Bi-gram cardinality estimation in a graph database
A method and apparatus for estimating the cardinality of graph pattern queries using graph statistics and metadata is presented. In various embodiments, node and edge labels are used to compute estimates for graph patterns (bi-grams) and the estimates for these patterns as composed to provide cardinality estimates of longer paths. The computation of bi-grams is low cost and requires only minimal changes to the existing query planner in the existing database machinery to be useful. The resulting estimates are used during query execution to minimize the amount of work needed to complete a query and return a faithful and accurate answer to the user. The apparatus includes modules containing computer-executable instructions to perform the above method. |

Self-recovery mechanism for multi-hosts and multi-devices emulation and prototyping system bus
A configuration to address a bus stall during data packet transmission also allows for bus recover due to data packet transmission errors. If a downstream node is not ready to receive data from a buffer of an upstream node, a timer counts a timeout value. The time count increments on each clock cycle in which the downstream node is not ready to receive data. The buffer is cleared at the upstream node when the count reaches a predetermined threshold value. Alternately, the configuration also operates to receive a packet header from an upstream node, the packet header identifying a number of data in a packet. If no data downstream is received on a clock cycle, a counter triggers and is incremented for each cycle in which no date is received. When a threshold is reached dummy data fills a data packet to then transmit the data. |

Interface clock management
The timing of the synchronous interface is controlled by a clock signal driven by a controller. The clock is toggled in order to send a command to a memory device via the interface.

The timing of this signal is not dependent upon the clock signal. Receipt of this signal by the controller indicates that the memory device is ready and the clock signal should be resumed so that a status of the command can be returned via the interface, or another command issued via the interface. |

Relating to lubricating compositions
A lubricating oil composition, a method of reducing low-speed pre-ignition (LSPI) in a direct-injected spark-ignited internal combustion engine, and a use of a lubricant composition to reduce LSPI events in such an engine. Preferably, the composition comprises a detergent comprising an overbased calcium detergent having a total base number (TBN) of at least 150, wherein the lubricating oil composition has a calcium content of at least 0.08 wt. %, based on the weight of the lubricating oil composition, and wherein the lubricating oil composition has a silicon content of at least 12 ppm by weight, based on the weight of the lubricating oil composition. |

Composition and method of manufacturing calcium magnesium sulfonate greases
A sulfonate-based grease composition and method of manufacture comprising (1) addition of both overbased calcium sulfonate and overbased magnesium sulfonate in a ratio range of 60:40 to 100:1, with the magnesium sulfonate added all at once, a portion prior to conversion and another portion after conversion, and/or one more delay periods between the addition of water or other reactive ingredient and the addition of magnesium sulfonate; (2) one or more delay periods between the addition of at least a portion of a facilitating acid and at least a portion of the next subsequently added ingredient; (3) no conventional non-aqueous converting agents added prior to conversion; or (4) a combination thereof. The grease has a high dropping point and reduced thickener yield. |

Marine fuels
An additive composition for a marine fuel or a heating oil comprising a stabilized colloidal dispersion of catalytic metal particles, a neutral or overbased alkaline earth metal detergent and a carrier fluid miscible with a marine fuel oil, a heavy fuel oil, a marine distillate fuel, and/or a residual fuel oil. Also provided are marine fuel and/or heating oil compositions having the additive composition described above and associated methods and uses. |

Reduced fouling of hydrocarbon oil
Antifoulant compositions and methods are used for inhibiting fouling on structural parts of a system exposed to a fluid hydrocarbon or petrochemical stream. Polyamine antifoulants are added to such systems. The polyamine antifoulants may be conjointly used with dispersants and/or fatty acids. The fatty acids have been found to reduce thermal degradation of the polyamine antifoulants. |

Assemblies and methods for enhancing fluid catalytic cracking (FCC) processes during the FCC process using spectroscopic analyzers
Assemblies and methods to enhance a fluid catalytic cracking (FCC) process associated with a refining operation, during the FCC process, may include supplying a hydrocarbon feedstock to first processing units associated with the refining operation. The assemblies and methods also may include conditioning a hydrocarbon feedstock and unit material samples, and analyzing the samples via one or more spectroscopic analyzers. The assemblies and methods further may include prescriptively controlling, via one or more FCC process controllers, based at least in part on the hydrocarbon feedstock properties and the unit material properties, the FCC processing assembly, so that the prescriptively controlling results in causing the FCC process to produce intermediate materials, the unit materials, and/or the downstream materials having properties within selected ranges of target properties, thereby to cause the FCC process to achieve material outputs that more accurately and responsively converge on one or more of the target properties. |

Method of producing pyrolysis oil with reduced impurities
Embodiments of the present disclosure relate to a method of producing pyrolysis oil that may reduce a content of impurities in pyrolysis oil. In the method of producing pyrolysis oil according to the present disclosure, in order to recycle polyethylene terephthalate (PET), monomers are recovered by depolymerizing polyethylene terephthalate with alcohol, and then a remaining depolymerization residue is used as an additive in pyrolysis production of waste plastics, such that a content of impurities in pyrolysis oil may be reduced. |
