1. 1. Predicting True Sepsis and Culture-positive Sepsis in Intensive Care Unit with Machine Learning Techniques

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Zeyuan Wu; [2024]
   Nyckelord :Machine Learning; Diagnosis of Sepsis; XGBoost; Logistic Regression; Mathematics and Statistics;

   Sammanfattning : Sepsis, a serious medical condition often leading to patients requiring intensive care, has prompted numerous scientists to employ mathematical techniques to aid in its diagnosis. This thesis uses logistic regression and a machine learning technique, XGBoost, to predict true sepsis (as opposed to sepsis mimics) and culture-positive sepsis (among true sepsis) in critical care using blood test results, physiological measurements and other patient characteristics.

3. 2. Marktäckets och markfuktighetens påverkan på blomsterlupinens (Lupinus polyphyllus) utbredning i Jämtland

   Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Julia Svedh; [2024]
   Nyckelord :Garden lupine; Lupinus polyphyllus; soil moisture; land cover; invasive alien species; Jämtland; ; Blomsterlupin; Lupinus polyphyllus; marktäcke; markfuktighet; invasiva främmande arter; Jämtland;

   Sammanfattning : Biodiversity is the prerequisite for well-functioning ecosystem services that are crucial, like clean water and clean air. Invasive alien species (IAS) are a serious and long-term issue that is actively threatening the genetic diversity within ecosystems. LÄS MER

4. 3. Initial Development and Validation of Language-Based Assessments for Meaningful Change

   Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

   Författare :Ulrika Söderström; [2024]
   Nyckelord :meaningful change; depression; Large Language Models; AI; Social Sciences;

   Sammanfattning : Meaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. LÄS MER

5. 4. Optimization of a Floor Grinding Machine for Uniform Grinding Pattern

   Master-uppsats, Linköpings universitet/Produktrealisering

   Författare :Adithya Srikantha Dath; [2023]
   Nyckelord :Numerical Optimization; Floor Grinders; Grinding Pattern; Engineering Optimization; Model Based Systems; Data Analysis;

   Sammanfattning : Husqvarna Construction is one of the leading construction machinery manufacturers in the world. To stay in the forefront, investing in novel methods to model, test & and optimize machinery is crucial. The most important part of development and testing is to bridge the gap between desired and actual results. LÄS MER

7. 5. The OpenXO. 3D Printed Modular Exoskeleton Segment

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Árni Þór Þorgerirsson; [2023]
   Nyckelord :Exoskeleton; Open-Source; Fused Filament Fabrication FFF ; Cycloidal Drive; OpenXO; precision fabrication;

   Sammanfattning : Exoskeletons are wearable devices that enhance or supplement the user’s natural abilities. They have been demonstrated to be efective in alleviating pain, reducing work related injuries, improving working conditions, and can play a pivotal role in improving recovery times and recovery outcomes.
