This lets you scan the articles on the page more efficiently. Sometimes you'll even spot more headlines that you might never have seen buried on the original page. Don't feel badly if you haven't heard of RSS -- you may have already come into contact with it without knowing its name. Some Web-browsing software automatically detects RSS feeds. Firefox and Opera display the now-common square orange badge for a Web feed in the browser's address bar when they find RSS feeds on a site. You'll see a similar symbol in Internet Explorer's toolbar. Safari shows a blue rectangle with "RSS" written in white letters. Those emblems show the presence of active RSS feeds on a site to help you get started. Click on one, though, and you'll get a list of options which may seem a little intimidating if you don't know what they mean. Some sites have multiple feeds for the same page with different versions of RSS or a competing standard, Atom.|Ukraine’s most prolonged and deadly crisis since its post-Soviet independence began as a protest against the government dropping plans to forge closer trade ties with the European Union and has since spurred a global standoff between Russia and Western powers. The crisis stems from more than twenty years of weak governance, a lopsided economy dominated by oligarchs, heavy reliance on Russia, and sharp differences between Ukraine’s linguistically, religiously, and ethnically distinct eastern and western halves. After the ouster of President Viktor Yanukovich in Feburary 2014, Russian moves to take control of the Crimean Peninsula signaled Moscow’s intent to retain its sphere of influence and raised serious questions about the ability of the state’s new leaders to provide stability and a path to meaningful reforms. Why is Ukraine in crisis? The country of forty-five million people has struggled with its identity since it gained independence with the dissolution of the Soviet Union in 1991. Ukraine has failed to resolve its internal divisions and build strong political institutions, hampering its ability to implement economic reforms, overcome corruption, and lessen the sway of powerful oligarchs. There is a growing trend of courses and academic conferences being held online with available online video sources. However, a major challenge with the emergence of large-scale online resources is how to effectively retrieve and present the desired video contents from numerous resources for end users. For example, when users want to search for a specific technique in an academic conference, they will likely get several results after typing a keyword. The current video retrieval systems do not provide a satisfactory interaction. Summarization function for saving the user’s time. The hierarchical visual interface consists of a video layer that contains video and groups of slides with timestamps, a frame layer that contains the speech content and visual content of one selected slide, and a poster layer that demonstrates the summarized video in a poster style. This interface can fulfill the diverse usage scenario for different users. The first scenario is that when users want to see an overview of a specific video, they can enter the poster layer.The second scenario is that when users only want to view a specific part of the video, they can click the title in the poster layer to redirect them to the corresponding video layer.The third scenario is that when users want to view the textual matter of the speech content or the slide rather than the video, they can enter the frame layer. india news
