One of the more interesting pieces of technology that has been released for the laptop computer is the fingerprint reader, which makes logging into a computer so much easier. The software that HP laptops use is Bioscrypt’s VeriSoft Access Manager. By sliding one’s finger across a small metallic sensor, the software is able to read the fingerprint and determine whether that person is authorized to use the computer. If they are, the computer automatically loads up. If not, said person will have to punch a password in. Setting Up the Read More

SDLC (Systems Development Life Cycle) is the process of creating or modifying existing systems and the models and methodologies that are used in the process. In the fields of software engineering and information systems, SDLC denotes a framework of methodologies aimed at the creation of an information/software system, i.e. the software development process. SDLC covers many activities across well defined phases. These include questioning why the information system needs to be built, to charting feasibility factors, analyzing issues that are expected to crop up, zeroing in on a certain design Read More

Smart windows are next-generation windows that control light passage and increase energy efficiency of the room in which they are a fixture without having to block the view that the windows offer. Conventional "Light Control" There is a need to control the light that gets in through windows. For example, clear 'unblocked' windows in the summer means that the sun's rays can penetrate and heat the room. This will cause the air-conditioning system to work harder and thus increase consumption of electricity. On the other hand, 'blocking' these windows in Read More

The cause of a firework's explosion is a process known as oxidation. To have a successful fireworks show, there needs to be oxygen, different kinds of metals and a creative spark. However, the first two are what really are necessary for a firework to explode. Metal is ground up into tiny little fragments and then packed into the firework casing. They grind up the metal because, when large chunks of metal are oxidized, it creates a shield around the inner parts of the metal. This prevents complete oxidation. By grinding Read More

Biofuels have been one of the most talked about renewable fuel sources over the past decade. The world is now attempting to reduce its reliance on fossil fuels, which create a significant amount of pollution and otherwise harm the environment. As a result, bio fuels such as algae biodiesel, which generate less Carbon Dioxide while being burned, may be able to garner widespread support. A biofuel can have several forms: gas, solid, or liquid. The form that the fuel is stored in is based on how its base material was harvested. Read More

Casting is a mass production process which involves molten materials (such as metals, plastics or resins) being poured into a mold, allowed to solidify and then extracted for use. Casting can be thought of as a method for reproducing something – whether a mere part or a single unit by itself. Casting is a process that can be used to manufacture complex parts which would prove too expensive or time-consuming to produce using other methods such as cutting or shaping these from solid materials. Non-expendable Casting Techniques This involves the Read More

The iPhone has become a phenomenon. It one of the best looking and practical gadgets ever created and has become a hackers dream come true with many third-party applications becoming available. Initially, Apple refused to support third party apps but the iPhone Development Team created software to jailbreak Apple's lock on apps. However, Apple has recently agreed to allow developers to create third-party apps and today there are a wide variety of applications available for both the iPhone and iPod Touch. However, if you still would like to take advantage Read More
