Electron beam induced deposition of rhodium nanostructures

Fabio Cicoira

Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...

A fast algorithm for subspace state-space system identification via exploitation of the displacement structure

Daniel Kressner

Two recent approaches (Van Overschee, De Moor, N4SID, Automatica 30 (1) (1994) 75; Verhaegen, Int. J. Control 58(3) (1993) 555) in subspace identification problems require the computation of the R factor of the QR factorization of a block-Hankel matrix H, ...

A survey of spectral factorization methods

Ali H. Sayed

Spectral factorization is a crucial step in the solution of linear quadratic estimation and control problems. It is no wonder that a variety of methods has been developed over the years for the computation of canonical spectral factors. This paper provides ...

Displacement Structure and H ∞ Problems

Ali H. Sayed

The solution of H∞ problems requires the determination of contractive operators that map certain input signals to certain output signals. Such operators, and tests for their contractiveness, arise naturally in a scattering formulation of the generalized Sc ...

Combining Linear Dichomotizers to Construct Nonlinear Polychotomizers

A polychotomizer which assigns the input to one of

K, K \ge 3

, is constructed using a set of dichotomizers which assign the input to one of two classes. We propose techniques to construct a set of linear dichotomizers whose combined decision forms a nonl ...

A Stable and Efficient Algorithm for the Indefinite Linear Least-Squares Problem

Ali H. Sayed

We develop an algorithm for the solution of indefinite least-squares problems. Such problems arise in robust estimation, filtering, and control, and numerically stable solutions have been lacking. The algorithm developed herein involves the QR factorizatio ...

Improved Pairwise Coupling Classification With Correcting Classifiers

The benefits obtained from the decomposition of a classification task involving several classes, into a set of smaller classification problems involving two classes only, usually called dichotomies, have been exposed in various occasions. Among the multipl ...

Performance of CAP-specified linear algebra algorithms

Roger Hersch, Marc Mazzariol

The traditional approach to the parallelization of linear algebra algorithms such as matrix multiplication and LU factorization calls for static allocation of matrix blocks to processing elements (PEs). Such algorithms suffer from two drawbacks: they are v ...

Stabilizing the Generalized Schur Algorithm

Ali H. Sayed

This paper provides a detailed analysis that shows how to stabilize the generalized Schur algorithm, which is a fast procedure for the Cholesky factorization of positive-definite structured matrices R that satisfy displacement equations of the form $R - FR ...
