We're all familiar with the high-pitched squeak of basketball shoes on the court during games, or tires squealing on pavement. Scientists conducted several experiments and discovered that the geometry of the sneakers' tread patterns determines the squeak's frequency, enabling the team to make rubber blocks set to specific frequencies and slide them across glass surfaces to play Star Wars' "Imperial March."
Environment minister Mary Creagh said councils had also had a "significant uplift in this year's budget" to help "make this policy a success".，推荐阅读WPS官方版本下载获取更多信息

When using the probability matrix to pick from the candidate set, it is important that the candidate array be sorted in advance. Not doing so will fail to preserve the patterns distinctive of ordered dithering. A good approach is to sort the candidate colours by luminance, or the measure of a colour’s lightness4. When this is done, we effectively minimise the contrast between successive candidates in the array, making it easier to observe the pattern embedded the matrix.
