TALAT Lecture 1102: Environmental Factors
This lecture reviews the environmental factors affecting the aluminium industry and the remedial practices followed; it describes the concept of a product life cycle and the importance of recycling; it also describes the secondary aluminium industry, its history, processes, products and structure; it outlines the methodology used to calculate recycling rates and summarizes the scope and size of the European aluminium industry.
TALAT Lecture 1101: Resources and Production of Aluminium
This lecture illustrates the natural abundance of the element and the history of its extraction from the ore; it shows the properties of pure aluminium, outlines the importance of alloys to commercial development and shows the range of alloys available and their classification; it describes the principal markets for aluminium; it illustrates the basic processes used in the production of primary aluminium and the main fabricating routes used to provide the products needed by manufacturing industr
TALAT Lecture 1100.01: Introduction: Aluminium, a Light Metal
This lecture provides basic information about the history of aluminium, the principles behind the production of primary metal, environmental properties, potential applications, areas of application. The lecture is recommended for those situations, where a brief, general background information about aluminium is needed as an introduction of other subject areas of aluminium application technologies. This lecture is part of the self-contained course "Aluminium in Product Development", which is trea

El Storyboard y el Animatic en la Ense?anza del Proyecto de Arquitectura [Storyboarding and Animatic
This paper discusses the issues involved with the introduction of the storyboard and the animatic in a design studio exercise. Storyboards - sketches used in film planning -, and the animatic - basically a moving storyboard - allow the student to understand space within in the context of a narrative. The purpose of the exercise was to enable the expression of subjectively experienced space in an early stage of urban context analysis. Differently than the traditional approach to animation which r
Inscri??es hipertextuais: a escrita como imagem na cria??o visual contempor?nea [Hypertext inscripti
This paper discusses the creative imagination by the speech?s presence on the contemporary projects of art/design. Nowadays the digital era has shattered limits of the space and the user?s perception in a mix between images and texts, built by numeric language, witnessing possible new ways of writing as image. Considering on the duality between verbal and visual, some post-modern artists/projectors are redeeming the germinal quality of image from the alphabet. They use video and electronic tec
Carbon string
Carbon string is used as a conducting bridge in the preparation of specimens for observation in the scanning electron microscope (SEM). It is also representative of the preforms used in the manufacture of some carbon fibre based composite components. Fibres can be woven into appropriate shapes using traditional weaving technology. The preforms can then be injected with the resin matrix by processes such as resin transfer moulding (RTM) or resin film infusion (RFI).
On the Conceptual Feasibility of a CAAD-CAAI Integrated Decision Support System: A Computer Aided En
This document addresses two questions: What are the ultimate means of design support we can offer to the architect, and how can we devise them? We are not the first ones to address these questions, neither the first ones to point our finger in the direction of Decision Support Systems for such purposes. Nevertheless, we may be among those scholars that understanding 'Decision Support" in terms of "Learning Support", are willing to explore the implications that such an understanding assumes for t
Birefringence in a film of polyethylene
The colours in the image are the result of birefringence and relate to the residual stress in the film. The colour is generally uniform (with some contrast where an additional thickness of film exists or where wrinkling has resulted in a different apparent thickness). This is indicative of both a uniform film thickness and of the uniformity of the drawing process used to make the film. In the region of the tear, however, the colours indicate strain-induced orientation: because the material is
Birefringence in a film of polypropylene
The colours in the image are the result of birefringence and relate to the residual stress in the film, following the biaxial stretching process. The uniformity of the colour (with contrast only where an additional thickness of film exists or where wrinkling has resulted in a different apparent thickness) is indicative of both a uniform film thickness and of the uniformity of the drawing process used to make the film. Note that unlike polyethylene, the film has not been permanently strained in
Ordered film of carbon nanotubes
It is necessary to form a stable dispersion of nanotubes in order to properly integrate them into polymeric systems. This can be achieved by treating them with acid to oxidise the tube surfaces. The tubes will then spontaneously disperse in an aqueous medium. The viscosity of these suspensions is analogous to that of polymers; it increases gradually with concentration up to a critical point (at about 0.7vol%) where entanglement occurs. A solid nanotube film has been formed by filtering the s
Interface boundary between h-BN and Si3N4 grains
The micrograph shows a regularly stepped interface boundary between h-BN (precipitate) and Si3N4 grains (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and

Delamination cracks in h-BN particles.
h-BN particles were subjected to compressive stress in the (0001) planes (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Su
Cybrids: Integrating Cognitive and Physical Space in Architecture
People regularly use non-physical, cognitive spaces to navigate and think. These spaces are important to
architects in the design and planning of physical buildings. Cognitive spaces inform design - often underlying
principles of architectural composition. They include zones of privacy, territory and the space of memory and
visual thought. They let us to map our environment, model or plan projects, even imagine places like Heaven
or Hell.
Cyberspace is an electronic extension of this cognitive
Envisioning Cyberspace: Designing 3D Electronic Spaces
Free of the constraints of physical form and limited only by imagination, new environments spring to life daily in a fantastic realm called cyberspace. The creators of this new virtual world may be programmers, designers, architects, even children. In this invigorating exploration of the juncture between cyberspace and the physical world, architect Peter Anders brings together leading-edge cyberspace art and architecture ... inspiring new techniques and technologies ... unexpected unions of real
Silal
This sample shows the typical structure of silal, irons with high Si content (5.5-7.9 wt%). It is a grey cast iron alloyed with 4-6wt% Si to provide good oxidation resistance. The high Si content forms a dense, adherent iron silicate surface film, which is resistant to oxygen penetration. The flake graphite iron Silal was one of the first heat resisting cast irons developed. Spheroidal graphite Si irons have higher strength and improved ductility. The structure shows cored dendrites of ferrite w

Developing a new endoscopy laboratory with digital tools.
Tampere School of Architecture had to leave its old down-town building and move to the TU Tampere university campus in Hervanta, 10 km away. In this process, the 20 years old endoscopic system "The Urban Simulator" was one of the victims. Old mechanical parts and especially the original home-built microcomputer system were too old to compete with modern computer-aided methods.
A new endoscopical system is now under construction, using all of the 20-year experience, new technical components and c
