Plainfield Central High School
Plainfield High School - Central Campus, or PHS-CC, is a four-year public high school in Plainfield, Illinois, a southwest suburb of Chicago, Illinois, in the United States. It is part of Plainfield Community Consolidated School District 202, which also includes three other high schools: Plainfield South High School, Plainfield North High School and Plainfield East High School. Campus history The original building was destroyed by one of the worst tornadoes in Illinois history. The Plainfield Tornado, which was rated an F5, struck the town on August 28, 1990, one day before classes were scheduled to begin. Three faculty and staff members lost their lives during this storm. Had school been in session, casualties could have been even more grave, as the tornado hit the school directly. In the middle of the 1992–1993 school year students moved into the new PHS building. At the time, it was one of the most technically advanced high schools in the state of Illinois, complete with i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Camera
A camera is an Optics, optical instrument that can capture an image. Most cameras can capture 2D images, with some more advanced models being able to capture 3D images. At a basic level, most cameras consist of sealed boxes (the camera body), with a small hole (the aperture) that allows light to pass through in order to capture an image on a light-sensitive surface (usually a Image sensor, digital sensor or photographic film). Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, and the aperture can be narrowed or widened. A Shutter (photography), shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. The still image camera is the main instrument in the art of photography. Captured images may be reproduced later as part of the process of photography, digital imaging, or photographic printing. Similar artistic fields in the moving-image camera dom ...

Wireless Network
A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Admin telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. Examples of wireless networks include cell phone networks, wireless local area networks (WLANs), wireless sensor networks, satellite communication networks, and terrestrial microwave networks. History Wireless networks The first professional wireless network was developed under the brand ALOHAnet in 1969 at the University of Hawaii and became operational in June 1971. The first commercial wireless network was the WaveLAN product family, developed by NCR i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-resolution
Image resolution is the detail an image holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly ''resolved''. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense. Instead of single lines, line pairs are often used, composed of a dark line and an adjacent light line; for example, a resolution of 10 lines per millimeter means 5 dark lines alternating with 5 light lines, or 5 line pairs per millimeter (5 LP/mm). Photographic lens and film resolution are most often quoted in line pairs per millimeter. Types The resolution of digital cameras can be described in many different ways. Pixel count The term ''resolution'' is ofte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shot Put
The shot put is a track and field event involving "putting" (throwing) a heavy spherical ball—the ''shot''—as far as possible. The shot put competition for men has been a part of the modern Olympics since their revival in 1896, and women's competition began in 1948. History Homer mentions competitions of rock throwing by soldiers during the Siege of Troy but there is no record of any dead weights being thrown in Greek competitions. The first evidence for stone- or weight-throwing events were in the Scottish Highlands, and date back to approximately the first century. In the 16th century King Henry VIII was noted for his prowess in court competitions of weight and hammer throwing. The first events resembling the modern shot put likely occurred in the Middle Ages when soldiers held competitions in which they hurled cannonballs. Shot put competitions were first recorded in early 19th century Scotland, and were a part of the British Amateur Championships beginning in 1866. ...

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brick
A brick is a type of block used to build walls, pavements and other elements in masonry construction. Properly, the term ''brick'' denotes a block composed of dried clay, but is now also used informally to denote other chemically cured construction blocks. Bricks can be joined using mortar, adhesives or by interlocking them. Bricks are usually produced at brickworks in numerous classes, types, materials, and sizes which vary with region and time period, and are produced in bulk quantities. ''Block'' is a similar term referring to a rectangular building unit composed of similar materials, but is usually larger than a brick. Lightweight bricks (also called lightweight blocks) are made from expanded clay aggregate. Fired bricks are one of the longest-lasting and strongest building materials, sometimes referred to as artificial stone, and have been used since circa 4000 BC. Air-dried bricks, also known as mud-bricks, have a history older than fired bricks, and have an additi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grandstand
A grandstand is a normally permanent structure for seating spectators. This includes both auto racing and horse racing. The grandstand is in essence like a single section of a stadium, but differs from a stadium in that it does not wrap all or most of the way around. Grandstands may have basic bench seating, but usually have individual chairs like a stadium. Grandstands are also usually covered with a roof, but are open on the front. They are often multi-tiered. Grandstands are found at places like Epsom Downs Racecourse and Atlanta Motor Speedway. They may also be found at fairgrounds, circuses, and outdoor arenas used for rodeos. In the United States, smaller stands are called bleachers, and are usually far more basic and typically single-tiered (hence the difference from a "grand stand"). Early baseball games were often staged at fairgrounds, and the term "grandstand" came along when standalone baseball parks began to be built. A covered bleacher may be call ...

Stadium
A stadium ( : stadiums or stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a tiered structure designed to allow spectators to stand or sit and view the event. Pausanias noted that for about half a century the only event at the ancient Greek Olympic festival was the race that comprised one length of the stadion at Olympia, where the word "stadium" originated. Most of the stadiums with a capacity of at least 10,000 are used for association football. Other popular stadium sports include gridiron football, baseball, cricket, the various codes of rugby, field lacrosse, bandy, and bullfighting. Many large sports venues are also used for concerts. Etymology "Stadium" is the Latin form of the Greek word " stadion" (''στάδιον''), a measure of length equalling the length of 600 human feet. As feet are of variable length the exact length of a stadion depends on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skyway
A skyway, skybridge, skywalk, or sky walkway is an elevated type of pedway connecting two or more buildings in an urban area, or connecting elevated points within mountainous recreational zones. Urban skyways very often take the form of enclosed or covered footbridges that protect pedestrians from the weather. Open-top modern skyways in mountains now often have glass bottoms. Sometimes enclosed urban skywalks are made almost totally from glass, including ceilings, walls and floors. Also, some urban skyways function strictly as linear parks designed for walking. In North America skyways are usually owned by businesses, and are therefore not public spaces (compare with sidewalk). However, in Asia, such as Bangkok's and Hong Kong's skywalks, they are built and owned separately by the city government, connecting between privately run rail stations or other transport with their own footbridges, and run many kilometers. Skyways usually connect on the first few floors above the ground ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
