Effect of machining parameters on the tool wear in drilling of 3D PF C/C composite
Abstract: Carbon–carbon (C/C) composites are broadly used in aerospace, defence, shipbuilding, chemical, and nuclear industries owing to their high strength-to-weight and stiffness-to-weight ratios. However, they are brittle, anisotropic and non-homogeneous in nature, making them difficult to machine. Incorrect machining parameters can cause defects such as burrs, delamination, and fibre bundles pullout. This paper aims to study the hole surface and tool wear during drilling of 3D pierced fabric (PF) carbon-carbon (C/C) …

Comparative Study of Structure-from-Motion Algorithms 3D Shape Reconstruction
Abstract: 3D shape reconstruction from multiview photographs and video sequences (2D images) is an active area of research. Existing face recognition systems are based on 2D facial images and exhibit well-known deficiencies. Accordingly, the face recognition research is gradually shifting from classical 2D to sophisticated 3D or hybrid 2D/3D. Currently the 3D reconstruction algorithms may be grouped in to four categories. These are shape-from-X, 3D morphable model (3DMM), structure from motion …

Automating Acquisition through SOUL 3.0
Abstract: Library automation is an integral part of the development process of any library or resource center. Traditionally this includes automation of acquisition, serialization, cataloging and circulation. But most libraries do list entries of reading material and display them via OPAC. These libraries have been equally successful in computerized issues and returns. But the real difficulty lies in the automation of acquisition activities. It is forgotten that cataloging begins with acquisition. …

Delay Minimization of 3 Cascaded Inverters with the Help of Logical Effort and Transistor Sizing
Abstract: With logical effort minimum delay of the path can be estimated by only knowing number of stages, path effort, and parasitic delay without the need to assign transistor sizes. This is superior to simulation where delay depends on sizes and you never achieve certainty that the size selected would offer minimum delay. In this work 3 cascaded inverters is being sized in the ratio 1:2:3 to achieve minimum propagation delay …
