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). Through t

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.
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.
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 recrystallised grains which which show uniform contrast because they are relatively free of dislocations, surrounded by a deformed matrix which has a high dislocation density. The recrystallised grain contains annealing twins (parallel bands with different contrast. The steps a
Uniform Estimate Experiment
This resource consists of a Java applet and expository text. The applet simulates a random sample from the uniform distribution on the interval [0,a], and computes standard point estimates of a. The bias and mean square error are also computed.
Advances in nanotechnology
In this podcast, Professor Moriarty discusses nanotechnology, and how it has led to a convergence of the traditional sciences. He talks about the commercial applications of nanotechnology such as hard disk technology in laptops, stain free materials and fabrics, self-cleaning windows and advanced water filtration. He also touches on some of the myths about nanotechnology as well as some of the real dangers of Nanotechnology and the steps governments are taking to regulate it. Professor Moriarty
Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)
FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly in
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 ab
Bivariate Uniform Experiment
This resource consists of a Java applet and expository text. The Java applet illustrates the bivariate uniform distribution on three types of regions: a square, a circle, and a triangle. Simulated points from the distribution are shown as dots in a scatterplot.
