Abstract

Two dimensional discrete prey-predator interactions in the closed first quadrant 2 R are investigated in this paper. The dynamics of the system such as the existence of non negative equilibria, local stability of the equilibrium states are analyzed. It is seen that the system goes through Flip and Neimark – Sacker bifurcation about axial and positive equilibrium states with prey growth rate as the bifurcation factor. It is also observed that the model is sensitive to the initial conditions and the parameter values.With the natural growth rate parameter, bifurcation diagrams are obtained. Numerical results demonstrate not only the essential outcomes of analytical observations but also give an idea about the complexity of the discrete model.

Keywords: Prey – Predator Model, Stability, Discrete Time, Equilibria, Limit cycle, Flip bifurcation, Neimark – Sacker bifurcation, Chaos. AMS Subject Classification: 34A08, 34K18, 39A12, 92D25.

International Journal of Computational Engineering Research, Volume 09 ~ Issue 04 (April – 2019)

Abstract

Rhodobacter litoralis is an important photosynthetic prokaryote in terms of the structural and functional light reactions. It has a greatly diverse metabolism as it has the ability to live through cellular respiration, fermentation, photosynthesis, or photoautotrophic growth. Therefore, it can be used as a potent bioremedial agent. An attempt was therefore made to evaluate its effectiveness in bioremediation of waste water, particularly contaminated with sewage waste. Certain physico-chemical parameters for the assessment of quality of sewage contaminated water were considered, including pH, BOD, nitrates, sulphates, chlorides and ammonia. Parameters were tested before, during and after the bioremedial treatment with Rhodobacter litoralis. A comparison amongst three stages of testing was made, which has been of great help in assessing the bioremedial impact of Rhodobacter litoralis............

Abstract

Hypertension is the main reason of deaths and ranks next to diabetes amongst the chronic diseases. High blood pressure or hypertension is the generally occurring public health problem and often referred to as a silent killer. Hypertension and atherosclerosis are primarily responsible for cardiovascular diseases globally. Drug remediation solely might not be passable enough for treatment of either the hypertension or atherosclerosis without the involvement of any dietary management. Nevertheless sesame and garlic mix become a vital part in course of the cardiovascular disease therapy. Since sesame seeds have shown to have good nutritious source of manganese, calcium........

International Journal of Computational Engineering Research, Volume 09 ~ Issue 04 (April – 2019)

Abstract

Cloud computing is based on network and computer applications. In cloud data sharing is an important activity. Small, medium, and big organizations use cloud to store their data in minimum rental cost. At present time, cloud is used by most of the customers because of its services. Therefore, security or privacy of data and data management is to be done properly. In this paper we're going to take the information and distribution it into two distinct part so as to take the security at two levels. At first level, i.e. at hosting site, the image, audio & video files in which the information is encrypted or hidden using steganographic technique. At second level i.e. at cloud,the reference of these files or keys are stored.For data security at cloud, by using steganographic and obfuscation technique where going to address two algorithm, the RSA and DSA algorithms. RSA algorithm can be used for encryption while DSA is used for checking data alteration.

Keywords: Steganographic, Obfuscation, Cloud, Algorithm, RSA, DSA.

Abstract

Collapsible roof system is a new emerging technology of structural system which will be used for auditoriums according to the weather condition. It will open during fair and closed weather. Artificial neural network and fuzzy logic system are very effective and fast process of optimization which will be used for the non-linear data. Optimization is a process of selecting best solution from the set of available alternatives. The proposed ANN model is trained with observation data for predicting the optimization of collapsible roof. In this research work, optimization of collapsible roof structural design using real coded of artificial neural work and fuzzy logic from the MATLAB............

Abstract

Ultrathin tantalum nitride (TaNx) filmswere deposited on glass substrates by dc reactive magnetron sputtering at different thicknesses andanalyzed the structure,compositional, microstructure, surface morphology, optical and electrical properties. X-ray diffraction results showed that the deposited films have amorphous structure. The surface morphologies of the films were significantly affected by the films thickness. The RMS roughness of the films increased from 0.5 to 1.3nm by increasing the filmsthickness.The transmittance of the films decreased with increasing the films thickness.
