What is Video Conferencing? Video conferencing is a set of interactive telecommunication technologies which allow two or more parties in different locations to interact via two-way transmission of audio and video simultaneously.
The development of communication technology bring changes in the process of delivering information. Shape information conveyed not only audio but also visual. Video conferencing uses telecommunications of audio and video to bring people in different places held a joint meeting. Read more…
In business, information technology has a significant effect, recorded business transactions on-line, prepared and at about the same (real-time) result of processing or information can be seen, as is commonly done at the bank’s customers conduct transactions at ATM (automated teller machine).
In the era of the 70s a management expert who predicts that the master of human resources and information will conquer the world. This can be proved that towards the 21st century countries and companies that excel are those who from the beginning has been to apply information technology as a tool to compete. Information technology has become a weapon (tool) in the company’s business processes that can make rapid flow of information runs internally and eskternal. Read more…
Nuclear Power Plants (NPP) grouped by type of reactor used. But there are also nuclear power plants that implement independent units, and it could use different reactor types. In addition, following several types of reactors, in the future are expected to have a passive safety system.
Fission Reactors
Fission power reactors generate heat by nuclear fission of uranium and plutonium isotopes fissil. Furthermore, fission power reactor further grouped into: Read more…
What is Nuclear Power Plant? Nuclear Power Plant (NPP) is a thermal power station where the heat generated from one or more nuclear reactor power plants. NPP included in the base load power generation, which can work well when the power output is constant (although boiling water reactor to drop to half power at night). Power generated per unit of power ranging from 40 MWe to 1000 MWe. New units being built in 2005 has the power of 600-1200 MWe.
Until 2005 there were 443 licensed nuclear power plant in the world, with 441 of them operate in 31 different countries. The entire reactor was supplying 17% of world power. Read more…
What and how effect and impact of nuclear radiation, if a nuclear explosive? Let us look at the latest case, on nuclear emergency in Japan, after the earthquake and tsunami in Japan on March 11, 2011 yesterday. Nuclear emergency in Japan warned on nuclear power plant accident at Chernobyl, Ukraine, on April 26, 1986. Accident caused by explosion of a nuclear reactor number four at the plant had become the biggest accident in history.
As many as 4,000 people were killed in the accident, and victims continue to fall after suffering from various diseases caused by exposure to radiation. Read more…
Post-Tsunami, March 11, 2011, the Government of Japan has set a nuclear emergency for one of its nuclear reactor in Fukushima, Tohoku, about 250 km north of Tokyo. After an earthquake rocked with the power of 8.9, a nuclear reactor plant number 2 in Fukushima 1, which managed the Tokyo Electric Power Co.. experiencing problems with cooling facilities and should be turned off for safety.
Although it has been turned off, the demise of the cooling system becomes a serious concern. Therefore, nuclear reactors already shut down still require cooling process. To anticipate the worst, the government has asked residents near a nuclear reactor is to evacuate to a safe radius. Read more…
Digital Information Technology or Digital Communications Technology is the technology of computer-based electrical signal, the signal is discontinuous and use the binary number system. It will establish the binary codes that represent certain information. Here are the advantages of digital information technology:
In accordance with computer technology
After going through the process of digitalization, information received will be turned into a series of binary numbers that make up the information in the form of digital code. The digital code will be able to be manipulated by computers. An example is the video camera image that has been converted into digital form. Digital form representing the picture elements (pixels). Elements of the images could be manipulated by computers. So that we can create a certain effect on the image and can also improve the image quality is considered poor. Its manipulation form could be the addition of light intensity on the image, so that the existing image becomes lighter or darker, increase the sharpness of the image that lack focus, and improving color in certain parts of the image.
