1. Generating Extreme Value Distributions in Finance using Generative Adversarial Networks
Master-uppsats, KTH/Matematik (Avd.)Sammanfattning : This thesis aims to develop a new model for stress-testing financial portfolios using Extreme Value Theory (EVT) and General Adversarial Networks (GANs). The current practice of risk management relies on mathematical or historical models, such as Value-at-Risk and expected shortfall. LÄS MER
2. Water quality and organic matter linkages in waters draining arable fields
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. LÄS MER
3. Grouping Similar Bug Reports from Crash Dumps with Unsupervised Learning
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Quality software usually means high reliability, which in turn has two main components; the software should provide correctness, which means it should perform the specified task, and robustness in the sense that it should be able to manage unexpected situations. In other words, reliable systems are systems without bugs. LÄS MER
4. The role of agricultural drainage in controlling the effectiveness of two-stage ditches in Sweden
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Increased agricultural activities are causing eutrophication in downstream water bodies. To mitigate nutrient leaching from cropland, various in-field and edge-of-field practices have been implemented. LÄS MER
5. Reconstructing Weathering and Climate Trends on Loess Deposits in NW France Using XRF Analysis
Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Analyzing climate changes by loess sediment deposits formed after the last glacial maximum gives us information about how the environment was dynamically before humans physically could record climate changes. Sampling and analyzing loess from different places in the world give us a more reliable view of when events and changes in climate took place. LÄS MER
