8 Conclusions

In this course you have learned about the difference between the analogue world we inhabit and the digital world of the computer.

I've described how features of our world can ‘cross the boundary’ and be represented or modelled in the digital world, and then brought back across the boundary to us.

More excitingly, computer programs that manipulate digital representations of our world enable us to:

5.3 Neighbourhoods

We know that a polygon X is a surface and so each point x in X has a disc-like or half-disc-like neighbourhood. We shall show that a map f that identifies edges of a polygon to create an object Y automatically creates corresponding disc-like or half-disc-like neighbourhoods of each point y = f(x) of Y.

If x is in the interior of X, there is no difficulty: the point x has a disc-like neighbourhood U

5.9 Membrane filtration

Membrane filtration is a process whereby particles smaller than about 10−2 mm (which can pass through sand filters) are removed using synthetic polymeric membranes and a high pressure. The membrane effectively acts as a sieve.

It is increasingly becoming popular as an advanced treatment process for water (especially for removal of Cryptosporidium) and wastewater (where water reuse takes place), and various possibilities are:

2.4 Analysing Hansa's essay

To refresh your memory, look again at Hansa's essay and the notes you made earlier. The first thing I noticed is that her essay starts with the title she was set. It also comes to a conclusion that tries to answer the question in the title, so straight away it has some important strengths compared to Philip's. From the start she gets stuck into the argument, making a purposeful attack on the question in her opening sentences. And, while she covers a lot of the same ground as Philip, she devel

9.7 Evaluating strategy and presenting outcomes

Evaluation should focus on both the outcomes of the work and the process. Two critical questions guide evaluation: ‘Did we accomplish our goals?’ and ‘Did we accomplish them in an effective and efficient way?’ Your evaluation should attempt to provide answers to both. Thus you need to know how to:
