A new HI catalog of Low Surface Brightness galaxies out to z=0.1 Abstract. Using both the Arecibo 305m and the Nançay decimetric 100-m class radio telescopes, we have observed the H i line of 116 Low Surface Brightness (LSB) galaxies from the Bothun et al. 1985 subset of LSB galaxies in the Uppsala General Catalog. The observations had a detection rate of 70%, resulting in the new determination...

This paper proposes a new approach for information hiding in RGB color images based on 3 new techniques 1) A new hybrid feature (line /edge /boundary /shape) detection technique combining Canny and Hough transform for bifurcating an image into edge and smooth areas 2) Two Component based Least significant bit (LSB) Substitution Technique for hiding encrypted messages in edges of images 3) An Ad...

Fifteen generations of selection were conducted to study responses for litter size at birth (LSB), weight at weaning of standardized litter (LWW), and individual body weight at 8 wk of age (BW8) using golden hamsters as an experimental model for pigs. The experiment involved three lines: selection on an aggregate breeding value of LSB, LWW, and BW8 (line W); selection on an aggregate breeding v...

Image steganography is the best aspect of information hiding. In this, the information is hidden within an image and the image travels openly on the Internet. The Least Significant Bit (LSB) is one of the most popular methods of image steganography. In this method, the information bit is hidden at the LSB of the image pixel. In one bit LSB steganography method, the total numbers of the pixels a...

This paper proposed a new steganalysis method against least significant bit (LSB) matching for images with high noise component which is considered more difficult for steganalysis than images with low noise component. First we calculate the sum of curvature of images histogram as discriminative feature which will reduce after LSB matching. Then, the calibration mechanism is introduced to reduce...

Viscous redistribution of mass in Milky Way-type galactic disks is an appealing way of generating an exponential stellar profile over many scale lengths, almost independent of initial conditions, requiring only that the viscous timescale and star formation timescale are approximately equal. However, galaxies with solid-body rotation curves cannot undergo viscous evolution. Low surface brightnes...

The advantages of Least-Significant-Bit (LSB) steganographic data embedding are that it is simple to understand, easy to implement, and it results in stego-images that contain hidden data yet appear to be of high visual fidelity. However, it can be shown that under certain conditions, LSB embedding is not secure at all. The fatal drawback of LSB embedding is the existence of detectable artifact...

We investigate whether a correlation exists between the concentration (2̧00) and spin (λ) parameters of dark matter haloes forming in ΛCDM N-body simulations. In particular, we focus on haloes with virial masses in the range 10 6 Mvir/h M⊙ 6 2×10 , characteristic of the hosts of Low Surface Brightness (LSB) and High Surface Brightness (HSB) galaxies. Our analysis demonstrates that 2̧00 and λ are ...

Salah satu manfaat dari perkembangan audio yaitu dengan menyisipkan suatu pesan rahasia dalam media digital. Dengan menggunakan teknik steganografi, yang akan menyembunyikan atau data pengirim ke penerima. metoda LSB digabungkan MPEG SAOC. SAOC memiliki kemampuan mereproduksi multikanal, sehingga mampu dikombinasi steganografi LSB. Maka dihitung jumlah karakter, SNR dan ODG dapat ditumpangi beb...
