Fast reproduction of time-dependent diffusion calculations using the reduced order model based on the proper orthogonal and singular value decompositions

Autor: Tomohiro Endo, Akio Yamamoto, Kosuke Tsujita

Publikováno v: Journal of Nuclear Science and Technology. 58:173-183

An efficient reduced order model (ROM) for time-dependent diffusion calculations using the proper orthogonal decomposition (POD) is proposed. Employing the singular value decomposition (SVD) and lo...

Efficient reduced order model based on the proper orthogonal decomposition for time-dependent MOC calculations

Autor: Kosuke Tsujita, Tomohiro Endo, Akio Yamamoto

An efficient reduced order model (ROM) for time-dependent transport calculations using the method of characteristics (MOC) is proposed. In the present ROM, the flux distributions and the net neutron currents between the adjacent unstructured mesh reg

Right ventricular basal inflow and outflow tract diameters overestimate right ventricular size in subjects with sigmoid-shaped interventricular septum: a study using three-dimensional echocardiography

Autor: Sanae Kaga, Kazunori Okada, Yoichi Sakamoto, Taisei Mikami, Nobuo Masauzi, Kosuke Tsujita

Publikováno v: The International Journal of Cardiovascular Imaging. 35:1211-1219

Sigmoid-shaped ventricular septum (SS), a frequently encountered minor abnormality in echocardiographic examinations of the elderly, may have some influence on RV shape. We aimed to determine the influence of SS on the accuracy of the 6 RV linear dia
