Why Employees Quit: Frustration about Co-workers

November 20, 2014 4:47 am | by Helen Kelly | Comments

When someone says I don’t like my job, there’s little hope of retaining that employee, right? Not necessarily, there’s a fair chance that 1) I don’t like my job reflects feelings of discontent rather than a clear picture of dissatisfaction, and 2) a decision to leave would be premature.

Mitigating Artifacts of JPG Compression in Digital Images

November 12, 2014 8:07 am | by David “Ski” Witzke | Comments

Far too often, people use a high compression setting, on digital cameras and flatbed scanners or in software used to make images smaller (in size), to either store more images on memory cards or to download or email images faster. Unfortunately, what many people don’t realize is that JPG (also known as JPEG, short for "Joint Photographic Experts Group") compression discards real pixel values.

The height of an individual can be determined by his/her footprint and shoeprint. The foot tends to be approximately 15 percent of the person’s average height. At times series of footprints are left at the scene of a crime forming a recognizable gait cycle. The information gathered during examination of footprints and also on closed circuit television (CCTV) may be of value for forensic application.

November 5, 2014 8:20 am | by John J. Barbara | Comments

Future data storage needs for businesses, corporations, and governments are going to far exceed the ability of current technology to provide those storage devices. Obviously, without major technological advancements, the cost of future data storage could be unprecedented. There are however, a number of technologies under development which may eventually be able to store vast amounts of information, far exceeding today’s devices.
