__Numerical Simulation of Distributed Parameter Processes__**Springer Verlag 2013, 340 pages**The monography “Numerical Simulation of Distributed Parameter Processes” defines, interprets and uses the “matrix of partial derivatives of the state vector (Mpdx)” with applications for the study of some common categories of engineering, of the processes with distributed and concentrated parameters. For such processes we mainly pursued the elaboration of a unified and systematic method for:

**-The analogical modeling through (Mpdx);**

**-The numerical simulation through (Mpdx) and Taylor Series.**The book covers broad categories of processes, formed by systems of partial differential equations (PDE), including systems of ordinary differential equations (ODE), analogically modeled and numerically simulated by (Mpdx). The book includes numerous applications specific for the Systems-Theory, based on (Mpdx), such as parallel, serial and with feed-back connections for the processes defined by PDE. For similar more complex processes based on (Mpdx), having PDE and ODE as components, we have developed control schemes with PID effects, for the propagation phenomena, in continuous media (spaces) or discontinuous ones (chemistry, power system, thermoenergetic, metallurgy) or in electro-mechanics (railway – traction) and so on.

**Regarding to the Convergence of the Local-Iterative Linearization Method**The work has a purely engineering nature and it has, as a target audience, extremely diverse applicative fields (propagation phenomena, diffusion, hydrodynamics, electro-mechanics) – where the use of (PDE) and (ODE) is justified – and for which the approximated solutions can assure a good compromise between the theoretical rigor and the relative errors cumulated in acceptable or negligible percentages.
