Introduction to differential equations
Differential equations are any equations that include derivatives and arise in many situations. This free course, Introduction to differential equations, considers three types of first-order differential equations. Section 1 introduces equations that can be solved by direct integration and section 2 the method of separation of variables. Section 3 looks at applications of differential equations for solving real world problems. Section 4 introduces the integrating factor method for solving linear
1.3.10 Summary There is a lot of information available on Modern Languages via the internet. Try the activity below to start exploring what is available. Use the Author(s): 2.2.2 Collimator The dimensions of the emerging X-ray beam can be altered by the collimator. This helps to ensure that only the region of interest is exposed to the X-rays. Understanding Cities 6.1.3 Ensuring safety Ensuring that a user can't choose a wash temperature that's too hot for the ‘hand wash’ programme is an example of ensuring safety. In other words, the washing machine microcomputer is trying to prevent the user making choices that are not sensible. Of course, I could put a load of delicate washing in and choose the ‘cotton’ programme which has a temperature of 90°C. The computer program controlling the machine has no way of knowing that I've put silks or woollens in and not c 2.5 Clusters A striking contradiction of the internet revolution is that, although cyberspace allows firms to be located anywhere, they still seem to cluster together in global cities such as New York, London and Sydney (Castells, 2001). Four years after publishing a book proclaiming The Death of Distance, Frances Cairncross noted in the book's second edition that, ‘Economists, most of whom have long ignored or despised economic geography, are now taking a fresh interest in it’ and, after revie Sea Urchin Development 4.4.1 Diversion of effluent In some circumstances it may be possible to divert sewage effluent away from a water body in order to reduce nutrient loads. This was achieved at Lake Washington, near Seattle, USA, which is close to the sea. Lake Washington is surrounded by Seattle and its suburbs, and in 1955 a cyanobacterium, Oscitilloria rubescens, became dominant in the lake. The lake was receiving sewage effluent from about 70 000 people; this input represented about 56% of the total phosphorus load to the lake. NSIPP: North America Water Vapor and Soil Moisture Celebrating 15 Years of Metamaterials 2.5 Summary of Section 1 England, Scotland and Wales are nations. Wales was conquered by the English in 1282 and its parliamentary union with England took place in 1536. The United Kingdom of Great Britain was formed by the Act of Union of 1707, although the term Great Britain had been in use since 1603, when James VI of Scotland became James I of England (including Wales). Later unions created the United Kingdom of Great Britain and Ireland and, 4.2.3 Lens system The function of the lens system is to project an image onto the CCD light sensor. A well-designed system ensures that the image is sharp – in focus – and bright. To achieve this, what is needed is a good-quality glass lens (or rather a series of lenses) and accurate focusing. The brightness of the image depends upon the size of the lens. The bigger the lens, the brighter the image, but bigger lenses are more difficult to make and therefore more expensive. Also, of course, bigger lenses me 4.1 PROMPT There is so much information available on the internet on every topic imaginable. But how do you know if it is any good? And if you find a lot more information than you really need, how do you decide what to keep and who to discard? In this section we are going to introduce a simple checklist to help you to judge the quality of the information you find. Before we do this, spend a few minutes thinking about what is meant by information quality.

Many people attend day care services and find that the change is a stimulating experience, widening their daily contacts and allowing them to become part of another group. The issues of continuity of experience raised here will be familiar to day care workers. Click below to hear an audio clip describing Redwood Day Unit.

Attempting to pass off someone else's work as your own is plagiarism.
You may be encouraged to use the Web as a resource for writing assignments. This does not mean you should copy chunks of text from other websites however. You can quote from other sites, but such quotes should always be acknowledged. You should write material in your own words, to demonstrate that you have understood it, rather than simply copying it. Using search engines it is relatively easy for markers to

In 15 years metamaterials has brought breakthroughs like invisibility cloaks, acoustic cloaks, miniaturized flat antennas, and you-don’t-have-to-stop-anymore airport security screenings. Watch as two of the field’s founding fathers reminisce about their journey and look forward to the future. Metamaterials pioneers David R. Smith of Duke University’s Center for Metamaterials and Integrated Plasmonics and Sir John Pendry of Imperial College London discuss the birth, evolution and future of
A new energy harvesting system developed at Vanderbilt University can generate electrical current from the full range of human motions and is thin enough to embed in clothing.
Here is an animation of General Henry Knox talking about his life as a general working with Washington. Strange presentation, but useful in presenting a picture of what Know did during the Revolutionary War.
6.336J is an introduction to computational techniques for the simulation of a large variety of engineering and physical systems. Applications are drawn from aerospace, mechanical, electrical, chemical and biological engineering, and materials science. Topics include: mathematical formulations; network problems; sparse direct and iterative matrix solution techniques; Newton methods for nonlinear problems; discretization methods for ordinary, time-periodic and partial differential equations, fast
