  1. 1. Quantifying Middle Frequency Transient Currents in Power Consuming Devices

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Alex Lundvall; Vincent Sollie; [2021]
    Keywords : ;

    Abstract : The complexity of electrical systems present in vehicles is continuously rising and the number of interconnected electrical devices is growing during the strive for optimization and reaching higher efficiency levels. Actuation of said devices have the possibility of injecting voltage and current harmonics into the system, thus negatively affecting neighbouring devices. READ MORE

  3. 2. Signal Processing for mmWave MIMO Radar

    University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Author : Óscar Faus García; [2015]
    Keywords : radar; automotive; MIMO; CW; 79 GHz; short-range radars SRR ; millimeter wave; CFAR; simulations; phase modulation; algorithms; system gain;

    Abstract : This thesis addresses the design study, implementation and analysis of signal processing algorithms for a 79 GHz millimeter-wave Phase Modulated Continuous Wave (PMCW) Multi Input Multi Output (MIMO) short range radar; performed in IMEC research institute (Leuven, Belgium). The radar system targets high resolution performance with low power consumption in order to integrate a full MIMO radar transceiver with digital processor and antennas in a compact package featuring a size of 1 cm2.

  4. 3. Ultrasound induced cavitation and resonance amplification using adaptive feedback Control System

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Vipul. vijigiri; Taraka Rama Krishna Pamidi; [2014]
    Keywords : Acoustic cavitation; optimization; FFT analysis; pure sine excitation; Sonotrode or ultrasonic horn; High intensity ultrasound; Sound pressure level SPL Acoustic pressure field; Feedback control; Master of Science Programme in Electrical Engineering with emphasis on Signal Processing Masterprogram i Elektroteknik med inriktning mot signalbehandling;

    Abstract : Acoustic cavitation in fluids using high powered ultrasound has been of great interest in industries and biomedical engineering. The need for high-intensity focused ultrasound (sound with frequencies between 20 kHz to 10 MHz) and modeling of such systems has drawn great attention in engineering. READ MORE

  5. 4. BENCHMARK OF TRIGGERED INSTRUCTION BASED COARSE GRAINED RECONFIGURABLE ARCHITECTURE FOR RADIO BASE STATION

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Yu Yang; [2014]
    Keywords : ;

    Abstract : Spatially-programmed architectures such as FPGA are among the most prevailing hardware in various application areas. However FPGA suffers from great overheads such as area, latency and power efficiency. Coarse-grained Reconfigurable Architecture (CGRA) is designed in order to compensate these disadvantages of FPGA.

  6. 5. Data Processing Algorithms in Wireless Sensor Networks får Structural Health Monitoring

    University essay from KTH/Bro- och stålbyggnad

    Author : Nigatu Mitiku Danna; Esayas Getachew Mekonnen; [2012]
    Keywords : Bridge; FFT; Modal Analysis; Monitoring; Natural Frequency; Peak Picking; Structure; Wireless Sensor.;

    Abstract : The gradual deterioration and failure of old buildings, bridges and other civil engineering structures invoked the need for Structural Health Monitoring (SHM) systems to develop a means to monitor the health of structures. Dozens of sensing, processing and monitoring mechanisms have been implemented and widely deployed with wired sensors. READ MORE
