发帖数: 4 | 1 This is a unsolved intriguing math question only for real hackers.
The dynamics of a ring network is determined by
d(Xi)/dt = - Xi + max( sum_over_j(Wij * Xj) + bi , 0)
a. neuron i is arranged in a ring network. i = 1,2,...N, and then go back to 1.
N could be very large.
b. max function means
max(x, 0) = x if x > 0,
0 otherwise
c. connection matrix Wij is the connection strength between neuron i and j,
and Wij is only a function the distance between these two neuron |

标 题: 这个貌似简单点：STORAGE RING
发信站: BBS 未名空间站 (Sat Apr 18 21:25:20 2009)
Space Shuttle
Assume the earth's magnetic field of 0.13 Gauss is used to make a storage
ring 190 km above the equator, where the vacuum is pretty good, and the
space shuttle can be used to perform experiments. What (total) energy
protons could be stored in it? The earth's radius is 6350 km.
Give the answer in GeV. |

g*q
发帖数: 26623 | 3 The field is so weak, about 1/100,000 of what we can get from normal
conducting magnets.
p=B*Rho*e, E=pc for relativistic particles.
The earth's magnetic field should provide an energy of about 24GeV, which is
very very low compared to what we have in the storage rings.
Also, the storage rings need strong quadrupole/sextupole magnets for
focusing and enhancing stability, and quite lot more equipments. It's
impossible to be done in the space. |

Adult Female Breeding （Oct-Mar）很像，但是根据时间（我三月底拍的），还有翅

发帖数: 60932 | 31 This was my sons favorite gift this year and this is a terrific price versus
Ebay or Amazon. First off the ring is much bigger then the $15 rings you
normally buy for the figures. Next you get Batista and The Great Khali
figures. Then you get an inside cage which is easy to put together and very
well constructed. If your son likes WWE figures he will love this set.

Explanation: Is this one galaxy or two? This question came to light in 1950 when
astronomer Art Hoag chanced upon this unusual extragalactic object. On the outside is a ring
dominated by bright blue stars, while near the center lies a ball of much redder stars that are
likely much older. Between the two is a gap that appears almost completely dark. How Hoag's

surrounded by a solar "ring of fire". Just such a view was possible for observers in the far

Explanation: The March 3rd total lunar eclipse was widely viewed by denizens
of planet Earth. But only a day before, well placed observers could also
watch a lunar occultation of Saturn as the planet passed behind the nearly
Full Moon. From Selsey, UK, astronomer Pete Lawrence actually saw Saturn
graze the lunar limb, the Moon's bright surface dramatically eclipsing a
substantial part of the gas giant's spectacular rings. |
