SILK

SILK is an audio compression format and audio codec developed by Skype Limited. It was developed for use in Skype, as a replacement for the SVOPC codec. Since licensing out, it has also been used by others. It has been extended to the Internet standard Opus codec.

Details

Skype Limited announced that SILK can use a sampling frequency of 8, 12, 16 or 24 kHz and a bit rate from 6 to 40 kbit/s. It can also use a low algorithmic delay of 25 ms (20 ms frame size + 5 ms look-ahead). The reference implementation is written in the C programming language. The codec technology is based on linear predictive coding (LPC). The SILK binary SDK is available.

License

The SILK codec is patented and licensed separately from the SILK SDK. The codec is open-source, freeware, available royalty free with restrictions on use and distribution. The SDK was initially available only by application by giving details of name, address, phone, and description of how SILK will be used.As of 2012 (version 1.0.9) the SDK can by downloaded without application, but the licence restricts the use to internal evaluation and testing purposes only, excluding software distribution or use in any commercial product or service.

Silk (comics)

Silk (Cindy Moon) is a fictional superheroine appearing in American comic books published by Marvel Comics.

Publication history

The character first appeared in The Amazing Spider-Man vol. 3 #1 (April 2014) as a faceless cameo and was created by Dan Slott and Humberto Ramos. She made several other faceless appearances throughout the volume's first story arc, before making her full debut in The Amazing Spider-Man vol. 3 #4 (July 2014), as part of a tie-in to the Original Sin storyline. An ongoing title featuring Silk started publishing in February 2015, with scripts by Supernatural writer Robbie Thompson and art by Stacey Lee.Silk volume 1 will come to an end with a "Last Days" story arc that ties into Secret Wars, after which Silk will star in a second volume of her solo series.

Fictional character biography

Thirteen years ago during a demonstration on the use of radioactive rays at a science exhibit, a spider was accidentally exposed to the radiation and absorbed large amounts of it. In its dying moments, the arachnid bit the nearest living thing to it, Peter Parker. As a result, the young teenager would gain amazing powers and become Spider-Man. However, this was not the end. As mere moments after biting Parker, the spider bites another young student by the name of Cindy Moon. Soon after, Cindy’s abilities manifested but she was unable to control them. Some time later, Ezekiel would approach the Moon family to offer his help and guide Cindy in controlling her newfound abilities. After six years since getting bit and training to use her powers, Cindy is locked up inside a facility by Ezekiel to protect her and the other “spiders” from Morlun and his family called the Inheritors.

Silk (group)

Silk is an American R&B group, formed in 1989 in Atlanta, Georgia. They are best known for their 1993 hit single, "Freak Me", which reached number-one on the US Billboard Hot 100.

Career

Silk is best known for their hit singles, "Freak Me", and "Happy Days" from their debut album, Lose Control. Another hit from Lose Control, "Girl U For Me", helped the album reach double platinum status. They later had success with singles such as "I Can Go Deep", "Hooked on You", "Don't Rush", "If You" (released February 23, 1999) "Meeting in My Bedroom", and "We're Calling You."

Silk was discovered by the musician Keith Sweat. The group was originally a quintet made up of Timothy "Timzo" Cameron, Jimmy Gates, Jr., Johnathen "John John" Rasboro, Tyga Graham & Albert Allen. Gary "Big G" Glenn & Gary "lil G" Jenkins joined shortly after the departures of Graham & Allen. In 2002, Silk left the label and took a hiatus. That same year, Jenkins went on to pursue other interests and made his stage debut in 2002 as 'AJ' in the Tyler Perry play Madea's Family Reunion. He resurfaced musically in 2007 with his solo debut, The Other Side. In addition to being discovered by Keith Sweat, Silk and Sweat both appeared in the group, Black Men United on the track, "U Will Know" for the movie, Jason's Lyric the film's soundtrack.

International Ultramarine Corps

The International Ultramarine Corps, formerly the Ultramarine Corps, is a fictional team of superheroes published by DC Comics. They first appeared in DC One Million #2 (November 1998), and were created by Grant Morrison and Howard Porter.

History

The Corps was created by the U.S. as a government-sponsored group of superhumans to rival the more independent Justice League. Led by General Wade Eiling, the original members of the team were Flow, 4-D, Pulse 8 and Warmaker One. During a fight with the JLA, the UMC realised that Eiling was dangerously insane and that they were on the wrong side; they then sided with the League against their leader.

Having developed a mistrust of governments, the Corps subsequently declared themselves independent of any and all nations and built a free-floating city in which to dwell, which they named Superbia and set in the air above the ruins of Montevideo. They put out a call to other disaffected superheroes to join them in their city, and received a number of responses from around the globe, although the total population and demographics of Superbia are unknown.

Traffic flow (computer networking)

In packet switching networks, traffic flow, packet flow or network flow is a sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain. RFC 2722 defines traffic flow as "an artificial logical equivalent to a call or connection."RFC 3697 defines traffic flow as "a sequence of packets sent from a particular source to a particular unicast, anycast, or multicast destination that the source desires to label as a flow. A flow could consist of all packets in a specific transport connection or a media stream. However, a flow is not necessarily 1:1 mapped to a transport connection." Flow is also defined in RFC 3917 as "a set of IP packets passing an observation point in the network during a certain time interval."

Conceptual description

A flow can be uniquely identified by the following parameters within a certain time period:

Flow (mathematics)

In mathematics, a flow formalizes the idea of the motion of particles in a fluid. Flows are ubiquitous in science, including engineering and physics. The notion of flow is basic to the study of ordinary differential equations. Informally, a flow may be viewed as a continuous motion of points over time. More formally, a flow is a group action of the real numbers on a set.

The idea of a vector flow, that is, the flow determined by a vector field, occurs in the areas of differential topology, Riemannian geometry and Lie groups. Specific examples of vector flows include the geodesic flow, the Hamiltonian flow, the Ricci flow, the mean curvature flow, and the Anosov flow. Flows may also be defined for systems of random variables and stochastic processes, and occur in the study of ergodic dynamical systems. The most celebrated of these is perhaps the Bernoulli flow.

Formal definition

A flow on a set X is a group action of the additive group of real numbers on X. More explicitly, a flow is a mapping
