Three down, one more to go; internship news

I'm almost finished with my project work. Today I wrote the report of my project in information security. We had to develop a system to make online train ticket purchasement possible with the necessary fraud protection. The train speculator has to be able to verify the ticket in very less time without consulting a database containing the online transactions. We developed a system based on encrypted information printed on the ticket as barcode.

For the last project we just have to work a little bit on the report. It was about testing an algoritm for on the fly pitch extraction of recorded speech. This information is needed to compress digital speech as good as possible.

I also have some news about my internship. As I told you before, I've chosen a thesis where I have to work on development and testing of a fast handover system for wireless connections on trains. I also told you I had a meeting to arrange an internship with Siemens on the same subject. Now, the prof has sent me a e-mail with the good news he has contact with Siemens and they're interested in such kind of internship. If everything goes well, I can do some work on their Chantry technology. It should cover a few days/weeks working in Herentals and do some tests with the equipment in Ghent. Normally there'll be a meeting around the 17th of July or afther the examinations. Let's hope everything goes well :-D

   As I read lately, NMBS already got wifi support on their trains lately, and it's been running on the Thalys too now...

   Well, there's always room for improvement, isn't there? :-p

   They only told on the newspapers they're going to do some tests. Our project, where I'll be a small piece in, is in collaboration with NMBS. So maybe they announce just that they'll start the project, with us.
   
   At the Thalys, there's communication by satellite, with an antenna on top of one of the waggons. So they have a broadband connection, but a very slow one because of the huge round trip time between the train, by satellite, to the ground station. You can't develop interactive applications on that.
   
   With the ground-antenna technique, you have a broadband connection (there'll be more than one antenna on the train connected to multiple antenna's on the ground so there's no single-antenna-bottleneck) that can be used for interactive applications. Another master thesis in the same project is development of a train application: the train will be modeled as an object of wich you can request certain parameters. From the ground station, you can control the status of the doors for example. Sending such a request, where you expect some kind of answer in real time, is not feasable.
