So PLEASE IF YOU"RE NOT SERIOUS ABOUT THIS PROJECT DON"T PLACE A BID. We need someone who is committed to this project and can finish it within the required time.We already have an app just want to re-theme it for christmas, the app allows the user to create an avatar of him/her self (change face, eyes, mouth, cloths...etc)Everything is ready to start from our side, and we need it extremely soon (maximum 36 hours) it should"t take longer because the code is already there, it"s just a small re-theme.Few notes:1) We need to add the default share feature 2) We need to hide a couple of features from the current app, including in app purchases.3) We need to support retina graphics as they are not in the current version (all the proper naming has been done for the new graphics)4) A couple of minor changes

    Hi there. We have an existing iPhone application. It"s a legal application, English, and quite simple. To give you an idea: there are three tabs: "Introduction", "Member States" and "Get in touch". We will provide you with full tab and menu structure. We can provide all graphics needed (so, if you"re a developer, but not a designer - not to worry), and screenshots of the iPhone app. There are no special concerns. The app should be able to: load pages with text, load webpages in frame (wrap), show video in frame (no external link, YouTube and/or Vimeo) and, but that"s optional, get a feed of a twitter account and Facebook account. I"ve added some screens of the iPhone app. Here"s the catch: it"s urgent. Our app is currently in review in the Apple App Store. We had developed an HTML 5 Webapp, but it doesn"t function properly on all Android devices. Hence the last-minute freelance work :-). Idealiter it would be ready within a week/two weeks. So, if you"re interested, please let me know!Thank you!(In order for the project to be complete, the code must be function on a variety of devices and screen sizes and be bug/leak free).

Some Analysis of S-box based on Residue of Prime Number

In this article, we analyze substitution box (S-box) based on residue of prime number for different analysis such as graphical and analytical strict avalanche criterion (SAC), bit independent criterion (BIC), differential approximation probability (DP), linear approximation probability (LP) and nonlinearity. With the help of these results we determine the algebraic and statistical encryption strength and weakness of this S-box.
