1. 1. The active phase of Pt(110) during catalytic CO oxidation

   University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Author : Hira Qazilbash; [2024]
   Keywords : Physics and Astronomy;

   Abstract : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. READ MORE

3. 2. Audibility & Preference of DA Overload Associated with True Peak : Investigation of claims made against overload prevention

   University essay from Luleå tekniska universitet/Musik, medier och teater

   Author : Mattias Strand; [2023]
   Keywords : true peak; mastering; inter-sample; intersample; peaks; peaking; overload; digital to analog; da; loudness; clipping; truncation; square wave;

   Abstract : The conversion of audio from the digital to analog domain has the potential to result in distortion due to converter overload. This occurs because some peaks in the signal cannot be defined digitally and only become problematic during the conversion into the analog domain, exceeding the level that can be represented by the converter, causing it to overload.

4. 3. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Fabian Tidner; [2023]
   Keywords : Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

   Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

5. 4. Developing a Cost Model For Combined Offshore Farms : The Advantages of Co-Located Wind and Wave Energy

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Eva Blech; [2023]
   Keywords : Wave Energy; Floating Offshore Wind; Co-located Wind-Wave Farm; Levelized Cost of Energy; Multi-Source Offshore Farm; Vågenergi; flytande havsbaserad vindkraft; samlokaliserad vind- och vågpark; nivellerad energikostnad; havsbaserad park med flera källor;

   Abstract : Previous research has displayed that multi-source farms provide an opportunity to reduce the cost of energy and improve the energy output quality. This thesis assesses the cost competitiveness of co-located wind-wave farms, specifically floating offshore wind (FLOW) turbines and CorPower’s wave energy converters (WEC). READ MORE

6. 5. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE
