  1. 6. Radio Frequency Energy Harvesting In Embankment Dams

    University essay from Uppsala universitet/Datorteknik

    Author : William Järvström; Axel Lundberg; [2022]
    Keywords : Energy Harvesting; Embankment Dams; Radio Frequency; Wireless Energy Transfer;

    Abstract : Energy harvesting can be used to consume the potential power of the surrounding environment. This harvesting can be done in different ways, some common energy harvesting modalities are vibrations, heat differences, solar power, and RF energy. READ MORE

  3. 7. Energy Usage in Railway Wayside Object Heating : Modeling of melting of Ice, Estimation of heating power requirement in Switch and Renewable energy feasibility for a Railway system

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Sidharth Kapoor; [2022]
    Keywords : Melting of Ice; Numerical modeling; Transient conjugate heat transfer; Transient analysis; CFD; Switch heating; Heat pumps in Railways; Issmältning; Numerisk modellering; Transient värmeöverföring; Transientanalys; CFD; Värmepumpar i järnvägar;

    Abstract : Trafikverket operates about 12000 Switches and crossings (SnCs) of which 6800 are equipped with an electrical heating system of 10−30kW power to keep SnCs functional throughout the winters by keeping them free of Snow/Ice. The energy consumption is approximately 200−130GWh/year costing approximately 10−15 million Euros annually. READ MORE

  4. 8. Damage Criteria for Fibre Optic Cables Exposed to Fire - Using data transfer as functional criterium

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Joakim Åström; Sofia Lindahl; [2021]
    Keywords : Cable; fibre optic cables; data transfer; data loss; functional criterium; damage criteria; bend diameter; temperature; fire conditions; heat flux; cone calorimeter; probabilistic distribution; risk analysis; Technology and Engineering;

    Abstract : The aim of this master thesis was to analyse the possibility to use fibre optic cables for critical safety features in high reliability facilities. In more detail, this report investigates how transferred data in fibre optic cables are affected by fire and if there is any risk that the data becomes corrupted or lost when exposed to fire conditions.

  6. 10. Determination of Mass- and Heat Transfer Coefficients for Computer Modelling of Pharmaceutical Freeze-Drying

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Linnea Gustafsson; [2021]
    Keywords : Freeze-drying; Mass- and Heat Transfer; Pharmaceutical production; Simulation; MATLAB; Pharmaceutical technology; Technology and Engineering;

    Abstract : This thesis work deals with the determination of mass- and heat transfer coefficients for pharmaceutical vial freeze-drying and the one-dimensional steady state computer modelling of primary drying. The overall heat transfer coefficient K_V for the vial/freeze-dryer system was successfully determined using a gravimetric method. READ MORE
