Models and simulations of blood flow in vascular networks are useful to deepen knowledge of cardiovascular diseases. This paper considers a model based on partial differential equations that mimic the dynamics of vascular networks in terms of flow ve

We analyse a cell of Cognitive Radio Network ( $CRN$ ) as the multiline queueing system supplying service to two Markovian arrival flows of users. Primary (or licensed) users called as High Priority Users ( $HPU\text{s}$ ) have a preemptive priority

A queuing system having two different servers is under study. Demands enter the system according to a Markov arrival process. Service times have phase-type distribution. Service of demands is possible only if the fixed number of energy units, probabl

A single-server retrial queue with a MAP flow, PH service times and a pool of finite capacity for accumulation of the customers and their group service is considered. Service to the next group is not provided until the number of customers in the pool

This paper is devoted to the construction of multivalue mixed collocation methods suitable for ordinary differential systems whose solution is known in advance to be oscillatory. Theoretical results concerning the construction and the accuracy of the

We consider a 1D model for the simulation of the cardiovascular system. We solve it numerically using the discontinuous Galerkin scheme, and we perform an optimization scenario to find the best value for the heart rate in order to obtain a desired ou

A family of multivalue collocation methods for the numerical solution of differen- tial problems is proposed. These methods are developed in order to be suitable for the solu- tion of stiff problems, since they are highly stable and do not suffer fro

The paper is focused on the development of A-stable collocation based multivalue methods for stiff problems. This methods are dense output extensions of discrete multivalue methods, since the solution is approximated by a piecewise collocation polyno

This paper focuses on a supply network, that deals with wine production, that is typical of Southern Italy. Such a phenomenon is analyzed by differential equations, that model goods on arcs and queues for the exceeding parts. Various numerical scheme
