The simulation, which took 75 days to create on a supercomputer at NASA's Goddard Space Flight Center in Greenbelt, Maryland, depicts CO2 emissions from May 2005 to June 2007.
OOF is designed to help materials scientists calculate macroscopic properties from images of real or simulated microstructures. It reads an image, assigns material properties to features in the image, and conducts virtual experiments to determine the macroscopic properties of the microstructure.
ReSP is an MPSoC simulation platform working at a high abstraction level; components used by ReSP are based on SystemC and TLM hardware and communication description libraries. ReSP provides a non-intrusive framework to manipulate SystemC and TLM objects. The simulation platform is built using Python programming language; its reflective capabilities augment the platform with the possibility of observing the internal structure of the SystemC component models. This feature enables run-time composition and dynamic management of the architecture under analysis. The full potentialities offered by the integration among Python and SystemC are exploited, during simulation, to query, examine and, possibly, modify the internal status of the hardware models. These capabilities simplify the debugging process for both the modeled hardware architecture and the software running on it.
GNU Octave is a high-level language, primarily intended for numerical computations. It provides a convenient command line interface for solving linear and nonlinear problems numerically, and for performing other numerical experiments using a language that is mostly compatible with Matlab.
Scicos is a graphical dynamical system modeler and simulator. With Scicos you can create block diagrams to model and simulate the dynamics of hybrid dynamical systems and compile your models into executable code. Scicos is used for signal processing, systems control, queuing systems, and to study physical and biological systems. New extensions allow generation of component based modeling of electrical and hydraulic circuits using the Modelica language.
A system of symmetrically coupled identical oscillators with phase lag is presented, which is capable of generating a large repertoire of transient (metastable) “chimera” states in which synchronization and desynchronization coexist. The oscillators are organized into communities, such that each oscillator is connected to all its peers in the same community and to a subset of the oscillators in other communities. Measures are introduced for quantifying metastability, the prevalence o...
Fræser is a framework for estimating the parameters of static and dynamic errors-in-variables systems with the opportunity to compare various errors-in-variables parameter estimation algorithms via simulations. It features a graphical user interface and several examples for simultaneously estimating model and noise parameters.
The framework incorporates the following linear and nonlinear estimation methods for static and dynamic systems:
* model parameter estimation for static systems
o Koopmans method
* linear model and noise parameter estimation for dynamic systems
o (extended) instrumental variables method (XIV)
o bias-compensating least-squares method (BCLS)
o Frisch scheme (FS)
o generalized Koopmans-Levin method (GKL)
* nonlinear model parameter estimation for static systems
o nonlinear Koopmans method (NK)
o approximated maximum likelihood method (AML)
* nonlinear model and noise parameter estimation for dynamic systems
o bias-compensated least squares method (BCLS)
o nonlinear Koopmans-Levin method (NKL)
o nonlinear extennonlinear extension to generalized Koopmans-Levin method (NGKL)
