  1. 1. Nonlinear effects and predictions in advanced antenna systems in 5G Distortion Effects in 5G

    University essay from Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Author : Altahra Mohammed; [2019]
    Keywords : PA; DPD; Active load-pull; Calibration.;

    Abstract : In the next-generation wireless cellular communication systems known as 5G, radio equipment will be deployed in several frequency bands, among them is the millimeter wave bands (26 - 40 GHz). The use of these high frequencies can help to mitigate the limited spectrum problem and higher data rates can be achieved [2] . READ MORE

  3. 2. Non-linear electronic entanglement witness based on current cross correlations

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Author : Samuel Luc M Vermeulen; [2017]
    Keywords : physics; quantum information; entanglement; entanglement witness; Physics and Astronomy;

    Abstract : Demonstration of entanglements of mobile electrons in solid state conductors using minimal entanglement linear witness from electrical current correlations has been given. However, detection of maximally entangled states and some mixed states is lacking if the witness is based on two cross correlation measurements only. READ MORE

  4. 3. Simulation and Mathematical Analysis of a Task Partitioning Model of a Colony of Ants

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Viktor Södergren; [2016]
    Keywords : Social insects; Ants; Task partitioning; Self-organization; Nonlinear operators; Dynamical systems; Fixed point theorems;

    Abstract : In this thesis we study a mathematical model that describes task partitioning in a colony of ants. This process of self-organization is modeled by a nonlinear coupled system of rst order autonomous ordinary dierential equations. We discuss how this system of equations can be derived based on the behavior of ants in a colony. READ MORE

  5. 4. Improving Low Voltage Ride-Through Requirements (LVRT) Based on Hybrid PMU, Conventional Measurements in Wind Power Systems

    University essay from Avdelningen för fysik och elektroteknik

    Author : Chinedum Ekechukwu; [2014]
    Keywords : State Estimation; Power Systems; Unscented Kalman Filters; Phasor Measurement Units;

    Abstract : Previously, conventional state estimation techniques have been used for state estimation in power systems. These conventional methods are based on steady state models. As a result of this, power system dynamics during disturbances or transient conditions are not adequately captured. READ MORE

  6. 5. Control of temperature using fuzzy system tehnique

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Elif Ceylan Kolbasi; [2013]
    Keywords : ;

    Abstract : Fuzzy control is based on fuzzy logic. A logical system that is much closer in spirit to human thinking and natural language than traditional crisp logical systems. The fuzzy logic variables are not described as true or false values. Instead values range in degree between 0-1,true-false or yes-no. READ MORE
