Abstract: A method and system for increasing call yield and the productivity of agents in an environment such as a contact or call center, for example, is described. Attributes may be used to classify calls and contact information. A system may learn from collected data. Calculations may be performed to aid in forecasting such as probabilities, call yield, and expected call handle time. Such calculations may be used to determine the best time to call a contact to achieve a desired result.

Abstract: This invention relates to methods and apparatus for inducing planes of weakness in hydraulically bound materials, for example roller compacted concrete. A crack inducer vehicle for fabricating pre-cracked hydraulically bound materials, the vehicle comprises: a groove former to form a groove in fresh hydraulically bound material prior to curing, said groove former having a first, lowered position for forming a groove in said fresh hydraulically bound material, and a second, raised position; and a system to apply a de-bonding agent into said groove such that when said hydraulically bound material has cured it preferentially cracks along a said groove.
