struggle.

last few days i haven't been able to sleep very well. partly because there's a lot of stress from school and parents, and also poor elvin has been sick so he's been coughing a lot at night. really feel bad for elvin though, because when he coughs he seems so sad. and it's been like this for almost a week now i think. trying to think how i can get some children's cough syrup... =\

talked to advisor about research the other day. he asked me to read some papers of sdp relaxation applied in communication. i found some literature on the topic. some of them are a bit old, but i thought i'd start off on the older stuff first and get a solid foundation. i know some of the general concept in this area, but there's always some small details that i didn't understand that well from some papers from last semester. so for this week, i'm going to read steven boyd and lieven vanderberghe's semidefinite programming and see if it offers anything new to my understanding.

last night's lab was rediculous. didn't get home till about 9:15. =(
