On-Line Control of Stresses in the Power Unit Pressure Elements Taking Account of Variable Heat Transfer Conditions

open access: yesEnergies, 2021
Coal-fired power units, now balancing power shortages in the power system, must be characterised by increasingly higher flexibility of operation. This means faster start-ups and the capacity for frequent decreases and increases in the power output. These

Positive elements and theB * condition

open access: yesMathematische Zeitschrift, 1986
The basic theory of the ''positive elements'' of a \(B^*\)-algebra is derived from the \(B^*\) condition by a combination of totally elementary argument, the spectral radius formula and the square root lemma. In the process a sort of ''topological norm additivity'' emerges for positive elements.
