Shape Grammars for Innovative Hybrid Typological Design
This paper describes a new methodology of deriving innovative hybrid designs using shape grammars of heterogeneous designs. The method is detailed within three phases of shape grammars: analysis, synthesis and evaluation. In the analysis phase, the research suggests that original rules of each design component are grouped in subclass rule sets to facilitate rule choices. Additionally, adding new hybrid rules to original rules expands the options available to the grammar user. In the synthesis ph
An Interactive Shape Modeling System for Robust Design of Functional 3D Shapes
In Architecture, it is essential to design functional and topologically complicated 3D shapes (i.e. shapes with many holes, columns and handles). In this paper, we present a robust and interactive system for the design of functional and topologically complicated 3D shapes. Users of our system can easily change topology (i.e. they can create and delete holes and handles, connect and disconnect surfaces). Our system also provide smoothing operations (subdivision schemes) to create smooth surfaces.
Thin section of ZnO varistor
The micrograph shows structure of ZnO, containing small amounts of oxides such as Sb2O3 and Bi2O3. Thin section was produced using liquid phase sintering: gives rise to a structure consisting of conductive ZnO grains with the additional oxides being preferentially located at grain boundaries. A varistor is used to short-circuit transient high voltage spikes in electronic devices. Incorporated into circuits, in parallel with the device to be protected. Acts as an insulator below a certain breakdo
Carbon-carbon composite
The micrograph shows structure of a carbon-carbon composite, 40 microns
What Happened to Collaborative Design?
In this paper we present the results of a comprehensive literature survey on the development of collaborative design. We reviewed 324 papers on collaborative design, taken from various sources (conferences, journals, and PhD-theses). We grouped the papers based on common themes, and in that way derived a classification of themes through the last 25 years (1983-2008). Each category is described, its development, and key publications are identified.
Roll-bonded aluminium alloy diffusion couple in the as-rolled condition.
This micrograph shows the grain structure of a roll-bonded aluminium alloy diffusion couple in the as-rolled condition. The upper half of the couple is Al-0.5Fe-1.0Mn (wt.%), the lower half is Al-1.0Si (wt.%). Rolling heavily deforms the microstructure, producing thin, elongated grains parallel to the roll-bonded interface.The Barker's etch produces a thick oxide layer on the grains of aluminium (anodising). When viewed in cross-polarised light, interference in the oxide layer produces colours w
Ni-hard iron
This is a Ni-hard iron, one of the first cast irons to be developed. These white irons contain Ni to ensure that the austenite transforms to martensite following heating and chromium to increase the hardness of the eutectic carbide.Ni-hard irons are normally stress relieved at 200-300 °C for approximately four hours to relieve the martensitic transformation stresses and to promote the transformation of retained austenite. The structure consists of proeutectic austenite dendrites containing mart
Fe, C 0.2 (wt%), explosively deformed - mechanical twins
This sample was explosively deformed so that there was insufficient time for dislocation motion to occur. Hence, mechanical twins are produced despite the b.c.c. structure of mild steel.
Unhinged!
Sometimes you can tell what a structure does just by looking at it. The environment plays a critical role in shaping the evolutionary changes that organisms undergo. For animals, food is one of the most important components of the environment. This video focuses on snakes and some of the most important adaptations of these remarkable creatures. Video addresses teeth structure, skull structure, and other clues of structure and function provided for individual adaptations. Closed captioning. R

As taught in Autumn Semester 2009/10
The War on Iraq and the US and British invasion of the country in 2003 has led to huge tensions in geopolitics. At the same time, the supposed ‘threat’ of international terrorism and continuing financial turmoil in the world economy have both brought to the fore the global politics of co-operation and confrontation. Whilst it might be possible to agree on the significance of
Optimal Financial Structure and Economic Development
The Optimal Financial Structure of a specific stage of development in an economy is determined by the structures of industries and firm sizes in the economy. These, in turn, are determined by the economy's factor endowments at that stage. This lecture will discuss the existence on an endogenously determined optimal composition of various financial arrangements, that is, optimal financial structure, for an economy at different stages of development.
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction.
It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status.
This system is widely used
Conservation and biodiversity
Dr. Richard Field research interests lie in conservation, biodiversity and the forces that structure ecological communities.
In this podcast, Dr Field from the School of Geography compares and contrasts his experiences as a researcher in national parks in Honduras and Indonesia, and the different types of ecological communities he has studied, and goes on to introduce the emerging field of conservation bio-geography.
14.15J Networks (MIT)
Networks are ubiquitous in our modern society. The World Wide Web that links us to and enables information flows with the rest of the world is the most visible example. It is, however, only one of many networks within which we are situated. Our social life is organized around networks of friends and colleagues. These networks determine our information, influence our opinions, and shape our political attitudes. They also link us, often through important but weak ties, to everybody else in the Uni
Cell-O
Developed for third and fourth grade. In this activity students will be able to explore the structure of a cell by building their own models with Jell-o and candy. Students will learn the different parts of the cell and their functions. We will also discuss the importance of cells in the human body.

Modeling the interior of the Earth using Seismic Waves
This is an inquiry-based student exercise designed to explore how we use seismic waves to understand the structure of the Earth's interior. Students test several models of the interior of the Earth beginning with a simple homogeneous Earth and moving toward more complex multi-layered Earth models. The ultimate goal involves student generation of a model that reproduces actual measured seismic travel times as closely as possible. The activity is appropriate for an introductory level geoscience co
Patricia Johnston Sings "I See the Sun"
This beautifully done video sings about the sun, moon, stars, ...Some of the lyrics include "I see the sun-a big round sun. I see the moon-a big round moon. I see the stars-the little, little stars---smiling just for me". These videos by Patricia Johnston were designed for young French children to begin to learn English. This is a great teaching resource for early childhood learners and/or special education students and would work well in conjunction with a unit on Earth and to help build backgr
