Steganalytic techniques are used to detect whether an image contains a hidden message. By analyzing different image features between stego-images (the image within which information is hidden) and cover-images (the Image in which information is to be hidden), a steganalytic system is able to detect stego-images. In this paper, we present a new method in LSB embedding by avoiding the change of s...

I summarize some results from the recent CO survey of late-type, low surface brightness (LSB) spiral galaxies by Matthews et al. (2005). We have now detected CO emission from six late-type, LSB spirals, demonstrating that despite their typical low metallicities and low mean gas surface densities, some LSB galaxies contain a molecular medium that is traced by CO. We find that the CO-detected LSB...

A low-power 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) with split-capacitor, nonbinary-weighted, and multiple-least-significant-bit (LSB)-redundant capacitor digital-to-analog converters (CDACs) is proposed. The proposed SAR ADC nonbinary-weighted multiple-LSB-redundant CDACs has an optimal mechanism for correcting the bit error decisions due to noise incom...

In modern stream cipher, there are many algorithms, such as ZUC, LTE encryption algorithm and LTE integrity algorithm, using bit-component sequences of p-ary m-sequences as the input of the algorithm. Therefore, analyzing their statistical property (For example, autocorrelation, linear complexity and 2-adic complexity) of bit-component sequences of p-ary m-sequences is becoming an important res...

The highest way to protect data from intruder and unauthorized persons has become a major issue. This matter led the development of many techniques for security, such as Steganography, Cryptography, Watermarking disguise data. paper proposes an image steganography method using Least Significant Bits (LSB) technique XOR operator secret key, through which key is transformed into one-dimensional b...

We present UBV I and Hα images of a sample of Low Surface Brightness (LSB) disk galaxies. These galaxies are generally late types, if they can be sensibly classified at all. However, they are not dwarfs, being intrinsically large and luminous. The morphology of LSB galaxies is discussed in terms of the physical interpretation of the Hubble sequence. Galaxies with high contrast relative to the s...

We propose a time-to-digital converter (TDC) using a charge pump and a SAR-ADC. With this architecture, high time resolution is attainable by increasing the charging current or reducing the sampling capacitance. Thus, the resolution limitation in a delay-chain TDC does not exist. We propose to use a SAR-ADC attributed to its characteristics of compact structure, scalability, low power consumpti...

Imperfect transmission of satellite imagery results in the loss of image lines. This paper proposes a novel error concealment technique using LSB-based watermarking. We generate block description information and insert it into the LSB bit plane of the image. Missing lines after transmission are restored by extracting this block description information. Simulation results show outstanding perfor...

Using the refurbished 305m Arecibo Gregorian Telescope, we detected 43 low surface brightness (LSB) galaxies from the catalog of O'Neil, Bothun, & Cornell (1997a). The detected galaxies range from 22.0 mag arcsec −2 ≤ µ B (0) ≤ 25.0 mag arcsec −2 , with colors ranging from the blue through the first detection of a very red LSB galaxies (B−V = −0.7 to 1.7). The M HI /L B of these galaxies ranges...
