1. 21. Atmospheric soot particle transformation from urban to rural

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

   Author : Fredrik Johansson; [2018]
   Keywords : Aerosol; soot; atmosphere; Physics and Astronomy; Earth and Environmental Sciences;

   Abstract : The main objective of this work was to investigate if there is a contribution of aerosol from the urban region of Copenhagen at the rural station Vavihill. This was done by analyzing measurement data between 1st of January and the 28th of February 2013 measured with a Dierential Mobility Particle Sizer (DMPS), Soot Particle Aerosol Mass Spectrometer (SP-AMS), a Cloud Condensation Nuclei Counter (CCNC) and a NOx-analyzer.

3. 22. Evaluation of Supervised Machine LearningAlgorithms for Detecting Anomalies in Vehicle’s Off-Board Sensor Data

   University essay from Högskolan Dalarna/Mikrodataanalys

   Author : Nor-Ul Wahab; [2018]
   Keywords : Anomaly detection; rule-based; one class support vector machine; k-nearest neighbor; random forest; confusion matrix; accuracy; precision; recall; F1-score;

   Abstract : A diesel particulate filter (DPF) is designed to physically remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Frequently replacing DPF is a waste of resource and waiting for full utilization is risky and very costly, so, what is the optimal time/milage to change DPF? Answering this question is very difficult without knowing when the DPF is changed in a vehicle. READ MORE

4. 23. Image analysis to estimate the fractal dimension of soot aggregates

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

   Author : Adrian Roth; [2018]
   Keywords : soot; aggregates; fractal; dimension; image; analysis; Technology and Engineering;

   Abstract : Examensarbetet har utvecklat en metod för att estimera den fraktala dimensionen från Transmissions Elektron Mikroskop (TEM) bilder av sot aggregat som skapats med hjälp av en mini-CAST sotgenerator. Det är ett underbestämt problem att estimera den fraktala dimensionen, en 3D egenskap, från 2D bilder. READ MORE

5. 24. Fine particle emissions from biomass cookstoves : Evaluation of a new laboratory setup and comparison of three appliances

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Natxo Garcìa Lòpez; [2017]
   Keywords : Particulate matter emissions; cookstoves; gravimetric measurements; soot and salt particles; SMPS.;

   Abstract : It is estimated that around three billion people globally rely on traditional usage of biomass to cover their daily energy needs, which causes health and social inequality problems and contributes to global warming. Thus, the study of particle emissions from cookstoves provides important information that can help improve global welfare. READ MORE

6. 25. Investigation of scattering of soot with a three-wavelength integrating nephelometer

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

   Author : Maj Blomdell; [2017]
   Keywords : Soot particles; aerosols; combustion; integrating nephelometer; scattering; light; LED s; Physics and Astronomy;

   Abstract : Soot particles are one of the major contributors to climate change and global warming, mostly due to their absorbing effect. It is of great interest to gain better knowledge about soot particles optical properties, since there are great uncertainty how they affect the atmosphere. READ MORE
