Landslides are frequent and catastrophic geological hazards, forecasting their movement is an important aspect of risk assessment engineering prevention. Based on the integrated deep displacement three-dimensional measuring sensor with sensing unit array structure, improved multivariable grey model based dynamic background value feedback proposed to build predictive models for evolutionary cond...

In this paper we propose a practical approach for on-chip inductance extraction. This approach differs from previous methods in that it uses circuit characteristics to obtain a sparse, stable and symmetric inductance matrix, using the concept of resistance dominant and inductance dominant lines. Experimental results show that only the important inductance terms related to strong inductance coup...

Abstract: For high-speed circuits, on-chip inductance can no longer be ignored. This paper deals with inductance in the presence of multi-layered meshes used for on-chip power supplies. We have shown ways of designing power/ground (p/g) mesh that reduce inductance. Accurate 3-dimensional inductance extraction problem is intractable for large chips. We have demonstrated the feasibility of using ...

Based on product related scenarios, the impact of on-chip inductance on power supply integrity is analyzed. The impact of varying current profiles is shown to be minimal. In a regular power grid with regular bump connections, the impact of on-chip inductance on the cycle average of the supply voltage can be neglected, even for a worst case estimation of on-chip inductance. Whereas, the maximum ...

We have studied the kinetic inductance fraction (ratio of kinetic inductance to total inductance) of superconducting coplanar waveguides (CPWs) by measuring the resonance frequency of CPW transmission line resonators. We describe a procedure for accurately determining the kinetic inductance of transmission line geometries with small kinetic inductance fractions. In this approach, we compare the...

There has recently been much effort behind the development of NDE methods applicable to the detection of surface/subsurface flaws in thin metallic structures with a rapid scan capability. One such method, an electromagnetic technique using a current-sheet parallel to the surface of a specimen in order to induce eddy current flow shows a high potential for satisfying the rapid scan requirement s...
