  • Patent number: 9881430
    Abstract: A system includes plural, different sensors configured to be operably connected to a first vehicle. The sensors obtain status data indicative of a state of a cooling system of the first vehicle. The system includes a digital twin system having processors configured to modify the status data having sampling rates or resolutions that differ such that the status data that is modified has a common sampling rate resolution as that of other data. The processors create a digital twin matrix of the status data. The digital twin matrix is indicative of the state of the cooling system. The processors also determine a health score of the cooling system or simulate operation of the cooling system based on the digital twin matrix. The digital twin system is configured to change or control actual operation of the cooling system based on the health score or the operation that is simulated.

  • Publication number: 20100314752
    Abstract: A method of forming a photonic crystal (PhC) structure and a PhC structure formed by such method. The method comprises forming holes in a Si-based host layer; filling the holes with a high-density plasma (HDP) deposited Si-based oxide and such that a surface of the Si-based host layer is directly covered with the Si-based oxide; performing at least a selective wet etching step for etching the Si-based oxide such that a surface of the resulting PhC structure is planarized.

  • Publication number: 20070240161
    Abstract: A system for dynamically allocating resources in a computing grid is provided. The system comprises a resource management component, a service level agreement (SLA) management component and a job scheduling component. The resource management component is configured to determine availability of a set of resources in a computing grid, for executing job requests submitted by users of the computing grid. The SLA management component is configured to manage service level agreements (SLAs) corresponding to the users and perform a negotiation of resources for the users submitting the job requests, in real-time, based on a resource steerability attribute associated with the job requests. The job-scheduling component is configured to schedule the job requests for the users, based on the resource steerability attribute associated with the job requests. The job requests comprise at least one of a job having batch characteristics and a job having interactive characteristics.

  • Publication number: 20070124237
    Abstract: A method for selecting a target list of customers for making cross sell offers to, for a financial product is provided. The method includes obtaining customer-level information related to one or more members from a historical database. The method then includes building one or more response models and one or more profit models for one or more subsets of members, using the customer-level information. Then, the method includes generating one or more response scores and one or more profit scores for one or more members from a target population, using the one or more response models and the one or more profit models. Finally, the method includes determining a target list of customers for making cross-sell offers to, based on the one or more response scores and the one or more profit scores using an optimization methodology.

  • Patent number: 7042922
    Abstract: A method for calibrating a preferred disposition for a moveable first mirror of an optical switch core of a photonic crossconnect device relative to a second mirror thereof, the method comprising the steps of determining approximate geometric coordinates of the first mirror relative to the second mirror, effecting a laser light crossconnection between the first and second mirrors to produce data from which to provide first order corrections to refine the geometric coordinates, and effecting a further laser light crossconnection between the first mirror and a third mirror, to produce data from which to provide second order corrections to further refine the geometric coordinates, whereby to calibrate the first mirror such that upon initiation of a laser light crossconnection involving the first mirror, a switching element detects deviation of the first mirror from the preferred disposition thereof and effects corrective changes.
