Introduction

There is more to computers and processors than simply PCs. In fact computers are ubiquitous in everyday life. This unit challenges how we view computers through the examples of processors in kitchen scales and digital cameras, as well as a work of art that, at heart, is a computer.

This unit is from our archive and is an adapted extract from Computers and processors (T224) which is no longer taught by The Open University. If you want to study formally with us, you may wish to explore ot

3 The purpose of writing

Let's take a step back and think about why you are writing assignments. As with most tasks, if you have an understanding of why you are doing something and how it fits into the bigger picture, it is easier to define what is required of you and therefore to do a good job.

So, what do you see as the reasons for writing assignments? Here are some suggestions:

  • to meet the assessment requirements of my course;

  • to demonstrate my understa

12.1 Localisation of sound in the horizontal plane

While information about frequency and intensity is essential for interpreting sounds in our environment, sound localisation can be of critical importance for survival. For example, if you carelessly cross the street, your localisation of a car's horn may be all that saves you. Our current understanding of the mechanisms underlying sound localisation suggests that we use different techniques for locating sources in the horizontal plane and vertical plane.

1 Putting the unit in context

This course, taken from T883 Business operations: delivering value, is concerned with the management of ‘processes’ – the organised set of resources and related activities that are essential for the delivery of goods and/or services to customers. These processes or ‘operations’ form the very essence of any enterprise, and it is critically important that they are managed well to be effective and efficient.

The full course consists of three main blocks of study:

2.3 Common maths problems and errors in the workplace

In a busy, hospital environment mistakes with medicines and other treatments can happen at any time. Some of these are caused by communication/administrative problems, whilst others are due to mathematical errors (the news stories shown in Figure 7 are sadly typical).

Simplifying Cube Roots
Students learn to simplify a square root by setting up a factor tree for the number inside the radical. If a factor pairs up in the factor tree, then it comes out of the radical. If a factor does not pair up, then it stays inside. Students also learn to simplify a cube root by setting up a factor tree for the number inside the radical. If a factor is part of a group of three factors that are the same, then it comes out of the radical. If a factor is not part of a group of three factors that are

6.2 Preparing and drafting a Bill

A period of preparation of a Bill allows time to scrutinise evidence on the policies underlying Bills, and to consider whether Bills can be improved before they are introduced. Proper preparation of a Bill should lead to better-informed debates on Bills when they are introduced, and may save time by identifying problems at an early stage. This period of pre-legislative scrutiny allows valuable time for consideration, and therefore helps to avoid introducing laws that are unworkable. Consultat

8.1 Why polish?

Once you have reached this stage, you have nearly finished.

What does polishing mean, and what does it involve? Imagine polishing a car or a piece of furniture. Why might you do so? Usually, to make it look better, to present it in the best possible light, either for your own pleasure, or to impress others – perhaps because you want to sell it. If it is an object that you value, it is worth making it look its very best: it deserves it. How effective your polishing is usually depends o

#374: Not merely emotion: Reclaiming "passion" as a driver of human behavior

Philosopher of the emotions Prof Louis Charland argues that we need to reinstate the notion of "passion" in our understanding of human behaviour. Now little mentioned outside of the arts and self-help domains, passion has deep historical roots and may have important contemporary use as a lens through which to view certain psychiatric conditions

6.4.1 Materials selection

Among the common thermoplastics available in the mid-1970s, polypropylene appeared as a front runner on grounds of toughness, density and cost Table 9). However, it is subject to creep (being uncrosslinked) and possesses a low tensile modulus of ca. 1500 MN m−2. Its merit index is 12.7 due to the low density of 0.

4.4 Representing sound

Sound, such as speech or music, is an analogue physical quantity that varies with time, and so the ideas you have already met in Section 2.5 about converting analogue weights to digital form are relevant here too. In particular, samples of the sound will have to be taken, and each sample will have to be quantised to the nearest binary code in the digital representation.

It's important to appreciate that sound such as speech or music varies rapidly with time, and so samples of it will ha
