## Specification

### Pre and co requisites

None.

### Aims

This course aims to provide students with an understanding of, and competence in the use of, mathematical techniques that are relevant to the solution of engineering problems. It will also give students a firm foundation from which to develop solutions to a wider and deeper range of engineering problems that they will encounter throughout their undergraduate engineering programme of study.

### Learning outcomes

On successful completion of this course a student will be able to:

1 Demonstrate an understanding of relevant mathematical concepts

2 Manipulate mathematical expressions and equations appropriate to the level and context

3 Carry out relevant mathematical calculations in the solutions to engineering problems

4 Apply the mathematical techniques to the solution of engineering problems encountered using appropriate mathematical software tools

• Fourier analysis: RF spectrum, communications channels, channel blocking;

• Cryptography: cryptographic algorithms and protocols, key exchange, decryption techniques;

• Probability: dealing with uncertainty in engineering, game theory.

### Teaching and learning activity

Learning and teaching take place through a combination of lectures, tutorials and independent study. The course is presented in the context of engineering challenges that the student is expected to solve with the underpinning material supplied through the tutorial sessions and supplementary material provided through the course online resources. Each topic will be introduced with a ‘problem of the week’ that will be solved using the key mathematical topic(s). The listings in the indicative content are examples of the concepts that need to be covered in the problems posed to the student.

The lecture sessions concentrate on the application of mathematics from an engineering perspective. This can be achieved in a specific engineering subject context, for example mechanics, structural analysis, the use of statistics in data analysis, numbers systems that are used in computer systems, communication and computer network systems, or the use of mathematics in business. These areas of applied mathematics are further reinforced with the appropriate mathematical simulation and/or analysis software tools.

The tutorial sessions concentrate on fundamental mathematical principles in order to provide a firm foundation in the core principles required for an understanding of various mathematic concepts, how to carry out appropriate mathematical calculations, use appropriate mathematical notation and terminology, and then be able to manipulate expressions and equations in a suitable manner. Each fundamental aspect of the topic for each week will be supported through mathematical software tools (e.g. Excel, MATLAB).
