AM Her variables – synchronised magnetic cataclysmic variables (CVs) – exhibit a different period distribution from other CVs across the period gap. We show that non-AM Her systems may infiltrate the longer-period end of the period gap if they are metal-deficient, but that the position and width of the gap in orbital period is otherwise insensitive to other binary parameters (excepting the norm...

In order to meet the safety requirements of automobile braking, improve braking energy recovery rate pure electric buses and increase their driving range, maximum regenerative force that motor can provide is used determine front rear wheel friction distribution curve. A parallel control strategy, A, proposed make full use performance. Aiming at problems low power density short cycle life with a...

The development of hybrid technology can effectively solve the problems high pollution and energy consumption levels automobiles. Therefore, an prediction control algorithm for vehicles based on a minimum equivalent fuel model is proposed. model’s battery power to consumption, sum engine established as objective function. By utilizing these factors, innovative was constructed that could be used...

Removing a clamp force sensor from brake-by-wire (BBW) system designs has been driven by the need to reduce costs and design complexities. In this paper an improved method is presented to estimate clamp force using other sensory information. The proposed estimator is based on the Kalman filter where the actuator resolver is used in a dynamic stiffness model and the actuator current sensors as w...

OBJECTIVE To evaluate biomechanical gait adaptations in dogs after amputation of a pelvic limb. ANIMALS Client-owned dogs (12 pelvic limb-amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. RESULTS Pelvic limb amputees had increased peak braking fo...
