead to unchanged or metabolite residues in surface water that may result in negative environmental effects. Sweden has adopted the Generational goal defining direction and changes needed to become a sustainable nation, these align with the UN Sustainable Development Goals (SDGs). LÄS MER

  3. 12. Evaluation of Homogeneity in Drug Seizures Using Near-Infrared (NIR) Hyperspectral Imaging and Principal Component Analysis (PCA)

    Kandidat-uppsats, Linköpings universitet/Kemi

    Författare :Olle Strindlund; [2020]
    Nyckelord :Homogeneity; drug seizures; pharmaceuticals; NIR hyperspectral imaging; chemometrics; PCA;

    Sammanfattning : The selection of a representative sample is a delicate problem when drug seizures comprised of large number of units arrive at the Swedish National Forensic Centre (NFC). If deviating objects in the selected sample size are found, additional analyzes are required to investigate how representative the results are for the entire population. LÄS MER

  4. 13. Experiments on optimal maintenance operations with emphasis on end-of-contract constraints

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Sebastian Ahlman; Philip Nilsson; Tanha Kamran; [2019-06-18]
    Nyckelord :;

    Sammanfattning : To minimize the unnecessary costs that arise when machines or other objects fail, perhaps needing to be replaced during less than ideal occasions through what is known as reactive maintenance, a more active maintenance policy through which objects are continuously maintained in a preventative manner based on life expectancy or from a cost-perspective, is preferred. Mathematical models can be advantageous to utilize when scheduling these maintenance occasion. LÄS MER

  5. 14. ROI Calculation on Online Controlled Experiment

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Richard Wang; [2019]
    Nyckelord :A B testing; Online Controlled Experiments; Return on Investment; ROI; Mathematics and Statistics;

    Sammanfattning : As online services such as e-commerce and mobile applications keeps growing, the need of optimizing the user experience does as well. By conducting Online Controlled Experiments, companies can get an insight to which features, design choices and implementations that users enjoy the most. LÄS MER

  7. 15. Capability Perception of an Electric Utilityduring Sectoral Change towards Sustainability

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Christopher Politano; [2018]
    Nyckelord :;

    Sammanfattning : This thesis examines the antecedents of employees’ capability cognition within a medium-sized electricity utility (Ntot 􀵎 1200) in German-speaking Switzerland. The firm implemented a new strategy in 2015 with the aim to shift its core capabilities towards sustainability. LÄS MER
