3.3 Dams

To economize on constructional materials and costs, it is desirable to build a dam at a narrow part of a valley so that the dam can be kept as short as possible. The quantity of constructional materials needed to build dams, and their cost, can be enormous. The Aswan High Dam, built during the 1960s, cost £400 million for a 1.2 km dam. Though shorter than the Aswan High Dam, the longest dam in Britain, the Kielder Dam in Northumberland (Author(s): The Open University

Trusted Computing Rants, Regrets and Research
How do we build trustworthy hardware, and how can we use that to increase the trustworthiness of broader distributed computation? Sean presents some things he's learned, some things he wishes he had done differently, and some things he'd still like to do. How do we build trustworthy hardware, and how can we use that to increase the trustworthiness of broader distributed computation?

11.942 Regional Energy-Environmental Economic Modeling (MIT)
This subject is on regional energy-environmental modeling rather than on general energy-environmental policies, but the models should have some policy relevance. We will start with some discussion of green accounting issues; then, we will cover a variety of theoretical and empirical topics related to spatial energy demand and supply, energy forecasts, national and regional energy prices, and environmental implications of regional energy consumption and production. Where feasible, the topics will

1.6 Binding forces in molecular and non-molecular substances - a first look

As we shall see in Section 4, elementary bonding theories imply that materials as different as salt, iodine and aluminium are held together by different types of chemical bond. However, all binding forces between atoms are essentially electrical, and arise from a balance of forces acting between positively charged nuclei and negatively charg

5.2 Studying the materials

This is the period when you will be working on your course materials in preparation for the assignment. This may include working through written or electronic texts, any other associated reading or media components, possibly attending a tutorial, accessing any other information that you need and making notes or records of it. Some courses give you a lot of direct guidance on how to work through the course materials; others present you with a range of options and routes. Some courses, particul

2.1 Industrial revolutions and technological change

In this section I shall look at the way that technological innovations in previous eras, such as the invention of electricity in the early 1900s, radically affected the way society organised production and at how these changes spurred general economic growth. In many instances, the changes were so large that they defined an entire period, just as the rise of information technologies has led some to call the current era the ‘information age’.

The way that technological change can fun

John James Ingalls: Fast Track. . .from Law to Politics
John James Ingalls came to Kansas Territory as a young man. He was raised in Massachusetts and trained as a lawyer. He first settled in Sumner, Atchison County. The letters home to his father in this podcast describe his growing success as a lawyer. He also becomes involved in territorial politics as part of the free state movement. His letters are articulate and humorous. Ingalls became a prominent Kansan, ultimately serving as one of the state's U.S. Senators. The text for this podcast

9.3 Differential sensitivity

Absolute thresholds represent only one type of threshold; one could also ask whether the subject can detect a difference between two stimuli. The threshold for detection of difference is called a difference threshold or difference limen (DL). The difference threshold is a measure of the smallest detectable difference between two stimuli. Basically it answers the psychophysical question: ‘How different must two stimuli (e.g. two weights, two colours, two sounds) b

1.3.1 Systems thinking and concept

Much can be said about systems thinking. However it is worth reiterating some key points here as they are central to understanding the purpose of the diagrams discussed later in this section.

The word system is one that is in regular everyday use. People talk, for example, about ‘the social security system’ and the ‘telephone system’. Gamblers boast about ‘having a system’ for winning at roulette. Young people talk about being ‘against the system’.

2.3 Synchronous and asynchronous message passing

Synchronous message passing involves one entity (usually a client) in the message passing process sending a message and a second entity (usually a server) receiving it, carrying out some processing and then sending back some response which the first entity processes in some way. While the second entity is carrying out the processing the first entity pauses waiting for the response.

In asynchronous message passing each entity in the process does not have to wait for the next part

Enacting European Citizenship (ENACT)
The term 'European citizenship' triggers an immediate association with the European Union, its member states, and people who are citizens of those states. This free course, Enacting European Citizenship (ENACT), develops another way of thinking about European citizenship whereby European citizenship need not be granted by the state, limited to the territory within the EU borders or acted out by people who are already citizens.
