1. 1. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Lone Mokkenstorm; [2021]
   Keywords : Physical Geography; Ecosystem Analysis; Early Warning; Riverine Floods; Humanitarian Work; Impact-based Forecasting; Malawi; Earth and Environmental Sciences;

   Abstract : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.

3. 2. Prioritising biochar application to arable land in Sweden : A spatial multi-criteria analysis

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Fabian Osslund; [2020]
   Keywords : Biochar; Spatial multi-criteria analysis; GIS; Agriculture; Soil enhancement; Biochar volume potential;

   Abstract : Biochar, the solid product of thermal conversion of biomass with little or no available air, is acknowledged as a carbon dioxide removal technique and soil enhancer among other applications. Its potential soil enhancing properties consists of increased water and nutrient holding capacities, liming effects and sorption of pollutants. READ MORE

4. 3. Time series analysis for spring barley phenology monitoring using Sentinel 2 – A case study of Southern-central Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Pavlos Aslanis; [2020]
   Keywords : spring barley; crop phenology; crop growth stages; TIMESAT; double logistic; threshold optimization; Sentinel 2; Earth and Environmental Sciences;

   Abstract : Monitoring crop phenology at parcel scale aligns with the concept of precision agriculture (PA) and can provide invaluable information to agronomic management systems. Satellite time series data are commonly deployed for detecting crop growth stages, while the recent advancements in remote sensing (RS) technologies such as the launch of Sentinel 2 (S2) are providing unprecedented opportunities for crop monitoring.

5. 4. Spatial resolution threshold in layers and red jungle fowls : are there differences due to light intensity or light spectra?

   University essay from SLU/Dept. of Animal Environment and Health

   Author : Pauline Annerstedt; [2018]
   Keywords : spatial resolution threshold; layer; red jungle fowls; visual acuity;

   Abstract : The domestic fowl (Gallus gallus domesticus) originates from the forests in South-east Asia. It may be correct to assume that the visual system of the domestic fowl is still adapted to light that is filtered through the green forest canopy. READ MORE

6. 5. Probabilistic Analysis of Brake Noise : A Hierarchical Multi-fidelity Statistical Approach

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Sreedhar Venkatesan; Hariprasad Banglore Hanumantha Raju; [2018]
   Keywords : Uncertainty and variability; probabilistic analysis; hierarchicalmultifidelity statistical approach; probability of design failure; creep groan;

   Abstract : Computer Aided Engineering driven analysis is gaining grounds in automotive industry. Prediction of brake noise using CAE techniques has become populardue to its overall low cost as compared to physical testing. READ MORE
