Artificial neural network An artificial neural network is an interconnected group of nodes, akin to the vast network of neurons in a brain. Here, each circular node represents an artificial neuron and an arrow represents a connection from the output of one neuron to the input of another. For example, a neural network for handwriting recognition is defined by a set of input neurons which may be activated by the pixels of an input image. 15 of the best 3D-printed items from 2013 Helen Foley is Marketing Executive at Elanders, a global printing group with production units in nine countries on four continents. Love it or hate it, 3D printing is here to stay. It is considered the future of print and manufacturing, and is set to dramatically change the way we buy and produce products in the future. Over the years, experts have been researching and developing different concepts, printing designs and processes and several breakthroughs have been made — including a working 3D kidney made in 2002 by the Wake Forest Institute and a prosthetic leg, inclusive of the knee and foot, etc. made in 2008 by Bespoke Innovations. Outside of professional and engineering circles, consumers have been able to get their hands on the first affordable devices that are powerful enough to produce small 3D printed objects, mainly through Kickstarter projects.
Bioengineers Build Open Source Language for Programming Cells Drew Endy wants to build a programming language for the body. Endy is the co-director of the International Open Facility Advancing Biotechnology — BIOFAB, for short — where he’s part of a team that’s developing a language that will use genetic data to actually program biological cells. That may seem like the stuff of science fiction, but the project is already underway, and the team intends to open source the language, so that other scientists can use it and modify it and perfect it.
4-D Printing Means Building Things That Build Themselves : All Tech Considered hide captionH. Jerry Qi, associate professor of mechanical engineering at Colorado University, holds simple models printed using polymers that have "shape memory." The flat piece on the left can reshape itself into a box with the application of heat. Glenn J. Solar System Exploration Research Virtual Institute Building a base on the moon could theoretically be made much simpler by using a 3D printer to construct it from local materials. The concept was recently endorsed by the European Space Agency (ESA) which is now collaborating with architects to gauge the feasibility of 3D printing using lunar soil. “Terrestrial 3D printing technology has produced entire structures,” explained Laurent Pambaguian, heading the project for ESA. “Our industrial team investigated if it could similarly be employed to build a lunar habitat.”
19-Year-Old Student Develops Ocean Cleanup Array That Could Remove 7,250,000 Tons Of Plastic From the World's Oceans 19-year-old Boyan Slat has unveiled plans to create an Ocean Cleanup Array that could remove 7,250,000 tons of plastic waste from the world’s oceans. The device consists of an anchored network of floating booms and processing platforms that could be dispatched to garbage patches around the world. Instead of moving through the ocean, the array would span the radius of a garbage patch, acting as a giant funnel. The angle of the booms would force plastic in the direction of the platforms, where it would be separated from plankton, filtered and stored for recycling. At school, Boyan Slat launched a project that analyzed the size and amount of plastic particles in the ocean’s garbage patches. His final paper went on to win several prizes, including Best Technical Design 2012 at the Delft University of Technology.
The business plan Some people contact us from time to time asking where is our business plan, if we can share it with them. We’d love to, but the truth is that there is no formal business plan. Not any … at all. SolarSinter : markus kayser Solar Sinter 2011 In August 2010 I took my first solar machine - the Sun-Cutter - to the Egyptian desert in a suitcase. This was a solar-powered, semi-automated low-tech laser cutter, that used the power of the sun to drive it and directly harnessed its rays through a glass ball lens to ‘laser’ cut 2D components using a cam-guided system. The Sun-Cutter produced components in thin plywood with an aesthetic quality that was a curious hybrid of machine-made and “nature craft” due to the crudeness of its mechanism and cutting beam optics, alongside variations in solar intensity due to weather fluctuations.
The 150 Things the World's Smartest People Are Afraid Of Every year, the online magazine Edge--the so-called smartest website in the world, helmed by science impresario John Brockman--asks top scientists, technologists, writers, and academics to weigh in on a single question. This year, that query was "What Should We Be Worried About?", and the idea was to identify new problems arising in science, tech, and culture that haven't yet been widely recognized. MIT Creates New Energy Source This is some pretty exciting news. It seems that researchers at the Massachusetts Institute of Technology (MIT), one of the most prestigious science and engineering schools in the United States, has created a new energy source -- and it's clean and renewable. The odd thing is that the only way you can see this energy source is with a very powerful microscope, because it is created by using nanotechnology. For a few years now, we have been hearing about the possibilities offered by the new field of nanotechnology.
3D Printing Lawsuit Brings A Flurry Of Negativity On Reddit With 3D printing looking to be one of the next big sectors in technology, everyone knew the patent battles would begin. 3D printing hit this landmark recently with Stratasys’s announcement it was suing Afinia for infringement. From Minneapolis Star Tribune: The suit, filed in federal court in Minneapolis, seeks unspecified damages from Microboards and a permanent injunction preventing sales of the Afinia printer. Stratasys alleges violation of four of its patents.The Stratasys patents in the suit cover the ways a 3-D model is created by spraying liquid material that hardens to form an object.One Stratasys patent is about the rate at which liquid material is sprayed to give the model different degrees of hollowness between its layers.
The Turing Test First published Wed Apr 9, 2003; substantive revision Wed Jan 26, 2011 The phrase “The Turing Test” is most properly used to refer to a proposal made by Turing (1950) as a way of dealing with the question whether machines can think. According to Turing, the question whether machines can think is itself “too meaningless” to deserve discussion (442). However, if we consider the more precise—and somehow related—question whether a digital computer can do well in a certain kind of game that Turing describes (“The Imitation Game”), then—at least in Turing's eyes—we do have a question that admits of precise discussion. Moreover, as we shall see, Turing himself thought that it would not be too long before we did have digital computers that could “do well” in the Imitation Game.
27 Science Fictions That Became Science Facts In 2012 We may never have our flying cars, but the future is here. From creating fully functioning artificial leaves to hacking the human brain, science made a lot of breakthroughs this year. 1. Quadriplegic Uses Her Mind to Control Her Robotic Arm At the University of Pittsburgh, the neurobiology department worked with 52-year-old Jan Scheuermann over the course of 13 weeks to create a robotic arm controlled only by the power of Scheuermann’s mind. The team implanted her with two 96-channel intracortical microelectrodes.
