  3. 22. Investigating the Relation Between Microcredit and Female Entrepreneurship in Lao PDR

    Magister-uppsats, Linköpings universitet/Nationalekonomi

    Författare :Klara Granath; Karin Kling; [2018]
    Nyckelord :Microcredit; Microlending; Microfinance; Female Entrepreneurship; Women’s Entrepreneurship; Lao People s Democratic Republic; Interest Rate; Grace Period; Loan Size; Networking; Motivation; Gender Division of Labor; Sexual Division of Labor; Business Training;

    Sammanfattning : Even though the idea of microcredit is to stimulate entrepreneurial activities in developing countries, there is an ongoing debate whether this is achieved. Many argue that only providing credit is not enough and see a need for additional components in promoting entrepreneurial activities for the stimulation of economic growth. LÄS MER

  4. 23. Bio-inspired approach for improving performance of information routing in Vehicular Ad Hoc Networks

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :DAN NGUYEN; KARL HANSEN; [2018]
    Nyckelord :;

    Sammanfattning : As a key technology for Intelligent Transportation Systems (ITS), vehicle-2-vehicle (V2V) communication enables the interconnection of vehicles to limit emissions, decrease congestion, increase traffic safety and much more. Vehicular Ad-hoc Networks (VANETs), a subset of Mobile Ad-hoc Networks (MANETs) is a peerto-peer network among vehicles that is utilized to route information through different forwarding algorithms.

    Nyckelord :LPWAN; IoT; LoRa; SigFox; NB-IoT; Internet of Things; LPWAN; IoT; LoRa; SigFox; NB-IoT; sakernas internet;

    Sammanfattning : Low Power Wide Area Networks (LPWAN) are able to combine long range communication with a low energy consumption sacrificing performance in terms of bit rate and message frequency. This thesis presents a general evaluation of the LPWAN characteristics and a description of the LPWAN protocols LoRaWAN, SigFox and NB-IoT. LÄS MER

  7. 25. Feasibility Study of Indoor Positioning in a Hospital Environment Using Smartphone Sensors

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Joakim Skytte; [2017]
    Nyckelord : Indoor positioning ; smartphone; IMU; Wi-Fi; Dead Reckoning ; Inomhuspositionering; tröghetsnavigering; wifi;

    Sammanfattning : This thesis is a feasibility study of contemporary indoor positioning approaches in an hospital environment using sensor available on Android phones together with Wi-Fi fingerprintingand map information. The purpose is to determine the resolution of pedestrian indoor positioning and whether it is sufficient for room level accuracy. LÄS MER
