  1. 1. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Martin Larsson; [2019]
    Keywords : soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

    Abstract : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. READ MORE

  2. 2. A Monte Carlo simulation study of collimators for a high-spatial-resolution Gamma Emission Tomography instrument

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Anastasios Anastasiadis; [2019]
    Keywords : ;

    Abstract : The present master thesis concerns a study of collimator designs for a high-spatial-resolution Gamma Emission Tomography (GET) instrument for used fuels utilizing Monte Carlo simulation codes. Designing a collimator for this purpose is a multilateral process that requires many interconnected and conflicting objectives to be taken into consideration. READ MORE

  3. 3. Low-dispersive Leaky-wave Antennas: A Viable Approach for Fifth Generation (5G) mmWave Base Station Antennas

    University essay from KTH/Elektroteknisk teori och konstruktion

    Author : Oskar Dahlberg; [2019]
    Keywords : ;

    Abstract : In this work, a method to achieve reduced beam-squint in fully metallic leaky-wave antennas is proposed and its applicability for high frequency, high gain, base station antennas in future communication networks is indicated. The antenna is built in gap waveguide technology, where the fundamental mode is allowed to leak by removal of one of the waveguide walls. READ MORE

  4. 4. Hydrological and chloride transport processes in a small catchment of the Norrström Basin : a MIKE SHE modelling approach

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Zhuhuan Liu; Chen Zhou; [2019]
    Keywords : MIKE SHE; Hydrological Modelling; Kringlan; Water Balance; Particle Tracking;

    Abstract : Water is ubiquitous on our planet and constitutes a vital part of ecosystems. It supports the life of all beings on the earth while simultaneously evokes water-related issues such as water shortage, water contamination. As UN advocates, a globally shared blueprint for available clean water is depicted in Sustainable Development Goals (SDGs). READ MORE

  5. 5. Next Generation Automotive Sun Visor : Product Development

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Erik Torehov Ronnevik; [2019]
    Keywords : Sun visor; Product development; Solskydd; produktutveckling;

    Abstract : The main purpose of the sun visor is to prevent the driver and passengers to get blinded by the sunlight. It is essential that the sun visor is not blocking the view and that the driver has a clear line of sight so that collisions can be prevented. READ MORE
