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

   University essay from Linköpings universitet/Statistik och maskininlärning

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

   Abstract : 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. READ MORE

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

   University essay from Linköpings universitet/Statistik och maskininlärning

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

   Abstract : 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. READ MORE

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

   University essay from Linköpings universitet/Tema Miljöförändring

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

   Abstract : 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. READ MORE
