The Lagrange multiplier based rate−distortion optimization has been proved an effective technique in hybrid video codec design. To improve the coding efficiency, an efficient Lagrange multiplier selection method is presented in this paper. As an extension to our previous work, the Laplace distribution based rate model is further refined by taking correlations among successive frames into accoun...

It is demonstrated that the pre-dual for problems with total bounded variation regularization terms can be expressed as bilaterally constrained optimization problem. Existence of a Lagrange multiplier and an optimality system are established. This allows to utilize efficient optimization methods developed for problems with box constraints in the context of bounded variation formulations. Here, ...

The relationship between Coale's method and Reverse Survival method has been investigated in this article. Since Coale's method produces estimates which are found to be approximately equal to that of reverse survival method, it is useful to determine a constant multiplier to make Coale's estimates equal to that of the reverse survival method. In this effort, the west model life tables have been...

— A finite element method requiring only C° éléments is developed for the approximation ofthefirst boundary value problem for the polyharmonic équation, based on the reformulation of this problem as a system of second order équations. The resulting linear System of équations can be easily preconditioned and efficiently solved by the conjugate-gradient method.

In this paper we proposed a three stage pipelined finite-impulse response (FIR) filter, this FIR filter contains multipliers such as Hybrid multiplier, Booth multiplier algorithm and Array multiplier. In general, multiplication process consists of two parts as multiplicand and multiplier. According to the array multiplier, the numbers of partial products (PP) are equal to the number of bits in ...

In this paper we determine the structure of (c,1,...,1) polynilpotent multiplier of certain class of groups. The method is based on the characterizing an explicit structure for the Baer invariant of a free nilpotent group with respect to the variety of polynilpotent groups of class row (c,1,...,1).

Multipliers of reproducing kernel Hilbert spaces can be characterized in terms positivity $n \times n$ matrices analogous to the classical Pick matrix. We study for which it suffices consider bounded size $n$. connect this problem notion subhomogeneity non-selfadjoint operator algebras. Our main results show that multiplier algebras many analytic functions, such as Dirichlet space and Drury-Arv...

We consider a non-self-adjoint fourth order eigenvalue problem using a discontinuous Galerkin (DG) method. For high order problems, DG methods are competitive since they use simple basis functions and have less degrees of freedom. The numerical implementation is much easier compared with classical finite element methods. In this paper, we propose an interior penalty discontinuous Galerkin metho...

In this paper, mesh-free element free Galerkin (EFG) method is extended to solve two-dimensional potential flow problems. Two ideal fluid flow problems (i.e. flow over a rigid cylinder and flow over a sphere) have been formulated using variational approach. Penalty and Lagrange multiplier techniques have been utilized for the enforcement of essential boundary conditions. Four point Gauss quadra...

Finite field multiplier is widely applied in many domains such as coding theory and cryptography. In this paper, it is purposed to propose a concurrent all-cell error detection semi-systolic polynomial basis multiplier based on coding theory which can realize high-speed calculation and high efficient error detection with low resource consumption. First, our method is created to choose an apprec...
