Police refuse to return Chen s personal computer and cell phone.

Arash Abadpour, a Canada based Iranian blogger and computer scientist explained the situation to Global Voices as following

I actually drew that up on a little crummy Mac computer in my attic at my house, and one of the many designs which they have now is still the same design I drew way back when.

In 3D computer graphics, 3D modeling (or modelling) is the process of developing a mathematical representation of any three dimensional surface of an object (either inanimate or living) via specialized software.

I've taken inputs on positions and so forth, run it through a computer model that had simulated the dynamics of interaction, and these are the simulated dynamics, the predictions about the path of policy.

The fact that these models give equivalent classes of computable functions stems from the fact that each model is capable of reading and mimicking a procedure for any of the other models, much as a compiler is able to read instructions in one computer language and emit instructions in another language.
