Iris recognition refers to the technology that identifies an individual through the photographing and verification of his/her eye. Iris recognition is a biometric technology and is also referred to as biometric security. Iris authentication is becoming increasingly popular as a security measure in industry, government, and military organizations due to its high degree of accuracy, safety, and simplicity (in terms of using it). How does Iris Recognition Work? Iris recognition combines pattern recognition, options, and computer vision technologies to authenticate an individual’s identity. First, the system takes a zoomed-in picture Read More

An Apple MacBook can last some time without the keyboard getting damaged. If the keyboard gets damaged (for e.g. a loose key falls out of the setting) or the user simply wants a new keyboard, he/she will need to replace the keyboard in question. The MacBook has a fairly simple case that users with the correct tools can service. Note: Later MacBook computers have a “unibody” construction that gives the appearance of tighter seams that are difficult to pry open. Choosing to replace a MacBook keyboard outside of the warranty Read More

Solidworks refers to a powerful 3D modeling program used in Computer Aided Design (CAD). The models produced from it are used in a number of ways to simulate the behavior of the real part or assembly as well as checking basic geometry. It is also used for advanced part assembly, physical dynamic calculation, surfacing, enhancing large assembly performance, and many other applications. The following is a tutorial that one may use to learn basic facts on creating solid features needed to build the major functional parts and how to assemble Read More

The Large Hadron Collider, abbreviated as LHC, is an energy particle accelerator or collider instrument. It is the world’s biggest instrument used by scientists to study and examine the smallest identified particles; which are the primary building blocks of everything. The Large Hadron Collider is a worldwide project with UK playing the major part. This project will transform humans understanding about the microscopic world packed with atoms, the elementary laws of physics and the darkest secrets of the Universe. Large Hadron Collider was designed for a purpose of having a Read More

A mini USB, also known as a Type B USB cable or USB 1.0 connector, is a type of USB cable and port that is designed for mobile devices, such as smartphones, MP3 players, and cameras. Mini USB cables work in the same way that regular USB cables do, in that they carry power from the computer to a mobile device as well as data in both directions from a mobile device to a computer and vice versa. Mini USB cable endpoints are smaller than regular USB cable endpoints, but Read More

A speaker is a device that converts electrical signals into actual sound. Speakers accomplish this by using a magnetic reader or antenna to receive an electrical signal from a radio station or magnetic storage device. The magnetic reader is then connected via a wire to an electromagnet that can be turned on and off in accordance with the electrical signal. The electromagnet is then used to pull a diaphragm back and forth, which moves the air around it. As the air moves, the listener’s ears and brain are able to Read More

Internet Explorer Stored Password Recovery refers to a system used by Internet Explorer to temporarily store usernames and passwords for the user’s convenience.

BD+ is an interpreter mechanism or virtual-machine-based technology designed for BD-ROM disc security. BD stands for Blu-ray Disc (also known as Blu-ray) and is a type of optical storage media having the same dimensions as the standard CD. Blu-ray Disc was developed by the Blu-ray Disc Association. Blu-ray Disc uses a blue-violet laser unlike standard DVD, which uses a red laser. Blue laser has a much shorter wavelength and can thus be used to store much more data than a DVD. BD+ is essentially a mechanism or security technology that Read More
