A steganalysis by adjacency pixel bits structure

Computers & Electrical Engineering, 2013
Embedding of confidential data in the least significant bit of an image is still an attractive method of steganography. Utilizing the full capacity of cover images by embedding one bit of data per pixel, using methods such as LSB flipping or LSB matching, usually decreases the security, making the algorithm vulnerable to steganalytic attacks. And then,

Polytomoencephalography of the Optic Chiasm and Adjacent Structures

Radiology, 1975
The addition of polytomography considerably increases the sensitivity of pneumoencephalography. The chiasmatic area lends itself particularly well to investigation by polytomoencephalography. In a series of 28 patients, the transverse dimension of the optic chiasm ranged from 4 to 20 mm, with a mean of 18 mm.

Contact between Adjacent Structures

Journal of Structural Engineering, 1991
In this paper, the static contact forces developed between adjacent structures are studied. Activation of a unilateral contact situation between adjacent buildings can be caused by external horizontal loading, e.g., the case of a design static loading representing an earthquake motion as in the pseudostatic method of analysis for earthquake‐resistant ...

Higher order structure of the PCM adjacent to the centriole

Cell Motility, 2003
AbstractThe centrosome is the major microtubule organizing center in most animal cells. This cytoplasmic organelle consists of two components : a mature centriole (or a pair of centrioles) and a mass of pericentriolar material (PCM). The PCM has been described as either a cloud of material that encases the entire centriole or as a cluster of proteins ...

Adjacencies for Structuring the Digital Plane

2012
We study graphs with the vertex set ℤ2 which are subgraphs of the 8-adjacency graph and have the property that certain natural cycles in these graphs are Jordan curves, i.e., separate ℤ2 into exactly two connected components. For the minimal graphs with this property, we discuss their quotient graphs, too.

Computed tomography of the paranasal sinuses and their adjacent structures

Computerized Tomography, 1977
Forty-five computed tomographic examinations were performed on 34 patients with diseases of the paranasal sinuses and their adjacent structures. Coronal sections were obtained in addition to transverse axial tomographic sections. Evaluation was made whether CT could provide more informations compared with plain roentgenography and whether there were ...

Computed Tomography of the Ethmoid Labyrinth and Adjacent Structures

Annals of Otology, Rhinology & Laryngology, 1987
The architecture of ethmoid labyrinths as well as their relationships with adjacent structures are reviewed, giving special emphasis to the anatomic variants common in this area. The study was performed on six young normal subjects who were submitted to high resolution computed tomography.

Sonographic anatomy of the supraspinatus tendon and adjacent structures

Skeletal Radiology, 1997
To depict the detailed sonographic pattern of the normal supraspinatus tendon and adjacent structures. Pathologic findings in these structures. Pathologic findings in these structures are well described, but knowledge of their sonographic anatomy is relatively limited.A new position for sonography of the shoulder was adopted that permits good ...
