Baking Blogs Pinterest and Big Data

      Rebecca and I initially got interested in the effect that Pinterest had on baking blogs after noticing that one of BrownEyedBakers more popular recipes had an interesting timeline for the comments. The blog (http://www.browneyedbaker.com/2008/06/21/thick-and-chewy-chocolate-chip-cookies/) had a medium amount of comments when it was posted in 2008, very little in 2009, and then the number of comments steadily increased after 2010. We hypothesized that this was due to the creation and rise of Pinterest in 2010.     Below is a link to the presentation we made for our project that examined other blogs and numbers of comments on their recipes. We also looked into why this trend applied to BrownEyedBaker but not to another popular baking blog Bakerella. We used a website called PinPuff.com to calcularte the pinfluence score. This was calculated by looking at the  number of followers (reach), activity (number of pins, boards, and likes), ...

Basic data encoding techniques

To determine successful receiving of data we should have consider 3 major factors, they are   S/N � increase of this signal to noise ratio decreases the bit error rate.    Data rate � increase of data rate increases the bit error rate.   Bandwidth � increase of bandwidth tends to increase of bit error rate. We use data encoding to increase the success fulness of the receiving signal. There are four encoding schemes        Analog data � Analog signal (telephone)   Analog data � Digital signal (CODEC)   Digital data � Analog signal (Modem)   Digital data � Digital signal (Digital transmitter) Analog data � Analog signal �          Amplitude modulation (uses in fiber optics)             In this method we varied carrier signal�s amplitude according to the amplitude of modulating signal but the frequency remains unchanged. This is sim...
