1. 16. Holistic embedding of equivalent conicity in wheelset maintenance

   Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

   Författare :Philipp Linzbichler; [2023]
   Nyckelord :Railway Operation; Equivalent Conicity; Wheelset Maintenance; Smart Maintenance; Data Analysis; Järnvägsdrift; Ekvivalent Konicitet; Hjulset Underhåll; Smart Underhåll; Dataanalys;

   Sammanfattning : With continuing digitization of railways an increasing number of data is recorded but particularly in operation advanced analysis tends to be partially rudimentary. Yet, it is essential to implement sophisticated processing for all records in order to develop more purposeful and predictive vehicle maintenance strategies that adhere to the increasing requirements imposed by the homologation.

3. 17. Human Rights Violations and Machine Learning - Cluster Analysis of Countries using the CIRIGHTS Dataset

   Magister-uppsats, Lunds universitet/Statistiska institutionen; Lunds universitet/Nationalekonomiska institutionen

   Författare :Emilie Ståhle; Emilie Haubrich; [2023]
   Nyckelord :Human Rights Violation; Clustering; K-Means; Latent Class Analysis; Transition Matrix; Business and Economics;

   Sammanfattning : This master's thesis explores the use of unsupervised machine learning techniques to cluster countries based on their degree of human rights violations. Accordingly, the study evaluates the performance of two clustering methods, K-Means clustering and Latent Class Analysis (LCA), using two cluster validation metrics (Silhouette Coefficient and Dunn Index), as well as an Accuracy measure using the Human Rights index.

4. 18. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

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

   Författare :Ellen Grace Soroka; [2023]
   Nyckelord :Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

   Sammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER

5. 19. Customer segmentation in Retail: An Experiment in Sweden

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Nagma Athar Memon; [2023]
   Nyckelord :Customer Segmentation; Customer Relationship Management; Clustering; RFM; LRFMP;

   Sammanfattning : The retail industry is continuously transforming due to digitalization, globalization, urbanization, and automatization. These factors contribute to new and more transparent retail with new customer behaviors, business models, and international competition. LÄS MER

7. 20. Ett paradigmskifte i synen på sociala problem och en ny era av straff - En tematisk analys av Tidöavtalet och dess innehåll

   Kandidat-uppsats, Lunds universitet/Socialhögskolan

   Författare :Rina Maloku; Rosemarie Pallin; [2023]
   Nyckelord :Tidöagreement; neoliberalism; right-wing populism; social problems; vulnerable groups; Social Sciences;

   Sammanfattning : The publication of the Tidöagreement composed by Sweden's government and the Swedish democrats has encouraged a deep-rooted concern in which ways Swedish society and vulnerable groups will be affected by the said document. Increased knowledge of the Tidöagreement and the way it is composed is vital for understanding the way in which social work will be affected and how vulnerable groups can be helped despite the agreement's suggestions.
