Abstract: Fault Ride Through (FRT) transient management system configured to enhance the FRT capability doubly-fed induction generator (DFIG)-based wind turbines. A grid side converter (GSC) introduces shunt and series compensation for normal operation and voltage dips, respectively. A braking resistor may be added to smooth switching transients from shunt to series interfaces and dissipate excessive power from the GSC. To attain a flexible control solution for balanced and unbalanced fault conditions, the transient management scheme may employ positive and negative sequence controllers. The system dynamics for the series compensation topology may be analyzed using small-signal linear model. Based on the mathematical model, the controller may be tuned to balance voltage regulation performance and transient stability margins with consideration of various operating conditions.

Abstract: A device and a method for generating input control signals of a serialized compressed scan circuit are provided. A control signal generating device receives a test clock signal from a clock input port and a state enable signal from a state enable bus, and correspondingly generates a shift enable signal, a capture enable signal and a strobe signal.

When the shift enable signal is enabled, the clock gating device controls the test clock signal as a serialized scan clock signal. When the strobe signal or the capture enable signal is enabled, the clock gating device controls the test clock signal as a scan clock signal.

The nucleic acid sequences in the sample are simultaneously amplified, for example, using polymerase chain reaction (PCR) in the presence of an array of nucleic acid probes. The amount of amplicon corresponding to the multiple nucleic acid sequences can be measured in real-time during or after each cycle using a real-time microarray. The measured amount of amplicon produced can be used to determine the original amount of the nucleic acid sequences in the sample.

Abstract: In its various embodiments, the invention provides, first, a composition comprising a vector for transfecting a cell. The vector comprises a first nucleic acid encoding an antisense agent having thereon an RNA interference target for a transcript of a gene endogenous to the cell. The vector further comprises a second nucleic acid that encodes a cell-killing agent. The second nucleic acid further comprises a sequence of nucleotides transcribable into a non-coding region of a transcript of the second nucleic acid, such that the non-coding region becomes an RNA interference target for the antisense agent. In the transfected cell, the vector operates to interfere with the expression of the cell-killing agent unless and until the vector senses certain endogenous gene signals, whereupon it releases the cell-killing agent.
