摘要:
A method of controlling a series turbocharger for an engine and a control system for the same includes a boost determination module determining a first predicted boost pressure for a first position of a variable geometry turbine when a high pressure turbine bypass valve is in an open position. The boost determination module determines a second boost pressure for a second position of the variable geometry when the high pressure turbine bypass valve is in the open position. A desired boost module determines a desired boost. A comparison module determines when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure. A bypass valve control module closes the high pressure turbine bypass valve when the desired boost signal is between the first predicted boost pressure and the second predicted boost pressure.

A system for a sequential turbocharger includes a mode selection module, a feed-forward selection module, and a control loop module. The mode selection module generates a control mode signal based on an engine speed signal, an engine torque signal, and an engine mode signal. The control mode signal indicates one of an open-loop control mode and a closed-loop control mode. The feed-forward selection module determines a feed-forward value based on the control mode signal, the engine speed signal, and the engine torque signal. The control loop module determines a loop control value at least one of based on the feed-forward value, a variable geometry turbine (VGT) control signal, and an error signal; and based on a bypass valve (BPV) control signal and the error signal when the control mode signal transitions from the open-loop control mode to the closed-loop control mode.

A method of controlling a turbocharger for an engine and a control system for the same includes a variable nozzle turbine control module operating a variable nozzle turbine of a high pressure turbocharger closed loop in a first load-engine speed region. The system also includes a high pressure turbine bypass valve control module operating a high pressure turbine bypass valve in a closed position in a first load-engine speed region. The variable nozzle turbine control module operates a variable nozzle turbine closed loop in a second load-engine speed region between the first load-speed region and a third load speed region. The high pressure turbine bypass valve module operates the high pressure turbine bypass valve in a transient region in the second load-engine speed region. The variable nozzle turbine control module operates the variable nozzle turbine open loop. The high pressure turbine bypass valve control module operates a high pressure turbine bypass valve in an open position in a third load-engine speed region.

A flame temperature estimator includes an adiabatic flame temperature module that estimates an adiabatic flame temperature. A temperature reduction module estimates a temperature reduction for the adiabatic flame temperature based on an air-to-fuel ratio of an engine. A combustion temperature trend module generates a combustion temperature trend based on the temperature reduction and the adiabatic flame temperature.

A system receives a first part of a response that includes a number of parts, determines whether there is a security issue associated with the first part of the response, stores the first part of the response when there is no security issue associated with the first part of the response, and causes the first part of the response to be transmitted toward a destination when there is no security issue associated with the first part of the response. The system also receives a last part of the response, combines the last part of the response with at least the first part of the response to obtain combined parts of the response, processes the combined parts of the response to determine whether there is a security issue associated with the combined parts of the response, and causes the last part of the response to be transmitted toward the destination when there is no security issue associated with the combined parts of the response.

The present invention provides a device, method, and program for detection of a biomarker candidate that may be used in a diagnosis of a pre-disease state indicating a transition from a healthy state to a disease state. Biological samples are collected from a subject to be measured at different times. Statistical data is obtained by aggregating measurement data obtained in measurement on collected biological samples. Thereafter, a process of obtaining high-throughput data (s1), a process of choosing differential biological molecules (s2), a process of clustering (s3), a process of choosing a DNB candidate (s4), and a process of identifying a DNB by significance analysis (s5) are carried out.
