  3. 2. Design Guidelines of A Low Power Communication Protocol for Zero Energy Devices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiayue Zhang; [2023]
    Keywords : Energy efficient communication protocol; sensor data transfer; zero energy devices; battery-less; energy harvesting; Energieffektiv kommunikationsprotokoll; sensordatöverföring; “zero” energienheter; batterifria; energy harvesting;

    Abstract : Lågströmskommunikationsprotokoll såsom 6LoWPAN har använts i stor utsträckning för applikationer som kräver mindre energiförbrukning för trådlös kommunikation på korta avstånd, exempelvis IoT-enheter. Eftersom antalet sådana enheter ökar blir det allt viktigare att överväga ambient energy harvesting som en energikälla för att driva sådana enheter. READ MORE

  4. 3. Evaluating Energy Saving Techniques for Network Requests in Mobile Applications

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Oscar Englöf; [2022]
    Keywords : Energy consumption; Mobile applications; Networking; Battery consumption;

    Abstract : Climate change is one of the most pressing issues today and companies are looking for ways to lower their carbon emissions. Software companies that develop mobile applications have a carbon footprint through several sources. The application uses networking which consumes energy through data transmission across the internet and data centers. READ MORE

  5. 4. Minimizing Transformer No-Load Losses at Hydropower Plants : A Study of Effects from Transformer Switch-Off During Stand-by Operation

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Elin Luedtke; [2021]
    Keywords : step-up transformer; transformer switch-off; stand-by operation; idle operation; transformer winding; inrush current; fatigue stress; fatigue failure; S-N curve; transformer thermal cycling; thermal time constant; saving potential in hydropower; hydropower plant;

    Abstract : Hydropower is the most important power balancing resource in the Swedish electrical power system, regulating the power supply to match the load. Consequently, several hydropower plants have periods of stand-by operation where the power production is absent but where several devices within a plant are still active. READ MORE

  6. 5. Green Access Control System

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Jonas Lundahl; Jos Rosenqvist; [2021]
    Keywords : power consumption; physical access control; embedded systems; Internet of Things; Technology and Engineering;

    Abstract : The number of fixed-installation resource-constrained devices, such as Internet of Things devices, has been growing rapidly in the past years. One challenge of accommodating these large numbers of connected devices is the need to power them all. READ MORE
