In this paper, design and analysis of a new type of Substrate Integrated Waveguide (SIW) antenna and a pair of inverted complimentary U-shaped slots are proposed with considerable effect of a single reflection cancelling via (RCV) at the center of the structure. The position of the complementary slots with respect to the RCV is varied for getting the resonant frequency within microwave x-bands (≈11...
Although hydroxyapatite based bioceramics exhibit excellent bioactivity, their poor mechanical properties limit their applications to primarily as non-load bearing components and surface coating. The current investigation is aimed to mitigate this problem. In the present study, nanocrystalline undoped and 5mol% Mn, Mg and Zn-doped HAp powders are synthesized by mechanical alloying at room temperature...
Software development life cycle models form the heart of software engineering since software development process spans the life cycle of any given project. Even though the waterfall model forms the basis of all software development life cycle models, the demand for new models with design and implementation occurring in parallel is on the increase. This research aims at the proposal of a vision oriented...
In this study, an attempt has been made to study an image retrieval technique based on the combination of Haar wavelet transformation using lifting scheme and the colour histogram (CH) called lifting wavelet-based colour histogram. The colour feature is described by the CH, which is translation and rotation invariant. The Haar wavelet transformation is used to extract the texture features and the...
