    The device, like dolphins, sends out two pulses in quick succession to allow for a targeted search for semiconductor devices, cancelling any background "noise",

    and it sends out two pulses of opposite polarity, in succession, such that a semiconductor changes the negative to a positive one, amplifying the returning signal. Very interesting. Maybe we can combine different frequencies for identifying a single variable in earth observation. We already use more that one frequencies but for identifying one variable each.

    Could it be used to measure ocean acidification? I found a study that links sound wave propagation with ocean acidity. Maybe we are able to do such measurement from space even? "Their paper, "Unanticipated consequences of ocean acidification: A noisier ocean at lower pH," published last week in the journal Geophysical Research Letters, found that fossil fuels are turning up the ocean's volume. Since the beginning of the Industrial Revolution, the overall pH of the world's oceans has dropped by about 0.1 units, with more of the changes concentrated closer to the poles. The authors found that sound absorption has decreased by 15 percent in parts of the North Atlantic and by 10 percent throughout the Atlantic and Pacific"

    The last time I asked an oceanographer for the use of acoustic waves, she said it is still a bit problematic method to take into account its data, but we were referring to measuring ocean circulation. It may be more conclusive for PH measurements, though. The truth is that there is a whole underwater network with pulse emmitters/receivers covering the North Atlantic basin, remnant infrastructure for spying activities in the WW2 and in the cold war, that stays unexploited. We should look more into this idea

    A pretty standard Apple-o-getic (ah ah) blog post. How many times does the guy say 'I like Apple'? Anyway, I'm having a hard time understanding the point he is trying to make. Apple should open up its innovation? It shouldn't because they are so hip, cool, a 'unique company' and an 'exception to the rule'? Mah..
  • Ma Ru on 14 Jun 10
     
    I think the point is the guy bashes the "open innovation theory" (whatever the theory is) with his main argument being that Apple is not open and at the same time very successful.
  • LeopoldS on 14 Jun 10
     
    this guy is actually one of the most fervent supporters of open innovation and tries to promote it whereever he can ... his problem is that at least at first view Apple does not confirm his theory ...

    lol, the 'about' page is priceless bullshit: http://www.15inno.com/about-15inno/ "Corporate Mind Exchange (CMX) events in which corporate innovation leaders discuss relevant challenges and issues. No academics, consultants or start-ups; just corporate practitioners." We are doing it wrong, Leo. We don't need no stinking Universities! "Network groups in which 12-20 innovation leaders from different companies meet 4-6 times annually to discuss challenges and issues. Workshops and events with thought leaders and practitioners." What the hell are "innovation/thought leaders"?

shared by Juxi Leitner on 23 Jul 10 - Cached
  • Foursquare is now being widely touted as the app which will, after years of anticipation and prediction, mark the beginning of "life as a game" computing. Whatever you do, wherever you go, you will be scoring points, earning "medals", and be in, at the very least, social competition with other users around you.
  • Privacy seems to be very low down their priorities. In theory, if every user knows the risks, this is fine. But they just don't. It's being targeted at 18 to 25-year-olds. Facebook was forced in the end to change its default privacy settings due to public concerns. Foursquare should do the same. Some people are even checking in when they're at home. Think of the implications. It's crazy
  • Recruitment is a form of stalking, I suppose. But I can now see the negative implications of Foursquare in the real world.
  • ...1 more annotation...
  • Ten days ago Foursquare reached the two-million-users landmark, just three months after it had reached the one-million mark. A week earlier, the company received $20m in venture capital from a who's who of Silicon Valley luminaries. It appears the trajectory for Foursquare is only upwards. But as the critical mass of Foursquare users swells and intensifies over the coming months and years, the concerns over privacy are likely to magnify. In June, Webroot, a Denver-based internet security firm, surveyed 1,645 users of "geo-location-ready mobile devices", including 624 in the UK: 29% said they shared their location with people other than their friends; 31% said they accepted a friend request from a stranger; and, yet, 55% still said they were worried about their loss of privacy.

    so what are they then? ... and don't tell me "fungi" now ..
  • Tobias Seidl on 25 Jan 10
     
    Well, it has always been a long discussion. Fungi are according to the most recent findings definitely no plants. Since they have always been in botanic textbooks, I would assume that they were never considered animals.No fauna, no flora, no stones. Maybe they are extraterrestrials. But that wouldn't solve the questions. Maybe they are just "fungi"?

Superconductors could simulate the brain - 2 views

superconductors brain

shared by pacome delva on 08 Mar 10 - Cached
  • who have shown how networks of artificial neurons containing two Josephson junctions would outpace more traditional computer-simulated brains by many orders of magnitude. Studying such junction-based systems could improve our understanding of long-term learning and memory along with factors that may contribute to disorders like epilepsy.
  • The existing design does not permit learning since the weighting of connections between synapses cannot be changed over time, but Segall believes that if this feature can be added then their neurons might allow a lifetime's worth of learning to be simulated in five or ten minutes. This, he adds, should help us to understand how learning changes with age and might give us clues as to how long-term disorders like Parkinson's disease develops.
  • Christos Ampatzis on 09 Mar 10
     
    What I don't get is how the measure the extent of matching: how "close", or realistic is the modelisation they achieve with different methods? And moreover, if weights cannot adapt and there are no direct connections between neurons and layers of neurons, isnt that a very arbitrary matching?
