This paper deals with a computational analysis of the influence of the pressing method and part geometry on the final density
distribution in the cold compaction process of ceramic alumina powders. The analysis is based on the explicit finite-element
model proposed and validated in a previous study. The mechanical behavior of the processing material is described using a
multisurface elastoplastic model, the modified Drucker-Prager/Cap model

We establish a natural correspondence between the finite order automorphisms of the function singularities X
9 and the complex crystallographic groups. A complete list of the related objects is obtained.

At the end of the twentieth century, in mathematical physics, the Knizhnik-Zamolodchikov equations for the root systems A
n
and their generalizations for the root systems of types B
n
, C
n
, and D were constructed. For the root system of type G
2, the vector version of the Knizhnik-Zamolodchikov equations was obtained by M. P. Zamakhovskii and V. P. Leksin. However,
the tensor version of these equations has remained unstudied. In this paper, the Knizhnik-Zamolodchikov equations associated
with the root system of type G
2 are considered.

Nowadays, there is high demand for sensitive gas sensors both for human and environmental monitoring. This paper deals with a high-resolution (0.2 ppb) laser-based photoacoustic spectroscopic system realized at ENEA Frascati, Italy, applied for monitoring stress in scuba divers during sustained immersion by analyzing breath samples. Blood tests and psychometric tests for scuba divers were performed at Catholic University in Rome. Results will be reported and discussed. 相似文献
