  1. 1. Analysis of an Ill-posed Problem of Estimating the Trend Derivative Using Maximum Likelihood Estimation and the Cramér-Rao Lower Bound

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Muhammad Farhan Naeem; [2020]
    Nyckelord :carbon dioxide levels; Keeling Curve; Taylor and Fourier series; Maximum Likelihood Estimation; MLE; Cramér-Rao Lower Bound; CRLB;

    Sammanfattning : The amount of carbon dioxide in the Earth’s atmosphere has significantly increased in the last few decades as compared to the last 80,000 years approximately. The increase in carbon dioxide levels are affecting the temperature and therefore need to be understood better. LÄS MER

  2. 2. Transient Stress and Strain Assessment of Marine Boiler : Fully Rigid Body Dynamics Coupled Finite Element Analyses

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Sohail Anwar; [2020]
    Nyckelord :Seakeeping; FEA; Strain; Stress; RAO; Rigid; Body; Dynamics; Finite; Element;

    Sammanfattning : Operationally, marine components and structures such as boiler in a Ship, are exposed to varying mechanically and thermally induced forces. High-frequency mechanical loading arises from the cyclic pressure, temperature transients, and six directional Rapid Amplitude Operator (RAOs). LÄS MER

  3. 3. Thermo-Mechanical Fatigue Assessment of Marine Boiler : Using linear Finite Element Analyses

    Magister-uppsats, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Adefemi Samuel Alagbada; [2020]
    Nyckelord :Marine Boiler; FEA; Thermo-mechanical Loading; LEFM; Paris law; Flaws; RAO.;

    Sammanfattning : This thesis is on fatigue crack growth assessments of a thermomechanical loaded Marine Boiler- Sunrod CPDB12. The installation position of the marine boiler in the ship in relation to its fatigue life under mode 1 loading is investigated. LÄS MER

  4. 4. Deployment Strategies for High Accuracy and Availability Indoor Positioning with 5G

    Master-uppsats, Linköpings universitet/Reglerteknik; Linköpings universitet/Reglerteknik

    Författare :Jesper Ahlander; Maria Posluk; [2020]
    Nyckelord :Indoor positioning; 5G; Cramér-Rao Lower Bound; Time Difference Of Arrival; Round Trip Time; Geometric Dilution Of Precision; Availability; Accuracy; Deployment strategies; Line-Of-Sight; Interference;

    Sammanfattning : Indoor positioning is desired in many areas for various reasons, such as positioning products in industrial environments, hospital equipment or firefighters inside a building on fire. One even tougher situation where indoor positioning can be useful is locating a specific object on a shelf in a commercial setting. LÄS MER

  5. 5. A Comparative Analysis of Argumentation Languages in the Context of Safety Case Development

    Magister-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Sirisha Bai Govardhan Rao; [2019]
    Nyckelord :safety case argumentation languages; safety case argumentation notations; documentation of safety cases;

    Sammanfattning : The safety case creation has become an explicit requirement in most of the safety-critical domains to ensure the safety of a system or an application. In the process of developing a safety case, the foremost requirement is choosing an efficient argumentation language which fulfills all the functionalities needed to develop a safety case. LÄS MER
