Graphical representation of complex eigenvectors
The Graphical representation of complex eigenvectors simulation aims to help students make connections between graphical and mathematical representations of complex eigenvectors and eigenvalues. The simulation depicts two components of a complex vector in the complex plane, and the same vector under several transformations that can be chosen by the user. A slider allows students to change the second component of the initial vector. The simulation shows whether or not the vector is an eigenvector

Regime Uncertainty: Some Clarifications

Private investment is the most important driver of economic progress. Entrepreneurs need new structures, equipment, and software to produce new products, to produce existing products at lower cost, and to make use of new technology that requires embodiment in machinery, plant layouts, and other aspects of the existing capital stock. When the rate of private investment declines, the ra

Autonomous mechanisms in architectural design systems
The development of architectural design systems that describe fully the form, structure and behaviour of a design relies heavily on the incorporation of intelligence in the representations, analyses, transformations and transactions used by the computer. Traditionally such intelligence takes either of two forms. The first is a methodical framework that guides actions supported by the design system (usually in a top-down fashion). The second is local, intelligence mechanisms that resolve discrete

Colloquium Week 7: "What are the social work types and why should we care?"
A paper presented on Tuesday 9th June 2009 at the St Cross College Colloquium. Recent literature and policy movements in the UK and USA have given a great deal of focus to evidence-based practice (EBP) in social services, however there remains little clarity in the literature as to the realities of what these concepts look like in practice. As educational models in the social sciences and policy pressure on human services continue to develop, it is imperative to examine what is being considered

You have now seen how to find squares of whole numbers and decimals. What about fractions? The rule is as before: to square a fraction, just multiply it by itself.

1.4 Offshore fragments of industry: the negative standpoint

Nike Inc., the US sportswear firm, did in fact take the lead in organising its overseas manufacturing business on a subcontracting basis (Donaghu and Barff, 1990). Early on in the 1970s, it established a web of contractual relationships (or partnerships, as it preferred to call them), with factories in Taiwan and South Korea, to produce its branded footwear. Of these factories, the big-volume producers among them were also contracted to other Western firms to produce a range of footwear. Nike

2.4 Summary of Section 2

  • Thermometers sense temperature. They are transducers providing observable and quantifiable signals in variables other than temperature. Thermometers are calibrated to give numbers in accord with an internationally agreed scale. Various attributes influence the selection of an instrument for a task.

  • Temperature can determine the rate at which certain physical and chemical changes proceed, and whether some changes can occur at all.

2.3 Pressure waves and cycles

In this section we shall be looking at the behaviour and properties of pressure waves in the atmosphere.

Sound originates from the motion or vibration of an object. Let's look at an example of a sound wave generated by a vibrating tuning fork. The prongs of the tuning fork move backwards and forwards cyclically. A cycle is a complete series of movements up to the point where the movement starts to repeat itself. As the prongs of the fork vibrate back and forth they push on neighbouring

Initially, I would like you to notice whether and how your appreciation of the phrase ‘managing complexity’ has changed since you started the unit. As you work through Section 4 you will encounter a number of ways of thinking about complexity that may be new to you, so it becomes important to record your developing understanding.
