  • Patent number: 10591484
    Abstract: Highly specific and novel methods for analyzing glycans and proteoglycans are provided. The present invention provides glycan-reactive isobaric Aldehyde-Reactive Tags (iARTs) and the quantification of iARTs-labeled glycans by tandem mass spectrometry. The iARTs have an amine as an active group to react with aldehyde at the reducing end of glycans through reductive amination and demonstrated complete labeling. Due to the isobaric nature of the iARTs, differentially labeled glycans do not differ in mass, and quantitative information is provided by the isotope-encoded reporter ions generated from MS/MS or MS3 spectra. Quantitative information is thus derived from signal of the reporter ions on same precursor. Uses of the information generated by the inventive methods for diagnosis and treatment are also disclosed.

  • Patent number: 10591519
    Abstract: A wind turbine generator fault detection method is described. The method includes acquiring current data from a wind turbine generator during operation, determining frequency demodulated signals and amplitude demodulated signals by frequency demodulating and amplitude demodulating the current data, resampling the frequency and amplitude demodulated signals corresponding to the current data, monitoring a frequency spectra of the resampled frequency and amplitude demodulated signals corresponding to the current data to identify one or more excitations in the frequency spectra. In response to identifying one or more excitations in the frequency spectra at one or more of the variable fault characteristic frequencies, the method includes generating and transmitting an alert that indicates that a wind turbine generator fault is detected.

  • Patent number: 10591520
    Abstract: An alternating current (AC) power flow analysis in an electrical power network. Based on information relating to buses and transmission lines connecting the buses in the electrical power network, a convex approximation of AC power flows in the electrical power network is determined. The convex approximation of the AC power flows comprises convex approximation of nonlinear cosine terms associated with active power components and reactive power components of the AC power flows. A convex objective function associated with the electrical power network is optimised using the convex approximation of the AC power flows.

  • Patent number: 10591527
    Abstract: A method of iteratively screening a sample of electrolytic capacitors having a predetermined rated voltage is provided. The method can include measuring a first leakage current of a first set of capacitors, calculating a first mean leakage current therefrom, and removing capacitors from the first set having a first leakage current equal to or above a first predetermined value, thereby forming a second set of capacitors. The second set can be subjected to a burn in heat treatment where a test voltage can be applied, then a second leakage current of the second set of capacitors can be measured and a second mean leakage current can be calculated. Capacitors having a second leakage current equal to or above a second predetermined value can be removed from the second set, forming a third set of capacitors. Because of such iterative screening, the capacitors in the third set have low failure rates.
