Multi-Agent Transport Simulation | MATSim The Third Industrial Revolution: How the Internet, Green Electricity, and 3-D Printing are Ushering in a Sustainable Era of Distributed Capitalism By Jeremy Rifkin Our industrial civilization is at a crossroads. Oil and the other fossil fuel energies that make up the industrial way of life are sunsetting, and the technologies made from and propelled by these energies are antiquated. The entire industrial infrastructure built off of fossil fuels is aging and in disrepair. Since the beginning of the Great Recession in the summer of 2008, governments, the business community, and civil society have been embroiled in a fierce debate over how to restart the global economy. “It is becoming clear that the Second Industrial Revolution is dying. It is becoming increasingly clear that the Second Industrial Revolution is dying and that industrial induced CO2 emissions are threatening the viability of life on Earth. A New Economic Narrative The great economic revolutions in history occur when new communication technologies converge with new energy systems.

3-D Printed Windpipe Gives Infant Breath of Life PRINTED PART A cast of Kaiba Gionfriddo's airway with a 3-D printed splint in place Image: Courtesy The University of Michigan Health System Showcasing more than fifty of the most provocative, original, and significant online essays from 2011, The Best Science Writing Online 2012 will change the way... Read More » Kaiba Gionfriddo was six weeks old when he suddenly stopped breathing and turned blue at a restaurant. Kaiba’s parents quickly rushed him to the hospital where they learned that his left bronchial tube had collapsed because of a previously undetected birth defect. The trachea, or windpipe, is essentially constructed much like a vacuum cleaner hose, says Glenn Green, an ear nose and throat specialist (otolaryngologist) at the University of Michigan, who helped to develop the device. In most cases after a child is born, the cartilage in the trachea keeps the airway open. For unknown reasons, however, some cases are extremely severe.

Ten 100-year predictions that came true 11 January 2012Last updated at 00:09 By Tom Geoghegan BBC News Magazine John Watkins predicted Americans would be taller, tanks would exist and C, X and Q would no longer feature in our everyday alphabet In 1900, an American civil engineer called John Elfreth Watkins made a number of predictions about what the world would be like in 2000. As is customary at the start of a new year, the media have been full of predictions about what may happen in the months ahead. But a much longer forecast made in 1900 by a relatively unknown engineer has been recirculating in the past few days. In December of that year, at the start of the 20th Century, John Elfreth Watkins wrote a piece published on page eight of an American women's magazine, Ladies' Home Journal, entitled What May Happen in the Next Hundred Years. Watkins was a writer for the Journal's sister magazine, the Saturday Evening Post, based in Indianapolis. It was picked up and caused some excitement on Twitter. 1. 2. How did Watkins do? 3. 4.

Downloads The packages are automatically built based on the master branch on github.

Is radix sort faster than quicksort for integer arrays? discussion at reddit There are plenty of misconceptions and confusion over radix sort on the internet. The wikipedia article is messy and unclear, and focuses more on trying to explain the philosophy (for lack of a better word) than the characteristics and capabilities of radix sort. American Flag Sort Worst case performance: O(kN) Worst case space complexity: O(k log N) In Engineering radix sort McIlroy et al. discusses how radix sort can be used successfully to sort arrays of strings, using the American Flag Sort variant. Implementation The implementation proved to be surprisingly simple. “The troubles with radix sort are inimplementation, not in conception” - McIlroy et al. (1993) The complexity is O(kN) with k = 4 for 32-bit integers. It's important to note that complexity analysis of e.g. quicksort assumes that each comparison is O(1), which isn't true in practice on real hardware nor correct in theory when considering variable sized elements.

Complex models can be constructed from simple 3D primitives, or created using 3DCrafter's Shape Building Tools. Modeling tools are provided to deform, sculpt, and paint 3D shapes. Creating an animated scene is as simple as positioning the shapes within your scene for each point in time in your animation. 3DCrafter will ensure that the resulting animation runs smoothly. Your animation can be stepped through a frame at a time, viewed in real-time, or recorded to a Video (AVI) file so that you can distribute your creation. Tool roll-up groups allow you to customize the 3DCrafter interface so that only those items you use most frequently are visible. The standard version of 3DCrafter is a fully functional product provided as freeware. Feature Comparison 3DCrafter 9 is a free upgrade for anyone who purchased July 1st, 2010 or later.
