Computational steering is the ultimate goal of interactive simulation. Steering enables users to supervise and dynamically control the computation of an ongoing simulation. We describe CSE: a modular architecture for a computational steering environment. The kernel of the architecture is designed to be very simple, flexible and minimalistic. All higher level system functionality is pushed into ...

Electric fields (EFs) resembling those in the developing and regenerating nervous systems steer growth cones towards the cathode. Requirements for actin microfilaments, microtubules and their interactions during EF growth cone steering have been presumed, but remain unproven. Here, we demonstrate essential roles for dynamic microfilaments and microtubules in cathode-directed migration. Cathodal...

This paper explores the possibility of combining solid state accelerometers with a low resolution position sensor to provide clean estimates of automobile handwheel position, velocity and acceleration for use in force feedback. Typically determining the acceleration and velocity of the handwheel requires differentiating a position sensor such as an encoder or potentiometer. Unless expensive hig...

Active front steering (AFS) is an emerging technology to improve the vehicle cornering stability by introducing an additional small steering angle to the driver's input. This paper proposes an AFS system with a variable gear ratio steering (VGRS) actuator which is controlled by using the sliding mode control (SMC) strategy to improve the cornering stability of vehicles. In the design of an AFS ...

Products and techniques pass through a process of birth, growth, maturity, death and quit the stage like biological evolution process. The developments of products and techniques conform to some evolvement rules. If people know and hold these rules, they can design new kind of products and forecast the develop trends of the products. Thereby, enterprises can grasp the future technique direction...

Dictyostelium discoideum slugs migrating in the absence of external stimuli tend to continue migrating in the original randomly 'chosen' direction. Spontaneous deviations from the starting direction accumulate with time at a rate that measures the 'physiological noise' in the slugs' steering mechanism. Most of the spontaneous turning signals arise in the transduction chain 'downstream' of the c...
