3d Framework C# Winforms for micromechanics simulation

i'm currently making some software to assist our experiments with writing 3d microstructures into glasschips using a femtosecond laser. It would be of great help to have a simulator for the structures before actually writing them. I'm sure there is…

Open source motion-capture software

Is there any open source software to map points on the human body to a simulated 3D model? Something like they do in some movies to map the movement of actors onto 3D models. What do they use? Are there any open initiatives for a wider audience in…

C vs. C++ for numeric simulation (performance)

I am about to write an off-lattice diffusion limited aggregation (DLA) simulation and I am wondering whether to use C or C++. C++ would be nice for design reasons but I am wondering if C would perform better. Of course I know about algorithm…

how to simulate correlated binary data with R?

Supposing I want 2 vectors of binary data with specified phi coefficients, how could I simulate it with R? For example, how can I create two vectors like x and y of specified vector length with the cor efficient of 0.79 > x = c(1, 1, 0, 0, 1, …

Tutorial on stochastic simulation in Haskell

I'd like to use Haskell for stochastic simulation, but I don't know how. I've read Hutton's 'Programming in Haskell', and I'm comfortable writing deterministic functional programs. However, I don't know how to start writing stochastic simulations of…

VHDL alternative submodule architecture for simulation

I have a VHDL component which implements a DRAM test sequence. It contains a child entity which is the DRAM controller. I want to simulate (debug) the DRAM test sequence but use a simple fake stub for the DRAM controller rather than the real,…

Making a more efficient monte carlo simulation

So, I've written this code that should effectively estimate the area under the curve of the function defined as h(x). My problem is that i need to be able to estimate the area to within 6 decimal places, but the algorithm i've defined in estimateN…

Controlling events in a hybrid Modelica model

I am confused by the hybrid modelling paradigm in Modelica. On one hand, events are useful, on the other hand, they are to be avoided. Let me explain my case: I have a large model consisting of multiple buildings in a neighborhood that is…

Discrete fluid "filling" algorithm for a height map

I am looking for an algorithm that will describe the transient behaviour of a fluid as it spreads across the surface of a height map. My starting conditions at t=0 are: A 2D matrix of height values (H) of size [x, y] A 2D matrix of fluid height…

Find the best game tactic against an other tactic, for example in the card game Toepen

I want to test some card game tactics against each other, my goal is to know witch tactic would be better in real live. To do this I made a simulation, but I don't know if I made a good one. So I would like to know how to create a good…

Simple Discrete event simulation library (C++) for process/task scheduling?

Simple question: I built a quasi-processor simulator that takes a precedence graph, determines priorities (and "ready" instructions), schedules the tasks on available functional units, etc. Pretty much a very basic simulator. But I realized I…

Controlling memory allocation/GC in a simulation?

I'm having a bit of trouble figuring out how to reduce memory usage and GC time in a simulation running in the State monad. Presently I have to run the compiled code with +RTS -K100M to avoid stack space overflow, and the GC stats are pretty…

L1 and L2 Miss Rates in SimpleScalar Simulation

I have simulated 4 different binaries in the SimpleScalar simulation tool and for every binary the L2 unified miss rate is greater than L1 data miss rate. In my assignment I am suppose to do some analysis. First thing that come to my mind is L2 miss…
