3. 12. Modelling rare events using non-parametric machine learning classifiers - Under what circumstances are support vector machines preferable to conventional parametric classifiers?

   Kandidat-uppsats, Göteborgs universitet/Institutionen för nationalekonomi med statistik

   Författare :Lukas Ma; [2021-04-06]
   Nyckelord :;

   Sammanfattning : Rare event modelling is an important topic in quantitative social science research. However, despite the fact that traditional classifiers based upon general linear models (GLM) might lead to biased results, little attention in the social science community is devoted to methodological studies aimed at alleviating such bias, even fewer of them have considered the use of machine learning methods to tackle analytical problems imposed by rare events.

4. 13. Spatio-temporal drought characteristics in the Limpopo basin from 1918 to 2018 - A case study based on analysis of the Standardized Precipitation Evaporation Index (SPEI)

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Sandra Domingos Sambo; [2021]
   Nyckelord :rdought; Standardized Precipitation Evapotranspiration Index; Limpopo River basin; Normalized difference vegetation index; Mann-Kendall Test; Correlation analysis; Earth and Environmental Sciences;

   Sammanfattning : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. LÄS MER

5. 14. Classifying Heart Rate Variability Data using Multitaper Spectrum Analysis

   Kandidat-uppsats, Lunds universitet/Matematisk statistik

   Författare :Heidi Mach; [2021]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : Heart rate variability (HRV) is the variation between two consecutive heartbeats. The irregular variability in this interval can indicate different health issues such as stress. The goal of this project is to correctly classify if a HRV signal comes from a resting state or a state which is affected by stress related stimuli. LÄS MER

7. 15. Urban infrastructure inundation risk from permanent sea-level rise scenarios in London (UK), Bangkok (Thailand) and Mumbai (India): A comparative analysis

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Shawn Pace; [2021]
   Nyckelord :Geography; GIS; Climate Change; Sea-Level Rise; Urban Infrastructure; DEM; London; Mumbai; Bangkok; Earth and Environmental Sciences;

   Sammanfattning : Due to anthropogenically created climate change, global cities are facing inundation by rising sea levels. This study aimed to fill knowledge gaps in understanding the exposure of urban infrastructure such as roads, railways, buildings and parks to sea-level rise (SLR) scenarios, and how this would affect local populations.
