Stochastic collocation method for interconnect delay estimation in the presence of process variations

However as device feature size shrinks to below 65nm, the application of complex technologies and new materials will inevitably introduce stochastic process variations.

Theoretical solution for consolidation of composite foundations considering construction disturbance and loading effect;

In this paper,on the basis of the previous researches,the concept of construction disturbance is discussed,and an expression of disturbance degree is set up and the calculation model against heave for the stability of deep excavation is established.

An attempt is made to express the degree of construction disturbance by the shear strain on the basis of the study of compression characteristics of soils influenced by different shear strains.

In order to solve the environmental geotechnical damage, the strength, deformation, bearing capacity and collapsing deformation which are affected by moisture content and porosity ratio of soil under disturbance due to construction, are researched by means of loading and unloading tests.

Under the condition of artificial disturbances, the investigations were performed on a three dimensional boundary layer of a 45 degree swept back flat plate, which is subject to cross flow instability.

The degeneration trend of artificial disturbance in turbulent boundary layer is obtained for different disturbing frequencies.
