Hello,
If both the branch name is not showing in any web page or paper, that means that college might not be providing those courses in graduation. It is not necessary for a college to provide all the engineering branches in graduation. They try to inculcate one by one and expand it. They might do it in future. If you want to read instrumentation engineering or biomedical engineering then you can go for EIE and look for colleges who provide this degree in BTech level according to the entrance also. It always not mandatory that the college you choose will accept the entrance you appeared.
Hope it helps!
