Abstract: Disclosed is a method for enhancing the performance of concrete includes, providing a cementitious mixture comprising cement and processed high calcium fly ash; wherein a processing of the processed high calcium fly ash neutralizes a cementitious reactivity of a high calcium fly ash, wherein a pozzolanic reactivity of the processed high calcium fly ash is maintained during the processing of the high calcium fly ash. The processing of the high calcium fly ash includes hydrating and carbonating the high calcium fly ash. The processing further includes excavating the high calcium fly ash from a landfill or surface impoundment after the hydrating and carbonating. Also disclosed is a portland-pozzolan blended cement mixture with clinker, gypsum, and a pozzolanic material, such as processed high calcium fly ash. After processing, the cementitious reactivity of a high calcium fly ash is neutralized, while pozzolanic reactivity of the high calcium fly ash is maintained.

Abstract: A system and method of controlling an automotive vehicle includes generating a reverse direction signal corresponding to a reverse direction of the vehicle and generating brake-steer in response to the reverse direction signal.

Abstract: A system and method of controlling a vehicle with a trailer comprises determining the presence of a trailer, determining a vehicle velocity, determining a steering wheel angle, and determining a rear axle side slip angle. When the rear axle side slip angle is above a predetermined value, the vehicle velocity is above a velocity threshold, and the steering wheel is about zero, brake-steer is applied to the vehicle.

Abstract: According to one embodiment, an active safety control system for a driver of a vehicle is provided when the vehicle is in a first perturbed state. The system generally includes a plurality of sensors, an actuation system and a controller. The plurality of sensors are operable to generate signals which indicate that the vehicle is in the first perturbed state. The actuation system is adapted to change driving conditions of the vehicle. The controller is configured to selectively control the actuation system in response to the signals without driver intervention to change the driving conditions of the vehicle to regain control of the vehicle after the vehicle has entered the first perturbed state.

Abstract: A system and method of controlling an automotive vehicle includes determining a steering wheel angle, determining a steering wheel direction, determining a steering wheel angular rate and applying brake-steer as a function of steering wheel angle, steering wheel angular rate and steering wheel direction.
