  1. 1. Designing a communication controller for a wireless sensor network : Practical considerations and comparisons

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

    Author : Frej Larssen; Axel Karlsson; [2023]
    Keywords : Wireless sensor networks; IoT; LTE-M; Comparison; Trådlösa sensornätverk; IoT; LTE-M; Jämförelse;

    Abstract : As the use of Internet of Things (IoT) devices increases, so does the number of available hardware platforms. Today there exists a broad range of hardware components that could be used to develop an IoT product and selecting the right ones is a difficult task. READ MORE

  3. 2. Automated Attendance System : Recognition System Based on Facial Features

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Ganesh Sreekhyath Nelaturi; Venkata Sai Poliki; [2022]
    Keywords : Camera Module; MATLAB; Python; Raspberry Pi; Face recognition;

    Abstract : Consider a situation where you need to identify each and every person in a room and categorize each of the persons as present or absent. To mark the presence of hundreds of people in a room takes a lot of time, which means you can eventually be left out with less time to explain the main aim of that meeting, class, or some other things.

  4. 3. Calculating Minimum Detectable Activity for a moving scintillator detector using real-time speed measurement : Implementing a monitoring system to improve accuracy of surface contamination measurement systems

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

    Author : Artur Amcoff; Oscar Persson; [2021]
    Keywords : Minimum Detectable Activity MDA ; Surface contamination; ISO 11929; Alpha α radiation; Beta β radiation; Detection limit; Counting efficiency; Minsta detekterbara aktivitet; Ytkontaminering; ISO 11929; Alfa α strålning; Beta β strålning; Detektionsgräns; Radioaktiv mäteffektivitet;

    Abstract : Surface contamination occurs in nuclear facilities, something that is important to detect easily and efficiently. Using today’s methods to detect nuclear surface contamination may cause certain inconsistencies as the human operator is solely trusted to keep the detector at the correct distance and move it at the correct speed.

  5. 4. Automatic Torque Control for Bicycle Driven Brushless DC (BLDC) Generator

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Luke Müller; Kasper Sjöström; [2021]
    Keywords : BLDC; brushless dc generator; brushless dc motor; JFET; Torque; Generator Torque; Automatic Torque Control; Field Effect Transistor; PWM;

    Abstract : This work was carried out on behalf of Science Safari. Science Safari wants to create a product that facilitates the understanding of how much physical work is required to create electrical energy. This is done by cranking the pedals of a bicycle. READ MORE

  6. 5. Estimating energy consumption of Wifi transceiver circuits on a single board computer

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

    Author : Frida Mattsson; [2021]
    Keywords : Transceiver circuit; 802.11; energy consumption; software profiling; single-board computer; Raspberry Pi; Transceiver; 802.11; energikonsumtion; mjukvaruprofilering; enkortsdator; Raspberry Pi;

    Abstract : This work comprises an approximation of the energy consumption of the transceiver circuit in a single board computer. Single board computers, such as the Raspberry Pi 4 Model B that is used here, are usually cheap and therefore more accessible. READ MORE
