Abstract: The present application provides an all-steel snow tire tread, consisting of the following raw materials in parts by weight: 50-80 parts of natural rubber, 20-50 parts of solution polymerized styrene butadiene rubber with dual glass transition temperatures, 40-60 parts of carbon black, 10-20 parts of white carbon black with a high specific surface area, 1-2.5 parts of silane coupling agent, 5-10 parts of modified anti-wet skid resin, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 1-3 parts of anti-aging agent 4020, 1-3 parts of anti-aging agent RD, 1-3 parts of protective wax, 1-1.8 parts of sulfur, and 1-1.5 parts of promoter NS.

Abstract: In some examples, a time-series data set can be analyzed and grouped in a fast and efficient manner. For instance, fast grouping of multiple time-series into clusters can be implemented through data reduction, determining cluster population, and fast matching by locality sensitive hashing. In some situations, a user can select a level of granularity for grouping time-series into clusters, which can involve trade-offs between the number of clusters and the maximum distance between two time-series in a cluster.
