New strategies for cholera control

Dynamical analysis and control strategies in modeling cholera

We conduct rigorous stability analysis for the well-known cholera model proposed by Codeço [7]. Using theory of monotone dynamical systems, we prove that the endemic equilibrium, when it exists, of the model is globally asymptotically stable, implying the persistence of the disease in the absence of interventions. We then modify Codeço’s model by incorporating various control strategies, and st...

Modeling optimal intervention strategies for cholera.

While cholera has been a recognized disease for two centuries, there is no strategy for its effective control. We formulate a mathematical model to include essential components such as a hyperinfectious, short-lived bacterial state, a separate class for mild human infections, and waning disease immunity. A new result quantifies contributions to the basic reproductive number from multiple infect...

New control strategies for neuroprosthetic systems.

The availability of techniques to artificially excite paralyzed muscles opens enormous potential for restoring both upper and lower extremity movements with neuroprostheses. Neuroprostheses must stimulate muscle, and control and regulate the artificial movements produced. Control methods to accomplish these tasks include feedforward (open-loop), feedback, and adaptive control. Feedforward contr...

New control strategies and user interfaces for train traffic control

The developing situation with higher speed, more frequent traffic, and many competing train traffic operators, requires new principles and technical solutions for more efficient train traffic control. Control actions are today often mainly focused on controlling the technical parts of the infrastructure, signals etc. We have tried to shift the control paradigm from today's more technology orien...
