    Abstract: In general, techniques are described for an RDF (Resource Description Framework) database system which can scale to huge size for realistic data sets of practical interest. In some examples, a database system includes a Resource Description Framework (RDF) database that stores a plurality of data chunks to one or more storage drives, wherein each of the plurality of data chunks includes a plurality of triples of the RDF database. The database system also includes a working memory, a query interface that receives a query for the RDF database, a SPARQL engine that identifies a subset of the data chunks relevant to the query, and an index interface that includes one or more bulk loaders that load the subset of the data chunks to the working memory. The SPARQL engine executes the query only against triples included within the loaded subset of the data chunks to obtain a query result.

    Abstract translation: 一般来说,描述了RDF(资源描述框架)数据库系统的技术,该数据库系统可以扩展到具有实际意义的实际数据集的巨大尺寸。 在一些示例中,数据库系统包括资源描述框架(RDF)数据库,其将多个数据块存储到一个或多个存储驱动器,其中多个数据块中的每一个包括RDF数据库的多个三元组。 数据库系统还包括工作存储器,接收RDF数据库的查询的查询接口,标识与该查询相关的数据块的子集的SPARQL引擎,以及包括一个或多个加载器的批量加载器的索引接口 数据块的子集到工作记忆。 SPARQL引擎只针对包含在加载的数据块子集中的三元组执行查询,以获得查询结果。

    Abstract: Disclosed herein are embodiments of systems, methods, and products comprising a computing device, which provides Efficient Data-In-Transit Protection Techniques for Handheld Devices (EDITH) to protect data-in-transit. An end user device (EUD) may generate a multicast data packet. The EDITH module of the EUD encapsulates the data packet in a GRE packet and directs the GRE packet to a unicast destination address of an EDITH Multicast Router included in an infrastructure. The EDITH module on the EUD double compresses and double encrypts the GRE packet. The EDITH module on the infrastructure decrypts and decompresses the double compressed and double encrypted GRE packet to recreate the GRE packet. The EDITH module on the infrastructure decapsulates the GRE packet to derive the original multicast data packet, and distributes the original multicast data packet to the multiple group member based on the multicast destination address included in the original multicast data packet.

    Abstract: Disclosed herein are embodiments of systems, methods, and products comprise an analytic server, which detects and defends against malware in-flight regardless of the specific nature and methodology of the underlying attack. The analytic server learns the system's normal behavior during testing and evaluation phase and trains a machine-learning model based on the normal behavior. The analytic server monitors the system behavior during runtime comprising the runtime behavior of each sub-system of the system. The analytic server executes the machine-learning model and compares the system runtime behavior with the normal behavior to identify anomalous behavior. The analytic server executes one or more mitigation instructions to mitigate malware. Based on multiple available options for mitigating malware, the analytic server makes an intelligent decision and takes the least impactful action that have the least impact on the system to maintain mission assurance.

    Abstract: A method for improving efficiency of a training program begins with a processor monitoring and adapting execution of a training exercise of the training program. The processor determines a training program effectiveness measure including determining trainee skill improvement demonstrated during the training exercise, and monitoring and determining correctness and timeliness of trainee actions during the training exercise. The processor then determines a training program cost measure by determining a first monetary cost for the execution of the at least one training exercise, determining a second monetary cost associated with trainee man-hours for the training exercise, and generating the training program cost measure based on the first and second monetary costs. The processor then computes a ratio of the training program effectiveness measure to the training program cost measure.

    Abstract: A method and system for determining predictably feasible model designs. The method includes defining a plurality of model designs, wherein the plurality of model designs include a plurality of infeasible model designs, wherein one or more of the infeasible model designs are infeasible due to limits in technology; storing information representing a plurality of technological trends; and classifying one or more of the infeasible model designs as predictably feasible model designs, wherein the predictable feasible model designs are those infeasible model designs expected to become feasible model designs if one or more of the plurality of technological trends continues as anticipated.

    Abstract: An automatic, autonomous, and aircraft-centric interference advisory method is executed entirely on a fist aircraft operating on a movement area of a runway, the movement are including ramps, taxiways, and runways. The method includes a processor onboard the first aircraft computing a first movement projection for the first aircraft using first aircraft data received at the first aircraft; the processor computing additional second movement projections for multiple second aircraft operating on the movement area of the airport using second data regarding each of the multiple second aircraft; the processor detecting a threat to the first aircraft on approach to a defined intersection of the movement area from any of the multiple second aircraft based on a corresponding second movement projection within a configurable time limit of entry into the defined intersection by the first aircraft; and providing on the first aircraft, a threat advisory for a detected threat.

    Abstract: Disclosed herein are embodiments of a cloud data synchronization system enabling an user operating a mobile client device to download mission-specific data sets from a fixed cloud-based server system to a database of the mobile client device, and then use the downloaded data sets independently on the mobile client device when the mobile client device is disconnected from a network connecting to the fixed cloud-based server system. When connectivity to the fixed cloud-based server system is re-established by the mobile client device in an intermittent and bandwidth-limited communication network environment, the fixed cloud-based server system may provide bi-directional data synchronization between records of the fixed cloud-based server system and the mobile client device to update the data sets on the fixed cloud-based server system and the mobile client device while operating in the intermittent and bandwidth-limited communication network environment.
