500px has an algorithm in place to evaluate recently uploaded photos that takes views, likes and comments into account and results in a photo's rating or 'Pulse'. [21] The higher the Pulse, the more likely a photo is to reach the site's Popular page, giving it a higher chance of being seen by other users. [22]
The news feed is the primary system through which users are exposed to content posted on the network. Using a secret method (initially known as EdgeRank), Facebook selects a handful of updates to actually show users every time they visit their feed, out of an average of 1500 updates they can potentially receive.
Volume projections enable marketers to forecast sales by sampling customer intentions through surveys and market studies. By estimating how many customers will try a new product , and how often they’ll make repeat purchases, marketers can establish the basis for such projections. . . .
OpenSocial is a public specification that outlines a set of common application programming interfaces (APIs) for web applications.Initially designed for social network applications, it was developed collaboratively by Google, MySpace and other social networks.
An image that is 2048 pixels in width and 1536 pixels in height has a total of 2048×1536 = 3,145,728 pixels or 3.1 megapixels. One could refer to it as 2048 by 1536 or a 3.1-megapixel image. The image would be a very low quality image (72ppi) if printed at about 28.5 inches wide, but a very good quality (300ppi) image if printed at about 7 ...
DSC can work in constant or variable bitrate mode. The minimum allowed bits-per-pixel (BPP) is 6 bit/px; [7]: 52 the typical BPP given on VESA's website is 8 bit/px. [8] The variable-bitrate is actually a way to temporarily disable the display link; [7]: 125 it only adds the possibility of choosing 0 bit/px. [7]: 41
Google also allows advertisers to install a pixel on their website that sends conversions to the Adwords account. This allows advertisers to target their ads to drive conversions more effectively. For most traffic, Google sends a unique identifier for each click (in a gclid parameter), allowing to determine source of conversion precisely.
Image scaling can be interpreted as a form of image resampling or image reconstruction from the view of the Nyquist sampling theorem.According to the theorem, downsampling to a smaller image from a higher-resolution original can only be carried out after applying a suitable 2D anti-aliasing filter to prevent aliasing artifacts.
