4.2 Instantaneous acceleration

The procedure of Question 15 for determining the instantaneous velocity of the car can be carried out for a whole set of different times and the resulting values of vï»¿ï»¿x can be plotted against t to form a graph. This has been done in Figure 28, which shows how the velocity varies with time. At time t = 0 s, the car has zero velocity because it starts from rest. At later times, the velocity is positive because the car moves in the direction of incre

2.1 Overview

The Scottish education system is distinctive and has a long independent history. The courses within this section cover the national curriculum framework in Scotland and give examples of learning in some Scottish schools.

In teachers' professional development, The Open University works with The General Teaching Council for Scotland (the independent regulatory body for the teaching profession in Scotland) to develop courses and qualifications specifically tailored to Scotland's needs, e.g

2.4.3 Polarization mode distortion

Because light is an electromagnetic wave, it has a â€˜state of polarizationâ€™, which, for light in single-mode fibre, is at right angles to the path of the fibre. If you've not encountered electromagnetic waves before, all you need to appreciate is that as light travels down the fibre the electromagnetic field has an orientation across the fibre (Author(s): The Open University

Learning outcomes

After studying this course, you should be able to:

• understand some of the key ways in which globalisation is shaping the world today

• give examples of how ideas of 'proximity' and 'distance' can be used to understand an increasingly demanding world

• illustrate the importance of recognising the liveliness of the natural world.

Diabetes care
At least 171 million people worldwide have diabetes, and this figure is set to double by 2030. This chronic condition, which occurs when the body cannot produce or effectively use the insulin it needs, can be the cause of many serious health complications leading, amongst other problems, to blindness, foot ulcers and kidney failures. This album is a must-watch for diabetes sufferers and medical staff training to work with diabetes patients. Six video tracks introduce various aspects of a patient

1.2.4 What is computing with confidence?

A confident computer user is one who knows more than just the required key presses to operate the software they are using. The two most important qualities of a confident computer user are:

• knowing how to cope when things go wrong;

• knowing how to learn new computing skills independently.

Introduction

This unit introduces the important distinction between our analogue world of colour, sound, taste and touch and the computer's peculiar binary world of digital entities. Concepts of the analogue universe in which we live and the digital world we create are explained. The way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world is explored.

This unit is from our archive and is an adapted extr

7.3 Depositing metals and alloys

Metal layers are used extensively in device fabrication: to carry current for both power and signals, to apply the voltages that control transistors and generate forces for MEMS, as mirrors and optical coatings, and in magnetic devices for recording media. Different applications might require a continuous film, a long track, multiple thin layers or a plug filling a â€˜via holeâ€™ through to a buried layer. The electrical properties resulting from micro structure and composition must be contro

Energy policy and climate change
The 2009 United Nations Climate Change Conference in Copenhagen presents a new focus for international debate and decisions about energy and its use. What are the countries of Western Europe and Scandinavia doing to promote sustainable energy production? Just how different will the future energy map of Europe look? And is energy policy principally a scientific issue or a political one? This album contains a series of films exploring energy policy in various countries around Europe in 2006, frame

1.3.3 Speciality sectors

There are many sectors of the market where polymers have made dramatic inroads, including medical/ethical, leisure and aerospace products. The influence of density as a property is most dramatic in the last area, simply because weight saving on aircraft fuselages creates large savings in fuel usage or, alternatively, means that more passengers and/or freight can be carried per aircraft. Although complete polymeric fuselages are rare, only being used to date in small aircraft (such as the â€˜L

If Fiber is the Medium, What is the Message? Next-Generation Content for Next-Generation Networks
By investigating price and capacity trends over the past century, Eli Noam shows that it is possible to predict the type, style, and genres of media content of a future ultra-broadband infrastructure, which allows a richer, more bit-intensive content. The nature of content is critical for the economic viability of an ultra-broadband infrastructure. This paper asks what types of media content we will have when we achieve widespread fiber optic networks. In the past, an expansion of transmission c
