  1. 6. Machine Learning for Sparse Time-Series Classification - An Application in Smart Metering

    Master-uppsats, KTH/Matematisk statistik

    Författare :Carl Ridnert; [2019]
    Nyckelord :;

    Sammanfattning : Smart Meters are measuring devices collecting labeled time series data of utility consumptions from sub-meters and are capable of automatically transmit-ting this between the customer and utility companies together with other companies that offer services such as monitoring of consumption and cleaning of data. The smart meters are in some cases experiencing communication errors. LÄS MER

  3. 7. Feasibility Study of Chemical Energy Storage for an Energy Efficient Commercial Office Space

    Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

    Författare :Kerry-Leigh Maritz; [2019]
    Nyckelord :“Chemical Energy Storage”; “Commercial”; “Energy Storage”; “Load Demand Shift”; “50kW Solar System”;

    Sammanfattning : Shifting the load demand of a commercial office space to utilise off peak tariffs would lead to cost savings as power is cheaper at this time. To achieve this shift, chemical energy storage was considered using Lead Acid batteries, Lithium-ion batteries and Advance Lead Acid batteries. The output of these storage types is electricity.

  4. 8. Energieffektivisering i flerbostadshusområde från 1950-talet : Åtgärder med fokus på minskad energianvändning för uppvärmning av tappvarmvatten

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Maria Nilsson; [2018]
    Nyckelord :Energieffektivisering; flerbostadshus; varmvatten;

    Sammanfattning : The aim of this study was to investigate energy saving measures, primary for reducing the energy use for heating domestic hot water in Gamla Studentstaden, Uppsala. Gamla Studentstaden, a residential area for university students built in the 1950’s, consists of 14 buildings with student dormitories and apartments. LÄS MER

  5. 9. Low Power Wide Area Network (LPWAN) Technologies for Industrial IoT Applications

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nikolaos Tsavalos; Ahmad Abu Hashem; [2018]
    Nyckelord :iot sigfox nb-iot cat-m1 iiot industrial hms coverage capacity latency pycom lund malmo hurva; Technology and Engineering;

    Sammanfattning : Industrial Internet of Things (IIoT) is part of the well-known IoT concept where a large number of devices need to be interconnected in order to collect and exchange data. Companies’ aim is not only to minimize cost during product design, operation and maintenance but also to enable remote monitoring on the efficiency of the devices-assets through the utilization of cloud services.

  7. 10. Non-Invasive Liquid Metering Method Analysis

    Master-uppsats, KTH/Mekatronik

    Författare :Gustav Sten; Thibault Helle; [2018]
    Nyckelord :ultrasonic; liquid; metering; non-invasive; ultraljud; flöde; vätska; icke-invasiv;

    Sammanfattning : The ability to measure flow in pipes often introduces expensive and difficult installations due to existing flow-meters being invasive. To solve this a non-invasive solution has been found by testing and evaluating different mechanical and electrical methods using ultrasonic piezo-crystals and time-of-flight calculations. LÄS MER
