5.4 Set-up, maintenance and power requirements

Issues for set-up and maintenance include:

  • Cost (what are the costs of setting up and maintaining the technology?)

  • Availability of components (are components readily available?)

  • Interoperability (will devices from different vendors work together?)

  • Continuity of supply (will components still be available for a reasonable period in the future?)

Because of its greater range and complexit

3.23 Electrical, Optical, and Magnetic Properties of Materials (MIT)
This class discusses the origin of electrical, magnetic and optical properties of materials, with a focus on the acquisition of quantum mechanical tools. It begins with an analysis of the properties of materials, presentation of the postulates of quantum mechanics, and close examination of the hydrogen atom, simple molecules and bonds, and the behavior of electrons in solids and energy bands. Introducing the variation principle as a method for the calculation of wavefunctions, the course continu

4.17.1 Software agents

A software agent is a program that displays a certain minimum level of autonomy – it acts as a surrogate for a human user. An agent does something for the user automatically, when given instructions. The more sophisticated the agent is, the fewer instructions it needs, and the more capable it is of making decisions on its own – the more ‘agent-like’ it is. An agent can be run on a client (the user's machine) or on a server (for example, a web server). It can also be anchored (stationa

7.3.2 Evaporation

The simplest vacuum deposition technique is to heat an ingot of metal in a crucible under vacuum, releasing metal vapour that coats everything in its path. This can be done either under high vacuum (< 0.1 mbar), in which case only surfaces in a line of sight from the source will be coated, or in a low-pressure atmosphere, when the vapour is scattered by gas atoms and can go around corners, making batch processing of multiple wafers possible.

This rather simple technique is fast and chea

1 Meet your first active galactic nuclei

Figure 1 compares two nearby spiral galaxies of similar distance and type. NGC 5548, on the left, has a brighter nucleus than that of NGC 3277, on the right. This extra emission from the central regions of NGC 5548 is not generated by stars. Instead this light is thought to be ultimately powered by material falling in the gravitational field of

3.3 Responding to these initiatives

A key implication of both initiatives is greater interagency working, which necessitates more engagement of school staff with other professionals.

The DfES notes in Extended Schools: Providing Opportunities and Services for all that schools will need to work in partnership with other groups and agencies to enable:

  • more diverse activities that involve parents, community members and local groups;

  • a ‘joined-up’ approach
