starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

• The gas turbine model is validated by a well-used commercial software. An adapted sequential method established for fault diagnosis of aero engines. Effect heat soakage considered in under dynamic conditions. economic impact our assessed hydrogen powered flights. could diagnose faults successfully states. At present, engine mainly based on the steady-state condition at cruise phase, and path ...

Harmonics have become an important issue in modern power systems. The widespread penetration of non-linear loads to emerging power systems has turned power quality analysis into an important operation issue under both steady state and transient conditions. This paper employs an Extended Harmonic Domain (EHD) based framework for dynamic analysis of long term analysis over voltages during the tra...
