Some aspects of modelling of roller burnishing

Roller Burnishing of Particle Reinforced Aluminium Matrix Composites

Energy and resource efficient systems often demand the use of light-weight materials with a specific combination of properties. However, these requirements usually cannot be achieved with homogeneous materials. Consequently, composites enabling tailored properties gain more and more importance. A special kind of these materials is aluminium matrix composites (AMCs), which offer elevated strengt...

Manufacturing Technology I Exercise 8 Hard Turning – Hard Roller Burnishing

Analysis of Surface Roughness and Micro-hardness in Roller Burnishing of Aluminum Alloy 6061

Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Some aspects of modelling segmentation processes

Introduction The world we live in is continually changing. The images formed on the retina in vision are a sequence of varying, shifting intensities. In hearing, likewise changes in frequency and intensity are recognised to form the basis of our detecting the underlying structure of events in the world. Research in music perception has identified the significance of change in the segmentation o...
