Abstract: A method of heating a charge material by controlling heat flux in a tilt rotary furnace is disclosed. Combustion by the burner forms a heat release profile including a high heat flux region. The positioning of the high heat flux region is controllable by providing a controlled amount of secondary or staged oxidant. 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.

Abstract: In one embodiment, a method for detecting malicious software agents, such as domain-flux botnets. The method applies a co-clustering algorithm on a domain-name query failure graph, to generate a hierarchical grouping of hosts based on similarities between domain names queried by those hosts, and divides that hierarchical structure into candidate clusters based on percentages of failed queries having at least first- and second-level domain names in common, thereby identifying hosts having correlated queries as possibly being infected with malicious software agents. A linking algorithm is used to correlate the co-clustering results generated at different time periods to differentiate actual domain-flux bots from other domain-name failure anomalies by identifying candidate clusters that persist for relatively long periods of time. Persistent candidate clusters are analyzed to identify which clusters have malicious software agents, based on a freshness metric that characterizes whether the candidate clusters continually generate failed queries having new domain names.

Abstract: An oxy-fuel burner that co-fires liquid fuel and gaseous fuel to create a more luminous flame. The characteristics of a liquid fuel spray and the gaseous fuel and primary oxidant gas flows, as well as the geometry of the burner is adapted to shroud the liquid fuel from the primary oxidant until it exits a precombustor and to prevent the liquid fuel from contacting the walls of the precombustor.
