  • Patent number: 11238231
    Abstract: A computer-implemented method of establishing influence relationships between data in a question-answering environment is disclosed. Establishing influence relationships can include determining a set of conditions indicating a set of user statuses and analyzing, using a first natural language processing technique, a corpus of data including a set of user data. Establishing influence relationships between data can include identifying, based on analyzing the corpus of data, a set of influence factors corresponding to a subset of the set of user data and to a subset of the set of conditions. In embodiments, establishing influence relationships can include establishing, based on the set of influence factors, a set of influence relationships between the subset of the set of user data and the subset of the set of conditions.

  • Patent number: 10058034
    Abstract: A combine harvester is provided that separates grain material from material other than grain using multiple processing areas, including a harvesting area, a feederhouse area, a threshing area, a cleaning area, and a grain delivery area. In a location at or prior to entering one of the processing areas, the material may be collected and held until a collection threshold is reached. Once it is determined that the collection threshold is reached, the material forming a first group of material may be transported from the location to the processing area or a subsequent processing area. The first group of material is transported from the location to the processing area or the subsequent processing area substantially simultaneously and thus simulates the gathering of a large amount of crop material even when small plots are involved. In this way, reduced cycle times may be achieved, and the efficiency benefits of large-plot harvesting may be extended to small-plot applications.

  • Patent number: 9625599
    Abstract: A downhole acoustic logging tool includes at least one acoustic transmitter and first and second arrays of acoustic receivers deployed on a tool body. The first array of acoustic receivers includes a plurality of axially spaced apart acoustic receivers and the second array of acoustic receivers includes a plurality of circumferentially spaced apart acoustic receivers. A method for making downhole acoustic logging measurements of a subterranean formation includes causing an acoustic logging tool to obtain axial acoustic logging measurements and circumferential acoustic logging measurements. The axial acoustic logging measurements and the circumferential acoustic logging measurements are then processed to compute each of five elastic constants of a transversely isotropic medium.

  • Publication number: 20170099774
    Abstract: The disclosure pertains to separably driven rotor portions for a combine harvester and a method for threshing grain using separably-driven rotor portions. The combine harvester is moved through harvest material comprising grain material and material-other-than-grain (“MOG”). The grain material is separated from the MOG using multiple processing areas. The auger portion may be stopped or rotated at a slower speed with respect to rotation of the threshing portion to simulate the gathering of a large amount of crop material even when small plots are involved, thereby providing the benefits of large-plot harvesting to small-plot applications.
