Abstract: Systems and methods are provided for personalizing new song suggestions for a user. A plurality of users provides thumbs up and thumbs down ratings for a pair of songs (song A and B). A first aggregate rating for song B is calculated based on ratings given to song A by all of the users that gave a like rating to song A. Similarly, a second aggregate rating is calculated for song B based on ratings given to song B by all users that gave a dislike rating to song A. Then a user that has not previously rated song B, supplies a rating for song A. A prediction is performed of how the user will rate song B based on the user's rating of song A. For example, the first aggregate rating for song B is used if the user rated song A positively.

Abstract: A scroll compressor includes fixed and orbiting scrolls. The fixed scroll includes a fixed scroll end plate and a spiral fixed wrap extending from the end plate. The orbiting scroll includes an orbiting scroll end plate and an orbiting wrap extending from the end plate and engaging with the fixed wrap to form compression chambers. The fixed wrap includes a first fixed wrap portion on a radially outer side and a second fixed wrap portion on a radially inner side. The first fixed wrap portion is periodically covered by the orbiting scroll end plate and the second fixed wrap portion is always covered by the orbiting scroll end plate while the scroll compressor is operating. A sealing member is provided on one of the first fixed wrap portion and a first covering portion of the orbiting scroll end plate corresponding to the first fixed wrap portion.
