Wolfgang Hackbusch - Max Planck Institute for Mathematics in the Sciences
The technique of hierarchical matrices tries to approximate fully populated large-scale matrices in a representation only requiring a storage of O(n log(n)). Of similar importance is the fact the all...

Wolfgang Hackbusch - Max Planck Institute for Mathematics in the Sciences
An example of a tensor is a grid function in a d-dimensional cube with n grid points per direction. Its dimension is n^d. In cases of n=d=1000 it seems hopeless to apply numerical methods....

Yasmeen Shameen - Indian institute of Science Education and Research, Pune, INDIA
Covering arrays are a relaxation of orthogonal arrays to covering hypothesis that have been successfully applied in the design of test suites for testing systems such as software, circuits and...

Raymond H. Chan - The Chinese University of Hong Kong
  Ground-based astronomy refers to acquiring images of objects in outer space via ground-based telescopes. Because of atmospheric turbulence, images so acquired are blurry. One way to estimate the...
