The rotating machinery is a common class of machinery in the industry. The root cause of faults in the rotating machinery is often faulty rolling element bearings. This paper presents a novel technique using artificial neural network learning for automated diagnosis of localized faults in rolling element bearings. The inputs of this technique are a number of features (harmmean and median), whic...

Computer science owes a huge debt to biological systems. The field itself came about largely as an attempt to understand and replicate the function and abilities of the brain, a complex biological creation. From this early lineage has sprung many subfields derived largely from biological metaphors: computer vision, neural networks, evolutionary computation, robotics, multi-agent studies, and mu...

When a conventional black-and-white receiver is tuned to transmissions conforming to the NTSC color standards the receiver responds fully to the first signal (the “brightness signal”) and recreates from it an image in black-and-white having a quality equal (or superior) to that provided by present black-and-white standards. Because of the nature of the chromatic signal, no normally perceptible ...

It's often a balancing act to determine if patients should be admitted to the hospital or receive observation services as an outpatient, but it's critical to get it right the first time so the hospital will get appropriate reimbursement and avoid having money taken away following audits. Reimbursement is much lower for observation services, but if a patient is admitted inappropriately, Medicare...

Offshore outsourcing of services has caught the imagination of corporate boardrooms. Several Fortune 100 firms in North America, Northern Europe, and Japan have significant offshore outsourcing initiatives in place, reaping their benefits ahead of their competitors. The rush towards offshore outsourcing has turned into a stampede, fueled by access to lower-cost, high-quality labor, enabled by c...
