DMADV is one of two major methodologies of the Six Sigma system. The Six Sigma system is a way to improve processes in work and manufacturing and its main goal is to eliminate defects. The Six Sigma methodology has been widely used by many Fortune 500 corporations with amazing results and can be used in small groups to achieve goals or on a corporate level affecting tens of thousands of workers. The short definition of the Six Sigma system is a set of practices that improve efficiency and remove defects. Read More

The RG-59 cable is a type of coaxial cable that is used to generate low-power video connections. The cable works on two conductors that are based on a single common axis. It is also used for RF signal connections. The RG-59 cable conducts video and radio frequencies at an impedance of around 75 ohms. The RG-59 cable is used for generating short-distance communication. The cable can be used at baseband video frequencies, which is measured from the lowest count of zero and continues to the highest signal frequency. Baseband refers Read More

There are multiple ways to split a DirecTV Satellite signal. The main problem that viewers face is not being able to see a separate channel on each television sharing the signal. If this is not an issue for the setup, then the following options are available for those who wish to continue: Method One – Using Optional Receiver Outputs If the televisions are not too far apart, the simplest option is to use the available outputs on the receiver to split the connection. Most modern day DirecTV receivers have the Read More

Sending email is a straight forward process, but does have some requirements. To begin with, you need to have an email address. Two of the best email clients are either Gmail or Yahoo Mail. Once you have signed up with an email account, it is easy to send an email. The first thing you’ll need is the recipient’s email address. The address will be something@emailclient.com. For example, it might be abcdefghijk@gmail.com. If that is the recipient’s email address, plug that in the “To” section of the email draft. Below that, Read More

A rectifier is a device that is able to convert an alternating current into a direct current through a process known as rectification. This device is very important because most electronic devices require direct current. Rectifiers are often used in power supplies (such as the power adapter used in laptop computers) and to detect radio signals as well as fires. A rectifier is the exact opposite of an inverter and can be seen in virtually all electronic devices. Alternating Current Alternating current is a type of electric current that alternates Read More

Television antennas are generally installed on top of buildings, which makes the entire structure susceptible to lightning strikes. In order to protect the building that the TV antenna is attached to, the antenna has to be grounded properly. Another danger of mounting a television antenna that is not grounded properly is the excessive static electricity build-up that is discharged to the base structure. Additionally, most city or local ordinances require TV antennas to be grounded in order to minimize fire hazards in residential structures. How to Ground a TV Antenna Read More

A computer case, also termed as computer chassis or cabinet, is a small enclosure or box into which all the major computer components and peripherals are fitted. Computer cases can be broadly classified into 2 different categories. Each of them is briefly discussed below. Desktop Case: Considered the most classical version of computer cases, these are primarily designed for personal/business computers that are placed on top of a desk. The basic objective of these cases is to conserve the available desk space as the monitor is placed on top of Read More

A BLOB (Binary Large OBject) is a large chunk of data which is stored in a database. A BLOB differs from regular database data in that it is not forced into a certain structure. A normal database field might be structured to be 14 characters long and only accept lowercase letters. A BLOB field is not usually restricted in content type and content can be several gigabytes in size. Normal database fields have space allocated for them whether they are utilized or not. BLOB fields are only allocated space when Read More

Fireworks are, in the simplest terms, aeronautical explosives that are used for entertainment and celebratory purposes. Fireworks have been used for nearly a thousand years and are available in hundreds of different shapes, sizes, and colors. There are also various forms of fireworks that burn in different ways. Sparklers, for example, simply produce sparks when ignited and do not explode at all. Skyrockets, on the other hand, are much larger and are launched high into the sky, where they explode into various shapes and colors. Fireworks are used all around Read More

Tire pressure monitoring systems (TPMS) are used to detect the air pressure of automobile tires and provide warnings to the operator when the pressure is low. They are electronic devices and are also referred to as tire pressure indication systems depending on the device’s manufacturer. Most variants of the system display a warning light to the vehicle operator, and some also display the real time pressure of each tire on the automobile. What Are the Types of Tire Pressure Monitoring Systems? There are two types of tire pressure monitoring systems: Read More
