What's more, the advancement of protective arrangements is lingering behind. To guarantee a safe and dependable cloud condition it is fundamental to recognize the restrictions of existing arrangements and imagine bearings for future research. Cloud computing changed our general surroundings. Presently individuals are moving their information to the cloud since information is getting greater and should be available from numerous gadgets. In this manner, putting away the information on the cloud turns into a standard. In any case, there are numerous issues that counter information put away in the cloud beginning from virtual machine which is the intend to share assets in cloud and completion on cloud stockpiling itself issues. In this paper, we present those issues that are keeping individuals from receiving the cloud an...

It is a product of selected, beneficial and live microorganism which help to improve plant growth and productivity or, mainly through supply of plant nutrients. Phosphate solubilizing organisms play an important role in growth of the plants. The bio inoculants improve the shelf live and survivability of microbes in soil and stimulate the growth of the plants. The present study was to extract the phosphate solubilizing bacteria from coconut husk and its formulation in growth of pulses.

However, practical problems often fail to satisfy these assumptions and the conventional Kalman filter suffers from poor estimation accuracy. This paper proposes a modified Kalman filter to address both the problems of delayed measurements and non-Gaussian noises. The proposed filter is updated using correntropy maximization criterion, which is suitable for non-Gaussian noise environments. It falls short of a closed-form solution due to analytically complex equations that appear during the filtering. We use fixed-point iterative method to find an approximate solution. The delayed measurement problem is addressed by implementing a likelihood-based approach to identify the delay. Based on the identified delay information, the measurement is used to update the desired state in the subsequent past instant. To perform real-time filtering, the estimated state is further updated up to the current time instant using the process dynamics. The performance analysis validates the improved accuracy of the proposed method compared to the ordinary Kalman filter and its existing extensions.
