The Transfer Matrix as Operator or Input/Output Map

2020
In the standard discrete-time and continuous-time cases and for relevant classes of signals, we interpret the transfer matrix of an input/output behavior as transfer operator which maps input signals to output signals. In the most important settings, this action is given by convolution. The transfer operator generalizes the gain matrix. We characterize

Input-output equivalent representation of non-regular polynomial matrix descriptions

Proceedings of the 1997 American Control Conference (Cat. No.97CH36041), 1997
A simple method is proposed for representing a polynomial matrix description in a descriptor system form. The realisation preserves the input-output properties of the original polynomial matrix representation. The discussion is based on a generalised concept of the transfer function for dynamic systems which are in polynomial form and not necessarily ...

The input-output matrix

1976
The simplest way to describe the economic structure of a region is by input-output analysis: that has been done for the two regions in our model.

The pollution input-output matrix

1976
Before dealing with the problem of pollution dispersion and its interregional effects, we must first discover the pollution quantities emitted by regions, and then determine the dispersion of pollution.

Direction Preserving Wiener Matrix Filtering for Ambisonic Input-output Systems

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
We present a spatial matrix filtering framework for noise reduction in the spherical harmonics (ambisonics) domain (SHD), which outputs an SHD signal vector rather than one signal as commonly provided by beamforming approaches. We discuss two spatial matrix filtering methods: A multi-beamformer method using known propagation vectors of the desired ...

Input/output characteristics of a matrix ion‐chamber electronic portal imaging device

Medical Physics, 1994
The input/output characteristics of a matrix liquid ion‐chamber electronic portal imaging device (EPID) are investigated to elucidate the imaging properties of EPIDs. The radiation input to the detector, represented by dose rate, and the pixel value output from the device are related by a characteristic curve. Various incident radiation intensities are

Production and Income: Input-Output and Social Accounting Matrix Approaches

Rivista Internazionale di Scienze Sociali
The System of National Accounts (SNA) and the evolution of satellite accounts allowed the development of increasingly realistic and disaggregated macroeconomic models for policy design. The Social Accounting Matrix (SAM), the sophisticated tool within SNA, provides the integration of non-economic and territorial elements into the circular flow of ...

Estimating the Noise Covariance Matrix for Input-Output Filters

IFAC Proceedings Volumes, 1981
Abstract An algorithm is introduced to estimate the zero-shift covariance of additive input and output noise in a situation when the process inputs and outputs are measured and the input-output model of the process is known. It is assumed tat the noise to be estimated is uncorrelated in time.

Application of sparse matrix techniques to inter-regional input-output analysis

Economics of Planning, 1979
Combining the concepts described in this paper makes it possible to solve inter-regional input-output systems (and other types of large, sparse, linear systems) with considerable efficiency in storage and computation. The exact number of operations and corresponding savings in computational time and storage depend on the particular zero-non zero ...

Application of green input output matrix to sustainable development in China

PICMET '09 - 2009 Portland International Conference on Management of Engineering & Technology, 2009
The green input output matrix will not only include the economic factors as the traditional input output matrix, but also include the environmental factors such nature resources, environmental pollution and environmental protection. Therefore the input output matrix with environmental pollution and wastage recycling is set up based on data from China ...
