1. Superconducting gates for InP HEMTs
Master-uppsats, KTH/Tillämpad fysikSammanfattning : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. LÄS MER
2. Hidden behind the pandemic: A study on the effects of the COVID-19 restrictions on dissent
Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskningSammanfattning : This thesis aims to address how COVID-19 restrictions affected dissent events in autocracies and electoral autocracies. To do so relies on the combination of the grievances and resource mobilization theories. LÄS MER
3. A Modular Approach to Design and Implementation of an Active GNSS Antenna
Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : This masters thesis describes the design, implementation and testing of an active antenna intended for use with global navigation satellite systems. The active antenna is composed of two major parts, a dual-band circular patch antenna and a dual-band low-noise amplifier. To streamline the design process, a modular solution was adopted. LÄS MER
4. Sjuksköterskors upplevelser av palliativ vård för vuxna patienter med invandrarbakgrund : En litteraturöversikt
Kandidat-uppsats, Jönköping University/HHJ, Avd. för omvårdnadSammanfattning : . Bakgrund: I dagens samhälle, på ett globalt nivå, möter sjuksköterskor allt oftare patienter med annan kulturell bakgrund. Att få kunskap inom olika kulturer för att kunna ge patienten i behov av palliativ vård en god och säkert vård kan inte betraktas som enkel uppgift. LÄS MER
5. Evaluation of Discrete-Time Wideband Receivers for NB-IoT
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. LÄS MER
