One of the critical parts in rotating machines is bearings and most of the failure arises from the defective bearings. Bearing failure leads to failure of a machine and the unpredicted productivity loss in the performance. Therefore, bearing fault detection and prognosis is an integral part of the preventive maintenance procedures. In this paper vibration signal for four conditions of a deep groove...
Nearest Neighbor Classifiers demand high computational resources i.e, time and memory. Two distinct methods are followed by researchers in Pattern Recognition to reduce this computational burden. The first method is reducing the reference set or training set and the second method is dimensionality reduction which are referred as Prototype Selection and Feature Reduction(a.k.a Feature Extraction or...
Twitter is one of the most popular Online Social Networks (OSN). It is used by millions of users worldwide everyday. Due to the text limitation on Twitter (140 characters per tweet), URL (Uniform Resource Locator) shortening services are widely used, however they are not free from risks. Shortened URLs are completely different from the original URLs, and hence users have no idea where the short URLs...
This paper is a review of the literature on detection of lung cancer using medical content based image retrieval. Lung cancer is prominent cancer as it states large number of deaths of more than a million every year. It creates need of detecting the lung nodule at early stage in Computer Tomography medical images. So to detect the occurrence of cancer nodule at early stage, the requirement of methods...
