摘要： The claimed subject matter provides a system and/or a method facilitates energy-aware connection distribution among a plurality of servers in a cluster. A set of busy servers in the cluster can be provided that each handle a high number of connections. In addition, a set of tail servers in the cluster can be managed that each maintain a low number of connections. A load skewing component gives priority to at least a subset of the set of busy servers when dispatching new connection requests from a plurality of users. In addition, the load skewing component controls the number of tail servers to maintain a sufficient number for energy-aware operation.

摘要： A method is provided for vehicle to vehicle communication among vehicles having wireless communication links. Upon receiving notification of a sudden change in vehicle behavior, a vehicle broadcasts a priority message to surrounding vehicles within a transmission range. If an emergency event has occurred, a repeat cycle is defined for re-broadcasting the message, and a maximum number of initial repetitions for the message is specified. The message is transmitted repeatedly by a leader vehicle, with a pause between each transmission, until the maximum number of repetitions has been reached.

摘要： The present invention discloses methods for condition-based monitoring of a system and its components using joint time-frequency analysis and signal demodulation. A first method allows construction of models of non-stationary signals having multiple time and frequency scales of interest. In particular, the method uses wavelet analysis to encode essential information in time-frequency transformations and provides a signal model for an operating fault or normal operation of a system of interest. A second method uses the signal models for condition-based monitoring to detect a change in a signal. In this method, the signal models are correlated with sensor signals to determine the operating condition of a system or system component. A third method for condition-based monitoring uses signal demodulation. In this method, a nominal response of a system component is subtracted from a detected signal to more reliably detect subtle changes in the signal due to component degradation.
