Here’s what we know for sure. On the afternoon of Friday, 3 October 2014, Pyrros A. Telionis got a telephone call from the U.S. government’s Defense Threat Reduction Agency (DTRA). He was sitting in a featureless cubicle in Blacksburg, Va., that would have made the cartoon office drudge Dilbert feel right at home. The voice on the phone was brisk and professional. And highly specific. Could Telionis...
In this paper a novel approach is implemented for investigation of failures in Stork bottle filling machines. Fuzzy based system is used to detect the abnormalities present in machine by using time and frequency domain statistical features. Statistical analysis of vibration data determined the gearbox failure which correlated with engineer's findings. The method used has shown promising results to...
Copper losses have always been a problem in design and implementation of electric machines. The appearance of electrical vehicles and unavailability of reliable mobile energy sources in recent years have put more stress on this fact. In this paper, simple mathematical approach using differential calculus has been used to find optimum set of currents in a brushless DC motor for copper loss minimization...
Recommender systems suggest resources to users based on collaborative filtering techniques, typically by exploiting correlations between individual user ratings of the resources they are interested in. Tags are a new form of metadata increasingly used in social bookmarking sites by users to annotate bookmarked resources. Our goal is to harness the implicit knowledge contained in these tags to improve...
