To ensure reliable and efficient operation of gas turbines, multiple model (MM) approaches have been extensively studied for online fault detection and isolation (FDI).However, current MM-FDI approaches are difficult to directly apply to gas path FDI, which is one of the common faults in gas turbines and is understood to mainly be due to the high c
Alumina-based foam ceramic caruso milk thistle filters were fabricated by using alumina, SiC, magnesia powder as major materials.It has been found that this ceramic filter has a uniform macrostructure for filtering molten metals.The influences of SiC and magnesia content, the sintering temperatures on ceramic properties were discussed.Aluminabased
Nowadays the automotive industry mostly prefers innovative solid-state welding technologies that would enable to welding of lightweight and high-performance materials.In this work, 3105-H18 Aluminium alloy (Al) and pure Copper (Cu) specimens with 0.5 mm thickness have been ultrasonically welded in a dissimilar (Al-Cu) manner.Optimization of process
The article presents a systemic and historical view of wars taking into account the generalization of modern concepts about their nature and causes.The generalization is produced on the basis of a political and sociological apparatus with such basic concepts as: "concerns" of different types (including "interests", "motives", "goals", "values"), an
