On the distribution of squarefree integers in arithmetic progressions

Pierre Francis André Le Boudec

investigate the error term of the asymptotic formula for the number of squarefree integers up to some bound, and lying in some arithmetic progression a (mod q). In particular, we prove an upper bound for its variance as a varies over (Z/qZ)(x) which consid ...

On The Least Squarefree Number In An Arithmetic Progression

Ramon Moreira Nunes

We prove an asymptotic formula for squarefree numbers in arithmetic progressions, improving previous results by Prachar and Hooley. As a consequence we improve a lower bound of Heath-Brown for the least squarefree number in an arithmetic progression. ...

Method and system for combining video sequences with spatio-temporal alignment

Martin Vetterli

Given two video sequences, a composite video sequence can be generated which includes visual elements from each of the given sequences, suitably synchronized and represented in a chosen focal plane. For example, given two video sequences with each showing ...

Method and system for combining video with spatio-temporal alignment

Martin Vetterli, Paolo Prandoni

Given two video sequences (IS1, IS2), a composite video sequence can be generated which includes visual elements from each of the given sequences, suitably synchronized and represented in a chosen focal plane (figure 1). For example, given two video sequen ...

Method and system for combining video sequences with spatio-temporal alignment

Martin Vetterli

Given two video sequences (IS1, IS2), a composite video sequence (15) can be generated which includes visual elements (A, B, 21) from each of the given sequences, suitably synchronized and represented in a chosen focal plane. For example, given two video s ...
