Abstract: The present invention relates to a method for detecting a ground fault in an inverter. The method for detecting the ground fault in the inverter in a current detection using leg-shunt resistors includes detecting output currents of three phases of the inverter, determining whether or not a voltage utilization of the inverter is not less than a preset allowable voltage level, and determining an occurrence or non-occurrence of the ground fault on the inverter.

Abstract: The invention provides methods for the synthesis of eribulin or a pharmaceutically acceptable salt thereof (e.g., eribulin mesylate) through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Homer-Wadsworth-Emmons olefination), Dieckmann reaction, catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic intermediate. The invention also provides compounds useful as intermediates in the synthesis of eribulin or a pharmaceutically acceptable salt thereof and methods for preparing the same.

Abstract: A method and system for controlling a fuel cell vehicle are provided in which a bidirectional converter monitors a state of a fuel cell vehicle in real time to improve control responsiveness in a transient state of the fuel cell vehicle. The method includes receiving, by a bidirectional converter, a command for a current limiting value in the high voltage battery from the fuel cell controller while the fuel cell vehicle is driven. In addition, the bidirectional converter is configured to determine whether the fuel cell vehicle is switched to a predetermined mode and change the current limiting value of the high voltage battery. A predetermined control is performed by the bidirectional converter based on the changed current limiting value when the fuel cell vehicle is switched to the predetermined mode.

Abstract: A method and a system for controlling a reverse link rate by using the number of active users who are carrying out communication in a CDMA 1xEV-DO mobile communication system is disclosed. A value of rise-over-thermal (ROT) at each antenna end of a wireless base station is measured and compared with a threshold ROT which defines an allowable limit of the ROT. A reverse activation control bit is set as 0 if the measured ROT value is smaller than or equal to the threshold ROT. The number of the active users is compared with a threshold user number which defines an allowable limit of the active users if the measured ROT value is greater than the threshold ROT. The reverse activation control bit is set as 0 if the number of the active users is smaller than or equal to the threshold user number. The reverse activation control bit is set as 1 if the number of the active users is greater than the threshold user number.
