1. 1. A spatially explicit model of segregation dynamics : Comparing the Schelling and the Sakoda model

   Master-uppsats, Linköpings universitet/Institutet för analytisk sociologi, IAS

   Författare :Philip Öberg; [2023]
   Nyckelord :residential segregation; agent-based modeling ABM ; social simulation; multi-dimensional measurement; multi-scale measurement;

   Sammanfattning : The scientific consensus has for long been that residential segregation is best conceived of as a multidimensional phenomenon that can exist on several geographical scales (Massey & Denton, 1988; Lee et al., 2008; Reardon & O’Sullivan, 2004; Reardon et al., 2008). LÄS MER

3. 2. Multitask Convolutional Neural Network Emulators for Global Crop Models - Supervised Deep Learning in Large Hypercubes of Non-IID Data

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Amanda Nilsson; [2020]
   Nyckelord :Multitask Learning; Convolutional Neural Network CNN ; Branched Neural Network; Dynamic Global Vegetation Models DGVM ; Automated Feature Extraction; Feature Importance; Supervised Machine Learning; Emulator; Surrogate Model; Response Surface Model; Approximation Model; Metamodeling; Model Composition; Regularization; Robustness; Hyperparameter Optimization; Mathematics and Statistics;

   Sammanfattning : The aim of this thesis is to establish whether a neural network (NN) can be used for emulation of simulated global crop production - retrieved from the computationally demanding dynamic global vegetation model (DGVM) Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS). It has been devoted to elaboration with various types of neural network architectures: Branched NNs capable of processing inputs of mixed data types; Convolutional Neural Network (CNN) architectures able to perform automated temporal feature extraction of the given weather time series; simpler fully connected (FC) structures as well as Multitask NNs.

4. 3. Social capital, environmental policy attitudes and the mediating role of climate change beliefs

   M1-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Robin Saberi Nasseri; [2019]
   Nyckelord :social trust; generalized trust; social networks; civic participation; latent variable modeling; structural equation modeling;

   Sammanfattning : In order to combat the potential threats of climate change, effective policy setting and implementation is crucial. A variable which has been shown to have significant explanatory power on the success of different public policy areas is social capital; a multidimensional concept encompassing social relationships and norms ability to mobilize and facilitate common goals.

5. 4. Effektivisering av förvaltningsskedet med hjälp av flerdimensionella BIM-modeller : En studie om BIM 360 Ops

   Kandidat-uppsats, KTH/Byggteknik och design

   Författare :Mona Issa; Rawand Nabaz Taha; [2019]
   Nyckelord :BIM; Property management; Autodesk; Revit; Construction process; Digitalization.; BIM; Fastighetsförvaltning; Autodesk; Revit; Byggprocessen; Digitalisering.;

   Sammanfattning : Den tekniska utvecklingen går fort fram. Tillämpandet av BIM (Byggnadsinformationsmodellering) blir allt vanligare inom byggsektorn. Dock halkar förvaltningen efter i utvecklingen, i jämförelse med byggprocessens tidiga skeden, projektering- och produktionsskedet. LÄS MER

7. 5. Experiences in Swedish Healthcare : Modeling Patient Satisfaction with SEM for Patients with Good and Poor Health

   Magister-uppsats, Uppsala universitet/Statistiska institutionen

   Författare :Agnes Lindvall; [2019]
   Nyckelord :;

   Sammanfattning : Patient satisfaction is important for patients, and is an important aspect of a healthcare system. Patient satisfaction is a multidimensional concept consisting of patient experiences in different areas during the healthcare visit. LÄS MER
