  • Publication number: 20220196850
    Abstract: A time-free position determination of a roving receiver includes acquiring from a snapshot receiver in a cloud executing process, a snapshot position of the snapshot receiver received by the snapshot receiver for a single epoch from a constellation of global positioning satellites, the snapshot position including a multiplicity of time-free observables. The method additionally includes retrieving into the cloud executing process baseline position data for a fixed receiver received from the constellation and comprising time-referenced observables. Finally, the method includes compositing in the cloud executing process the time-free observables of the snapshot position with the time referenced observables of the baseline position data to produce time and position data for the snapshot receiver.

  • Patent number: 11361028
    Abstract: A technique produces a graph data structure based on at least partially unstructured information dispersed over web documents. The technique involves applying a machine-trained model to a set of documents (or, more generally “document units”) to identify topics in the documents. The technique then generates count information by counting the occurrences of the single topics and co-occurrences of parings of topics in the documents. The technique generates conditional probability information based on the count information. An instance of conditional probability information describes a probability that a first topic will occur, given an appearance of a second topic, and a probability that the second topic will occur, given an appearance of the first topic. The technique then formulates the conditional probability information in a graph data structure. The technique also provides an application system that utilizes the graph data structure to provide any kind of computer-implemented service to a user.

  • Publication number: 20220179894
    Abstract: A method may include obtaining a set of documents. Text objects from a text object database generated based on the set of documents may be compared to a search term object to identify relevant text objects that match the search term object. A context object for each of the relevant text objects that indicate usage of the relevant text objects within the documents corresponding to the relevant text objects may be determined, and context objects may be grouped according to similarities between the context objects. A first or second classification may be applied to each context object based on one or more criteria, and the first and second classifications may also be applied to each group based on the classifications of the context objects within the groups. Documents within the set of documents may be given the first or second classifications based on relations and similarities to the classified groups.

    Abstract: A method for preparing an accelerator for sprayed mortar/concrete is provided. The accelerator includes an organic component, inorganic component aluminum sulfate, an initiator, and a reductant. The organic component in the form of a polymer monomer is added to concrete and polymerized into a polymer network structure in the presence of the initiator and the reductant; and the inorganic component aluminum sulfate promotes rapid hydration of the concrete to form an inorganic network structure. Such organic-inorganic interpenetrating network thickens a cement-based material rapidly to achieve strong adhesion, fast-setting and hardening properties and effectively reduces resilience of the sprayed mortar/concrete. The accelerator prepared by the method is well compatible with all sorts of cement, efficient and environmentally friendly.
