Abstract: An opinion score for a customer associated with a service provider can be determined based on a first function. Parameters of the first function are determined are determined in conjunction with determining parameters of a second function that relates a first probability of a customer behavior event to the opinion score and a third function that relates a second probability of a customer action to an accumulation of the opinion score over a predetermined time interval. The parameters are determined based on one or more values representative of session performance associated with the customer, a measured value of the first probability, and a measured value of the second probability. The parameters are stored in a profile associated with the customer.

Abstract: An apparatus for heating vessels, the vessels having enclosed spaces therein and controlling air ingress into the enclosed spaces through gaps. The method includes providing a lid structure for the vessel having the enclosed space, the lid structure having a burner assembly mounted therein. The burner is configured to provide a predetermined flame diameter. The vessel and lid structure are mated such that the gap is formed between the vessel and the lid structure. Fuel and oxidant are discharged from the burner assembly under conditions to provide the predetermined flame diameter and impart a flame velocity sufficiently large to create an outward gas flow from the enclosed space through the gap and control air ingress.

Abstract: In one embodiment, a counting method of the invention uses an adaptive sketching-update process to compress an unknown cardinality into a counter value that counts the number of binary ones in a hashed bitmap vector. The sketching-update process is probabilistic in nature and uses bit-flip probabilities that are adaptively decreased as the counter value increases. Parameters of the sketching-update process are selected so that the relative error of cardinality estimates obtained based on the counter values is relatively small and substantially constant over a relatively wide range of cardinalities, e.g., from one to about one million. Due to the latter property, the counting method can advantageously be implemented in the form of embedded software that relies on a relatively small, fixed amount of memory.

The burner is configured and controlled to position a region of high heat flux at a position corresponding to an area requiring greater heating, such as the area of maximum charge depth in the furnace to provide substantially uniform melting and heat distribution.
