How to Make Simpler GMRES and GCR More Stable
In this paper we analyze the numerical behavior of several minimum residual methods, which are mathematically equivalent to the GMRES method. Two main approaches are compared: the one that computes the approximate solution (similar to GMRES) in terms of a Krylov space basis from an upper triangular linear system for the coordinates, and the one where the approximate solutions are updated with a...
متن کاملHow to Make AADL Specification More Precise
AADL (Architectural Analysis and Design Language) is a textual and graphical language used to design and analyze software architecture of embedded real time systems. Many tools and models provide semantics and precise meaning for AADL architecture behavior. However, they are not supported by a well defined formal semantics. This paper suggets Rewriting Logic via its practical language Maude as ...
متن کاملHow to Make Assured Service More Assured
In this paper, we study why the current assurance services (AS) architecture with pro lers/markers at edge routers and with queue management mechanisms (RIO) at core routers cannot achieve throughput assurance and fairness. Based on the ndings of the simulation study, we propose an enhanced version of the time sliding window (TSW) pro ler, called the enhanced TSW (ETSW). We also design two enha...

متن کاملHow to Make Lisp More Special
Common Lisp provides generalized places that can be assigned via the SETF macro, and provides ways to hook into SETF. Past attempts to extend this to rebinding places, similar to “special” variables, lead to potentially incorrect behavior: New “bindings” are created by side effects, and therefore affect all threads that access the same places. Instead of storing values directly we can store sym...
