摘要:
A method for detecting power consumption anomalies. The method obtains two different time power series and compares them to generate a dissimilarity matrix. A dimensionality reduction equation is applied to the dissimilarity matrix to obtain a low dimensional embedding of the power data. A probability score of each of the time series being anomalous is then calculated.

In an embodiment, a device characterization system includes a sensor to sense an attribute of a device, a processor, and an algorithm executable on the processor to collect time series data of the attribute from the sensor, detect edges in the data, identify clusters from the edges, label the clusters based on input from a supervisor, and estimate device characterization parameters from the clusters.

Determining sensor placement in distributed networks includes identifying measurement locations in a distributed network with a tree topology and selecting a subset of the measurement locations for sensor placement with a mutual information function.

Pixels representing attributes of data records are into discrete rings of a graphical visualization, where the discrete rings correspond to respective ones of the attributes, and where the pixels are arranged in each of the discrete rings according to time intervals of the data records. A correlation ring is provided in the graphical visualization in addition to the discrete rings, where the correlation ring has visual indicators for indicating degrees of correlation between at least two of the attributes.

A system for managing utilization of biogas in an infrastructure includes a plurality of biogas implementing apparatuses. The system also includes a biogas source to supply biogas to the plurality of biogas implementing apparatuses and an optimizer to determine a distribution of the biogas to the plurality of biogas implementing apparatuses that substantially optimizes at least one metric associated with operating the infrastructure.

A system for managing a structure having cooling fluid configured to flow around and absorb heat from components contained in the structure includes a plurality of separate cooling mechanisms configured to absorb heat from the cooling fluid. At least two of the plurality of separate cooling mechanisms have at least one different level of a metric with respect to each other. The system also includes a controller configured to implement the plurality of separate cooling mechanisms in a staged manner to remove heat from the cooling fluid. The staged manner includes implementing the cooling mechanism having a relatively lower at least one metric level first and implementing a cooling mechanism having a relatively higher at least one metric level last, to cool the structure.
摘要:
In a method of estimating a replacement cost associated with an existing technology performed by a processor, one or more costs associated with implementing the existing technology are obtained, in which the one or more costs include an environmental cost and a utility cost associated with implementing the existing technology. In addition, an existing net benefit of continuing implementation of the existing technology based upon the obtained one or more costs are calculated.
