1. 16. An Ensemble of Difference: : Understanding(s) of Participant Experiences and Learning in a Heterogenous Adult Community Drama Class of First and Second Language Speakers in Sweden

   Master-uppsats, Stockholms universitet/Institutionen för pedagogik och didaktik

   Författare :Julia Ouellette-Seymour; [2023]
   Nyckelord :Adult Education; Lifelong Learning; Drama in Education; Drama in L2; Applied Drama; Adult Learning Education; Applied Theatre; Language Learning; Community Drama; Non-formal Education; Migrant; Integration; Cultural Learning; Heterogenous Learning; SLA; Ethnographic Case Study; Vygotsky; Pragmatism;

   Sammanfattning : This case study research aimed to explore, understand, and compare the experiences of individuals participating in a heterogeneous adult community drama class in Central Sweden. Drawing from classical pragmatism and employing a conceptual framework rooted in sociocultural theory, the study utilized semi-structured interviews, open-questionnaire responses, and participant observations to collect data which was analyzed through reflexive thematic analysis.

3. 17. Evaluating machine learning models for time series forecasting in smart buildings

   M1-uppsats, KTH/Hälsoinformatik och logistik

   Författare :Sarugan Balachandran; Diego Perez Legrand; [2023]
   Nyckelord :Machine learning; supervised learning; time series forecasting; neural networks; LSTM; En- semble LSTM; AT-LSTM; ARIMA; XGBoost; Maskininlärning; övervakad inlärning; tidsserie-prognostisering; neurala nätverk; LSTM; En- semble LSTM; AT-LSTM; ARIMA; XGBoost;

   Sammanfattning : Temperature regulation in buildings can be tricky and expensive. A common problem when heating buildings is that an unnecessary amount of energy is supplied. This waste of energy is often caused by a faulty regulation system. LÄS MER

4. 18. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

   Författare :Kevin Coleman; [2023]
   Nyckelord :Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

   Sammanfattning : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. LÄS MER

5. 19. A Comparative Analysis of Decision Tree Models in Identifying Landslide Susceptibility and Type Classification

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

   Författare :Levi Jan Zuiverloon; [2023]
   Nyckelord :Landslides; landslide susceptibility mapping; Random Forest; Extreme Gradient Boosting; machine learning models; multiclass classification; binary classification; risk assessment; mitigation strategies; Italy; Aosta Valley; infrastructure vulnerability; supervised learning algorithms; Earth and Environmental Sciences;

   Sammanfattning : Landslides pose a significant risk to human life and infrastructure, especially in Italy, which has a high frequency of landslide occurrences. To mitigate these hazards, Landslide Susceptibility Mapping (LSM) is crucial for identifying risk areas and developing appropriate mitigation strategies. LÄS MER

7. 20. Exploring the Importance of Women's Educational Attainment in HIV Risk Prediction : A Comparative Study of Logistic Regression, Random Forest and XGBoost

   Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Towe Wallkulle; [2023]
   Nyckelord :;

   Sammanfattning : Due to extensive HIV testing and treatment programs, the rate of new HIV infections has declined in recent years. However, young women South of the Sahara continue to be disproportionately burdened by the epidemic. The aim of this thesis is to explore the complex association between women's educational attainment and HIV prevalence. LÄS MER
