1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Robin Drevet; [2024]
   Keywords : space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

   Abstract : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

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

   University essay from Lunds universitet/Matematisk statistik

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

   Abstract : 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.

4. 3. RENOVATION USING PREFABRICATED FAÇADE ELEMENTS

   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Aleksandra Milkova; Mohamed Soliman; [2024]
   Keywords : Keywords: Energy use; Reduce energy; EU; IVL; LKF; TES façade; Multi-active façade; Alingsås façade; Million Programme; Moisture risk analysis; Attachment; Thermal performance; WUFI; AUTOCAD; HEAT2; Technology and Engineering;

   Abstract : The building sector uses about 40% of the total global energy use. Sweden aims to reach its new goal to reduce the energy use in their residential sector as well as commercial sector by 20%, which should be reached by year 2020 and 50% by year 2050. READ MORE

5. 4. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution

   University essay from Lunds universitet/Statistiska institutionen

   Author : Marcus Stolz; Jonathan Christopher; [2024]
   Keywords : Monte Carlo integration; Quasi monte carlo integration; Random number generation; Mathematics and Statistics;

   Abstract : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). READ MORE

6. 5. Real-Time System Benchmarking with Embedded Linux and RT Linux on a Multi-Core Hardware Platform

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Kian Hosseini; [2024]
   Keywords : Real-time; Embedded systems; Benchmarking; Multicore;

   Abstract : To catch up with the growing trend of parallelism, this thesis work focuses on the adaption of embedded real-time systems to a multicore platform. We use the embedded system of Xilinx ZCU-102, a multicore board, as an example of an embedded system without getting deep into its architecture. READ MORE
