Label propagation in graphs
Each node in a subset of graph nodes has an associated label value indicating a characteristic of the corresponding item. Matrix data and graph label data are stored. The matrix data defines a matrix representing the graph. The graph label data defines a graph label vector indicating label values associated with nodes of the graph. For at least one set of nodes, test label data is generated defining a test label vector. A propagation function is defined, comprising a set of basis functions, having respective coefficients. The coefficients are calculated which minimize a difference function dependent on difference between the graph label vector and a result of applying the propagation function to the test label vector for said at least one set. New label values are calculated for nodes in K by applying the propagation function with the calculated coefficients to the graph label vector, thereby propagating labels. |

Adaptive dictionary compression/decompression for column-store databases
Innovations for adaptive compression and decompression for dictionaries of a column-store database can reduce the amount of memory used for columns of the database, allowing a system to keep column data in memory for more columns, while delays for access operations remain acceptable. For example, dictionary compression variants use different compression techniques and implementation options, Some dictionary compression variants provide more aggressive compression (reduced memory consumption) but result in slower run-time performance. Other dictionary compression variants provide less aggressive compression (higher memory consumption) but support faster run-time performance. As another example, a compression manager can automatically select a dictionary compression variant for a given column in a column-store database. For different dictionary compression variants, the compression manager predicts run-time performance and compressed dictionary size, given the values of the column, and selects one of the dictionary compression variants. |

Speculative pre-fetching of flash translation layer tables for use with solid state systems
The present disclosure describes technologies and techniques for use by a data storage controller of a non-volatile memory (NVM) system. In various examples, the controller is configured to perform speculative pre-fetching from a flash translation layer (FTL) table that relates logical addresses to physical locations in the NVM. In some examples, hardware within the controller fetches an entry from an external FTL table based on a provisional FTL address determined using a simplified (quick) address determination procedure and caches the entry internally. This is referred to as speculative pre-fetch. An FTL processor also determines the address of the FTL entry using a full (slower) firmware-based procedure. The FTL processor applies its firmware-computed address to the cache to determine if the entry is cached and, if so, the entry is retrieved from the cache. Otherwise, the entry is retrieved from the external FTL table. In this manner, latency can be reduced. |

Bytecode generation from UML models
Unified Modeling Language is a general purpose modelling language used in the field of software development to easily visualize the systems by specifying the static and dynamic aspects of the system. The conventional way of implementing design models is by writing programs in high level languages like java by a programmer.

The design models comprising of class and activity diagrams after parsing and syntax verification are converted to an autobytecode model. The autobytecode model is further processed to determine the execution sequence comprising of loops, sequential and conditional statements. The execution sequence, the actions and attributes associated with the nodes in the execution sequence are analyzed to automatically generate complete bytecode directly from the autobytecode model created from design models. |

High sensitivity MEMS pressure sensor
We present a microelectromechanical system (MEMS) graphene-based pressure sensor realized by transferring a large area, few-layered graphene on a suspended silicon nitride thin membrane perforated by a periodic array of micro-through-holes. Each through-hole is covered by a circular drum-like graphene layer, namely a graphene “microdrum”. The uniqueness of the sensor design is the fact that introducing the through-hole arrays into the supporting nitride membrane allows generating an increased strain in the graphene membrane over the through-hole array by local deformations of the holes under an applied differential pressure. Further reasons contributing to the increased strain in the devised sensitive membrane include larger deflection of the membrane than that of its imperforated counterpart membrane, and direct bulging of the graphene microdrum under an applied pressure. Electromechanical measurements show a gauge factor of 4.4 for the graphene membrane and a sensitivity of 2.8×10-5 mbar-1 for the pressure sensor specific example described, with a good linearity over a wide pressure range. The present sensor outperforms most existing MEMS-based small footprint pressure sensors using graphene, silicon, and carbon nanotubes as sensitive materials, due to the high sensitivity. |

Further, the FOD screen assemblies provided herein include features that provide for a secure attachment of one or more mesh members to frame members of the assembly. The one or more mesh members are secured to the frame members in such a way that minimal stress is placed on the mesh member at the attachment points. |

Thermoplastic nosecone for a turbine engine
A nosecone for a turbine engine includes a nosecone body and a nosecone mount. The nosecone body extends along an axis between a tip end and a base end. The nosecone body is configured from or otherwise includes thermoplastic material. The nosecone body includes a shell and an arrangement of ribs, which structurally support at least a portion of the shell. A thickness of the arrangement of ribs is greater than or substantially equal to approximately one half of a thickness of the shell. The nosecone mount is adapted to connect the nosecone body to a component of the turbine engine. |

Bypass duct louver for noise mitigation
A bleed air system is disclosed for a turbofan engine having a bypass duct. The bleed air system includes a bleed air conduit having an inlet end connected to the bypass duct and a bleed air flow control valve disposed downstream of the inlet end, and a louver assembly disposed within the opening at inlet end of the bleed air conduit. The louver assembly includes an airfoil-shaped louver blade which extends across the opening in a direction transverse to the flow direction within the bypass duct. A reinforcing rib is attached to the louver blade and extends across the louver assembly in a direction generally parallel to the flow direction. |
