Unreferenced date June 2008 In computer science, a simulation is a computation of the execution of some appropriately modelled state transition system. Typically this process models the complete state of the system at individual points in a discrete linear time frame, computing each state sequentially from its predecessor. Models for computer programs or VLSI logic designs can be very easily simulated, as they often have an operational semantics which can be used directly for simulation. Symbolic simulation is a form of simulation where many possible executions of a system are considered simultaneously. This is typically achieved by augmenting the domain over which the simulation takes place. A symbolic Variable programming variable can be used in the simulation state representation in order to index multiple executions of the system. For each possible valuation of these variables, there is a concrete system state that is being indirectly simulated. Because symbolic simulation can cover many system executions in a single simulation, it can greatly reduce the size of verification problems. Techniques such as symbolic trajectory evaluation STE and generalized symbolic trajectory evaluation GSTE are based on this idea of symbolic simulation.

Learners take on the role profiles of specific characters or organisations in a contrived setting. Roleplay is designed primarily to build first person experience in a safe and supportive environment. Roleplay is widely acknowledged as a powerful teaching technique in face to face teaching and roleplay online is also powerful, with some added benefits. Development When we are young, we learn by mimicking, playing, and experimentation. As our language skills develop and formal schooling kicks in, these strategies are replaced by language based learning, which can dampen our curiosity and motivation to learn. Roleplay simulation aims to revive the ease and joy of experiential learning. Roleplay simulation models human interactions allowing the players to roleplay in a constructed environment by creating an artificial social structure or simulating some known social structure enforcing the social structure providing plausible scenarios for players to respond, react and enrole to. Online roleplay simulation Online roleplay simulation, or Role Playing Game RPG , has nothing to do with teaching. It is modeled on the assumption that human interactions are communicative events.

Cleanup date April 2009 Historical simulation in finance s value at risk VaR analysis is a procedure for predicting value at risk by simulating or constructing the cumulative distribution function CDF of assets returns over time. Unlike most parametric VaR models, Historical Simulation does not assume any distribution on the asset returns. Also, it is relatively easy to implement. However, there is a couple of shortcomings of historical simulation, and first of all is that it imposes a restriction on the estimation assuming asset returns are independent and identically distributed random variable independent and identically distributed iid which is not the case. From empirical evidence, it is known that asset returns are clearly not independent as they exhibit certain patterns such as volatility clustering . Therefore it can be unrealistic to assume iid asset returns. Second restriction relates to time. Historical simulation, it applies equal weight to all returns of the whole period and this is inconsistent with the nature where there is diminishing predictability of data that are further away from the present. These two shortcomings leads economists and financial experts to further develop other non parametric, semi parametric and parametric models. Weighted historical simulation Like the traditional historical simulation technique, weighted historical simulation applies decreasing weights to returns that are further away from the present, which overcomes the inconsistency of historical simulation with diminishing predictability of data that are further away from the present. However, weighted historical simulation still assumes iid asset returns. ref cite journal last Boudoukh first J. coauthors Richardson, M., Whitelaw, R. title The Best of Both Worlds journal Risk year 1998 volume 11 pages 64 67 url http pages.stern.nyu.edu rwhitela papers hybrid 20risk98.pdf ref Filtered historical simulation Filtered historical simulation is a semi parametric technique in forecasting ... more details
Unreferenced date December 2009 In theoretical computer science a simulation preorder is a Relation mathematics relation between state transition system s associating systems which behave in the same way in the sense that one system simulates the other. Intuitively, a system simulates another system if it can match all of its moves. The basic definition relates states within one transition system, but this is easily adapted to relate two separate transition systems by building a system consisting of the disjoint union of the corresponding components. Formal definition Given a state transition system labelled state transition system S, , , a simulation relation is a binary relation R over S i.e. R S × S such that for every pair of elements p, q S, if p,q R then for all , and for all p S, math p overset alpha rightarrow p math implies that there is a q S such that math q overset alpha rightarrow q math and p ,q R. Equivalently, in terms of relational composition math R 1 overset alpha rightarrow quad subseteq quad overset alpha rightarrow R 1 math Given two states p and q in S, q simulates p, written p q if there is a simulation R such that p, q R. The relation is a preorder , and is usually called the simulation preorder . It is the largest simulation relation over a given transition system. Two states p and q are said to be similar if p simulates q and q simulates p . Similarity is an equivalence relation , but it is coarser than bisimilarity . Similarity of separate transition systems When comparing two different transition systems S , , and S , , , the basic notions of simulation and similarity can be used by forming the disjoint composition of the two machines, S, , with S S S , and , where is the disjoint union operator between sets.

Dynamic simulation is the use of a computer program to model the time varying behavior of a system. The systems are typically described by ordinary differential equations or partial differential equations . As mathematical model s incorporate real world constraints, like gear backlash engineering and rebound from a hard stop, equations become nonlinear. This requires numerical methods to solve the equations. A numerical simulation is done by stepping through a time interval and calculating the integral of the derivatives by approximating the area under the derivative curves. Some methods use a fixed step through the interval, and others use an adaptive step that can shrink or grow automatically to maintain an acceptable error tolerance. Industrial uses of dynamic simulation are many and range from nuclear power, steam turbines, 6 degree of freedom vehicle modeling, electric motors, econometric models, biological systems, robot arms, mass spring dampers, hydraulic systems, and drug dose migration through the human body to name a few. These models can often be run in real time to give a virtual response close to the actual system. This is useful in process control and mechatronic systems for tuning the automatic control systems before they are connect to the real system, or for human training before they control the real system.

Unreferenced date December 2009 Orphan date February 2009 Fiber simulation is a branch of mechanics that deals with modeling the dynamics mechanics dynamics and rheology of particles of large aspect ratio, or fibers with the goal of predicting the properties of fiber suspensions and networks based on first principles . Simulation of fiber suspensions have applications in paper industry and also in composites , including composites made of carbon nanotubes . Many of the models used to simulate fibers were developed by researchers in the field of rheology . Rheologically speaking fiber suspensions are non Newtonian fluid s, and can display normal stress differences. Early fiber simulations employed particles which were rigid rods or prolate spheroids , whose equation of motion equations of motion have analytical solutions. More recent models are able to represent flexible fibers. The models rely heavily on continuum mechanics concepts and the numerical methods employed have some similarities to those employed in molecular dynamics , or in dynamics of multi body systems. The use of computers facilitates greatly the solution of fiber simulation problems. The complexity of the simulations arise from the system having a large number of degrees of freedom physics and chemistry degrees of freedom , and from the numerous possible interparticle interactions having place, such as friction , hydrodynamic interactions, and other kinds of interparticle forces such as colloidal forces that exert attractive or repulsive forces.
