... It is generally accepted that the mechanism, widely known as the Antikythera mechanism, was made in Rhodes at the height of the Roman Republic, as the island was known as the source of interesting mechanical automata. You can tell just by looking at it that the device is part of a larger object, and it is also obvious that there are geared wheels and other rotational elements within it. The device undoubtedly is an early computer and could be seen as the first planetarium. ...

... In the first one we suppose that an elementary processor at each step can be corrupted with some small probability, and faults of different processors are independent. For this model, we prove that a parallel computation running on n elementary non-faulty processors in time t = poly(n) can be simulated on O(n log n/ log log n) faulty processors in time O(t log log n). ... r and all step j = 1, . ... 2 To get a circuit that fails with probability e-(n) , we need a linear (log(tn), , , )mixer. ...

SLIDE 1 Coherent beam­beam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchro­betatron modes in the beam­beam system, and thus a head­tail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchro­betatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
