1. 1. Quantifying nitrogen oxides and ammonia via frequency modulation in gas sensors

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Marcos Freitas Mourao dos Santos; [2021]
   Nyckelord :Nitrogen oxides; nox; ammonia; sic-fet; PLSR; quantification;

   Sammanfattning : The use of Silicon Carbide Field Effect Transistor (SiC-FET) sensors in cyclic operation is a proven way to quantify different gases. The standard workflow involves extracting shape-defining features such as averages and slopes of the sensor signal. LÄS MER

3. 2. Investigation and forecasting drift component of a gas sensor

   Master-uppsats, Linköpings universitet/Statistik och maskininlärning

   Författare :Farhana Chowdhury Tondra; [2021]
   Nyckelord :Time series analysis; Forecasting; ARIMA; LSTM; Sensor; SiC-FET; ADF test; Stochastic Trend; Deterministic Trend; Sensor Drift;

   Sammanfattning : Chemical sensor based systems that are used for detection, identification, or quantification of various gases are very complex in nature. Sensor response data collected as a multivariate time series signals encounters gradual change of the sensor characteristics(known as sensor drift) due to several reasons. LÄS MER

4. 3. Methods of measuring GHG fluxes at a full-scale Swedish WWTP: : A focus on nitrous oxide, methane and carbon dioxide in the SHARON treatment

   Kandidat-uppsats, Linköpings universitet/Tema Miljöförändring

   Författare :Sjögren Jimmy; Enhäll Elin; [2017]
   Nyckelord :Wastewater treatment; SHARON; nitrious oxide; methane; carbon dioxide; greenhouse gas emission; flux chamber; gas sensors;

   Sammanfattning : The Stable high rate ammonia removal over nitrite (SHARON) at Nykvarnsverket in Linköping is a relatively new kind of biological treatment. Fluxes of nitrous oxide (N2O) has not been fully mapped at Nykvarnsverket and additional efforts are needed for increased knowledge about possible emissions. LÄS MER
