In July 2012 I submitted a bachelor's thesis on a machine learning topic. I designed an algorithm that I developed in Java.
Now I have found a publication (September 2012) by my supervisor with all the results of my thesis, including images, with only a thanks at the end for the "Java implementations", but all of the results and the designed algorithm were taken from my thesis. The supervisor has not added anything to what I had already written in my thesis.
For me she had to add my name as a co-author of publications. Of course the supervisor helped me in the writing of the thesis but having only revived my job in publishing, then I was expecting my name as a co-author because she has not added anything new.
What recourse do I have?
Edit1:
One problem is that my thesis, about 140 page, was written in Italian and the pubblication was in English. For this reason I suppose it's hard to write to the Journal to show him my thesis. In addition, my thesis is not published online on any official channel.
The project and the thesis was made by me and one other student with the constant help of her (supervisor). But on the publication the name is of Supervisor, Co-supervisor and one more people (i suppose this people have translated 140 italian page in 5-6 english page) but why not me?
In add now I'm in other city, in other university and now i have no bridge between my supervisor.
If i have no more contact (only an email) with supervisor is there any way to write to the person who published that? and how can I prove that content is that of my thesis?
