  1. 1. Control system and simplified timesynchronization for heterogenous IoT systems with medium time requirements

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Jemma Touma; Simon Hejdenberg; [2024]
    Nyckelord :Internet of Things; time synchronization; wireless sensor networks; network time protocol; Android; Bluetooth; WiFi Direct;

    Sammanfattning : The company QTPIE conducts research on drivers and their unconscious reactions when driving. To help, they use smart devices that today must be individually handled at the start and end of a run, and have individually set timestamps, which can lead to differences between the units when data is entered and collation of the units' data after a run.

  3. 2. Wi-Fi fingerprinting as a mean to measure building occupancy : A case study in an office environment

    Master-uppsats, KTH/Transportplanering

    Författare :Johan Bexhorn; Karl Kvarnefalk; [2023]
    Nyckelord :Wi-Fi tracking systems; Wi-Fi fingerprinting; footfall analytics;

    Sammanfattning : The task of collecting visitor data in an indoor environment and therein determining the occupancy of a building is an extensive task. Conventional methods are expensive, time-consuming, and often lack the ability to produce data in longer time series. Further, they often require disruption of the studied area as equipment must be deployed. LÄS MER

  4. 3. Evaluation of Cyber-Attacks in Networked Control Systems

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Teja Kedar Vadde Hulgesh; [2023]
    Nyckelord :;

    Sammanfattning : Networked Control Systems (NCS) form an essential role in numerous critical infrastructures, including water distribution plants, water treatment plants, electric power grids, and power transmission networks. NCS employ a communication network to share data between the plant and the controller.

  5. 4. Design and Evaluation of a logging system in a power-constrained environment

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Morgan Adamsson; [2023]
    Nyckelord :Low power; logging; embedded systems; power supply; Bluetooth Low Energy; WiFi; flash memory; Låg effekt; loggning; inbyggda system; strömförsörjning; Bluetooth Low Energy; WiFi; flashminne;

    Sammanfattning : Logging plays a crucial role in debugging endeavors, assisting technicians in identifying errors and improving the overall sustainability of electrical systems. This thesis focuses on integrating local logging capabilities into the Balise Transmission Module (BTM), a legacy control system that lacks such features. LÄS MER

  7. 5. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

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

    Författare :Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
    Nyckelord :Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

    Sammanfattning : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. LÄS MER
