Scalable Streaming Adaptive Streaming has a good potential to replace widely used progressive download. Adaptive streaming can dynamically adjust the video bit-rate to the varying available bandwidth and prevent prefetching too much future video data when the extra bandwidth is available but the data are eventually left unused. For adaptive streaming, video servers need to maintain multiple copies of the same video with different bit-rates for different clients and clients with different kinds of connectivity, which requires additional server storage and reduces cache hit ratio. Recently, Scalable Video Coding (H.264/SVC) is considered to be able to save server storage and increase hit ratio using the existing web cache infrastructure (click here to see how much storage can be saved). However, a rate adaptation algorithm still needs to be carefully designed for streaming scalable video.
Longhouse A longhouse or long house is a type of long, proportionately narrow, single-room building built by peoples in various parts of the world including Asia, Europe and North America. Many were built from timber and often represent the earliest form of permanent structure in many cultures. Types include the Neolithic long house of Europe, the stone Medieval Dartmoor longhouse which also housed livestock, and the various types of longhouses built by different cultures among the indigenous peoples of the Americas. Europe Four causes Four Causes refers to an influential principle in Aristotelian thought whereby causes of change or movement are categorized into four fundamental types of answer to the question "why?". Aristotle wrote that "we do not have knowledge of a thing until we have grasped its why, that is to say, its cause." While there are cases where identifying a cause is difficult, or in which causes might merge, Aristotle was convinced that his four causes provided an analytical scheme of general applicability.
Ancient skeletons discovered in Georgia threaten to overturn the theory of human evolution By David Derbyshire Updated: 12:26 GMT, 9 September 2009 For generations, scientists have believed Africa was the cradle of mankind. Now a stunning archaeological discovery suggests our primitive ancestors left Africa to explore the world around 800,000 years earlier than was previously thought before returning to their home continent. It was there - hundreds of thousands of years later - that they evolved into modern humans and embarked on a second mass migration, researchers say. Astonishing discovery: Archaeologists have unearthed six ancient skeletons dating back 1.8 million years in the hills of Georgia
Linear B Despite such a non-descriptive name, Linear B has proved to be the oldest surviving record of the Greek dialect known as Mycenaean, named after the great site of Mycenae where the legendary Agamemnon ruled. The script's usage spanned the time period between approximately 1500 BCE and 1200 BCE , and geographically covered the island of Crete, as well as the southern part of the Greek Mainland. The script was discovered by archeaologist Sir Arthur Evans in the early part of this century during excavations in Crete and the Greek mainland. However, its full decipherment did not occur until 1953, when Michael Ventris, an architect who actually liked linguistics and epigraphy more than architecture, and John Chadwick, who provided insight into the early history of the Greek language, worked out the phonetic values of Linear B signs and proved that its lexicon is that of an archaic Greek dialect. The following chart features the basic Linear B syllabary.
WebDAV Web Distributed Authoring and Versioning (WebDAV) is an extension of the Hypertext Transfer Protocol (HTTP) that allows clients to perform remote Web content authoring operations. A working group of the Internet Engineering Task Force (IETF) defined WebDAV in RFC 4918. The WebDAV working group concluded its work in March 2007, after the Internet Engineering Steering Group (IESG) accepted an incremental update to RFC 2518. Other extensions left unfinished at that time, such as the BIND method, have been finished by their individual authors, independent of the formal working group. Many modern operating systems provide built-in client-side support for WebDAV.
History of Chinese art Chinese art is visual art that, whether ancient or modern, originated in or is practiced in China or by Chinese artists. The Chinese art in the Republic of China (Taiwan) and that of overseas Chinese can also be considered part of Chinese art where it is based in or draws on Chinese heritage and Chinese culture. Early "stone age art" dates back to 10,000 BC, mostly consisting of simple pottery and sculptures. Telos (philosophy) In contrast to telos, techne is the rational method involved in producing an object or accomplishing a goal or objective; however, the two methods are not mutually exclusive in principle.
Top 10 Civilizations That Mysteriously Disappeared Throughout our history, most civilizations have either met a slow demise or were wiped out by natural disasters or invasion. But there are a few societies whose disappearance has scholars truly stumped: 10. The Olmec Log-structured merge-tree In computer science, the Log-Structured Merge-Tree (or LSM tree) is a data structure with performance characteristics that make it attractive for providing indexed access to files with high insert volume, such as transactional log data. LSM trees, like other search trees, maintain key-value pairs. LSM trees maintain data in two or more separate structures, each of which is optimized for its respective underlying storage medium; data is synchronized between the two structures efficiently, in batches.
Norse art Timeline for the Norse animal styles. Viking Age art or Norse art is a term for the art of Scandinavia and Viking settlements elsewhere, especially in the British Isles, during the Viking Age. Viking art has many elements in common with Celtic Art, Romanesque art and East-European (Eurasian). Historical Context Styles The Republic (Plato) Three interpretations of the Republic are presented; they are not exhaustive in their treatments of the work, but are examples of contemporary interpretation. In his A History of Western Philosophy (1945), Bertrand Russell identifies three parts to the Republic: Books I–V: the eutopia portraying the ideal community and the education of the Guardians, parting from attempting to define justice;Books VI–VII: define “philosopher”, since philosophers are the ideal rulers of such a community;Books VIII–X: discuss the pros and cons of various practical forms of government. Francis Cornford, Kurt Hildebrandt (de), and Eric Voegelin contributed to an establishment of sub-divisions marked with special formulae in Greek: Prologue
Atlantis Found: Giant Sphinxes, Pyramids In Bermuda Triangle Atlantis found in Bermuda Triangle Two scientists, Paul Weinzweig and Pauline Zalitzki, working off the coast of Cuba and using a robot submersible, have confirmed that a gigantic city exists at the bottom of the ocean. The site of the ancient city — that includes several sphinxes and at least four giant pyramids plus other structures — amazingly sits within the boundries of the fabled Bermuda Triangle. According to a report by Arclein of Terra Forming Terra, Cuban Subsea Pyramid Complex, the evidence points to the city being simultaneously inundated with rising waters and the land sinking into the sea. This correlates exactly with the Atlantis legend. The disaster may have occurred at the end of the last Ice Age.
