  1. 21. Effects of modified river cross-section geometry on hydraulic modelling performance: the slope break method

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Feixiong Qu; [2021]
    Keywords : ;

    Abstract : Remote sensing data has been widely used for large scale hydraulic modelling in the world. One of the most common ways to collect remote sensing data is by satellite. The digital elevation data observed from space is publicly accessible and covers almost all areas of the earth. However, the satellite cannot observe the river bathymetry. READ MORE

  3. 22. Remote Sensing Based Pre-Season Yellow Rust Early Warning in Oromia, Ethiopia

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Chinatsu Endo; [2021]
    Keywords : yellow rust; modeling; prediction; early warning; remote sensing; geography; geographical information systems; GIS; Agriculture and Food Sciences; Earth and Environmental Sciences;

    Abstract : Yellow rust (Puccinia striiformis f. sp. Tritici) is a crop disease caused by a fungus that regularly infects wheat and causes yield loss in Ethiopia. The disease has a significant impact on the country’s crop production, food security, health, and socioeconomic well-being. READ MORE

  4. 23. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Christine Andersson; [2021]
    Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

    Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.

  5. 24. Using remote sensing and land abandonment as a proxy for long-term human out-migration. A Case Study: Al-Hassakeh Governorate, Syria

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Berit Mohr; [2021]
    Keywords : geography; GIS; remote sensing; Syria; vegetation indices; land abandonment; Earth and Environmental Sciences;

    Abstract : The topic of human migration and displacement has become more important in recent years and will continue to do so in the following decades. Voices become louder claiming that climate change is a driving factor for increased displacement and migration. READ MORE

  6. 25. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ainahu Abdul Hamid; [2021]
    Keywords : Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Abstract : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. READ MORE
