  1. 16. RF BiST för att detektera IQ-imbalanser avseende överhörningseffekter för avancerade antennsystem

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Kishore Khed; [2018]
    Keywords : Technology and Engineering;

    Abstract : Internet of Things (IoT) is a network constituted by uniquely identifiable commodity objects or devices equipped with some sensing system. To achieve high data rates required for IoT devices, a modern wireless communication system, known as Advanced Antenna Systems(AAS), leads to significant improvement, by increasing not only the data rate but also spectrum efficiency and the channel capacity.

  3. 17. Assessment of forcing mechanisms on net community production and dissolved inorganic carbon dynamics in the Southern Ocean using glider data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Schütt; [2017]
    Keywords : net community production; geography; physical geography; dissolved inorganic carbon; Southern Ocean; Earth and Environmental Sciences;

    Abstract : In the Subantarctic Zone of the Southern Ocean, a combination of physical forcings, chemical solubility and biological fixation is controlling the carbon uptake and thus the role the Southern Ocean is playing in the remediation of global climate change. Therefore, it is necessary to understand the mechanisms controlling oceanic carbon budgets and to quantify biological uptake rates to make reliable future climate predictions. READ MORE

  4. 18. Microbes that never sleep : A multidisciplinary study of the antibiotic resistance management in Sweden

    University essay from Södertörns högskola/Institutionen för naturvetenskap, miljö och teknik

    Author : Vendela Bergfeldt; [2016]
    Keywords : Antibiotic resistance; antibiotics; risk theory; infectious disease control;

    Abstract : The hypotheses of this study are that reduction and rational usage of antibiotics reduces development of antibiotic resistance. In Sweden, the trends do not follow this pattern. READ MORE

  5. 19. Numerical analysis of Urea-SCR sprays under cross-flow conditions

    University essay from KTH/Mekanik

    Author : Jakob Heide; [2016]
    Keywords : Lagrangian Particle Tracking; Selective Catalyst Reduction; droplet;

    Abstract : The mixing and evaporation of Diesel Exhaust Fluid (DEF) inside an Urea Selective Catalyst Reduction (SCR) chamber has been numerically investigated. The first task in this work has been to first look into the numerical framework and assess the models available in a commercial CFD software (ANSYS Fluent 14.5). READ MORE

  6. 20. Hydraulic Characterization of Diesel Engine Single-Hole Injectors

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Javier Arco Sola; [2015]
    Keywords : ;

    Abstract : Due to world trend on the emission regulations and greater demand of fuel economy,the research on advanced diesel injector designs is a key factor for the next generation diesel engines. For that reason, it is well established that understanding the effects of the nozzle geometry on the spray development, fuel-air mixing, combustion and pollutants formation is of crucial importance to achieve these goals.
