Blast Load Simulation of Floating Barricade System to Protect Anchored Vessels
Simulation created using the CFD code named CEBAM (Computational Explosion And Blast Assessment Model). CEBAM is capable of simulating blast loads from high explosive, vapor clouds, and bursting vessels. Floating barricade system used to increase standoff and hence reduce blast loading on anchored vessels. Research performed by Risknology, Inc.
Can kindergarten children be successfully involved in probabilistic tasks?
This paper describes a classroom teaching experiment, concerning the concept of probability, with children aged 5 in a kindergarten school. The teaching experiment was based on constructivist and interactionist theories about the learning of school mathematics and lasted one month. The collection of the information was based on the tape-recorded interviews with the children (each child was interviewed prior to the research program, at the end of the program and one month later) and the videotape
Historic Pittsburgh, an extensive digital resource created at the University of Pittsburgh, offers both an entry point and substantive classroom resources for teachers of American History at various grade and university levels. This Web site enables access to historic material held by the University of Pittsburgh's University Library System, the Library & Archives at the Heinz History Center, Carnegie Museum of Art, Chatham College Archives, Pittsburgh History & Landmarks Foundation, and Point
This unit looks at some of the architectural and programming paradigms used in distributed system development. You will learn about synchronous and asynchronous message passing, distributed objects technology and event-based bus architecture, before finally moving on to tuple architecture.
An Introduction to the Patent System
This 17-minute video is designed to be shown to jurors in patent jury trials. It contains important background information intended to help jurors understand what patents are, why they are needed, how inventors get them, the role of the Patent and Trademark Office, and why disputes over patents arise. An Introduction to the Patent System was developed with the assistance of an advisory committee of district judges and patent attorneys. Special care was taken to ensure that it provides an imparti
Inside the Federal Courts
One of the Federal Judicial Center's duties is to teach federal court employees about how the courts work, how they are organized, and how they fit into the U.S. system of government. We developed this site as an easy reference to help court employees understand aspects of the federal courts outside of their specific responsibilities. We put it on our public website because it may also help students, the media, and the public learn more about the federal courts.
Building theories: working in a microworld and writing the mathematical notebook
In the framework of a long term teaching experiment we present an Educational approach based on the use of a dynamic geometry software and a symbolic manipulator. Here we present the general ideas of the followed approach focusing on how meanings can originate from phenomenological experience and evolve under the guidance of the teacher. In particular we will focus on meanings related to the ideas of theory, axiom and theorem.
Introduction to Climate Dynamics and Climate Modeling (CA Textbook)
A comprehensive analysis of all the components of the climate system (atmosphere, ocean, ice sheets, etc) and of all the interactions between them is out of the scope of any course or book. We have thus chosen here to provide only a brief overview of the processes that rule the behaviour of those different components. More detailed descriptions are provided in meteorology, oceanography and glaciology courses for instance. Our first goal here is rather to provide enough information on the interac
11.123 Big Plans (MIT)
This course explores social, technological, political, economic, and cultural implications of "Big Plans" in the urban context. Local and international case studies (such as Boston's Central Artery and Curitiba, Brazil's bus transit system) are used to understand the process of making major changes to the city fabric. The efficacy of top-down and bottom-up planning and the applicability of planning strategies across cultural boundaries are considered.
Guns and Rubles
Professor Mark Harrison discusses Stalin, the Great Terror, and how defense was at the core of Stalins system of rule.
Is the 'Rule of Law' Good for Cities?
There is a widespread consensus that, everywhere in the world, urban development has to be based on the rule of law. But what is 'the rule of law'? Does any formal legal system qualify – or must it have specific requirements? If there are specific requirements, who says what they are? Does the rule of law inhibit – or does it encourage – the extent of privatisation of urban space? Does it require the abolition of informal settlements and businesses or allow them? This lecture will investig
Economic Agendas in a Global Context: reflections on the role of Korea
The global economy is going through a turbulent time and it is time for a fundamental re-design of the global economic system. In doing this, Korea has a unique set of assets to provide. It is one of the few countries that have transformed itself from one of the poorest to the one of the industrialized in living memory, so it can understand the concerns that span across a huge spectrum of countries. In this lecture, Ha-Joon Chang will discuss how Korea can, and should, contribute to the reform o
Jimmy Stewart Is Dead -- Ending the World's Ongoing Financial Plague with Limited Purpose Banking
Let's call a spade a spade. Today's financial system, with its limited liability, insider rating, political kickbacks, director sweetheart deals, non disclosure, and internal corporate raiders, was built for hucksters -- hucksters who systematically manufactured and sold trillions in fraudulent securities, grabbed hoards of loot, and left the public to pick up the pieces.
The Coming Global Monetary (Dis)Order
After the Great Recession, the global monetary system is in turmoil. Can order be restored?
Glass ceramic, heat treated at 750°C for 3 hours
Glass ceramics are materials that are cooled from the melt in the form of a glass, and then heat treated to induce controlled crystallisation of the glass. Heterogeneous nucleation is carried out at a temperature to maximise the nucleation rate (common nucleating agents include TiO2 and ZrO2), and the temperature is then raised sufficiently to cause the nuclei formed to grow rapidly. Glass ceramics are strong, reasonably tough, transparent to IR radiation, have a low coefficient of thermal expa
Al 88, Si 12 (wt%), eutectic alloy
This sample is a casting alloy of eutectic composition. From the melt a eutectic is formed between aluminium solid solution and virtually pure silicon. Slow solidification produces a very coarse microstructure. The eutectic comprises large plates of silicon in the aluminium matrix. This microstructure displays poor ductility due to the brittleness of large silicon plates. The microstructure is normally refined through either rapid solidification, which lets the silicon phase assume a fibrous fo

Stem Cells: Programming and Personalized Medicine
After years of relentless lab work, rising and falling expectations, and the challenge of a sometimes hostile public, Rudolf Jaenisch says, “The scenario that looked like a fantasy … has come closer to reality. We can study complex human diseases in a Petri dish and potentially contribute to therapy.” In this l
