APW2010: Divergent Dictators: Legacies of Leadership in Three Asian Authoritarian Regimes
"Finding the right place for individuals is an old problem for political analysis," explains Richard Samuels in his comparative analysis of leadership in Japan and Italy. "Do individuals make history, or does history make individuals who make history?" This paper examines the highly divergent legacies that came forth from the leadership of three Asian dictators: South Korea's Park Chung Hee (1961-1979), Indonesia's Suharto (1965-1998), and the Philippines' Ferdinand Marcos (1965-1986).

18.100A Analysis I (MIT)
Analysis I (18.100) in its various versions covers fundamentals of mathematical analysis: continuity, differentiability, some form of the Riemann integral, sequences and series of numbers and functions, uniform convergence with applications to interchange of limit operations, some point-set topology, including some work in Euclidean n-space.
MIT students may choose to take one of three versions of 18.100: Option A (18.100A) chooses less abstract definitions and proofs, and gives applications whe

Using domain-specific and generic knowledge to support discovery learning about geometrical optics i
Students encounter many obstacles during scientific discovery learning with computer-based simulations. It is hypothesized that an effective type of support, that does not interfere with the scientific discovery learning process, should be delivered on a ‘just-in-time’ base. This paper explores the effect of facilitating access to knowledge and skills through just-in-time information. An experiment was conducted in which a group of students who worked with a computer simulation on geometrica
The Metaphor of Networks in Learning: Communities, Collaboration and Practice
This paper explores the use of the network metaphor and the way in which it relates to Computer Supported Collaborative Learning (CSCL) and Communities of Practice. The idea of networked learning stresses the interactopn of learners, tutors and their resources through networks. The arguments put in this article are firstly that learning technology needs to take account of the wider debate about networks and secondly that research in this field needs to address the theoretical and practical issue
Re-engineering of collaborative e-learning systems: evaluation of system, collaboration and acquired
This paper relates an experimentation of a collaborative e-learning system.
In this kind of system, tracks arising from communication tools allow to build useful
indicators for all system actors. We show how tracks are analyzed and how this
analysis is useful for reengineering purposes.
Methods of presetting material
Presetting involves bending the ends of material before it is formed into a cylindrical or conical shape. Presetting is important because it ensures the product will be uniform in shape and will have a smooth transition at the seams. When a cylinder is made using pyramid rolls, the ends remain flat. This is because when the material passes through the rollers, it doesn't start to bend until after it gets to the last roller on the machine. The extra material is cut off to ensure a smooth join.
Uniform convergence and pointwise convergence
The aim of this material is to introduce the student to two notions of convergence for sequences of real-valued functions. The notion of pointwise convergence is relatively straightforward, but the notion of uniform convergence is more subtle. Uniform convergence is explained in terms of closed function balls and the new notion of sets absorbing sequences.
The differences between the two types of convergence are illustrated with several examples. Some standard facts are also discussed: a unif
FOAMCARP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. Calcium carbonate is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a fine and relatively uniform cell structure.
FORMGRIP closed cell aluminium foam
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% of pre-oxidised titanium hydride is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a relatively fine and uniform cell structure.
A Critical Approach to the Use of Computers in Architectural Design
There are two dominant approaches to architectural and urbanistic problem solving: program based approaches and paradigm based approaches. Beyond these two, this paper proposes the critical/formalist approach as a paradigm for architectural design while summarizing the epistemological foundations of it, and investigates the possible contribution of the computers to this approach. The primary aim is to set a starting point for a more comprehensive future research.
Development of Digital City Models Using 3d GIS
?Digital city? is a copy of an actual city in the virtual space. It is expected to play an important role in urban planning, disaster simulation etc. Recent advanced remote sensing technologies, which are capable to quickly provide detailed information of city areas, ease the construction of 3D city models. Urbanization has evinced interest from a wide section of the society including experts, amateurs and novices. With the development and infrastructure initiatives mostly around the urban cente
