DF files are data definition files that may have been stored in your directory or sent to you through email. The process on how to open these files remains a constant headache for most people who encounter these types of files. It doesn’t have to be that way. There are simple steps you can take to make these things simpler for you. If you don’t feel confident enough to tackle the problem on your own, you should ask the assistance of someone with technical knowledge about software and other computer-related Read More

Mossbauer Spectroscopy is a multipurpose technique that is applied in various scientific fields including Physics, Biology, and Metallurgy. It is most useful in deriving accurate data about the chemical, structural, and magnetic properties of a material. This technique exists today due to the discovery of the resonant absorption and recoil-less emission of nuclear y-rays, now known as the “Mossbauer Effect.” Rudolph Mossbauer discovered this when he was a graduate student at the Institute of Physics at the Max Planck Institute for Medical Research in Heidelberg, Germany. He first observed this Read More

Understanding the Operations Master Roles Active Directory operates in a multi-master replication manner. What this means is that each domain controller in the domain holds a readable, writable replica of the Active Directory data store. In multi-master replication, any domain controller is able to change objects within Active Directory. Multi-master replication is ideal for the majority of information located in Active Directory. However, certain Active Directory functions or operations are not managed in a multi-master manner because they cannot be shared without causing some data uniformity issues. These functions are Read More

An electrical shunt is a component used to transfer currents away from parts of a circuit. Components used as shunts include the resistor, capacitor, diode, and gas discharge tube. The main uses for electrical shunts are to reduce current load in meters, filter out high frequencies, and protect circuits from surges. The term shunt is also used in other fields, such as medicine, to describe non-electrical devices that perform a bypass function. Shunt Types Shunt resistors, also called bypass resistors, are large metal components with very low resistance. They look Read More

The Video Home System (VHS) format was first developed by the JVC Company in the 1970s as a successor format to Beta Max. At the time, the format featured a longer playback time, faster video forwarding and rewind, and a simpler tape storage mechanism. The format would eventually become the predominant video format in the marketplace prior to the widespread adoption of DVDs. A common task that arises for owners of legacy content stored in this format is to convert VHS to DVD. Steps to Convert VHS to DVD Step Read More

The PlayStation 2 (PS2) is the top selling gaming console of all time. More than 10 years after launch in early 2000, the company continues to sell the console even though it was succeeded by the PlayStation 3 (PS3) in 2006. Sony has gone on the public record that they will continue support for the PS2 life cycle until demand for the product ceases. A common question that arises for a fan of various PlayStation 2 titles is can you play PS2 games on PS3? How to Determine if the Read More

Snakebots are the next generation robotic probes that NASA is planning to develop in order to explore other worlds. Snakebots are named such because of their ability to move like biological snakes. Furthermore, they can change their shapes in order to accomplish different tasks such as digging under the soil, climbing over obstacles, moving around a different environment, etc. The body of a snakebot is composed of 30 identical modules linked together to form a chain. A central spine will act as the communication pathway between the modules and will Read More

The most common application for reading PDF files is the Adobe Reader, but it cannot edit PDF files the way it edits Word files. Free PDF editors are hard to come by and are mainly limited to free trials of applications being sold. There are a few options that may or may not serve well depending on the user’s needs. Free Full PDF Editors To get full PDF editing capabilities as opposed to annotation, the choice of completely free tools is rather limited. However, there are a few options to Read More

JBIG2 is a relatively new image compression standard that was first published as an international standard in 2000. It was a modern option for both lossless and lossy image compression. The standard is designed to compress images better than the traditional JBIG and Fax Group 4 standards previously implemented for bi-level or black and white images. JBIG2 compression reduces files to as small as one fifth of  the size of pictures saved under traditional formats. When black and white images are compressed with the JBIG2 algorithm, compression ratios can be Read More
