TL;DR: In this paper, the effects of small amounts of Ta2O5 and MgO additives on sintering, microstructure and mechanical properties of ultra-pure alumina ceramics have been studied by metallography, SEM and TEM.

TL;DR: In this article, crystal microstructures, pure and doped with K 2 O or Na 2 O β-C 2 S, were studied by HREM and it was shown that the twin was not observed in pure β-c 2 S. After doping, many (100) twins were produced and evidence of the existence of (001) twins was observed.

TL;DR: In this article, the fractal dimension of the irregular cluster, D, is calculated in terms of the density scaling function, approaching fractal dimensions of the Percolation backbone, DBB.
Abstract: The microstructure of phase-separated glass is described by fractal geometry. The fractal character of the irregular cluster in the resultant morphology of typical phase-separated glass by spinodal decomposition exists only over a limited length scale, and the fractal dimension of the irregular cluster, D, is calculated in terms of the density scaling function, approaching the fractal dimensions of the Percolation backbone, DBB.

TL;DR: This paper considers the serial queueing system with two service mechanisms but there is only a single server in each mechanism, i.e. the first counter is loseing system, the second is finite waiting system.
