The aim of this paper is to study jumping numbers and multiplier ideals of any ideal in a two-dimensional local ring with a rational singularity. In particular we reveal which information encoded in a multiplier ideal determines the next jumping number. This leads to an algorithm to compute sequentially the jumping numbers and the whole chain of multiplier ideals in any desired range. As a cons...

This study examines the multiplier effects of the grain subsidy program in China, which is a large food self-sufficiency project that is implemented as a cash transfer program. Income multiplier effects have not been examined in the evaluation of the grain subsidy program although increasing the income of farmers is the original goal of this project. A large number of household-level observatio...

Interval arithmetic provides an e cient method for monitoring and controlling errors in numerical calculations. However, existing software packages for interval arithmetic are often too slow for numerically intensive computations. This paper presents the design of a multiplier that performs either interval or oating point multiplication. This multiplier requires only slightly more area and dela...

This paper describes the 8x8bit signed and unsigned multiplication using Modified Booth Encoding multiplier. In existing method Baugh-Wooley multiplier perform the multiplication operation only for signed numbers and it has the drawbacks of complicated to deploy an irregular reduction of trees and it consumes more area due to more number of partial products. Proposed modified Booth encoding Rad...

Introduction. Multiplier ideal sheaves were introduced by Kohn [Kohn1979] and Nadel [Nadel1990] to identify the location and the extent of the failure of crucial estimates. Such multiplier ideal sheaves are defined by a family or a sequence of inequalities instead of a single inequality. In Kohn’s definition there is one inequality for every test function (or test form) and the multiplier has t...

High speed execution of arithmetic operations and high degree of precision in real time system are of major concern in any digital signal processing (DSP). Speed of DSP depends on speed of multiplier and algorithm used. In this paper we propose Residue Number System method for fast “carry free” floating point arithmetic operations. Floating Point RNS units have obvious advantages over tradition...

In the FIR filter design the MCM block optimization plays a vital role to reduce the critical path which is due to the product accumulation section. The critical path delay is reduced by using the Transposed direct form (TDF) FIR filter is proposed. The filters which have large number of multipliers. The partial products by using OTFC-LRRS multiplier is implemented in the FIR filter. The array ...

Using census and multiplier methods to estimate the size of the population of female sex workers (FSWs) in a small city in western China, this study compared the advantages and challenges of the two methods. It was estimated that there were about 1,500 FSWs within the urban area using the census method, which was significantly lower than that estimated by the multiplier method (2,500). Each met...

in this paper, we have proposed a new iterative method for finding the solution of ordinary differential equations of the first order. in this method we have extended the idea of variational iteration method by changing the general lagrange multiplier which is defined in the context of the variational iteration method.this causes the convergent rate of the method increased compared with the var...

The mathematics models of Reliability-based Structural Optimization (RBSO) were presented in this paper, then how to handle the constraint become sixty-four-dollar question of establishing the fitness function. Based on exterior penalty function method, penalty gene is made adaptively according to population’s evolution, then the fitness function is established, which is mapping formula of obje...
