  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. Study on Low Voltage Power Electronics Used for Actuator Control

    University essay from Linköpings universitet/Datorteknik

    Author : Oskar Kleback; [2017]
    Keywords : PI-controller; controller; Actuator;

    Abstract : The aim of this thesis is to understand the current implementation, how different hardware and output frequency affects the hydraulic actuators in the current platform and Then an improve the controller should be presented. This needs to be both faster then the current controller and should not use more CPU recurses then necessary. READ MORE

  4. 3. Multi-buoy Wave Energy Converter : Electrical Power Smoothening from Array Configuration

    University essay from Uppsala universitet/Elektricitetslära

    Author : Elisabet Jansson; [2016]
    Keywords : wave energy; wave power; wave energy converter; electrical power; power smoothening; wave energy converter array;

    Abstract : This master thesis is done within the Energy Systems Engineering program at Uppsala University and performed for CorPower Ocean. Wave energy converters (WECs) are devices that utilize ocean waves for generation of electricity. The WEC developed by CorPower Ocean is small and intended to be deployed in an array. READ MORE

    University essay from Elektroniksystem; Tekniska högskolan

    Author : Johan Lindeberg; [2014]
    Keywords : Analog to Digital Converter ADC ; Cyclic; Algorithmic; Incremental; Capacitor mismatch; Compensation;

    Abstract : The objective of this Master's thesis was to design and implement a low power Analog to Digital Converter (ADC) used for sensor measurements. In the complete measurement unit, in which the ADC is part of, different sensors will be measured. READ MORE

  6. 5. Transient Control of SIDI-Engine with VGT and VVT

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Erik Klingborg; [2012]
    Keywords : ;

    Abstract : Today's development of spark ignited (SI) engines is to a large extent focused on downsizing, i.e where a large naturally aspirated engine is replaced with a smaller turbocharged engine with the same output power. READ MORE
