This paper analyzes stability and convergence properties of a conjugate heat transfer problem in one space dimension. The energy method is used to derive boundary and interface conditions and to prove that the semi-discrete problem is stable. The numerical scheme is implemented using 2nd-, 3rdand 4th-order finite difference operators on Summation-By-Parts (SBP) form. The boundary and interface ...

This work focuses on high-order numerical schemes for conservation laws with emphasis on problems that admit discontinuous solutions. We will investigate several enabling techniques with the aim to construct robust methods for unstructured meshes capable of reliably producing globally high-order accurate results even in the presence of discontinuities. We use spectral and pseudo-spectral scheme...

In this paper we present an algorithm for narrowing the constraint y = e x. The algorithm has been designed to be fast by using only IEEE multiplication. The main diiculty is to design algorithms which soundly, rapidly, and precisely compute upper and lower bounds on e x and ln(y). We prove that our algorithms are correct and produce upper and lower bounds which diier by at most 2 ULP. Experime...
