  1. 1. Wireless Sensor Network for Controlling the Varroasis Spread within Bee colonies across a Geographical Region

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Venkat Sai Akhil Dasyam; Saketh Pokuri; [2024]
    Nyckelord :Wireless Sensor Networks; Monitoring and Control; Precision Beekeeping; Disease spread; Internet of Things.;

    Sammanfattning : Background: With the global decline of honey bee populations, safeguarding these vital pollinators has become crucial. Varroa destructor mites are a primary threat, weakening bees and facilitating the spread of diseases, which can decimate colonies and disrupt ecosystems. LÄS MER

  3. 2. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jean-Pierre Hamzo; [2023]
    Nyckelord :CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Sammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER

  4. 3. Thermal Imaging-Based Instance Segmentation for Automated Health Monitoring of Steel Ladle Refractory Lining

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Emil Bråkenhielm; Kastrati Drinas; [2022]
    Nyckelord :Computer Vision; Deep Learning; Thermal Imaging; Instance Segmentation; Mask R-CNN; Steel Ladle Breakout Prevention;

    Sammanfattning : Equipment and machines can be exposed to very high temperatures in the steel mill industry. One particularly critical part is the ladles used to hold and pour molten iron into mouldings. A refractory lining is used as an insulation layer between the outer steel shell and the molten iron to protect the ladle from the hot iron. LÄS MER

  5. 4. Field Oriented Current Control with Harmonic Injection in a Six-Phase Induction Machine

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xinyue Shan; [2021]
    Nyckelord :Multi-phase machine; asymmetrical six-phase induction machine; harmonic plane decomposition; indirect rotor field oriented control; parameter estimation; Flerfasmaskin; asymmetrisk sexfasinduktionsmaskin; harmonisk plan sönderdelning; indirekt rotorfältorienterad styrning; parameteruppskattning;

    Sammanfattning : As a new type of machine, the multi-phase machine has the advantages ofhigher power rating, higher fault tolerance capability and more degrees offreedom to control compared with the traditional machine. Aiming at runninga multi-phase machine with different phase-pole configurations smoothly,a new method called harmonic plane decomposition is presented. LÄS MER

  7. 5. Mathematical modelling of Degussa Furnace

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Rans Faraydoun Muhammed; [2021]
    Nyckelord :Furnace; CFD; ANSYS; Thermodynamic model; Exchange time; Ugn; CFD; ANSYS; Termodynamisk model; Utbytestid;

    Sammanfattning : The energy demands in the world is rapidly increasing and with this,  a supply nuclear  power  is  of  much  interest.    Nuclear  fuel  is  relatively  efficient  when comparing to power sources like wind­ and hydropower plants. LÄS MER
