TL;DR: In this paper, X-ray diffraction line profile analysis was performed to calculate crystallite size, microstrain and dislocation density, and it was observed that significant contribution comes from grain boundary strengthening.

TL;DR: It is observed that image fusion by MDCT perform almost similar to that of wavelets, which means that this algorithm could be well suited for real time applications.
Abstract: Image fusion by multi-resolution discrete cosine transform (MDCT) algorithm has been implemented and evaluated. The performance of this algorithm is compared with that of well known image fusion technique using wavelets. It is observed that image fusion by MDCT perform almost similar to that of wavelets. It is computationally very simple and it could be well suited for real time applications. Defence Science Journal, 2010, 60(1), pp.48-54 , DOI:http://dx.doi.org/10.14429/dsj.60.105

TL;DR: In this paper, the underlying principles of electromagnetic analysis and design, fabrication and the trends in RAMs reviewed in this paper could lead to indigenisation, and even pioneering next generation of RAM technology.
Abstract: The research in the area of Radar Absorbing Materials (RAMs) has been actively pursued for at least four decades. Although resonant RAMs were originally designed by transmission line approach, and the broad band RAMs were obtained by multilayering, the quest for ultrawide band performance has led to novel approaches such as chirality and even exploring biochemical products. It is observed that radome materials are frequently used as RAMs. The understanding of the underlying principles of electromagnetic analysis and design, fabrication and the trends in RAMs reviewed in this paper could lead to indigenisation, and even pioneering next generation of RAM technology.

TL;DR: In this paper, the authors discuss the experimental studies carried out towards the development of a flow-sensor in the optical domain to determine the presence of resin qualitatively, three different approaches have been attempted to detect the arrival of the resin flow front and these results are presented.
Abstract: Today, with cost becoming a very important factor, alternate processes for manufacturing composite structures, wherein the cost can be reduced but having similar properties to prepreg systems are being explored. National Aerospace Laboratories, India is developing the VERITy process, which is essentially a hybridization of the VARTM and the autoclave moulding process. One of the concerns in this process, especially when making large integrated co-cured structures with varying thickness, is the knowledge of the resin flow front location at all times. A network of flow-sensors, which could provide information on the flow front location, would be very useful. This paper discusses the experimental studies carried out towards the development of a flow-sensor in the optical domain to determine the presence of resin qualitatively. Three different approaches have been attempted to detect the arrival of the resin flow front and these results are presented.
