October 20, 2007. Doujinshi manga (often shortened to doujin) are non-professional and/or self published comics. Doujinshi manga can be broken into two broad categories: fan-comics and original works. Fan-comics, much like fan-fiction, are based on established properties and created by fans of those properties. Original works are based on the doujinshi-ka's (creator) original ideas.
What is Purchasing Power Parity (PPP)? Why is it important? Purchasing power parity (PPP) is an economic term that calculates the relative value of different currencies.
A few notes on using this PPS signal: 1  There are two measures of the signal: one is the signal accuracy and the other is its precision. Accuracy is how close the signal edge is to the actual UTC boundary. 2  The PPS signal edge and rise time are very important if you are using it to reset a counter. If the rise time is slow due to a large input capacitance, long signal length, etc. this will add an offset to the accuracy that will need to be calibrated out.
