| dc.description.abstract | Centroidal Voronoi tessellation (CVT)는 연관된 generating point들이 대응하는 Voronoi region들의 무게중심이 되는 성질을 만족하는 주어진 집합의 Voronoi tessellation이다. 이 논문에서, CVT는 시간에 의존하는 버거스 방정식에 대한 reduced-order model을 유도하기 위해 이용된다. 그리고 나서, 그 결과들이 유한요소법 (finite element method)을 이용한 결과들 그리고 proper orthogonal decomposition (POD)를 이용한 결과들과 비교된다. | - |

| dc.description.alternativeAbstract | A centroidal Voronoi tessellation (CVT) is a Voronoi Tessellation of a given set such that the associated generating points are centroids (centers of mass) of the corresponding Voronoi regions. In this thesis, CVT is utilized to derive reduced-order models for the time-dependent Burgers equation. Then, CVT-based algorithms are compared with numerical results obtained from finite-element discretization and proper orthogonal decomposition (POD)-based algorithms. | - |
