### concept | framework:

Simulation
* detailed and mathematically sound tool for analysing and predicting system behavior.
* follows development.
* form of information processing.
* has negative values
* includes examples.
* involving circuit behaviour are examples of deterministic systems.
* is an area in which the application of computers seems highly appropriate
  - implementation of theory
  - important aspect of modern statistical computing
  - techniques
* is the act of capturing an actual or proposed system in a software model
  - process of eliciting and observing a model's behavior over model time
* makes assumptions.
* particular type of modelling.
* play a variety of roles in science in general and computer science in particular.
  * are very useful all over the world, because in a simulation things can be controlled that might not be easy to control in real life. They can use or smaller versions of an object or system for testing or practice. They can often use smaller versions of things, like space ships or rooms, to simulate the real thing. They can also use a safer thing in place of a thing that is dangerous, like when astronauts practice in a swimming pool rather than in outer space. Astronauts also practice in simulations of the moon before they went and landed there, and in simulations of spaceships that move the way real spaceships do, so they can get used to it. Simulations often use computers or television. Computers are used to make simulations of what a spaceship's route might be on the way to the moon, to help plan the mission.
* plays an increasingly critical role in all areas of science and engineering.
* process of analyzing a design model using mathematical techniques
  - that uses a computer to design a model of a real system
* provides information
  - insight
  - new insight
  - useful information
* requires types.
* shows forces
  - outcomes
* type of software which integrates the cognitivist approach.
* uses a computer to model, and thus understand, the behavior of a system.
* way to approximate real-world processes.
* widely-used technique for building realistic models of complex systems.

### concept | framework | simulation:

Numerical simulation
* are the main means of research because direct experiments are impossible.
* can help interpret remote sensing data of the ocean surface.
* compare the way of phase space exploration of different genetic operators.
* deals with the modelling of a physical situation on a computer.
* fill a gap between physical experiments and analytical approaches.
* is an important and widely used tool in many areas of condensed matter physics
  - used to predict fire growth within the compartment of origin
* method of current interest for predicting particulate flows.

War game
* Many war games use hexagonal grids instead of square grids.
* are simulation.

### concept | framework:

Truss
* are a series of triangles fastened together with gusset plates
  - an engineered built roof system that can span large areas without support in the middle
  - bandages
  - beams arranged to form triangles
  - frameworks
  - load
  - located in buildings
  - medical devices
  - wood with a plywood covering and fiberglass shingles
* can support large loads without adding too much to the overall mass of an object.
* minimize cutting and framing on the job site, greatly reducing labor cost.
* tend to be a stronger lighter and less expensive approach to roof framing.

### concept | framework | truss:

Steel truss
* are unaffected by termites.
* cross at angles overhead.

Undercarriage
* are frameworks
* is as clean as the body

Valance
* lighting using fluorescent fixtures gives good lighting without a visible source.
* pouf style.
