Construction of an Input-Output Income Distribution Matrix for the U.S.
1999In this chapter, we explain the construction of a set of disaggregated personal income accounts to be incorporated into a 1987 Social Accounting Matrix (SAM) of the U.S. The accounts are disaggregated according to eleven income brackets and eighty economic sectors on the basis of the 2-digit U.S. Bureau of Economic Analysis classification.

Web service composition using input/output dependency matrix
Proceedings of the 3rd workshop on Agent-oriented software engineering challenges for ubiquitous and pervasive computing, 2009Composition of web services has received increased interest with emerging application development architecture-Service Oriented Architecture (SOA). Doing composition (semi-) automatically is a crucial aspect in overcoming runtime problems that arise due to dynamic nature of runtime environment.

Application of Green Input Output Matrix to Sustainable Development in China
PICMET '09 - 2009 Portland International Conference on Management of Engineering & Technology, 2009The 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 ...

Estimating the Noise Covariance Matrix for Input-Output Filters
IFAC Proceedings Volumes, 1981Abstract 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.

An investigation of methods to improve input/output waveforms in matrix converters
Electrical Engineering in Japan, 2005AbstractThe matrix converter is a three‐phase AC‐to‐AC direct converter without any energy storage requirement such as DC link capacitors. However, the matrix converter has some practical problems such as the necessity for bidirectional power devices, necessity for special commutation sequence, and complexity of the control method.

IEEE Transactions on Automatic Control, 1975
This short paper concerns the identification of a linear time-invariant discrete system represented by a matrix transfer function in the form of a matrix fraction. The relations between external and internal descriptions are discussed, and all matrix transfer functions satisfying given input-output observations are determined.

An exact method for triangularizing input-output matrixes
2007Let M be a non-negative square matrix. To each permutation P of its rows and columns we associate the sum S(P)of the cells that lie above the diagonal. By triangularization of the matrix M we mean the combinatorial problem of finding a permutation that minimizes S(P). The problem is NP hard, except that the case of an order matrix.

CELL‐CORRECTED RAS METHOD (CRAS) FOR UPDATING OR REGIONALIZING AN INPUT–OUTPUT MATRIX
Journal of Regional Science, 2009ABSTRACT The RAS method is used to update or regionalize a single matrix such that it conforms to new row and column totals. This paper presents a correction of the RAS method (CRAS) that uses cell variation distributions calculated from multiple matrices of different periods or different regions.

Scaling of input-output data and number of conditionality of a matrix of Grama
2012 IEEE 11th International Conference on Actual Problems of Electronics Instrument Engineering (APEIE), 2012Is considered procedure of scaling of the input and output data for increase of accuracy of estimations in problems of parametrical identification of the objects described by models in the form of space state. Offered procedure allows to eliminate influence of property of small changes of sequence of measurements concerning some constant.

A MULTI-OBJECTIVE ASSESSMENT OF INPUT–OUTPUT MATRIX UPDATING METHODS
Economic Systems Research, 2009This paper shows that important insights can be lost when assessing the relative performance of balancing methods solely based on individual optima. This is demonstrated through a multi-objective assessment. A trade-off curve between RAS and sign-preserving absolute differences (SPAD) is obtained based on the 60×60 Norwegian 2001 input–output table ...
