  • Publication number: 20130231792
    Abstract: A method of controlling energy consumption in a building includes receiving occupancy data including at least one of occupant request data and occupant schedule data, receiving weather data including at least one of current weather measurement data and weather forecast data, generating an output control signal based on the occupancy data and the weather data, and transmitting the output control signal to a building automation system (BAS) of the building. The occupant request data includes a current request, and the occupant schedule data includes a predicted occupant schedule. The output control signal adjusts a building control device in a zone in the building.

  • Publication number: 20130226359
    Abstract: A method including: computing a total cost for a first zone in a building, wherein the total cost is equal to an actual energy cost of the first zone plus a thermal discomfort cost of the first zone; and heuristically optimizing the total cost to identify temperature setpoints for a mechanical heating/cooling system and a start time and an end time of the mechanical heating/cooling system, based on external weather data and occupancy data of the first zone.

  • Publication number: 20130132149
    Abstract: A three-layer model of an engineering system is proposed for developing and evaluating a resilient industrial control system incorporated within the engineering system, the model based upon a group of metrics that are cyclically estimated, operated and evaluated to create a valid resilient arrangement. The layers in the model include a human/operator layer, an automation layer and a process layer, where the industrial control system resides in the automation layer. The metrics are based upon the identification of a number of undesirable incidents, as well a determination of the frequency of occurrence of these incidents, their impact on the performance of the engineering system and the financial loss of the engineering system based upon these undesirable incidents.

  • Publication number: 20130059959
    Abstract: Disclosed is an antifoaming agent for vinyl chloride resin slurry. The agent of the present invention may prevent generation of Fish eyes and deteriorate in production efficiency caused by slurry foams without inhibiting inherent transparency of vinyl chloride resins, in the process of preparing the vinyl chloride resins by polymerizing a monomer mixture containing vinyl chloride as a main component in a polymerization reactor.

  • Publication number: 20120246612
    Abstract: Formal methods are instituted to verify and validate the finite state machine (FSM) of PLC redundancy software. The method and system is implemented through each phase in the lifecycle of the redundancy software; that is, the requirement phase, design phase, implementation phase and, finally, integration phase (including system integration). At each step along the way, the verification and validation process uses tools such as a checklist-based review and inspection, a requirement traceability analysis, formal verification (model checking) and the like to ensure that the created redundancy software is error-free and will perform as intended when implemented in the redundant PLC system.
