(PhysOrg.com) — Researchers at Michigan State University have built a prototype, based on the research first released in 2009, of the Wave Disk Generator — an engine that does not have pistons, crankshafts or valves. This new model, which does away with the internal combustion engine of the past, has the potential to reduce auto emissions up to 90 percent, when compared to the current emissions level. This is because the engine uses roughly 60 percent of its fuel for propulsion, when you compare this to the typical cars engine that uses only 15 percent of fuel for propulsion, we can see how the increase is possible.

Software patch makes car more fuel-efficient The new engine prototype is built with a disc-shaped shock wave generator that is about the size of a sauce pan, and will require no transmission system, cooling system, emissions regulation or fluids, which means that you will end up not only doing something good for the planet, but you will end up with less in maintenance costs, if this new prototype ever comes to the market.The engine works like this: a rotor, with a wave-like pattern carved into channels. The fuel and air enter and mix through the central inlets. The rotor then spins, blocking the exit of gasses. As the pressure builds it will generate a shock wave that will compress the mixture. Once it is ignited an outlet opens to let the hot gases escape, and your car can move as usual.The engine prototype was shown off by Norbert Müller and other colleagues at Michigan State University at a meeting with the Department of Energy’s Advanced Research Projects Agency. © 2010 PhysOrg.com Explore further

They also require an enormous amount of computing power, with the computer needing two hours of processing time for each second of Spaun simulation.The most surprising feature about Spaun, according to Prof. Eliasmith and colleagues is that it has human-like flaws. For example, it has trouble remembering lists of numbers when they are too lengthy, and is better at remembering numbers at the beginnings and ends of lists. It also hesitates before answering questions, just as humans do. These flaws may be useful in future robots, Eliasmith said, as they would make robots seem more human-like and therefore easier to interact with.

DOI: 10.1126/science.1225266ABSTRACTA central challenge for cognitive and systems neuroscience is to relate the incredibly complex behavior of animals to the equally complex activity of their brains. Recently described, large-scale neural models have not bridged this gap between neural activity and biological function. In this work, we present a 2.5-million-neuron model of the brain (called “Spaun”) that bridges this gap by exhibiting many different behaviors. The model is presented only with visual image sequences, and it draws all of its responses with a physically modeled arm. Although simplified, the model captures many aspects of neuroanatomy, neurophysiology, and psychological behavior, which we demonstrate via eight diverse tasks.Download the Spaun modelVideos for Spaun simulationsPress release ‘Chatter Box’ computer will unravel the science of language A high-level depiction of the Spaun model, with all of the central features of a general Semantic Pointer Architecture. © 2012 Phys.org (Phys.org)—One of the challenges of understanding the complex behavior of animals is to relate the behavior to the complex processes occurring within the brain. So far, neural models have not been able to bridge this gap, but a new software model, Spaun, goes some way to addressing this problem. Play This video shows Spaun’s ‘neural’ activity during four different tasks and explains how the researchers decoded it. Credit: Chris Eliasmith, et al. Eliasmith said Spaun is the first simulator of the brain to be able to complete a series of tasks and demonstrate behaviors, even though bigger brain models have been built in the past, such as that built by the Blue Brain Project, with a million neurons, and SyNAPSE (IBM) with a billion simulated neurons. Spaun is more similar to the human brain than previous models, Eliasmith said, and it could therefore be used in the study of some brain disorders. In a recent experiment, for example, he examined the effects of neurons “dying off,” in a simulation of aging of the human brain; an experiment that would have been unethical if using human subjects. The model might also be useful in the development of multi-task artificial intelligence applications, and robotics.Spaun does have its limitations because at present it can only carry out the tasks given it and cannot learn anything new, and because of its lengthy computer processing time. The research paper was published in the journal Science. The Semantic Pointer Architecture Unified Network (Spaun) is a computer model of the human brain built by Professor Chris Eliasmith and colleagues of the University of Waterloo in Canada. It comprises around two and a half million virtual neurons organized into functional groups rather like real neurons in regions of the human brain associated with vision, short-term memory, and so on. (The human brain has roughly 100 billion neurons.) Spaun is presented with a sequence of visual images in eight separate tasks. It then processes the information presented to it and then decides what action to take. It can recognize and remember numbers written in different handwriting, and can copy them using a mechanical arm. Spaun can also answer questions about numbers and complete number series after seeing examples.
The conclusion of CRY’s forty day long photo journalism campaign – Click Rights – Focus on the Child, was marked by an exhibition in the Capital. The exhibition displayed photographs illustrating the reasons that keep so many Indian children out of school. These photographs have been contributed by concerned citizens across the country as well as some of India’s finest photographers. The campaign is an outcome of the belief that a powerful visual can convey the situation far better than words and can inspire large scale social change.

With a focus on the youth our campaign partners ranged from students’ groups from reputed academic institutions like IIT Kharagpur, IIT Delhi, Institute of Home Economics, Delhi and IIM Calcutta. Corporates like HCL Technologies Foundation, MTS, HP, Mu Sigma and Mphasis and Photography Clubs like Nazar Foundation, National Academy of Photography and Photopeer supported the campaign as partners.
We asked Lucky Ali to tell us about himself. He answered like a rockstar of a poet and shut us up from trying to delve more into his life. ‘Am still searching for the part of me that was before O Sanam, once I find it – there will be a song about it.’ But he laughs and adds that he has always been interested in learning to play music and compose and had he not been a musician he would have definitely been into academics. We’re just very glad he picked music! Also Read – ‘Playing Jojo was emotionally exhausting’Ali was in the Capital to perform for the Bacardi NH7 Weekender and for those who missed it, he’s performing in the Kolkata chapter as well. Catch him if you can! O Sanam, Anjani Rahon Mein, Mausam, Milegi Milegi Manzil, Sunoh, Aap Par Arz Hai are songs we have grown up with and strangely these songs are more indelibly fixed in our memories than the Bollywood songs Ali has sung. But , we must ask – why have we not seen an album from Ali in so long? That’s because he has been releasing his music online, he says. But coming from the age where cassettes and cds mattered, doesn’t releasing music online seem odd? ‘The whole industry has changed, at the end of the day people are still listening to music and that’s what matters!’ says Ali adding that there’s far more music happening online than on television. ‘It felt cheap asking for money for music. I released my songs through social media and I got the response I was looking for,’ he says. Also Read – Leslie doing new comedy special with NetflixSo what about Bollywood? ‘By virtue of birth I was born into Bollywood…I wanted to get out!’ says the man leaving us bewildered. But Ali explains that he doesn’t fit in Bollywood, that music isn’t his ‘kind’ of music. But as ‘the road to hell is full of good intentions’ (and we quote!) – Ali has lent his voice to some brilliant Bollywood songs, but only for a virtue called friendship. And what’s keeping Ali busy these days? Lots of collaborations and compilations and of course – travel and family, he says adding that, ‘Things have gone beyond releasing an album. It is more about finishing a song and pushing it over SoundCloud.’ But no matter where the song is, Ali believes that ‘music is constant, people will always be open to listening to music!’Ali grew up with the likes of Led Zeppelin and Metallica, these legends taught him all about the ‘feel’ of the song but the melody comes from India. Naming Kailash Kher, Rabbi, AR Rahman, Raghu Dixit, Rahat Fateh Ali Khan as his favourites, Ali says that people express themselves differently in music. But that is where the magic is.
My friends always insist that I should go to Mumbai and be an actor. I am handsome and smart. I’m 19 years old. How do I become an actor? My parents insist I continue my studies and do my Management.Satya, LucknowSatya, in our country we really have fantasy towards the tinsel town. I’m sure that you have the potential to try your hands in acting. But at the same time, you must understand the level of competition one has to face and overcome to make it to films. I suggest, you finish your graduation and try your luck. Parents usually think well for us. Give yourself a few years, show your determination to them make them understand how serious you are about your dream. In the meantime, hone your abilities as an actor. Enroll in a good gym, learn acting, watch good movies, read about world cinema and prepare to plunge. Good luck! Also Read – ‘Playing Jojo was emotionally exhausting’I got married very early. We eloped when I was 16 and he was 20. I am a mother of a 3 year old now. I have recently discovered that my husband is having many extra marital affairs. I’m shattered. How can I stop him?Name not givenIt is not easy to really stop anyone from doing anything. But, you should do everything to try and stop this. Words, emotional blackmail, threats, tears… use every weapon possible to rectify this situation. Confront him directly and warn him about the ugly consequence that one has to face for adultery. The age is sometimes the reason why there is a lack of maturity and may be with time the situation will improve. Also Read – Leslie doing new comedy special with NetflixWe are married for 12 years. Our sex life has lost its charm. Things have got downright boring. Sex seems to always be the same old story. How to start afresh, is it possible.Mrs and Mr Bhagat, New DelhiBreak out of your rut. Try something new. You don’t have to go crazy or anything. But you can change positions and try the ones you have never done before. You can spice it up with extra foreplay, sex toys, sexy lingerie, dirty talk, or a hot massage. Even something as simple as a romantic dinner or weekend can make the sex life better. I am a divorcee. I got attracted to my brother-in-law who helped me a lot in my divorce process. He is years younger to me but I love him a lot. But don’t know whether he loves me or not. What should I do in such situation? How do I gauge his true feelings?Name unknown, PuneYou are caught in a cleft stick. You haven’t written the reason for your divorce. In India, we find that most of divorce cases are caused by the pressure of living in a joint family. And if your case is also the same, then I do not think that any close association in that family is advisable. We all need good friends and company and this loneliness is the reason why you have got attracted to your brother-in-law. No doubt he adores you a lot but do not make the mess of your life.He might have helped and supported you only because his brother did wrong to you. So it’s better to live the life as its going and if something would be positive from his side then he himself will propose you! Have a love or life query you cannot find an answer to?
