  1. 6. A study of productivity measurement and modeling of inhaler production at AstraZeneca

    University essay from Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Author : Vilma Björk Öhhrfelt; Ebba Österman; [2023]
    Keywords : Produktivitet; produktivitetsmått; produktionsplanering; diskret händelsestyrd simulering; kapacitetsförändringar; produktionslogistik; Industriell ekonomi; Industriell ekonomi;

    Abstract : Production planning and evaluation can be performed using various tools. This study encompasses two main topics: productivity measurement and production simulation. The study was conducted at AstraZeneca, a pharmaceutical company, where their production of inhalers was examined. READ MORE

  3. 7. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

    University essay from Linköpings universitet/Avdelningen för medicinsk teknik

    Author : Kristos Qiqi; [2023]
    Keywords : brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

    Abstract : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. READ MORE

  4. 8. Off-State Stress Effects in AlGaN/GaN HEMTs : Investigation of high-voltage off-state stress impact on performance of and its retention in hybrid-drain ohmic gate AlGaN/GaN HEMTs

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

    Author : Ivan Krsic; [2023]
    Keywords : HEMT; GaN; off-state stress; memory effects; drain leakage current; dynamic RDSon; threshold voltage instabilities; charge redistribution; HEMT; GaN; stress i avslaget tillstånd; minneseffekter; läckströmmen; dynamisk RDSon; instabiliteten hos styrets tröskelspänning; omfördelningen av laddningar;

    Abstract : High electron mobility transistors (HEMTs) realized using AlxGa1-xN/GaN are relatively new technology which is prominent for high-speed and high-power applications. Some of the main problems with this technology were identified as dynamic RDSon, current collapse and threshold voltage instabilities due to the off-state stress. READ MORE

  5. 9. A Borel-Cantelli lemma for non-stationary dynamical systems

    University essay from Lunds universitet/Matematik LTH

    Author : Teodor Åberg; [2023]
    Keywords : Borel-Cantelli lemmas; Dynamical systems; Mathematics and Statistics;

    Abstract : In this thesis we present a Borel–Cantelli lemma for dynamical systems such that the dynamics driving the system varies with time. These results are largely based on a decomposition of transfer operators produced by Rychlik. Some limitations on the structure of sequences that is necessary for the results is given some discussion. READ MORE

  6. 10. Cloning and expressing the genes encoding Glycerol dehydratase (GDHt) and 1,3-Propanediol dehydrogenase (1,3-PDDH) in E. coli

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Eleni Pechlivani; [2023]
    Keywords : 1; 3-Propanediol; Glycerol dehydratase; 3-Propanediol dehydrogenase; Glycerol dehydratase reactivase; E. coli; Protein expression; Biotechnology; Technology and Engineering;

    Abstract : The biodiesel sector has witnessed tremendous growth in recent years, leading to a significant increase in glycerol production as a by-product. Addressing the challenge of glycerol valorization is crucial for the sustainability of the biodiesel industry. READ MORE
