  1. 1. Antenna Design and Link Performance Verification of Antennas for 5G mmWave Handheld Devices

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

    Author : Vinodhini Mylai Chandrasekaran; Nikhila Chinnayanapalli Ravi; [2022]
    Keywords : Antenna Design; mmWave frequency; 5G; FEKO; Technology and Engineering;

    Abstract : The purpose of the thesis is to design a new antenna system and to verify its link performance in 5G FR2 mmWave frequency for handheld devices to enable cellular communication. The main objective is to design an antenna primarily at 28GHz and 39GHz to enhance spectrum efficiency, along with improved transmission data rates, enabling new cases like Augmented Reality (AR), Virtual Reality (VR) and many more such applications.

  2. 2. Forecasting Price Direction Using Different Sampling Methods

    University essay from KTH/Matematik (Avd.)

    Author : Niklas Mannerskog; [2021]
    Keywords : Applied mathematics; sampling methods; scaling laws; foreign exchange rates; futures; price direction; directional change; Tillämpad matematik; samplingsmetoder; skallagar; valutapar; terminer; prisriktning; directional change;

    Abstract : To extract usable information from financial data the prices of financial instruments must be summarized in an efficient manner. Typically price quotes are sampled at discrete and equidistant points in time to create a time series of prices at fixed times. READ MORE

  3. 3. Omnidirectional Quadruped Robot

    University essay from KTH/Mekatronik

    Author : Samuel Stenow; Simon Lindenfors; [2021]
    Keywords : Mechatronics; Robotics; Quadruped robot; Omnidirectional robot; Mekatronik; Robotar; Fyrbenta robotar; Multidirektionell robot;

    Abstract : There are a lot of quadruped robots in the world, but few are omnidirectional. Therefore this thesis describes the production and design process of such a robot. Examining earlier quadruped robots determined that a central microcontroller is required to control it, and servo motors are used to power the robots joints. READ MORE

  4. 4. Simulation of birefringence effects for high-energy neutrino detectors

    University essay from Uppsala universitet/Högenergifysik

    Author : Nils Heyer; [2021]
    Keywords : astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Abstract : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. READ MORE

  5. 5. Influence of land cover changes on organic carbon and organic nitrogen concentrations in Swedish rivers

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Julia Iwan; [2021]
    Keywords : Total Organic Carbon TOC ; Total Organic Nitrogen TON ; Land Cover Change; Sweden; WaterBase; Earth and Environmental Sciences;

    Abstract : There is increasing pressure on freshwater systems due to excessive nutrient loading by anthropogenic sources. In Sweden, freshwaters have become browner due to increasing exports of organic matter from soils into streams, rivers, and lakes. READ MORE
