Many compressible ow and aeroacoustic computations rely on accurate nonre ecting or radiation boundary conditions. When the equations and boundary conditions are discretized using a nite-di erence scheme, the dispersive nature of the discretized equations can lead to spurious numerical re ections not seen in the continuous boundary value problem. Here we construct discretely nonre ecting bounda...

This paper analyses Rawls’s celebrated di¤erence principle, and its lexicographic extension, in societies with a …nite and an in…nite number of agents. A uni…ed framework of analysis is set up, which allows one to characterise Rawlsian egalitarian principles by means of a weaker version of a new axiom the Harm Principle recently proposed by [13]. This is quite surprising, because the Harm princ...

A …rst-order linear di¤erence system under rational expectations is, AEyt+1jIt = Byt +C(F)ExtjIt; where yt is a vector of endogenous variables; xt is a vector of exogenous variables; Eyt+1jIt is the expectation of yt+1 given date t information; and C(F)ExtjIt = C0xt+ C1Ext+1jIt + ::: + CnExt+njIt. Many economic models can be written in this form, especially if the matrix A is permitted to be si...

In this paper, the new set di§erence is deÖned between interval- ued intuitionistic fuzzy sets (IVIFSs).A di§erent perspective reduced to formal IVIFSs. This difference IVIFSs introduced by using : operation. Instead of comparing operator with all other operations, operation which defined \ used. Some fundamentel properties are provided and not on examined whether satisfy or alpha-operation. By...

We compare between the binary congestion indication scheme and the explicit rate indication scheme proposed for congestion control of ATM's available bit rate service (ABR). The fairness problems of the binary congestion indication scheme that arise when mixing long and short distance tra c are investigated. Our simulations suggest that the unfairness noticed in this case towards the long dista...

This chapter is dedicated to the de nition of relevant sets of shapes and that of de ning a metric on them. Following a recent research monograph by Delfour and Zolesio [33], we consider the characteristic functions of the subsets of R2 and their distance functions. The L2 norm of the di erence of characteristic functions, the L∞ and the W 1,2 norms of the di erence of distance functions de ne ...

In this paper we present a bottom-up algorithm called MRI to induce logic programs from their examples. This method can induce programs with a base clause and more than one recursive clause from a very small number of examples. MRI is based on the analysis of saturations of examples. It rst generates a path structure, which is an expression of a stream of values processed by predicates. The con...

In analogy with transition equations for type Schubert polynomials given by Lascou and Schutzenberger s 14 , we give recursive formulas for computing representatives of the Schubert classes for the isotropic ag manifolds. These representatives are e actly the Schubert polynomials found in 2 . This new approach to nding Schubert polynomials is very closely related to the geometry of the ag manif...

Non-rigid registration can automatically quantify small changes in volume of anatomical structures over time by means of segmentation propagation. Here we use a non-rigid registration algorithm based on optimising normalised mutual information to quantify small changes in brain ventricular volume in MR images of a group of ve patients treated with growth hormone replacement therapy and a contro...
