  • Patent number: 10296996
    Abstract: Systems and methods for planning location-sensitive probabilistic behavior based evacuation paths, in a building, from source nodes to sink nodes in a network of routes including a plurality of vertices and edges are disclosed. For example, input parameters including layouts, number of evacuees at each source node, transit time, predetermined time period and maximum capacity associated with each edge and vertex are received. Further, weak evacuation schedules at a state of the evacuees are defined based on the layouts of the building, number of evacuees, transit time and predetermined time period. Furthermore, a strong evacuation schedule is defined based on the weak evacuation schedules and maximum capacity associated with each edge and vertex. Moreover, a mapping is defined from the strong evacuation schedule to the weak evacuation schedules to obtain a probabilistic behavior model. Also, an evacuation path is planned, in real-time, based on the probabilistic behavior model.

  • Patent number: 10216485
    Abstract: A method and system for real-time analytics of sensor-based data is disclosed. Also disclosed is a Cloud-based Paltform-as-a-Service (PaaS) offering for sensor driven applications with services and features for their complete life-cycle management including prompt development, testing, deployment and so forth. The method of the present disclosure enables real-time tracking of various physical parameters and attributes related to smart-spaces using sensor devices implemented in the premises of the smart-space environment and using crowd-sourced user input data. Further, the parameters obtained are sent to the cloud-computing server, wherein the analytics are performed in real-time based on the obtained parameters.

  • Patent number: 9613164
    Abstract: A system and method for storing an input data network, in the form of graph is provided. The system includes a master node and a plurality of slave nodes. The master node is operable to receive the data network in the form of a graph, the graph including a plurality of vertices connected by edges; calculate a probability of co-retrieval for each of the plurality of vertices; and assign each of the plurality of vertices to one of the plurality of compute nodes based on the calculated probability of co-retrieval. Another method and system are provided for converting a dataset into a graph based index and storing the index on disk. Respective systems and methods of querying such data networks are also provided.

  • Patent number: 8296168
    Abstract: System and method for analysis of an opinion expressed in documents on a particular topic computes opinion strength on a continuous numeric scale, or qualitatively. A variety of opinion scoring techniques are plugged in to score opinion expressing words and sentences in documents. These scores are aggregated to measure the opinion intensity of documents. Multilingual opinion analysis is supported by capability to concurrently identify and visualize the opinion intensity expressed in documents in multiple languages. A multi-dimensional representation of the measured opinion intensity is generated which is agreeable with multi-lingual domain.
