I recently came across a thesis link from National Central University (NCU), Taiwan. In this link, you could search the theses you interested. Most of the theses can be downloaded without restriction, however thoses new theses will only be released to public after 1 or 2 years. That means the theses material are about 1 or 2 years old. I think it is still reasonable, at least it provides some reference.
Bear in mind that some of the theses have restriction as shown in below.
