Blades Aren't the Problem
I'm no opponent to wind power, but the blades aren't really the stumbling block with making wind turbines larger and better. We want to build our wind turbines larger as they will rotate slower and capture more energy. The problem is transferring that energy through the hub of the turbine. More energy and slower revolution means huge torque which has to be sped up to generate electricity. Wind turbine gear boxes are still the constraining factor for improvements. Do we have any idea how these designs plan on handling this problem?
If anybody wants to read about an actual attempt to address this, here is a thesis on a system which uses wind turbines to run gravitational pistons to directly generate compressed air.

Link to a Study
Unless you can provide a link, I haven't seen any evidence that talking to someone on a cell phone is different than in person because "your brain is devoted to paying attention to the 'other world.'"
They reference a study done in the UK: (PDF)
http://www.psychology.nottingham.ac.uk/staff/dec/references/inpress.pdfHere's the relevant part. It's not that talking is inherently less distracting, but that someone in the car with you will understand if you're suddenly very quietly intent on driving safely, whereas we are ingrained with a much greater sense of urgency when talking to someone on the phone.
We suggest that during normal in-car conversation, both the driver and passenger will suppress conversation when the demands of the road become too great. However, a remote speaker on a mobile
telephone has no access to the same visual input as the driver, and will be less likelyto pace the conversation according to roadway demandsThe results are interesting. The number of words spoken in an urban area was almost double for a phone conversation versus with someone in the car. There was also more talking on the phone while on a highway ("dual carriageway"), though by a smaller margin. When driving in an urban area, the remote conversation partner asked MANY more questions than an in-car partner. The amount of conversation was very dependent on the type of road, too, which seems (to me) to support the hypothesis that in-car passengers are aware of (and temper their conversation to reflect) driving conditions, whereas remote conversation partners do not.

Re:Speedy little buggers
IANAD, but it seems like you'd have better luck just letting the body's digestive and circulatory systems do the work for you.
Actually, getting drugs past the body's first-pass metabolism is quite a big deal. The stomach, kidneys et al are pretty good at trying to keep toxins/undesirables out of the bloodstream. Getting this stuff into aqueous environments elsewhere in the body helps you skip that step.
As a side-effect, you can administer less drug. For biologics (basically: proteins) this is a big deal for stability, cost of manufacturing, and difficulty of oral administration. For small-molecule drugs those issues don't matter much, but what happens to the stuff that doesn't end up in the bloodstream? Some of it accumulates in the liver or kidneys and a lot ends up back in the water supply (there are plenty of reports now of antidepressents and hormones from contraceptives ending up in the water supply, though a few scary reports notwithstanding it's not clear if they have reached therapeutic levels yet, at least for humans).
Non-disclaimer: I've never heard of these guys and have no idea if they're brilliant, clowns, or something inbetween, nor would you want my judgement on that issue. But I am interested/working on local drug delivery. -
Re:it's a question of open-mindnessI believe that the difference between the groups that this study used was not really the fact that in one group there were "experts" and in the other "non-experts", but that in one group there were "grad-students" and in the other "non-grad-students".
And I believe someone should RTFA before weighing in on it. It wasn't divided into "people who are grad students" and "people who aren't grad students," it was divided into "people who are grad students or researchers in a certain field and are given an article from Wikipedia about that field" and "people who are grad students or researchers in a certain field and are given a random article from Wikipedia's 'Random Article' link in the Navigation Menu on the front page." Or maybe we shall let the study itself explain:
A total of 258 academics (research fellows, research assistants and PhD students) were asked to participate in the study. 69 (27 percent) agreed to take part with 55 (21 percent) actually completing the survey. Each respondent was randomly assigned to one of two experimental conditions. Under Condition 1 they were asked to read an article in Wikipedia that was related to their area of expertise. For example, a member of the Fungal Biology and Genetics Research Group (in the Institute of Genetics at Nottingham University; see http://www.nottingham.ac.uk/biology/Genetics/inde
x .phtml) was asked to look at the article on metabolites. Areas of expertise were found from the academics' own Web sites with the choice of article being made by the author. If there was any doubt the expert was contacted for advice. Under Condition 2 respondents were asked to read a random article. Wikipedia's own random article selection feature was used to assign a different article to each Condition 2 respondent. (http://firstmonday.org/issues/issue11_11/chesney/ )It's very short, so it's not too big of an inconvenience to actually read it.

I was one of teh developers
Hi, I was actually one of the developers of the system. Basically, it doesn`t do it ALL in 1 hour! lol
:) What it did is show hugely visible results in 1 hour. The child would come in to undergo the treratment and after about a month, the eyesight would be near perfect. Each session however would last around 20 - 30 minutes and it was done by giving the eye two images at the same time, with one eye being fed half the game, whilst the other was receiving the other. If you want a direct link to the website, check out this link http://www.virart.nottingham.ac.uk/virart/index.ph p?option=content&task=view&id=36&Itemid=31 Developing the system was a bit of a nightmare. You always had to take into account the fact that there were two of everything and what could/could not be displayed. A logistical nightmare! :) But check out their site and e-mail them. They`re a great bunch of people and would love your questions. -
Re:fear, mostly
After looking at the Introduction to DICOM I think your problem is that DICOM is not a programming language, but is rather a file format, and thus you can't hire a "DICOM Programmer". Any code monkey experienced in basic object oriented work from any higher level language ought to be able to handle all the DICOM work you want- I'd suggest advertising for a Visual Basic programmer if your shop is mainly Windows, or a Java programmer if your shop is mainly Linux. Any higher level programmer can use the freeware and OSS tools linked to from the page above to do whatever you want- you don't actually NEED any experience in DICOM whatsoever to work with the DICOM file format.

Use GRINGO not WAAS
While GPS works everywhere, the Wide Area Augmentation System (WAAS) is only useful for the Continental US. WAAS units will work elsewere but they will only have the resolution of standard GPS. If you need better than standard C/A code accuracy use Carrier Differential (CDGPS) mapping using two Garmin recievers and a copy of GRINGO (http://www.nottingham.ac.uk/iessg/gringo/).
The Garmin Rhino units w/ integrated FRS Walkie Talkie units are vaery rugged and may be handy for survey. Additionally, to quote the Operation Iraqi Freedom
PEO Soldier Lessons Learned report:
Commercial GPS: As is widely known, many soldiers purchase their own GPS systems rather than use the PLGR. The Rhino was provided to the 82d as part of the rapid fielding initiative. Overall, soldiers were very appreciative of this addition to their MTOE. The Rhino was a vast improvement over the PLGR because of the weight, volume, power consumption and performance - the Rhino consistently acquired satellites faster than the PLGR. However, the soldiers stated they did not use the communications capabilities of the Rhino, at least not extensively, because it was not secure and consumed batteries too quickly in this mode.
If it survives the front lines in Iraq, West Africa should be a cake walk. -
Re:Irresponsible statistics: sample space
In addition to "correlation does not imply causality", you also have to consider the sample space. How do they define "blokey jobs" and "caring jobs"? And why did they pick those categories (however they define them) to look at? There was a study that showed that Israeli Fighter Pilots had an 84% of having girl children (which, by the way, seems to contradict the current study). Here's a link to a PDF that discusses this case (among others), and, for the PDF-adverse, here's the Google HTMLization. The point is that "Israeli Fighter Pilots" was chosen as an "interesting" category because of this stand-out statistic.
From my link: "So going back to the Israeli fighter pilots--is it just random chance or is something else happening? To answer this, conventional statistics would set up the obvious sample space (children of fighter pilots), assign probabilities to boy and girl children, and calculate the chance of getting 84 per cent girls in a purely random trial. But this analysis ignores selective reporting. Why did anyone look at the sexes of Israeli fighter pilots' children in the first place? Presumably because a clump has already caught their attention."
Given that neither ABC News Australia nor Illuminating Science is exactly a reputable scientific journal, I would definitely hold off before reading too much into this. I also want to know how they explain the contradiction with the Israeli Fighter Pilot data. :) -
Israeli figther pilots have 84% girls, 16% boys
http://www.psychology.nottingham.ac.uk/staff/jwp/
t eaching/c81mst/readings/amazing.pdf
This NewScientist article above says:
"84 per cent of the children of Israeli fighter pilots are girls"
We should expect results which appear curious if we keep searching through vast amounts of data for curious results. Note that this survey used a small cohort of 3000 people, which is very small in terms of population studies. -
Re:So much for the AMD threats
I wonder if the threats did them any good, or if Intel have now got so used to the cries of wolf that they called Dell's bluff? Intel probably told Dell to shut the hell up or miss out on the launch.
That should read "or if Intel has..."
Company names are singular nouns. Besides not sounding right when you refer to a company name as a plural noun, it's also grammatically incorrect. You are referring to a company, a singular entity. It's a collective noun, like the word "group". While a group consists of individual members, when you refer to the group it is singular.
The only exception would be if you are referring to the individuals within that group.

P2P
I'm an astrophysicist. I read tons of papers all the time. I would really love an easily searchable P2P app for distributing and organising my huge collection of papers and pre-prints. The current web services like ADS are really good but it doesn't a) tie in with papers I've already downloaded and b) allow people who can't afford to pay for papers to download them.
We will still need journals for peer review, sadly. -

Re:IBM Linux Presentation
I used this viewer for a while and found it to be pretty good... isn't RSNA doing a huge teaching file as well?
p.s. you're correct that PACS itself is not limited to Windows - just that depending on the institution, a PACS running on Windows may be the best one to choose (GE's in our case). -
This was my final year project thesis
This was my final year project thesis. Just remember the golden rule unstructured 2 structured == convert 2 XML I wrote a [very bad] program in C++/Perl/tcsh IPC=pipes to add XML tags to English, and then index them into a search engine which would use the lingual data stored in the XML tags to help the search.
NIST does a MASSIVE competition on this annually. I don't want to be an XML-buzzword whore <Arnold Schwarzenegger accent> (XML commando eats Green berets, C++, Java, Perl, COBOL for breakfast)</Arnold Schwarzenegger accent> but you can't beat XML for easily converting anything that you can make sense out of into computer readable format. Real h3cKoRs use SGML, but us underlings have to stick with things we can understand like XML. As for expandability, if we want to encode something else into the document, then just tag-it-and-go
It took me 200 hours to fish out all these links (before the Google days), I don't want anyone to have to waste as much time as I did feeding the search engines exotic foods. It's a year old so pardon me for the odd broken link, armed with these you could probably turn jello into XML ;-)

Re:Earlier webcams
Also known as the Trojan Room Coffee Pot, which is located in the Trojan Room. It was around in 1991, but not connected to the internet (there wasn't one then) until later (see the biography).
A close relative (but much younger) is AT&T Laboratories Cambridge's Smart Beverage Dispenser. It, however, does not yet conform to rfc2324, Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0), and rfc2325, Definitions of Managed Objects for Drip-Type Heated Beverage Hardware Devices using SMIv2, "is not sufficiently flexible to represent the advanced multiple beverage dispenser". But, "Development of a revised MIB supporting multiple dynamic beverage options is under way". Hooray! -

Fantastic facts !!!
"Oh, where to start?"
Just to begin with: spatial resolution within the visual systems of (animals and) humans is properly expressed as an angular measurement, i.e the `number of pixels' equivalent does not compare to the number of pixels you have on your X-windowing system, or whatever - spatial sampling by the eye depends on viewing distance.
In any case, the last I heard there were thought to be the order of 10^6 photoreceptors in each eye.
Without boring you further, I refer you to the following U RL which should lead you to a more comprehensive set of vision research websites.
I would just like to say that there is a tendency to parameterise neural processing which I find personally misleading. Important questions about visual processing concern themselves with functional aspects of the brain. Questions about capacity/resolution/frame rate etc reveal more about our current obsession with VLSI and von Neumann computer architectures than real sensory systems. It's not that clear what big numbers, as in more photoreceptors, high resolution, massive memory etc, actually buy you. Remember that the next time you try to swat a fly.
