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. Sometimes, despite the best preparation, the only thing they can rely on for protection is their vehicle. In collaboration with the United States Army, Notre Dame Engineering Professor John Renaud is working to address one of the most threatening causes of injury and harm in the field today - improvised explosive devices. His team's work focuses on ways to improve the

Open-Ended Research Questions: Success Secret for Research Projects
How to frame an open-ended research question for your research project: who, what, when, where, why, how--and all the variations of them.
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
Changing the Face of American Healthcare
Notre Dame OpenCourseware (OCW) offers free educational resources for the course "Changing the Face of American Healthcare" in the Center for Social Concerns. This seminar invites the student to learn about the strengths and weaknesses of our health care system, explore possibilities for the future of American health care, and to consider how modifications might help create the society we hope to become.
Il linguaggio come strumento della mente. In che senso l’apprendimento precede lo sviluppo. (terza
Come ha inizio la mente. L’interazione sociale è processo di apprendimento che precede lo sviluppo: l’influsso di Vygotskji. Il linguaggio come strumento della mente. In che senso secondo Bruner l’apprendimento precede lo sviluppo.,Language seen as a mind instrument. In what sens learning comes before the development.(Third lesson)How mind gets started. Social interaction is a learning process that comes before the development: Vygotskji's influence. Language seen as a mind instrument. In
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
New concepts in bridge research, testing and safety
Civil engineers at Oregon State University have developed a new system to better analyze the connections that hold major bridge members together, which may improve public safety, help address a trillion-dollar concern about aging infrastructure around the world, and save lives.

The Native American Ten Commandments
The Native American Ten Commandments include love of nature, respect, peace, knowledge, and justice. Done with words and pictures, these Commandments are a good starting place for an understanding of how some tribes worshipped and lived in harmony with the wolves and other animals (Running Time 3:57).
