Computed Tomography (CT) Computed Tomography, also called CT or CAT Scan uses x-rays and computers to create cross sectional images (slices) through the body. These images can then be reconstructed to make 3D models

Just a telephone line connects you with the world For over a decade, computer networking has played a large part in our daily life. The ATM or Automatic Teller Machine is a familiar example. We use the ATM to withdraw and transfer cash and make other financial arrangements. The bank's central computers record and update our account information via their dedicated networks. In the same way, we can now exchange information by using the telephone network to connect our home personal computers with those of other people. As the telephone network covers most of the world, we can connect with computers almost anywhere on Earth. This allows the Internet to pool personal computers all over the world into one huge network, and that's makes it the most wide-ranging information exchange system. Internet service providers set up very high capacity computers with which their customers can exchange information. Internet providers all over the world are interconnected, and provide an electronic mail service to individual customers. Through the Internet, we can view information submitted by people worldwide, and we can exchange ideas with them directly and conveniently. In that sense, the world has become very small.
The fascinating World of the Internet To use the Internet, you first need to apply for an account with a service provider. Most providers charge a small monthly fee. Some provide such services free of charge. The Internet is a huge information bank that can provide you a wealth of information. It is also a powerful medium. It combines the power of colour, motion and sound, and reaches the whole world. For example, you can contact the website of the Hong Kong SAR Government to find weather reports, and introductions to the operations of different departments. You can even obtain application forms for various government services. On web sites created by academic organizations, you can find a whole wealth of knowledge, from science to the arts, from history to the most up to date high-tech developments. Students can find supplementary material, complete with motion and sound, for their schoolwork, making studies much more interesting. Forums on these web sites give them the chance to discuss subjects with other students all around in the world.
The fascinating World of the Internet Commercial organizations promote their services and products on the Internet. For instance, even if you are overseas, you can still tune in to Hong Kong radio programmes. Without leaving Hong Kong you can buy products from all over the world. The Internet is a powerful and cost-effective marketing channel. To ensure that their web sites will work effectively as marketing tools and that they will reach as many prospects as possible, Internet service providers try hard to make their sites attractive so that more people will enjoy visiting them. So there's a lot of entertainment information on the Internet, including sports, news on entertainment circles, horoscope, fortune telling, and even computer games. An exciting world of entertainment opens up.
Did you know? The computer provides a convenient study resource for our children. World processing programmes make writing easier. Spread sheet programmes help them process data efficiently, and also help them to develop logical thinking. The computer has become an important learning tool. If we want our children to keep abreast with the rest of the world we should encourage them to master computer skills.
Did you know? We should also pay attention to some of the potential negative effects. There is information on the Internet, just as in other media, that is not suitable for children: pornography, violence, and expressions of hatre
Some web sites provide a facility that enables people to enter "Chat Rooms" to communicate directly with other people. Some children enjoy making friends with strangers in this way, but this resource needs to be handle carefully. For we can never know the true identity of these "friends" we have never met.
Did you know? Some research has suggested that spending too much time on the computer or on-line can hinder a child's social development. We should encourage our children to engage in other healthy activities to maintain a well-balanced life style
Enjoy the World of Computers with Our Children If you do not yet know how to use a computer, start learning today! Computer programmes are very user-friendly. You don't even need to know English, because most of the commonly used programmes have Chinese versions available. Your child may be your best teacher! A basic personal computer system includes a computer, a keyboard, a monitor and a printer. You will need a modem to connect to the Internet. You do not need to buy the latest model. Most of those available on the market are good enough for family use. In many
COMPUTER IN Daily Life We are affected by robots in our daily life more then you think. NASA uses them to explore space and other planets while others use them for deep sea exploration. The military uses "robot missiles" like the cruise missile which can be programmed to independently seek out and destroy a target. The Canadian space arm is one of the more famous Canadian space robots which help deliver satellites into space. Another Canadian arm is being made right now to assemble the international space station which is now called Alpha. Police enforcement use robots in dangerous situations like when an armed gunman stays inside the house. This robot would be used to go into the house and negotiate with the suspect or disable him if necessary. Doctors use robots in brain surgery as a ultra steady hand to perform the operation. This way the hole in the patients skull can be ass small as 1/8th of an inch, this was less complications would occur. One of the most popular ways to use robots are on assembly lines where precision work has to be done. These assembly lines would build cars, bikes, and other products. Quadropledric people use robots to do simple tasks. Even our transportation is effected by robots. The sky train is also a robot, it has no driver and automatically stops at its destination. The entertainment industry uses lots of robots in theme parks and in movies. The toy industry is getting effected by robotics too. Now you can buy these new Lego mindstorms kits which allow you to design and build your own robot and then program it with your computer.

Digital Cameras - Uses and Limitations Stephen Martin presented a session on Digital Cameras, how they are used, what some of their limitations are and the advantages they have over film cameras. He showed how to take pictures and download them to the computer from a Casio QV-10A. The Casio QV-10A can store up to 96 pictures at a time. It has a small, built-in screen for viewing the pictures. You can also output the pictures to a VCR for recording to a video tape to create a video photo album. He also showed how to convert them to a different format that is a smaller sized file and useable on web pages. He also showed how to use a video camera with a "Snappy" to take pictures. The Snappy hooks between the video camera and the computer. The computer runs special software that comes with the Snappy unit. You can see the camera output on the screen and when you have a picture that you want, you snap it on the computer and it saves it as a still picture. These files can be saved in various formats for different applications.

Blackbody Radiation A dense object emits electromagnetic radiation according to its temperature. The simplest and most common way to produce electromagnetic radiation, either on or off the Earth, is to heat and object. The hot filament of wire inside an ordinary light bulb emits white light, and a neon sign has a characteristic red glow. In a like fashion, almost all of the visible light that we receive from space comes from hot objects like the Sun and the stars. The hotter the object, the more energy it emits and the shorter the wavelength at which most of the energy is emitted. Colder objects emit relatively little energy, and this emission is primarily at longer wavelengths. To better understand the relationship between the temperature of a dense object and radiation it emits, it is helpful to know just what "temperature" means. The temperature of a substance is directly related to the average speed of the tiny atoms that make up a substance. If something is hot, its atoms are moving at high speeds; if a substance is cold, its atoms are moving slowly.
Wearable computers moves to flightline The small personal computers can be worn either on the chest or hip and are being tested as a possible replacement for printed manuals currently used.“With (the) integrated electronic technical manual, the flightline mechanic will have access to a wealth of information needed to perform (his or her) duties,” said Tech. Sgt. Matt Jones, the electronic manual’s project manager.
Officials from the 116th MXG are also looking at undergoing another pilot program that will incorporate using a unique-identification system, which may benchmark the way the Air Force controls parts inventory.
SOLID STATE HARDWARE The solid state hardware provides an economical solution for harsh environments, including areas with high temperature,shock, or vibration. VersaView CE does not require shutdown, which provides the option of instant power off of the system.
