MIT develops lecture search engine to aid
students

post from Science Blog - on 14 November 2007 08:11:24 PM. © Science Blog -

Imagine you are taking an introductory biology course. You're studying for an exam and realize it would be helpful to revisit the professor's explanation of RNA interference. Fortunately for you, a digital recording of the lecture is online, but the 10-minute explanation you want is buried in a 90-minute lecture you don't have time to watch. A new lecture search engine developed at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) could help with this dilemma. Created by a team of researchers and students led by MIT associate professor Regina Barzilay and principal research scientist James Glass, the web-based technology allows users to search hundreds of MIT lectures for key topics.

Small Engine variable drive (reversible)

I recently saw a machine with a small gas engine that was directly coupled to a gear box looking device. The unit had one control lever which was moved to center for neutral (no output), one direction for cw output shaft rotation, and the other direction for ccw output rotation. The more the lever w
