  1. 11. Automatic overcurrent and leakage current sensing in multiple channel NMES systems

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

    Author : Malin Otter; Bashar Jamal Pati; [2023]
    Keywords : Neuromuscular Electrical Stimulation; Current monitoring; Overcurrent sensing; Leakage current sensing; Embedded systems; Instrumentation amplifier; Neuromuskulär elektrisk stimulering; Strömmätning; Överström detektering; Läckström detektering; Inbyggda system; Instrumentförstärkare;

    Abstract : This report presents the development, implementation, and testing of a current monitor system that is specifically developed for testing a neuromuscular electrical stimulation system (NMES). The NMES system, developed by KTH and its academic and industrial partners Karolinska institute and Matrix Muscle Support, incorporates advanced features aimed at preventing cardiovascular diseases.

  3. 12. Circuit design and hardware implementation of an analog synthesizer

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Olle Murhed; [2023]
    Keywords : synthesizer; analogue; circuit design; sound; sound synthesis; oscillator; VCO; filter; amplifier; sequencer; control voltage; breadboard;

    Abstract : Since the heyday of analogue synthesizers in the 70's, they have largely been replaced by digital hardware and software synthesizers. However, in recent years, there has been a revival in analogue designs, possibly due to its ``warmer" sound. READ MORE

  4. 13. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    University essay from KTH/Tillämpad fysik

    Author : Berkay Efilti; [2023]
    Keywords : Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Abstract : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  5. 14. Climate security: How is the United Nations responding to climate change as a source of insecurity and a hindrance to sustainable development in Sudan?

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nahom Kubrom; [2023]
    Keywords : Armed conflict; Climate security; Human security; Sudan; Sustainable Development; United Nations;

    Abstract : Climate security is a subject that focuses on the relationship between climate change and security. Climate security is a subject that supports the notion that climate change is amplifying existing security threats as climate change is having negative impacts on societies, the natural environment, and development which worsen the situation, especially in regions that already experiencing major challenges.

  6. 15. Current-Mode Class D Power Amplifier for 2.4GHz Wi-Fi

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

    Author : Yann Jean Michael Pirot; [2023]
    Keywords : Power Amplifier; Wifi; Digital Power Amplfier; Class D; RFIC; Analogue; Effektförstärkare; Wifi; digital förstärkare; klass D; analog;

    Abstract : Modern wireless communication techniques employed in the Wi-Fi® protocol, such as orthogonal frequency-division multiplexing exhibit analogue signals with high peak-to-average power ratio. Therefore, power amplifiers for Wi-Fi suffer from low efficiency when operating in back-off mode, away from their maximum efficiency at peak power. READ MORE
