System for optimizing content queries
An indexing scheme generates a token index associating token index values with keywords in queries and generates expression trees for the queries that use the token index values to represent the keywords. The indexing scheme generates a document index assigning document index values to uploaded documents. The indexing scheme generates a document-token index that associates the token index values with the document index values for the documents containing the keywords associated with the token index values. The indexing scheme applies the expression trees to the document-token index to quickly identify the documents satisfying the queries. For example, the indexing scheme may generate bit arrays for each of the token index values identifying the documents containing the keywords and apply logical operators from the queries to the bit arrays. The resulting data structure provides a list of documents satisfying the queries. |

Clustering based on a directed graph
Various embodiments describe clustering of nodes of a directed graph based on the oriented edges of the directed graph and on a set of rules. In an example, each node represents a device identifier associated with a computing device. The device identifier facilitates an online activity provided by a computing service. A computing system accesses the directed graph and generates clusters that contain subsets of the nodes by at least iteratively updating the directed graph based on the set of rules. The set of rules specifies (i) removal of leaf nodes from the directed graph, (ii) reconnection of nodes that form a chain in the directed graph, and (iii) reconnection of nodes that form a split in the directed graph. The computing system also associates a client profile with a subset of the nodes contained in a cluster from the clusters. |

Logging cache influxes by request to a higher-level cache
Trace logging based on an upper cache layer determining how to log an influx by a lower cache layer. A second cache receives, from a lower layer first cache, a logging request referencing a memory address. The second cache determines whether it has a cache line for the memory address. When the cache line is present, the second cache either forwards the request to a next logging cache layer or causes the cache line to be logged if second cache is the outermost logging layer. When the cache line isn't present, the second cache causes the cache line to be logged when the cache line isn't determined by the second cache to be logged, or when it is determined by the second cache to be logged but it is not determined whether the first cache is aware of a current value of the cache line in the second cache. |

Method and apparatus for reheat dehumidification with variable air volume
The HVAC system includes an evaporator coil and a metering device fluidly coupled to the evaporator coil via a distribution line. The HVAC system includes a variable-speed circulation fan for circulating air around the evaporator coil. A temperature sensor is thermally exposed to the distribution line. At least one controller is operatively coupled to the temperature sensor and to the variable-speed circulation fan. The at least one controller adjusts a speed of the variable-speed circulation fan to increase latent capacity of the HVAC system responsive to a determination that a temperature of fluid in the distribution line exceeds an optimal distribution line temperature. |

Linearization of airflow through zone dampers of an HVAC system
A control system can provide a linear behavior of airflow as a function of damper position of each zone damper in an HVAC system. The control system incrementally closes each zone damper from a fully open position to a fully closed position, and records static pressure measurements with each change in damper position. Then, using a mathematical model that is derived from the second fan law, a correction is calculated for each damper position of each zone damper based on the recorded static pressure measurements to provide corrected damper positions at which the airflow through the zone damper exhibits a linear behavior. The corrected damper positions are stored and used during an operational cycle of the HVAC system to obtain a precise airflow through the zone dampers. |

Network management system and method for automatic registration of network device thereof
A network management system and method for automatic registration of network device thereof are disclosed. The system has an electronic device, a network device and a control host. The electronic device generates and sends configuration data to the network device according to a user operation. The network device automatically generates registration data having device identity data and location identity data, connects to a communication network according to the configuration data, and sends the registration data to the control host via the communication network. The control host determines classification information according to the registration data and configures the device identity data to correspond to the classification information and location identity data for completing registration of the network device. The present disclosed example can effectively omit a registration operation inputted by the user manually via configuring the network device to register at the control host automatically. |
