Construction



Building automation


Building automation is a programmed, computerized, intelligent network of electronic devices that monitor and control the mechanical and lighting systems in a building. The intent is to create an intelligent building and reduce energy and maintenance costs.
Infrastructure

Controller
The controller is normally one or more application specific controllers, often with less complex programming. These controllers come in a wide range of sizes and capabilities to control devices that are common in buildings. Usually the primary and secondary buses are chosen based on what the controllers provide.
Most PLCs provide general purpose feedback loops, as well as digital circuits.

Occupancy sensors
Occupancy is usually based on time of day schedules. Override is possible through different means. Some buildings can sense occupancy in their internal spaces by an override switch or sensor.

Lighting
Lighting can be turned on and off with a building automation system based on time of day, or the occupancy sensors and timers. One typical example is to turn the lights in a space on for a half hour since the last motion was sensed. A photocell placed outside a building can sense darkness, and the time of day, and modulate lights in outer offices and the parking lot.

Air handlers
Most air handlers mix return and outside air so less temperature change is needed. This can save money by using less chilled or heated water (not all AHUs use chilled/hot water circuits). Some external air is needed to keep the building's air healthy.
Analog or digital temperature sensors may be placed in the space or room, the return and supply air ducts, and sometimes the external air. Actuators are placed on the hot and chilled water valves, the outside air and return air dampers. The supply fan (and return if applicable) is started and stopped based on either time of day, temperatures, building pressures or a combination.

Constant Volume Air-Handling Units

The less efficient type of air-handler is a "Constant Volume Air Handling Unit," or CAV. The fans in CAVs do not have variable-speed controls. Instead, CAVs open and close dampers and water-supply valves to maintain temperatures in the building's spaces. They heat or cool the spaces by opening or closing chilled or hot water valves that feed their internal heat exchangers. Generally one CAV serves several spaces, but large buildings may have many CAVs.

Variable Volume Air-Handling Units
A more efficient unit is a "Variable air volume (VAV) Air-Handling Unit," or VAV. VAVs supply pressurized air to VAV boxes, usually one box per room or area. A VAV air handler can change the pressure to the VAV boxes by changing the speed of a fan or blower with a variable frequency drive or (less efficiently) by moving inlet guide vanes to a fixed-speed fan. The amount of air is determined by the needs of the spaces served by the VAV boxes.
Each VAV box supply air to a small space, like an office. Each box has a damper that is opened or closed based on how much heating or cooling is required in its space. The more boxes are open, the more air is required, and a greater amount of air is supplied by the VAV air-handling unit.
Some VAV boxes also have hot water valves and an internal heat exchanger. The valves for hot and cold water are opened or closed based on the heat demand for the spaces it is supplying. These heated VAV boxes are sometimes used on the perimeter only and the interior zones are cooling only.
A minimum and maximum CFM must be set on VAV boxes to assure adaquate ventilation and proper air balance.

VAV Hybrid Systems
Another variation is a hybrid between VAV and CAV systems. In this system, the interior zones operate as in a VAV system. The outer zones differ in that the heating is supplied by a heating fan in a central location usually with a heating coil fed by the building boiler. The heated air is ducted to the exterior dual duct mixing boxes and dampers controlled by the zone thermostat calling for either cooled or heated air as needed.

Central plant
A central plant is needed to supply the air-handling units with water. It may supply a chilled water system, hot water system and a condenser water system, as well as transformers and auxiliary power unit for emergency power. If well managed, these can often help each other. For example, some plants generate electric power at periods with peak demand, using a gas turbine, and then use the turbine's hot exhaust to heat water or power an absorptive chiller.

Chilled water system
Chilled water is often used to cool a building's air and equipment. The chilled water system will have chiller(s) and pumps. Analog temperature sensors measure the chilled water supply and return lines. The chiller(s) are sequenced on and off to chill the chilled water supply.

Condenser water system
Cooling tower(s) and pumps are used to supply cool condenser water to the chillers. The condenser water supply to the chillers has to be constant so, speed drives are commonly used on the cooling tower fans to control temperature. Proper cooling tower temperature assures the proper refrigerant head pressure in the chiller. The cooling tower set point used depends upon the refrigerant being used. Analog temperature sensors measure the condenser water supply and return lines.

Hot water system
The hot water system supplies heat to the building's air-handling units or VAV boxes. The hot water system will have a boiler(s) and pumps. Analog temperature sensors are placed in the hot water supply and return lines. Some type of mixing valve is usually used to control the heating water loop temperature. The boiler(s) and pumps are sequenced on and off to maintain supply.

Alarms and security
Many building automation systems have alarm capabilities. If an alarm is detected, it can be programmed to notify someone. Notification can be through a computer, pager, cellular phone, or audible alarm.
Common temperature alarms are Space, Supply Air, Chilled Water Supply and Hot Water Supply.
Differential pressure switches can be placed on the filter to determine if it is dirty.
Status alarms are common. If a mechanical device like a pump is requested to start, and the status input indicates it is off. This can indicate a mechanical failure.
Some valve actuators have end switches to indicate if the valve has opened or not.
Carbon monoxide and carbon dioxide sensors can be used to alarm if levels are too high.
Refrigerant sensors can be used to indicate a possible refrigerant leak.
Amperage sensors can be used to detect low amperage conditions caused by slipping fan belts, or clogging strainers at pumps.
At sites with several buildings, momentary power failures can cause hundreds or thousands of alarms from equipment that has shut down. Some sites are programmed so that critical alarms are automatically re-sent at varying intervals. For example, a repeating critical alarm (of a uninterruptible power supply in 'by pass') might resound at 10 minutes, 30 minutes, and every 2 to 4 hours there after until the alarms are resolved.
Security systems can be interlocked to a building automation system. If occupancy sensors are present, they can also be used as burglar alarms.
Fire and smoke alarm systems can be hard-wired to override building automation. For example: if the smoke alarm is activated, all the outside air dampers close to prevent air coming into the building, and an exhaust system can isolate the alarmed area and activate an exhaust fan to move smoke out of the area. Life safety applications are normally hard-wired to a mechanical device to override building automation control.

GLOBAL WARMING: Reading activities


A CLOSER LOOK TO GLOBAL WARMING

Global warming refers to the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in greenhouse gas concentrations via the greenhouse effect”. Natural phenomena such as solar radiation combined with active volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward. These basic conclusions have been endorsed by at least 30 scientific societies and academies of science. While individual scientists have voiced disagreement with some of the main conclusions of the IPCC, the overwhelming majority of scientists working on climate change are in agreement with them.

Increasing global temperatures will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, glacier retreat, species extinctions, and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the amount of warming expected in the future, and how warming and related changes will vary from region to region around the globe. There is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences. Most national governments have signed and ratified the Kyoto Protocol, aimed at reducing greenhouse gas emissions.

Flying Objects



The helicopter

A helicopter is an aircraft which is lifted and propelled by one or more horizontal rotors, each rotor consisting of two or more rotor blades. Helicopters are classified as rotorcraft or rotary-wing aircraft to distinguish them from fixed-wing aircraft because the helicopter derives its source of lift from the rotor blades rotating around a mast. The word 'helicopter' is adapted from the French hélicoptère, coined by Gustave de Ponton d'Amecourt in 1861.

As an aircraft, the primary advantages of the helicopter are due to the rotor blades that revolve through the air, providing lift without requiring the aircraft to move forward the way an airplane does. This creates the ability for the helicopter to take off and land vertically without the need for runways. For this reason, helicopters are often used to operate in congested or isolated areas where airplanes are generally not able to take off or land. The lift from the rotor also allows the helicopter to hover in one area for extended periods of time, and to do so more efficiently than other forms of vertical take-off and landing aircraft, making it useful in accomplishing tasks that airplanes are not able to perform.

Although helicopters were developed and built during the first half century of flight, some even reaching limited production; it wasn't until 1942 that a helicopter designed by Igor Sikorsky became the first helicopter to enter full-scale production, totaling over 400 copies. Even though most previous designs utilized more than one main rotor, it was the single main rotor with antitorque tail rotor configuration of this design that would come to be recognized worldwide as the helicopter.

Vocabulary

- Aircraft: vehicle which is able to fly through the air (or through any other atmosphere).

- Lifted: mechanical force generated by solid objects as they move through a fluid.

- Rotors: the rotating armature of a motor or generator.

- Rotorcraft: category of heavier-than-air flying machines that use lift generated by wings that revolve around a mast called rotor blades.

- Fixed- wing aircraft: heavier-than-air craft where movement of the wings in relation to the aircraft is not used to generate lift.

- To take off: depart from the ground.

- To land: arrive to ground.

- To hover: hang in the air; fly or be suspended above.

GLOBAL WARMING: Text



Our text deals with one of the most important issues regarding Global Warming, the Ice melting in the Arctic.



Global warming threatens Arctic

The Arctic ice cap is melting so rapidly it may completely disappear by the end of the century, US scientists have warned. Experts at America’s National Snow and Ice Data Centre* (NSIDC) have reported that recent satellite images revealed the volume of sea ice was the lowest figure on record. The polar ice pack has shrunk by 30 percent since 1978. An area five times larger than the UK has vanished and the Arctic’s disappearing act is quickening. This year saw the warmest Arctic summer in 400 years. Dr. Mark Serreze from the NSIDC said: “The year 2005 puts an exclamation point on the pattern of Arctic warming.” He attributes the worrying trend of melting ice caps to global warming.
The NSIDC’s leader Dr. Ted Scambos said the Arctic Circle is receding at such a rate that it is now close to a “tipping point” from which it may never recover. He said the Arctic is caught in a vicious circle, which, within a century, may lead to high temperatures not seen for a million years. Less sea ice means the planet cannot reflect the suns rays and cool itself. Warmer seas and oceans absorb more of the sun’s heat, which in turn melts more ice. The loss of sea ice is a self-perpetuating recipe for climate disaster. Current shrinkage is estimated at eight percent per decade, which means there may be no ice at all during the Arctic summer of 2060. Dr. Scambos issued a dire warning that it is “pretty certain a long-term decline is underway”.

Videogame’s Timeline

The First Video Game: Tennis for Two
Jan 1, 1958
Physicist Willy Higinbotham invents the first "video game" at the Brookhaven National Laboratory in Upton, New York. His game, a table tennis-like game, was played on an oscilloscope. It is used to entertain visitors at the lab's annual open house.

Spacewar (PDP-1) (VIDEO)
Jan 1, 1961
Steve Russell, a student at the Massachusetts Institute of Technology (MIT), creates Spacewar, the first interactive computer game. It runs on a Digital PDP-1 mainframe computer, and the graphics are made up of ASCII text characters. It quickly spreads to universities and research facilities around the country.
Spacewar! is one of the earliest known digital computer games.
Steve "Slug" Russell, Martin "Shag" Graetz and Wayne Wiitanen of the fictitious "Hingham Institute" conceived of the game in 1961, with the intent of implementing it on a DEC PDP-1 at the Massachusetts Institute of Technology. After Alan Kotok obtained some sine and cosine routines from DEC, Russell began coding, and by February 1962 had produced his first version. It took approximately 200 hours of work to create the initial version. Additional features were developed by Dan Edwards, Peter Samson, and Graetz

The Galaxy Game is the earliest known coin-operated computer or video game. It was installed at the Tresidder Union at Stanford University in September, 1971, two months before the release of Computer Space, the first mass-produced such game.[1] Only one unit was ever built, though the game later included several consoles allowing users to play against each other.The game was programmed by Bill Pitts and Hugh Tuck. Like Computer Space, it was a version of the existing Spacewar!, which had previously been played on the PDP-1. The coin-operated game console incorporated a Digital PDP-11/20 with vector displays. The hardware cost around $20,000, and a game cost 10 cents or three games for 25 cents. In June 1972 the hardware was improved to allow the processor to power four to eight consoles. The game remained popular on campus, with wait times for players as much as one hour, until it was removed in May 1979.
The unit was restored in 1997 and now resides in the Computer History Museum in Mountain View, California.
Computer Space is a video arcade game released in November 1971 by Nutting Associates. Created by Nolan Bushnell and Ted Dabney, who would both later found Atari, it is generally accepted that it was the world's first commercially sold coin-operated video game — and indeed, the first commercially sold video game of any kind, predating the Magnavox Odyssey by six months, and Atari's Pong by one year. Though not commercially sold, the coin operated minicomputer driven Galaxy Game preceded it by two months, located solely at Stanford University.


Video Game Consoles (1970-1976)
Magnavox Odyssey
Released in 1972
The Magnavox Odyssey is the first home video game console, predating the Atari PONG home consoles by three years. The Odyssey was designed by Ralph Baer, who had a working prototype finished by 1968. This prototype is affectionately known as the "Brown Box" to classic video game hobbyists. Unlike most video game consoles, the Odyssey is analog rather than digital, which makes its invention all the more amazing in spite of its rather crude graphics and controller responsiveness. Also, unlike any conventional console today, this system was powered by batteries. The Odyssey and its variants also lack sound capability (hence a silent console), which was not uncommon in early PONG systems of that era.
The Odyssey was released in May 1972. While it did not perform badly, it did not take long before it succumbed to poor marketing by Magnavox retail chains. One of their mistakes was misleading consumers into believing that the Odyssey would work only on Magnavox televisions. It did, however, prove that consoles for the home could be designed.

Atari PONG
Released in 1975
In 1973, after the success of the original PONG coin-op, an Atari engineer by the name of Harold Lee came up with the idea of a home PONG unit. Since the PONG coin-op that Alan Alcorn designed was nothing more than the game board connected to an actual television set, he thought it would be possible to scale it down a bit and modify it for use at home. This would be a new direction for the fledgling Atari consumer electronics. If they could pull it off, they would be one of the pioneers of using high tech custom integrated circuits in the consumer industry.
In 1975 it was decided Sears would sell PONG under it's own specially created Tele-Games label, and production was initially projected at 50,000 units. This was soon raised to 150,000 for the 1975 Christmass season. Atari agreed to give Sears exclusive rights for the following year, and would continue to make custom Tele-Games versions for any future consoles. This was the beginning of a long relationship between Atari and Sears, which would continue even after Nolan Bushnell sold Atari to Warner.

Magnavox Odyssey 100
Released in 1975
The Odyssey 100 was an analog system which used four Texas Instruments chips. It did not use cartridges and played two games: TENNIS and HOCKEY. A simple switch selected the games, and the system was either powered by six batteries, or by an AC adaptor (such power supplies were widely used by other systems).
The Odyssey 100 was very basic and didn't have the common features of the million-seller PONG systems of the next years. The knobs were fixed: there were no detachable controllers yet. There was no digital on-screen scoring: the players marked their score using two little plastic cursors on the system. The serve couldn't be changed: it was automatic. This could seem strange compared to the first Atari PONG systems which already had digital on-screen scoring. In fact, this was just a question of technology. On-screen scoring would have required additional components, which would have increased the cost of the system. Nevertheless, on-screen scoring was added in later systems although the first attempts used archaic graphics. The first Magnavox system to offer digital on-screen was the Odyssey 300 in 1976.

Magnavox Odyssey 200
Released in 1975
Still in 1975, Magnavox released an improved version of the Odyssey 100: the Odyssey 200. It was same as the Odyssey 100 but with two additional chips from Texas Instruments, which added a third game called SMASH and some on-screen scoring. The Odyssey 200 could be played by two or four players (first system to offer this feature), and displayed very basic on-screen scoring using small rectangles (it still had the two plastic cursors to record the scores). Each time a player marked a point, his white rectangle would shift on the right. The winner was obviously the first whose rectangle would reach the rightmost position on the screen. Although the scores were not yet digital, the Odyssey 200 remained more advanced than the first home version of Atari PONG because it played three different games for two or four players.
1975 marked the beginning of a long history. Both Atari and Magnavox released their systems, and more advanced ones were to come.

Atari Super PONG
Released in 1976
Atari's sales of the Home PONG console were phenomenal to put it mildly. Atari would continue to cash in of the PONG franchise by releasing yet another home version of one of its arcade game assets. This time it would be Super PONG. Now home players could select for 4 different variations of PONG games to delight and entertain them for countless hours.
Meanwhile numerous knock-off PONG-type consoles were hitting the market. However, because of Atari's now well known presence in the coin-op market, its name recognition helped it stand out. Also Atari's unusual Pedestal design helped Atari stand out in the Sears Retail Stores as well as other stores who were now carrying Atari products.
When compared to the plethora of bland and boxy "Me-Too" consoles by so many other companies, the Atari PONG line of consoles simply stood out. Atari's consoles had eye catching rainbow colors and a deep and ear catching PONG sound from their built in speaker. Most other consoles were still far behind playing catch up with Black & White displays, flimsy controllers and some even without sound.

Pac-man
Jan, 1980
The Japanese company, Namco, along with America's Midway, bring the game Puck-Man to the US. Fearing that the American public will be tempted to alter the game's name to something more offensive, distributors re-name it Pac-Man prior to its debut. This hugely pouplar game is the first to have an animated main character with its own name. 300,000 units of Pac-Man are released worldwide by Namco.

Nintendo Famicom released in Japan
Jan 3, 1983
Nintendo introduces the Famicom in Japan—later known as the Nintendo Entertainment System (NES) in the U.S. Since Atari controls such a large percentage of the market, they do not plan to market the product in the U.S. Instead the company offers Atari the rights to distribute the product in the U.S. These plans fall through and Americans do not see Nintendo until 1985.

Vocabulary
  • Simulation Games
While arguably most games are a simulation of something, simulation games, or "sims" take it a step further, recreating a particular situation in more exacting detail. Flight sims, for example, give the player full control of the plane, down to every switch and gauge. Other types of sims replicate driving a race car, coaching a sports team, running a city, or even dating

  • Packet Loss
Brief interruptions in gameplay caused by a poor connection to a server. This appears as a slight delay in the action, or if the connection is very unstable, a stuttering effect. Synonym: lag.

  • XP (Experience Points)
In roleplaying games, the player gains these by defeating enemies or accomplishing key goals. After a certain number of points, the player gains new abilities and grows stronger, a process known as "leveling up." Gamers play in many different ways. Here are some terms you might hear when someone describes another gamer's style
Server
A computer or device on a network that manages network resources. For example, when you want to join a game on Xbox Live, you choose from a list of servers running the game

Weight Loss Computer Game: Exercise To Win

ScienceDaily (Sep. 21, 2007)Finding a way to motivate the billion people in the world who are overweight to lose excess pounds can be an overwhelming task, but a University of Houston professor is meeting that weighty challenge with a challenge of his own.

Ioannis Pavlidis, a UH computer science professor, and research assistants Yuichi Fujiki and Kostas Kazakos, have developed a computer game that translates physical activity into video games, such as races and logic puzzles. Dubbed Non-Exercise Activity Thermogenesis (NEAT-o) games, they can be played on any hand-held personal digital assistant (PDA) with users wearing a lightweight, wearable sensor that detects movement like running, walking, bending over or even foot tapping.

That data is then transmitted to the PDA via a wireless connection, and the player can see his or her game avatar move in real-time to their movements. For example, in the race game, the player’s physical activity propels the avatar around the track – the more active the player is, the faster and farther the avatar goes.

“When you see the avatar move when you move, you really become connected to the game,” Pavlidis said.

Capitalizing on the buddy system for working out, users can link to other gamers by cellular phone networks and compete against multiple users in the next cubicle or the next state. The game can run all day in the background as users go about their daily routines while earning points and propelling their avatars as they walk to the copy machine, take coffee breaks or walk the dog.

The lack of daily mild exercise is largely responsible for the world’s obesity epidemic, according to James Levine, a Mayo Clinic physician and leading authority on obesity. Levine coined the ‘NEAT’ term to cover all physical activity that is not conscious exercise. Since hitting the gym for a regular workout might be too much to expect for those returning to the fitness fold, these games encourage small, everyday lifestyle changes, such as taking the stairs instead of the elevator or parking a few spaces away from a store entrance versus driving around to find the closest spot available.

“We hope the games can increase physical activity, add a dosage of everyday fun and embed NEAT in the modern lifestyle,” Pavlidis said. “We expect an almost ‘addictive’ behavior resulting from this game, much like the habit of playing solitaire during breaks is an everyday ritual for many people. Because of the way we live today, people are sitting all the time, so moving more is always a good thing.

“The allure of computer gaming and competition with other users encourages players to make small lifestyle changes that can add up to big health benefits,” Pavlidis said.

A computer science student who was one of the first to try out the devices lost 40 pounds in five months. The games also have been a hit with early test groups and received rave reviews from players at an April academic gathering of computer scientists.

Along with the straightforward racing game, Pavlidis also recently rolled out his version of Sodoku, a logic-based numbers puzzle that has become wildly popular. In this adaptation of Sodoku, the points players earn through physical activity can be used to fill in another square on the grid, providing clues to solving the rest of the puzzle. More games designed to appeal to a variety of age groups are in the works.

Levine’s lab at Mayo Clinic in Rochester, Minn., is gauging the games’ effectiveness in a large trial experiment that began in June. Financed by an endowed fund and a National Science Foundation grant, Pavlidis hopes the game will be available to the public before the end of 2008.
