For a pair of integers 0 < t < r , the t-chromatic number of an r-uniform hypergraph H =( V , E ) is the minimal k , for which there exists a partition of V into color classes U1 ,..., Uk such that every edge of H intersects every color class in at most t vertices . The RealNetworks / SanDisk partnership will feature groundbreaking new features embedded in a line of SanDisk 's Sansa e200 series of portable players . Actually , we define in FO + IFP a linear ordering on arbitrary SE finitely branching graphs which may be infinite and so represent a more general class of hereditarily-finite non-well-founded sets HFA ^ { \ infty } ( with infinite transitive closure ) . A more detailed look suggests that the Internet is succeeding largely for the same reasons that led the PC to dominate the mainframe , and are responsible for the success of Microsoft . When you use push or pull splitting , setting a low forward error correction rate ( FEC ) may cause error correction packets to arrive after the receiver has transmitted the contents of its data buffer to its connected clients . Rhapsody 's breakthrough in free , legal music sharing was made possible by several factors : First , Real worked closely with the music industry to create a more flexible model for consumers to try Rhapsody for free . Recognising the demand for a more personalised and interactive approach to music consumption , RealMusic incorporates advanced search technology that allows subscribers to explore thousands of Internet radio stations from around the world , categorised by language , country or genre . The national trend , however , has been toward a more formal process than was being used at USU which has relied on written policy for this acknowledgment . A flexible scheme should allow for packages of various sizes to be offered , from a single program up to all the programs . To every EFF we assign a pair of hypergraphs , representing clique covers of two associated graphs , and obtain some necessary and some sufficient conditions for the stability of EFFs in terms of graph-properties . Audio packets are much smaller than video packets , so when you stream audio-only clips , you generally do not need to increase the buffering time on the receiver when using a low error correction rate .
