1. 6. A Matrix-less Method for Approximating the Eigenvectors of Toeplitz-like Matrices

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : David Meadon; [2021]
   Keywords : ;

   Abstract : Matrix-less methods (MLM) have successfully been used to efficiently approximate the eigenvalues of certain classes of structured matrices. Specifically, the method has been used to approximate the eigenvalues of Toeplitz and Toeplitz-like matrices. READ MORE

3. 7. Minimal Deformation Methods for Loop Closure

   University essay from Lunds universitet/Matematik LTH

   Author : Erik Tegler; [2021]
   Keywords : Mathematics and Statistics;

   Abstract : This thesis proposes a method for how to find duplicated 3D points in a single Structure from Motion point cloud. Together with related articles, this forms a possible solution to the loop closure problem. The proposed method works by first selecting candidate pairs of 3D points by comparing BRIEF descriptors of all points. READ MORE

4. 8. Modelling stellar streams around the Milky Way

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Hyerin Jang; [2021]
   Keywords : Physics and Astronomy;

   Abstract : Stellar streams around the Milky Way (MW) have been observed by wide sky surveys, and studied to understand the mass distribution of the MW. This is because streams are formed by a disruption of a globular cluster or a dwarf galaxy under the influence of the gravitational field of the MW. READ MORE

   Abstract : In this thesis I hope to provide a clear and concise introduction to Feigenbaum scaling accessible to undergraduate students. This is accompanied by a description of how to obtain numerical results by various means. READ MORE

6. 10. Limiting Behavior of the Largest Eigenvalues of Random Toeplitz Matrices

   University essay from KTH/Matematik (Inst.)

   Author : Samuel Modée; [2019]
   Keywords : Random matrix; Toeplitz matrix; largest eigenvalues; eigenvectors; slumpmatriser; Toeplitz matrices; största egenvärde; egenvektorer;

   Abstract : We consider random symmetric Toeplitz matrices of size n. Assuming that the entries on the diagonals are independent centered random variables with finite γ-th moment (γ>2), a law of large numbers is established for the largest eigenvalue. READ MORE
