Identifier: http://hdl.handle.net/1959.14/200665
Description: The problem discussed in this paper is that of estimating the period of a sequence of periodic events when the measurements of the occurrence times are noisy and sparse. The problem is common to many ... More

Identifier: http://hdl.handle.net/1959.14/23833
Description: We introduce and evaluate a block-iterative Fisher scoring (BFS) algorithm for emission tomography. Regularization is achieved by penalized likelihood with a general quadratic penalty. When the algori ... More
