  1. 1. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Jonathan Envall; [2023]
    Nyckelord :PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Sammanfattning : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  2. 2. Power-sourced charging over PoE to enable high power peaks

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Deshane Devis; Babak Abedpour; [2023]
    Nyckelord :;

    Sammanfattning : In contrast with well-known traditional Closed Circuit Television cam-eras, nowadays most electronic devices including Internet Protocol surveil-lance cameras , Wireless Access Point, Network Routers, Voice over Internet Protocol technologies ,and so forth are all powered throughPower over Ethernet cables. These cables are capable of delivering bothDirect Current power and data simultaneously using a single main cable for the Local area network, this tremendously assisted system integra-tors and network installers to deploy electronic devices in locations that lack electrical circuitry and eventually eliminating the extra expensesof installing additional electrical wiring as well as power supplies.

  3. 3. A Novel Two-Level Inverter Design for Efficient Energy Conversion in a Maglev Train Rail

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Oskar Zetterström; Stefan West Westholm; [2023]
    Nyckelord :IGBT; Inverter; Gate-driver; Prototype; Pulse width modulation; Sine wave; Maglev train; IGBT; Växelriktare; Grinddrivenhet; Prototyp; Pulsbreddsmodulering; Sinusvåg; Maglevtåg;

    Sammanfattning : This report covers the construction of a prototype inverter system designed to power the rail of a maglev train, from component selection through simulations and power demands to mounting and wiring the components into a cabinet. The inverter is made with insulated gate bipolar transistors controlled with pulse-width modulated signals provided by a custom microcontroller. LÄS MER

    Sammanfattning : This project has been carried out at the Electronic Embedded Systems Architecture Department at Volvo Construction Equipment (VCE), Eskilstuna, Sweden. It forms the baseline for a stepwise systematic research initiative to convert wired technologies used for certain in-vehicle control and communication components to wireless technologies. LÄS MER

  5. 5. Quantification of emissions in the ICT sector – a comparative analysis of the Product Life Cycle Assessment and Spend-based methods. : Optimal value chain accounting (Scope 3, category 1)

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Abhishek kumar Rajesh Jha; [2022]
    Nyckelord :ICT sector; Scope 3 category 1 emissions or Optimal value chain emissions; CO2e emissions; GHG protocol; PLCA; Spend-based; Smartphones; Laptops; Display; Printed Wiring Board; Integrated Circuit; Solid State Drive; EMLCA; Sensitivity analysis Uncertainty analysis.;

    Sammanfattning : Considering the rapid increase in the ICT (Information & Communication Technology) products in use, there is a risk of an increase in GHG emissions and electronic waste accumulation in the ICT sector. Therefore, it becomes important to account for the emissions in the ICT sector in order to take steps to mitigate them. LÄS MER
