The eternal sunshine of the sketch data structure
In the past years there has been significant research on developing compact data structures for summarizing large data streams. A family of such data structures is the so-called sketches. Sketches bear similarities to the well-known Bloom filters [2] and employ hashing techniques to approximate the count associated with an arbitrary key in a data stream using fixed memory resources. One limitat...

متن کامل1 Eternal Universe Karim
In December of 1998, there was published a seminal work using precise measurements of supernovae magnitudes and leading to the conclusion of an apparent accelerated expansion of observed part of Universe. But when we approach the processing of these precise data from a classical ethereal position, without relativistic adjustments, we get another picture, and we believe it is the correct one. It...
متن کاملInflation and Eternal Inflation
The basic workings of inflationary models are summarized, along with the arguments that strongly suggest that our universe is the product of inflation. The mechanisms that lead to eternal inflation in both new and chaotic models are described. Although the infinity of pocket universes produced by eternal inflation are unobservable, it is argued that eternal inflation has real consequences in te...
متن کاملRegulating Eternal Inflation
We present an interpretation of the physics of space-times undergoing eternal inflation by repeated nucleation of bubbles. In many cases the physics can be interpreted in terms of the quantum mechanics of a system with a finite number of states. If this interpretation is correct, the conventional picture of these space-times is misleading.
