Unmanned space missions

100 Unmanned space missions are those using remote-controlled spaceship. The first such assignment was the Sputnik I assignment, launched October 4, 1957. Some missions are more appropriate for unmanned missions rather than manned space missions, due to minor cost and lower risk factors. Since the early 1970s, most unmanned space missions have been based on space probe with built-in assignment computers, and as such may be classified as entrenched systems.

Most American unmanned missions have been synchronized by the Jet Propulsion Laboratory, and European missions by the European Space Operations Centre, part of ESA. ESA has conducted comparatively few space examination missions. ESA has, however, launched a variety of spacecraft to carry out astronomy, and is a coworker with NASA on the Hubble Space Telescope. There have been a great number of very winning Russian space missions. There were also a small number of Japanese and Chinese missions.

Clock

A clock is an instrument for measuring time.Those used for technical purposes, of extremely high accuracy, are sometimes called chronometers. A portable clock is called a watch. The clock in its most common modern form displays the hours, minutes, and sometimes seconds that pass over a twelve or twenty-four-hour period.
The world's first self-striking clock was said to be invented by Chang Yeong-Sil, a chief enginner of Korea, in Korea during the Joseon Dynasty. It was called Chagyongru, which means "self-striking clock" in Korean
The development of electronics in the twentieth century led to clocks with no clockwork parts at all. Time in these cases is measured in several ways, such as by the behaviour of quartz crystals, or the decay of radioactive elements. Even mechanical clocks contain since come to be largely powered by batteries, removing the need for winding.

Peach

The peach (Prunus persica) is a tree that bears a juicy fruit of the same name. It has a single large seed enclosed in hard wood (called the "pit" or "stone"), yellow or whitish flesh, a delicate aroma, and a velvety skin. Peaches, along with cherries, plums and apricots, are stone fruits (drupes). Cultivated peaches are separated into freestone and clingstone varieties, depending on whether the flesh sticks to the pit; both kinds can be any color. Peaches with white flesh characteristically are very sweet with little acid flavor, while yellow-fleshed peaches classically have an acidic tang coupled with sweetness. Both colors often have some red on their skin. Low-acid white-fleshed peaches are the most popular kinds in China, Japan, and neighboring Asian countries, while Europeans and North Americans have historically favored the acidic, yellow-fleshed kinds.

Kashmir

Kashmir is known as heaven on the earth. In the seventeenth century the Mughal emperor Jahangir set his eyes on the valley of Kashmir. He said that if paradise is anywhere on the earth, it is here, while living in a house boat on the mesmerizing Dal Lake. The pleasure of the Mughal gardens makes every minute one spends in Kashmir a joy to the soul. In Jammu and Kashmir the most significant tourist places are Kashmir, Srinagar, Mughal gardens, Gulmarg, Pahalgam-the valley of shepherds, Jammu, Ladakh.
Because of the quite tolerable climate on the higher planes of Jammu and Kashmir, and also because of its scenic beauty and bodies of water, Jammu and Kashmir are a tourist attraction. Until a few decades ago, "Going to Kashmir" was synonymous in India with going on a honeymoon, or for a tour to a cold place during hot summers.
Some areas need a special permit for non-indians to visit.

Manga

Manga is the Japanese word for comics and print cartoons. Outside of Japan, it generally refers specifically to comics initially published in Japan. As of 2007, manga represents a multi-billion dollar global market.Manga developed from a mixture of ukiyo-e and foreign styles of drawing, and took its current form shortly after World War II. It comes primarily in black and white, except for the covers and sometimes the first few pages; in some Animanga (Anime printed in Manga style) all the pages are colored.
Popular manga are frequently adapted into anime (Japanese for animation) once a market interest has been established (Manga is sometimes mistakenly called "anime" by those not familiar with the term). Adapted stories are often modified to appeal to a more mainstream market. Although not as general, original anime is sometimes adapted into manga (such as the Gundam franchise, Neon Genesis Evangelion, Cowboy Bebop and Tenchi Muyo).

Deafness

The word deaf is used in a different way in different contexts, and there is some controversy over its meaning and implications. In scientific and medical terms, deafness normally refers to a physical condition characterized by lack of sensitivity to sound. Notated as deaf with a lowercase d, this refers to the audiological experience of someone who is partly or wholly lacking hearing In legal terms, deafness is defined by degree of hearing loss. These degrees include profound or total deafness (90 dB - 120 dB or more of hearing loss), severe (60 dB - 90 dB), moderate (30 dB - 60 dB), and mild deafness(10 dB - 30 dB of hearing loss). Both severe and moderate deafness can be referred to as partial deafness or as hard of hearing, while mild deafness is usually called hard of hearing.
Within the Deaf community, the term "Deaf" is often capitalized when written, and it refers to a tight-knit cultural group of people whose primary language is signed, and who practice social & cultural norms which are different from those of the surrounding hearing community. This community does not mechanically include all those who are clinically or legally deaf, nor does it exclude every hearing person. According to Baker & Padden, it includes any person or persons who "identifies him/herself as a member of the Deaf community, and other members accept that person as a part of the community"

Traditional animation

This animation called cel animation, the frames of a traditionally animated movie are hand-drawn. The drawings are traced or copied onto transparent acetate sheets called cels, which are then located over a painted background and photographed one by one on a rostrum camera. Nowadays, the use of cels (and cameras) is mostly obsolete, since the drawings are scanned into computers, and digitally transferred directly to 35 mm film. The "look" of traditional cel animation is still preserved, and the character animator's work has remained essentially the same over the past 70 years. Because of the digital influence over modern cel
animation, it is also known as tradigital animation.Examples: The Lion King, Spirited Away, Les Triplettes de Belleville
Full animation
The most common style in animation, known for its realistic and often very detailed art.
Examples: All Disney feature length animated films, The Secret of NIMH, The Iron Giant
Limited animation
A cheaper process of creating animated cartoons that does not follow a "realistic" approach.
Examples: The Flintstones, Yellow Submarine
Rubber hose
The characters are usually cartoony, and the animators have a lot of artistic freedom as rubber hose animations don't have to follow the laws of physics and anatomy in the same degree as the other main styles in animation.
Examples: Early Mickey Mouse cartoons, Ren and Stimpy, Popeye
Rotoscoping
A technique where animators trace live action movement, frame by frame, for use in animated films.
Examples: Gulliver's Travels, American Pop
