in this paper, we have proposed a study on controllability and optimal harvestingof a prey predator model and mathematical non linear formation of the equation equilibriumpoint of routh harvest stability analysis. the problem of determining the optimal harvestpolicy is solved by invoking pontryagin0s maximum principle dynamic optimization of theharvest policy is studied by taking the combined h...

Many problems of practical interest can be solved using tree search methods because carefully tuned successor ordering heuristics guide the search toward regions of the space that are likely to contain solutions. For some problems, the heuristics often lead directly to a solution| but not always. Limited discrepancy search addresses the problem of what to do when the heuristics fail. Our intuit...

Limited observability is the assumption that economic agents can only observe a finite amount of information. Given this constraint, contracts among agents are necessarily finite and incomplete in comparison to the ideal complete contract that we model as infinite in detail. We consider the extent that finite contracts can approximate the idealized complete contracts. The objectives of the pape...

In this paper we consider source-initiated multicast session traffic in an ad hoc wireless network, operating under hard constraints on the available transmission energy as well as on bandwidth and transceiver resources. We describe the similarities and differences between energy-limited and energy-efficient communications, and we illustrate the impact of these overlapping (and sometimes confli...

Introduction Health system responses to the emergence of non-communicable diseases (NCDs) in many Southeast Asian nations, Cambodia included, have been insufficient. Little is known about how people suffering from such conditions behave in constrained contexts. We examined the experience of patients with NCDs as they seek care for their conditions and manage them. Methods In-depth interviews ...
