Bio-Mimetic Approaches in Management Science, Book - Barnes & Noble - 1 views

  •  
    Oh yes somebody seems to have found a link between CMS and Biomimetics. Everything is possible now, even Fundamental physics !
  •  
    Neural networks = biomimetics. That's the conclusion from the TOC. It seems that biomimetics becomes the worse usurper than string theory.

Putting 1.6TB on a DVD sized disk using muliplexed optical recording @Nature - 0 views

  •  
    Multiplexed optical recording provides an unparalleled approach to increasing the information density beyond 1012 bits per cm3 (1 Tbit cm-3) by storing multiple, individually addressable patterns within the same recording volume. Although wavelength, polarization and spatial dimension have all been exploited for multiplexing, these approaches have never been integrated into a single technique that could ultimately increase the information capacity by orders of magnitude.

SiG | Social Innovation Generation - 0 views

  •  
    How about that for an abstract discipline, and I thought CMS was abstract. Sounds great though: Social Innovation Generation: "Social innovation is an initiative, product, process or program that profoundly changes the basic routines, resource and authority flows or beliefs of any social system. Successful social innovations have durability and broad impact. While social innovation has recognizable stages and phases, achieving durability and scale is a dynamic process that requires both emergence of opportunity and deliberate agency, and a connection between the two."

  •  
    Carrier multiplication (CM) is a process in which absorption of a single photon produces not just one but multiple electron-hole pairs. This effect is a potential enabler of next-generation, high-efficiency photovoltaic and photocatalytic systems.

How Michael Osinski Helped Build the Bomb That Blew Up Wall Street -- New York Magazine - 0 views

  • You needed models to create the intricate network of bonds based on the homeowners’ payments, models to predict prepayment rates, and models to predict defaults. You needed the Internet to sail these bonds back and forth across the world, massaging their content to fit an investor’s needs at a moment’s notice. Add to all this the complacency, greed, entitlement, and callous stupidity that characterized banks in post-2001 America, and you have a recipe for disaster.

18-year-old massively improves supercapacitors during Intel International Science and E... - 1 views

  •  
    "Her goal was to design and synthesise a super capacitor with increased energy density while maintaining power density and long cycle life. She designed, synthesised and characterised a novel core-shell nanorod electrode with hydrogemated TiO2(H-TiO2) core and polyaniline shell. H-TiO2 acts as the double layer electrostatic core. Good conductivity of H-TiO2 combined with the high pseudo capacitance of polyaniline results in significantly higher overall capacitance and energy density while retaining good power density and cycle life. This new electrode was fabricated into a flexible solid-state device to light an LED to test it in a practical application. Khare then evaluated the structural and electrochemical properties of the new electrode. It demonstrated high capacitance of 203.3 mF/cm2 (238.5 F/g) compared to the next best alternative super capacitor in previous research of 80 F/g, due to the design of the core-shell structure. This resulted in excellent energy density of 20.1 Wh/kg, comparable to batteries, while maintaining a high power density of 20540 W/kg. It also demonstrated a much higher cycle life compared to batteries, with a low 32.5% capacitance loss over 10,000 cycles at a high scan rate of 200 mV/s."

Meteorite Crashes In Russia, Panic Spreads (Updating) - 5 views

  •  
    Latest update: the European Space Agency says their experts "confirm there is no link between the meteor incidents in Russia and asteroid 2012DA14 flyby tonight". How did they find this? As they did not see this one coming, how could they come to that conclusion that early!
  • ...5 more comments...
  •  
    As you can see from the videos of this meteorite it is coming in from an east to south-east direction (i.e. the direction of the sunrise, more or less). 2012DA14 is coming from due south as you can see here: http://www.wired.com/wiredscience/2013/02/how-to-watch-asteroid-2012-da14/ So the two objects seem to be coming from different directions - at least that would be my explanation.
  •  
    My point is, that if you want to come to such a conclusion (that it is not rubble) you need to be able to construct back the orbits of both objects. 2012DA14 has been observed for one year only, but it is well enough. When the meteor has been observed for the first time, such that we knew its orbit? has it been observed before? if yes, why the impact has not been predicted?
  •  
    If you can show that they come from different directions you know that they are not associated, even if you don't reconstruct their orbits.
  •  
    I don't think so. If both objects were part of the same, they would be on different but intersecting orbits anyway, hence different directions. Anyway, I am not knowledgeable in atmospheric entry ... But, with so few information about the object, I am surprised they are 100% certain it is not related to DA14. I think science requires more cautions ... With only the direction they are 100% sure, while the probability of such event is itself extremely small, I am amazed... They can't even predict with 100% certainty where a space debris will fall... plus, nobody consider the object being part of a bigger one that broke up during early entry (which has not been observed) ... so many uncertainties and possible hypothesis... and i am not the only one :) http://www.infowars.com/russian-meteor-linked-to-da14-asteroid/
  •  
    was not that evident to me also but apparently with the right understanding it was quite clear; was amazed also how quickly NASA has published the likely trajectory of the russian object - have a look at it: quite evident that these are not coming from the same body
  •  
    yes, now i get my 100% certainty with the reconstructed orbits nothing else (http://wiki.nasa.gov/cm/blog/Watch%20the%20Skies/posts/post_1361037562855.html) ... I still think that esa anouncemement was highly premature but with a high probability of being right...

Counting whales from space #plos - 1 views

  •  
    The WorldView2 satellite has a maximum 50 cm resolution and a water penetrating coastal band in the far-blue part of the spectrum that allows it to see deeper into the water column. Using an image covering 113 km2, we identified 55 probable whales and 23 other features that are possibly whales, with a further 13 objects that are only detected by the coastal band.

Worlds smallest autopilot (yet) - 1 views

  •  
    The most tiny autopilot in the world was introduced yesterday by the Technical University of Delft, The Netherlands. Named Lisa/s, she comes in at the scales with just a mere 1.9 grams, the 2*2 cm board has everything that a multirotor needs. Among the sensors are a 3 axle gyroscope, compass, barometer and a gps module.

Destroyed Chinese satellite close to ISS: official - Yahoo! News - 1 views

  • If the calculations show that the debris is approaching the station at an unacceptably close range, the six astronauts will receive the order to take shelter in the two Russian Soyuz spacecraft which are docked with the ISS
  • it was already too late to carry out a manoeuvre to "divert the station from the rubbish"
  •  
    hmm, is there info on the size of the "rubbish"?
  •  
    I cannot find more info, but maybe they are just making a lot of fuss of it because it is from the Chinese exploded spacecraft. However, it seems to be a catalogued debris, so it is likely to be in the cm range or more

Condensation transition in networks and other complex systems - 4 views

    I like this work... it mixes physics, networks and biology ! Anyone heard about her ? Here's an interesting paper found on this website: http://nuweb.neu.edu/gbianconi/condensation.pdf

    Eh... Barabasi is really milking the golden cow :) It seems interesting, even if I don't remember enough from my statistical mechanics classes to truly understand it without a major effort. Maybe you could make a layman's science coffee about it?
  •  
    yeah i could if there's enough interest...? do u know Barabasi ?
  •  
    He's quite well known for his work on scale-free networks: http://en.wikipedia.org/wiki/Albert-L%C3%A1szl%C3%B3_Barab%C3%A1si He's applying them for everything and the kitchen sink :) We have a Barabasi-Albert network topology implemented in PaGMO...
  •  
    We worked on this with Luzi a few years back ... while the analogy is original and interesting it fails to capture the dynamics of a network, e.g. if a network has hubs that grow and shrink .... Luzi worked on an extended model to solve this issue, but, if I remember correctly, he got stuck in a computationally very hard problem .... We intended to develop and use the extended model to define relevant characteristic of the ESA network formed by mail exchanges.....

Google's 8-Point Plan to Help Managers Improve - 7 views

    Well, well, Google says it. And all is a result of an algorithm..... Among the interesting fincings the algorithm says that technical competence of the boss is not needed..... against their own beliefs!!

    "Although people are always looking for the next new thing in leadership," he said, "Google's data suggest that not much has changed in terms of what makes for an effective leader."
  •  
    "Managers often want to hire people who seem just like them" does the ACT look like the managers or the managers like the ACT ? hmmm
  •  
    "the topic often feels a bit like golf" What other comparison can one use in an article aimed towards managers? :D
  •  
    nobody in the ACT plays golf yet as far as I know ...

    Which is a pity as you have a golf field not that far away :-D Maybe a good idea for a nice team building event??

Why Randomly-Selected Politicians Would Improve Democracy - Technology Review - 4 views

  • If Pluchino sounds familiar, it's because we've talked about him and his pals before in relation to the Peter Principle that incompetence always spreads through big organisations. Back in 2009, he and his buddies created a model that showed how promoting people at random always improves the efficiency of the organisation. These guys went on to win a well-deserved IgNobel prize for this work.
  • Ref: arxiv.org/abs/1103.1224: Accidental Politicians: How Randomly Selected Legislators Can Improve Parliament Efficiency
  •  
    I think I start to understand why Italian politics does so horribly bad...
  •  
    ... because they don't follow this rule!
  •  
    According to the authors we have four types of people in the parlement: 1) intelligent people whose actions produce a gain for both themselves and for other people. 2) helpless/naive people in the top left quadrant whose actions produce a loss for themselves but a gain for others; 3) bandits whose actions produce a gain for themselves but a loss for other people. 4) stupid people in the bottom left quadrant produce a loss for themselves and also for other people. According to the above definition it is clear that their model does not apply to the italian parlament where we only have stupid people and bandits.
