Dynamical Stability and Galaxy Evolution in LSB Disk Galaxies [PDF]
, 1996 We demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global bar modes. However, they may be only marginally stable against local disk instabilities.

Dynamical Stability and Environmental Influences in Low Surface Brightness Disk Galaxies [PDF]
, 1996 Using analytic stability criteria, we demonstrate that, due to their low surface mass density and large dark matter content, LSB disks are quite stable against the growth of global nonaxisymmetric modes such as bars.

The dependence of HII region properties on global and local surface brightness within galaxy discs [PDF]
, 2008 Using B, R, and H-alpha images of roughly equal-sized samples of low surface brightness (LSB) and high surface brightness (HSB) galaxies (~40 galaxies apiece), we have explored the dependence of HII region properties on local and global disc surface ...

Text File Hiding Randomly Using Secret Sharing Scheme [PDF]
Engineering and Technology Journal, 2018 Exchange of information through the channels of communication can beunsafe. Communication media are not safe to send sensitive information so it isnecessary to provide the protection of information from disclosure to unauthorizedpersons.

Women's attitudes toward practicing cytomegalovirus prevention behaviors
Preventive Medicine Reports, 2016 Congenital cytomegalovirus (CMV) infection causes severe disabilities and developmental delays. Women's awareness of CMV is low. Only about half of healthcare providers report counseling women about behaviors to reduce CMV risk and public health ...

GLM for Image Steganography Technique [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2013 An improvement to a Steganography method for hiding data using Gray Level Images is proposed in this paper. The method is an improvement over earlier method named Least Significant Bit (LSB).

International Journal of Computer Applications, 2011 In digital steganography normally image, audio or video files are the standard cover files or the host files for embedding secret message such as text, image, audio or video. Nath et al.(2) explored the standard method for hiding secret message inside standard cover files such as image, audio or video files. In the present work we have shown how we can
