Oviraptoridae is a group of bird-like, herbivorous and omnivorous maniraptoran dinosaurs. Oviraptorids are characterized by their toothless, parrot-like beaks and, in some cases, elaborate crests . They were generally small, measuring between one and two metres long in most cases, though some possible oviraptorids were enormous.
The Oviraptoridae is further divided into the small, short-armed, and crestless subfamily Ingeniinae, and the larger, crested, long-armed Oviraptorinae. However, some phylogenetic studies have suggested that many traditional members of the Caenagnathidae were more closely related to the crested oviraptorids.
Oviraptor (/ ˈ oʊ v ɪ r æ p t ər /; lit. ' egg thief ') is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous period. The first remains were collected from the Djadokhta Formation of Mongolia in 1923 during a paleontological expedition led by Roy Chapman Andrews, and in the following year the genus and type species Oviraptor philoceratops were named by Henry ...
Many models of communication include the idea that a sender encodes a message and uses a channel to transmit it to a receiver. Noise may distort the message along the way. The receiver then decodes the message and gives some form of feedback. [1] Models of communication simplify or represent the process of communication.
Citipati embryo IGM 100/971. In 1993, a small fossilized oviraptorid embryo, labelled as specimen IGM 100/971, was discovered in a nest at the Ukhaa Tolgod locality of the highly fossiliferous Djadokhta Formation, Gobi Desert, during the Mongolian Academy of Sciences-American Museum of Natural History paleontological project.
However, that same year Rinchen Barsbold argued that Oviraptor belonged to a distinct family he named the Oviraptoridae [1] and he also formally named the Oviraptorosauria later in the same year. [2] Like their classification, the paleobiology of oviraptorosaurs has been subject to controversy and reinterpretation.
System information modelling (SIM) is the process of modelling complex connected systems. System information models are digital representations of connected systems, such as electrical instrumentation and control, power, and communication systems. The objects modelled in a SIM have a 1:1 relationship with the objects in the physical system.
Cybernetics is often understood within the context of systems science, systems theory, and systems thinking. [46] [47] Systems approaches influenced by cybernetics include critical systems thinking, which incorporates the viable system model; systemic design; and system dynamics, which is based on the concept of causal feedback loops.
