Adaptive mesh refinement (AMR) is a state-of-the-art technique for the efficient numerical solution of partial differential equations (PDE) exhibiting multiple widely differing spatial scales. Recently, spacetree-based AMR has been established as a promising approach to structured AMR (see for example [1]). In the talk the integration of the two software modules PyClaw [2] and Peano [4] is pres...

In UMTS speech transmissions, the Adaptive Multi-Rate (AMR) speech codec is employed to allow for a dynamic assignment of data rates to individual users. The control of AMR modes is based on quality measurements of the transmission channel and aims at the maximization of speech quality by selecting the mode which is best suited to the current interference situation. In contrast to GSM, a reduct...

Keywords: Adaptive mesh refinement (AMR) WENO High order finite difference Multiscale simulations a b s t r a c t In this paper, we propose a finite difference AMR-WENO method for hyperbolic conservation laws. The proposed method combines the adaptive mesh refinement (AMR) framework [4,5] with the high order finite difference weighted essentially non-oscillatory (WENO) method in space and the t...

Southeast Asia is an area of great economic dynamism. In recent years, it has experienced a rapid rise in the levels of animal product production and consumption. The region is considered to be a hotspot for infectious diseases and antimicrobial resistance (AMR). We reviewed English-language peer-reviewed publications related to antimicrobial usage (AMU) and AMR in animal production, as well as...

We have surveyed various computational applications at Lawrence Livermore National Laboratory to determine future directions for adaptive mesh refinement (AMR) resemch and simulation technology. AMR techniques were originally developed for the numerical solution of hyperbolic equations in computational fluid dynamics. However, scientists are now beginning to extend this AIvfR methodology to new...

Drug-resistant infections caused by bacteria with increasing antimicrobial resistance (AMR) threaten our ability to treat life-threatening conditions. Tackling AMR requires international collaboration and partnership. An early and leading priority to do this is to strengthen AMR surveillance, particularly in low-income countries where the burden of infectious diseases is highest and where data ...

In this paper we present three improvements over the BergerColella’s adaptive mesh refinement (AMR) approach: adaptive clustering algorithm, conservative prolongation and restriction for cylindrical and spherical grid, and divergence-free reconstruction for AMR.

An important cornerstone in the control of antimicrobial resistance (AMR) is a well-designed quantitative system for the surveillance of spread and temporal trends in AMR. Since 2008, the Dutch national AMR surveillance system, based on routine data from medical microbiological laboratories (MMLs), has developed into a successful tool to support the control of AMR in the Netherlands. It provide...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility service companies the opportunity to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. The AMR system consists of thre...
