Analysis and treatment of vibration of 1000MW secondary reheat steam turbine with super-long single-support shafting [PDF]
In the context of new energy grid connection, thermal power units are gradually developing in the direction of large-scale and long-axis. However, due to the static deflection of the long shaft system, the rotor presents the shape of a lift curve during ...

Generating generic functions [PDF]
We present an approach to the generation of generic functions from user-provided specifications. The specifications consist of the type of a generic function, examples of instances that it should "match" when specialized, and properties that the generic function should satisfy.

Generalized Symmetries for Generalized Gravitons
Construimos simetrías generalizadas para la gravedad de Einstein linealizada en dimensiones arbitrarias. Las consideraciones de primer principio en la teoría cuántica de campos obligan a que las simetrías generalizadas aparezcan en pares duales. Verificar esta predicción nos ayuda a encontrar el conjunto completo de cargas conservadas no triviales ...
