Drilling Effect on Fiber Composites: A Review
Abstract: Composites laminates show immense mechanical properties like strength-to-weight ratio, damage tolerance, fatigue and corrosion resistance therefore conventional materials are replaced by composites in many areas such as automobile and aircraft structure. Machining of composites is very difficult than machining of a conventional material because composites are inhomogeneous and extremely abrasive. In production drilling is important machining process used to produce hole for riveted and bolted joint. There are many improvements …

Comprehensive Review and Analysis of Improved Filtering Methodology Based Image De-noising System
Abstract: A digital image is often ruined by noise that comes from the process and equipment used to make it or that is added to the image while it is being sent. Different kinds of noise, like impulse noise, uniform noise, Salt-and-Pepper noise, and additive Gaussian noise, can show up in images. Using a good image de-noising method, noise can be taken out of an image to bring back its details. …
