1. 21. Data analysis for predicting air pollutant concentration in Smart city Uppsala

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Varun Noorani Subramanian; [2016]
   Keywords : ;

   Abstract : Pollution concentrations in urban areas are primarily from vehicular exhaust, factories, and small scale industries. Recent studies conducted by the Swedish Meteorological and Hydrological Institute (SMHI) says that 3000-5000 premature deaths [2] occur every year as a result of inhaling a high level of pollution concentrations like PM10, PM2.

3. 22. Zinc tolerance of freshwater diatoms isolated from sites with zinc pollution; and pH effect on zinc toxicity

   University essay from SLU/Dept. of Aquatic Sciences and Assessment

   Author : Amanda Hedenborg; [2016]
   Keywords : freshwater diatoms; indicator for metal pollution; zinc pollution; pH; malformations;

   Abstract : The aim with this study was to observe the zinc (Zn), tolerance for different strains isolated from sites with Zn pollution and to observe if lower pH decreases the Zn toxicity. Another aim was to see if malformations could be an indicator for Zn pollution. Zn is found naturally in the bedrock, sediment and waterbodies. READ MORE

4. 23. Change Detection in Stockholm between 1986 and 2006 using SPOT Multispectral and Panchromatic Data

   University essay from KTH/Geodesi och geoinformatik

   Author : Ann-Mari Skrifvare; [2013]
   Keywords : change detection; remote sensing;

   Abstract : With an increasing urban population in Sweden, expecting to reach 90% by 2050 (UN World Urbanization prospects, The 2011 Revision), this high level of urban population put pressure on functioning infrastructure, sufficient housing and need to monitor the environmental effects such as pollution and the effects of land use change. Stockholm County currently holds 22% of the population and accounts for nearly half of the urban growth in Sweden (Svensk Handelskammare). READ MORE

5. 24. Implementation and evaluation of two change detection-methods applied to multivariate Gaussian data streams

   University essay from Lunds universitet/Matematisk statistik

   Author : Julia Petersson; [2012]
   Keywords : Change detection; sliding windows; Kullback-Leibler distance; data streams; Bayesian parameter estimation; Kdq-tree; Bootstrapping; Mathematics and Statistics;

   Abstract : Different types of data streams, time series, are generated in systems and collected in information bases all over the world. One may have data streams of temperatures, air pollution, share prices, traffic demand for networks or strength of the emitted radiation from a power plant. READ MORE

6. 25. Assessment of Pollution Levels Resulting from Biomass Gasification

   University essay from KTH/Kraft- och värmeteknologi

   Author : Emmanuel Menya; [2012]
   Keywords : producer gas cooling; condensate; PAHs; BTEX; CGCMSD; carcinogenic; toxic; downdraft gasifier;

   Abstract : Today the large scale introduction of biomass gasification is hampered by health, safety and environmental issues which present a major barrier in the deployment of this technology. The condensate in particular resulting from producer gas cooling before use in gas engines is highly toxic and carcinogenic which, if not adequately controlled, can lead to detrimental impacts on human health and the environment.
