Publishing policies - copyright transfer
You can publish the preprint online, e.g. on arXiv, RG, or your university preprint server. 

If your paper is accepted in the journal, you probably will be asked to transfer the copyright to the journal. The copyright applies to the accepted version of the paper, i.e. after reviewers' suggestions are implemented, the paper is proofread, copy-edited and typeset in journal style. According to SHERPA/RoMEO, you can upload a post-print version to your own website immediately, and any other website 12 months after the acceptance.

If your paper is not accepted by the journal, you are free to make it available anywhere on the web.
