We propose an automated way of determining the optimal number of low-rank components in dimension reduction of image data. The method is based on the combination of two-dimensional principal component analysis and an augmentation estimator proposed recently in the literature. Intuitively, the main idea is to combine a scree plot with information extracted from the eigenvectors of a variation matrix. Simulation studies show that the method provides accurate estimates and a demonstration with a finger data set showcases its performance in practice.

Studies of two-dimensional and three-dimensional phononic crystal structures
Tian, Yolan (University of Jyväskylä, 2016)This thesis focuses on studying phononic crystal structures. More specifically, it is aimed at fabrication and measurement of thermal properties of two-dimensional (2D) periodic microstructures and three-dimensional (3D) ... -

Growth of two-dimensional Au patches in graphene pores : a density-functional study
Antikainen, Saku (2016)Grafeenin löytämisen myötä kaksiulotteisten (2D) materiaalien tutkimus on edennyt huomattavasti viimeisen vuosikymmenen aikana. Myös 2D-metalleja on tutkittu, ja esimerkiksi atominpaksuinen rautakerros on onnistuttu ... -
Large two-dimensional electronic systems: Self-consistent energies and densities at low cost
Räsänen, Esa; Pittalis, Stefano; Bekcioglu, Gül; Makkonen, Ilja (American Physical Society, 2013)We derive a self-consistent local variant of the Thomas-Fermi approximation for (quasi-) two-dimensional (2D) systems by localizing the Hartree term. The scheme results in an explicit orbital-free representation of the ...
