Molecular Bioengineering (MEng)
Mathematics and Engineering 2
The aims of this modules are to:
Ensure that all students acquire the mathematical knowledge and skills required for the second and later years of their Molecular Engineering programme.
Introduce the principles of signals and control as required for further courses in the Molecular Bioengineering degree.
Provide practice in solving mathematical, signals and control problems posed in a Bioengineering context.
Upon successful completion of this module, you will be able to:
1) Differentiate functions of two or more variables, evaluate simple line, double and volume integrals and carry out changes of variable in multiple integrals.
2) Define and calculate the vector operators grad, div and curl, and state Green's, Gauss' and Stokes' theorems involving those operators.
3) Derive and classify partial differential equations, recognizing the importance of boundary conditions and apply standard methods to solve and verify the solutions of such equations
4) Explain and use concepts related to matrices including: linear transformations performed by a matrix, the significance of eigenvectors and eigenvalues of matrices, eigendecomposition and diagonalisation
5) Describe and apply simple methods for numerical integration.
6) Explain applications of signal processing and control systems in biomedical engineering - this includes in imaging techniques, and describing physiological signals.
7) Model or represent a signal and/or control system using either mathematical expressions or simulations in Matlab, or an equivalent programming language.
8) Analyse signals quantitatively and with the use of computational methods.
In this module you will cover the following topics:
VECTOR CALCULUS: parameterised curves; scalar and vector fields; grad, div and curl; arc length; line integrals; conservative fields; double and triple integrals; Green`s theorem in the plane; surface integration; Gauss` and Stokes` theorems.
