Bifurcation of singular arcs in an optimal control problem for cancer immune system interactions under treatment
A mathematical model for cancer treatment that includes immunological activity is considered as an optimal control problem. In the uncontrolled system there exist both a region of ...

Finite Resolution Dynamics
We develop a new mathematical model for describing a dynamical system at limited resolution (or finite scale), and we give precise meaning to the notion of a dynamical system havi...

Rate of decay of s-numbers
For an operator T ∈ B(X, Y ), we denote by am(T), cm(T), dm(T), and tm(T) its approximation, Gelfand, Kolmogorov, and absolute numbers. We show that, for any infinite dimensiona...

Fingerprint Detection Using Canny Filter and DWT, a New Approach
This paper proposes two new methods to detect the fingerprints of different persons based on one-dimensional and two-dimensional discrete wavelet transformations (DWTs). Recent lit...

Quasistatic evolution for Cam-Clay plasticity: The spatially homogeneous case
We study the spatially uniform case of the problem of quasistatic evolution in small strain nonassociative elastoplasticity (Cam-Clay model). Through the introdution of a viscous a...
