Abstract: A multilayer integral geogrid, including one or more cellular layers, has a plurality of oriented multilayer strands interconnected by partially oriented multilayer junctions with an array of openings therein. The multilayer integral geogrid having one or more cellular layers is produced from a coextruded or laminated multilayer polymer starting sheet. The integral geogrid has a multilayer construction, with at least one outer layer thereof having the cellular structure. By virtue of the cellular layer structure, the multilayer integral geogrid provides for increased layer vertical compressibility under load, resulting in enhanced material properties that provide performance benefits to use of the multilayer integral geogrid to stabilize and strengthen soil, aggregates, or other particulate materials.

Abstract: Systems and techniques for providing multilevel autonomous tournaments for wagering game are provided. In some implementations, players may earn entry into such a tournament by meeting one or more criteria and then be associated with a tournament entry for that tournament. Each tournament entry may be associated with a set of tournament entries and, after a requisite number of tournament entries for a given tournament entry set has been associated with players, a selection of a tournament entry, and thus at least implicitly a player, may be made. The players selected in such a selection event may then be associated with a tournament entry in a next-highest tournament tier. Such selections may occur until a single player is selected from the highest-ranked tournament tier of the tournament.
