The Planning Domain Definition Language (PDDL) is an attempt to standardize Artificial Intelligence (AI) planning languages.
 It was first developed by Drew McDermott and his colleagues in 1998 (inspired by STRIPS and ADL among others) mainly to make the 1998/2000 International Planning Competition (IPC) possible, and then evolved with each competition. "
"The adoption of a common formalism for describing planning domains fosters far greater reuse of research and allows more direct comparison of systems and approaches, and therefore supports faster progress in the field.
 A common formalism is a compromise between expressive power (in which development is strongly driven by potential applications) and the progress of basic research (which encourages development from well-understood foundations).
 The role of a common formalism as a communication medium for exchange demands that it is provided with a clear semantics.""
Ruta Gedmintas (Lithuanian: "Rūta Gedmintas" ; ] ) is an English actress known for her work on television, primarily in "The Strain", "", "The Borgias", "The Tudors", and "Lip Service".

 Filming on a second series was confirmed in late 2010, with filming beginning on 30 May 2011.

The Internet is a relatively new communication medium in Indonesia, an archipelago that includes more than 17,000 islands.
 Several Internet access services are available in Indonesia, ranging from fiber optic, ADSL to mobile Internet.
 Telephone line-based service was among the first Internet access services in Indonesia with PT Telkom as the main player who controlled most fixed-line telephone networks.
A network packet is a formatted unit of data carried by a packet-switched network.
 When data is formatted into packets, and packet switching is employed, the bandwidth of the communication medium can be better shared among users than with circuit switching.
 Computer communications links that do not support packets, such as traditional point-to-point telecommunications links, simply transmit data as a bit stream.
In telecommunications, frequency-division multiplexing (FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency sub-bands, each of which is used to carry a separate signal.
 This allows a single transmission medium such as the radio spectrum, a cable or optical fiber to be shared by multiple independent signals.
 Another use is to carry separate serial bits or segments of a higher rate signal in parallel.
A Street Cat Named Bob is a 2016 British biographical drama film directed by Roger Spottiswoode and written by Tim John and Maria Nation.
 It is based on the book of same name by James Bowen.
 The film stars Luke Treadaway, Ruta Gedmintas, Joanne Froggatt, Anthony Head and Bob the Cat as himself.
 The film premiered in London on 3 November 2016, followed by a general release the next day.
Zebra Media Access Control (Z-MAC) is a network protocol for wireless sensor networks.
 It controls how a Media Access Control (MAC) accesses a common communication medium of a network.
Media Richness Theory, sometimes referred to as information richness theory or MRT, is a framework used to describe a communication medium's ability to reproduce the information sent over it.
 It was introduced by Richard L. Daft and Robert H. Lengel in 1986 as an extension of information processing theory.
 MRT is used to rank and evaluate the richness of certain communication media, such as phone calls, video conferencing, and email.
 For example, a phone call cannot reproduce visual social cues such as gestures which makes it a less rich communication media than video conferencing, which affords the transmission of gestures and body language.
 Based on contingency theory and information processing theory, MRT explains that richer, personal communication mediums are generally more effective for communicating of equivocal issues than leaner, less rich media.
Prowl is a 2010 American horror film directed by Patrik Syversen and written by Tim Tori and starring Courtney Hope, Ruta Gedmintas and Bruce Payne.
