visceral leishmaniasis is a deadly parasitic disease that is transmitted via the bite of a female sand fly, phlebotomus argentipes. the highest burden of this disease is in northern india. in 2005, india embarked on an initiative with ne­pal, bangladesh, and the world health organization to eliminate visceral leishmaniasis by 2015. with the goal of 1 case in 10,000 people still unmet, it is pru...

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
