  1. 1. Backpack-based inertial navigation and LiDAR mapping in forest environments

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tjernqvist Mattias; [2017]
    Keywords : lidar; gnss; ins; mls; forest;

    Abstract : Creating 3D models of our surrounding world has seen a rapid increase in research and development over the last few years. A common method is to use laser scanners. Mapping is done either by ground based systems or airborne systems. READ MORE

  3. 2. Atmospheric Particles in Kermanshah, Iran

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

    Author : Rebecka Häggström; [2017]
    Keywords : aerosols; aerosol technology; SMPS; soot concentrations; dust; Iran; Kermanshah; PSAP; airborne particles; Technology and Engineering; Physics and Astronomy; Earth and Environmental Sciences;

    Abstract : No measurements of airborne particles have been done in Iran previously. Starting characterization of aerosol particles in a completely new geographical area, a suitable and important measurement parameter is the aerosol particle number size distribution. This can be used to indirectly infer climate- and health effects of the particles. READ MORE

  4. 3. Size-dependent airborne particle emissions from ship traffic

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

    Author : Fredrik Mattsson; [2016]
    Keywords : Aerosol particle; shipping; emission; health effect; particle number concentration; particle number size distribution; Physics and Astronomy;

    Abstract : Most aerosol particles emitted from shipping affect the climate by counteracting the greenhouse effect. Although, this masks the warming effect of greenhouse gases, aerosol particles also have a negative health effects, and therefore emissions need to be reduced. READ MORE

  5. 4. Airborne

    University essay from Lunds universitet/Industridesign

    Author : Kornelia Knutson; [2015]
    Keywords : Arts and Architecture; Technology and Engineering;

    Abstract : Airborne diseases are spread when droplets containing pathogens, viruses and/or bacteria, are expelled into the air due to coughing, sneezing or talking. These droplets, or aerosols, can remain suspended in the air for quite some time in contained environments. READ MORE

  6. 5. Is there new particle formation in the marine boundary layer of the North Sea?

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Natalia Kelbus; [2014]
    Keywords : Geography; Physical Geography; aerosol particles; new particle formation; nucleation; particle size distribution; NanoMap; Science General; Earth and Environmental Sciences;

    Abstract : The effect of aerosol particles on climate and the human health emphasizes the necessity to focus on the research about aerosol particles. Aerosol particles emitted due to anthropogenic activities increase the scattering and absorption of solar radiation in the atmosphere which leads to an increased cooling of the climate (direct effect).
