  1. 21. Towards a method for antenna impedance tailoring through shapeoptimization, with a bound on the associated cost-function

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

    Author : Cem Kesici; [2020]
    Keywords : ;

    Abstract : Over the last years, there has been an interest in designing antennas that operateat higher frequencies. In most applications, these antennas work jointly withPower Amplifiers. However, most commercial Power Amplifiers have a nonstandardoptimal load-pull impedance in their optimal operating frequencies. READ MORE

  2. 22. In Pursuit of Sustainability : Decentralized Renewable Energy Services in India

    University essay from Uppsala universitet/Industriell teknik

    Author : Max Rosvall; [2020]
    Keywords : Decentralized Renewable Energy; Technological Innovation Systems; Sustainable Transformations; Sustainable Development;

    Abstract : Based on the grand challenges of transforming the energy sector towards sustainability and harvesting the potential from decentralized solar PV, a holistic and systemic perspective is required. This study presents the case of decentralized renewable solutions in Karnataka India. READ MORE

  3. 23. LPI waveforms for AESA radar

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Andreas Sjöberg; [2020]
    Keywords : Radar LPI waveform AESA;

    Abstract : The purpose of low probability of intercept (LPI) radar is, on top of the standard requirements on a radar, to remain undetected by hostile electronic warfare (EW) systems. This can be achieved primarily by reducing the amount of radiated power in any given direction at all times and is done by transmitting longer modulated pulses that can then be compressed digitally in order to retain range resolution.

  4. 24. ADVERSARIAL ATTACKS ON FACIAL RECOGNITION SYSTEMS

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Pontus Fält; [2020]
    Keywords : ;

    Abstract : In machine learning, neural networks have shown to achieve state-of-the-art performance within image classifi€cation problems. ‘Though, recent work has brought up a threat to these high performing networks in the form of adversarial att‹acks. READ MORE

  5. 25. Reduction of streak artifacts in radial MRI using CycleGAN

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Amanda Ullvin; [2020]
    Keywords : MRI; Cardiovascular; CMR; Medical Imaging; Radial k-space sampling; Sub-Nyquist sampling; Golden Angle; GRASP; Compressed Sensing; Artificial Intelligence; Neural Network; Deep Learning; GAN; CycleGAN;

    Abstract : One way of reducing the examination time in magnetic resonance imaging (MRI) is to reduce the amount of raw data acquired, by performing so-called undersampling. Conventionally, MRI data is acquired line-by-line on a Cartesian grid. READ MORE
