What is a Simulation Model?

Juan M. Durán
2020 Minds and Machines  
The core claim presented here is that simulation models are rich and complex units of analysis in their own right, that they depart from known forms of scientific models in significant ways, and that a  ...  Many philosophical accounts of scientific models fail to distinguish between a simulation model and other forms of models.  ...  Acknowledgements Thank are due to Björn Schembera for discussions on the architecture of simulation models, and to Johannes Lenhard and Nico Formanek for their close reading of the article.  ...

András Rigler, Eszter Bartha
2006 Review of Sociology  
The paper introduces a simulation, which was developed by Michael Krassa to model the opinion contagion.  ...  The problem is that the model helps little to give a better forecast because we have no data about the threshold values and we do not know the point where the dynamics of the opinion contagion stands at  ...  Review of Sociology 12 (2006) OPINION CONTAGION: WHAT IS TO BE LEARNT FROM A SIMULATION MODEL?  ...

What Is It Like to Be a Brain Simulation? [chapter]

Eray Özkural
2012 Lecture Notes in Computer Science  
We frame the question of what kind of subjective experience a brain simulation would have in contrast to a biological brain. We discuss the brain prosthesis thought experiment.  ...  We evaluate how the experience of the brain simulation might differ from the biological, according to a number of hypotheses about experience and the properties of simulation.  ...  It is more similar to vision, because it helps build a model of the scene around us, however, instead of stereoscopic vision, the bat sonar can make accurate 3-D models of the environment from a particular  ...

What is the Trade-Off between Snowpack Stratification and Simulated Snow Water Equivalent in a Physically-Based Snow Model?

Julien Augas, Kian Abbasnezhadi, Alain N. Rousseau, Michel Baraer
2020 Water  
For a multilayer, physically-based snow model like MASiN (Modèle Autonome de Simulation de la Neige), the number of modeled snow layers can affect the accuracy of the simulated SWE.  ...  Nevertheless, from a performance standpoint, SWE modeling can be accurate enough with a MNSL of two (2), with a substantial performance drop for a MNSL value of around nine (9).  ...  Discussion and Conclusions Simulated SWE values are the main criteria when evaluating the performance of a snow model, whether it is used as a standalone module or as part of a hydrological model.  ...

What You Simulate Is What You Synthesize: Designing a Processor Core from C++ Specifications

Simon Rokicki, Davide Pala, Joseph Paturel, Olivier Sentieys
2019 2019 IEEE/ACM International Conference on Computer-Aided Design (ICCAD)  
In this work, we highlight the gain of starting from a unique high-level synthesis and simulation C++ model to design a processor core implementing the RISC-V Instruction Set Architecture (ISA).  ...  The specification code is used to generate both the hardware target design through High-Level Synthesis as well as a fast and cycle-accurate bit-accurate simulator of the latter through software compilation  ...  As we want to design a core with a performance level close to what is achievable with an HDL, we designed an explicitly pipelined simulator.  ...

Assessing what is needed to resolve a molecular phylogeny: simulations and empirical data from emydid turtles

Phillip Q Spinks, Robert C Thomson, Geoff A Lovely, H Bradley Shaffer
2009 BMC Evolutionary Biology  
Determining how much additional data might be required to eventually recover most or all nodes with high support is an important pragmatic goal, and simulations have been used to examine this question.  ...  Most simulations have been based on few empirical loci, and suggest that well supported phylogenies can be determined with a very modest amount of data.  ...  Our simulation procedure is shown as a flow chart in Fig 14.  ...
