A robonaut is a robot designed to assist humans in space exploration missions. As temperatures in space can range from -100 degrees Celsius to 120 degrees Celsius, astronauts need to wear space suits that cost 12 million dollars apiece. They also need at least a few hours of preparation before they can respond to any emergencies like external repairs on an international space station caused by collisions with space matter. Because of these inherent difficulties that human astronauts face, robonauts that can be fielded in far less time and with Read More

The Windows Media Video format, or WMV, was designed by the Microsoft Corporation to support watching movies and Internet videos on personal computers. The WMV format allows large video files to be reduced in size or compressed to better support use over the Internet or a network while maintaining quality. In order to play WMV files on Windows computers it normally requires the appropriate CODEC or software application such as Windows Media Player to support playback. For use on non-Windows computers, WMV files will normally need to be converted to Read More

A satellite dish is a parabolic antenna used to pick up and send out electromagnetic signals, typically relayed by communication satellites orbiting around the earth. It can be used for data, radio, or television. They come in various sizes and designs. They are also commonly used to receive satellite television. A satellite dish captures satellite television signals that reach a viewer's house. A standard dish consists of a bowl-shaped surface and a central feed horn. A feed horn is an antenna used to channel signals between the transceiver and the Read More

Throw Mechanism When an exception, which is desired to be handled, is detected, it is thrown using the throw statement. It can be used in any one of the following form: throw(exception) ; throw exception ; throw ; // used for re-throwing an exception The object passed to the throw statement may be of any type, including constants. It is also possible to throw objects not intended for error handling. When an exception is thrown, it will be caught by the catch statement associated with the try block, i.e., the Read More

Opera Browser is a web browser that Opera Software provides. It gives users many advanced features that other web browsers simply do not have. For example, Opera Browser features tab stacking, which allows users to drag and drop tabs on top of each other to save space. Opera also features Opera Unite, which allows users to share content with others without having to upload it to a server. Opera also has Opera Turbo, which speeds up connections on slow networks and has a built-in password manager and hundreds of available Read More

Vision Station is a computer display technology developed by Elumens that provides 180 degrees of viewing angle for its users. Current computer screens have at most a 50-degree field of view and needs the user to move the controller in order to see the images that are not on the screen. This motion is unnatural because in the real world, users use their peripheral vision to see things beyond the direct line of sight. This new display technology will address this limitation of standard computer monitors. With Vision Station, users Read More

VoIP spam or Spam over Internet Telephony (SPIT) is one of the foreseen future forms of spamming that Internet authorities are preparing for today. With the increasing use and dependence on the Internet for communications and data transfer, malicious software programmers have taken advantage by creating VoIP bots with the ability to harvest data and advertise massively at a very small cost. These advertising methods include email spams, SPIMS or spams over instant messaging applications, malicious bots that generate pop up ads, initiate redirects, etc. With the inevitable popularity of Read More

Photolithography is the process of making integrated circuits through optical erosion. Rather than directly cutting into an integrated circuit, photolithography is used due to its ability to perform more precise incisions. Photolithography is a highly complex technique and requires both an extremely clean substrate surface and ideal temperature conditions. It can only be used to produce flat surfaces. Despite this, photolithography is the most popular technique used to make integrated circuits. How Photolithography Works Photolithography begins with a substrate that has been previously cleaned with water or a chemical and Read More

SAN zoning is a method of arranging Fibre Channel devices into logical groups over the physical configuration of the fabric. SAN zoning may be utilized to implement compartmentalization of data for security purposes. Each device in a SAN may be placed into multiple zones. Hard and Soft Zoning Hard zoning is zoning which is implemented in hardware. Soft zoning is zoning which is implemented in software. Hard zoning physically blocks access to a zone from any device outside of the zone. Soft zoning uses filtering implemented in fibre channel switches Read More
