1 Technological change, demand and costs

The new economy

Over the past 40 years global computing power has increased a billionfold. Number-crunching tasks that once took a week can now be done in seconds. Today a Ford Taurus car contains more computing power than the multimillion-dollar mainframe computers used in the Apollo space programme. Cheaper processing allows computers to be used for more and more purposes. In 19

20.104J Chemicals in the Environment: Toxicology and Public Health (BE.104J) (MIT)
This course addresses the challenges of defining a relationship between exposure to environmental chemicals and human disease. Course topics include epidemiological approaches to understanding disease causation; biostatistical methods; evaluation of human exposure to chemicals, and their internal distribution, metabolism, reactions with cellular components, and biological effects; and qualitative and quantitative health risk assessment methods used in the U.S. as bases for regulatory decision-ma

1.2 Disentangling sounds

If you are still feeling aggrieved about the shortcomings of evolution, then you might take heart from the remarkable way in which the auditory system has evolved so as to avoid a serious potential problem. Unlike our eyes, our ears cannot be directed so as to avoid registering material that we wish to ignore; whatever sounds are present in the environment, we must inevitably be exposed to them. In a busy setting such as a party we are swamped by simultaneous sounds – people in different pa

Abstract Styles in the Vienna Workshop: A Formalist Analysis of Josef Hoffman?s Two Designs
A shape grammar formalism is elaborated for the Vienna Workshop (Wiener Werkstaette) designer Josef Hoffmann?s two designs. Early instances of abstract expressionism are traced in Hoffman?s works by investigating stylistic parallels through shape rules and computations. The analysis of Hoffmann?s two works are carried out in parallel to Terry Knight?s analysis of De Stijl artists Georges Vantongerloo and Fritz Glarner paintings with the normal form grammars.

Introduction

This course provides an introduction to global warming. We will be considering the history of global warming by looking at the pattern of ice ages and analysis of recorded temperatures. We will aim to gather meaningful information from this data. We will briefly assess the impact and influence of humans on global warming and, finally, we will examine climate models and how to predict future changes.

This OpenLearn course provides a sample of postgraduate study in Author(s): The Open University

The Art of Computer Graphics Programming: Translating Pioneer Programs
Considering the importance of the use of programming languages for teaching computational design to architects, this paper proposes the translation of computer programs from a pioneer work in this field into a more contemporary programming language. The book The Art of Computer Graphics Programming: A Structured Introduction for Architects and Designers was published in 1987 by William J. Mitchell, Robin Ligget and Thomas Kvan, and remains an important reference for architects. The original Pasc

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

Dérivation des équations de Saint-Venant (Ondes de surface et ressauts)
Ce cours détaille la dérivation des équations de Saint-Venant à partir des équations de Navier-Stokes incompressibles à surface libre sur un pan incliné. Cette dérivation repose sur l'existence d'un petit paramètre représentant le rapport entre les échelles verticales et horizontales. En maintenant le nombre de Froude d'ordre 1, on examine plusieurs limites en fonction de l'ordre de grandeur du nombre de Reynolds et de la pente du fond. Suivant les cas, on obtient l'approximation des

3.5.5 Biological indicators

A great many biological species and individuals occur in normal streams. These often differ markedly in their sensitivity to environmental factors, and likewise the tolerances of various species to different types of pollution vary considerably. The major groups of organisms that have been used as indicators of environmental pollution include bacteria, fungi, protozoa, algae, higher plants, macroinvertebrates and fish. The benthic 'bottom living' macroinvertebrates are particularly suitable a
