...You're asking us how to introduce yourself to someone at university? Everyone there will be in the 'I don't know anyone' boat. Just walk up to people and say hi. Job done.
With regards to women - if you are planning on grabbing yourself a girlfriend as early as possible, talk to people on the same (or similar) course and/or the same societies as you (DO NOT go after people in the same halls of residence/flat/whatever). That guarantees some similar interests - all the stereotypes are there for a reason (for example, my girlfriend is possibly more of a geek than I am. She's a mathematician).
The first couple of weeks/months will be full of new people all not knowing anyone. Don't instantly decide 'I like this girl'.
Make friends with people of both genders first. After a while, they'll be able to introduce you to people with similar interests to them, some of whom may well be of your gender of interest.
