  1. 1. Fast Simulations of Radio Neutrino Detectors : Using Generative Adversarial Networks and Artificial Neural Networks

    University essay from Uppsala universitet/Högenergifysik

    Author : Anton Holmberg; [2022]
    Keywords : Askaryan emission; Radio detection of neutrinos; in-ice propagation; neutrino; Generative adversarial networks; GAN; WGAN; Neural networks; NN; surrogate model; IceCube; deep learning; generative model;

    Abstract : Neutrino astronomy is expanding into the ultra-high energy (>1017eV) frontier with the use of in-ice detection of Askaryan radio emission from neutrino-induced particle showers. There are already pilot arrays for validating the technology and the next few years will see the planning and construction of IceCube-Gen2, an upgrade to the current neutrino telescope IceCube.

  2. 2. Odling av växter för naturvård i Sverige : behovsanalys och processbeskrivning

    University essay from SLU/Department of People and Society

    Author : Sofia Dahlgren; [2022]
    Keywords : Inhemska växter; naturvård; odling; kärlväxter; ängsväxter; ekologi; bevarandebiologi; biologisk mångfald; ekosystemtjänster; restaurering;

    Abstract : Förlusten av biologisk mångfald är numera ett erkänt problem över hela världen. Många forskare och organisationer har gått ut med att vi måste restaurera stora naturområden med utarmade ekosystem för att bromsa och helst vända denna trend (Balvanera et al. 2019; IUCN 2019).

  3. 3. Effects of temperature on germination and juvenile growth in Spinach (Spinacia oleracea L.)

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Gabriel von Rosen; [2022]
    Keywords : indoor farming; vertical farming; hydroponics; spinach; seed germination;

    Abstract : As the worlds urban population grows more and more every year, it becomes increasingly important that cities become more self-sufficient on food. Indoor vertical hydroponic farms offer a solution to this by placing the farm in an urban environment and growing plants in a controlled environment. READ MORE

  4. 4. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
    Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

    Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

  5. 5. Nonlinear Methods of Aerodynamic Data-driven Reduced Order Modeling

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Arvid Forsberg; [2022]
    Keywords : machine learning; aerodynamics; autoencoder; kernel transformation; principal component analysis; nonlinear; regression; modeling; surrogate model; reduced order modeling; neural network;

    Abstract : Being able to accurately approximate outputs of computationally expensive simulations for arbitrary input parameters, also called missing points estimation, is central in many different areas of research and development with applications ranging from uncertainty propagation to control system design to name a few. This project investigates the potential of kernel transformations and nonlinear autoencoders as methods of improving the accuracy of the proper orthogonal decomposition method combined with regression.
