Fishery resource management with migratory prey harvesting in two zones- delay and stochastic approach.

In this work, we looked at a two-zone aquatic habitat where both prey and predators can access the zones. The prey alternates between two zones at random. The growth of prey in the absence of a predator is believed to be logistic in each zone. The inner steady state is determined. Around the interior steady state, the deterministic model's local and global stability is investigated. Furthermore, a stochastic stability study is performed in the neighbourhood of a positive steady state, using analytical estimates of population mean square fluctuations to investigate the system's dynamics in the presence of Gaussian white noise.

A Review Article on Wireless Sensor Networks in View of E-epidemic Models.

Epidemic simulations have recently been used to model the dynamics of malicious codes in the network of wireless sensors. This is because of its open existence, which offers a simple target for malware attacks aimed at disrupting network operations or, worse, causing complete network failure. The Susceptible-Exposed-Infectious-Quarantined-Recovered-Susceptible with Vaccination compartments models like SIR-M, SEIRV, SEIQRV, SEIRS, SITR, SIR with delay are studied by various authors and some of such models that characterize worm dynamics in WSN. After a concise presentation of the wireless sensor network, some primary research consequences of e-pandemic models (of various researchers) are given and assessed. At that point the uses of wireless sensor network in the clinical wellbeing, agribusiness, and military, space and marine investigation are laid out. What's more, we break down the upside of wireless sensor network in these sectors. In this review article, we sum up the fundamental factors that influence the uses of wireless sensor networks in view of e-epidemic models and revived some epidemic models and also discussed some conceivable future works of different epidemic wireless sensor models.
