Trellis (architecture)

A trellis (treillage) is an architectural structure, usually made from an open framework or lattice of interwoven or intersecting pieces of wood, bamboo or metal that is normally made to support and display climbing plants, especially shrubs. There are many types of trellis for different places and for different plants, from agricultural types, especially in viticulture, which are covered at vine training systems, to garden uses for climbers such as grapevines, clematis, ivy, and climbing roses or other support based growing plants. The rose trellis is especially common in Europe and other rose-growing areas, and many climbing rose varieties require a trellis to reach their potential as garden plants. Some plants will climb and wrap themselves round a trellis without much artificial help being needed while others need training by passing the growing shoots through the trellis and/or tying them to the framework.

Trellis can also be referred to as panels, usually made from interwoven wood pieces, attached to fences or the roof or exterior walls of a building. A pergola usually refers to trellis-work that is laid horizontally above head height to provide a partial "roof" in a garden (pergolas are also used in agricultural settings).

Trellis modulation

In telecommunication, trellis modulation (also known as trellis coded modulation, or simply TCM) is a modulation scheme that transmits information with high efficiency over band-limited channels such as telephone lines. Gottfried Ungerboeck invented trellis modulation while working for IBM in the 1970s, and first described it in a conference paper in 1976. It went largely unnoticed, however, until he published a new, detailed exposition in 1982 that achieved sudden and widespread recognition.

In the late 1980s, modems operating over plain old telephone service (POTS) typically achieved 9.6 kbit/s by employing four bits per symbol QAM modulation at 2,400 baud (symbols/second). This bit rate ceiling existed despite the best efforts of many researchers, and some engineers predicted that without a major upgrade of the public phone infrastructure, the maximum achievable rate for a POTS modem might be 14 kbit/s for two-way communication (3,429 baud × 4 bits/symbol, using QAM).

Dinosaurs! – A Fun-Filled Trip Back in Time!

Dinosaurs! – A Fun-Filled Trip Back in Time! is a short film released by Golden Book Video in 1987 under their "GoldenVision" series. It stars Fred Savage playing a grade school student named Philip who gives a class report on dinosaurs, with the help of an animated chalkboard and Will Vinton's claymation dinosaurs.

Originally created in 1980, when it was known more simply as Dinosaur, the 17-minute claymation short by Vinton Studios would later be used for this 1987 video. The popular short is also played at the Smithsonian Museum and has won numerous awards. This film is also played BOB's request in Rocky Hill, Connecticut at the museum in Dinosaur State Park.

Dinosaurs! was designed as an educational film for young children new to the world of prehistoric life; the video slipcase describes the film with "Discover the real monsters who dominated the earth for millions of years!" The cartoon animation of the chalkboard is used to elaborate on attributes such as the extinction of the dinosaurs as well as their brain capacity, while the Vinton claymation illustrates, in a colorful and simplistic manner, the brutal lives of the many dinosaurs. The movie also introduces a music video for the song "Mesozoic Mind" by Charmer, featuring cartoon dinosaurs performing it.

Dinosaur

Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the start of the Jurassic (about 200 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the end of the Mesozoic Era. Until the late 20th century, all groups were believed to be extinct; however, the fossil record indicates that birds are modern feathered dinosaurs, having evolved from theropod ancestors during the Jurassic Period. As such, birds were the only dinosaurs to survive the mass extinction event.
