24.111 Philosophy of Quantum Mechanics (MIT)
Quantum mechanics--even in the ordinary, non-relativistic, "particle" formulation that will be the primary focus of this course--has been a staggeringly successful physical theory, surely one of the crowning achievements of 20th century science. It's also rather bizarre--bizarre enough to lead very intelligent and otherwise sensible people to make such claims as that the universe is perpetually splitting into many copies of itself, that conscious minds have the power to make physical systems "ju
Why is Nanotechnology Multidisciplinary? A perspective of one EE
The field of nano-science and nano-technology covers a broad area of expertise. Classical fields of Physics, Chemistry, Material Science, Electrical/Mechanical/Chemical Engineering all are involved in the "new" field f nano. Research and development in that area is by its very nature multi-disciplinary, since I bridge a large length scale from atoms to systems and timescales from femto seconds to eternity. This presentation will give a personal perspective of an electrical engineer in the area o
Has Mish Deflated the "Inflationistas"? Over the last two years, I have gotten perhaps dozens of requests to "deal with" the deflationist approach of Mike "Mish" Shedlock. On his popular financial blog, Mish has been repeatedly patting himself on the back for correctly calling all the major trends in contrast to those economists (like Author(s):

Public Spaces on the Information Highway: The Role of Community Networks
This thesis explores the phenomenon of community networking in Canada, particularly as it impacts the issue of universal access to emerging broadband networks. The regulatory context of community networking is examined, and recent government efforts reviewed and critiqued. Through two case studies, an analysis of three potential benefits arising from community networking is developed. These three benefits are: increased participation in the democratic system, increased access to education, and c
Design Algorithms after Le Corbusier
Some views of design are the act as puzzle making, problem solving, evolutionary, and decision-making. All these focus on form generation as constructive, therefore characterizing design as a path-planning problem through a space of possibilities. Design problems consist sets of information divided into initial, intermediate, and goal states. Design in its simplest state consist of a set of operators, sequences (or paths) between initial and goals states. In this paper, I present design algorith
Austenitic stainless steel
This is a transmission electron micrograph taken at 200 kV, from a thin foil sample of "302AA" austenitic stainless steel. The sample was cold-deformed by rolling and then annealed at 704 °C for one hour. The image shows a beautiful picture of annealing twins. Notice how the ends of annealing twins are flat, the shape being determined by a minimisation of interfacial energy. Mechanical twins, by contrast, are lenticular (lens like) with sharply pointed ends to minimise the strain energy due to
Wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute; refined with TiB2 particles. Deformation of grain structure is due to cutting of sample with scissors. This micrograph illustrates the effect of deformation on a previously equiaxed structure. Strain causes the elongation of grains and the subsequent anodising produces 'mottled' grain colours; the oxide layer is not of constant orientation or thickness across a grain.The Barker's etch and applied electrical field produce a thick
Preserva??o e Gest?o de S?tios Hist?ricos: a contribui??o do Heritage Information System [Preservati
The present article aims to discuss the application of the digital technologies in the preservation and management of cultural heritage development. The GIS is used by the international agencies heritage like UNESCO. The GIS applications that are largely applied in built cultural heritage are internationally known as Heritage Information System ? HIS. In HIS, the space configuration of the historical sites is represented by a map or for a DTM, with the quantitative and qualitative attributes, 3D
Imagen del espacio p?blico e imagen digital (Image of the public space and digital image)
This paper refers to the concept, image and meaning of the public space in media size cities. The premise is the displacement of the social comprehension and valuation of the public due to economical, political and cultural features of contemporary. The concept of public understood as an adjective of urban space moves to the public as a substantive that refers to a general condition of life in city. Digital image and its informational manipulation are the main resources for processing the public
GESTI?N DIGITAL URBANA ROSARIO (Digital Management of Urban Rosario)
This project is aimed at developing an instrument to reach the city-net multidimensionality (flux /real-space) of Rosario city in Argentina. Both, an integral view and the view of the different information layers of the urban net are required. We decided the used of computers to determine a digital dynamic model. The tool proposed has to be useful not only in search and urban survey but also as a design instrument, to pre-view the urban interventions. Simultaneously this tool is needed to evalua
Fracture surface in a liquid crystalline polymer
Above their melting point, liquid crystalline polymers exhibit a mesophase within which, although able to flow and are not arranged in a crystal, they exhibit long range orientational order. This molecular alignment can be exploited to make high strength and stiffness fibres such as Kevlar, or even mouldable thermotropics such as Vectra. Molecular alignment can also be controlled by an external applied field; a property exploited in liquid crystal displays. This specimen has not had a magneti

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 0.7 vol%) where entanglement occurs. However, their separation is determined more by surface
Ordered film of carbon nanotubes

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
Anthropic Cyberspace: Defining Eletronic Space from First Principles
This paper proposes principles for the design of human-centered, anthropic cyberspaces. Starting with a brief examination of our cognitive use of space, it suggests that we address cyberspace as an extension of our mental space. The paper procedes with twelve concepts based on scientific and cultural observations with respect to individual cognition and social interaction. These concepts are general - not specific to any culture or technology in the accompanying arguments the author expands on t
Advanced techniques of design in support to medical science: Application to implantological treatmen
At the present time the importance of the image of people plays a key role. Therefore many people who leave these standards wish to change their aesthetic face one, in occasions to look for characteristics that respond to the modern beauty, and in others, to try to solve a medical problem. In the work that is exposed here, the use of the present technological tools of design appears, like support to the scientific development that it makes possible an effectively learn more express and to the st
Technical Aspects of the Urban Simulator in Tampere University of Technology
The colour video recording Urban Simulator in TUT was built very early compared with the development of video systems. A contract for planning the simulator electronics, mechanics and camera systems was made in january 1978 with two TUT students: Jani Granholm (computer science and engineering) and Ilkka Alavalkama (machine design and automation). Ease of control and maintenance were asked by side of ?human movement inside coloured small-scale architectural models?. From the beginning, all compo
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
