7.3.4 Physical vapour deposition (PVD), sputtering

An ion hitting a metal surface after acceleration through more than 100 V will not stick or bounce off but will burrow into the surface, splashing atoms outwards. This is known as sputtering and provides a versatile alternative to thermal evaporation for metal-vapour deposition: more controllable, with adjustable uniformity, able to cope with alloys and high-melting-point metals and suitable for production-line automation. Given these advantages, it is also worth the effort to heat the

2.035 Special Topics in Mathematics with Applications: Linear Algebra and the Calculus of Variations
This course forms an introduction to a selection of mathematical topics that are not covered in traditional mechanical engineering curricula, such as differential geometry, integral geometry, discrete computational geometry, graph theory, optimization techniques, calculus of variations and linear algebra. The topics covered in any particular year depend on the interest of the students and instructor. Emphasis is on basic ideas and on applications in mechanical engineering. This year, the subject

6.881 Representation and Modeling for Image Analysis (MIT)
Most algorithms in computer vision and image analysis can be understood in terms of two important components: a representation and a modeling/estimation algorithm. The representation defines what information is important about the objects and is used to describe them. The modeling techniques extract the information from images to instantiate the representation for the particular objects present in the scene. In this seminar, we will discuss popular representations (such as contours, level sets,

3.1 Part B overview

The European Convention on Human Rights was introduced in course W100_4 Europe and the law, and through your previous studies you have probably already considered cases (such as that of Diane Pretty) where articles of the European Convention on Human Rights were under debate. Here you will look at its legal implications in more detail. You will consider how the European Convention on Human Rights came into being, why it was considered necessary to create such an instrument, what are it

2.4 Homeomorphic surfaces

As we stated in Section 1, our aim is to classify surfaces up to homeomorphism. So it is worthwhile spending a little time examining what sorts of transformations of surfaces are homeomorphisms. We shall restrict the description to surfaces in space, as these are easier to deal with, though the result at the end of this subsection applies to all surfaces.

Recall that a homeomorphism between two topological spaces (such as surfaces in space) is a bijection with the property that b

10.34 Numerical Methods Applied to Chemical Engineering (MIT)
This course focuses on the use of modern computational and mathematical techniques in chemical engineering. Starting from a discussion of linear systems as the basic computational unit in scientific computing, methods for solving sets of nonlinear algebraic equations, ordinary differential equations, and differential-algebraic (DAE) systems are presented. Probability theory and its use in physical modeling is covered, as is the statistical analysis of data and parameter estimation. The finite di

2 The role of the governing body

When performance review was first introduced, many governing bodies felt unable to undertake the role with confidence. They felt they were being asked to judge teachers and, particularly, headteachers, and were not comfortable with this.

Although the governing body is responsible for the performance management process in the school, it is not the role of the governing body to monitor the work of individual teachers. This is the task of the headteacher, or other appropriate

5.1 Genetic databases and disease

Section 2 looked at data and information from two different perspectives: that of the individual and that of commercial organisation. The type of data you have will dictate both why you want to process it using a computer and, to a large extent, how that is done.

This section contains two short case studies whose unifying theme is that the computer and its programs are tools for working with data. The two studies provide an interesting contrast between:

5.2.2 Continuous variables

Not all numbers are discrete. Consider the following measurements:

  • temperatures recorded at intervals during a day

  • weight of each bunch of grapes sold at a supermarket yesterday.

Time, temperature and weight are all examples of numerical data, but there is not a restricted set of values that they can take. Whereas you can have 2 or 3 children in a family but not 2.5, with tempe

5.2 Wilberforce’s anti-slavery campaign in context

Certainly the outcome was a positive one from Wilberforce’s point of view in that abolition of the slave trade in British ships and colonial possessions passed rapidly through both Houses of Parliament, and became law in March 1807. This result in part implied an increased receptivity to Wilberforce’s religious arguments against slavery, but there were also other factors at work. These included the advance of liberal ideas of justice and toleration, themselves reflecting the influence of

Section 7 showed that if a reaction is to occur at a particular temperature, two conditions must be fulfilled: its equilibrium constant must be sufficiently large, and its rate sufficiently great. We finish by pointing out how this crucial distinction between the equilibrium constant and the rate reveals itself in Figure 52. The f
