Next, a second total energy function associated with a second set of aliasing corrections is determined based on calculated second energy functions.

Abstract: Blood flow information is used to reduce noise manifest in blood vessel ultrasound B-mode images. A blood flow signal is obtained by a flow detector. After wall filtering, only the flow signal power in the blood vessel lumen remains, while signal power from stationary tissue region is suppressed. The flow signal component is used to calculate a flow component parameter that is used to generate a gain control signal ? that reduces noise in a B-mode image.

Abstract: In a shift control device for a vehicular continuously variable transmission with an arrangement in which a normal shift mode is switched to an acceleration shift mode in response to an acceleration demand, a shift control is performed to prevent deterioration to running performance due to a transition to the acceleration shift mode by increased running resistance such as ascending road running or the like against a driver will. An acceleration demand determining value PAPL is set depending on a road surface gradient ? such that the shifting mode is more difficult to be switched to the acceleration shift mode in a larger road surface gradient ?, than in a smaller road surface gradient ?.
