regional input-output tables historical background goes back to 1950 when its idea was proposed by walter isard. in iran, regional accounts generation started in the fifth development plan before the islamic revolution, but these accounts have been generated only for some provinces. the generation and completion of these accounts and tables on the basis of surveying and mechanical methods or a ...

We explain the raison d’être and basic ideas of input/output logic, sketching the central elements with pointers to other publications for detailed developments. The motivation comes from the logic of norms. Unconstrained input/output operations are straightforward to define, with relatively simple behaviour, but ignore the subtleties of contraryto-duty norms. To deal with these more sensitivel...

The memory plates can be used with con ventional 2-to-1 current -coincidence drive. This is particularly suitable for compact, lower power consuming, transistor driven, memories of relatively small capacity. A new method is proposed of driving memories particularly suitable for plates. The memory plates are driven by an end-on switch itself made of plates. The switch operates in a set-a-line an...

three artificial neural networks (ann) models; general regression neural network (grnn), redial basis function (rbf) and three layer multiple perceptron network were carried out to evaluate the prediction of the apparent metabolizable energy (ame) of wheat and corn from its chemical composition in broiler. input variables included: gross energy (ge), crude protein (cp), crude fiber (cf), ether ...
