This paper analyzes the power consumption of an array pipelined multiplier. To precisely realize a low power pipelined multiplier, the analytical model for a clocking system is presented. Simulation results show that the storage element is the key-component in a high performance pipelined multiplier macro. Compared with the conventional DFF and latch, the new low power DFF as PTTFF [6] achieves...

Linear-constant velocity-pressure elements are enriched with residual-free macro bubbles. Static condensation prompts a stabilized method for this element, where mesh-dependent jumps of the normal stress are added across internal edges of the underlying macroelements. This procedure renders the SIMPLEST element stable.

Critical speed analysis of rotor systems is a difficult process due to the fact that there exists no direct formula to determine the natural frequency of a multi-section rotor. Finite Element packages provide a suitable platform for such an analysis but demand considerable experience on part of the user to perform modeling, meshing, solving and post-processing. The primary objective of this pap...

A finite element heterogeneous multiscale method is proposed for solving the Stokes problem in porous media. The method is based on the coupling of an effective Darcy equation on a macroscopic mesh, with unknown permeabilities recovered from micro finite element calculations for Stokes problems on sampling domains centered at quadrature points in each macro element. The numerical method account...

the continuum based approaches don’t provide the correct physics in atomic scales. on the other hand, the molecular based approaches are limited by the length and simulated process time. as an attractive alternative, this paper proposes the fixed interfacial multiscale method (fimm) for computationally and mathematically efficient modeling of solid structures. the approach is applicable to mult...

Nonnegative bivariate interpolants to scattered data are constructed using some C macro-element spline spaces. The methods are local, and rely on adjusting gradients at the data points to insure nonnegativity of the spline when the original data is nonnegative. More general range-restricted interpolation is also considered.

This paper reviews the quantitative methods developed at selected authorities for stress testing credit risk, focusing in particular on the methods used to link macroeconomic drivers of stress with bank-specific measures of credit risk (macro stress test). Authorities with a mandate for financial stability are particularly interested in quantifying the macro-to-micro linkages and have developed...

The increasing use of advanced sensing technologies for strain measurements necessitates the development of strain-based identification methodologies. In this study, a three-step neural network strategy, called direct soft parametric identification (DSPI), is presented to identify the member stiffness and damping parameters of a truss structure directly from free vibration-induced strains. The ...

A crystallographic homogenization procedure is introduced to the conventional static-explicit and dynamic-explicit finite element formulation to develop a multi scale – double scale – analysis code to predict the plastic strain induced texture evolution, yield loci and formability of sheet metal. The double-scale structure consists of a crystal aggregation – micro-structure and a macroscopic el...
