Handle control events differently depending on the state of the system
c#,winforms,simulation,simulator
Each button at any specific time shall execute some specific action depending on the state of the system. Obviously, if you try to decide the specific action depending on the multitude of different variables, you will create a lot of branching code. Such code is very difficult to write correctly...
LibGDX + Box2D rotation
MassData md = new MassData(); gives zero rotational inertia: md.I == 0 so the box doesn't rotate. If you do MassData md = body.getMassData(); you will have mass and rotational inertia according to your current density. The best way to change mass and get the correct rotational inertia - calculate...
how to simulate a traffic scenario for cars
routing,simulation,ibm-connections,city,traffic-simulation
Check out http://sumo-sim.org. It is a fully featured open source traffic simulation. You can either get a static trace of vehicle positions or you can access these values via an API and trigger re-routing in a running simulation. The documentation is at http://sumo-sim.org/wiki and you can get help at [email protected]
Generate 0 entity in a run
simulation,distribution,exponential-distribution
It's not an error to get zero. With exponential interarrival times and a rate of 3 per hour, the number of occurrences in an hour has a Poisson distribution with λ=3. The probability of getting n outcomes is e-λλn/n! which for n=0 is just under 0.05. In other words, you...

Bits change when passing wire bus to module
module,simulation,verilog,processor
You are not telling Verilog that the instruction is a binary number, so it is interpreting it as decimal. You need this: instruction = 32'b00100000000010000000000000000001; #100 //add $8, $8, $8 instruction = 32'b00000001000010000100000000100000; Additionally, you should not be putting assign statements inside an always block. If you want these to...
Is it possible to build a heatmap from point data at 60 times per second?
c++,opengl,visualization,simulation,heatmap
It is definitely feasible, probably even if the calculation are done by the CPU. Ideally you should be using the GPU. The APIs needed are either OpenCL or since you are rendering the results you might want to make use of Compute Shaders. Both techniques allow you to write a...
Bitstuffing in assembly not working as intended
c++,assembly,x86,simulation,bitstuffing
To stuff the new bit you multiply by 2 which is just a convoluted way to do a shift left. This will discard the most significant bit, so you are not discarding from the least significant position of the original value, rather, you are basically overwriting the following bit with...

Verilog Testbench constant exp and pram compilation and simulation errors
verilog,simulation,hdl,modelsim
As parameters are compile-time (technically elaboration-time) constants, you cannot have them change during the course of execution. Thus, the first error in which sob.w was set to n is not valid as n cannot be determined to be a fixed value during the elaboration phase (part of compiling the entire...
calculation of simulation time in verilog

How to code a arrival generator with a varying intensity rate
The answer is called "thinning," but requires you to know the global maximum arrival rate λmax. Generate arrivals at rate λmax, but for each generated arrival at time t, only execute the arrival event with probability λt/λmax. You can do this by generating a uniform(0,1) random number U for each...
