Alex Grey was born on November 29‚ 1953 in Columbus‚ Ohio to a middle class family eventually becoming one the world’s greatest visionary artists of today. As a young kid he use to collect insects and dead animals and bury them in his backyard until he was bitten by a rabid bat. He had to endure a painful series of rabies antitoxin injections with a serum that was made of dead dried duck embryos which left a big lump under his skin. At age 10 he would watch his grandmother turn jaundice yellow and

On Measuring Available Bandwidth in Wireless Networks Andreas Johnsson Research Area Packet Systems Ericsson Research Mats Björkman The Department of Computer Science and Electronics Mälardalen University Abstract— BART is a state-of-the-art active end-to-end bandwidth measurement method that estimates not only the available bandwidth but also the link capacity of the bottleneck link. It uses a Kalman filter to give estimates in real time during a measurement session. In this paper‚ we have studied
