Q: Title: Kalman filters, Brown & Hwang vs. Gelb Review: This is not my favorite text on Kalman filters. I find there is too much emphasis on elementary, preliminary material, and not enough on application.I teach the subject out of my own notes (draft book) where the development follows that of Gelb, Applied Optimal Estimation, and all of the computations are done in Matlab. I first read Kalman's original papers in great detail, and rederived his work before the Gelb book (MIT Press, 1974) was published. Since the advdent of Matlab (1984) I have continued to used Gelb's derivations, and augmented that work with extensive Matlab examples.I still find Gelb more usable as a text than other, newer books, and will continue to use it along with my Matlab supplements.

Q: Title: Love this product Review: This product works wonders in controlling frizz and defining my curls. I dry my shoulder-length hair first with a microfiber towel (scrunch upwards, no rubbing or wrapping). Then rub a quarter size portion between my hands and scrunch it onto my hair. Then I pull it through all the strands, place a few horizontal clips at the top to help hold some lift and dry with a diffuser to bring out the curls. Once completely dry, I break up the stiffness by just scrunching the hair upwards. That breaks the "gel cast" or stiffness some reviews complain about. I'm left with soft, well-defined curls. Order the book: "Curly Girl: The Handbook by Lorraine Massey and Michele Bender" and learn this and other life-changing techniques for curly hair. Is this product review negative?

A: No


Q: Title: Loved the show, Love the music Review: OMG!!! I've known about Cirque Du Soleil but never had the chance to see it until my mother bought me tickets to see Alegria when it came to town and I am so grateful she did. The show was amazing I couldn't leave without buying the dvd and I have watched it everynight since. The music is perfert it's my favorite mix and style, it's one of those cd's that you can listen to over and over again and never get tired of it. The music is powerful and really lets you escape into that world. There isn't a bad thing to say about Cirque Du Soleil!!!!I'm hooked... Is this product review negative?

Q: Title: Should be Free Review: I don't think this movie is worth one dollar. It does have useful information, but if the intent is to help the people save the planet, then why not just give it away, and ask for donations.There are a lot of moments in this film that I thought were totally irrelevant, and focused on the life of Al Gore.I feel like I got tricked by all of the positive reviews into contributing to a campain for Al Gore.Don't pay for this film!
