The present document defines objectives, programme and expected learning outcomes for all the above mentioned courses. Nature is by far the best Engineer worldwide and the human body is the living evidence of this statement: the dynamic interplay among skeleton, thought, breath, motion, muscles, and cardiovascular flow, is the driving force to everyday's life and a continuous inspiration for the design and development of novel materials and devices. Leveraging this unexpected connection between Life Sciences and Electronic and Biomedical Engineering, the course of Computational Modeling in Electronics and Biomathematics (CMEBM) aims at providing the student the basic instruments to construct a mathematical model of a realistic problem and the theoretical tools to develop and analyze methods and algorithms for its stable and accurate solution on a computer machine. Electronic and biological systems share significant structural similarities. Transmembrane ion flow regulating the functional response of a neuronal or cardiac cell, as well as the motion of electric charge transporting current in a nanoscale-sized transistor, obey the same phenomenological description, well known in Biology as the Nernst-Planck model and in Electronics as the Drift-Diffusion model. The goal of the course is threefold and consists of providing the students:

  1. a unified framework for the mathematical modeling of:

             1.a: cellular biology and

             1.b: solid-state electronics;

  1. the numerical methods for the simulation of:

             2.a: specific cellular systems and

             2.b: specific electronic devices;

  1. a critical know-how to perform the design of complex systems in:

             3.a: Life Sciences and

             3.b: Electronics.

For students of the course coded 050492: goals 1.a, 2.a and 3.a.

For students of the course coded 096660: goals 1.b, 2.b and 3.b.


Risultati di apprendimento attesi

Class lectures and laboratories:

  1. will provide students the theoretical foundations of models and numerical methods;

  2. will allow students to verify in a quantitative manner the physical accuracy of the models and the numerical performance of the methods through the solution of exercises of increasing level of difficulty;

  3. will enable students to gain acquaintance with the critical analysis and design of a complex system in Life Sciences and Electronics through the combined use of theoretical modeling tools and a flexible computational environment such as Matlab.

The theoretical concepts, methods and algorithms will be numerically verified during the laboratory sessions through the solution of exercises and the critical discussion of project assignments. Exercise solution and project discussion will be conducted with the interactive participation (through remote web connection) of Prof. Giovanna Guidoboni, University of Missouri, Columbia MO, USA, a worldwide expert in the development and analysis of fluid-mechanical computational models in Ophthalmology and Fluid Flow in the Cardiovascular and Lymphatic systems. Projects will be subject to evaluation and will contribute to determine the final grade of the student.

Modalità di valutazione

Student evaluation is the result of two contributions, the sum of which yields the final grade:

1. The first contribution is provided by the evaluation of a number of project assignments that must be elaborated by each student during the laboratories. Each project assignment will have a minimum grade of 0/30 and a maximum grade of 2/30, for a total of 10/30.

2. The second contribution is provided by the evaluation of a written test. Five exam sessions that will be scheduled according to the dates established by the calendar of the School of Industrial and Information Engineering. The written test consists of the solution of a number of exercises pertaining to the three main topics treated during classes and laboratories, namely: Elements of Numerical Approximation of Balance Laws in Local Form, Elements of Cellular Biology and Elements of Solid-State Electronics, and is organized according to the following structure:

a) theoretical questions on the topics covered during the course, including:
statement and/or proof of a theorem or mathematical property of a method; definition of concepts such as convergence, consistency, stability of a numerical scheme; formulation and analysis of a numerical method;
b) computational questions to be numerically solved through the use of built-in MATLAB functions and MATLAB functions implemented during the
laboratories, including: systems of linear equations, interpolation of data and functions, nonlinear equations, numerical integration and differentiation, approximation of ordinary and partial differential equations.

The written test will have a minimum grade of 0/30 and a maximum grade of 24/30. The evaluation process will take into account the correctness and the accuracy of the provided answers, the level of critical analysis of the obtained results, the ability in the use of MATLAB functions to solve basic mathematical problems as well as problems of interest in the engineering practice.
