1. 1. Assessing water balance and yields in Malawian cropping systems : maize soybean and maize Gliricidia systems resilience against climate change

   University essay from SLU/Dept. of Soil and Environment

   Author : Danila Valeriano; [2024]
   Keywords : crop modelling; APSIM; Malawi; maize; soybean; Gliricidia; agroforestry; legume intercropping; climate predictions; climate adaptation; SDSM;

   Abstract : In Malawi, maize monocultures are increasingly susceptible to extreme weather patterns, causing considerable yield reduction and heightened food insecurity for smallholder farmers dependent on rainfed subsistence agriculture. Diversifying cropping systems is crucial for ensuring yield resilience. READ MORE

3. 2. MetaStackVis: Visually-Assisted Performance Evaluation of Metamodels in Stacking Ensemble Learning

   University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

   Author : Ilya Ploshchik; [2023]
   Keywords : Visualization; interaction; metamodels; validation metrics; predicted probabilities; stacking; stacked generalization; ensemble learning; machine learning;

   Abstract : Stacking, also known as stacked generalization, is a method of ensemble learning where multiple base models are trained on the same dataset, and their predictions are used as input for one or more metamodels in an extra layer. This technique can lead to improved performance compared to single layer ensembles, but often requires a time-consuming trial-and-error process. READ MORE

4. 3. Unsupervised Online Anomaly Detection in Multivariate Time-Series

   University essay from Uppsala universitet/Datorteknik

   Author : Ludvig Segerholm; [2023]
   Keywords : unsupervised; online; anomaly detection; explainable ai; machine learning; mahalanobis distance;

   Abstract : This research aims to identify a method for unsupervised online anomaly detection in multivariate time series in dynamic systems in general and on the case study of Devwards IoT-system in particular. A requirement of the solution is its explainability, online learning and low computational expense. READ MORE

5. 4. Spectromorphological Reductions : Exploring and developing approaches for sound-based notation of live electronics

   University essay from Luleå tekniska universitet/Musik, medier och teater

   Author : Hans Lennart Jonsäll; [2023]
   Keywords : live electronics; electronic music; electroacoustic music; notation; spectromorphology; typo-morphology; Sound Notation; digital musical instruments.;

   Abstract : In this master’s thesis, a sound-based notation system is explored and developed in the composition and performance of a musical work for live electronics. My approach builds on existing systems for electroacoustic music analysis, most notably Dennis Smalley’s (1997) theory of spectromorphology and the symbolic language of Lasse Thoresen & Andreas Hedman (2007) based on Pierre Schaeffer’s typo-morphology, as well as Mattias Sköld’s (2023) adaptation of this system for composition and transcription (Sound Notation).

6. 5. Data Assimilation for Systems with Multiple Timescales

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Dan Vicente Ihanus; [2023]
   Keywords : Mathematics; Partial Differential Equations; Numerical analysis; Data assimilation; Numerical weather prediction; Ensemble Kalman Filter;

   Abstract : This text provides an overview of problems in the field of data assimilation. We explore the possibility of recreating unknown data by continuously inserting known data into certain dynamical systems, under certain regularity assumptions. READ MORE
