In this paper, an Image Encryption System by special kind of cellular automata (cellular automata with memory) and also an appropriate transition function for the cryptosystem have been proposed. Also a lossy idea is used to present a secure cryptosystem. The use of lossy method provides a secure method and it is shown that the result is resistant to(More)
In the past few years, study of securing the digital images has increased tremendously and several encryption algorithms based on Cellular Automata have been proposed to protect the digital images against different cryptographic attacks. This paper proposes a novel pixel based encryption scheme based on Cellular Automata and Galois Field. Here the random(More)
Since the behavior of cellular automata strongly depends on their rules, it is essential to find appropriate rules for a specific application. This paper concern with rule discovery in cellular automata pseudorandom number generators. In this paper, we propose a new criterion to find high quality rules for CA randomizers. We make use of the proposed(More)
The post-translational modification of proteins is critical for regulating their function. Although many post-translational modification sites have been experimentally determined, particularly in certain model organisms, experimental knowledge of these sites is severely lacking for many species. Thus, it is important to be able to predict sites of(More)
To make stable and fast walking in humanoid robot possible, lots of works has to be done including attitude estimation, dynamic stability controls, path planning and online position tracking. These processes need an exact mechanic modelling of the robot's body structure. In this paper, an evolutionary approach is used to model the human walk for a standard(More)
Due to the importance of rolling bearings as one of the most commonly used industrial machinery elements, it is necessary to develop proper monitoring and fault diagnosis procedure to suppress malfunctioning and failure of these elements during operation. For rolling bearing fault detection, it is expected that a desired time domain analysis method has good(More)
Cellular pathways involve the phosphorylation and dephosphorylation of proteins. Peptide microarrays called kinome arrays facilitate the measurement of the phosphorylation activity of hundreds of proteins in a single experiment. Analyzing the data from kinome microarrays is a multi-step process. Typically, various techniques are possible for a particular(More)
