  1. 1. MOSIPPA (Pulsatilla vernalis) Att föröka en hotad art ex-situ

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Malin Norrman; [2020-09-16]
    Nyckelord :Pulsatilla vernalis; Ex situ; In situ; Propagation; Horticulture; Nature Conservation; Garden Conservation; Biodiversity; Threatened species;

    Sammanfattning : The purpose of my research has been to collect and report the propagation method around the threatened species Spring pasque flower (Pulsatilla vernalis), and to form a template for what a propagation manual could look like. The material was collected at the Gothenburg Botanical Garden and at Remmene shooting range in Vårgårda. LÄS MER

  2. 2. Sensors for intelligent and reliable components

    Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pontus Lundman; [2020]
    Nyckelord :Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

    Sammanfattning : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.

  3. 3. Multi-Constrained Network Occupancy Optimization

    Magister-uppsats, Mälardalens högskola/Inbyggda system; Mälardalens högskola/Inbyggda system

    Författare :Amar Halilovic; Nedim Zaimovic; [2020]
    Nyckelord :;

    Sammanfattning : Increasingly different types of information are required in systems, resulting in the diverse and widespread use of networks. The increase in the number of devices on networks significantly increases network traffic and network load, limiting network propagation speed, and increasing the possibility of collisions and lost information.

  4. 4. Monitoring and Modelling of the Abiskojåkka Bridge

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Furenstam; [2020]
    Nyckelord :Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

    Sammanfattning : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. LÄS MER

  5. 5. Fretting fatigue life analysis for a gas turbine compressor blade-disk material combination

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Elham Khoramzad; [2020]
    Nyckelord :;

    Sammanfattning : In order to analyse fretting fatigue life of dove-tail joints used in the compressor stage of a gas turbine, experimental study of different material combinations was conducted using rectangular fatigue specimen and bridge type pads. Specimen and pad interaction was simulated numerically and obtained results was used as input for 2 different crack propagation life prediction methods. LÄS MER
