This document describes in detail how reformulation to a Social Accounting Matrix (SAM) can be made in order to analyze the multiplier effects of a new sector. A different input composition, or technology, of the sector makes a conventional analysis of final-demand injections on existing sectors invalid. We show that the reformulation—so-called hypothetical integration—is an efficient way to in...

in this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (p&o;) mppt algorithm” is developed and investigated to control a hybrid electric energy source (heps). this ehps is composed of a fuel cell system (fc) and a solar panel (sp), as the main source and a supercapacitor bank (sc), as the auxiliary sour...

abstract. in this paper we study some relations between the power andquotient power graph of a finite group. these interesting relations motivateus to find some graph theoretical properties of the quotient power graphand the proper quotient power graph of a finite group g. in addition, weclassify those groups whose quotient (proper quotient) power graphs areisomorphic to trees or paths.

let a be a unital algebra over a field of characteristic zero. we show that every derivation from( ) n m a into its dual ( ) n m a ∗ is the sum of an inner derivation and a derivation induced by a derivationfrom a into a∗

In this paper we present algebraic constructions of 3×3, 4× 4 and 6 × 6 Space-Time Codes, achieving full rate and full diversity. These codes have non-vanishing (in fact fixed) minimum determinants when the rate goes to infinity. Their construction is based on cyclic algebras with center equal to an algebraic field based on cyclotomic fields .

A nuclear continuous bagasse weigher was installed at Felixton Sugar Mill towards the end of the 1973174 crushing season and accuracy checks were performed on the weigher using an assized weighbridge as the reference standard. The average error was found to be 0,2% of full scale whilst the individual test errors were all well within 2% of full scale.
