1. 31. Machine Learning of Crystal Formation Energies with Novel Structural Descriptors

   University essay from Linköpings universitet/Teoretisk Fysik

   Author : Claudia Bratu; [2017]
   Keywords : Machine learning; crystal; formation energy; kernel ridge regression; KRR; representation; descriptor; feature vector representation;

   Abstract : To assist technology advancements, it is important to continue the search for new materials. The stability of a crystal structures is closely connected to its formation energy. By calculating the formation energies of theoretical crystal structures it is possible to find new stable materials. READ MORE

4. 33. Probabilistic Approach to InsulationCoordination

   University essay from Uppsala universitet/Elektricitetslära

   Author : Alexander Bilock; [2016]
   Keywords : VSC-HVDC; KDE; Insulation coordination;

   Abstract : The present work was performed at HVDC ABB as an initial study on how to adopt probabilistic concepts into the VCSHVDC insulation coordination.

5. 34. Road and landscape features affecting the aggregation of ungulate vehicle collisions in southern Sweden

   University essay from SLU/Dept. of Ecology

   Author : Magnus Sjölund; [2016]
   Keywords : cluster; kernel density estimation; spatial pattern; traffic safety; ungulate; vehicle accidents; wildlife;

   Abstract : Ungulate-vehicle collisions (UVC) are increasing in Sweden and raises concern to traffic safety, socio-economics and wildlife management. Accident numbers are steadily growing but the trends are not well related to the changes in ungulate population sizes or hunting bag statistics. READ MORE

6. 35. Multiclass Density Estimation Analysis in N-Dimensional Space featuring Delaunay Tessellation Field Estimation

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Yuhao Li; [2016]
   Keywords : ;

   Abstract : Multiclass density estimation is a method that can both estimate the density of a field and classify a given point to its targeted class. Delaunay Tessellation Field Estimation is a tessellation based multiclass density estimation technique that has recently been resurfaced and has been applied in the field of astronomy and computer science.
