Science in Focus: Energy: Workshop 7. Heat, Work, and Efficiency
A machine's energy output cannot be greater than its input. In this session, look at the energy that goes into useful work, examine how some always ends up as heat, and see why systems are never 100% efficient.,This segment explores the question "How can we get work from heat?" by visiting classrooms as well as interviewing students and scientists.

1.2 From private trouble to public issue: the emergence of negative equity

In the housing market, owner-occupiers have occasionally sold their property at a price below that which they paid for it. In the early 1990s, large numbers of property owners in the UK (and particularly in south-east England) found that the market value of their houses and flats had fallen below the original purchase price. A private trouble emerged as a public issue. It was named, and became the problem of ‘negative equity’. This was identified as a widespread problem rather than a

24.900 Introduction to Linguistics (MIT)
This class will provide some answers to basic questions about the nature of human language. Throughout the course, we will be learning (in many different ways) that human language is a surprisingly intricate -- yet law-governed and fascinating mental system. In the first 2/3 of the class, we will study some core aspects of this system in detail. In the last part of the class, we will use what we have learned to address a variety of questions, including how children acquire language, ways in whic

Fighting For Those Who Serve
Managing chaos. It's what the men and women in our armed forces have been trained to do every day as they work in combat zones.

Hidden Line Elimination in Projected Grid Surfaces
The hidden line and hidden surface problems are simpler when restricted to special classes of objects. An example is the class of grid surfaces, that is, graphs of bivariate functions represented by their values on a set of grid points. Projected grid surfaces have geometric properties which permit hidden line or hidden surface elimination to be done more easily than in the general case. These properties are discussed in this paper, and an algorithm is given which exploits them

The listening room and stairwell (untitled) within the exhibition Sounding Spaces, ICC, Tokyo
There are two installations in ICC, both in non-gallery spaces, the Lounge area and Stairwell. The basic technology consists of a system of microphone, noise gate, amplifier and speakers in the room, arranged in such a way that when the microphone and loudspeaker begin to feed back the amplitude of the sound causes the noise gate to cut off the signal. The feedback notes resonate through the space accentuated by the reverberation time of the space. As the sound falls below the threshold of t

Rights and justice in international relations
Can the concept of human rights be applied across borders or are rights culturally specific? Is it realistic, or even desirable, to aim at an international system based on universal principles of justice? This unit takes a critical view of the assumption that ‘rights are a good thing’ and looks at the problems that arise when they are applied in the international arena.

Virtual Reality in the Design Studio: The Eindhoven Perspective
Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a numbe
