As a researcher/developer in the field of mechanical engineering, I am looking for a wiki.
The purpose of the following question is to convince my colleagues and managers to introduce a wiki, based on the look and feel of examples.

Can anyone provide examples of active wiki instances that satisfy the following requirements (in order of importance, more or less):

- math content: lots of mathematical formulas, generated with a Latex plug-in,
- image content: lots of vector-based image content (e.g. *.svg)
- (optional) cross-reference content: captions, cross-references to figures / tables / equations,
- topic: research and/or development in the field of engineering,
- version: a more recent wiki engine version,
- status: active participation of many individuals,
- language: English,
- user type: academic or corporate,

Thanks in Advance!

Regards,

Johan
