This paper discusses a method of stabilizing Lagrange multiplier fields used to couple thin immersed shell structures and surrounding fluids. The method retains essential conservation properties by stabilizing only the portion of the constraint orthogonal to a coarse multiplier space. This stabilization can easily be applied within iterative methods or semi-implicit time integrators that avoid ...

This paper proposes a reconfigurable finite impulse response (FIR) filter using constant multiplier algorithm with applying pipeline technique. To design a high performance Reconfigurable fir filter, according to the proposed constant multiplier algorithm with Retiming pipelining method has been applied in co-efficient generator block. This method capable of reducing the switching activity of c...

In this paper, an analysis of 3-dimensional problem using a fictitious domain method based on distributed Lagrange multiplier is discussed. Using this approach allows us to compute moving boundary problems successfully. First of all, how to use a fictitious domain method using navier stokes equations is explained. Next, incompressible viscous fluid around circular cylinder and ball are restrict...

Booth encoded Multiplier is used to reduce the hardware utilization in chip level designing in VLSI projects. The present project is focusing on designing and developing a powerful Booth encoded multiplier integrated with Carry Select Adder [CSLA]. Primarily the on hand Booth encoding multiplier is used in multiplication operations based on signed numbers only. The multipliers such as braun arr...

This work presents the coupling of two locally conservative methods for elliptic problems: namely, the discontinuous Galerkin method and the mixed finite element method. The couplings can be defined with or without interface Lagrange multipliers. The formulations are shown to be equivalent. Optimal error estimates are given; penalty terms may or may not be included. In addition, the analysis fo...

This paper proposes a new design and implementation method for a class of multiplier-less 2-channel 1D and 2D non-separable perfect reconstruction (PR) filter banks (FB). It is based on the structure proposed by Phoong et al. and the use of multiplier block (MB). The latter technique allows one to hrther reduce the number of adders in implementing these multiplier-less FB by almost 50%, compare...

The Lagrange multiplier method for combining observations and models (i.e., the adjoint method or “4DVAR”) has been avoided or approximated when the numerical model is highly nonlinear or chaotic. This approach has been adopted primarily due to difficulties in the initialization of low-dimensional chaotic models, where the search for optimal initial conditions by gradient-descent algorithms is ...

Comparing the performance of a set of activities or organizations under uncertainty environment has been performed by means of Fuzzy Data Envelopment Analysis (FDEA) since the traditional DEA models require accurate and precise performance data. As regards a method for dealing with uncertainty environment, many researchers have introduced DEA models in fuzzy environment. Some of these models ar...
