This paper present a new dynamic window function having variable or adjustable spectral characteristics. A new dynamic window function proposed in this paper is a combination of hamming, Blackman-Harris, chebwin, and Kaiser Window function. Blackman-Harris, chebwin, and Kaiser Window functions have been used to compare with the suggested proposed window function i.e. a combination of hamming, Blackman-Harris, chebwin, and Kaiser Window function. Compare observation has been done with the help of MATLAB simulation. The simulation results show that the suggested proposed window function provides better ripple-ratio, main lobe width and side lobe roll-off ratio as compared to Blackman-Harris, chebwin, and Kaiser-window function. While comparing with Blackman-Harris, chebwin, and Kaiser Window functions, proposed window function provide quite good spectral performances with a very small compromisation of one of the spectral characteristics.
Background: A variety of Odontogenic cysts frequently present in the jaws. Cysts that develop from epithelial tissues involved in tooth formation are classified as "Odontogenic" and can be inflammatory or developmental in origin. The OKC is a very different form of developmental Odontogenic cyst because of peculiar clinical behavior, distinctive origin and development, specific histopathological features, unique tendency for recurrence and disputed treatment modalities. Orthokeratinized Odontogenic cyst is a relatively rare developmental Odontogenic cyst which was initially considered as Orthokeratinized type of OKC by WHO-1992, and later on OKC as KCOT in WHO-2005 classification, but now it is designated as different entity from OKC as OOC in WHO-2017 classification of head and neck region of Odontogenic tumors. Here we present a clinically diagnosed case of maxillary sinusitis which turned out to be Orthokeratinized Odontogenic cyst on histopathological examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
