Hajj Pilgrimage Safety Challenges Crowd Simulator Technology

agent elevator writes: In 2010, Saudi Arabia hosted an international design competition aimed at safely accommodating more pilgrims at Mecca's Grand Mosque. One of the participants told IEEE Spectrum that the crowd densities there (6 people per square meter) bogged down off-the-shelf software so badly that simulation run times were about 10 to 20 times slower than real time crowd movement. Nevertheless, he found some workarounds that gave designers a plan to double the Grand Mosque's peak visitor rate from 40,000 to 102,000 people per hour. Last week's stampede took place well away from the mosque, but signals sent to pilgrims telling them when to speed up or slow down could help prevent such a tragedy, the crowd simulation expert said. Other engineers are turning to fuzzy logic as way to predict how crowds will react in a panic.

    McVeigh's motivation was political, not religious. And somehow it's easy to look at his cause and say: well, he did have a point!

    He said it was revenge for Waco and Ruby Ridge. Stop editing things.

    Atheists murdered about 100 million people in the 20th century, give a take 10 million of so.

    Lenin, Stalin, Mao, the usual crowd.

    People organize their own universe, organize their own energy and decide how to project it into the world eg. preach to their own truth.

    Distortion / Logic / Unconscious Collective, some would say, is just one of 7 levels/arrows for successfully embedding into geometry of space (7 axes of symmetry through tetra-cube which is the physics of the origins of @lph@b3ts)

    which is to say just one way of getting to the zero-point of your inner-self (can meditate, pray, etc etc.all depends on the person)

    when the zero point is coherent, balanced, unbiased, no prejudice (perfect self reference) then one sees others without any bias

    Which some would say is another one of the 7 levels/arrows eg. scalar potential, mind force. etc.

    To choose to repeat and project the contents of these comments above it would appear there is some hang-up in the distortion layer and the poster of the comments are gimbal locked, sorry to say

    When you can get beyond the layer of distortion you get closer to being able to embed accurately precisely perfectly in the cube of space which will give you better vector control to steer... well.. anything really... and you will love everybody...

    the word religion means to 're-connect' back to Source or Cause, which some would say is religion's true purpose...

    but pious and non-pious people alike should realize it's not the end unto itself...

    because there is no end.. and there is no beginning...
