...systems are constructed? Did you know that they underpin the majority of the managed data storage in computer systems? This free course, The database development life cycle, has been designed to give you an overview of the developmental lifecycle for a database system, explaining the importance of data analysis and highlighting how database development differs from...

...systems are examples of web applications. Web services describes a standardised way of integrating web applications using the internet standards and protocols. This OpenLearn course is an adapted extract from the Open University course TT284 Web Technologies...An introduction to web applications architecture: Learning outcomes - After studying this course you should be...

...systems Are there any bioenergy systems you can think of that could allay the above concerns? Answer Some bioenergy systems, such as short rotation forestry or coppice, can increase biodiversity compared to conventional agriculture. Among more experimental technologies, microalgæ don’t take up agricultural land and may be useful in cleaning up both nutrient residues...

...think of most often when we think of an innovation. Process innovation – a new or significantly improved production or delivery method. Innovations in the way things are made can critically effect, for example, how widely accessible they are. Marketing innovation – a new marketing method involving significant changes in product design or packaging, product placement,...

...systems pervade everything we do; review some basic ideas of signal processing, control and communications; and allow you to use a digital filter to remove Gaussian noise from a signal...Electronics is fundamental to modern life. Take for example this free course, Electronic applications. An interactive website with videos and interactive software will show how electronic...

...system. What information about an image might be useful to astronomers when exchanging images? Think about all the things that you specify when requesting an image. As well as the raw data, it would be useful to know the celestial coordinates, the date and time that the image was taken, the exposure time, and what filter was used. For this reason, astronomers use an...

...systems. Finite element analysis (FEA) is an indispensable software tool in engineering design, and indeed in many other fields of science and technology. In this course you will be introduced to the essence of FEA; what is it and why do we carry out FEA? As an example of its use, we will look briefly at the case of finite element analysis of the tub of a racing car....

...think it's a fascinating story because the climate is a complex system, and it's a difficult thing to understand. Climate models are getting more and more complicated as we understand them better, and we put more, and more science into the code, and they're getting better at reproducing the climate. But there's always going to be some things that we can do better, and...
