1. 1. Simulating Mobility of Large Population using Mobile Application Data

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Mattias Rydström; Diana Salim; [2024-01-23]
   Nyckelord :Human mobility; mobile application data; synthesize activity plans;

   Sammanfattning : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.

3. 2. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Rasmus Staaf; [2024]
   Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

   Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

4. 3. Beyond the Bonus Check: A qualitative study unraveling the complexities of employee motivation in a PFP environment

   C-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

   Författare :Olivia Thomsson; Tindra Sturk; [2024]
   Nyckelord :Performance management; Pay-for-Performance; Bonus systems; Motivation; Expectancy Theory;

   Sammanfattning : This thesis is a qualitative single-case study of employee motivation in a PFP environment within a Swedish business unit of one of the world's largest project development- and construction companies. The aim is to investigate how employees perceive and experience the impact of a PFP bonus system on their motivation. LÄS MER

5. 4. 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.

7. 5. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

   Master-uppsats, KTH/Materialvetenskap

   Författare :Josefin Mvele Svensson; [2024]
   Nyckelord :Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

   Sammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.
