CoSaMP: Iterative signal recovery from incomplete and inaccurate samples
Compressive sampling offers a new paradigm for acquiring signals that are compressible with respect to an orthonormal basis. The major algorithmic challenge in compressive sampling...

Iteratively constructing preconditioners via the conjugate gradient method
We consider the problem of solving a symmetric, positive definite system of linear equations. The most well-known and widely-used method for solving such systems is the preconditi...

A model reference approach to safe controller changes in iterative identification and control
A controller change from a current controller which stabilises the plant to a new controller, designed on the basis of an approximate model of the plant and with guaranteed bounds...

A New Synchronous Lower Bound for Set Agreement
Abstract. We have a new proof of the lower bound that k-set agreement requires f/k + 1 rounds in a synchronous, message-passing model with f crash failures. The proof involves cons...
