20130245351 | RECOVERY METHOD AND SYSTEM FOR DELIVERING EXTRACTED BTX FROM GAS STREAMS - A recovery method and a system for delivering extracted benzene, toluene, and xylene from a hydrocarbon gas stream is provided. The method includes introducing a feed stream of a BTX-rich hydrocarbon gas into an absorber. The method further includes combining, in the absorber, the hydrocarbon gas with an aprotic solvent, such that the hydrocarbon gas and the aprotic solvent are thoroughly intermixed so that the BTX is absorbed into the aprotic solvent, resulting in the production of a BTX-rich solvent and a substantially BTX-free gas. The method further includes vaporizing, using a vaporizer, the BTX-rich solvent to produce a vaporized BTX-rich solvent, and separating, using a distiller, the BTX from the vaporized BTX-rich solvent for delivering the extracted BTX from the hydrocarbon gas. The separation of the BTX from the vaporized BTX-rich solvent also produces a BTX-lean solvent that is recycled back into the absorber as the aprotic solvent. | 09-19-2013 |

20150178633 | SYSTEMS AND METHODS FOR DETERMINING THE UNCERTAINTY IN PARAMETERS OF AN ENERGY USE MODEL - Systems and methods for determining the uncertainty in parameters of a building energy use model are provided. A disclosed method includes receiving an energy use model for a building site. The energy use model includes one or more predictor variables and one or more model parameters. The method further includes calculating a gradient of an output of the energy use model with respect to the model parameters, determining a covariance matrix using the calculated gradient, and using the covariance matrix to identify an uncertainty of the model parameters. The uncertainty of the model parameters may correspond to entries in the covariance matrix. | 06-25-2015 |
20150227870 | SYSTEMS AND METHODS FOR MONETIZING AND PRIORITIZING BUILDING FAULTS - A fault parameter of an energy consumption model is modulated. The energy consumption model is used to estimate an amount of energy consumption at various values of the fault parameter. A first set of variables is generated including differences between a target value of the fault parameter and the various values of the fault parameter. A second set of variables is generated including differences between an estimated amount of energy consumption with the fault parameter at the target value and the estimated amounts of energy consumption with the fault parameter at the various values. The first set of variables and second set of variables are used to develop a regression model for the fault parameter. The regression model estimates a change in energy consumption based on a change in the fault parameter. Regression models are developed for multiple fault parameters and used to prioritize faults. | 08-13-2015 |
20150316907 | BUILDING MANAGEMENT SYSTEM FOR FORECASTING TIME SERIES VALUES OF BUILDING VARIABLES - A building management system (BMS) includes sensors that measure time series values of building variables and a deterministic model generator that uses historical values for the time series of building variables to train a deterministic model that predicts deterministic values for the time series. The BMS includes a stochastic model generator that uses differences between actual values for the time series and the predicted deterministic values to train a stochastic model that predicts a stochastic value for the time series. The BMS includes a forecast adjuster that adjusts the predicted deterministic values using the predicted stochastic value to generate an adjusted forecast for the time series. The BMS includes a demand response optimizer that uses the adjusted forecast to generate an optimal set of control actions for building equipment of the BMS. The building equipment operate to affect the building variables. | 11-05-2015 |

20160109866 | SYSTEMS AND METHODS FOR DETERMINING AN APPROPRIATE MODEL PARAMETER ORDER - A building analysis system includes a communications interface that receives energy consumption data for a building site including energy-consuming building equipment. A processing circuit of the building analysis system calculates first and second regression statistics indicating a fit of an energy use model to the energy consumption data under a null hypothesis that the energy use model has a first parameter order and an alternative hypothesis that the energy use model has a second parameter order different from the first parameter order. The processing circuit generates a test statistic indicating an improvement between the first regression statistic and the second regression statistic, compares the test statistic to a threshold value to determine whether the improvement warrants rejecting the null hypothesis, and determines an appropriate parameter order for the energy use model based on a result of the comparison. | 04-21-2016 |

20090089428 | REDUCING OVERHEAD IN COMPONENT INTERACTIONS - Systems, methods and computer program products are provided for reducing overhead in component interactions comprising monitoring interactions between components residing within a domain boundary; storing data indicative of the interactions; analyzing the data to determine whether there is a first component on a first server and a second component on a second server within the domain boundary that are coupled and dislocated that should be co-located; evaluating available server resources; determining whether the first and second components can be co-located based upon the evaluation of available server resources; and conveying a request to co-locate the first and second components if it is determined that the first and second components can be co-located. | 04-02-2009 |
20090089429 | AUTONOMICALLY CO-LOCATING FIRST AND SECOND COMPONENTS ON A SELECT SERVER - Systems, methods and computer program products are provided for identifying a first component on a first server and a second component on a second server for co-location, where the first and second servers are within a domain boundary; inspecting available server resources within the domain boundary; determining a select server in the domain boundary for co-location based upon the inspection of available server resources; and autonomically co-locating the first and second components to the select server. | 04-02-2009 |
20090106326 | CUSTOMIZED ROLL BACK STRATEGY FOR DATABASES IN MIXED WORKLOAD ENVIRONMENTS - Roll back strategies for database deadlock resolution are customized by identifying a first transaction to a database, identifying a second transaction to the database and detecting a deadlock between the first and second transactions with respect to the database. The deadlock is resolved based upon a predetermined roll back strategy associated with at least one of the first or second transactions to identify a select one of the first and second transactions for roll back and a request is conveyed to roll back the selected one of the first and second transactions, wherein the preferred transaction is allowed to continue processing. | 04-23-2009 |
