Computer Simulation
Computer simulation is the running of a mathematical model on a computer, the model being designed to represent the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering. Simulation of a system is represented as the running of the system's model. It can be used to explore and gain new insights into new technology and to estimate the performance of systems too complex for analytical solutions. Computer simulations are realized by running computer programs that can be either small, running almost instantly on small devices, or large-scale ...

Computational Fluid Dynamics
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid dynamics, fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by Boundary value problem#Boundary value conditions, boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulence, turbulent flows. Initial validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed Closed-form solution, analytical or Empirical research, empirical analysis of a particular problem can be used for compa ...

Ns (simulator)
ns (from network simulator) is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns-3. All are discrete-event computer network simulators, primarily used in research and teaching. History ns-1 The first version of ns, known as ns-1, was developed at Lawrence Berkeley National Laboratory (LBNL) in the 1995-97 timeframe by Steve McCanne, Sally Floyd, Kevin Fall, and other contributors. This was known as the LBNL Network Simulator, and derived in 1989 from an earlier simulator known as REAL by S. Keshav. ns-2 Ns-2 began as a revision of ns-1. From 1997 to 2000, ns development was supported by DARPA through the VINT project at LBL, Xerox PARC, UC Berkeley, and USC/ISI. In 2000, ns-2 development was supported through DARPA with SAMAN and through NSF with CONSER, both at USC/ISI, in collaboration with other researchers including ACIRI. Features of NS2 1. It is a discrete event simulator for networking research. 2. It provides su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NetLogo
NetLogo is a programming language and integrated development environment An integrated development environment (IDE) is a Application software, software application that provides comprehensive facilities for software development. An IDE normally consists of at least a source-code editor, build automation tools, an ... (IDE) for agent-based modeling. About NetLogo was designed by Uri Wilensky, in the spirit of the programming language Logo (programming language), Logo, to be "low threshold and no ceiling". It teaches programming concepts using Agent-based model, agents in the form of ''turtles'', ''patches'', ''links'' and the ''observer''. NetLogo was designed with multiple audiences in mind, in particular: teaching children in the education community, and for Subject-matter expert, domain experts without a programming background to model related phenomena. Thousands of scientific articles have been published using NetLogo. The NetLogo environment enables exploration of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spiking Neural Network
Spiking neural networks (SNNs) are artificial neural networks (ANN) that mimic natural neural networks. These models leverage timing of discrete spikes as the main information carrier. In addition to Artificial neuron, neuronal and Electrical synapse, synaptic state, SNNs incorporate the concept of time into their operating model. The idea is that Artificial neuron, neurons in the SNN do not transmit information at each propagation cycle (as it happens with typical multi-layer perceptron, perceptron networks), but rather transmit information only when a membrane potential—an intrinsic quality of the neuron related to its membrane electrical charge—reaches a specific value, called the threshold. When the membrane potential reaches the threshold, the neuron fires, and generates a signal that travels to other neurons which, in turn, increase or decrease their potentials in response to this signal. A neuron model that fires at the moment of threshold crossing is also called a sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NEST (software)
NEST is a simulation software for spiking neural network models, including large-scale neuronal networks. NEST was initially developed by Markus Diesmann and Marc-Oliver Gewaltig and is now developed and maintained by the NEST Initiative. Modeling philosophy A NEST simulation tries to follow the logic of an electrophysiological experiment that takes place inside a computer with the difference, that the neural system to be investigated must be defined by the experimenter. The neural system is defined by a possibly large number of neurons and their connections. In a NEST network, different neuron and synapse models can coexist. Any two neurons can have multiple connections with different properties. Thus, the connectivity can in general not be described by a weight or connectivity matrix but rather as an adjacency list. To manipulate or observe the network dynamics, the experimenter can define so-called devices which represent the various instruments (for measuring and stim ...

Meep (software)
Meep (MIT Electromagnetic Equation Propagation) is a free and open-source software package for electromagnetic simulations, developed by ''ab initio'' research group at Massachusetts Institute of Technology in 2006. Operating under Unix-like systems, it uses finite-difference time-domain method with perfectly matched layer or periodic boundary conditions for field computation. Meep supports dispersive, nonlinear and anisotropic media, and features subpixel smoothing and parallelization, as well as an embedded frequency-domain solver for steady-state fields and eigenmode expansion.
