Simulation as a Scientific Instrument

CoSMoS 2012

Computer simulation approaches are starting to be used more extensively throughout scientific investigations. Some scientists, however, are skeptical about the benefits of simulation. We present computer simulation as a scientific instrument in order to explore issues of their construction and use, which we believe might increase their acceptance within science. We highlight the need to underst...

An Instrument for What? Digital Computers, Simulation and Scientific Practice

Rule-based of Monetary Policy in Iran Inspired by McCallum Rule

Economists have reached a consensus that an independent central bank could improve its policy efficiency by following a monetary policy rule. One of the important rules is McCallum rule where that requires central banks to target the growth rate of nominal GDP using the monetary base as its instrument. One of the features of the McCallum rule uses the monetary base rather than the interest rate...

Developing CIMA based Remote Access for Collaborative e-Research

An infrastructure for remote instrument access, data acquisition and data management is being developed for e-Research. The Common Instrument Middleware Architecture (CIMA) is being used to provide a scalable and extensible basis for the cyberinfrastructure, and X-ray diffraction is targeted as an ideal development domain. Australian research is enhancing the CIMA model to enable the use of fed...

Sound Generation by a Turbulent Flow in Musical Instruments - Multiphysics Simulation Approach -

Total computational costs of scientific simulations are analyzed between direct numerical simulations (DNS) and multiphysics simulations (MPS) for sound generation in musical instruments. In order to produce acoustic sound by a turbulent flow in a simple recorder-like instrument, compressible fluid dynamic calculations with a low Mach number are required around the edges and the resonator of th...
